Evaluation of Efficiency and Response of Quinoa Plant to Nitrogen Fertilization levels

Abdulrahman M. Almadini, Ayman E. Badran and Abdullah M. Algosaibi

ABSTRACT: A field experiment was conducted to evaluate the response of the quinoa yield to nitrogen (N) fertilization, the nitrogen use efficiency (NUE) as well as the correlation coefficient to determine the important traits that contribute in determining the productivity of quinoa crop. Three levels of N fertilizer (i.e., 0, 80 and 160 kg N ha-1) were used and laid out in a randomized complete block design with four replicates. The results showed that all tested characteristics were significantly increased with increasing N fertilizer treatments showing grain yields per plant varying from 2.48 to 18.08 g plant-1 and grain yields per hectare ranging from 101.23 to 770.2 kg ha-1. In contrast, NUE was significantly reduced with increasing N fertilizer rates from 5.52 to 4.31. The results indicated that there were significant effects of treatments on some chemical components in grains at 0 and 160 kg N ha-1 (i.e., 14.81 and 17.13% protein respectively); N, phosphorus (P) and potassium (K) contents in grains, roots and stem. According to the correlation between the vegetative traits and grain yield kg ha-1 varied from 0.95 for no. of leaves plant-1 to 0.99 for chlorophyll content, fresh weight plant-1 as well as leaf area. Also, the simple correlation among agronomic and chemical traits had significant and positive relations with the grain yield kg ha-1 under the investigated N treatments with an exception of P content that recorded a relatively high negative correlation with grain yield ha-1 (-0.589). It may be concluded from obtained results that dry weight as a vegetative trait, grain yield plant-1 as an agronomic trait and the ash as a chemical trait should be taking in considerations suggesting the importance of direct selection for these traits as important ones with grain yield ha-1 under studied treatments.

Abou Seeda M.A., A.A. El-Sayed, Yassen A.A., Sahar M. Zaghloul and A. Khater

ABSTRACT: Heavy metals represent a portion of important environmental pollutants that can causes significant damage to the environment and human health as their solubility and mobility. Main sources of soil contamination are reviewed. Selection the most appropriate soil and sediments remediation technology depends upon soil characteristics, type of pollutant and concentration to be removed and the end use of contaminated medium. This paper will review both approaches and technologies of removing contaminants from eco-system. Remediation of heavy metal contaminated soils is necessary to at least minimize the affiliated risks, and make land resource always available for agricultural production, enhancing food security and scale down land interval problems arising from changes in the land use pattern. The main technologies were found to be used for heavy metals removal from contaminated soils are: solidification/stabilization (S/S), electro kinetics and in-situ extraction. Soil characteristics, especially texture, organic matter and pH are of great importance in selecting the most appropriate remediation method. Phytoremediation can be also used. The principles, advantages and disadvantages of soil remediation techniques, which are frequently listed among the best-demonstrated available technologies for cleaning up heavy metal contaminated sites, are presented.

The dual inoculation with Rhizobium sp. and cyanobacterial extracts enhances the common bean (Phaseolus vulgaris L.) responses to white rot disease caused by Sclerotinia sclerotiorum

Nagwa M. M. El-Khateeb and Yasser Nehela

ABSTRACT: In this study, laboratory and greenhouse experiments were conducted to investigate the suppression effect of two biocontrol agents caynobacterial (Spirulina sp., Nostoc linckia and Anabaena variabilis) extracts, along with Rhizobium leguminosarum biovar phaseoli, against Sclerotinia sclerotiorum in common bean plants. Four isolates of S. sclerotiorum were tested for pathogenicity in bean plants, and all isolated fungi proved to be pathogenic and caused white rot symptoms. Results of in vitro studies showed that algal extracts significantly inhibited the mycelial growth of the pathogen when compared to the untreated control. N. linckia gave the highest reduction (56.29%), followed by A. variabilis (51.85%) and Spirulina sp. (45.93%), respectively compared to control (0%). In greenhouse experiments, the combined effect of Rhizobium sp. and cyanobacterial extracts significantly reduced disease incidence and severity under artificial infection with S. sclerotiorum. The treatments showed the maximum effects for controlling disease incidence and severity caused by S. sclerotiorum, which were in the range of 13.33 to 26.67 % and 1.24 to 1.82, compared to 73.33 and 4.50 % in infested control, respectively. In addition, these treatments increased number of nodules, plant height, root length, fresh and dry weight of shoots, N2 % and total nitrogen compared to control. The effects were
similar to those of the fungicide Vitavax, which reduced the disease incidence and severity but adversely affected Rhizobium sp. and the symbiotic N2 fixing parameters. Considerable increases in activity of oxidative reductive enzymes (peroxidase and polyphenol oxidase) were recorded in plants grown from treated bean seeds.

Evaluation of Photosynthetic Capacity and Grain Yield of the Sea Level Quinoa Variety Titicaca Grown in a Highland Region of Northwest Argentine

Juan A. González, Sven E. Jacobsen, Sebastián E. Buedo, Luis E. Erazzú, Daniela A. González and Fernando E. Prado

ABSTRACT: Photosynthetic characterization of the quinoa cultivar Titicaca grown at the Encalilla site (1995 m asl), a high mountain valley of the Argentinean Northwest, is described in this study. Titicaca cultivar, bred in Denmark from Chilean and Peruvian parenteral lines, is a promising short cycle cultivar and daylength neutral photoperiod. Results showed that maximal photosynthetic CO2 assimilation (Amax) and stomatal conductance (gs) were similar to other quinoa varieties. However, carboxilation capacity and leaf transpiration (E) were significantly higher in Titicaca cultivar compared with other quinoa cultivars grown in the same place. Assimilation of CO2 and stomatal conductance exhibited a strong correlation, like that occurs between (E) and (gs). Light saturation point (LSP) and light compensation point (LCP) were higher in relation to other quinoa cultivars. Grain yield of 2.35 and 2.51 g/plant was recorded and indicating a well adaptation to arid climatic conditions of the Argentinean Northwest region. The highest value of UV protective pigments found in Titicaca will be explained by solar irradiance in the grown area in relation to Denmark conditions. Grain yield, harvest index and some physiological parameters suggested a good adaptation of the Titicaca quinoa cultivar to high mountain valleys of the Argentina Northwest. This means that Titicaca may be considered as a good alternative for farmers in order to get similar production in less time.

Fowziya M. Ali, Miftah S.M. Najm

ABSTRACT: Periodontal disease is extremely common oral disease among dentate population. The occurrence and degree of severity of periodontitis is closely related to the early control of gingivitis at early stages of life. This study was aimed to investigate the periodontal health status of Libyan children group who attending children department at the faculty of dentistry at University of Benghazi. Also to validate using gingivitis extent (GE) and gingivitis severity (GS).in evaluating periodontal status of various group children. to serve as a data base for future studies. Subjects and Methods: Two hundred and eight children (mean age of 8.0) were included in the study. The samples were subdivided into 3 age groups (42 children in <6yrs old, mixed dentition 6-12 yrs old n=139) and older group (>12 yrs old n= 27). Non-invasive and simplified procedures to examine their periodontal health and caries experience were used. Both the extent and the degree of gingivitis severity were assessed in the incisor area of the maxilla and the incisor and canine area of the mandible in the anterior teeth by using gingivitis extent (GE) and gingivitis severity (GS) indices. The individual gingival units (papillae (P), Margins (M) and attached gingivae (A) were assessed for the presence of inflammation based on visual examinations. The extent of inflammation was measured by scoring the colour change of the most severe gingival unit in both index teeth and forming a mean for both jaws. The caries experience was assessed by using dmft for deciduous teeth and DMFT for permanent teeth. Gngivitis extent and gingivitis severity indices were assessed and majority 206 (99%) out of 208 of children suffered from different degrees of gingival inflammation. Conclusion: There has been more untreated caries and more pronounced gingival inflammations of various degrees in this sample due to the lack of proper dental care.

ABSTRACT: The current study was carried out as a preliminary study to determine the incidence of cytological endometritis (CE) and to investigate its effects on pregnancy in dairy cows. Forty nine dairy cows belonging to two farms were included in the study. Cows were enrolled between 28-42 days in milk (DIM) in farm 1 (n=25), while in farm 2 (n=24), some cows (n=8) were enrolled at DIM>200. Cows were fed three times daily on totally mixed ration (TMR) and were milked three times using automatic parlours. Uterine samples were obtained from examined cows and were stained with Diff-Quick stain to determine the percentage of polymorphonuclear cells (PMN). A PMN% greater than 18 was taken as indicator of CE. Data pertaining to parity, breed, milk production, conception were obtained from automatic records. Results showed numerically higher incidence of CE in Holstein cows and in low producing cows. In addition, postpartum problems during the first ten days as retained placenta and metritis increased the incidence of CE in examined cows. Furthermore, CE was associated with numerically higher figures of culling among cows and cows with CE achieved lower pregnancy rates, compared to those without CE.

M.M. EL-Tanany and Hanaa Refai Abdallah

ABSTRACT: A field experiment was performed during growing seasons of 2016/2017 and 2017/2018 in a private orchard located at Kafr Shukr, Benha Center, Qualyubia Governorate, Egypt. The investigation was conducted on 50-years-old of Valencia orange trees (Citrus sinensis L. Osbeck) budded on sour orange (Citrus aurantium L.) rootstock. The treatments were T1: control treatment (sprayed with water). T2 and T3 : trees sprayed with potassium sulphate 1% and 2% .T4 and T5 : trees sprayed with salicylic acid at 100ppm conc. and 200ppm,respectivelyT6 and T7:trees sprayed with Oleic acid at250ppm and 500 ppm conc.; respectively.T8 and T9 :trees sprayed with phenylalanine at 200 ppm and 300ppm; respectively.T10: spraying trees with a mixture of (K2SO4 1%+SA 100 ppm + Oleic acid 250 ppm+Ph 200 ppm).T11:spraying trees with a combination of(K2SO4 2 %+SA200 ppm + Oleic acid 500 ppm + ph 300 ppm ). The results proved that foliar application with a mixture of (K2SO4 2% + SA200p pm + Oleic acid 500ppm +ph 300 ppm) produced significantly the highest fruit yield ; expressed as weight and significantly increased peel and pulp weights and fruit juice volume when compared with the control treatment and other foliar application treatments. Moreover, the aforementioned treatment; also improved fruit volume, fruit length. However, fruit diameter character was the highest by foliar application with Oleic acid at 500ppm concentration. This was true during both seasons of the study. As for fruit shape index, Oleic acid 500 ppm, ph 300 ppm treatment was significantly supremacy than other treatments in the both seasons. All treatments reduced percentage of weight loss, decay % during the storage period compared with the untreated fruits (control) during both seasons. Moreover, trees sprayed with a mixture of (K2SO4 2%+ SA 200 ppm + Oleic acid 500 ppm + ph 300 ppm) significantly reduced fruit decay percentages and markedly increased fruit peel thickness compared with the control treatment (water spray) and all other treatments and the difference was significant. Vitamin C was decreased with prolonging the storage period of the fruits. All treatments reduced the loss of vitamin C in fruits during storage period compared with control. The acidity content was gradually decreased with the storage period during the investigated seasons. Vice-versa, fruit total soluble percent and TSS/acid ratio greatly increased with increasing storage period. Both total soluble solids % and vitamin C content in fruit juice were increased when trees sprayed with a mixture of (K2SO4 2%+ SA 200 ppm + Oleic acid 500 ppm + ph 300 ppm ) followed by trees sprayed with Oleic acid at 500ppm concentration.
Besides, fruit total acidity and TSS/acid ratio significantly augment by spraying trees with this treatment. In addition; foliar application with phenylalanine at 300ppm significantly enhanced the ratio of TSS/acidity of Valencia orange fruits.

Enhancing Extractable Phosphorus from Phosphate Rock in Some Soils by Amending With: Organic Acids, Sulfur, Farmyard Manure, Ammonium Thiosulfate and Phosphate Solublizing Bacteria

A.S. Taalab, Sh. Sh. Holah, S.T. Abu Zeid, Hanan S. Siam and Eman A. Abd El- Rahman

ABSTRACT: Phosphorus is an important plant nutrient and therefore has a major impact on the productivity of agriculture. Phosphate rock is spread as natural mined rock in many locations around the globe and in Egypt's western desert. Depending on the source of the mine, the significance of phosphate rock is linked to its elevated phosphorous element content from 16 to 25 percent of P2O5. Many approaches and techniques have been followed for the treatments of phosphate rock to get benefits of its content from extractable phosphorous. A set of laboratory experiments were conducted to investigate phosphate-dissolution ability from phosphate rock (PR) in clayey and sandy soils as a function of incubation time. The different amendments used in this study oxalic acid (OA), citric acid (CA), sulfur (S0), farmyard manure (FYM), ammonium thiosulfate (ATS) and phosphate solublizing bacteria (PSB) and incubated at 25°C for 14, 28, 42, 56 and 70 days. The obtained results indicated that the availability of P from phosphate rock was increased by increasing incubation time up to 70 days. The useful data gained refers to the fact that blending organic acids, sulfur, ATS, FYM or PSB with phosphate rock considerably significantly enhanced extractable P over PR alone. In example, incubation PR with oxalic acid increased extractable P in clay and sandy soil by 3.49 and 5.2 times that of the treatment PR alone, respectively. Moreover, pH of all the added amendments in clayey and sandy soils tended to decline with time, except control, PR or SSP. In comparison with PR alone, the pH obtained from PR with oxalic, citric, sulfur, ATS, FYM and PSB decreased significantly at the end of incubation.

Anter, A.S.

ABSTRACT: Drought and weeds are both of the most important abiotic and biotic stresses that affect sesame yield under Egyptian conditions. And climate change requires plant varieties with more adapted to drought for sustainable development where drought-tolerant varieties will offer great yield stability and possibly reduced the weed competition. The objectives of this study were to identify high yielding, to investigate reaction to drought stress of six advanced lines of sesame (F8 and F9 generations) along with commercial cultivar Shandaweel (C) and the effect of drought on Xanthium strumarium and Cynodon dactylon weeds to the extent cultivated of sesame in the marginal lands. The study was applied over two seasons (2016 -2017) at the Agriculture Experiments and Research Station, Cairo University. Genotypes arranged in a randomized complete block design with three replicates under drought and normal conditions. Five traits, days to maturity based on plot, seed yield acre-1, oil percentage, oil yield acre-1 and root-shoot length ratio and the dry weight of X. strumarium and C. dactylon weeds calculated. Genotypes showed a highly significant variation (p < 0.05) for all the studied traits except day to maturity under drought conditions in the 2016 season. Three traits, oil yield acre-1, seed yield acre-1, and root-shoot length ratio recorded the higher values of phenotypic and genotypic coefficients of variability connected with high heritability and genetic advanced indicating that additive gene action was controlling in them. Two lines C1.6 and C1.8 were earlier, on average, than C by 5.2 and 5.3 days in F8 and F9 generations respectively. Mean performance of the line C3.8 for three traits, seed yield acre-1 (624.1 kg), oil yield acre-1 (316.0 kg) and root-shoot ratio length (66%) was higher than other genotypes under normal and drought conditions consequently, classified as drought tolerant. Correlation coefficients results indicated that a direct selection for seed yield would be effective to identify drought-tolerant sesame varieties under drought conditions. Also, lines have negative effects on the dry weight of X. strumarium and C. dactylon weeds under drought conditions. To confirm these results, several locations and years are needed to estimate the interaction between lines and two weeds. Finally, line C3.8 offering prospects to the form of new varieties having high-yield, highly drought tolerant and compatible with stored moisture environments.

Impact of Spraying Lithovit and Different Irrigation Levels on Growth, Blooming and Fruit Setting of Manzanello Olive (Olea Europaea L.) Cultivar

Dobiea I.M., H.E.M. El-Badawy, S.F. El-Gioushy and A.A.H. Hegazy

ABSTRACT: Water stress is one of the main challenges which constrain olive cultivation in reclaimed area in Egypt. It can impair the growth and production performance of olives. Many investigations recommended spraying Lithovit to reduce the effect of water stress. We believe that we have designed an innovative solution to follow up the effect of spraying Lithovit (Ca CO3 & Mg CO3) on olive trees which exposure to different irrigation levels. Four concentrations of Lithovit were sprayed on olive (Olea europaea var. Manzanello) trees (0, 2, 4 and 6 g/L) under three irrigation levels (50, 75 and 100% of evapotranspiration for crop “ETc”) during 2017, 2018 seasons. Strong evidence of irrigation at 75% of ETc was found on olive growth, blooming and fruit setting. It was the best irrigation level to balance between vegetative growth and blooming. Moreover, there were significant variations between spraying Lithovit at 2 g/L and other concentrations on Blooming and fruit setting. Furthermore, the interaction between spraying Lithovit and irrigation levels cleared that spraying Lithovit at 2g/L and irrigation at 75% of ETc enhanced blooming and fruit setting. On the other hand irrigation at 100% of ETc with spraying Lithovit at 2g/L improved the vegetative characteristics.

Lactoferrin addition to Tris-extender reduces the detrimental effects of cryopreservation on Egyptian buffalo semen

Hussein Y.S., Shaba M.I. and El-Sheshtawy R.I.

ABSTRACT: The freeze-thaw process results in structural and functional damages caused by over accumulation of reactive oxygen species (ROS). Addition of exogenous antioxidants to semen extender is of a great importance to overcome the oxidative damage during the freezing protocol. Objective: To evaluate the effect of tris-extender supplemented with a different concentrations of Lactoferrin on buffalo bull semen preservability. Methods: Different concentrations of lactoferrin (2mg/ml, 4mg/ml and 6mg/ml) were added to tubes containing Tris–citrate egg yolk extender with 20% (v/v) egg yolk and 7% (v/v) glycerol. The control tubes were Tris containing (0 lactoferrin). The extended semen was subjected to semen freezing protocol. Semen assessment including motility, viability%, abnormality%, intact of sperm membrane (hypo-osmotic swelling test) and acrosome status were carried out for both cooled and frozen semen. Results: The post cooling results revealed non-significant improvement in sperm membrane integrity (HOST) of all used lactoferrin concentrations, especially for TL1 (72.46±0.46) compared to control (56.61±8.93). Other sperm parameters were kept as the control. After thawing, sperm motility exhibited improvement (P<0.009) for all concentrations of the used lactoferrin addition (58.33±1.66, 51.66±1.66 and 53.33±3.33 respectively) as compared to the control (43.33±1.66). Sperm viability percent was improved (P<0.002) in TL1 (86.66±1.66) when compared to the control (80.66±0.66). Moreover, a significant reduction (P<0.004) in sperm abnormalities were observed in TL1 (8.66±0.33) and TL3 (8.33±0.33) when compared to the control (10.33±0.33). Sperm membrane integrity (HOST, 57.48±11.68, 58.37±3.72 and 69.51±3.91) was kept as the control (57.90±0.27) and acrosome intact percent (89.33±1.15, 88.66±3.21 and 89.66±4.50) was maintained as control (87.50±5.00). Conclusions: The concentration of lactoferrin (TL1, 2mg/ml extender) exhibited the best sperm quality in post-thawed semen process.

Exogenous application of 24-epibrassinolide and spermine improves growth and yield of drought stressed wheat (Triticum aestivum L.)

Zeid F. A., El Shihy O. M. and Ibrahim F. A.

ABSTRACT: The present study was conducted to investigate the effect of foliar application of 24- epibrassinolide (EBL) and spermine (Spm) on growth, yield, chemical constituents and the activity of antioxidant enzymes in wheat plants subjected to drought stress conditions. Wheat plants of cv. Giza 168 were subjected to well-watered conditions and drought stress conditions (75% and 50% of field capacity) with and without (0.5 μM EBL + 100 μM Spm) foliar application at 45 and 75 days after sowing during two successive seasons 2013/2014 and 2014/2015. Drought stress significantly reduced relative water content (RWC), membrane stability index, concentration of total chlorophylls, total crude protein, growth, and yield of wheat plants, particularly under 50% of field capacity. However, foliar application (0.5 μM EBL + 100 μM Spm) significantly improved the above parameters in drought stressed wheat plants. Moreover, drought stress significantly increased lipid peroxidation, electrolyte leakage, and concentration of total sugars, total free amino acids, glycinebetaine and proline in wheat plants. However, lipid peroxidation and electrolyte leakage were significantly decreased in stressed plants treated with foliar application, meanwhile, concentration of total sugars, total free amino acids, glycinebetaine and proline were significantly increased. The activity of antioxidant enzymes; superoxide dismutase, catalase, ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase and glutathione reductase, were slightly increased in response to drought treatments, while they significantly increased in response to foliar application in drought stressed wheat plants. The obtained results in this study confirmed the effective influences of 24-epibrassinolide (EBL) and spermine (Spm) for improving drought tolerance of wheat plant by increasing osmopotectants and enhancing ROS scavenging antioxidant defense machinery which resposible for protecting cell enzymes, organelles and cell membranes.

El-Khayat H.M. and Abdellwahd S.M.

ABSTRACT The present study was conducted during 2016/2017 and 2017/2018 on seven years Valencia orange trees in a private orchard in Nubaria, Behera governorate, Egypt to evaluate the effect of magnetically treated irrigation water (MTW) and well water either alone or with adding humic acid, calcium silicate and microorganisms on the leaf mineral, carbohydrate and proline contents, vegetative growth, yield and fruit quality .The results indicated that using magnetized water and all other treatments gave a significant increase in the studied growth parameters as well as tree yield and fruit quality. The magnetized water plus magnetite treatment increased leaf phosphorus and iron. Trees treated with magnetized water plus humic acid had the highest new shoot numbers, TSS, TSS/acidity content and juice weight, as well as the lowest peel thickness. Magnetized water plus calcium silicate gave the highest leaf area, tree yield, fruit diameter, fruit firmness and leaf silicon content. Magnetized water plus Microorganism consists of mixture of yeast - photosynthetic and lactic bacteria and sterptomycetes (EM) treatment caused the most height of tree, Canopy circumference, trunk circumference, and leaf nitrogen and zinc. Mgnetized water plus calcium silicate and magnetized water plus EM treatments showed the highest leaf carbohydrate and fruit vitamin C content. Magnetized water plus humic acid and magnetized water plus EM treatments gave the highest leaf potassium. Fruit weight was highest by magnetized water plus humic acid and magnetized water plus magnetite. It has been concluded that use of magnetized water technique with humic acid, silicon and EM applications would be an economically and safe alternative tool to solve the problem of irrigating with saline water and to enhance orange tree growth and productivity grown under similar conditions of the present study.

Effect of plant growth promoting rhizobacteria on inducing salt tolerance in sunflower (Helianthus annus L) plants

Essam Hoballah, Taghreed E. Eissa and Magdy A. Barsoom

ABSTRACT: To improve the growth, flowering of sunflower plants (Helianthus annus L) cv. "Suntastic" under saline conditions this study was conducted at the Experimental Farm of Ornamental Plant Research Department, Horticulture Research Institute, Giza, Egypt in March of the two seasons, 2017-2018 and 2018/2019, by using three isolates (Azospirillum brasilense, Bacillus megatherium and Pseudomonas fluorescence) applied separately under different salinity (NaCl) levels (0.00, 3000, 4000 and 5000 ppm). Under a randomized complete block design, the obtained results concluded that plant growth promoting rhizobacteria (PGPR) give successful vegetative growth with good flowering characters and induced salt tolerance in (Helianthus annus L.) plants. So, bacterial isolate Bacillus megatherium conformed better vegetative growth and flowering as compared to isolates of Pseudomonas fluorescence and Azospirillum brasilense. The performance of mixture treatment was below as compared to separate inoculation of PGPR isolates. The decrease in growth at higher levels of salinity caused both hyperionic and hyperosmotic stressed, and can lead to plant demise. From the obtained results it could be recommended to use Bacillus megatherium for inducing salt tolerance in sunflower (Helianthus annus L) cv. "Suntastic" under high salinity levels and give successful vegetative growth with good flowering

AbdElghany S.H., Shereen A.H. Saad, A. A. Arafat and Shaban Kh

ABSTRACT: A field experiment was conducted in the farm of Sahl El-Hussinia Agricultural Research Station, El-Sharkia Governorate, Egypt during 2016/2017 and 2017/2018 winter seasons. The impact of potassium humate at different rates (0, 2, 4 and 6 g/L) and irrigation water at different periods 10, 15, and 20 days applied during growth period was studied on some physical and chemical soil properties and Carrot (Daucus carota L.) productivity under saline soil conditions. The obtained results stated that soil pH changed to slightly or moderately alkaline conditions ranged between 8.27 and 8.05. Soil salinity (ECdSm-1) values tended to decrease by increasing potassium humate applied and decreasing the irrigation period, the study showed that 10 days irrigation period gave the highest effects on soil salinity than other periods tested. Also, it emphasized that irrigation water periods and increasing of potassium humate applied significantly increased availability of some macro and micronutrients represented by N, P, K, Fe, Mn and Zn contents in soil after harvest of carrot. This increase led to increase these nutrients in leaves and roots of carrot plants beside weight of fresh roots and the total yield (ton/fed). The study implies application of potassium humate at 6g/l and 10 days irrigation period was the best treatment over the two seasons.

Effect of Foliar Applications of Anti-Heat Stress Treatments on Yield and Fruit Quality of Balady Mandarin and their Effect on Yoghurt

Manal A. Zaky and Meranda A. Tawfek

ABSTRACT Heat stress caused during high temperature and direct solar radiation. Subsequently, sunburn occurred and caused allot of problems, which lead to significant economic losses in Balady mandarin crop. Trees were treated with Kaolin 3% twice, and kaolin 6% to study the effect of kaolin as an antiheat stress on fruit quality of Balady mandarin trees during the two seasons (2016 and 2017). These treatments caused an increase in fruit production as well as fruit quality (weight, volume, diameter, and length). Also treatments caused enhancement in the chemical composition of mandarin fruits, expressed as total sugar, acidity, fibers, protein, TSS/TA ratio and TSS%. Moreover, fruits juice from treated trees were used for preparing mandarin flavored yoghurt. The results showed that kaolin treatments improved the rheological characteristics and the total acceptability of yoghurt. From the obtained results, it is recommended to: carry out foliar application of Balady mandarin, cultivated in newly reclaimed lands with Kaolin at 6% concentration at mid-June to significantly increase fruits quality and the ability to produce mandarin flavored yoghurt, consequently increase the add value to the fruits.

Identification of the physio-chemical processes controlling the composition of groundwater at Wadi El Tumilat area, East Nile Delta, Egypt

Eslam R. Soliman, Reda G.M. Ibrahim, Eglal R. Souaya, Yousra H. Kotp and Khairia A. Gindy

ABSTRACT: Wadi El Tumilat is located to the northeast of Cairo and to the west of Ismailia City. The Quaternary deposits represent the main water-bearing formation at depths range from 5 to 70 m. The aquifer matrix is built up from fluviatile and fluviomarine graded sand and gravel with clay intercalations of limited extension. It rests directly with unconformity surface on the Miocene hard limestone. This aquifer is recharged mainly from surface water system especially Ismailia and El Manaief canals and to less extent from the upward leakage from the Miocene aquifer at the southern part of the study area. The connection between the two aquifers is highly controlled by the presence of deep-seated faults. The groundwater extracted from the Quaternary aquifer is mainly fresh to brackish (TDS= 194.7 to 4916.4 mg/l), while only 10% of samples are saline (TDS=5380 to 6407.6 mg/l). The main objective of the present study is to delineate the main hydrogeochemical and hydrological processes affecting groundwater quality using the conventional geochemical tools and multivariate statistical techniques. Box plots are also used to show the content and distribution of major constituents in the investigated groundwater. The ionic ratios and statistical analyses showed that ion exchange (mainly of reverse type), silicate weathering, evaporation and mixing with surface water and/or Miocene groundwater are the main dominant processes controlling the groundwater quality of the Quaternary aquifer at Wadi El Tumilat area. Future study of the hydrogeochemistry of this aquifer will consider the quantitative assessment of the prevailing hydrogeochemical processes especially evaporation and mixing using appropriate geochemical modeling technique.

Nahed M.M. Atta, Azza A.A. Ahmed, Al-Okaby M.F. Enam and Sh. A. Mohamed.

ABSTRACT: This study was carried out in olive farm in Wadi El Natroun, El-Beheira Governorate, Egypt, to study the effect of deficit rate in different amount of irrigation water, 96, 64 and 32 liter water / tree per hr. (at rates 80, 53.4 and 26.6 %, respectively) are given to olive tree (Dolce var.) and 120 L. water/ tree per hr. (at rate 100%) as a control on the chemical composition and promological parameter (fruit characteristics) i.e. fruit weight, pulp weight, stone weight, pulp stone ratio, fruit length, width, fruit shaper ratio and 100-fruit weight of fresh and processed (pickled) olive fruits, and also on the organolyptic test of processed olive fruit and physo-chemical characteristics of brine throughout the process time (1, 2, 3 and 4 months) i.e. free acidity, combined acidity and pH. These
results of this study revealed that, all parameters of fruit characteristics were decreased with decreasing amount of irrigation water, and they have decreased by pickling process. Processed olive fruits obtained from treatment 96 L. water/tree recorded the highest scores in odor, color, test and texture compared with processed olive obtained from other treatments. Higher content of oil in fresh fruits was found by reducing amount of irrigation water and by pickling process, and vice-versa for total protein. Total polyphenols and reducing sugar recorded higher increased by decreasing amount of irrigation water, but they have decreased after olive process.

Effect of Drying Methods on Edible Film Properties

Marwa M. Helmy, Omar S. Younes and Manal A. Sorour

ABSTRACT: Two different methods of drying (electric dryer and solar energy dryer) were used to dry edible films prepared from CMC with the addition of thyme oil. Different samples of edible films were characterized by measuring thickness, water vapor and gas permeability, water solubility, mechanical properties and transparency. The results indicated that time of drying by solar energy decreased by 70-72% with respect to electric dryer. However, the addition of oil increased time of drying for both methods (electric dryer and solar drying). Different properties of edible films dried using electric dryer and solar dryer were measured, the results observed that solar drying has an effect on O2 CO2, water vapor permeability, transmittance rate and tensile strength. The higher tensile strength was observed for control sample 2% CMC (48.676 N) dried using solar dryer, on the other hand, CO2 and water vapor permeability for edible film samples dried using solar dryer increased with respect to electric dryer and vice versa oxygen permeability. Edible film dried using solar dryer has better transmittance rate than samples dried using electric dryer.

Antioxidant activity and Anti-Inflammatory Effects of Lemon grass on L-Arginine- Induced Acute Pancreatitis in Rats

Hanaa S.M. Abd El-Rahman

ABSTRACT: The present study aimed to evaluate the protective effect of lemon grass aqueous extracts on Larginine- induced acute pancreatitis in rats regarding biomarkers and morphologic changes. This experimental study was performed on Fifty-four male albino rats were divided into nine equal groups. Negative control group received normal saline. Groups 2 and 3 animals were orally administered with aqueous extract of lemon grass 400 and 600 mg/Kg/day. While the pancreatitis was induced in the remain groups by L-arginine (2.5 g/kg, 2 i.p. 1hr interval), group 4 served as positive. Groups 5, 6, and 7 were treated with L-arginine + aqueous extract of lemon grass at doses of 400, 600, and 800 mg/Kg/day,p.o, respectively. Group 8 was received L-arginine + L-carnitine (drug) 500 mg/kg/twice a day p.o. Group 9 was given L-arginine + L-carnitine+ aqueous extract of lemon grass 400 mg/Kg/day, p.o. Rats were sacrificed after 15 days and biochemical, hematological, and histopathological examination were assessed. Evaluation of pancreatic superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) were carried out. The results revealed that, treatment with lemon grass aqueous extract significantly reduced serum amylase and lipase levels, as well as tumor necrosis factor-α (TNF-a) and interleukin-1 B (IL-1B)cytokines. Administration of lemon grass doses dependently ameliorated alters of aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, creatinine, nitric oxide, and histoarchitectural changes in pancrease tissues. A similar pattern for oxidative stress markers was noticed. Both pancreatic MDA and serum nitric oxide levels were declined by increasing the dosages, on contrary the pancreatic SOD and CAT elevated. Lemon grass markedly decreases the biochemical and histopathologic changes during the early stages of acute pancreatitis, thus preserving the pancreas histologically. This study concluded that using lemon grass as a tea beverage important in acute pancreatitis.
