The current study was performed at the Research Farm of Faculty of Agriculture, New Valley University during 2017/2018 and 2018/2019 seasons in order to evaluate response of onion cv. Giza 6 to some organic fertilizers, i.e., cattle manure and poultry manure in addition to mineral fertilizers as control treatment. The results obtained showed that the vegetative growth characters and yield components of onion plants were significantly influenced by fertilizers kinds. Combination of poultry manure at 75% of recommended fertilizers and 25% of mineral fertilizers recorded the highest values for both vegetative growth characters and yield components, i.e., plant height, leaves number, plant fresh and dry weight, crop growth rate, bulb fresh weight, bulb diameter, bulb dry matter, marketable yield and total yield in a comparison to mineral fertilizers (control) in both seasons. While, the content of chlorophyll a, b, total carotenoids, N, P and K in onion leaves and vitamin C, sulfur volatile oil and TSS in onion bulb were increased significantly by application of poultry manure at 25% of recommended fertilizers plus 75% of mineral fertilizers compared to mineral fertilizers (control) in both seasons. It can be concluded that application of poultry manure at 75% of recommended fertilizers plus 25% of mineral fertilizers increased growth , yield and improved bulb quality of onion plants cv. Giza 6 under the New Valley Governorate conditions

The current study was conducted to evaluate the effect of foliar application of salicylic acid treatments on growth, yield and quality of lettuce plants cv “Big Bell” that grown under water deficit stress. A field experiment was carried out during 2018-2019 and 2019-2020 seasons at the Experimental Farm, Faculty of Agriculture, Cairo University, Egypt. Drought was induced by withholding watering for 15 days after salicylic acid (SA) application exactly at 20 and 30 days after trasplanting. Five treatments were utilized. These were water-stressed +100 ppm of SA, water-stressed +200 ppm of SA, water-stressed +300 ppm of SA foliar spray, water-stressed only, and the fifth group served as control. Results indicated that water stress adversely affected growth and productivity parameters of lettuce cultivar “Big Bell”. Water stressed plants at earlier stage of growth (20 day stage) were more inhibitory as compared with the plants at the age of 30. Generally, foliar spraying with salicylic acid significantly protected against the stress and increased root length, root weight, fresh head weight, head diameter, photosynthetic pigments compared to treatment that under water deficit. However, proline content increased under drought as well as under SA treatments. Spraying of salicylic acid at 200 ppm at the age of 30 was the most effective treatment that causing significant increase in yield by18.31% and 26.9% relative to control treatment in the first and second seasons, respectively. Application with salicylic acid increases drought tolerance and avoids the deleterious effect of water stress.

A field experiment was carried out during the two successive seasons of 2017/18 and 2018/19. The aims of the experiment were to investigate the effect of different planting arrangement patterns: T1 (3 pea: 1 lettuce), T2 (2 pea: 1 lettuce), T3 (1 pea:1 lettuce), T4 (side pea: side lettuce) in addition to sole lettuce and sole pea (control) treatments regarding the growth, yield, and nutritional quality, along with the financial aspects of applying intercropping systems for lettuce and pea productivity. The obtained results revealed that, intercropping lettuce with pea was more effective than planting pea crop alone, as it increased the lettuce yield by 12.2%-37.7% and 27.7%- 60 % in the first and second seasons respectively according to the intercropping system applied. All intercropping treatments except for T4 (side pea: side lettuce) treatment reduced the pea yield. The highest pea yields were produced by both sole pea andT4 treatments, while the lowest pea yield was form T3, in both seasons. T3 treatment depressed pea pod yield to 60% of its mono-cropped yield. On the other hand, T1 and T2 treatments produced the highest yield for lettuce in both seasons. Intercropping lettuce with pea, led to an improvement in the protein percentage in pea. LER of pea/lettuce intercropping treatments were more than unit. Moreover, the highest values for both LER and MAI obtained fromT1 treatment. Calculated “aggressiveness” suggested that all secondary crop treatments were more dominant than pea in all intercropping treatments. The intercropping system of 3pea:1 lettuce could be a gainful system to obtain the greatest efficiency of land

The study was conducted to investigate the influence of seaweed extract, chelated manganese, and two other chemical substances that are known as Agro promotor1(substance No.48) and Agro promotor2 (substance No.50) on the growth, yield, and quality of cauliflower. Results revealed that yield and its components increased with using each seaweed extract(3ml/l), chelated manganese (12%) at a concentration of 0.25g/l, and Agro promotor1 (substance No.48) at a concentration of 3 ml/l compared with control (untreated) treatment. Using both seaweed and chelated manganese treatments exceeded other foliar spraying treatments and caused a significant increase in fresh weight of the whole plant, leaves fresh weight,leaves dry weight percent, yield, TSS and vitamin C. The increase in total yield ranged from 12.8-48.2% by using the previous treatments as compared with control. Also, foliar sprays of seaweed extracts led to the earliness in cauliflower production as compared with the control. This study recommends using seaweed extract at a concentration of 3ml/l or chelated manganese (12%) at a concentration of (0.25g/l) for cauliflower production. Agro promotor1 (substance No.48) at a concentration of 3 ml/l can be applied in case of unavailability of seaweed extract or chelated manganese (12%).

A field experiment was conducted to evaluate the response of okra sowing date and variety on growth and yield at the Experimental Farm of Faculty of Agriculture, Assiut University, Assiut, Egypt, during 2011 and 2012seasons. Two sowing dates i.e. April 15 and May 15 and five varieties i.e. BaladyAssiut, BaladyQena, Emerald, Golden Coast and PusaSawani were studied. From the results it was noticed that the fruit number and fruit yield significantly affected by sowing date and variety. In case of sowing on 15thApril, the heighest fruits yield was (8.577 and 8.146 ton/feddan) in both seasons. However 15th May sowing date produced the lowest fruits yield (4.227 and 4.005ton/ feddan). PusaSawani cv produced the highest yield of okra in two sowing dates (12.341, 6.632 and 11.904, 6.365 ton/feddan) in both seasons, respectively. Determination of optimum sowing date is considered an important to have optimum yields. Results shown that varities, Golden Coast and PusaSawani produced higher fruits yield on 15th May than BaladyQena cv sown on 15th April. The interaction between varieties and sowing date was significant in both seasons for plant height, number and weight of green pods/plant and total green yield/fed.

In this study, Novozym 435-catalyzed interesterification of ethyl ferulate (EF) with phosphatidylcholine (PC) in a two-phase system consisting of an ionic liquid (IL) and toluene was optimized to prepare feruloylated lysophospholipids (FLPs). Optimum conditions for the interesterification process were found to be [Bmim][Tf2N]/toluene ratio of 1: 1 (v/v), solvent volume of 4 mL, molecular sieves (4 Å) concentration of 80 mg/mL, reaction temperature of 55℃, substrate molar ratio of 5: 1 (PC/EF), Novozym 435 concentration of 50 mg/mL. Under these conditions, two FLPs products (1-FLP and 2-FLP) with total conversion rate of 50.79% were obtained. Because the formation of 1-FLP was significantly higher than 2-FLP, 1-FLP was purified and characterized by LC-MS and NMR. In addition, 1-FLP showed DPPH scavenging activity comparable with those of EF and BHT. Therefore, this study provides a good method for transformation of ferulic acid to improve its solubility and promote its application as functional ingredient in the food and pharmaceutical industries.

The climate changes, soil fertility decline, water scarcity, and desertification are expected to generate a great threat to crop production and food security worldwide. Additionally, more food is needed to meet the demand of the world’s growing population. Therefore, scientists are searching for innovative strategies to reduce food loss and enhance food security. Utilization of food processing by-products as food or food ingredients is one of the proposed strategies that can contribute to food security. Rice is a major food crop worldwide and there is a great amount of rice bran is produced as a byproduct of rice milling. Bran constitutes about 10% of the rough rice grain and it is rich in nutrients and bioactive compounds. Rice bran protein (RBP) has shown good nutritional and biological values. Therefore, many studies have been carried out to investigate the suitability of RBP for the application in preparing nutritional and healthy foods. Also, hydrolysates and peptides with various biological activities were isolated from RBP and identified. Therefore, this article aimed to review the research advances in extraction, potential health benefits, and food applications of RBP and its derived hydrolysates. Challenges facing the application of RBP in the food industry are also discussed.

To evaluate the impact of male-female cohabitation period on the fertility, hatchability, injuries response, and some hormonal estimates in Japanese quails. A total of 288 mature Japanese quails were equally divided into 3 groups (3 groups × 8 replicates × 12 birds), with 1 Male: 2 Females sex ratio. In the first group (control), male and female quails were reared continuously together, while the males in the second and third groups were reared together with females once or twice/wk times (24 h/ time), respectively throughout the experiment. The obtained results showed that final body weight (FBW/g), fertility (%), and hatchability (%) in the second and third groups significantly (P ≤ 0.01) increased compared with the control group. Laying quails in the second and third groups significantly (P ≤ 0.01) produced more and heavier eggs, while the feed consumption and feed conversion ratio were significantly (P ≤ 0.01 …
