To reduce the environmental pollution, this study was designed to test the effect of using compost and biostimulants as total or partial replacement for mineral nitrogen on productivity and grain quality of two wheat cultivars. Two field experiments were conducted in the Desert Experimental Station, Cairo University located at Wadi El-Natroon, Egypt during two successive seasons (2016/2017 and 2017/2018). A split-split-plot design in a randomized complete block arrangement was used. Four fertilizer treatments (100% mineral nitrogen as control, 100% compost, 75% compost + 25% mineral nitrogen and 50% compost + 50% mineral nitrogen). Four levels of biostimulants foliar applications (control, 0.75 L ha−1, 1.13 L ha−1 and 1.5 L ha−1). Treatments were tested on two wheat cultivars (Egyptian cultivar, Gemmiza-10 and Nigerian cultivar, LacriWhit-4). Results indicated that, the treatment of 50% compost + 50% mineral nitrogen fertilizer along with 1.5 L ha−1 of biostimulants (VIUSID® agro) significantly increased the grain yield of both wheat cultivars, LacriWhit-4 and Gemmiza-10 (4.44- and 4.53-ton ha−1, respectively). The increase of grain yield was 0.9- and 1.36-ton ha−1, respectively. The treatment of 100% compost significantly increased protein, crude fiber, total sugars, Mg and Mn contents in grain while the treatment of 100% mineral nitrogen fertilizer significantly increased ash, total phenols, P and Ca contents in grain. Replacing nitrogen fertilization with compost significantly increased ether extract and carbohydrates content of the Nigerian cultivar grains while N, K and Fe contents were increased in the grains of both tested cultivars. The foliar application of biostimulants (VIUSID® agro) at different levels significantly increased protein, carbohydrates, total sugars, P, K, Ca, Cu and Zn contents. It can be concluded that replacing mineral nitrogen fertilizer with a combination of compost and mineral nitrogen (50% compost + 50% mineral nitrogen) along with 1.5 L ha−1 of biostimulants (VIUSID® agro) is recommended for the enhancement of productivity and grain quality of wheat while reducing environmental pollution.

A combination of abiotic stresses in sandy soils, such as saline water, saline soil, and lack of nutrients, affects productivity of faba bean. In this study, organic amendments and biostimulants (VIUSID ® agro) were used in combination to increase yield of faba bean seed as well as the protein content under a sandy soil and irrigation affected by salt water. Two field experiments were carried out during two successive winter seasons of 2016/2017 and 2017/2018. A split-split-plot design in a randomized complete block was used. The main plots were allotted to the organic amendments, rates of biostimulants (VIUSID ® agro) were assigned to sub-plot, and the cultivars were applied to sub-sub-plot. The results showed that the treatment of plant compost applied as an organic amendment and 1.5 L ha -1 of biostimulants (VIUSID ® agro) with foliar application significantly increased seed yield of cultivars, Sakha-4, Sakha-1, and Giza-843 by 17.2, 33.0, and 19.8 % respectively, compared to control under a sandy soil and irrigation water affected by salts. The interaction between Sakha-1 cultivar, plant compost, and 1.5 L ha -1 of biostimulants (VIUSID ® agro) achieved the optimal combination, providing the highest grain yield, as compared to all other treatments. The combination of these treatments is recommended in order to improve faba bean productivity under similar conditions.

The recent study’s objective was to detect variability in Egyptian multi-cut barseem genotypes via studying ten different commercial varieties regarding forage yield production during two successive winter seasons (2018/19 and 2019/20). These varieties, namely; Hartuor, Narmar, Sinai 2, Giza 6, Helaly, Gemiza, Serw1, Sakha 4, Khadrawy and Meskawi. Four cuttings were taken in each season. The analysis of variance in each season revealed that the mean squares due to berseem genotypes were significant for all studied traits. A wide range of variation was observed for plant height traits). Berseem varieties had fresh seasonal yield ranging from 114.70 to 137.72 and averaging 125.20 ton acre-1 in the first season. In the second season, the genotypes had a mean seasonal new yield of 146.89 with a range of 120.26 to 162.07 ton acre-1. Seasonal forage dry yield of the varieties ranged from 20.72 to 26.53 with a grand mean of 24.31 ton acre-1 in the first season, and it went from 25.10 to 29.84 with a great standard of 28.65 ton acre-1 in the 2nd season. Based on per se performance, the variety Khadrawy was identified for total fresh and dry forage yields. The values of PCV for different characters were higher than corresponding GCV values. Estimates of heritability were high for plant height at 3rd cut in the two seasons, plant height at the 1st and 2nd cuts, and seasonal dry yield in the second season. High heritability values coupled with high genetic advance were recorded for plant height at 2nd and 3rd cut in the two seasons, at 4th cut in the first season, and 1st cut in the second season. Genetic advance as percent of the mean (GAM) was found to be the highest for plant height at 1st cut in the second season (21.78 %) followed by seasonal dry yield in 2nd season (16.07 %).

Background and Objective: Faba bean (Vicia faba L.) is one of the most important food legumes in Egypt. The acreageʼs and seed yields vary from one season and location to another. This study aimed to investigate the effect of calcium sulphate application and humic acid on the growth, yield and yield components of faba bean under sandy soil conditions. Materials and Methods: Two field experiments were carried out to study the effect of calcium sulphate (gypsum) rates (0, 0.75 and1.5 t fedG 1 ), foliar spraying with three levels of humic acid (0, 1.5 and 3 g LG 1 ) and their interactions on yield and yield components of three cultivars of faba bean (Giza-843, Sakha-1 and Sakha-4). Results: The differences between the two calcium sulphate rates for agronomic traits and seed chemical composition were significant in the two seasons. Application of 1.5 ton CaSo 4 fedG 1 gave the utmost values for most attributes studied traits in both seasons. Also, results showed that the differences between humic substance concentrations for all studied traits were significant in both seasons except HI. Foliar faba bean plants with 3 g LG 1 humic acid fadG 1 gave the highest values for all studied traits in the two seasons. Also, results showed that the differences between cultivars for all studied traits were significant in both seasons. G-843 faba bean cultivar gave the highest values for all studied traits within the two seasons. Conclusion: The most favourable effects for growth parameters and chemical composition traits resulted in the highest levels of CaSo 4 or humic acid for the Giza-843 cultivar.
