Three field experiments were carried out during 2022 summer season at three diverse locations of Gemmeiza, Sakha and Mallawy Experimental Stations of Agricultural Research Center (ARC), Egypt. Thirty crosses (ten inbred lines crossed with three testers inbred line Sd. 7, Sk. 5 and SC 130) and four standard checks SC 10, SC 2031, TWC 321 and TWC 324 were evaluated for yield and yield related traits to evaluate using line × tester mating design. Analysis of variance revealed significant differences among genotypes for most traits indicating existence of variability among genotypes. Results showed that maternal parents play the most important role. The general combining ability effect showed that Gm. 1031, Gm.62 and Sk.5 are good combiners for earliest, shortened and lower ear placement. Four inbred lines (Gm. 267, Gm. 50, Gm.66 and Gm. 64) and testers Sk.5 were good general combiner for grain yield. The crosses (Gm. 62×Sc. 130), (Gm. 66× Sk.5) and (Gm. 64×sd. 7) had significant values of SCA for plant and ear height and the cross (Gm. 52 × SC. 130) had significant values of SCA for grain yield. Most of all crosses had better performance than check varieties for earliness, short plant and lower ear placement. The two crosses (Gm. 64×Sk.5) and (Gm. 64×SC. 130) were better than all check varieties for grain yield. For grain yield, the cross (Gm. 66×Sd. 7) had a significant superiority percentage over check (SC 2031) while the two crosses (Gm. 52×SC. 130) and (Gm. 64 × SC.130) had significant superiority percentages over checks (TWC321 and TWC324). Therefore, Identify superior crosses to improve the yielding ability in maize breeding programs.

Dual-purpose cereals culturally provide the opportunity to graze a crop during the vegetative phase, and still harvest grain yield at the end of the growing season. It can also help to face climatic changes like frost or dry conditions risk. The aim of the study was to determine the benefits of a dual-purpose barley culture in relation to livestock feed, human nutrition, risk mitigation, and whether a malting variety can also be used for dual-purpose use. A field experiment was carried out in the farm of Nubaria Agricultural Research Station, El-Behera Governorate, Egypt, using five barley varieties during the two successive growing seasons of 2019/2020 - 2020/2021 for dual purpose utilization. No significant differences between the two seasons. The cutting treatment revealed significant or highly significant differences on all studied traits except number of tillers.m -2 and number of spikes.m -2 . Green forage weight was highly significantly affected. Concerning normal cultivation, the differences among the five barley cultivars were highly significant for all studied traits except number of spikes m -2 . Significant or highly significant differences were found among studied traits concerning cultivars and cutting treatment interaction. Normal cultivation conditions also exhibited that Giza 132 gave the highest grain yield followed by Giza133 and Giza 126. While Giza 2000 gave the heaviest green forage weight followed by Giza 133 and Giza 126 under dual purpose utilization. Moreover, under dual purpose utilization, Giza 126 and Giza 2000 were the best barley cultivars for both green forage and grain yield production. The existing improved dual barley variety conserve the purpose in specified environment as alternative for the green forage demand without sacrificing the grain yield in the rainfed, arid, and semi-arid regions of Egypt

This investigation was carried out in three winter seasons 2019/20, 2020/21 and 2021/2022at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt to estimate some genetic parameters of yield and its components as well as the extent of heterosis, inbreeding depression, heritability, genetic advance, and behavior of gene action in three faba bean crosses. The analysis of gene effects was done using means of Six populations (P 1 , P 2 , F 1 , F 2 , Bc 1 and Bc 2 ) of three faba bean crosses were used in this study. These crosses were (Sakha 3 x R V 322), (Nubaria 1 x RV 322) and (Giza 429 x Marina). Analysis of variance showed significant differences among the generations for all traits. Scaling test showed that most studied characters were significant, indicating the presence of non-allelic interactions. Both dominance and additive gene effects were important but mostly dominance higher than additive ones, indicating that dominant genes playing an important role in the inheritance of such traits beside the additive one. The second cross (Nubaria 1 x RV 322) gave a highly significant (aa) with negative values for flowering, maturity, chocolate spot and rust diseases traits, these indicate that the materials used in this study have a decreasing alleles expression which makes it improving through selection in the early generations. Significant positive inbreeding depression and heterotic effect values were detected for most studied traits. Crosses, especially the first cross (Sakha 3 x R V 322) gave the highest heritability in narrow-sense and genetic advance for number of branches, number of pods/plants, number of seeds/pod and seed yield. Therefore, selection in these populations should be effective and satisfactory in the successful breeding purposes.
本研究于2019/20、2020/21和2021/2022三个冬季在埃及Kafr El-Sheikh省Sakha农业研究站进行，对3个蚕豆杂交组合的产量及其组成部分遗传参数、杂种优势程度、近交抑制、遗传力、遗传进步和基因作用行为进行了研究。利用3个蚕豆杂交组合的6个群体(p1、p2、f1、f2、bc1和bc2)进行基因效应分析。这些十字架是(萨哈3 × rv322)，(努巴里亚1 × rv322)和(吉萨429 ×玛丽娜)。方差分析表明，各代间各性状差异显著。标度试验结果表明，大多数研究性状显著，表明存在非等位基因相互作用。显性和加性基因效应都很重要，但多数显性效应高于加性效应，说明除加性基因外，显性基因在这些性状的遗传中起重要作用。2个杂交品种(Nubaria 1 × RV 322)在开花、成熟、巧克力斑病和锈病等性状上呈极显著负相关(aa)，说明本材料等位基因表达量呈下降趋势，可通过早期世代的选择进行改良。大多数性状的近交抑制值和杂种优势效应值均呈显著正相关。杂交，特别是第一次杂交(Sakha 3 × R V 322)在枝数、荚果/株数、种子/荚果数和种子产量方面具有最高的狭义遗传力和遗传进步。因此，在这些群体中进行的选择应该是有效和令人满意的，以达到成功繁殖的目的。

A three-year study was carried out at Giza Agricultural Experiments and Research Station, Faculty of Agriculture, Cairo University, Giza, Egypt during the summer seasons of 2018, 2019, and 2020 to evaluate the effect of low irrigation water levels on the productivity of corn and soybean under different solid and intercropping systems. This study included 18 treatments. Three levels of irrigation water (7140, 5712, and 4284 m 3 /ha) were expressed as 100 "I Sa ", 80 "I Sb " and 60%"I Sc ", respectively. Six cropping systems that included alternating ridges 2:2 (A a ), mixed (B b ), solid corn ridges (Soc a ), solid corn beds (Soc b ), solid soybean ridges (Sos a ), and solid soybean beds (Sos b ). Corn cultivar S.C.132 (white grains) and soybean cultivar Giza 111 were used in this study. A split plot design in randomized complete blocks arrangement with three replications was used. All soybean and corn traits were negatively affected when received I Sc . However, there were no significant differences between I Sa and I Sb for all soybean traits in all seasons. A significantly higher seed yield per hectare for soybean was recorded for solid plantings than for intercropping systems. Intercropping system Bb had high kernel weight and grain yield per hectare. Irrigation water use efficiency (IWUE) was increased by decreasing the applied irrigation water level from 7140 to 4284 m3/ha. The intercropping system Bb recorded high values of IWUE. Land equivalent ratio (LER) was not significantly affected by applied irrigation water levels, while intercropping system Bb recorded high LER in all seasons. Most interactions were significant throughout the seasons of the study. It can be concluded that intercropped soybean cultivar Giza 111 with corn in raised beds that received irrigation water of 5712 m3/ha recorded higher productivity values (IWUE and LER), as well as total and net returns, than the other treatments.

The present study was carried out at Gemmeiza Agricultural Research Station, El-Gharbia Governorate, Egypt, during the three growing seasons of 2019/20, 2020/21, and 2021/22 to determine the genetic variance components and type of gene action controlling yield and its components by using the means of the six populations (P1, P2, F1, F2, BC1, and BC2) of the four barley crosses. The base generation of the four crosses was sown under normal (1636.06 m3 fed -1 ) and water stress conditions (601.06 m3 fed -1 ). Mean effects (m) varied for all attributes in all crosses and were highly significant. Additionally, under both scenarios, the relative significance of additive-dominance effects changed with characters and crosses. Results generally showed that non-allelic interactions existed in all crosses for all the examined characteristics. In most of the examined traits, dominance was stronger than additive and additive dominance among the epistatic components, showing that these traits were significantly influenced by dominance and associated non-allelic interactions. For the majority of the examined qualities under both circumstances, positive heterotic effects compared to the mid parent and better parent were discovered. For the majority of the studied traits, the highest predicted genetic advance values were paired with high and moderate narrow-sense heritability values in all crosses. These findings suggested that early generations could be used for selection to obtain high-yielding genotypes under either normal or stressful conditions. Finally, the most promising crosses were the two crosses 2 and 3 under water stress conditions (601.06 m3fed-1), which had high genetic advances associated with high heritability and would be of interest in breeding programs for improving the most studied traits in barley.

This investigation was carried out in four winter seasons: 2017-– 18 (F 2 ), 2018 – 19 (F 3 ), 2019 – 20 (F 4 ), and 2020 – 21 (F 5 ) at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt, to study the comparison between three breeding methods: pedigree, bulk, and single pod descent for improving seed yield in segregating generations of faba bean crosses: (1) Triple White x Giza 429; (2) Ohishima-Zaira x Giza 429; (3) Giza 40 x Giza 429; and (4) Ohishima-Zaira x Foul Sbai labiade. The pedigree method had a superiority over the other two breeding methods for almost all studied traits in all crosses of the three generations, except for the cross 1 of the F 4 generation and the cross 4 of the F 5 generation, where the bulk method had a superiority. Narrow-sense heritability estimates were moderate in the four studied crosses of the three generations, with few exceptions. Predicted genetic advance estimates were moderate for the number of branches, pods, seeds, and seed yield per plant in all crosses of the three generations. While the same estimate was low for chocolate spot disease, flowering date, plant height and 100-seed weight in approximately all crosses of the three generations. Comparable predicted genetic advances were observed with respect to the two breeding methods for chocolate spot disease in F 3 and F 4 generations. while bulk exceeded that for single pod descent in the F 5 generation. The bulk method had a superiority over single-pod descent in the three generations for the number of pods and seeds per plant. The bulk method exceeded that for single pod descent in the F 5 generation for seed yield per plant. Broad-sense heritability was moderate under bulk as well as single pod descent methods for plant height, number of branches, pods, and seeds per plant, and seed yield per plant. Predicted genetic advance was considered moderate in most cases, except for chocolate spot disease in the cross 3 and 4 of all generations, rust disease in the cross 3 of F 3 and F 4 -generations, and flowering date in all crosses of all generations where the values were considered low.

Phosphogypsum (PG) is considered a by-product from the degeneration of phosphate rock (PR) in sulfuric acid. PG is widely used to improve the physico-chemical properties of soil and increase the amount of soluble nutrients in the soil. The experiment was carried out during the 2021 – 2022 seasons at Sids Research Station, Agricultural Research Center, Bani Sweif, Egypt, using the Giza 95 cultivar to evaluate the effect of PG (1.5 and 2.5 tons/fed) alone or with natural stimulants of farmyard manure (FYM) and phosphate solubilizing bacteria (PSB) on leaves' chemical constituents, growth and yield characteristics, fiber properties, and soil properties after cotton harvesting. The experiment design was a split-plot with three replicates. The main plots included calcium superphosphate and PG applications, and the sub-plots included control, FYM, and PSB applications. The results illustrated that PG application (2.5 tons/fed) recorded the significantly highest values of all studied parameters. Adding FYM achieved the significantly highest results, followed by PSB application compared to control. The interaction between PG application (2.5 ton/fed) and FYM (5 ton/fed) gave the best means on all studied parameters during the two seasons. The positive effect of PG application individually or with FYM and PSB might be related to enhancing soil properties, reducing soil pH, and producing organic and growth hormones, causing an increase in macro-and micro-nutrient uptake by plants and improving cotton plants' growth and development
磷石膏(PG)被认为是磷酸岩(PR)在硫酸中变质的副产物。PG被广泛用于改善土壤的理化性质，增加土壤中可溶性养分的含量。本试验于2021 - 2022年在埃及Bani Sweif农业研究中心Sids研究站进行，以吉萨95棉花品种为研究对象，评估单独施用PG(1.5和2.5吨/饲)或与农家肥(FYM)和磷酸溶菌(PSB)等天然兴奋剂对棉花收获后叶片化学成分、生长和产量特性、纤维特性和土壤特性的影响。试验设计为3个重复的分裂图。主样区包括过磷酸钙和PG，次样区包括对照、FYM和PSB。结果表明，施用PG (2.5 t / d)时各项指标均显著最高。与对照组相比，添加FYM取得了显著的最高结果，其次是PSB应用。在两个季节中，施用PG(2.5吨/日)和施用FYM(5吨/日)的交互作用对所有研究参数的平均值最好。单独施用PG或与FYM和PSB联合施用PG的积极作用可能与改善土壤性质、降低土壤pH、产生有机激素和生长激素有关，引起植物对宏量和微量养分的吸收增加，促进棉花植株的生长发育
