“…Therefore, as the human population increase, wheat production will need to increase. Increasing wheat production requires introducing resilient genotypes (genetic improvement) and improving growth conditions (the crop environment) (Elbasyoni et al, 2019; Morsy et al, 2021; Serres et al, 2019). Moreover, increasing wheat production without genetic improvements would increasingly pressure land use and other resources, that is freshwater, energy and fertilizers, which are already limited, particularly in the arid and semi‐arid regions (Kanianska, 2016).…”

In arid and semi‐arid regions, soil salinity and sodicity are the most common constraints to agriculture production, in particular in North Africa. The effect of gypsum application has been widely studied in saline‐sodic soils. However, the gypsum amendment's influence on the performance, productivity and mineral absorption of salt‐sensitive and tolerant wheat cultivars in both saline‐sodic and normal soils under field conditions has not yet been investigated. A two‐season (2016–17 and 2017–18) field experiment was undertaken to investigate the impact of gypsum on wheat growth, yield and minerals uptake for salt‐tolerant and sensitive cultivars grown in normal (EC = 1.3 dS m−1, pH = 8.4 and ESP = 7.1–8.0%) and saline‐sodic soils (EC = 5.8–6.2 dS m−1, pH = 8.8 and ESP = 19.3–22.4%) in the western Nile delta, Egypt. The gypsum requirement was applied to decrease the initial ESP from 19.3–22.4 to 10.0% was calculated for 0.3 m soil depth. Gypsum application (6.0 and 4.7 ton ha1, for the first and second season, respectively) reduced soil pH, EC and ESP of saline‐sodic soil by 31.6, 7.3 and 39.0%, respectively (two‐season mean). Furthermore, gypsum application increased Ca2+, Mg2+ and K+ in the flag leaf by 54.7, 24.5 and 45.7%, respectively (2‐season mean) under saline‐sodic soil. While, in the normal soil, gypsum application increased Ca2+, Mg2+ and K+ by 67.3, 32.7 and 78.7%, respectively. In contrast, gypsum applications decreased Na+ and Cl− content by 17.2 and 15.0% and by 40.0 and 35.5%, respectively, in the saline‐sodic and normal soil, respectively. Under saline‐sodic and normal soils, gypsum application significantly increased the K/Na ratio by 90.0 and 175.2%, respectively (2‐season mean). Interestingly, across cultivars, gypsum amendment increased grain yield by 20.7% (6.9 to 8.3 t ha−1) for normal soil and by 8.0% (5.8 to 6.3 t ha−1) for saline‐sodic soil. The positive impact of gypsum was more pronounced under the normal soil and for the salt‐sensitive cultivars than in saline‐sodic soil and for salt‐tolerant cultivars. Growers can cultivate salt‐tolerant cultivars and use gypsum as a precaution to reduce saline‐sodicity build‐up and to increase nutrient absorption.

“…Reduced PH could be one of the plant mechanisms to minimize water stress by reducing transpiration (Acosta‐Motos et al., 2017). Furthermore, wheat growers in several regions globally, including Egypt, prefer to grow tall wheat (Abdelmageed et al., 2019; Elbasyoni et al., 2019) because the straw can be as valuable as the grain. Thus, plant breeders tend to maintain tall wheat plants under abiotic stress conditions while improving other traits such as GY and rust diseases resistance to avoid releasing short plants that are difficult to harvest under these drought conditions or produce less straw (Gao et al., 2020).…”

“…Across the environments, the preceding crop was corn (Zea mays L.), and the residue was incorporated into the soil. The soil's physical and chemical characteristics and agronomic practices, including weed control, recommended phosphorus, and potassium applications, were previously reported (Elbasyoni et al, 2019). Throughout the three seasons, plants were not subjected to water deficit; hence supplementary irrigation was applied based on the volumetric soil water content.…”

The University of Nebraska has bred some of the most winter hardy wheat (Triticum aestivum L.) cultivars in the United States. With the advent of a new race of stem rust in Africa, the breeding program identified a testing site in northern Egypt, a Mediterranean environment, for seedling disease resistance screening. Quite surprisingly, the Nebraska winter wheat lines flowered when grown in northern Egypt, indicating the lines were vernalized. To confirm this result, a panel of 112 Nebraska winter wheat genotypes and three commercially grown Egyptian spring wheat check cultivars were grown in three replicates in a randomized incomplete block design at two locations for 3 years (2016/2017-2018/2019) in Egypt. Seven traits were measured on all genotypes (the number of days to flowering; total chlorophyll content; plant height; leaf, stem, and stripe rust reaction; and grain yield). The winter wheat genotypes flowered and several of them were not significantly different in grain yield from the spring cultivars. A multi-trait stability index identified 22 genotypes (20% selection intensity, the local checks, and 19 lines from the United States) for good performance. This study provides novel evidence that winter wheat can flower in northern Egypt, can be used for adult plant resistance screening, and provide a grain yield comparable to the commercially grown spring wheat cultivars. Our findings are expected to facilitate future efforts to hybridize winter-by-spring lines to develop new genotypes with ANOVA, analysis of variance; BLUP, best linear unbiased prediction; CIMMYT, International Maize and Wheat Improvement Center; GEI, genotype by environment interaction; GY, grain yield; LR, leaf rust; ME, mega-environment; MET, multi-environment trial; MTSI, multi-trait stability index; NDF, number of days to flowering; PCA, principal component analysis; PH, plant height; SPAD, soil plant analysis development; SR, stem rust; WAAS, weighted average absolute score; YR, yellow rust.

“…Of all the cereals, rice and wheat cropping systems have the lowest levels of nitrogen use efficiency (NUE), less than 30-40% (Norton et al, 2015;Taulemesse et al, 2015;Herrera et al, 2016). An additional amount of N fertilizer is applied to compensate for the effect of a lower uptake rate and to achieve higher grain yield (Elbasyoni et al, 2019). Reproductive stage N remobilization (NR) from the storage pool to sink organs is an important determinant for grain N recovery at harvest (Gaju et al, 2011).…”

Nitrogen (N) is an important macronutrient needed for grain yield, grain N and grain protein content in rice. Grain yield and quality are significantly determined by N availability. In this study, to understand the mechanisms associated with reproductive stage N remobilization and N partitioning to grain 2 years of field experiments were conducted with 30 diverse rice genotypes during 2019-Kharif and 2020-Kharif seasons. The experiments were conducted with two different N treatments; N deficient (N0-no external N application, available soil N; 2019-234.15 kgha-1, 2020-225.79 kgha-1) and N sufficient (N120-120 kgha-1 external N application, available soil N; 2019-363.77 kgha-1, 2020-367.95 kgha-1). N application increased the NDVI value, biomass accumulation, grain yield, harvest index and grain N accumulation. Post-anthesis N uptake and N remobilization from vegetative tissues to grain are critical for grain yield and N harvest index. Rice genotypes, Kalinga-1, BAM-4234, IR-8384-B-B102-3, Sahbhagi Dhan, BVD-109 and Nerica-L-42 showed a higher rate of N remobilization under N sufficient conditions. But, under N deficiency, rice genotypes-83929-B-B-291-3-1-1, BVD-109, IR-8384-B-B102-3 and BAM-4234 performed well showing higher N remobilization efficiency. The total amount of N remobilization was recorded to be high in the N120 treatment. The harvest index was higher in N120 during both the cropping seasons. RANBIR BASMATI, BAM-832, APO, BAM-247, IR-64, Vandana, and Nerica-L-44 were more efficient in N grain production efficiency under N deficient conditions. From this study, it is evident that higher grain N accumulation is not always associated with higher yield. IR-83929-B-B-291-3-1-1, Kalinga-1, APO, Pusa Basmati-1, and Nerica-L-44 performed well for different N use efficiency component traits under both N deficient (N0) and N sufficient (N120) conditions. Identifying genotypes/donors for N use efficiency-component traits is crucial in improving the fertilizer N recovery rate and site specific N management.
