Abstract Plant breeders have to employ strategies and techniques produce new improved wheat cultivars increase productivity meet the needs of growing population. Therefore, they develop a cultivar for adaptation environment management practices. One most important criteria plant should focus on is exploitation genotype × interaction (GEI). Thus, this study aimed assess variability 24 genotypes in different seasons by using R software “Metan Package”. Moreover, estimates stability parameters finally highlights winning across seasons. Field experiments were conducted three consecutive specifically 2019/2020, 2020/2021 2021/2022 at locations. The assessment was done traits such as height [cm], flag leaf area [cm 2 ], chlorophyll index [SPAD], spike number [spike/m fertility ratio [%], grain [grain/spike], weight [g], yield [kg/ha]. Results indicated performances certain environments well included study. Winner G-20, G-10, G-30, G-4, IRAQ selected according their high potential. It can be concluded that use Multi-Environment Trail Analysis-METAN package powerful detecting promising with stable yields under various climate change conditions.

Water resource shortage and unreasonable application of nitrogen (N) fertilizer have been problems in wheat production northern China. However, the interaction effects water regimes N practices on root growth, grain yield, soil water, inorganic changes as well water-N use efficiency are still unclear under drip irrigation. A field experiment was conducted during 2020–2021 2021–2022 winter (Triticum aestivum) growing seasons. In this study, three irrigation schedules (i.e., applied up to 80% [D1], 75% [D2], 70% [D3] soon content decreased 65%, 60% or 55% capacity) two at base, jointing, booting stages were 90, 72, 48 kg ha−1 [N1], booting, filling 40, 40 [N2], respectively) considered. The decease amount offset by increase consumption. addition, significantly interacted with NO3−–N accumulation (2021–2022), NH4+–N accumulation, SPAD value (2020–2021), stems grains maturity, average length weight density flowering stage. Irrigation, rather than practices, affected total uptake, crop transformations (NT), contribution NT (NTPC), productivity, which, for these seasons, D2 increased uptake 18.1% (p < 0.05), 39.4% 0.05) N1 compared D3. Additionally, highest WUE ANUE found 2021–2022.

Wheat (Triticum aestivum L.) yields may be reduced by projected rainfall decline due to climate change as well environmental protection demands for less nitrogen (N) fertilizer inputs. Therefore, our study aims determine how decreases in and the reduction of N inputs might impact production different wheat genotypes. A field experiment was carried out a warm-summer humid continental Switzerland with two water treatments: rainfed rainout shelters reduce during grain filling. This overlaid treatments (non-fertilized enough supply reach 180 kg ha−1), four winter genotypes, three pre-crops (barley, Hordeum vulgare L.; oilseed rape, Brassica napus pea, Pisum sativum across seasons. Grain yield protein content, related components, water-soluble carbohydrates (WSC), use efficiency (NUE) associated traits, were among assessed variables. Additionally, soil mineral (Nmin) measured at beginning tillering. The seasons encompassed both average above precipitation. shelter extended range low filling, compared last 30 years. filling had no on yield, regardless crop season, application, pre-crop, initial Nmin, or genotype. applications when fields an Nmin > 50 ha−1, nor after poor establishment caused wet autumn.
