Farmers frequently rely on mineral fertilizers to increase yields, improve or sustain crop productivity, and mitigate the adverse impacts of environmental stresses, including salinity. However, improper fertilization—whether inadequate excessive—can hinder plant growth, reduce nutritional quality, contribute soil degradation pollution. Understanding how different levels nitrogen (N) abiotic stresses such as salt impact yields end-use quality is important maintain food production ensure fair value. In this study, we examined four types spring wheat investigate role adequate N in tolerance their effects quality. The findings revealed no uniform response either low treatment regarding growth grain characteristics. All aspects, biomass reduction, yield variations, components protein content, starch, fiber, were influenced by across various backgrounds tested. some cases, these additive, further reducing value specific genetic backgrounds, while, others, minor. We identified varieties that are relatively tolerant lower levels, maintaining both production, well less sensitive salt, allowing them production. This deeper understanding can now be leveraged breed for improved stress entire life cycle, enhancing under suboptimal conditions minimizing reduced inputs tolerance.

The usage of microbes and biochar (BC) is fundamental in decreasing the impacts salinity stress by promoting plant growth development. purpose this study was to determine impact phosphate solubilizing bacteria (PSB) phosphorous (P)-enriched BC on biochemical characteristics for three lines sunflower ( Helianthus annuus L.) saline soils. designed with at 100 mM NaCl PSB Bacillus subtilis ) 10 9 CFU 1500 Kg ha -1 including RGK38 (salt-sensitive), BGK35 (salt-moderately sensitive), BGK259 (salt-tolerant) based completely randomized block design (CRBD) five replicates. Salinity considerably reduced grain yield, thousand weight (TGW), oil content, chlorophyll (Chl) relative water content (RWC), K, P, while enhancing malondialdehyde (MDA), electrolyte leakage (EL), Na + , Cl - all high rate RGK38. use integrated contributed increases yield. In exposed salinity, PSB+BC raised yield (16%), (27%), RWC (14%), Chl a b (24%), K (22%), P (127%), but lowered MDA (26%), (36%), (41%). Heat map analysis revealed that stood out significantly from other two maximum variability under treatments. showed most among as an indicator identifying susceptibility PSB, BC. This has encouraging implications agricultural operations stress-affected areas highlighting potential combining environmentally acceptable sustainable ways increase resilience salty
