Nitrogen fertilization plays a critical role in promoting plant growth, improving physiological and biochemical traits, enhancing wheat productivity. This study aimed to evaluate the effects of seven nitrogen (N) doses—0, 45, 90, 135, 180, 225, 270 kg N ha−1—on performance under semi-arid subtropical conditions over three consecutive growing seasons (2015–2018). A randomized complete block design (RCBD) was used assess comprehensive set agronomic, physiological, biochemical, nutritional parameters. Key factors examined included grain yield, above-ground biomass, harvest index, total content grains straw, traits such as photosynthetic rate, stomatal conductance, transpiration accumulation soluble proteins, sugars, amino acids. The also incorporated multivariate statistical techniques, multi-trait genotype–ideotype distance index (MGIDI), principal component analysis (PCA), descriptive statistics identify most effective dose. Results indicated that 180 ha−1 (T4) treatment for efficiency, with 135 (T3) showing favorable outcomes. In contrast, higher doses (225 ha−1) led diminished performance, suggesting threshold beyond which becomes counterproductive. These findings support optimal dose maximizing yield quality while contributing more sustainable profitable production.
