Abstract

The optimization of fertilization techniques allows for the attainment of a high-quality and high-yield crop, resulting in economic gains and mitigating any environmental risks. The regulation of nitrogen (N) and sulphur (S) is of paramount importance in wheat cultivation, as both macronutrients play a critical role. Both factors have a substantial influence on the enhancement of growth and yield characteristics. Furthermore, the elements S and N are also crucial in facilitating the augmentation of seed protein levels. Nevertheless, the current requirement is to determine the most suitable application rate in order to attain the highest possible wheat output. Hence, the present study was designed to investigate the effects of varying application rates of S and N on wheat. The experimental design consists of ten treatments, namely: control (no nitrogen (0N) + no sulphur (0S)), 40 kg ha-1N (40 N + 0 S), 80 kg ha-1 N (80 N + 0 S), 120 kg ha-1 N (120 N + 0 S), 40 kg N ha-1 + 15 S, 80 kg N ha-1 + 15 S, 120 kg N ha-1 + 15 S, 40 kg N ha-1 N + 30 S, 80 kg N ha-1 + 30 S, and 120 kg N ha-1 + 30 S. Each treatment is replicated three times. The findings of the study indicated that the inclusion of 120 kg N ha-1 + 30 S resulted in considerable enhancements in many plant characteristics, including plant height (5.77 ± 0.39a), number of tillers (9.67 ± 0.47a), fresh weight (54.80 ± 1.55a), grains per spike (34.00 ± 0.82a), number of spikes (5.77 ± 0.39a), and 1000 grain weight (44.97 ± 0.57a). The efficacy of 120 kg N ha-1 + 30 S in improving grain N content (2.95 ± 0.06a), N uptake (86.37 ± 1.07a), and protein content (18.44 ± 0.36a) in wheat was confirmed, highlighting its large impact compared to the absence of N and S fertilization. In summary, the treatment involving the application of 120N + 30S demonstrates superior efficacy in promoting the attainment of optimal wheat production. It is recommended that further investigations be conducted to examine the effects of varying soil textures and meteorological circumstances on wheat growth and yield enhancement. These investigations should be carried out in diverse geographical regions, in order to determine whether this specific amendment is the most effective for promoting wheat growth and improving output.
