Fungicide Application Affects Nitrogen Utilization Efficiency, Grain Yield, and Quality of Winter Wheat

Nitrogen (N) is a vital component of crop production. Wheat yield varies significantly under different soil available N. Knowing how wheat responds to or interacts with N produce grains essential in the selection use efficient cultivars. We assessed this study variations among genotypes for productivity-related traits three cropping systems (CS), high-nitrogen fungicide (HN-WF), without (HN-NF) and low-nitrogen (LN-NF) 2015, 2016 2017 seasons. ANOVA results showed genotypes, CS, their interactions affected agronomic traits. Grain (GY) increased higher leaf chlorophyll content, importantly CS supply. Yellow rust disease reduced GY by 20% 28% 2015 2016, respectively. Moreover, averaged over growing seasons, was 23.78% supply, while it greatly increased, 52.84%, both application, indicating synergistic effect on GY. Fungicide supply improved ability accumulate during grain filling, hence protein content. Recently released cultivars outperformed older ones most including Genotype performance stability analysis production differences levels CS. The nitrogen recently across found suggest that resource efficiency can be via cultivar targeted
