Abstract

Wheat (Triticum aestivum L.) is considered important cereal crops worldwide, ensuring food security post green revolution. Our study results displayed an elevation of 10.6% in root weight density, 15.0 % of root volume density during flowering stage, respectively. The highly significant values for root weight density, root length density and root bulk density were recorded under nitrogen application of 180 kh ha-1 both at flowering and maturity stage. Moreover, delayed senescence and increase in photosynthetic rate were observed during middle and late stages of flowering enhancing light energy interception and improvement in its utilization. The cultivar Yunhan-20410 exhibited a significant 11.1% increase in leaf area index at flowering stage compared to cultivar Yunhan-618, which displayed an increase of 7.1%. Furthermore, the photochemical efficiency and photochemical quenching of flag leaves were recorded 25-30 days after anthesis whereas, 9.6-11.1% of light energy utilization efficiency was increased. The gene expression of TaTZF1, TaNCY1, TaNCY3 and TaAKaGall in flag leaves of wheat were significantly up-regulated for cultivar Yunhan-20410 under nitrogen (N) treatment compared to no N treatment. The findings of present research suggested that high yield and quality can be achieved at N application of 180 kg ha–1. The following recoomendation can be shared with farming community for improving resource efficiency and crop production.
