Abstract:
The present investigation entitled “Effects of Different Nitrogen Levels on Growth And Yield Of Wheat (Triticum aestivum L)” was conducted during the year 2021-2022 at the Research farm of Agronomy, Dev Bhoomi Uttarakhand University, Manduwala, Dehradun (UK). The experiment consisted of eight treatments T1: control, T2: 25 Kg N+RDF-P&K, T3: 50 Kg N+RDF-P&K, T4: 75 Kg N+RDF-P&K, T5: 100 Kg N+RDF-P&K, T6: 125 Kg N+RDF-P&K, T7: 150 Kg N+RDF-P&K, T8: 175 Kg N+RDF-P&K. The study revealed that, among the treatments,T6 (125 Kg N+RDF-P&K) recorded highest plant height at 30, 60, 90 and harvest (21.82cm, 41.65cm, 71.89cm, 93.56cm), total dry matter per plant at 30, 60, 90 and harvest (18.22g, 30.64g, 64.01g, 100.33g), Leaf are index at 30, 60, 90 and harvest (1.21dm², 3.29dm², 4.55dm² and 4.41dm²) respectively, number of seeds per straw yield (58.367q ha¹), grain yield (5576.0 kg ha¹, biological yield (14728kg ha¹), harvest index (37.85%), cost of cultivation (18,800.33 Rs ha¹), total gross returns (62,908.33 Rs ha¹), net returns ((44108.33 Rs ha¹) and benefit cost ratio (3.34) compared to control. In the present study, it can be concluded that the T6 is the best treatment for wheat variety on basis of Growth and yield.
