An experiment entitled “Effect of methods of crop establishment and nitrogen levels on growth and yield of rice (Oryza sativa L.)’’a field experiment was conducted Kharif season-2023 at the Agronomy Research Farm of Shardhya Bhagwati Singh Agriculture Research Farm, Chandra Bhanu Gupta Krishi Mahavidyalaya, B.K.T. Lucknow (Uttar Pradesh). The experiment was laid out in split plot design with three replications. The treatment consisted of three methods of crop establishment (M1-Random transplanting conventional (30 days old seedling), M2-Transplanting (20 x 10 cm)-21 days old seedling and M3- SRI (25 x 25 cm)-12 days old seedling were kept in main plots and four nitrogen levels (N0- 0 kg N ha-1, N1- 60 kg N ha-1,N2-120 kg N ha-1, and N3-180 kg Nha-1) in sub plots with three replications. The experimental site was silty loam having medium organic carbon (0.45%) and available nitrogen (376.0 kg/ha.), phosphorous (25.54 kg/ha.) and potassium (165.84 kg/ha.). All the growth parameters, development studies, yield attributes and yield of rice were significantly higher under SRI method as compared to other methods of crop establishment. Among nitrogen levels all growth parameters, development studies, yield attributes and yield of rice were significantly higher under 180 kg N ha-1 being statistically at par with 120 kg N ha-1 and found to be significantly superior over other nitrogen levels. Test weight (1000-grain weight) did not influence significantly due to methods of crop establishment and nitrogen levels. The nitrogen, phosphorus and potash content (%), and its uptake (kg ha-1) in grain and straw were obtained higher under SRI method with combination 180 kg N ha-1 however, it was being at par with 120 kg N ha-1 and found to be significantly superior over other nitrogen levels. The Protein content (%), and protein yield (kg ha-1) in grain and straw were obtained higher under SRI method with combination 180 kg N ha-1 however, it was being at par with 120 kg N ha-1 and found to be significantly superior over other nitrogen levels. The maximum net return (Rs. 106168.88) and B:C ratio (2.05) was obtained under SRI with application of 180 kg N ha-1 (M3N3). Therefore, this combination was proved to be more remunerative than other treatment combinations.
