Type: article
Abstract: The field investigation was carried out at Department of Agronomy farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2019-20. The experiment was laid out in randomized block design with three replications and seven different nitrogen levels treatment with an objective to study the growth and yield of cotton as influenced by various levels of nitrogen under rainfed condition. Treatments consisted of different nutrient management practices including FYM and nitrogen doses viz., Absolute Control (N1), FYM @ 5 t ha-1 (N2), N2 + 30 kg N ha-1 (N3), N2 + 60 kg N ha-1 (N4), N2 + 90 kg N ha-1 (N5), N2 +120 kg N ha-1 (N6) and N2 + 150 kg N ha-1 (N7). Cotton crop was sawn on 29th June 2019 while it was harvested in four pickings. The result revealed that a significant differences in plant height, leaf area, number of sympodial branches and dry matter accumulation and until harvest. Growth attributes viz., plant height and numbers of sympodial branches were maximum in treatment of FYM @ 5 t ha-1+150 kg N ha-1. However, leaf area and dry matter accumulation were maximum with treatment of FYM @ 5 t ha-1+120 kg N ha-1.
