EFFECT OF VARIETIES AND INTEGRATED NUTRIENT MANAGEMENT ON PRODUCTIVITY AND PROFITABILITY OF SORGHUM (SORGHUM BICOLOR)Rajat Malik, Abhinandan Singh, Diksha and Aakash MalikAbstract To study the effect of varieties and integrated nutrient management on yield attributes, yield and economics of sorghum (Sorghum bicolor) under sub-tropical condition of Madhya Pradesh an field experiment was conducted at the Crop Research Centre of School of Agriculture, ITM University, Gwalior, (M.P.) during the kharif season of 2022 .The experiment was conducted by taking four levels of fertilizers viz. T1 -Control, T2 - 100% RDF, T3 -75% RDF + 25% Vermicompost, T3 - 50% RDF + 50% Vermicompost and three varieties (V1 =Mahalakshmi-296, V2 =Amarnath-2000 V3= Western jowar in factorial randomized block design which were replicated thrice. The fertilizers were applied as per the requirement of the treatments. The experimental study revealed that among the phosphorus levels, the application of 75% RDF + 25% Vermicompost recorded significantly highest yield attributes and seed yield. However, among the varieties, application of Mahalakshmi-296 resulted in highest yield attributes and yield of Sorghum. Among the economic analysis, application of 75% RDF + 25% Vermicompost and combined treatment of Mahalakshmi-296 incurred the highest cost of cultivation, highest gross return, net return and Benefit cost ratio. Therefore, for Sorghum cultivation, 75% RDF + 25% Vermicompost and combine treatment of Mahalakshmi-296 was proved to be profitable. |
