Long term study on different crops indicated that application of balanced NPK fertilizer couldn’t meet higher yield due to poor physical properties and micronutrient deficiencies. Keeping in view to the above concept a experiment entitled “Effect of Integrated Nutrient Management on Growth and Yield of Rabi Sorghum (Sorghum bicolor (L.) Moench)” was conducted at post graduate experimental farm of M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi during the rabi season, 2022. The experimental soil was sandy loam with low in available nitrogen and medium in phosphorus and potassium. The experimental design was randomized block design, which consists of 10 numbers of treatments as different combinations of recommended dose of fertilizer (RDF) and farmyard manure (FYM), each treatment replicated thrice. The treatments are T1: Control, T2: 50% RDF, T3: 75%RDF, T4: 100%RDF, T5: 50%RDF+5t FYM ha-1, T6: 50% RDF + 10t FYM ha-1, T7: 75% RDF + 5t FYM ha-1, T8: 75%RDF+10t FYM ha-1, T9: 100%RDF + 5t FYM ha-1, T10: 100%RDF + 10t FYM ha-1. Among all the treatments significantly highest growth, yield attributes and nutrient uptake were recorded from the treatment 100% RDF + 10t FYM ha-1(T10). Application of 100% RDF + 10t FYM ha-1 recorded highest sorghum grain yield (2416 kg ha-1) and gross return (₹85108/- ha-1). However, maximum net return (₹48010/- ha-1) was recorded from 100%RDF + 5t FYM ha-1 but B:C ratio (1.49) from 75%RDF.
