Abstract
A field experiment was conducted during kharif season of 2021-22 at Agricultural Research Station, Tandur, Vikarabad, Professor Jayashankar Telangana State Agricultural University (PJTSAU) under deep black soils to study the effect of integrated nutrient management on the growth and yield of kharif redgram (Cajanus cajan L.). The experiment was laid out in Randomized block design with 9 treatments in 3 replications. Treatments comprised of T1: Control, T2: 50% RDF (10:25:0 NPK kg ha-1) + 50% FYM (2.5 t ha-1), T3: 75% RDF (15:37.5:0 NPK kg ha-1) + 25% FYM (1.25 t ha-1), T4: 100% RDF (20:50:0 NPK kg ha-1), T5: 50% RDF + FYM @ 5 t ha-1 + Rhizobium (Seed treatment) + PSB (Seed treatment), T6: 75% RDF + FYM @ 5 t ha-1 + Rhizobium (Seed treatment) + PSB (Seed treatment), T7: 100% RDF + FYM @ 5 t ha-1 + Rhizobium (Seed treatment) + PSB (Seed treatment), T8: 100% RDF + Rhizobium (Seed treatment) + PSB (Seed treatment) and T9: FYM @ 5 t ha-1 + Rhizobium (Seed treatment) + PSB (Seed treatment). Among the treatments, application of 100% RDF, FYM @ 5 t ha-1, Rhizobium and PSB recorded significantly higher seed yield (1898 kg ha-1) and stalk yield (6275 kg ha-1).
