Abstract: Maize (Zea mays L.) is a revolutionary and exciting crop that makes a significant contribution to world agriculture and, more specifically, almost 2000 million metric tons of food supplies around in the world. The present investigation entitled “Effect of integrated nutrient management on growth and yield of hybrid maize (Zea mays L.), with different spacing in Vertisol of Chhattisgarh Plain” was carried out at Instructional Farm, DKS College of Agriculture and Research Station, Bhatapara during Kharif season of 2019-20, with the objective to study the effect of different spacing and integrated nutrient management on growth and yield of hybrid maize. Experiment was laid out in Split-Plot-Design (SPD) with three replications and eighteen treatment combination. Hybrid maize was sown on 14th July, 2019 in a split plot design with spacing as main plot and nutrient combinations in sub plot. There were three levels of spacing (cm) viz. S1-60×15, S2-60×20 and S3-60×30 and six level of nutrient combination viz. N1: Control treatment, N2: RDF (150 N kg/ha, 80 P2O5 kg/ha, 60 K2O kg/ha), N3: 75% RDF + VC 1 t/ha + seed treatment with Azotobactor + PSB culture, N4: 75% RDF + FYM 6 t/ha + seed treatment with Azotobactor + PSB culture, N5: 50% RDF + VC 2 t/ha + seed treatment with Azotobactor + PSB culture, N6: 50% RDF + FYM 12 t/ha + seed treatment with Azotobactor + PSB culture.
