Abstract: An investigation was conducted during 2022-23 and 2023-24 at the Research Farm, Raj Mohini Devi College of Agriculture and Research Station, Ambikapur, Chhattisgarh to examine the growth performance of maize in response to varied residue and nutrient management options.Experiment was laid out in strip plot design with three replications. The treatment consisted of twelve treatment combinations including four vertical factors i.e., M1– Residue removal, M2– Residue incorporation, M3– Residue incorporation + spray of microbial consortium on residue and M4– Zero-tillage + residue retention and spray of microbial consortium on residue and three horizontal factors i.e., N1– 100%RDF of NPK (120:60:40 kg N:P2O5:K2O ha-1), N2– 100% RDN and P and 50% RDK and N3– 75 % RDF of NPK + 5 t FYM ha-1. Results revealed that adoption of crop residue incorporation + spray of microbial consortium recorded significantly higher plant population, growth parameters of maize viz., plant height, number of leaves plant-1, leaf area plant-1, leaf area index, fresh weight and dry matter accumulation which was at par to residue incorporation and zero-tillage + residue retention and spray of microbial consortium. Similarly, significantly more plant population and growth parameters were recorded under 100% RDF as compared to others.
