Abstract: A field experiment wasconducted at Research farm, Ambikapur during the kharif season of 2018-19 to study the various integrated nutrient management practices on production and profitability of maize. The experiment was conducted in randomized block designandreplicated thrice. The eleven nuitrient combinations100% RDF (150:80:60 NPK kg ha-1), 75% RDF, 50% RDF excluding and including FYM and used Azotobacterand legume intercropping in three treatments and compared with state practice.Amongst the various nutrient management practices, the higher grain yield was recorded with application of 100% RDF + FYM 5 t ha-1 (7846.7 kg ha-1) was significantly superior over all other treatments. However, it was on par with 100% RDF + Zn 5 kg ha-1 (7313.3 kg ha-1) and 100% RDF (6717.8 kg ha-1). Stover yield, shelling percentage and harvest index was recorded significantly higher with 100% RDF + FYM 5 t ha-1. Again 100% RDF + FYM 5 t ha-1 was the best treatment with the highest net return (₹ 68814.9) and benefit cost ratio (1.58) found at par with 100% RDF + Zn 5 kg ha-1 (₹ 64138.2 and 1.56, respectively) and 100% RDF (₹ 55957.4 and 1.38, respectively)
