Effect of integrated nutrient management on quality protein maize (zea mays L.)

A field experiment was conducted during kharif season of 2010 at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur to study the integrated nutrient management on quality protein maize (Zea mays L.) cv. HQPM-1. Sixteen treatment combinations comprising four levels of enriched FYM with fertilizers viz., conventional (FYM @ 10 t/ha+100% RDF), enriched FYM+50% RDF, enriched FYM+100% RDF and enriched FYM+150% RDF and four biofertilizer levels viz., control, Azotobacter, PSB and Azotobacter+ PSB were laid out factorial concept in randomized block design with three replications. The application of FYM @ 10 t/ha enriched with 150% RDF recorded significantly increased grain yield (4449.52 kg/ha), stover yield (8026.52 kg/ha), Sharvest index (35.64%) and protein content in grain (11.84%) over rest of the treatments. Similar trend was also observed in N and P content and uptake in grain and stover and available N and P in soil. Seed inoculation with Azotobacter+ PSB culture maximized grain yield (4368.35 kg/ha), stover yield (873.6 kg/ha), harvest index (35.26%) and protein content in grain (12.16%) over another treatment. Similar trend was also observed in N and P content and uptake in grain and stover and available N and P in soil.
