Abstract
An experiment was conducted on “Performance of Kharif maize (Zea mays L.) with integrated nutrient application” during Kharif 2017, on Soil Conservation and Water Management Farm, CSA University of Agriculture and Technology, Kanpur on hybrid Maize with three level of inorganic fertilizers (kg/ha) i.e.100% R.D.F. (100 N + 60 P + 40 K+ 20 Z), 75% RDF (75+45+30+15), & 50% RDF (50+30+20+10) along with three Levels of organic manure viz; 15, 20 & 25 ton FYM/ha. On the basis of overall results it can be concluded that the fertility level 75% RDF + 25 t FYM/ha (F2+O3) was found superior over all other treatment combinations of fertility management maximum yield of grain (26.47 q/ha), stover (89.01 q/ha) and water use efficiency is 9.76 kg ha-1 mm-1. The treatment combination F2+O3 (75% RDF + 25 t FYM/ha) is very suitable among over all treatments.
