Abstract A field experiment was conducted to Develop nutrient management practices for organic maize production under irrigated condition was carried out at Agricultural Research Station, Kathalagere Davanagere dist, during kharif 2009 in clay loam soils with medium NPK content. There were ten treatments laid out in Randomized Complete Block Design with three replications using DEKALB-DK984 hybrid maize. Grain yield and stover yield significantly higher (49.0 q ha-1 and 8.5 t ha-1 respectively), with application of FYM at 12.5 t ha-1and cattle urine at 34300 l ha-1 which was on par with the application of FYM 12.5 t ha-1 and cattle urine at 29400 l ha-1 (45.7 q ha-1 and 8.3 t ha-1 respectively) and with recommended dose of fertilizers (150:75:50 kg NPK ha-1 along with FYM at 10 t ha-1). Higher grain and stover yield was attributed to the improments in the growth components viz. plant height, number of green leaves, leaf area, total dry weight. Higher NPK uptake was recorded with the application of FYM at 12.5 t ha-1and cattle urine at 34300 l ha-1 (161.5, 32.2 and 145.5 kg ha-1 respectively) which was on par with the application of FYM at 12.5 t ha-1+ cattle urine at 29400 l ha-1 and recommended dose of fertilizers (150:75:50 kg NPK ha-1 along with FYM at 10 t ha-1). Application of FYM at 7.5 t ha -1 and cattle urine at 24500 l ha -1 recorded higher available NPK in soil (289.7 kg N ha-1, 30.6 kg P2O5 ha-1, and 210.5 kg K2O ha-1respectively) which was on par with the application of FYM at 12.5 t ha-1+ cattle urine at 29400 l ha-1 and recommended dose of fertilizers (150:75:50 kg NPK ha-1 along with FYM at 10 t ha-1. Higher net returns, gross returns and B:C ratio(Rs.34452, 45952, and 3.0 respectively) were obtained with the application of FYM at 12.5 t ha -1 and cattle urine at 34300 l ha -1.
