Abstract:
Integrated use of plant nutrients aim at combined use of inorganic and organic sources of plant nutrients to improve efficiency of applied nutrients, reduce environmental hazards and improve crop productivity. A field experiment was conducted at the Research Farm of Soil Science and SWC, Arid Agriculture University, Rawalpindi, Pakistan. It was laid out according to RCBD in split-plots with three replications. The sub-plot size was 6 m x 4 m (24 m2). The wheat-maize cropping system was used to record data of two summer maize crops in under rainfed environment. There were nine treatments of integrated plant nutrient management practices. These included: control (without NPK fertilizer, FYM or biofertilizer); half of recommended NPK; full dose of recommended N-P2O5-K2O (120-90-60 kg/ha); FYM @ 20 t/ha, FYM on N requirement basis + make-up dose of P/K fertilizer; ½ NPK + FYM @ 10 t/ha; ½ NPK + Biopower; ½ FYM + Biopower and ½ NPK + ½ FYM + Biopower. The significant increase in various yield attributes due to IPNM produced highest biological and grain yield of 8579 kg/ha and 3128 kg/ha in 2005; while these were recorded 8475 kg/ha and 3119 kg/ha respectively in 2006. Integrated plant nutrient treatments especially with Biopower improved NPK uptake over sole mineral/organic fertilizers. The economic analysis revealed that wheat-maize cropping system was profitable with integrated use of mineral, organic and/or biofertilizer Biopower under rainfed condition.
