Abstract
A field study was carried out at Kanpur, Uttar Pradesh during 1999–2000 and 2000–2001 to evaluate the efficacy of organic sources, viz. farmyard manure (FYM), wheat (Triticum aestivum L. emend. Fiori & Paol.) straw and green leaf manure (GLM) in organic, inorganic combinations in rice (Oryza sativa L)-wheat cropping system. Rice yield was maximum with 25% N substitution through green leaf manure (GLM) and wheat yield was higher with 50% substitution of N through GLM in rice + 100% NPK fertilizer in wheat. However, 100% NPK fertilizers in both crops yielded at par with best treatments in both rice and wheat for different parameters. The NPK uptake in rice and wheat was higher with 100% NPK to both crops and in the treatments with 50 or 25% NPK substitution through GLM in rice and 100 or 75% NPK through fertilizers in wheat. The application of 100% inorganic NPK to both crops earned maximum net profit of Rs 20,202/ha from rice-wheat system. This treatment also maintained maximum values of organic carbon, available P and available K in residual soil.
