Changes in organic carbon, available N, P and K under integrated use of organic manure, green manure and fertilizer on sustaining productivity of pearl millet-pigeonpea system and fertility of an inceptisol

Abstract: A field experiment was conducted to study the effect of inorganic fertilizers coupled with organic manure and green manure on organic carbon, available N, P and K in Inceptisol. The pearl millet-pigeonpea cropping system significantly improved the organic carbon content and available N, P and K status of the soil. The highest grain and stover yield of pearl millet was obtained with organic source of nutrients to meet 50 per cent N in conjunction with 50 per cent RDF over control. Nitrogen applied in two splits recorded the highest grain yield (1767 kg ha−1) followed by FYM to meet 50 per cent N with 50 per cent RDF (1744 kg ha−1). Similarly grain yield of pigeonpea recorded the highest grain yield (801 kg ha−1) with 50 per cent N through subabul with 50 per cent RDF. The organic carbon content, available N, P and K were significantly influenced by the use of 50 per cent N through organic manure in conjunction with 50 per cent RDF under pearl millet-pigeonpea cropping system in Inceptisol
