Abstract

The performance under graded levels of fertilizers and in combination with green leaf manure (GLM) and Farmyard manure (FYM) was studied with rice hybrids ADTRH-1 in a rice-rice cropping sequence. It was observed that 125% recommended dose of fertilizer (100:50:50 NPK) +6.25 t GLM gave the highest grain yield (5.67 and 5.96 t ha−1), highest nutrient uptake and return per rupee invested (2.10 and 2.20), the yield advantage being 52 per cent compared RDF (100:50:50 NPK).
