Abstract
The efficacy of organic sources, viz. farmyard manure (FYM) and green Karanj leaf (Derris indica) manure (KL), in combination with inorganic sources of nutrients in rice wheat cropping system was evaluated and the results revealed that substitution of 25% N through Karanj leaf in rice followed by 100% recommended dose of fertilizer in wheat produced significantly maximum rice equivalent yield (94.72 q ha-1), production efficiency (39.32 kg grain ha-1 day-1), apparent N recovery (59.90%) and benefit cost ratio (2.85:1) and was at par with 25% N substitution by Karanj leaf in rice followed by 75% recommended dose of fertilizer in wheat and 25% N substitution by farmyard manure in rice followed by 100% recommended dose of fertilizer in wheat, while, maximum land use efficiency (65.94%) was under 50% N substitution by Karanj leaf in rice followed by 100% recommended dose of fertilizer in wheat and maximum N-use efficiency was recorded under 25% N substitution by Karanj leaf in rice followed by 75% recommended dose of fertilizer in wheat.
