Abstract
A long term experiment was conducted on integrated nutrient management in rice-wheat system at Jabalpur (M. P.) since kharif season 1987-88 to evaluate the sustainable productivity of rice on long term basis. The present paper deals with the studies during the years 2002-03 and 2003-04. Integrated use of 50% N through FYM/wheat staw/green leaf manuring with sunnhemp+50% NPK to rice followed by 100% NPK to wheat or 25% N through FYM/wheat straw/green manuring with sunnhemp+75% NPK to rice followed by 75% NPK to wheat was comparable to application of 100% NPK to both the crops in terms of different growth parameters, yield attributes, productivity, nutrient uptake and economics of rice.
