Abstract
A field experiment was conducted at Raipur, in wheat crop grown after rice, application of 50% of the recommended N through organic sources i.e. FYM, rice straw and green manure to rice and 50% through chemical fertilizer or even with 100% of recommended NPK fertilizer to rice and wheat significantly produced the plant height, number of tillers per square meter, plant population per square meter, number of spikelet's per spike, test weight, elongate the growth span and increased the grain and straw yield and simultaneously nutrient uptake of wheat crop. When 75% NPK + 25% N applied through organic sources to rice and 75% recommended dose of NPK fertilizer to wheat, significantly increased the aforesaid yield components, yield and nutrient uptake respectively, over no NPK fertilizer. The application of 50% recommended NPK fertilizer to rice and wheat had no significant effect on yield components, yield and nutrient uptake of wheat. Higher response was observed where integration of recommended fertilizer dose with organic source was done in preceding rice crop.
