In a long-term rice-wheat system, application of 100% recommended NPK dose through fertilizers + additional 50% N through FYM in rice significantly increased milled, head rice recovery and length breadth ratio (19.7, 59.5, 27.2%) over control (no fertilizer, no manure). It had significantly higher rice grain bulk density than 50, 75 and 100% recommended NPK dose through fertilizers. Application of 75% recommended NPK dose through fertilizers + 25% N through FYM had significantly higher (9.9%) hectoliter weight of rice than control. In wheat, 100% recommended NPK dose through fertilizers had significantly higher hectoliter weight, dry and wet gluten percentage and protein content, sedimentation value and ß-carotene over control. Supplementation of chemical fertilizers with FYM improved quality parameters in both rice and wheat crops than application of chemical fertilizers alone.
