The treatment consisted of substitution of 25% of N by FYM and composted sulphitation press mud cake (CSPM) along with 50, 75 and 100% NPK and bio-fertilizer in plant, while 100 NPK and trash and biofertilizer in ratoon. The result indicated that cane yield with application of 25% N through FYM or CSPM along with 50 and 75% NPK and bio-fertilizer was found at par with 100% NPK, while ratoon yield was on par with addition of sugarcane trash and bio-fertilizer over 100% NPK which indicated substitution of 25% N with organic manures in sugarcane plant-ratoon system. The uptake of N, P and K followed the similar trend of cane yield, while juice quality remained unaffected. The addition of organic manures along with fertilizers showed residual build up in organic carbon and available N, P₂O₅ and K₂O content of post-harvest soil. 收起
