Abstract

A trial was conducted at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) to study the impact of integrated nutrient management on growth, yield, quality and soil fertility status in sugarcane-ratoon system, Integrated nutrient management practices involving combinations of inorganics (NPK) + organic sources (FYM, biofertilizers, trash incorporation) were tested along with inorganic fertilizer alone. The experiment was laid out in randomized block design with ten treatments in three replications. Significantly higher cane yield (78.8 and 74.5 t ha^-1) was recorded in T6-FYM/Compost @ 20 t ha^-1 +soil test based recommendation over rest of the treatments except T5 FYM/Compost @ 20 t ha^-1 + 100% RDF and T10- RDF+ S+ Zn in both plant and ratoon crops, respectively. The cane yield in T6 was increased by 15.4% in planted cane and 13.7 % in ratoon crop against the treatment in which NPK was applied alone in both the crops. Similarly, CCS yield and sucrose % was also statistically at par in these treatments. Organic carbon %, available N, P and K was significantly higher in T6 and T5 over rest of the treatments in plant and ratoon crops.
