Abstract

A field experiment was conducted during 2003 to 2005 for two plant cane and one ratoon at CSRS, Padegaon to develop an eco-friendly nutrient management strategy for seasonal sugarcane grown on Vertisol with ten treatments. Application of 100 % recommended dose of NPK with 25 % additional N through FYM + biofertilizers and the treatment of application of 75 % RD NPK with 25 % N through FYM were found superior over the other sources and levels in terms of cane (146.0 and 143.5 t ha-1) and CCS yield (20.1 and 19.5 t ha-1) (for plant cane and ratoon crops, respectively) with maintaining soil health and economics. Results clearly indicate the saving of 25 % inorganic fertilizers by use of integration of different nutrient sources with maintaining soil fertility and economics of the sugarcane plant and one ratoon.
