Integrated nutrient management in rice (Oryza sativa)–sugarcane (Saccharum officinarum) (plant)–sugarcane (ratoon) cropping sequence

Field investigation was carried out at Navsari Agricultural University, Navsari to study the integrated nutrient management in rice (Oryza sativa L.)–sugarcane (Saccharum officinarum L.) (P)–sugarcane (R) cropping sequence during the years 2000 to 2006. For securing higher yield and remuneration in rice - sugarcane (plant)– sugarcane (ratoon) cropping sequence, application of 25% N through FYM + 25% N through poultry manure + 50% N through inorganic fertilizer to the rice–sugarcane (plant)–sugarcane (ratoon) cropping sequence not only gave net return and B:C ratio close to that obtained with application of 100% recommended dose of fertilizer as per soil test value or as per general state recommendation but also improved the soil health in terms of positive nutrient balance.
