ABSTRACT=Sugarcane is a long-duration and nutrient exhaustive crop. To improve the nutrient use Sugarcane is a long-duration and nutrient exhaustive crop. To improve the nutrient use Sugarcane is a long-duration and nutrient exhaustive crop. To improve the nutrient use Sugarcane is a long-duration and nutrient exhaustive crop. To improve the nutrient use efficiency, 4-R nutrient stewardship approach comprising applying nutrient at right time and place, with right method, and proportion. Improper nutrient management in such nutrient-exhaustive crop will result in various nutrient losses and environmental pollution.Concerning this, a field study was performed on calcareous soils of lower Indo-Gangetic plains of India during two subsequent years at Sugarcane Research Institute, RPCAU, India, to soil thereby facilitating the higher NPK uptake by the plants and ratoon both comparing 2 split applications of N and no splitting of K. From this study, it was observed that the band placement coupled with 7 splitting of N and K is the best fertilizer application protocol ensuring higher growth, yield, quality, and nutrient uptake of sugarcane in the calcareous soils of Indo-Gangetic plains.
