Sugarcane is an exhaustive crop and is known to remove large quantities of nutrients from the soil specially the macronutrients such as N, P, K, Ca and Mg. It was reported in the literature that a 100 tons of cane stalks remove from the soil 80 kg N, 40 kg P2O5, 140 kg K2O and 3 kg Ca (Fauctioner, 1991). Therefore, sufficient amount of fertilizer should be given to the soil with proper nutrient management. Accordingly, the ongoing research plan is addressing the issue of updating and optimization of fertilization and cultural practices through handling of the following topics:
• monitoring of soil fertility so as to guide fertilizer application in sugarcane.
•Intensive studies on variety differential response to fertilizer.
•Updating of fertilizer recommendations.
•Testing of new compound fertilizers to boost cane yield based on balanced nutrient approach.
•Soil and plant analysis using highly advanced equipments for N, P and trace elements and also to develop standard testing techniques and criteria to guide future nutrient application.
•Improving and conserving soil physical and chemical properties for optimal plant growth.
•Introducing cost effective husbandry practices.
