Developed a mobile app for estimating fertilizer requirements to achieve planned yield targets in sugarcane cultivation. The app works on the basis of targeted yield equations for both plant and ratoon crop. Soil test results (N, P, K) and FYM data have to be filled for estimating fertilizers. Based on these data, the app calculates the utilization of N, P, K using appropriate factor components and also estimates the amount of Urea, DAP and MOP. This app is available for sugarcane cultivation in
