PRE HARVEST YIELD FORECASTING MODELS OF SUGARCANE USING WEATHER INDICES IN WESTERN MAHARASHTRA

S.B. Kharbade, K.V. Kulkarni and V.A. Sthool

Abstract

Forecasting models were developed using twenty seven years (1990-2016) of weather and yield data of sugarcane crop. Models were validated for three years (2013-1015). Good agreements have been realized between Actual and predicted yield with similar trends of deviation at preharvest stage. Deviation of predicted yield was ± 10 - 11% in all studies district and R2 values were 73, 84, 65, 71, 97, 61 and 94 for Solapur, Satara, Ahmednagar, Kolhapur, Nashik, Pune and Sangali districts respectively. Hence, these models can be used for forecasting sugarcane yield in preharvest stage which is very useful to government authorities to plan the sugarcane production more efficiently.
