Instability categories were grouped as low < 15%, medium 15-30% ,High >30%. A low value index indicates the high stability in crop productivity. Through Cudde Della Valle index it was observed that, instability has been low and declined over the time in Rice, Maize, Sugarcane while medium instability noticed in Ragi, and cotton .The trend of instability is high in Arhar, Gram, Groundnut and Jowar. Instability in Pulses and oil seeds is high because area under these crops have been shifted towards Rice, maize which are giving high remunerative prices and assured profit.
