Instability Analysis of Agricultural Productivity: A District Level Assessment in Karnataka State in India

The study has examined productivity instability of major crops for 20 years by considering first period as 1998-99 to 2008-09 and second period as 2009-10 to 2018-19 at the district level in Karnataka state. 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.
