A study was conducted to estimate the Production performances and acreage response of cotton in Dharwad district of Karnataka. The Compound growth rate were employed to estimate the trend and it was found that area under cotton decreased but production increased due to increase in productivity in Karnataka. In district, area under cotton was decreased due to subdivision of district but production was also decreased because of high production cost and non-availability of sufficient quantity of farm inputs. The cotton productivity in the district is higher than the state productivity this is mainly due to good rainfall and good management practices. Acreage response was estimated using Nerlovian lag adjustment model and it was found that the cotton acreage was positively influenced by lagged acreage followed by lagged price and lagged yield. The coefficient of adjustment for the district and the state was 0.55 and 0.46 implying farmers of district took 1.82 years and state farmers took 2.84 years in making adjustments in allocating the area under cotton. Long Run Elasticity with respect to price was higher than Short Run Elasticity which indicated that the acreage under cotton in the district was more elastic in long run than short run period.
