The pattern of cropping is a major feature of the agricultural land use in an area. Systematic understanding of cropping pattern changes over the years is very important, for the farmers to get better returns, for the entrepreneurs to decide the optimal locations and capacities of new agro-based plants and factories, for the government and law-makers to check over or under production of farm products, thus ensuring the required overall balance. The present study was undertaken with an objective to study the temporal changes in cropping pattern, cropping intensity and factors determining these changes over the years in Karnataka. The study used 30 years time series data on area under different crop categories and crops collected from Bureau of Economic and Statistics Bangalore. There was a shift in area under different crops mainly from cereals and commercial crops to pulses, fruits and vegetables during the study period. The concordance coefficient indicated that there were considerable changes in crop area shares over a period of time. There was a considerable increase in cropping intensity over the years.
