Climate is the primary determinant of agricultural productivity. Climate change effects agricultural operations in a number of ways, including through changes in average temperatures, rainfall, and climate extremes. Concern over the potential effects of long-term climatic change on agriculture has motivated a substantial body of research over the past decade. The present study was conducted in Dharwad districts of Karnataka state during 2016-17. Descriptive research design was followed to assess the effect of climate change on agricultural operations with a sample of 120 respondents selected randomly. The findings inferred that cent percent respondents noticed negative impacts with regard to crops grown, insect pest infestation and overall health of the crop, negative impacts (97.50%) as expressed by almost all the respondents about time of application of chemical fertilizer, intercultural operation and pesticide use. Among the remaining practices, more than 90 per cent of the respondents mentioned negative impact for 8 practices such as Disease infestation (96.97%), cropping pattern (96.67%), grain yield quantity (95.83%), Harvesting (93.33%), Grain yield quality (92.50%), sowing time (91.67%), Straw yield obtained (91.67%) and intensity of weeds (90.00%). It was also found that majority of the respondents (86.67 %) observed negative impacts for soil fertility and use of chemical fertilizer, no effect of seed rate (86.67%), seed treatment (83.33%), spacing (80.00%) and FYM application (73.33%).
