Climate and agriculture are inextricably linked. While, the magnitude of climate change impact varies greatly by region, it is expected to have an impact on agricultural productivity and shifting cropping patterns. In this context, the present study was an attempt to analyse the rainfall changes in Haveri district and impact of these rainfall changes on Agriculture in the district. The tabular analysis, compound growth rate analysis, correlation analysis and functional analysis were used for analysing the data. The growth rates for area, production and productivity of major crops in the district revealed that there was a decrease in the area under paddy (-3.87%) and increased production (3%) and productivity (7.18%) of Paddy. In case of Maize and groundnut area (8.06 &3.23%) and production (5.84 & 0.71%) showed positive growth rates and productivity (-2.05 &-2.44%) was negative in both crops. The study also revealed that there was a high degree of positive correlation between the rainfall and paddy production (0.80), rainfall and Paddy productivity (0.88) compared to Maize and Groundnut. The study also found that the variable pertaining to actual rainfall had a positive and significant impact on the paddy productivity at 10% level of significance but in case of Maize and Groundnut productivity the variable pertaining to fertilizer had a positive and significant impact at 1% level of significance than the rainfall
