The long term behaviour of rainfall is necessary to study over space with different time series viz. annual, seasonal, monthly and weekly as it is one of the most significant climatic variable. Rainfall trend is an important tool which assesses the impact of climate change and provides direction to cope up with its adverse effects on the agriculture. Nine different stations of Solapur district were selected to carry out trend analysis where rainfed agriculture is major practice. The daily rainfall data of 57 years (1961-2017) of all stations has been processed out study the rainfall variability. To detect the monotonic trend, the non-parametric Mann-Kendall test was applied and the magnitude of trend is estimated by using Sen’s Slope estimation method. The declining trends for annual, seasonal and monthly rainfall were found to be statistically significant. Most of the considered time series in different tahsil of Solapur district showed significantly decreasing trend in rainfall, so judicious utilisation of available water is necessary for sustainability in crop production.
