Abstract
The global climate change could have important effects on various weather parameters including rainfall in many countries around the world. The trends of rainfall have a great impact in the existing regions for crop production. This study is carried out to examine the trend of rainfall in Bellary District of Karnataka, India. Rainfall data of 51 rain gauge stations for a period of 40 years (1977–2016) and monthly evapotranspiration (ETo) data of 2007–2016 is considered for the analysis. Rainfall anomaly index (RAI) and IMD method are used to find the trend of rainfall. Meteorological drought severity index (MDSI) is used to assess the severity of drought in the study area. The crop water requirement studies with 10 years whether parameters using Penman Montaith method for crops in Kharif and Rabi season are analysed to assess the necessity of irrigation water for both Kharif and Rabi season. Rainfall anomaly index (RAI) shows the decreasing trend of rainfall, and IMD method shows the occurrence and frequency of various drought. MDSI analysis indicates that the study area is facing moderate drought. Water requirement computations to crops for both Kharif and Rabi season indicate that dry crops can be grown in Kharif season without any irrigation. However, both dry, wet and seasonal crops require irrigation supply in both the seasons.
