Climate change impact on water requirement of micro irrigated mango orchard under climatic conditions of Udaipur, Rajasthan

A study was carried out to analyze the impact of climate change on crop water requirement (CWR) of mango for Udaipur district of Rajasthan during five years (2014 to 2018). There was significant impact of climate change on daily reference evapotranspiration (ETo), rainfall pattern, crop evapotranspiration (ETc) and CWR. The uneven trend of ETo and Rainfall was for different year. The average daily ETo were maximum for May while, minimum for December months. The ETc was maximum for August, 2015. In this study most of the time, ETc was recorded minimum for month of December. The average CWR for mango tree ranges from 23.3 to 94.7 litre/plant/day during all five years. The trend of ETo, rainfall and CWR of mango crop was found uneven, due to temporal variation in climatic condition of Udaipur region by improper use of natural resources, over industrialization and mining interventions, which results improper future planning for establishment of mango orchard. The result of this study are capable for policy makers and planners of water resources for future planning and helps to conserve water in satisfying crop water requirement of orchard crops.
