Climate Change and Its Impact on Crop Water Requirement of Mulberry (Morus spp., Moraceae) Crop in Yadgir District, Karnataka, India

Abstract

This study was carried out to examine trends in crop water requirement under several climate change scenarios to provide projections of changes in crop water requirement of mulberry. According to Indian Network for Climate Change Assessment (INCCA) and Inter-Governmental Panel for Climate Change (IPCC), scenarios which may be included for assessment were developed from their reports. A CROPWAT-8.0 model was utilized to determine the required water requirements for crops in a variety of climate change scenarios. The estimated and demonstrated growing and reducing trend in crop water requirements of Mulberry over the last 35 years was seen in the Yadgir district in overall displayed. As regards Mulberry, there has been a rising ETc tendency in all study area even if different climate change scenarios are used. It was found that climate variability has an impact on the Mulberry crop's water needs. To help address this, it was suggested that to reduce the risk of yield loss due to changing water availability, water conservation efforts such as rainwater harvesting, soil and water conservation, and increased ground water recharge should be implemented in the study area.
