Increasing Irrigation Efficiency by Scheduling Using Cropwat Software

Abstract: Optimum water use in agriculture is more crucial nowadays. This study explores the transformative potential of CropWAT software in enhancing water efficiency and increasing crop yields through precise irrigation scheduling. Our primary goal is to elevate farmers' awareness about the benefits of this advanced tool, particularly in the drought-prone Marathwada region of Maharashtra. We conducted a comparative analysis of two farms: On one land an abundant water supply and another less irrigation water with different types of agricultural soil, as fewer irrigation water sources in Marathwada, known for its challenging water scarcity issues. By considering local climatic, soil, and crop data in CropWAT, we were able to accurately predict the irrigation needs for each crop in the field. The farm in which the water-rich area avoided of over-irrigation, while the farm with less water was given the optimum depth of water then we achieved improvements in water use efficiency. In both scenarios, CropWAT's irrigation scheduling led to significant increases in crop yields. This study highlights the game-changing potential of CropWAT software as a critical tool for modern agriculture. By adopting precise irrigation management strategies, farmers in Marathwada and similar regions can not only conserve precious water resources but also enhance their productivity and contribute to sustainable farming practices. Our findings underscore the importance of embracing technological innovations to secure the future of agriculture in water-challenged environments.
