The overall usable amount of water on Earth is fixed and finite due to the continuing process of evaporation and precipitation across the hydrological cycle. Just 0.01% of this gross amount is used as surface water in lakes and rivers. A significant amount of surface water is used in agriculture, and therefore good water usage will save more water on Earth. The aim of this research is to increase crop production by computing crop water and irrigation water demand, as well as developing an irrigation schedule in the Thordi village, which is located in Gujarat's semi-arid zone. The crops under consideration are groundnut, chickpea, wheat, sorghum, and millet, which are primarily grown in the Thordi village. The Cropwat, Penman-Monteith method developed by FAO is used to achieve the goal of this analysis. Irrigation scheduling is developed by integrating the timing option of irrigating at critical depletion with the operation option of refilling soil to field capability. This irrigation scheduling option results in the least amount of yield loss. ET0 has a cumulative value of 2054.95 mm/year. The analysis is carried out for five crops, with the maximum CWR and IR for winter wheat crop being 538.7 mm/dec and 522.6 mm/dec, respectively, and the minimum for sorghum being 348.1 mm/dec and 30.2 mm/dec. This research would undoubtedly improve crop production and save more water in the Bhavnagar district's Thordi village.
