The study used a dual crop coefficient approach to figure out how much water summer sesame crops need in South Gujarat. They did field experiments with drip and border irrigation systems in 2018 and 2019. By using the SIMDualKc model, they found that the crop water requirement estimates were accurate. The model suggested lower water needs for the initial and end stages of crop growth compared to the traditional FAO method. Using the SIMDualKc model for irrigation scheduling could save water, with an average of 18% less water needed compared to the border system.
