Plant-available water $(\theta_{PAW})$ in soil lies between Field Capacity $(\theta_{FC})$ (suction pressure $\approx 0.33\text{ bar}$) and Permanent Wilting Point $(\theta_{PWP})$ (suction pressure $\approx 15\text{ bar}$): $\theta_{PAW} = \theta_{FC} - \theta_{PWP}$ To prevent yield reduction, irrigation is applied when soil moisture reaches the Management Allowed Depletion (MAD) level, typically set at $50\%$ of available water. The Crop Water Stress Index (CWSI) quantifies plant moisture deficit using canopy-to-air temperature differences $(T_c - T_a):$ $CWSI = \frac{(T_c - T_a) - (T_c - T_a)_{lower}}{(T_c - T_a)_{upper} - (T_c - T_a)_{lower}}$ Where subscript lower represents a non-water-stressed baseline (transpiring at potential rate) and upper represents a fully stressed non-transpiring canopy. In water-scarce agricultural belts across Western India, conventional scheduled rotational canal irrigation frequently causes either root-zone waterlogging or severe crop stress....
