Estimation of crop water requirement is essential for agricultural planning and irrigation scheduling. The aim of this study was to compute the water requirement of wheat and rice crops for all districts of Haryana. Climatic data on maximum and minimum temperature, rainfall, relative humidity, wind speed and solar radiation were used to estimate the reference evapotranspiration (ETo) at different gridded locations by using Penman Monteith method in MATLAB software. Further, the actual evapotranspiration for rice crop grown in the region was estimated by multiplying the ETo with crop coefficient (Kc) values. Subsequently, the effective rainfall and the irrigation water requirement for wheat and rice crops at gridded points pertaining to different districts of Haryana were estimated. Thereafter the trend analysis was performed by using non parametric Mann Kendall test by using MATLAB software. Results indicated that water requirement (ETC) of wheat was increasing significantly for eleven districts viz. Ambala, Bhiwani, Fatehabad, Hisar, Jind, Kurukshetra, Mahendargarh, Panchkula, Panipat, Sonipat and Yamunagar while in case of rice crop it was increasing significantly only for eight districts viz. Bhiwani, Fatehabad, Hisar, Sirsa, Jind, Kurukshetra, Panipat and Sonipat. This work can help in water management practices for better irrigation management.
