| This experiment aimed to determine the crop evapotranspiration (ETc), groundwater input in total water used by wheat crop, and to simulate the CROPWAT model to envisage the crop evapotranspiration rate. To estimate on-field ETc and groundwater contribution the combining lysimeter technique was used. The water levels below the soil surface were kept at 1.60, 2.20, and 2.80 m and each water table depth was replicated three times. The experiment was conducted under silt loam (SL) and silty-clay loam (SCL) soil conditions. The climatic parameters and water balance components were recorded accordingly. The on-field ETc was compared with the predicted ETc by CROPWAT model. Under SL soil, the observed ETc was 442, 427, and 401 mm at the water table depth of 1.60,... |

| This research was intended to determine the groundwater contribution in crop water-use of sesame crop under different water tables depths and to assess the accuracy of CROPWAT model to simulate the evapotranspiration. The method of combining Lysimeters was implemented to investigate seasonal groundwater contribution to crop-water use. The climatic conditions under which crop was grown were monitored, water table depths were maintained (at 1.60 m, 2.0 m and 2.40 m) and all water balance components were measured. The crop coefficient (Kc), ET and reference evapotranspiration (ETo) were determined. The obtained results were compared with the outputs of the CROPWAT model. The results reveals that, the average ET of sesame crop under lysimeter experiment was... |
