Abstract
Berseerri variety synthetic -3 was sown under water depletion levels. of 50 (M 1), 65 (M1), 80 (M3) and 95 96 (Ma) depletion of available m&isture for two years i Northern Punjab and Actual Evapotranspiration, (EtA, Potential Evapotranspirat-ion (EtP) and Pan Evaporation were calculated. Consumptive use of water during the season was 774, 686, 642 and 594 mm as calculated by gravi-metric method and 762, 694, 642 and 615 mm with irrigation method under 50, 65, 80 and 95 96 depletion of available moisture. Growing season crop coefficients were 1.00, 0.89, 0.83 and 0.74 !MCI) and 1.14, 1.02, 0.94 and 0.85 (KC1), respect-ively. Green fodder yield decreased significantly with increase in moisture depletion level. Crop water use deficiency for Mi & M. was ..statisti-cally non-significant whereas crop water use of (CWLIE) under M4 was significantly less as compared to Mi and M2. ENTRODUCTION Crop production i closely related to climatic conditions of the area. Environmental factors like, temperature, rainfall, solar radiation and transpiration are attaining prime importance in this regard as they are used as parameters for compilation of water requirements of different crops.
