NON-WATER-STRESSED BASELINES FOR CALCULATING CROP WATER STRESS INDEX (CWSI) FOR ALFALFA AND TALL FESCUE GRASS

The lack of transferability of the Crop Water Stress Index (CWSI) baselines, together with the restriction of havingto make required measurements close to noon and under clear-sky conditions, are major drawbacks that restrict the use ofthe empirical CWSI method for irrigation scheduling. The objectives of this study were to: (1) evaluate the effect of solarradiation (Rs) on the non-water-stressed baselines (NWSBs) of alfalfa (Medicago sativa L.)...
