Abstract

This research was carried out to investigate changes in crop water stress index (CWSI) of bean and its relationship with soil moisture under different regimes of Drip irrigation at Lorestan University College of Agriculture. For this purpose, three varieties of Pinto bean Contains sadri (S), COS16 (C) and Kusha (K) in main plots and irrigation regimes in four levels including T120 (120% crop water requirement), T100 (100% crop water requirement) T80 (80% crop water requirement) and T60 (60% crop water requirement) were subplots. The results showed that in all three cultivars of the beans, the highest values of CWSI during the season were related to severe tension (T60) which was equal to 0. 3 and in contrast to (T120), the lowest values of water stress index and Equal to 0. 14. The correlation coefficient between of soil moisture content and CWSI was found to be 0. 91 which was significant at 1% probability level, and therefore a relation was used to estimate the soil moisture content using the CWSI. Finally, using the proposed relationship and the allowable drainage coefficient, the threshold value of CWSI was 0. 21.
