تاثیر کاربرد زئولیت روی تولید پروتئین و عملکرد پروتئین عدس در شرایط کمبود آب

The objective of this study was to determine the effect of different rates of zeolites and drought stress on some Morpho-Physiological traits in Lens culinaris. Factors were considered as two levels of irrigation (irrigation at field capacity (FC) and 50 % (FC) which applied in two-leaf stage and four levels of zeolites (0, 10, 20, 30 ton/ha). Results of ANOVA showed the significant effect of irrigation and zeolite based on protein (%) and biological yield and the significant effect of irrigation for protein yield and proline. The results indicated that water deficit stress significantly decreased protein (%) and yield, whereas the application of zeolites compensated the negative effect of drought stress, especially in high rates of polymer application (30 ton/ha). The highest the biological yield were obtained from application of 20 ton/ha zeolite that with 30 ton/ha did not statistically significant. The highest (%8/62) and lowest protein content (%6/68) was obtained from application of 30 ton/ha zeolite and control treatment. These findings strongly suggested that the irrigation intervals of lens could be increased by application of zeolite. The highest protein percent and yield were obtained from field capacity irrigation.
