The Effect of Zeolite on agronomical characteristics of two rapeseed cultivars under drought stress

To study the Effect of Zeolite on agronomical characteristics of two rapeseed cultivars under drought stress, an experiment was conducted on factorial form in Randomized Compelete Blocks Design with three replication and on crop year 85-86, in the field of Research, Breeding and producing of seed and plants Institute of Karaj. The factors consist of: Irrigation in two levels including normal irrigation (irrigation on the basis of 80 ml evaporation from the A class evaporation pan), cutting irrigation from flowering stage , Zeolite in two levels including non-application and application 10 T/ha and cultivar in two levels including Zarfam and Okapi. The studied characters included: The number of siliques in plant, silique length, the number of seed in silique, the weight of 1000 grains, seed yield, oil seed percentage and oil seed yield. The results showed that most of the simple effects of application of zeolite caused significant preference for all mentioned characters rather than non-application. The results also indicated that the most of interaction effects of application of zeolite caused significant preference for all mentioned characters rather than non-application.
