Application of Zeolite in water use optimum on vigority of canola seed (Licord cultivar)

To evaluate the effects of application of Zeolite and different levels of irrigation and vigority of canola seeds, the experiment was done on a factorial based on a Randomized Complete Block Design whit four replication in 2009 to study the effects of the usage of the zeolite and the different levels of the irrigation on the germination and the vigority of the rape seed cultivars. The factors included three levels of the Zeolite (0, 10, 20 tones in the hectare) and three levels of the irrigation (the irrigation after 80,120,160 millimeter evaporation from class A pan) based on the factorial on the rape cultivar of Licord. The used seeds were produced based on the levels of the Zeolite and the drought stress and they were stored in storage for two months and then were used in this experiment. The studied seeds were determined based on the three common tests including the standard germination test; accelerate ageint test and cold test. In each three test, in the condition of the drought stress, the usage of the zeolite caused two increases significantly some characters. The comparison of the means showed that the different levels of the zeolite have the significant effect on the ratio of the root to the shoot, the length of the shoot, the length of the root, the dry weight, FGP. The different levels of the irrigation also have the significant effect on these characters.
