In order to evaluation of zeolite and nitrogen fertilizer application effect on agronomic and physilogical traits of rapeseed (cv RGS003) under water deficit stress conditions, an experiment was conducted in factorial based on randomized complete block design with three replications during 2010 in Qazvin region, Iran. In the where, the two levels of irrigation factor as the normal irrigation (irrigation after 80 mm evaporation from class A pan) as control and irrigation cease from stem elongation stage till end of growth, nitrogen factor was at three levels (0, 75 and 150 kg.ha-1 and zeolite factor (0 and 10tons per hectare) were studied. Results showed that drought stress decreased evaluated traits such as silique per plant (41%), grain per silique (26%), 1000 seed weight (33%), grain yield (52.5%), oil percent (14%), RWC (31.5%) and chlorophyll content (35%). Non-application of nitrogen had adverse effects on total traits and reduced them. However, zeolite application at water deficit stress conditions had positive and significant effect on total traits except of oil percent and chlorophyll content, specially improved grain yield and oil yield. Based on the results of this experiment, application of zeolite (10ton/ha-1) through storage and maintenance of water and nutrients, reduced the intensity and harmful effects of stress in plants and enhances crop yield.
