The effect of drought stress on yield and components of three varieties of autumnal rapeseed in the south eastern region of Isfahan, utilizing four irrigation regimes (i.e. No irrigation from flowering stage on, No irrigation from the podding stage on, No irrigation from grain filling stage on, and a normal irrigation regime after 80 mm evaporation from class A evaporation tube) were studied. An arrangement of split plot in the form of randomized complete blocks in three replications was carried out during the cultivation season of 2003-2004. Drought stress from flowering stage on had deleterious effects on the yield of oil, oil performance, seed yield and its components, the number of pods in plant, number of seeds in pod, the weight of a thousand seeds, yield of seed, yield of oil and oil performance for the control group were 81.5, 23.3, 3.5 grams 2730, 1332 kilogram in hectare and %52.11 respectively. The same variables were 46.7, 17.8, 2.7 grams, 2206, 1098 kilogram in hectar and percentage47.89 in treatment of irrigation from the flowering stage onwards. The results showed that rapeseed can have acceptable yield with the least available water, but in case of optimum irrigation, it can have high production.
