چکیده

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.‎
