Abstract

A field trial as a split plot design based on randomized complete block design with three replications was conducted on six winter RAPESEED (Brassica napus L.) varieties in 2005 season in research farm of Kabootar Abad, Esfahan. Treatments selected based on using three different moisture regimes including 1) Application of water when 80% evaporation occurred from class A evaporation pan to physiological maturity as control treatment 2) Stopping water application since flowering stage and 3) Stopping water application since grain fill stage. The results indicated that stopping water application since flowering stage caused YIELD components to reduce significantly and thus had undesirable effect on YIELD where reductions in number of pod per plant (from 79.2 to 50.1), number of grains per pod (from 50.8 to 40.8) and weight of 1000 grains (from 3131 to 2584 gr/ha) were observed. Seed oil content was also found to be reduced in that treatment (from 48.5% to 46.6%). The studied varieties revealed significant differences in all measured traits. The variety of Zarfam had the highest grain YIELD and seed oil content in various irrigation regimes and the SLMO46 ranked next. Considering the high potential of these two varieties in producing oil in stress condition, their capability to be cultivated in stress prone regions is realized.
