The effect of low irrigation in growth stages on yield and components yield oilseed rape cultivars in sistan
In order to determining the effect of low irrigation in growth stages on yield and components yield oilseed rape cultivars an split-plot experiment on based of randomized complete block design with three replication was conducted in zahak Agirculture Research station of zabol, during two seasons (2002- 2003 and 2003-2004 ).This site located in Southern Fast Iran country. Cultivars on two level (C1=(pf/7047) Sarigol and C2=Hyola308) established in main plot and low irrigation in six levels include (T1(control)=irrigation in roset, buding,flowering,pod formation and filling grain stages T2=irrigation in buding,flowering,poding and filling grain stages T3=irrigation in buding,flowerin and pod formation stages T4=irrigation in roset,flowering and filling grain stages T5=irrigation in buding and pod formation stages T6=irrigation in flowering and pod formation stages. Results achieved from combination analysis showed low irrigation had difference significant at the 1％ level on number silique in plant, number seed in siliqua, 1000seed Weight, hieght, grain yield, oil percent and oil yield.Comparison between means showed that T1 and T2 treatments had highest grain yield (3080 and 2970 kg/ha respectively)than T6 treatment with least grain yield(1855 kg/ha) have 23％ and 25％ more grain yield respectively. Effect cultivars on Silique number in plant, height, at the 5％ level and on seed number in silique,grain yield,oil yield, was significant at the 1％ level.Hyola 308 hybrid with 2945kg/ha showed 21％more yield than PF/7047 cultivar. The most and least oil percent were concerned to T1(control) and T5 (47％ and 44％) respectively. Cultivars had not Significant difference. But From aspect oil yield Hyola 308 hybrid 39％ had increased than PF/7047 cultivar. The interaction effects of treatments measured on yield and components yield were not significant.
