Abstract

In order to study the effects of SOWING DATE on grain and oil yield, and yield components of four CANOLA GENOTYPEs, an experiment was conducted at Agricultural Research Station of Gonbad during 2002–2004 cropping seasons. The experimental design was a split plot arranged in a RCBD with 4 replications. Four SOWING DATEs (Nov. 5, Nov. 20, Dec. 5 and Dec. 20) were assigned to main plots and four GENOTYPEs (Hyola 401, S-3, Quantum and Option 500) were randomized to subplots. The number of days from emergence to physiological maturity, the number of pod per plant and 1000-grain weight in first year of study was significantly greator than those in second year, because of cooler temperature in the first year. However the effect of year on GRAIN YIELD was not significant. The combined analysis of variance showed that there wasn’t any significant difference between the GRAIN YIELDs of two first SOWING DATEs. The GRAIN YIELD of first, second, third and fourth SOWING DATE were 3417, 3431, 2945 and 2358 kg/ha, respectively. Hyola 401 Hybrid had the highest GRAIN YIELD, due to the greatest number of pod per plant and 1000-grain weight. The mean GRAIN YIELD of Hyola 401, S-3, Quantum and Option 500 GENOTYPEs were 3457,2863, 2763 and 3068 kg/ha, respectively. The OIL PERCENT in the first year of study was greater than second year. The oil content in fourth date sowing was also greater than the others, which could be associated with the heat stress at physiological maturity. Hyola 401 hybrid and Option 500 GENOTYPEs are recommend for sowing in Nov. 5-20.
