Abstract: 

Background and objectives: In recent decades, canola is one of the most important oil crops. One of the factors affecting canola yield is sowing date. In Golestan provinces sowing date is delayed because of the unsuitable weather condition during canola sowing such as lack of rainfall and unsuitable condition for soil preparation. Then evaluation of delay cropping effect on yield and yield components and selecting best genotypes and row spacing is essential.
Material and methods: In order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in Gorgan Research Station. This experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 Oct., 12 and 28 Nov. and 12 Dec.) as main plot and row spacing (12 and 24 cm) and cultivar (RGS and Hayola 401) as subplot in three replications. Growth stage, number of silique per plant, number of seed per sillique, seed yield and grain oil content (%) was recorded
.
Results: Results showed that delay cropping had different effect in three years and delay planting had higher risk during dry years. Average seed yield of three years at different sowing date showed that Hayola produced higher yield (3287 Kg ha-1). Seed yield of Hayola and RGS reduced 379 and 410 Kg ha-1 per ten days delay in sowing date. Relationship between mean air temperature during flowering and maturity showed that the effect of increasing temperature on seed number (351 Kg ha-1 loss) was more than seed weight (100 Kg ha-1 loss). Ten days in planting date increased oil percent (1%).
Conclusion: In general, in normal years seed yield reduced 27 Kg ha-1 per one day delay in sowing. In delay planting Hayola cultivar is recommended and increasing row spacing did not have significant effect
