Title: Study on Effects of Different Plant Density on Seed Yield of Canola (Brassica napus L.) Cultivars
Abstract: In order to evaluate the effect of planting density on plant density on seed yield of canola (Brassica napus L.) cultivars, a field experiment was conducted in Astara Branch, Islamic Azad University Research Site During 2011-2012. The experiment was laid out according to Randomized Complete Block Design (RCBD) with factorial arrangement having three replications. Effect of three planting densities (50, 70 and 110 plants/m 2 ) on yield and yield components of four canola cultivars (Hyola 401, Hyola 60, RGS and Zarfam) was evaluated. Some of agronomy traits were measured, such as plant height, days to maturity, pod number per plant, number of seeds per pod, Biological yield per plant, seed weight per plant and Seed yield. The results showed these cultivars were significant for all traits. However, plant density was significant for all traits expect pod number per plant. Increasing plant density was associated with a significant decrease in days to maturity, number of seeds per pod, Biological yield per plant, seed weight per plant and increase plant height and Seed yield in cultivars.. Highest seed yield observed in Hyola 401, Zarfam and 110 plants/m 2 density.
