Yield and yield component canola cultivars (Brassica napus L) under influence by planting densities in Iran

ABSTRACT: In order to of study yield and yield component canola cultivars (Brassica napus L) under influence by planting densities in during 2009-2010 a research was performed at research farm in Chaloos region of Iran north. The treatments included the two cultivar of rapeseed (Hyola60 and Sarigol) and three row spacing planting (15, 25 and 35). Results indicated that maximum yield of canola the plant to plant distance should be maintained as 15 cm. Among varieties Hyola60 was appeared to be high yielding variety under the existing climatic conditions. On average variety Hyola60 with planting distance (15 cm) produced higher grain yield of 2556.85 (Kg.ha-1) as compared to variety Sarigol and other planting densities (25, 35cm). The planting Distance 35cm produced lowest yield of 1840.34 (Kg.ha-1). In case of number of primary branches per plant, number of pods per plant and seed yield the results were significantly affected by different planting densities.
