Abstract: A field study was conducted on canola during 1999-2000 at Arid Zone Research Institute, Bahawalpur. The treatments included the two varieties of canola (Dunkled and Rainbow) and three planting densities (10, 20 and 30cm). The objective of this study was to determine the response of canola to different planting densities for days to 90% germination (DG), days to 50% flowering completion (DFC), seed yield Kg ha-1, plant height, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, pod size and number of grains/pod. On average variety dunkled with planting density (10cm) produced higher grain yield of 2222.27 Kg ha-1 as compared to variety Rainbow and other planting densities (20, 30cm). The planting density 30cm produced lowest yield of 1704.33 Kg ha-1. In case of number of primary branches per plant, number of pods per plant and seed yield the results were significantly effected by different planting densities.
