Abstract:

The performance of rapeseed cultivars (Brassica napus L.) was evaluated using various sulfur levels at the Agriculture Research Institute (N) Mingora swat, Pakistan during Rabi season 2012- 13. The experiment was laid out in randomized complete block design with four replications. Four level of sulfur (0, 15, 30, and 45 kg ha-1 ) and four cultivars of rapeseed (Oscar, Bulbul-98, Dunkled, and Abasin-95) were used. Rapeseed cultivars were significant for all the parameters. The cultivar Oscar had the maximum capsules plant-1 (360), seed capsule-1 (24), 1000 seed weight (3.38 g), seed yield (2340 kg ha-1 ), oil yield (1132 kg ha-1 ) and harvest index (17%) as compared with other rapeseed cultivars. Sulfur application was significant for all parameters. Plots treated with 45 kg S ha-1 produced maximum capsules plant-1 (407), seed capsule-1 (26), 1000 grain weight (3.61 g), grain yield (2701 kg ha-1 ), oil yield (1291 kg ha-1 ) and harvest index (18%) as compared with control plots. It was concluded from this study that sowing of cultivar Oscar with 45 kg S ha-1 seems to the best choice for rapeseed producer in the agro-ecological condition of Swat valley.
