Abstract
A field study was conducted to elucidate the influence of sulphur (5) addition along with recommended fertilizer dose (90-60-0 NPK kg hdi) on the oil contents and yield of two varieties of rapeseed i.e. Chakwal-sarson and Dunkled under medium rainfed conditions during 2002-03. Sulphur was applied 0 0, 10, 20, 30, 40, and SO kg Jul' in the form of gypsum at the time of seedbed preparation before sowing. Data indicated that the application of different doses of S significantly increased the seed yield ranging from 5.2-76.7% while the oil contents were enhanced from 2.7-16.8% as compared to the control (no S application). Other yield contributing traits such as plant height, number of primary branches plant4, siliquae plant', number of seeds siliqua4 and 1000-seed weight also responded positively to the S addition. Chakwal-sarson (1049 kg ha'') produced significantly higher seed yield than the Dunkled (939 kg ha-l), whereas the oil content of Dunkled (43.93%) was more than Chakwal-sarson (43.68%).
