There is usually a positive yield response when sulfur (S) is applied to rapeseed (Brassicarapa L.) plants grown on S-deficient soils. Canola, being a conventional oil seed and winter season crop that is grown successfully in Pakistan. Research was conducted to study "phonological traitsof canola in response to different concentrations of ammonium sulphate foliar spray" at Agronomy Res. Farm, Univ. of Agriculture, Peshawar in season 2014-15. The experiment consist of ammonium sulphate foliar

Results showed that Number of leaves and number of branches were non significant while the rest phonological traits were affected significantly. Less days to flowering (303), Days to pod formation (350), Days to maturity (469), and more biological yield (3856kg ha-1) and grain yield (2360kg ha-1) were recorded for 1% foliar application of sulphur. While maximum data were recorded in plots with no foliar spray for (days to flowering, days to pod formation and days to maturity) and less biological and grain yield. Data revealed that foliar application of ammonium sulphate at rate of 1% S was more efficient as compared with control for the phenologocal traits of canola. From this study, it was concluded that phonological traits were substantially improved by the foliar application of Sulphur@1%. organic matter (0-1%), 70-95 percent in phosphates and 20-60 percent soils in potash.
