摘要：An experiment to study the influence of sulphur on nitrogen use efficiency, yield and quality of Brassica species was conducted at N D F, KPk Agricultural University, Peshawar during rabi season 2012. The experiment was carried out in RCB design with split plot arrangement, having three replications. Four nitrogen levels two sulphur foliar application and three Brassica species were used in the experiment. Combination of N and S were allotted to main plots and species were allotted to subplots. N application had a non-significant effect on all the studied parameters except 1000 grain weight, biological and grain yield, protein content and N-Use Efficiency. S foliar application significantly affected 1000 grain weight, biological and grain yield, oil content, protein content and N-use efficiency. 1000 grain weight, biological and grain yield, oil content, protein content and N-use efficiency. N application at 100 kg ha~(-1) showed a significant increase in grain yield. It is concluded that specie E12 fertilized with 100 kg N affix to sulphur gave maximum grain yield.
