YIELD AND YIELD COMPONENTS OF CANOLA AFFECTED BY SULPHUR LEVELS AND APPLICATION TIMINGS

Canola (Brassica napus L.) a conventional oil seed crop, as winter season crop whichcan be successfully grown in Pakistan. Present research was conducted to study “yield ofcanola as affected by different sulphur (S) levels and application timings” at Agronomy Res.Farm, Univ. of Agriculture, Peshawar in season 2014-15. Canola crop was sown under sulphurlevels of 30 and 40 (kg S ha-1) with three timing of S application (full at sowing, split applicationand rosette stage). Experiment was designed in randomized complete block design replicatedfour times. Results showed that more number of pods plant-1(278), grain pod-1(21), thousandgrain weight (4.1 g), biological yield (3911 kg ha-1), grain yield (1317 kg ha-1) and harvestindex (29 %) were significantly affected by different sulphur levels and application timings.Data revealed that equal split application at rate of 30 kg S ha¯¹ was more efficient ascompared with full at sowing or rosette stage. From this study, it was concluded that yield andyield components were substantially improved by the split application of S at 30 kg S ha¯¹ atsowing and rosette stage
