According to the increasing demand of edible oil, an experiment was conducted in order to evaluate the response of canola to row configuration, humic acid and sulfur application at Agronomy Research Farm, The University of Agriculture Peshawar, during Rabi season 2015-2016. The experiment was laid out in RCB design replicated three times. The plot size was 14.4 m-2having 12 rows, 40 cm apart. The experiment was consisted of three row configurations (solid rows), 3 solid rows + 1 skipped row (3:1 ratio), 2 solid rows +1 skipped row (2:1 ratio), having two humic acid levels (0 and 4 kg ha1) and four sulfur levels (0, 15, 30, 45 kg ha-1). Crop growth rate (5.1 g m-2 d1), number of grains pod-1 (22), grain yield (1657 kg ha-1), oil yield (749 kg ha-1), oil content (45.2 %), glucosinolate content (14.8 u mol g-1) and erucic acid (1.7 %) were significantly higher with 2:1 ratio. Sulphur at the rate of 45 kg ha-1 had significantly high number of seeds pod-1(23), 1000-grain weight (4.5 g), grain yield (1790 kg ha-1), oil yield (809 kg ha-1), oil content (45 %), glucosinolate content (19.3 u mol g-1) and erucic acid (1.9 %),while sulphur at the rate of 30 kg ha-1 significantly increased crop growth rate (5.1 g m-2 d-1). Sulphur at the rate of 45 kg ha-1, having row configuration of 2 solid row + 1 skipped row are recommended for higher seed yield, oil yield and oil content of canola at Peshawar valley.
