Responses of Canola to Different Row and Plant Spacings

A field study was carried out to determine growth and yield of canola (Brassica napus L.) at different inter row (30, 45, and 60 cm) and intra row (10, 15, and 20 cm) spacing between 1995-97. The closer row Spacing of 30 cm significantly increased leaf area index (LAD, total dry matter (TDM) in both the seasons over wider spacing of 45 and 60 cm. Similarly closer plant spacing of 10 cm also enhanced LA! and TDM over 15 or 20 cm plant spacing. Seed and oil yield was significantly increased in first row spacing compared with 45 or 60 cm row spacing in both seasons. Swd yield was linearly related to TDM yield, harvest index was not changed. The results suggest that closer spacing of 30 cm is optimum for maximizing seed and oil yield for canola under the agro-ecological conditions of Faisalabad.
