Performance of transplanted canola varieties in relation to age of nursery seedlings and inter-row spacings under late sown condition

A field experiment was conducted to study the influence of nursery age and inter-row spacing on growth and yield of canola (Brassica napus L.) varieties under late sown condition during rabi 2009–10. Among different varieties, Hyola PAC 401 produced maximum mean seed yield (15.8 q/ha) which was 11.4 and 26.5% higher than varieties GSL-1 and GSC-6, respectively. The optimum age of transplanting the nursery seedlings for variety GSC-6 was 30 days and it was 45 days for GSL-1 and Hyola PAC 401. Row to row spacing of 30 and 45 cm produced statistically similar mean seed yield in transplanted as well as in direct seeded crop.
