| Abstract | ||
| A field experiment was carried out to study the effect of spraying ascorbic and citric acids on canola grown on a sandy soil in Ismailia Governorate, Egypt, the design was a randomized complete block, factorial. Factor 1: ascorbic acid spray at 4 rates. Factor 2 : Citric acid spray at 4 rates . Rates in each were 0, 144, 192 and 240 g acid ha-1 of spray. Thus there were 16 different combinations. Foliar spray was applied three times: 40, 60 and 80 days from sowing, each of 1000 L ha-1.Yields of seeds, pods, shells, oil and oil percentage were increased with increasing the rate of acid addition. Seed yield, No. seeds pod-1, pod yield and pod shelling were increased with addition rates of 240 g solution ascorbic ha-1 without citric acid. Shell yield and 1000 seed weight were increased with spraying 240 g ha-1 from both of ascorbic and citric acid. | ||
