[en] Soil boron (B) deficiency has been identified in different parts of world in alkaline and low organic matter soils. However, B application is very tricky as a very small amount of B is required to be applied. Two pot experiments were conducted to evaluate B effect on sugar beet yield, industrial sugar content and B uptake. In first experiment, five treatments carrying different B application methods were used. After harvesting, results revealed that B application significantly increased beet yield, sugar content and B uptake. Another experiment was conducted with four different treatments to test how foliar B promotes soil-B uptake via roots. Boron uptake was significantly improved owing to foliar B spray (1.14 mg pot-1) in treatment where B was applied as foliar plus soil as compared to (0.08 mg pot-1) where only foliage B was applied after subtracting B value from their respective controls. The amount of B taken up by plant from soil was calculated higher in treatment where foliar B was applied relative to only soil-B applied, which suggests that foliar B application induced indigenous soil-B uptake. It was concluded that foliar B application upregulated B transporters which enhanced B uptake from soil. (author)
