| Boron deficiency is a prevalent challenge for plant nutrition supply in many alkaline/calcareous soils. The current research aimed to examine the effects of boron supply to bell pepper plants through fertigation and foliar application. The experiment had seven treatments, comprising a control group, boric acid as fertigation (0.5, 1, and 2 g L-1), and foliar application (0.5, 1, and 2 g L-1) with three replications in controlled greenhouse conditions. The treatments were applied on Lorca bell peppers in a completely randomized design. The results showed that fertigation and foliar application increased all measured characteristics compared to the control group. Increasing the boric acid concentration in foliar application caused a decrease in fruit count per plant, fruit fresh weight, fruit yield per plant, and fruit width. Both fertigation and foliar boric acid applications at a low level (0.5 g L-1) and as separate treatments caused the highest fruit weight, length, width, and fruit count per plant. Higher boric acid concentrations increased chlorophyll a, b, total chlorophyll, leaf carotenoid content, soluble sugars, total soluble solids, titratable acidity, total phenols, and fruit ascorbic acid content. The highest chlorophyll a, b, total chlorophyll, leaf carotenoid content, and fruit ascorbic acid were observed in response to the high concentration of boric acid foliar application (2 g L-1). Overall, the boron supplement as a foliar application (0.5 to 1 g L-1) or fertigation (0.5 to 1 g L-1) improved quantitative and qualitative performance in bell peppers. | ||
