Abstract
Both phosphorus (P) and boron (B) can interact with each other due to their similar properties and P can hinder the uptake of boron by plants. In this study, the effect of P and B concentrations on the growth of rice, sunflower, and maize plants grown under greenhouse conditions in an environment that would induce boron toxicity was investigated. To create a toxic environment, 40 mg kg−1 B was applied to rice plants, and 30 and 25 mg kg−1 B were applied to sunflower and maize plants, respectively. To alleviate the toxicity, 500 mg kg−1 P was added to the respective pots. The results of the study showed that B application reduced the fresh and dry weight of all plant species, while significant increases were observed with the addition of P. Among the applied P sources, TSP was found to be more effective than H3PO4 in terms of fresh and dry weight of maize plants. Plant-B concentrations increased with B application but were significantly reduced by the applied P sources, with no difference observed among the P sources. Plant-P concentrations, which decreased with B applications, increased as a result of P applications. In particular, H3PO4 was found to be more effective than TSP in terms of plant-P concentration, especially in sunflower and maize plants. This study determined that P fertilization can be beneficial in reducing the damage caused by boron toxicity, which is a stress factor that severely limits agricultural production in regions with arid and semi-arid climates.
