Abstract:

In many cultivated areas of the world, boron element is either inadequate or soil characteristics have restrictive features about boron uptake. During fertilization, application amount of boron element can cause insufficiency or toxic effects. Boron is a necessary element for many physiological and biochemical reactions that occur in plants. Soils’ physical and chemical properties changes due to dissimilarity of properties such as parent material or ecology and this dissimilarity affects uptake of nutritional elements. There have been different boron sources that can be used in agriculture and properties of each are different. A pot study, in which corn plant’s nitrogen and boron uptake has been observed using 5 different boron sources in soil that has 7 different properties where the B level in soil and soil characteristics are different, was carried out. In the study, maize variety of Sele (Zea Mays L.) was used, applied at the rate of 1.5 kg B ha^-1 to pots and as boron source ground colemanite (2CaO.3B₂O₃.5H₂O), borax decahidrate (Na₂B₄O₇.10H₂O), borax pentahidrate (Granubor) (Na₂B₄O₇.5H₂O), sodium metaborate tetrahidrate (NaBO₂.4H₂O), boric acid (H₃BO₃) were applied. Until plant’s harvest day, NPK nutrient requirements were supplied. The plants were harvested after eight weeks. Dry matter yield was recorded, total N and B contents in plant were determined. In the discussion part, different soils’ restrictive soil characteristics and correlations between plant’s N and B contents were discussed. When soils’ B content was taken into consideration, differences between soils in their boron uptake with additional boron fertilization were noticed. pH, lime and organic matter contents of soil characteristics were determining factors. Plant’s N contents differ in accordance with soil types. Significant differences in boron concentration of the plant in terms of applied boron sources were noticed. Results show that in order for plant to benefit from the boron element, it is necessary to apply suitable boron fertilizer considering restrictive factors of the boron level in the soil and soil characteristics.
