Effects of two boron (B) sources and increasing application doses of both sources on the dry matter yield, B and some nutrients uptake by maize (Zea mays L.) were investigated in greenhouse conditions. Increasing doses of boron (0, 2.5, 5, and 10 mg B kg-1) were applied to soil as borax (Na2B4O7.10H2O) and boric acid (H3BO3) and maize plants were grown for 37 days.
Increasing doses of B were found statistically significant on dry matter yield, boron, phosphorus (P), and magnesium (Mg) uptake. Borax and boric acid doses elevated the B (6.52 - 5.92 mg pot-1) and Mg (49.73 - 49.12 mg pot-1) uptake of maize and the highest values observed at 10.0 mg B kg-1 dose of both borax and boric acid, respectively. Dry matter yield and the nutrient elements uptake / B uptake ratios decreased with the increasing B applications. Boron sources found statistically significant on the amounts of dry matter yield, B, P, and iron (Fe) uptake. Up taken B and P amounts were found high at Borax applications, however, dry matter yield, and Fe uptake was found higher at boric acid applications.
