Response of spring wheat to foliar fertilization with boron under reduced boron availability
The study focused on the effects of foliar fertilization with boron applied to spring wheat grown on sandy soil, low in available boron, under the conditions of simulated drought stress and the soil pH modified by liming. The study involved pot trials set up in a greenhouse. Wagner’s pots, each containing 6 kg of light soil, served as experimental units. It was demonstrated that foliar application of boron was effective in mollifying the unfavourable wheat growth and nutrients uptake conditions (drought and soil reaction change). The fertilization alleviated the results of the limited availability of boron, significantly increasing the grain and straw yield mass and enriching the yields with boron. The highest rates of boron used for foliar application (7 and 9 cm3 0.3% H3BO3⋅pot-1) raised the concentration of this element in wheat grain up to a level comparable to the reference data.
