ABSTRACT

Over 1999-2001 three two-factorial strict field experiments were carried out to evaluate the applicability of soil boron test (1 mole HClˇdm^-3) to determine boron fertilisation requirements of oat. Three boron application methods (pre-sowing, top-dressing and foliar fertilisation) were the variants of the first factor while four doses of boron constituted the second factor. The optimal oat boron supply in B-deficient soil is noted in the study. Despite an over-optimal boron concentration in plants, fertilisation with the microelement brings statistically significant increases in oat grain yield and a continuous increase in B content in plant tissues. The results call for a verification of the tests of boron concentration in soil (1 mole HClˇdm^-3) and oat plants and reveal the advantage of boron top-dressing and foliar methods in yield-enhancement. Considering the impact of boron application on yield and its chemical composition as well as the level of nutrie
