Three strict field trials were conducted in 2003–2006, involving foliar application of boron to ten cultivars of winter wheat. Boron was applied as 175 g . ha-1 of boracic acid. Foliar fertilization treatments caused a significant grain yield increase of four out of ten winter wheat cultivars. The average yield increment ranged between 9 and 15%. The nutritional demands of six other cultivars for boron were much lower. Although the foliar fertilisation with boron increased the concentration of this element in the shoots of these cultivars, they did not respond with higher yield to the application of this element.
