| Description
| - Boron is the most important micro biogenic nutrient in sunflower nutrition. It is involved in sugar metabolism and is important in energy metabolism where it has a favourable effect on the accumulation of phosphorus compounds and activates a number of enzymes. Boron is also important in integrating nitrogen into nucleic acids and in this way directly affecting the production of proteins; it also stimulates nitrate reduction and synthesis of amino acids and cytokinins. The objective of the vegetation experiment established in 2008 -2010 was to explore the effect of the date of extra-root application of boron on the yield and quality of sunflower. Four treatments were established in the experiment: 1) control -- not fertilised with boron; 2) application of 300 g B ha-1 at the stage of 4 developed leaves; 3) application of 300 g B.ha-1 at the beginning of elongation growth; and 4) split rate of B -- application of 150 g B ha-1 at stage V-4 (4 developed leaves) and 150 g B ha-1 at stage R-1 (terminal bud forms a miniature floral head rather than a cluster of leaves). Extra-root B nutrition increased the B content in leaves and stems and increased the biomass production of sunflower plants. The increase in dry matter increased the uptake of nutrients by the stand which is essential for achene production. Supplementary boron fertilisation at stage V-4 increased the N content in the plant. Boron had a considerable effect on achene production. The highest increase in yields was discovered after supplementary fertilisation at stage V-4 (by 9.2 %) and with split rates (by 5.5 %). The relative increase in the oil content after foliar dressing with boron, which ranged within 1-3 %, was not significant. The higher yields and stabilised oil content increased oil production (t.ha-1), most markedly after supplementary fertilisation at stage V-4 (by 11.8 % rel.). Only the content of stearic acid increased significantly after foliar application of B at stage V-4 and split suppleme
