Sunflower is a plant characterized by very fast growth. For this reason, it is mostly possible to apply only one or two foliar treatments during vegetative stage, at the beginning of vegetation in combination with appropriate herbicide. Since sunflower is grown in places with more sunny days and less precipitation, of key importance is formation of strong and robust root system, which will be able to supply the plant with nutrients. In addition to the root system, high sunflower yield requires good pollination, therefore on soils deficient in boron (sandy soils) supplementary nutrition with FitoFert Bor Max 20 is recommended.
