Study Object - crops of sunflower parental forms and hybrids, plant growth regulators Dominant, Noostim, Vermiodis, microfertilizer Nanomix-sunflower, dye Semia-color (b), dressers Maxim XL 035 FS and Tabu. Purpose - to study effects of plant growth regulators and micronutrients on sowing characteristics and yield capacity of seeds of sunflower parental forms and hybrids. Study Methods - field and laboratory experiments, collection and accumulation of information and processing it on a computer. The influence of new plant growth regulators, micronutrients, dye, and dressers on plant growth and development as well as on yield capacity and sowing qualities of seeds of sunflower parental lines was investigated. Variety response to the test factors was determined. Incrustation of seeds with dye Semia-color (b) or incrustation followed by spraying plants with growth regulators, microfertilizers or with mixtures of thereof increased yields of seeds of sunflower parental forms by 0.06-0.23 t/ha and of sunflower hybrids - by 0.16-0.37 t/ha, which provides an additional revenue of 51,050 - 78,292 UAH/ha and 1,438 - 3,294 UAH/ha, respectively, and ensures accelerated implementation of them into production. The most effective way to increase seed productivity of female form Skh2122A is incrustation of seeds with agent Dominant; of female forms Skh808A ? H1002B, Skh1002A ? Kh1010B and hybrid 'Zlatson' - incrustation followed by spraying with agent Noostim or Vermiodis; of parental form Kh06135V and hybrid 'Ryurik' - incrustation of seeds with agent Vermiodis and incrustation followed by spraying with agent Dominant; of hybrid 'Sirius' - incrustation of seeds followed by spraying with agent Vermiodis; of parental forms Kh06134V and Kh720V - incrustation of seeds
