V. Ya. Yuriev popup.description2 Study object of research -crops of sunflower parents (SKh1012A, SKh51A, OdOl1A, Kh2301V, Kh526V) and hybrids (Sait, Hudvin, Kadet), biostimulants Vermistim and Bioglobin, bioagent Polymixobacterin, disinfectants Maxim and Tabu, liquid microfertilizer Titon Parostok. Study purpose - to investigate the effects of biostimulants and microfertilizers on the sowing qualities and yields of seeds of sunflower parents and hybrids. Research methods - field and laboratory experiments; collection, accumulation and processing of information on a computer. The effects of pre-sowing seed treatment with plant growth regulators, bioagent, microfertilizers, and seed disinfectants on the growth and development of plants as well as on the yields and sowing qualities of seeds of sunflower parents was studied. The varietal response to the test factors was established. Seed treatment with growth regulators, bioagent, microfertilizers, or with their mixtures increases the seed yields of sunflower parents and hybrids by 0.06–0.14 t/ha and 0.07–0.22 t/ha, respectively, which gives an additional profit within 29,999–69,996 UAH/ha and 787–2196 UAH/ha, respectively, and ensures accelerated introduction them into production. Application of biostimulant Vermistim in combination with microfertilizer Titon Parostok is the most effective method of pre-sowing treatment of seeds of maternal form OdOl1A and sunflower hybrids Sait and Hudvin; Titon Parostok alone and in combination with biostimulant Vermistim or bioagent Polymixobacterin was the best for hybrid Kadet; biogent Polymixobacterin in combination with microfertilizer Titon Parostok showed the best results on parents Kh526V, SKh1012A and SKh51A; Titon Parostok + Vermistim or Titon Parostok + Bioglobin showed the best results on parent Kh2301V.
