Solonenko S. Optimization of cultivation technology elements of safflower in the conditions of the Western forest-steppe

The dissertation presents the solution of the scientific problem, which consists in the development of technological measures for the cultivation of safflower in the conditions of the Western forest-steppe: the method of sowing and the method of application of the growth regulator, as well as the definition of more productive and adapted variety of safflower to the conditions of cultivation. The optimum yield of 1.2 t / ha provided by the Soniachny variety with a twin row type (19 + 38 cm), prevailing control of 18.3%. The dispersion analysis showed that factor A (variety) was more influential, by 56.13%, factor B (method of sowing) influenced on 43.84%. The spraying of vegetable safflower plants by regulator of growth regoplant in the stemming phase gave a somewhat greater effect compared to the treatment of seeds, the addition to the Lagidny variety was 0.18 t / ha (23%), in the Soniachny variety - 0.19 (19.3%).
