    Growth processes of sunflower plants depending on growth factors
    (Полтавський державний аграрний університет, 2024) Shakalii, S. M.; Cachko, I. V.; Шакалій, Світлана Миколаївна; Сашко, І.
    The growth properties of different sunflower hybrids differ among themselves according to such indicators as initial growth energy, onset time and duration of development phases, period of onset of maturity, morphological parameters of plants, yield properties and quality indicators of products. At the same time, in the same hybrid, due to changes in climatic or technological growing conditions, the main indicators may also change.

    Influence of bioproducts on sowing quality of sunflower seeds
    (2025) Shakalii, S. M.; Cachko, I. V.; Шакалій, Світлана Миколаївна; Сашко, І.
    Obtaining low sunflower yields is largely due to the negative impact of diseases, pests and weeds. On the other hand, the growth and development of sunflower plants is influenced not only by abiotic factors1. An exceptional role in this process belongs to climatic conditions, since they largely determine the nature of the relationship between all components of the agrocenosis. Therefore, an important problem is not only the fight against diseases and pests, but also with the entire spectrum of other stress factors of the external environment2.

    Sunflower water consumption depends on factors growing
    (2024-05) Cachko, I. V.; Shakalii, S. M.; Сашко, І.; Шакалій, Світлана Миколаївна
    In agriculture, a very important indicator is the coefficient of total water consumption, which characterizes how much water is used to form one ton of products, and the lower it is, the better. In the conditions of Ukraine, a moisture deficit during the entire growing season of crops is characteristic, therefore, the optimization of water consumption is one of the most important factors that determines yield. In the conditions of arid Ukraine, moisture is at the first minimum and acts as a limiting factor in the formation of productivity and the most common stress factor that limits the growth processes of plants.
