Abstract

Vegetable growing is one of the leading branches of the agro-industrial complex. However, the production of vegetable products does not satisfy the average annual consumption of fresh vegetables by humans. A promising direction of modern vegetable growing is the use of substances that affect the phenological growth and development of plants, provide increased yield and improve the quality of products. The purpose of the research – to determine the effect of plant growth regulators and biological products on the growth and development of Lyrik cucumber plants and crop formation in film greenhouses without additional heating. Methods of research. Field and statistical. The results. The influence of different types of growth regulators on the yield of cucumber fruits in film greenhouses was investigated. An increase in fruit yield by 12,3-18,7% is provided by the complex use (seed treatment and 3-time spraying of plants) of Gulliver Stimul, Vimpel Maxi, salicylic acid, Epina extra and microfertilizers. The effectiveness of seed treatment with the microbial preparation Azotophyt-r and the organo-mineral fertilizer HelpRost rooting agent, which enhances the growth processes of cucumber plants and the increase in the yield of fruits, has also been established. A significant increase in the length of the main stem, the number and area of leaves on the plant relative to the control was proved. The maximum level of cucumber yield is provided by HelpRost rooting agent (18,48 kg/m2), the use of which helps to increase the yield of cucumber starting from the first harvest, while with the use of the microbial preparation Azotophyt-r, significant differences in yield were noted only from the 4th harvest of fruits. Conclusions. For growing cucumbers in film greenhouses, it is effective to use the plant growth regulators Gulliver Stimul, Vimpel Maxi, Epin extra, salicylic acid and microfertilizers (seed treatment and 3-time spraying of plants in the phase of 3-4 true leaves, the beginning of flowering and the beginning of fruiting) A supplement that provides an increase in fruit yield by 1,63–2,48 kg/m2 or 12,3–18,7 %. Seed treatment with the microbial preparation Azotophyt-r and organo-mineral fertilizer HelpRost rooted is also effective, which contributes to the growth of the length of the main stem by 13,6–48,4 %, the number of leaves – by 7,0–20,9 %, the area of the leaves – by 17,8–39,3 % and an increase in productivity by 2,05–3,77 kg/m2 or 13,9–25,6 % relative to the control
