Harbovska T. Оptimization of elements of technology for growing vegetable beans in the conditions of the eastern Forest-steppe of Ukraine. - The manuscript

Object: regularities of formation of a high level of yield and quality of vegetable Bean products depending on the elements of cultivation technology. Objective: scientific substantiation and improvement of elements of the technology of growing vegetable beans in the conditions of the eastern forest-steppe of Ukraine. Novelty: for the first time in the conditions of the eastern forest-steppe of Ukraine, regularities in the formation of the yield of vegetable beans depending on the plant placement scheme have been revealed. The productive potential of varieties, their resistance to pests are determined, and the effectiveness of double harvesting of the blade is justified. The relationship between the main parameters of cultural ontogenesis and various abiotic factors is revealed. Yield forecasting models have been developed. The allelopathic interaction of vegetable beans with vegetable crops was established. The effectiveness of introducing compacted crops is justified. Results: regularities of formation of a blade yield of 16.5 t/ha according to the 45x25 cm scheme (density 89 ths pcs. / ha) and seeds 2.1 t / ha according to the scheme 45x15 cm (density 149 ths pcs. / ha); the efficiency of double harvesting of the blade is justified, in which a yield of 24.5–27.2 t/ha is formed, with a profitability level of 97-110 %; the introduction of joint cultivation of vegetable beans with vegetable crops in compacted crops with tomatoes, cucumbers, early potatoes. A patent for the utility model «Method of growing vegetable beans» was obtained. The developments were implemented in farms of the Dvurechansky District of the Kharkiv region on an area of 0.4-8.0 ha.
