Sievidov V. Improving the elements of the technology of growing cucumbers in film greenhouses in the conditions of the Left-Bank Forest-Steppe of Ukraine

Object: processes of growth and development of plants in film greenhouses, formation of productive and qualitative indicators of parthenocarpic hybrids of cucumber, depending on the elements of cultivation technology. Objective: To improve the elements of technology of cucumber cultivation in film greenhouses in the conditions of the Left Bank Forest Steppe of Ukraine (IV light zone). Methods: dialectical and method of hypotheses, experiment, analysis and synthesis, field, laboratory, statistical, calculated. Novelty: The patterns of formation of high level of yield and quality of parthenocarpic hybrids of F1 cucumber have been investigated and experimentally grounded for the first time. The biological features of plants of parthenocarpic hybrids of F1 cucumber of domestic and foreign breeding have been investigated, the duration of the stages of organogenesis in film greenhouses under the conditions of IV light zone of Ukraine has been specified. Results: in the conditions of the film greenhouses of the Left Bank Forest Steppe of Ukraine the expediency of growing parthenocarpic hybrids F1 - Lyric, Courage and Kibria, which in the spring and summer cultivation provided a cucumber yield of 12,4; 14,4 and 17,2 kg / m2, respectively. The evaluation of the seedlings for the cultivation of seedlings by the total yield and the best of them (turf land + white mossy peat (substrate "Jiffy" - made in Estonia) + humus (1: 1: 1)), which provides the highest yield - 14,8 kg / m2 without seed treatment with microbial ABT preparation and 16,3 kg / m2 with treatment. It was found that the planting of seedlings of hybrid F1 hybrids with a density of 3,0 rows / m2 provided the highest yield at the level of 19,2 kg / m2. Level of production: in the farms of Kharkiv region: JSC "Zmiiv Vegetable Factory" of Zmiiv district (2017, 0,1 ha), IC "Vityaz" (2017, 0,5 ha) and C (F) D "Druzhba" (2017, 0,4 ha) of Chuguev district)
