Cucumber productivity depending on the use of microbiological preparations

Abstract

Relevance. In the modern production of greenhouse products, with hydroponic cultivation of crops, one of the safe ways to increase the quantity, quality of cucumber products and plant protection is the use of microbiological preparations.Methodology. The purpose of our work was to assess the effect of a complex of microbiological preparations on the productivity of cucumber hybrids in winter and spring turnover. The study was conducted in industrial greenhouses during 2021-2022. Long-fruited (Lohengrin F1) medium-fruited (Mewa F1 and Svyatogor F1) and short-fruited (Valigora F1) parthenocarpic cucumber hybrids were selected as research objects. The preparations were applied five times, at 30-day intervals throughout the entire growing period, the first application when planting plants in the production department. Measurements of economically valuable and chemical indicators were carried out weekly. Descriptive statistics and ANOVA methods were used for statistical data analysis.Results. As a result of the research, a positive stimulating effect of a complex of microbiological preparations on the accumulation of raw and dry biomass, an increase in yield and its quality in the studied cucumber hybrids was revealed. The final yield when applying microbiological preparations increased on average from 4.1 to 5.5 kg/m2 in all cucumber hybrids over the two years of study, while the yield of standard products in the total crop structure increased by 2.7% - 6.4%.
