Abstract
The article presents the results of three years of research on the effectiveness of the influence of the biological product Phytohelp, mineral fertiliser Drip Fert N15P5K30+МЕ and bioadhesive Liposam on the structure of the winter garlic yield of the Lyubasha variety under drip irrigation. The relevance of the research is due to the search for new approaches to the development of technological methods for growing winter garlic, taking into account the specific conditions of unstable moisture in the Forest-Steppe. The purpose of the article is to establish the optimal doses and the ratio between them to achieve an increase in the quality and yield of winter garlic. The study was conducted on the experimental field of the Department of Vegetable Growing of the National Assessed Contribution of Ukraine of the Uman National University of Horticulture on podzolised heavy loamy black soil in 2017-2019. As a result, it was proved that in the conditions of the Right-Bank Forest-Steppe of Ukraine on podzolic chernozem under drip irrigation, a higher yield was obtained in plots with the combined use of the biological product Phytohelp at a rate of 1-2 l/ha, mineral fertiliser Drip Fert N15P5K30+МЕ and bioadhesive Liposam at a rate of 1 l/ha. This resulted in an increase of 9.0-10.6 t/ha compared to the control variant, respectively. Using the biopreparation Phytohelp and bioadhesive Liposam at a rate of 2/1 and 1/1 l/ha, a yield of 16.6-17.1 t/ha was obtained, where the increase to the control was 7.7-8.2 t/ha. The effect of foliar fertilisation with Drip Fert N15P5K30+ME (4 g/2 l of water or 0.5 c/ha) on the yield of winter garlic was determined. The increase to the control was 1.6%. The results of this study may be useful for agricultural enterprises and farmers who grow garlic and other crops
