Influence of cultivation technology elements on yield of cucumber hybrids in spring greenhouses in Western Siberia

Crop yields fluctuate greatly during the spring-summer crop rotation depending on agricultural technologies and varieties used, as well as on meteorological conditions during the year. Accordingly, it was necessary to consider the issues of progressive cultivation technology in spring greenhouses. The main methods were the use of environmentally friendly preparations and grafting, which is a popular procedure nowadays. The studies were carried out in the “Sadovodstvo” laboratory of Omsk State Agrarian University educational and experimental farm in 2018-2021. Observations, records and analyzes corresponded to generally accepted methods. Phenological and biometric studies were carried out according to “Methods of field experience in vegetable growingˮ (S.S. Litvinov. M., 2011). Statistical data processing was carried out according to B.A. Dospekhov methods. The purpose of the study was to evaluate the impact of cultivation techniques on the yield of cucumber hybrids in spring greenhouses in Western Siberia. The study objectives included determining the effectiveness of individual elements of technology which were feeding, grafting, and the use of biological products. The experiment was carried out in a greenhouse equipped with a drip irrigation system. Cucumber hybrids were used as the study object. On their roots, dressing with peat gel was carried out, and they were treated with biological preparations and grafted onto hard-barked pumpkin. Studies were carried out separately for each element, and the effect on yield was also taken into account individually. When using fertilizers, a variant with top dressing with 2 ml/l peat gel (19.9 kg/m2) was singled out. Grafting increased the cucumber yield from 15.4 to 16.8 kg/m2. Variants processed with EmEko and Fitoverm preparations showed an increase in yield by 0.8-1.3 kg/m2.
