Economic efficiency of the influence of the adaptogen “Epin-extra” on growth, development, yield of cucumbers in film greenhouses of Central Yakutia

Abstract

Relevance. In peasant-farm conditions and conditions of subsidiary plots, with a wide variety of growing times in greenhouses, which are very different in equipment, heating and use, it is necessary to clarify the agro-ecological terms and introduce regulators of the growth and development of cucumber plants. The use of the adaptogen increases the yield. The aim of the research was to consider the economic efficiency from the use of the adaptogen “Epin-extra” on the growth, development and productivity of various varieties of cucumbers when grown in spring-summer film greenhouses of the Megino-Kangalassky ulus of the Republic of Sakha (Yakutia). Research methods were used according to the methods of the State Commission for Testing and Protection of Breeding Achievements of the Russian Federation [7, 8, 9]. The calculation of economic efficiency was carried out on the basis of the financial costs included in the technological map and the actual costs per 1 hectare according to the method of S.V. Melnikov.Results. As a result of the research it was found that with a two-fold treatment with a solution of Epin-extra, the development of the main phenological phase of flowering is accelerated for 6 days from control (without treatment with an adaptogen). At the same time, the prevalence of such diseases as ascochito decreases to 1.7%, and the prevalence of root rot is 2.5-3.2 times lower with 2-fold processing, depending on the hybrids. The use of the Epin-extra adaptogen solution increases the quality of products -marketability and weight of cucumber fruits. Due to the use in small volumes, ease of use, the Epin-extra solution increases profitability up to 58.1% with double processing on the Stella F1 hybrid and up to 46.4% in the Maisky F1 hybrid.
