The article notes that vegetable crops are mainly grown by the seedling method in spring film greenhouses. The most common production technology in this case is cassette, using high-quality irrigation. Since modern irrigation ramps are not applicable in spring greenhouses, the design and technology of irrigation of a mobile hose sprinkler was developed by the team of authors of the Federal State Budgetary Budgetary Institution VNII Raduga. To implement this equipment in real agricultural production, it must have investment attractiveness. In this regard, it is necessary to evaluate the economic efficiency of the proposed technical solution for watering vegetable seedlings grown using cassette technology in protected soil conditions. Considering that stationary tubular systems with sprinkler nozzles have already been installed in the spring greenhouses of most vegetable farms, it is advisable to assess the relative economic efficiency (annual economic effect) in comparison with the existing system. The agricultural enterprise Sergievskoye LLC (Kolomenskoye district, Moscow Region) was selected for the study, where the greenhouse complex included three 9x50 m hangar greenhouses in which cabbage seedlings were grown, and irrigation was carried out using stationary systems with deflector sprinkler nozzles. Based on the data on the performance of the hose sprinkler, irrigation technology has been developed, adapted to the conditions of this farm. The economic efficiency assessment was carried out in accordance with the methodology of GOST 53056-2008 "Agricultural machinery. Methods of economic assessment". It was found that the annual economic effect of the introduction of a hose sprinkler when watering cassette seedlings in greenhouses, compared with the existing system, amounted to 412,187 rubles. with a payback period of 35 days. The introduction of a hose sprinkler in Sergievskoye LLC allowed the farm to increase the yield of marketable products by 10-12% from one module of the greenhouse, which is confirmed by statistical data.
