Asian vegetable crops are rapidly expanding in Florida in the last decade due to their health benefits combined with their high profitability. These crops can help increase vegetable growers’ income and diversify Florida’s crop production, and they are new to most Floridians. This new 5-page article provides a general overview of bok choy for vegetable growers, crop consultants, certified crop advisors, Extension agents, and graduate students. Written by Hai Liu and Guodong Liu and published by the UF/IFAS Horticultural Sciences Department.https://edis.ifas.ufl.edu/hs1337

The object of the research in the chapter is green vegetable crops grown in a manmade environment. The purpose of the presented research is to study the process of growing plants in a man-made environment, the main influencing factor of which is the man-made sources (LEDs) emission, as well as to design and construct the installation (irradiation chamber) for implementation of the studied technology. The chapter presents the results of experiments conducted by a team of researchers, which allowed to determine the technological process indicators of growing green vegetable crops in a man-made environment, and also to develop designs for small-sized irradiation chambers with automatic control, both for laboratory research and for small business and private use. Studies were conducted in different regions of the country and combined the efforts of several scientific groups of researchers. The chapter presents the results of researching these areas conducted by the authors, which are completely original.

The article discusses the results of studies of the peculiarities of growing seedlings of green vegetable crops (lettuce, Krupnokochany variety and basil, Crimean Violet variety) in protected ground conditions (year-round glazed greenhouses) on the basis of UNPK Agrocenter of the Saratov State Agrarian University. The difficulty ofgeneration of  seedlings of these vegetable crops is that they are small-seeded (lettuce) and hard-growing (basil), demanding on the soil substrate. To reduce the pesticide load when growing these crops and improve the ecological quality of products, it is recommended to use the most effective growth-regulating preparation  Epin-Extra, which has a stimulating effect that improves the quality of seedlings. It is shown that for growing basil seedlings of the Crimean Violet variety, a soil mixture containing peat - 50%, field soil - 30%, turf soil - 10%, sand - 10% should be used.

The article provides a marketing review of the green crops market, analyzes expert-import operations and sales channels for this type of product. The ranking and grouping of the main types of vegetable and melon crops in Ukraine by the indicator of gross production is carried out. Thus, according to the State Statistics Committee, despite the fact that Ukraine produces more than 40 types of vegetable and melon crops, about 10 main vegetable and melon crops, which are in the first group, are grown in masse. Thus, the first group with a gross production of over 1 000 thousand tons included 11 crops: borscht, cucumbers, pumpkins, zucchini and watermelon. The share of this segment in the total gross collection is 96.3%. The second group with a gross production of 100.1 to 1 000 thousand quintals includes such types of vegetable crops as melons, eggplants, sweet corn, leeks, green peas, cauliflower and broccoli, radishes, Chinese cabbage, green peppers. The group’s share in the total production structure is only 3.3%, and in the total sown area does not exceed 8%. The third group (with a gross production of up to 100 thousand centners) is a group of green vegetable crops. The share of this sector of the vegetable market does not reach 0.5% in gross fees. The range of uncommon crops in the markets of Ukraine, especially supermarkets is provided mainly through imports. The scientific novelty is that to study the attitude of consumers to green vegetable products, a sociological survey was conducted and an analysis of the main factors influencing the purchase of this type of product. It was found that when choosing a point of sale, such factors as location, service, quality of service in places of purchase of green products, range, staff qualifications, etc. have a great influence on consumer behavior. The advantages and disadvantages of individual sales channels of greenery are analyzed. The advantages include: convenience, territorial proximity, wide range, price flexibility, product quality, its freshness, etc. Neoliks include: lack of certificates for products, narrow range and unsatisfactory sanitary conditions of trade places. It is found out that at formation of effective model of innovative development of branch of vegetable growing it is necessary to apply the newest methods of selection, new grades and hybrids which have high productive potential, to introduce scientifically proved systems of cultivation and seed production, to master new segments of green cultures and microgreens. The article identifies the main problems and identifies priority areas for the development of the market of green crops for the future.

Introduction: greenhouses need microclimate control systems to grow agricultural crops. The method of carbon dioxide injection, which is currently used by agricultural companies, causes particular problems. Co-generation power plants may boost the greenhouse efficiency, as they are capable of producing electric energy, heat and cold, as well as carbon dioxide designated for greenhouse plants.Methods: the co-authors provide their estimates of the future gas/electricity rates growth in the short term; they have made a breakdown of the costs of greenhouse products, and they have also compiled the diagrams describing electricity consumption in case of traditional and non-traditional patterns of power supply; they also provide a power distribution pattern typical for greenhouse businesses, as well as the structure and the principle of operation of a co-generation unit used by a greenhouse facility.Results and discussion: the co-authors highlight the strengths of co-generation units used by greenhouse facilities. They have also identified the biological features of carbon dioxide generation and consumption, and they have listed the consequences of using carbon dioxide to enrich vegetable crops.Conclusion: the co-authors have formulated the expediency of using co-generation power plants as part of power generation facilities that serve greenhouses.
