AB  - Spinach is very common in the human nutrition due to its high nutritive value. It is commonly grown in the greenhouses. In region of Serbia, spinach is commonly grown in the tunnel structure greenhouses, covered with single or double PE folia without additional heating. The aim of the research was to see if different greenhouse construction types influence the microclimatic parameters in the spinach production and to see if choosing the certain greenhouse construction type can improve an overall production conditions resulting in higher spinach yield, lower energy consumption and higher energy productivity. Spinach production was tracked in the three different types of greenhouses. The round-shaped greenhouse has its base diameter of 7 m while tunnel type greenhouse was 5.5 m wide and 24 m long. Single span greenhouse was 10 m wide and 50 m long. All greenhouses were covered with PE UV IR 180 mu m folia. Results show that production conditions are dependent on type of greenhouse construction. During the winter spinach production solar radiation energy losses in the tunnel structure were 29.38% while the round-shaped greenhouse was losing 19.51% of the solar radiation energy. Losses in the single-span greenhouse were 12% in the morning hours and 43% during the day. During the day air temperatures in the greenhouses were higher. In the round-shaped and tunnel structure greenhouse this temperature difference lower than 1 degrees C and are not considered important for the plants. In the case of single-span greenhouse inside-outside differences were 2.52 degrees C up to 16.26 degrees C.

AB  - Agricultural production in greenhouse represents the most intensive form of agricultural production. This is a very complex production system that needs to be well maintained and with great attention. The aim of this paper is to present preliminary research results on raspberry production in greenhouse and in the open field regarding the microclimatic production conditions. In this paper, results on microclimatic production conditions in the tunnel structure greenhouse and in the open filed are presented. The raspberry variety Heritage (Rubus Heritage) was grown in the 7 x 24 m tunnel greenhouse covered with the single PE folia and in the open filed. Results show that production conditions in the greenhouse enable prolonged harvesting (September, October) till the first frosts. Air temperature, air relative humidity and solar radiation were measured and analyzed. Temperature inside the greenhouse varied along the greenhouse and during the day but the variations were not significant enabling the uniform production conditions during the day. Air relative humidity did not show significant variation concerning the open field and greenhouse production. Solar radiation showed high losses in the morning hours. Only 25.82 % of solar energy was available to the plants.

AB  - In this paper a way of improving the greenhouse production on the small scale or family farms is presented. A new type of round shape greenhouse construction is introduced that should lead to more energy, economy and ecology efficient vegetable production. Energy efficiency of the spinach and tomato production in the round greenhouse was compared with common tunnel structure. Results show that, regardless the production surface restrictions, with this type of greenhouse construction financial and energy savings are possible together with the minimization of the plant protection chemical usage. If organic fertilizer is used this type of construction can lead to improved food safety production.
