Abstract

Available climate and natural resources are allowing the successful vegetable production at wider territory of the Republic of Serbia. Production lines are organized at open field or in protected areas (greenhouses), and usually involve the use of agro technical measure of irrigation. Technologicaltechnical complexity and much higher requirements for production intensity, more often contribute to a higher competitiveness of agricultural holdings dominantly oriented to the production of vegetables. In paper are presented the comparative results of field researches carried out in September and October 2015, and during the period August - November 2016. In last research, besides mobile robotic solar generator, in real terms was partially tested the use of mobile wind generator. Also, during the research are processed the data collected from the members of family agricultural holdings focused to the vegetable production, located in the Glogonj village at territory of the Pančevo city (within the wider area of the Upper Danube Basin) and in the Veliko Selo village at the territory of the Belgrade city (within the area of the Middle Danube Basin). For the research purposes, in accordance with the previously made agreement with holdings’ members, observed holdings are marked with A and B. On the holding A, in the structure of variable costs, costs of irrigation are quite an equable (in the open field: from 357,72 to 364,29 EUR/ha, or in a greenhouse: from 378,50 to 554,00 EUR/ha). On the holding B, in the structure of variable costs, depending the production area costs of irrigation are visibly different (in the open field: from 85,00 to 341,50 EUR/ha, or in a greenhouse: from 2.550,00 to 3.278,00 EUR/ha). In order to increase economic effects in vegetable production, there is a possibility of used energy conversion (gasoline, diesel and electric power) into the cheaper and environmentally more acceptable solution (solar and wind energy).
