Exploitation of tractors in agricultural production in greenhouses

U radu je prikazana eksploatacija traktora u poljoprivrednoj proizvodnji u zaštićenim prostorima. Traktor je osnovno pokretno energetsko sredstvo u poljoprivredi, koje može vući ili nositi priključne poljoprivredne strojeve i oruđa, u cilju izvođenja mehaniziranih radnih operacija. Proizvodnja u zaštićenim prostorima je važna i brzo rastuća komponenta poljoprivredne industrije razvijenih zemalja. U Republici Hrvatskoj ova je proizvodnja još uvijek u fazi razvoja. Hrvatska ima velike potencijale za proizvodnju povrća u zaštićenom prostoru, ali ih dovoljno ne koristi. Razlog tome su visoka cijena repromaterijala, nepovoljni krediti, visoki troškovi proizvodnje, ne konkurentnost na tržištu, usitnjenost poljoprivrednih parcela.The paper is presents exploitation of tractors in agricultural production in greenhouses. Tractor is the basic movable energy tool in agriculture, can tow or carry connecting agricultural machines and tool's in order to perform mechanized operations. Production in greenhouses is an very important and rapidly growing component of agricultural industry of developed countries. In Croatia this production is still in the development phase. Croatia has great potential for vegatable production in greenhouses, but it not use them enough. Reason for this is really high price's of the raw materials, unfavorable loan's, high production cost's, no market competitiveness and fragmentation of agricultural parcels
