Costs and effects of irrigation systems in agricultural production

Cilj ovog rada je opisati sustave navodnjavanja te ispitati kako oni utječu na poljoprivrednu proizvodnju i koliko su ekonomski značajni. Od posebne je važnosti odrediti kolike troškove zahtijeva sam sustav navodnjavanja i potrebna oprema. Veliki proizvođači ulažu mnogo u svoju proizvodnju kako bi imali što veće prinose, a samim tim i veći prihod. U radu je temeljem analitičke kalkulacije utvrđen ekonomski učinak navodnjavanja na primjeru proizvodnje kukuruza, rajčice i jabuke. Prema provedenim ekonomskim analizama utvrđeno je da se navodnjavanje najviše isplati kod proizvodnje jabuka i rajčica. Analize su pokazale povoljan ekonomski učinak na samu proizvodnju. Najviša rentabilnost i ekonomičnost prema izračunima ostvarena je kod proizvodnje rajčica uz navodnjavanje.The aim of this paper is to describe irrigation systems and examine how they affect agricultural production and how economically significant they are. It is of particular importance to determine the costs of the irrigation system itself and the necessary equipment. Large producers invest a lot in their production in order to have the highest possible yields, and therefore a higher income. In the paper, based on analytical calculations, the economic effect of irrigation was determined on the example of corn, tomato and apple production. According to the conducted economic analyses, it was determined that irrigation is most profitable for the production of apples and tomatoes. The analyzes showed a favorable economic effect on the production itself. The highest profitability and economy, according to the calculations, was achieved in the production of tomatoes with irrigation
