Abstract

Iako je krumpir jedna od četiri strateški najvažnijih namirnica u svijetu, Hrvatska ga još uvijek ne proizvodi dovoljno za vlastite potrebe. Kod nas se krumpir najviše uzgaja u Slavoniji i Međimurju gdje je zadnjih nekoliko godina prinos u porastu, ali još uvijek dosta ispod prosjeka zapadnoeuropskih zemalja. Neki od glavnih razloga nekonkurentnosti i neisplativosti na Hrvatskom tržištu su: visoke cijene repromaterijala, velika ulaganja u modernizaciju mehanizacije te trgovački lobi koji ruši cijenu domaćim proizvođačima. Kako bi se troškovi proizvodnje sveli na minimum potrebna je suvremena mehanizacija koja smanjuje vrijeme rada, a povećava radni učinak i prihode.
U radu su prikazani rezultati terenskog mjerenja radnih učinaka i utrošci goriva kod različitih izvedbi kombajna za vađenje krumpira. Analizirani su troškovi vađenja krumpira, a oni su se odnosili na troškove goriva i radnika, bez amortizacije strojeva.

Abstract (english)

Although the potato is one of four strategically most important foods in the world, Croatia it still does not produce enough for their own needs. In our country, the potato is mostly grown in Slavonia and Međimurje where in the last few years the yield is rising, but still well below the average for Western European countries. Some of the main reasons for the lack of competitiveness and the unprofitability of the Croatian market are: high prices of raw materials, large investments in modern equipment and trade lobby that crashes cost domestic producers. To reduce costs to minimum it is necessary to invest in modern machinerythat reduces the operating time, and increase productivity and revenue.
The paper presents the results of field measurements of performance data and fuel consumption at the different designs of the combine harvester for potato. We analyzed the cost of harvesting the potatoes, but they are related to costs of fuel and workers, without depreciation of machinery.
