ECONOMIC ASPECTS ON SOYBEAN PRODUCTION IN EAST CROATIA

Tijekom dvogodišnjeg razdoblja (2004. i 2005. godine) obavljeno je istraživanje o visini prinosa i ekonomskoj isplativosti proizvodnje tri rane sorte soje (Dubravka 0, Marija 00 i Danica 000) različitih grupa dozrijevanja. Pokusi su postavljeni po split-plot shemi na poljima Zavoda za sjemenarstvo i rasadničarstvo iz Osijeka, Kutjevo d.d. i PPK Nova Gradiška uz primjenu standardne agrotehnike za soju. Jaz koji nastaje porastom broja stanovnika i istovremenim smanjenjem poljoprivrednih površina iz godine u godinu sve je veći, a soja zbog velikog postotka bjelančevina (od 35-50%) i ulja (od 18-24%) preuzima vodeće mjesto u proizvodnji i ishrani čovječanstva. Soja zbog naknadne i postrne sjetve postaje zanimljiva poljoprivrednim proizvođačima diljem svijeta. Uzimajući u obzir agrotehničke mjere koje se koriste, uz pomoć tablica i grafikona dana je analiza čimbenika i usporedba isplativosti proizvodnje pojedine sorte soje u Hrvatskoj na površini preko tri hektara, kako bi se odredila najpogodnija sorta za domaću poljoprivrednu proizvodnju.During the two vegetation years (2004 and 2005) an examination was conducted on influence of three early breeds of soybean (Dubravka 0, Marija 00 and Danica 000) belonging to different groups of ripening in terms of level of crop yield and cost effectiveness. The tests were undertaken by split-plot scheme on the crop fields originated from Institution for seed and seedlings Osijek, Kutjevo d.d. and PPK Nova Gradiška using standardized agro measures valid for soybean in The Republic of Croatia. The difference between increase of the number of inhabitants and decrease in the crop fields area has risen significantly. Soybean, because of its high percentage of proteins (35-50%) and oil (18-24%), slightly for sure overtakes the first position in agricultural production and nutrition of mankind. Soybean is becoming more and more interesting to producers worldwide because of its rich seeding capability. Taking into account the agricultural measures used the analysis and comparison of production effectiveness between each breed of soybean in Croatian on the area more than three ha are presented in tables and graphs. In this way the best breed can be ultimately determined for domestic farm production
