Abstract
Istraživanja utjecaja različitih konzervacijskih sustava obrade tla i različitih gnojidbenih doza dušika na urod zrna kukuruza obavljena su tijekom tehnološke 2012./2013. godine, na hidromorfnom tipu tla, na lokaciji Čačinci (GPS: Long. 17.86336 E; Lat. 45.61316 N). Istraživani sustavi obrade tla bili su slijedeći: OR–konvencionalna obrada tla i četiri konzervacijska sustava: PO–podrivanje; RA–rahljenje; TA–tanjuranje i DS–direktna sjetva. Gnojidbeni tretmani bili su slijedeći: N1–gnojidba umanjena za 50% u odnosu na gnojidbenu preporuku; N2–gnojidba prema gnojidbenoj preporuci i N3–gnojidba uvećana za 50 % u odnosu na gnojidbenu preporuku. Temeljem provedenih istraživanja utvrđeno je kako je visina poljoprivrednog i biološkog prinosa bila pod statistički opravdanim utjecajem sustava obrade tla kao i razine gnojidbe dušikom. Najveći poljoprivredni i biološki prinosi kukuruza zabilježeni su na varijanti konvencionalne obrade tla (10,23 t/ha i 42,96 t/ha), te na gnojidbenom tretmanu prema gnojidbenoj preporuci (9,89 t/ha i 38,33 t/ha). Sustav obrade tla i gnojidbe dušikom nisu statistički opravdano utjecali na visinu žetvenog indeksa kukuruza, a najmanji žetveni indeks zabilježen je na konvencionalnoj obradi tla.

Investigation of influence of different soil tillage treatments and different nitrogen doses fertilization on maize yield were conducted during technological 2012/2013. year, on the hydromorphic soil type, on the location Čačinci (GPS: Long. 17.86336 E; Lat. 45.61316 N). Investigated tillage systems were as follows: OR-conventional soil tillage and four conservation systems: PO-subsoiling, RA-chiseling, TA-diskharrowing and DS-direct seeding. Fertilazer treatments were as follows: N1-fertilization 50% less than fertilizer recommendation, N2-fertilization according fertilizer recommendation and N3-fertilization 50% more than fertilazer recommendation. Scientific research has shown that the amount of agricultural and biological yield was under significant influence of soil tillage systems as well as the level of nitrogen fertilization. Largest agricultural and biological maize yields were registered in the variant of conventional soil tillage (10.23 t / ha and 42.96 t / ha), and on the fertilization treatment according to fertilization recommendation (9.89 t/ha and 38.33 t/ha). The system of soil tillage and nitrogen fertilization were not statistically significant affected the harvest index of maize, and the lowest harvest index was registred in conventional soil tillage.
