Abstract
Provedena su istraživanja utjecaja različitih varijanata obrade tla i različitih gnojidbenih doza dušika na visinu prinosa kukuruza, na automorfnom tipu tla, na lokaciji u blizini Magadenovca. Istraživanjima je obuhvaćeno pet varijanata obrade tla: OR–konvencionalna obrada tla; PO–podrivanje; RA–rahljenje; TA–tanjuranje i DS–direktna sjetva, a gnojidba dušikom je primijenjena u tri razine: 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. Dobivenim podacima je utvrđeno kako su varijante obrade tla i varijante gnojidbe dušikom značajno utjecale na visinu poljoprivrednog prinosa (zrno) i biološkog prinosa kukuruza. Najveći poljoprivredni i biološki prinosi kukuruza ostvareni su na varijanti podrivanja (poljoprivredni prinos 15,24 t/ha, biološki prinos 27,03 t/ha) i na gnojidbenom tretmanu izračunatom prema preporuci (poljoprivredni prinos 14,57 t/ha, biološki prinos 26,69 t/ha). Žetveni indeks je u prosjeku iznosio 26,6 % i nije bio pod utjecajem niti obrade tla niti gnojidbe dušikom.
Abstract (english)
Investigation of influence of different soil tillage treatments and different nitrogen doses fertilization on maize yield were conducted in 2013 year on automorphic soil tipe near Magadenovac. The field experiments were includes five variants of soil tillage: OR-conventional (plowing), PO-subsoiling, RA-chiseling, TA-diskharrowing and DT-no tillage and nitrogen fertilization were applied in three levels: N1-fertilization 50% less than fertilizer recommendation, N2-fertilization according fertilizer recommendation and N3-fertilization 50% more than fertilizer recommendation. According results, different soil tillage treatments and different nitrogen fertilization treatments had significantly influence on agricultural maize yield and biological maize yield. Largest agricultural and biological maize yield achieved on treatment PO-subsoiling (agricultural yield 15.24 t/ha, biological yield 27.03 t/ha) and on N2 fertilization treatment (agricultural yield 14.57 t/ha, biological yield 26.69 t/ha). Harvest index in average amounted 26.6%, and was not statistically influenced by tillage and nitrogen fertilization.
