Abstract
Istraživanje je provedeno na proizvodnoj površini u vlasništvu Obiteljskog poljoprivrednog gospodarstva Nikola Severović u Radeljevom Selu u Koprivničko-križevačkoj županiji u 2012. godini. Ciljevi istraživanja obuhvatili su utvrđivanje optimalne količine osnovnih biljnih hraniva (N, P2O5 i K2O) za ostvarenje održivog prinosa zrna kukuruza na istraživanom području te utvrđivanje prinosa i vlage u zrnu kukuruza za svaku varijantu gnojidbe. Pokus je postavljen s tri različite varijante gnojidbe i kontroli bez gnojidbe po metodi slučajnog bloknog rasporeda. Uzgajani hibrid kukuruza bio je Pioneer PR37NO1. Na varijanti gnojidbe 1 je primijenjeno 175 kg/ha N, 194 kg/ha P2O5 i 210 kg/ha K2O. Varijanta 2 obuhvatila je gnojidbu s 221 kg/ha N, 198 kg/ha P2O5 i 180 kg/ha K2O. Kontrolna varijanta, bez primjene gnojiva bila je varijanta 3. Na varijanti 4 gnojidba je obavljena s 150 kg/ha N, 189 kg/ha P2O5 i 210 kg/ha K2O. Istraživanje je provedeno u klimatski nepovoljnoj godini za uzgoj kukuruza. Ukupna količina oborina na istraživanom području u vegetacijskom razdoblju 2012. godine iznosila je 338,9 mm, a u prethodnom promatranom višegodišnjem razdoblju 537,6 mm. Istovremeno su utvrđene više srednje mjesečne temperature zraka u usporedbi s promatranim prethodnim višegodišnjim razdobljem. Najveći prinos zrna kukuruza ostvaren je na varijanti gnojidbe 1, gdje je primijenjeno 175 kg/ha N, 194 kg/ha P2O5 i 210 kg/ha K2O. Na Obiteljskom poljoprivrednom gospodarstvu Severović u 2012. godini utvrđeni su niži prinosi merkantilnog zrna kukuruza od realno moguće ostvarivih, uvažavajući potencijal rodnosti uzgajanog hibrida i primijenjenu gnojidbu. U klimatski nepovoljnoj godini, za ostvarenje najvišeg prinosa zrna kukuruza preporuča se gnojidba s 175 kg/ha N, 194 kg/ha P2O5 i 210 kg/ha K2O. Gnojiva rasporediti na način da se u jesen zaore 100 kg/ha MAP-a i 700 kg/ha NPK 7:20:30, a predsjetveno zatanjurati 250 kg/ha UREA.
Abstract (croatian)
The study was conducted on a production surface of the family farm (OPG) Nikola Severovic in Radeljevo Selo in Koprivnicko-krizevacka county in 2012. Research objectives included the determination of the optimal quantities of basic plant nutrients (N, P2O5 and K2O) for sustainable corn grain yield in the study area and to determine the yield and corn grain moisture for each variant of fertilization. The experiment was set up with three different variants of fertilization and control without fertilization by randomized block design. Grown corn hybrid was Pioneer PR37NO1. For fertilizing variant 1, 175 kg/ha N, 194 kg/ha P2O5 and 210 kg/ha of K2O was applied. Variant 2 included fertilization with 221 kg/ha N, 198 kg/ha P2O5 and 180 kg/ha of K2O. The control treatment, without the use of fertilizers was variant 3. Variant 4 fertilization was carried out with 150 kg/ha N, 189 kg/ha P2O5 and 210 kg/ha of K2O. The study was conducted in a climate unfavorable year for corn growing. The total rainfall in the study area during the vegetation period of 2012 was 338.9 mm, while in the previous observed multi-year period it was 537.6 mm. At the same time, higher mean monthly air temperatures were determined in comparison to the previous observed multi-year period. The highest corn grain yield was achieved on fertilization variant 1, where 175 kg/ha N, 194 kg/ha P2O5 and 210 kg/ha of K2O was applied. On family farm Severovic established yields of mercantile corn grain in 2012 were lower than real possible achievable, taking into account the yield potential of grown hybrid and applied fertilization. In climatically unfavorable year, to achieve the highest grain yield, fertilization with 175 kg/ha N, 194 kg/ha P2O5 and 210 kg/ha of K2O is recommended. Amount of 100 kg/ha of MAP and 700 kg/ha NPK 7:20:30 should be ploughed in autumn and 250 kg/ha of UREA should be incorporated into soil by disc harrow before sowing.
