dc.description.abstractThe results obtained in the ten-year trial (2000-2009) carried out under agro-ecological conditions of Zemun Polje are presented in this study. The objective was to determine effects of soil water regime (A) and the fertilizer rates (B) on the yield of maize directly sown in chernozem. The trial was set up according to the block design under conditions of rain fed and irrigation with the three NPK levels: B1 - Ø; B2 - 150 kg nitrogen ha-1, 105 kg phosphorus ha-1 and 75 kg potassium ha-1; B3 - 300 kg nitrogen ha-1, 210 kg phosphorus ha-1 and 150 kg potassium ha-1. Maize was sown with the John Deere-7200 MaxEmerge 2 planter. Results were processed by the factorial analysis of variance and the LSD test, while the dependence of the yield on the water regime was established by the regression analysis. Obtained results showed that the formation of yield had been significantly affected by the water regime and fertilizing. The average yield amounted to 7.25 t ha-1 and 9.31 t ha-1 under rain fed and irrigation conditions, respectively. The following yields were obtained on the average over fertilizing variants: B1- 6.46 t ha-1, B2- 8.74 t ha-1 and B3- 9.64 t ha-1. The yield of 7.74 t ha-1 can be expected in the variant B1, if 450 mm of water enters the soil surface during the growing season. With 20 mm more water the yields expected in variants B2 and B3 could be 10.60 t ha-1 and 11.70 t ha-1, respectively.en
dc.description.abstractU radu su prikazani rezultati desetogodišnjeg ogleda (2000-2009) izvedenog u agroekološkim uslovima Zemun Polja. Cilj je bio da se utvrdi uticaj vodnog režima zemljišta (A) i nivoa đubrenja (B) na prinos kukuruza, koji je sejan na černozemu direktno u strnište. Ogled je bio postavljen po metodi blok sistema, u prirodnom i irigacionom vodnom režimu, u varijantama primene sledećih količina NPK hraniva: B1- Ø kg ha-1; B2 - 150 kg N ha-1, 105 kg P ha-1 i 75 kg K ha-1; B3- 300 kg N ha-1, 210 kg P ha-1 i 150 kg K ha-1. Setva hibrida kukuruza ZP 704 je obavljana sejalicom John Deer- 7200 MaxEmerge 2. Rezultati prinosa su obrađeni analizom varijanse i LSD testom, a regresionom analizom utvrđena je zavisnost prinosa i količine vode. Rezultati pokazuju da su vodni režim zemljišta i đubrenje veoma značajno uticali na formiranje prinosa kukuruza. U prirodnom vodnom režimu ostvaren je prosečan prinos 7,25 t ha-1, a u irigacionom 9,31 t ha-1. U proseku, po varijantama đubrenja dobijene su sledeće vrednosti: B1- 6,46 t ha-1, B2- 8,74 t ha-1, B3-9,64 t ha-1. U varijanti B1 može se očekivati maksimalni prinos 7,74 t ha-1, ako tokom vegetacionog perioda na površinu zemljišta dospe 450 mm vode. Sa 20 mm više vode u varijantama B2 i B3 mogu se očekivati prinosi 10,60 t ha-1 i 11,70 t ha-1.sr
