dc.description.abstractThe study presents effects of seven sowing densities (G1 - 40,816, G2 50,125, G3 - 59,523, G4 - 69,686, G5 - 79,365, G6 - 89,286 and G7 - 98,522 plants ha-1) on grain yield of six ZP maize hybrids (ZP 360, ZP 539, ZP 580 ZP 680, ZP 677, ZP 704). The trial was performed on chernozem in experimental fields of the Maize Research Institute, Zemun Polje in the period 1998-2000. A 4-replicate three-year two-factorial trial was set up according to the split-plot method under rainfed conditions. Obtained results indicate to statistically very significant differences in grain yields over investigation years and among maize hybrids. The lowest average yield (6.05 t ha-1), with statistically very significant differences in relation to other two years (1988 - 11.52 t ha-1, 1999 - 11.35 t ha-1) was achieved in the year with the smallest amount of precipitation during the growing season (2000). The highest yields were obtained at different densities in dependence on weather conditions during the growing season and maize hybrids. In relatively favorable years the highest yields of the studied hybrids were obtained in the following densities: ZP 360 - 80-90,000 plants ha-1; ZP 539 -80.000 plants ha-1; ZP 580 - 70-80,000 plants ha-1; ZP 633 - 70,000 plants ha-1; ZP 677 - 60-70,000 plants ha-1; ZP 704 70-80,000 plants ha-1. The following densities were the most favorable under conditions of pronounced water deficit during the growing period: ZP 360 - 70,000 plants ha-1; ZP 539 - 60-70,000 plants ha-1; ZP 580 - 50-60,000 plants ha-1; ZP 633 - 70,000 plants ha-1; ZP 677 - 50-60,000 plants ha-1; ZP 704 - 60-70,000 plants ha-1.en
dc.description.abstractU radu su prikazani rezultati proučavanja uticaja sedam gustina setve ( G1 40.816 bilj/ha, G2 -50.125 bilj/ha, G3 - 59.523 bilj/ha, G4 - 69.686 bilj/ha, G5 -79.365 bilj/ha, G6 - 89.286 bilj/ha, G7 - 98.522 bilj/ha) na prinos zrna šest ZP hibrida kukuruza (ZP 360, ZP 539, ZP 580, ZP 680, ZP 677, ZP 704). Trogodišnja ispitivanja (1998-2000) obavljena su u agroekološkim uslovima Zemun Polja u prirodnom vodnom režimu. Dobijeni rezultati pokazuju da su, u godinama proučavanja, između ispitivanih hibrida i gustina ostvarene statistički veoma značajne razlike prinosa zrna kukuruza. U godini sa najmanje padavina tokom vegetacije (2000), ostvareni su najniži prosečni prinosi (6,05 t/ha), sa statistički veoma značajnom razlikom u odnosu na druge dve godine (1988. - 11,52 t/ha, 1999. - 11,35 t/ha). U zavisnosti od meteoroloških uslova tokom vegetacije najviši prinosi ostvareni su različitim gustinama setve. U relativno povoljnijim godinama za gajenje kukuruza ispitivani hibridi ostvarili su najbolje rezultate prinosa u sledećim gustinama: ZP 360 - 80-90.000 bilj/ha, ZP 539 - 80.000 bilj/ha ZP 580 -70-80.000 bilj/ha, ZP 633 -70.000 bilj/ha, ZP 677 - 60-70.000 bilj/ha, ZP 704 - 70-80.000 bilj/ha. U uslovima izrazitog deficita vode tokom vegetacije najpovoljnije gustine su: ZP 360 -70.000 bilj/ha, ZP 539 60-70.000 bilj/ha, ZP 580 - 50-60.000 bilj/ha, ZP 633 - 70.000 bilj/ha, ZP 677 -50-60.000 bilj/ha, ZP 704 - 60-70.000 bilj/ha.sr
