Results of small-plot trials with NS sunflower hybrids and recommendation for the 2008 planting season

Abstract

The objective of this study was the evaluation of NS sunflower hybrids on the basis of the results of seed yield, oil content and oil yield obtained in a network of small-plot trials organized in Vojvodina and central Serbia in 2007, as sowing recommendations for the 2008 planting season. Twenty NS sunflower hybrids in 12 locations (in Vojvodina and 4 in central Serbia) were included in small plot-trials. The highest seed yield in Vojvodina was achieved by the hybrid Duško (3.34 t/ha), followed by Velja, Šumadinac and Kazanova. The hybrid NS-H-45 (2.02 t/ha) achieved highest seed yield in central Serbia. Pobednik (Vojvodina), NS-H-111 (both regions) and Somborac (Vojvodina) had the oil content over 48%. The hybrids Šumadinac, Baća and NS-H-111 produced the highest oil yield in Vojvodina (over 1.5 t/ha). In the three-year trials in Vojvodina, the hybrids Sremac (2.96 t/ha), Šumadinac (2.81 t/ha) and NS-H-111 (2.74 t/ha) produced the highest seed yields.

Cilj rada je bio da se ispitaju proizvodne osobine novosadskih hibrida suncokreta na osnovu rezultata koje su ostvarili za prinos semena, sadržaj ulja i prinos ulja u mreži mikroogleda u Vojvodini i centralnoj Srbiji u toku 2007, kao i da se da preporuka sortimenta za 2008. godinu. U ispitivanje je uključeno 20 hibrida i 12 lokaliteta u Vojvodini i 4 u centralnoj Srbiji. Prinos semena, sadržaj ulja i prinos ulja su se u mreži mikroogleda značajno razlikovali u oba ispitivana regiona. U Vojvodini, najveći prosečan prinos semena ostvario je hibrid Duško (3,34 t/ha). Visok prinos semena utvrđen je kod hibrida Velja, Šumadinac i Kazanova. Najveći prosečan prinos semena u centralnoj Srbiji ostvario je hibrid NS-H-45 (2,02 t/ha). Sadržaj ulja veći od 48 % imala su tri hibrida i to Pobednik (Vojvodina), NS-H-111 (oba regiona) i Somborac (Vojvodina). Na teritoriji Vojvodine najveće vrednosti prinosa ulja postigli su Šumadinac, Baća i NS-H-111 i to u proseku veće od 1,50 t/ha. U trogodišnjim ispitivanjima u Vojvodini najveći prosečan prinos semena su postigli hibridi Sremac (2,96 t/ha), Šumadinac (2,81 t/ha) i NS-H-111 (2,74 t/ha).
