Productivity of NS sunflower hybrids in small-plot trials in Serbia in 2010

Abstract

The objective of this study was the evaluation of NS sunflower hybrids on the basis of the results of seed yield, seed oil content and oil yield obtained in a network of small-plot trials in Vojvodina and central Serbia in 2010, as well as recommendations for the sowing season 2011. Seed yield, seed oil content and oil yield were significantly different in small-plot trials in the investigated regions. In Vojvodina, the highest average seed yield was produced by Duško (3.08 t ha-1), Sremac (2.98 t ha-1), Orfej (2.97 t ha-1) Velja (2.93 t ha-1) and NS-H-111 (2.92 t ha-1). In the region of central Serbia, the highest seed yield was achieved by the hybrids NS-H-111 (2.97 t ha-1) and Duško (2.87 t ha-1). Hybrid Baća showed the highest average seed oil content both in the region of Vojvodina (48.54%) and central Serbia (48.80%). The highest average oil yield (over 1.30 t ha-1) was produced by Duško, Bačvanin and NS-H-111 in the Vojvodina region, and in central Serbia oil yield (over 1.30 t ha-1) by NS-H-111, Oskar and Novosađanin. In the three-year trials in Vojvodina four hybrids (Duško, Sremac, Velja and NS-H-111) showed seed yield over general mean. The highest seed yield was reached by hybrid Duško (3.54 t ha-1).
