Sunflower row configuration × population × hybrid – Pine Ridge 2014–15

Abstract

Key findings • Yields from the 35,000 plants/ha and 45,000 plants/ha target plant populations were significantly higher than the 25,000 plants/ha treatment (by 0.52–0.56 t/ha). Plant population did not affect oil content. • The solid 75 cm treatment achieved a yield significantly higher than the solid 100 cm and superwide (150 cm) configurations. Varying row configuration did not affect oil content. • Ausigold 62 and Hyoleic 41 produced higher yields than the experimental sunflower hybrid. Ausigold 62 had significantly higher oil content than the other two hybrids evaluated.
