Sorghum in the western zone – Row Configuration x Population x Hybrid – Garah 2013

Abstract

Key findings • Sorghum grain yield decreased as row spacing increased at this site under 2012–13 seasonal conditions. The double skip treatment yielded close to half that of the solid plant treatment. The 2.0 m super wide treatment was also significantly lower yielding than the solid and single skip treatments. • There was no significant difference in hybrid sorghum performance at this site. • The 15,000 plants/ha plant population yielded significantly less than the 30 or 50,000 plants/ha treatments. • Finishing soil water data showed there was more water remaining in the wider row configurations (double skip and super wide) in the mid row area when compared to the solid and single skip treatments.
