MARKED differences in winter barley performances across the regions feature in first results from Arable Research Centres.
Director Mike Carver believes poor rooting caused by the wet autumn and spring is the reason. Average yields are 9.9t/ha (4t/acre) on medium soils to only 5.5t/ha (2.2t/acre) on thinner land.
Six-row types have done well in all regions. But two-rows Fanfare, Regina, Vertige, Pearl and Heligan have turned in significantly different performances. "Results will have to be carefully interpreted." *
