Winter barley nitrogen trials prompt rate rethink

摘要

A rethink of fertiliser nitrogen recommendations for winter barley crops could be on the horizon with GrowHow suggesting changes to the timings and amount applied, based on three years of trials. Work carried out by ADAS at two sites on GrowHow's behalf suggests that applying as much as half of the crop's nitrogen requirement in late February increases both grain and straw yields, while reducing grain nitrogen levels.
