Review of experiments on reduced cultivation and direct drilling in the United Kingdom,1957–1974

Abstract

In early experiments, before 1970, average yields of winter wheat and spring barley after direct drilling or shallow cultivation were less than after ploughing, but, in later experiments, there was little yield difference compared with ploughing. Direct drilling of forage brassicae and oilseed rape has become commercially important in the United Kingdom without much experimental work.
