Investigation of some problems of direct drilling in Czechoslovakia

Abstract

Experiments in Czechoslovakia with direct-drilling techniques have shown that the influence of the previous crop is considerable. Difficulties arise principally where cereals, particularly winter wheat, follow cereals, and extra nitrogen is necessary to ensure yields comparable with those following traditional cultivations. Winter wheat and barley can be successfully direct-drilled after sugar beet, potato, legumes, rape and maize, and other applications of the technique show promise.
