The influence of cropping intensity on productivity and weediness of winter wheat and spring barley

Abstract

This paper presents the summarized investigations results of winter wheat and spring barley yield and weediness under the condition of organic and intensive cropping systems in limed CMg-n-w-dy as well as LVa-gld-w soils. The yield of winter wheat grain increased up by 44-62%, the one of spring barley increased by 94-106%. Application of intensive cropping system reduced the crop weediness. Under the conditions of organic cropping system short-lived dicotyledonus weeds were spread more widely while under the conditions of intensive cropping system perennial monocotyledonus weeds were observed more often
