Extract

Investigations of the competitive effects of Setaria lutescens (Weigel) F. T. Hubb. (yellow foxtail) on corn have dealt primarily with the factors of crop and weed populations, nitrogen fertilizer applications, duration of the period of competition and the amount and distribution of seasonal rainfall. Differences in the competitive efficiencies of various crops and weeds have been demonstrated under various production conditions, but relatively less is known regarding competitive efficiencies among varieties of given crop species. Working under the dryland conditions of Western Canada, Pavlychenko and Harrington compared the competitive efficiencies of several small grains. They ranked barley as the most efficient competitor of weeds, followed by spring rye, wheat and oats in that order. The importance of fertilizer applications in increasing the competitive efficiency of crops has been investigated widely. Previous studies with corn and soybeans have demonstrated some aspects of the role of soil moisture in determining the nature and extent of weed competition in these crops.
