The present research included data from 3-year field experiments ( 2005 - 2007) with cotton cultivate Avangard - 264., including variants with different density of the Amaranthus retroflexus L. It was ascertained that with increasing the weed density the raw cotton yield decreased. During the process of work, the classic variation correlation and regression analyses were used to figure out and organise all the facts and information.
