Abstract

Time of weed control and fertilizer application usually decide the profitability of crop production. The effects of nitrogen and weed interference duration on yield and yield components of corn was studied in the Research Station of University of Tabriz, Iran, in 2009. The experiments were carried out as split-plot, based on randomized complete block design with three replications.
