The first experiment was conducted in 2005 and repeated in 2006 season, whereas, the second one was carried out for one season of 2007. Both experiments aimed to study the efficiency of certain herbicides for weed control and their impact on productivity of 1hree soybean [Glycine max (L.) Merr.] cuItivars. Six herbicides were tested in the two experiments, individually or in combinations; i.e., oxadiargyl, butralin and metribuzin (pre-emergence) and bentazon, clethodim and tepraloxydim (post-emergence), plus hand hoeing twice and unweeded control. A split-plot design, with three replications, was used in the two experiments, where the weed control treatments were arranged in the main plots, while, the soybean cultivars were assigned to the sub-plots UR - http://nile.enal.sci.eg/EALE/2011/AJARX/5611/1/39.pdf ER -
