Abstract: Two field experiments were carried out at El-Ismailia Agricultural Research Station, Agricultural Research Center during 2007 and 2008 successive summer seasons in a sandy soil under sprinkler irrigation system to study the effect of the integration between hand hoeing and some chemical weed control treatments on the dry weight (g/m 2 ) of annual weeds, growth characters, yield and its components, seed oil percentage of peanut ( Arachis hypogaea L.).Treatments were arranged in a split plots design with four replicates.The results revealed that one hand hoeing combined to all chemical weed control treatments decreased the dry weight of annual weeds (g/m 2 ) at 75 and 105 days after sowing in both seasons and increased all growth characters, yield components, pod yield (ardab/fed.) and straw yield (ton/fed.) of peanut as compared with chemical weed control treatments alone.Clethodim herbicide caused the highest reduction in dry weight of annual weeds i.e. 99.2 and 85% at 75 days after sowing in 2007 and 2008 seasons, respectively as compared with unweeded check.Applying clethodim or butralin had the superiority in depressing broad leaved weeds , while fluazifop-butyl came in the second rank.Concerning grassy weeds, bentazon or clethodim was superior in suppressing them .Adding hoeing once to herbicides revealed that bentazon and butralin gave a significant reduction in dry weight of grasses.Regarding total annual weeds, applying either clethodim or butralin was superior in their control, followed by fluazifop-butyl.The best yield of peanut was achieved using clethodim , followed by fluazifop-butyl and butralin.Whereas bentazon gave the lowest yield of peanut pods / fed .Seed oil content was not affected by the applied treatments in both seasons .The effect of hand hoeing x herbicides interaction was not significant on all studied characters in both seasons.
