order to evalution of different weed control methods in Entezari and Spring planting date of rainfed chickpea , this experiment carried out in Marageh and Kermanshah research stations as RCBD with 26 combined treatments in 4 replications for four years. Dates of Entezar and spring planting were main plots and 13 weed control treatments were sub plots. Weed control levels included hand weeding (2 levels), mechanical weed control (2 levels), chemical weed control( 6 levels), mixedcontrol method(2levels) and local check ( no weed control). The results showed that there was significant different between treatments (P%5), and means comparison showed full weed control had highest yield (1029 kg/ha) but 2 time mechanical controlwith 468.5kg per ha give the lowest yield .Handy weed control treatments had more grain yield than mechanical and chemical control. In both research places, fall weed control together with combined control were the best treatment in biomass production. In marageh lentagran herbicide (2.5 L/ha) had lowest effect on weed biomass redaction in rainfed chickpea farms, bat hn sararoud station persuit(0.6 L/ha) in early autumn and desmedifam (2.5 and5 L/ ha) had the lowest yield. Key words: chickpea ¡ entezari planting ¡ spring planting, weed control. : Abstract
