To study the response of pinto-bean yield and yield components in intercropping with maize and naked-pumpkin under weed competition, two similar experiments were conducted in Rasht and Roudsar separately each in a randomized complete block design with 3 replications on factorial arrangements experiment in 2013. The treatments of first factor consisted of  pinto bean (100 and 75%) sole cropping, maize – pinto bean (100-100 and 75-75%) double cropping and maize- pinto bean- naked pumpkin triple cropping (100-100-75 and 75-75-75%). The treatments of second factor include twice hand weeding and no weeding. The results showed that nine weed species were found in Rasht and six weed species were in Roudsar experimental stations. The broadleaf pigweed in Rousdsar and grassy weeds of Bermudagrass and hairy crabgrass were dominant in Rasht. In Roudsar area, the hand weeding treatments had outstanding role in weeds control, while, in Rasht experiments was not clear, due to presence of perennial weed. Double and triple cropping systems suppressed weeds more than sole cropping systems. In Roudsar, the highest number of pods per plant, number of grain per pod, 100 grain weight and grain yield of pinto bean were observed in sole cropping in hand weeding and the lowest amount of them were observed in sole cropping system in no weeding. In Rasht, the highest grain yield was observed in sole cropping with high planting density. Finally, double and triple cropping systems due to better weed control produced the highest yield and yield components in comparison with sole cropping systems in no weeding treatment.
