Today, due to herbicides serious problem, most of people want to use replacement methods to control of weed. In order to study the effect of plastic mulch and paper on control of weed biomass and yield components in pepper, this experiment that was conducted as completely randomized block design with four replication and four treatments in filed condition, at agriculture faculty, Tabriz University in 2012. The treatments included four levels of mulch: white plastic, black plastic, paper and control (without mulch). Lambs squarters (Chenopodium album L.), redroot amaranth (Amaranthus retroflexus L.), Green foxtail (Setaria viridis (L.) P. Beauv), and bindweed (Convolvulus arvansis L.) were dominant weeds of this field. The highest yield of pepper was observed in black mulch. The results showed that application of different mulches cause significant difference between in fruit length, fruit weight, fruit number. The most of characteristics of pepper were highest in black and white mulch, respectively and as matter of fact the black mulch is the best mulch to control of weeds. Also, weed biomass was reduced in paper mulch compare with control.
