Weed control is very important in preventing crop loss. In this regard, the utilization of the effects of plants can play an important role in controlling and destroying weeds. In order to investigate the effects of the aqueous extract of pine leaf on germination stage and some morphological traits of (Phaseolous vulgaris cv,white bean) (Phaseolous vulgaris cv, chiti bean) and weeds (Panicum miliaceum L.) (Amaranthus retroflexus L.) a completely randomized design with three replications was conducted at Ferdowsi University of Mashhad Experimental treatments were selected at four concentration levels of 25, 50, 75 and 100% w / v of the aqueous extract of pine leaf, and the inhibitory effects of the above treatments were studied on crops of (Phaseolous vulgaris cv,white bean) (Phaseolous vulgaris cv, chiti bean) and weeds (Panicum miliaceum L.) (Amaranthus retroflexus L.). The inhibitory effect of crops on white bean has been found on chiti beans and Panicum of Amaranthus. But the effect of alteration on the Panicum and Amaranth plant was statistically significant

Allelopathy, Pine (Pinus eldarica L.), White beans (Phaseolus vulgaris L. CV, (White bean)), Chiti beans (Phaseolus vulgaris L. CV, (Chiti bean) ), wild Panicum (Panicum miliaceum L.), wild Amaranthus (Amaranthus retroflexus L.)
