In order to evaluate the effect of neighboring plants on some shade avoidance mechanisms, an experiment was conducted in Ferdowsi University of mashhad in 2016. farm in spring of 2016. The experimental was designed as a factorial with 3 factors based on a randomized complete block design with 4 replications. The first factor consisted of the neighboring period of the plants with red bean (15, 30 and 45 days), the second factor included the number of plants adjacent to red beans (1, 2 and 3 plants) and the third factor included After completing the neighboring time for each treatment, all plants neighbored with target plant (central) were removed and the target plant remained to grow. This work was performed 15, 30 and 45 days after planting. In the third stage (45 days of neighboring), after removing the third groups of neighboring plants, all target plants were harvested and some morphological traits such as plant height. The results showed that among the factors, only the duration of neighboring was effective on dry weight changes of red bean. The maximum red bean biomass (21 g / plant) was obtained from 45 days of neighbor-free treatment, regardless of non-neighbor treatment. After biomass separation, it was found that the decrease in light quality had effect on shoot biomass consequent with shoot stretching for light. At the 45 days neighboring, the highest amount of shoot biomass was 5/2 gr, while light quality had no effect on leaf biomass
