Enhanced growth of cabbage and red beet by Trichoderma viride

摘要

The main agricultural importance of Trichoderma species was not so far away mainly suppression of plant diseases. Novel investigations emphasize their potential to stimulate plant growth independently of suppression of any plant disease. However, Trichoderma spp. and even biotypes of same species vary between each other in its effectiveness both in the control of plant pathogenic fungi and in the promotion of plant growth and increasing yield. The subject of this study was to evaluate growth promoting effect of two indigenous T. viride stains STP16 and STP8 on cabbage and red beet. Increment of fresh and dry weight accomplished by STP16 was statistically significant so, it could be concluded that growth enhancement of 27% at red beet and 29% at cabbage is significant.
