Stimulation of Barley (Hordeum Vulgare L.) growth with local Trichoderma sp. isolates

Abstract

Trichoderma species are used as biological control agents against plant pathogenic fungi. In addition, some isolates of Trichoderma species produce metabolites that promote plant growth. In this study, it was aimed to determine the effect of local isolates of Trichoderma sp. and a commercial microbial fertilizer containing Trichoderma harzianum on the growth of barley. The experiment was carried out according to the randomized plots experimental design. Barley seeds were inoculated with spore solutions of local isolates and then compared with controls (without inoculation and commercial fertilizer). Plant height, root length, root dry weight, shoot dry weight and chlorophyll content were determined. The effects of isolates were different. In this study, plant height was increased with the application of local isolates. The difference between isolates was statistically significant. Isolates were determined to have positive effects on barley growth.
