In this study, possibilities of using wheatgrass juice, as an encouraging or activator of seedling growth on corn, were investigated. In order to obtain grass juice, wheat seeds (bread wheat) were sown in plastic boxes and were harvested on the 10th day. Wheatgrass juice was obtained by using an electronic juicer. Pots with 10-15 cm diameter were filled with perlite+peat mixture and three corn seeds were sown into each pot. Fresh wheatgrass juice was used to irrigate the corn seeds and tap water was used for control pots. Seedlings were removed and washed at the end of 30th day. Stem and root lengths and weights of the seedlings were determined. In order to determine the effect of wheatgrass juice on Rhizoctonia solani, the pathogen isolate was grown on Petri dishes with Potato Carrot Agar medium and transferred onto pots with perlite. Fifteen corn seeds were sown in each pot. Seeds were then irrigated with distilled water (control group: Rhizoctonia solani+distile water) or wheatgrass juice (Rhizoctonia solani+wheatgrass juice). Disease severity was determined two weeks after sowing. As a result of the study, wheatgrass juice was significantly reduced both lengths and weigths of the corn seedlings (root+stem). It was also found that wheatgrass juice increased the severity of disease symptoms caused by Rhizoctonia solani.
