During 2010 and 2011 seasons, Kelsey plum trees received yeast at different methods (via soil, via foliage and via soil and foliage) and doses (2.5, 5.0, 7.5 g/ tree/ one addition). Yeast was added at three times/ year. The effect of yeast treatments on yield and fruit quality was investigated. Application of yeast at different methods and doses was preferable in enhancing yield quantitively and qualititively rather than non-application. Application of yeast via soil surpassed the application

Negligible stimulation was detected among the higher two doses of yeast. Combined application of yeast via soil and foliage surpassed the application via soil or via foliage alone. Treating Kelsey plum trees three times with yeast via soil at 2.5 g/ tree (7.5 g. yeast/ tree/ year) + via foliage at 0.25 % gave the best results with regard to yield and fruit quality.
