During 2009 and 2010 seasons, three bio-stimulants namely EM (Effective Microorganisms), yeast and humic acid were used as a trial for replacing inorganic N partially in Anna apple orchard. Combined application of inorganic N beside any bio-stimulants was favorable than using inorganic N alone in improving growth, nutritional status of the trees as well as yield and fruit quality. The best biostimulant was EM. Humic acid ranked the second position in this concern. For reducing pollution due to nitrate and nitrite in the fruits and for improving production of Anna apple, it is advised to use N as inorganic N at 60 % of the suitable N dose along with application of EM or humic acid each at 30 ml/tree/year.
