In order to evaluate the effect of some bio-stimulators on yield and fruit quality of apricot cv. ‘Shekar pareh’ management functions were studied in the spring of 2014 in Abarkouh of Yazd province. The experiment was based on randomized complete blocks design with seven nutritional treatments included control (water spraying), humic acid one and two per thousand, aminol forte three and six per thousand and humi forte 0.5 and 1 per thousand in four replications. Bio stimulators were applied just spray twice during the growth period including two weeks after full bloom and a month after it. Results showed that the bio-stimulators effects significantly affected the measured traits except for the titratable acidity (based on malic acid), firmness and maturity index. Humic acid treatment reduced physical properties, total soluble solids and vitamin C. Aminol Forte with three per thousand concentrations increased most of the physical and chemical characteristics, but three per thousand to six per thousand concentrations had the effect of decreasing. Humi forte also increases fruit's carotenoid and vitamin C. Therefore, it seems that between treatments, aminol forte bio-stimulator enhanced yield and improve the quality of apricot fruit. Therefore, it can be recommended to spraing of aminol forte with three per thousand concentrations at the suitable time.
