Fruits of Apricot (Prunus armeniaca L.) varity Canino mature trees growing in loamy clay soil at the experimental orchard of the Horticulture Research Station at El Kanater El Khayreia, Kalubia Governorate, Egypt, were sprayed once at full bloom during seasons 2013 & 2014 with yeast extract at 10, 20 and 30 g/L, humic acid as Actosol® (contains 2.9 % humic acid) at 40, 60 and 80 ml/L and yeast extract at 20 g/L + humic acid at 60 ml/L, besides water spray as control. Mature fruits were harvested and stored at 0°C for six weeks. Results indicated that foliar application of 20 g/L yeast extract plus 60 ml/L humic acid/ tree gave the best effect on tree yield and increased vegetative growth parameters, total leaf chlorophyll content and leaf mineral content (N, P, K and Mg). Also, this treatment was effective in improving fruit quality and storability of apricot fruits under cold storage conditions comparing with other treatments. © 2015, Sphinx Knowledge House.
