effect of foliar application of single solution of N, Zn and B and their
combination 7 days before full bloom on fruit set, and fruit quality parameters in olive zard cv. Were examined. The results of this study indicate that the urea spray increased
the initial fruit set while spraying the mixed solution of B and Zn caused significant
increase of precentage of final number during the harvest. The application of Band Zn
combination solution decreased the level of fruit abscission. Foliar nutrition application
with boric acid decreased the number of shotberries, but had no effect on olive oil.
