Raising the Stimufol fertilizer level or IAA concentration applied as a foliar spraying on squash plants seemed to increase number and weight of fruits for early and total yields. Increased stimufol concentration decreased number of male flowers, consequently caused a depression in sex expression. Moreover, early total yield percentage was decreased with increasing stimufol concentration. Spraying squash plants with stimufol fertilizer at 8.0 g./L. with IAA at 50 ppm concentration, generally, showed a favourable effect on the early yield. In addition, squash plant needed to increase the number of stimufol applications to two sprayings or increase their concentration to 8 g./L.
