In order to study the effects of Dekap (0, 1, 2 and 3 L ha-1) foliar applications on some physiological and morphological treats of Cucurbita pepo an experiment was conducted based on Randomized Complete Block Design at Azerbaijan Shahid Madani University Research Farm. The result showed that the foliar application had significant effects on plant length, number of auxiliary branches, leaf number, number of female flower, total number of fruit, fruit diameter, fruit fresh weight, intact fruit number, fruit yield, number of intact and immature seeds in fruits and oil percent. The highest number of auxiliary branches, plant height, leaf number per plant and the highest data for oil percent, seed length, fruit fresh weight and fruit diameter were recorded at 1 and 2 L ha-1 foliar application. The highest data for intact seed number was recorded at 1 L ha-1 foliar application but, the highest number of immature seeds were recorded at 2 and 3 L ha-1 foliar application. The highest data for female flower number and total number of fruits per plant were recorded at 1 L ha-1 treatment. The treatment used in this experiment had not significant effects on protein content, seed dry weight, leaf dry weight, potassium and phosphor concentrations. Considering the fact that, in the present experiment there was no significant difference between 1 and 2 L ha-1 of Dekap foliar applications in some of the evaluated traits, so, we can claim that 1 L ha-1 Dekap foliar application can be recommended for the extension section.
