الملخص

This research was carried out in Ain Aljrn, Al-ghab, Hama, and Province during the two agricultural seasons 2016 and 2017. The experiment was conducted in an open field.

This research included variety of hybrid muskmelon (Cucumis melo L.)

And the largest number of feminine blossoms, 22.36 on the plant, and number of fruit, (4.05) fruit/plant, and gave high productivity (8.69) TN/Dunm.   The results indicate a strong positive correlation between vegetative and characteristics of fruit growth, and the correlation between leaf surface area and productivity is strongly positive (r = 0.92).
