Background and Objective: The frequency of different irrigation on melon has an impact on the success of pollination and fruit yield characteristics. The objective of this study was to determine differences in successful pollination and yield characteristics in two populations with different irrigation frequencies. Materials and Methods: This research was conducted by performing artificial crosses on several melon varieties. The utilized materials involved melon seeds of Melindo, Madesta and Glamour varieties. This research was carried out at the greenhouse of Brawijaya University, Malang, Indonesia. The observation was made on successful pollination and on several yield characteristics (fruit weight, fruit diameter, fruit length, flesh thickness and fruit sweetness). Results: The highest percentages of successful pollination occurred with proportions of 1♀:1♂, 2♀:1♂ and 3♀:1♂ with irrigation every 2 days at 06:00-11:00 am and with proportion 1♀:1♂ with irrigation every 6 days at 06:00-09:00 am. For the mean yield characteristics of melons, the largest fruit weight, fruit diameter, fruit length and flesh thickness are for the ME (Melindo)×MD (Madesta) hybrid cross. The highest average sweetness level is for the ME×ME hybrid cross. Conclusion: The percentage of successful pollination and melon fruit quality in normal conditions are better than under drought stress.
