What a disappointment! There could be a couple of reasons:
• the flower/s were not adequately pollinated or pollination failed; if your garden area lacks flowers that attract pollinators, hand pollinating (rubbing male/female flowers together)
• cool and/or cloudy weather; these need heat: try black plastic under to hold heat
• lack of moisture; these need lots of water
• too much nitrogen in your soil; use a fertilizer higher in phosphorus and potassium than in nitrogen
