The average and top yields in tonnes per hectare come from the trials each variety went through to be registered with the NSIC, and from what the seed companies say about their own seed.

What farmers harvest today can be different. Newer harvest records, the season, the place, the soil, the water and the care all move these numbers over time.

So use them to compare varieties, not as a promise for your field. Ask your seller or your agriculturist how the variety did on farms near you in the last few seasons.

Compare it with the others in our melon variety finder, or see every crop variety we list. For the crop itself, read our guide: Land preparation for gourds and melons.

How long does it take, and how much does it yield?

Tam Dew melon takes 90 to 120 days from sowing to harvest. A shorter crop frees the field sooner and dodges more of the weather, while a longer one often fills more.

Trial yields come from well managed plots, so your own will depend on water, fertilizer, pests and timing.
