Hi Ngoni,
I don't have the answer to your question, but found this site on growing gourds where they sell the seed for giant bushel gourds. You will only find basic info there.

Here's a conversation about them that you might find helpful.

You can also do a search at the bottom of the page. I searched with the word bushel and found 33 posts.

If you don't find the info you need, you might want to ask these folks.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
