Pipián is originally from the tropical Americas. The fruit is harvested and used when immature. The mature, larger fruit is used for seed, both for propagation and for consumption. The seed is open-pollinated, and thus there is tremendous variation in the phenotypes.
In 1998, the government of El Salvador estimated that there were about 1,000 acres gown in El Salvador.
In El Salvador, it is recommended to plant approximately 2,000 plants/acre. Approximately 2-3 pounds of seed is needed per acre. Harvest begins about 35 days after seeding and can continue until frost.
As a member of the curcurbit family, fertility and pest management strategies will be the same as for pumpkin and squash varieties grown in the Northeast.
Currently there are no commercially-available seed for pipián. Trials are planned at the University of Massachusetts research station in 2006.
