It can yield 20-30 tons per acre and would be the top forage crop if it were not for the fact that to truly thrive, it likes a moist, rich soil with a hot growing season. I am growing for an awesome compost maker! Teosinte will need at least 5-6 months of good weather to produce a crop and does great in the South and Southwest. Unlike corn, it is not affected by serious pests or diseases.
