Corn Grown in Caves: The Future of Farming?
Caves and mines could be the future of farming.
Researchers from Purdue University found that lowering temperatures for two hours each day reduces the height of corn crops without affecting its seed yield, a technique that could be used to grow crops in a controlled environment.
Professor of Horticulture Cary Mitchell says isolated and enclosed environments can stop genetically modified pollen and seed from spreading.
Mitchell and other researchers installed a growth chamber with insulation and yellow and blue lamps in a former limestone mine in Marengo, Indiana, to grow the corn.
By dipping the temperature they were able to reduce the stalk height without affecting the number and weight of the seeds.
