Sweetpotato Stem Cuttings Database in Preparation for Flight

Abstract

Since 1985, Tuskegee University has been engaged in research that addresses NASA's mission to achieve long-duration human space exploration on the moon and Mars. The successful research of Dr. George Washington Carver, the beginning of our long history of working with crops for food and industrial uses, is well known. This history and contemporary technical expertise in food/industrial crops, and our interest in pursuing new, interdisciplinary approaches to education and research led us to submit a proposal to NASA in 1985 to pursue the hydroponic production of sweetpotato for food for astronaut-explorers on future long-term, distant space missions. As a carbohydrate and dual vegetable (edible leaves), the versatile sweetpotato has the potential to be a key crop as a main source of energy and other nutrients such as beta-carotene, calcium and potassium. Sweetpotato is a crop very suited to space, as was documented in a monograph published by our scientists in 1984
