Pick and Eat Crop Testing: Dwarf Tomato and Pepper as Candidate Space Crops

Dwarf tomato and pepper plants were grown in controlled environment chambers to assess their potential as space crops for supplementing the crew's diet. Six cultivars of each species were compared in initial tests and then down-selected to three cultivars of each. Initial selection criteria included fruit yield, growth height, and nutritional value. Following completion of a second production test with the three best performing cultivars, sample fruits of both tomato and peppers were then assessed for acceptance using tasting panels. Based on the criteria considered in these studies, Red Robin tomato and Pompeii pepper were recommended for consideration for use in space.
