Yield, yield components, antioxidant activity and genetic variation of fifty genotypes on Vigna spp. were evaluated under two production systems (inorganic and organic agricultural systems) at the field trails in the Kingdom of Thailand. The experimental design was a Randomized Complete Block Design with four replications and twenty plants in blocks. It was found that pod length, fresh pod weight, number of seeds, number of pods, fresh pod yield, 100 seed weight and harvest index showed significant difference (p≤0.05). The highest quality number of pods was found on Fakdang 71.75 and 55.25 pod.plant-1 under inorganic and organic agricultural system, respectively. The Kangkragan produced the highest quality yield 1,385.20 and 1,135.30 g.plant-1 under inorganic agricultural system and organic agricultural system, respectively. Suarpran had the lowest quality yield 208.10 g.plant-1 under organic agricultural system. The highest values for trolox equivalent antioxidant capacity (TEAC) and 2,2-diphenyl-1-picrylhydrazyl radical scavenging ability (DPPH) were obtained from Panomsarakram and Fakdang (95.36 and 35.61% of inhibition, respectively). The outcome of this study can be used as guidance for Vigna spp. production in Thailand.
