Abstract

Winged bean is a tropical vegetable crop that has the potential to be developed as legumes. Quality of young pod of winged bean can be determined by the age of harvest. This study aims to determine the production and quality of two varieties of winged bean pods with different harvest ages. The experiment was carried out from September 2020 to February 2021 at IPB experimental station, Darmaga, Bogor. The experiment used a factorial completely randomized block design with three replications, namely two winged bean varieties (Fairuz IPB and Sandi IPB) and harvest age (8, 10, 12, and 14 days after anthesis (DAA)). The results showed that the two varieties had different production and quality of young pods. Fairuz had higher number of flowers, the number of pods, total weight, and productivity of young pods compared to those of sandi. Sandi had high scores on pod length, pod softness, and anthocyanin content. The delay in harvesting caused the weight of young pods and productivity of young pods at the age of 14 DAA to be higher. Young pods harvested at 8 DAA were the softest and had the lowest thickness, and can be recommended to harvest the young pod.
