MORFOLOGI DAN PERTUMBUHAN TANAMAN CHAYA (Cnidoscolus aconitifolius (MIll.) I.M. Johnst) DENGAN DURASI KEKERINGAN YANG BERBEDA

Chaya (Cnidoscolus aconitifolius) is an annual vegetable species known for its tolerance to drought stress. However, in the cultivation process, prolonged drought stress can affect the growth, morphology, biomass, and quality of chaya plants. Drought is a condition where soil moisture content is very low. One effort that can be made to observe the response of chaya plants to drought is by applying different durations of drought. This study aims to determine the morphological growth of chaya plants and assess the tolerance level of chaya plants to drought stress. This study was conducted at the Greenhouse of the Faculty of Agriculture, Sriwijaya University, from June to September 2025. This study used a randomized block design (RBD) consisting of 5 drought treatments, namely: control (C1), 4 days of drought (C2), 8 days of drought (C3), 12 days of drought (C4), and 16 days of drought (C5). The planting medium composition used was topsoil: goat manure with a ratio of 3:1. From this method, 5 treatments were obtained, and each treatment had 4 plants, resulting in 20 combinations, which were then repeated 3 times, resulting in 60 plants. This study used polybags measuring 35 cm x 40 cm. The results showed that chaya plants were able to survive up to 16 days of drought, but there was a significant decrease in growth and biomass as the duration of drought increased. Treatments C1 and C2 yielded the highest results for most growth and morphological parameters. Moderate to severe drought caused a decrease in leaf area, root diameter, and biomass, although there was an increase in root length as an adaptive response. Thus, chaya plants are classified as drought tolerant, but optimal growth is obtained under conditions of sufficient water availability to mild drought.
