Abstract
Selection of indian trumpet flower (Oroxylum indicum (L.) Kurz) cultivars for high-yield and beta-carotene content in the Lower Northern Region. Objective: To select indian trumpet flower cultivars with high yield and high beta-carotene content. Using a randomized complete block design of 4 replications, 3 plants per replication, 9 treatments, indian trumpet flower cultivars STI-1, STI-2, STI-3, STI-4, STI-5, STI-6, STI-7, UTT-1 and PCT-1. Conducted at Uttaradit Agricultural Research and Development Center from October 2022 to September 2024. Growth studies revealed that the STI-3 strain of indian trumpet flower had the lowest height in the first year, measuring 2.71 meters. And in the second year, the STI-7 variety of indian trumpet flower measured 3.86 meters. In the first year, the STI-2 variety of indian trumpet flower had the widest base circumference, measuring 28.44 centimeters. In the second year, the STI-3 variety of indian trumpet flower had the widest base circumference, measuring 47.08 centimeters. In terms of fresh pod weight, the STI-2 variety of indian trumpet flower showed the highest pod weight, measuring 428.8 grams per pod. There was no statistically significant STI-7 variety, which yielded a pod weight of 427.0 grams. However, there was a statistically significant difference compared to other strains. The STI-7 variety of indian trumpet flower yielded the highest yield per plant, at 15.0 kg. There was no statistically significant difference in yield per tree between STI-5 and UTT-1 indian trumpet flower varieties, with yields of 14.1 kilograms and 14.0 kilograms, there was a statistically significant difference in yield per tree with the STI-2 indian trumpet flower variety, which averaged 10.9 kilograms, and indian trumpet flower varieties STI-6, STI-4, PCT-1, STI-3, and STI-1 yielded average production per plant of 8.74, 8.09, 7.28, 6.65, and 5.06 kilograms, respectively. Beta-carotene content, indian trumpet flower varieties STI-3 was found to have the highest beta-carotene content at 983.66 µg/100g, followed by indian trumpet flower varieties STI-4, PCT-1, UTT-1, STI-6, STI-7, STI-5, STI-1, and STI-2, which had beta-carotene contents of 748.93, 710.61, 697.31, 618.91, 587.15, 549.69, 452.33 and 444.89 µg/100g, respectively.
