Pre-germination treatments and application of soil amendments for supa (sindora supa merr.)/ Novelyn D. Buhang Bayombong: Nueva Vizcaya State University, 2023. xiii, 68 leaves : colored illustrations, photos ; 28 cm. This study aimed to determine the optimal pre-germination techniques and sod amendments for supa through two experiments. The first experiment tested four pre-treatment techniques, control, soaking in cold water for 12 and 24 hours, and soaking in hot water for 5 and 10 minutes. The second experiment applied different soil amendments to transplanted seedlings: garden soil/control, 2.1 garden soil and cow dung, 2:1 garden soil md chicken manure, 2:1 garden soil and vermicompost, and 2:1 garden soil and sawdust Both experiments were arranged in a Completely Randomized Design. Results showed that supa seeds soaked in hot water for 10 minutes (14) had the highest percentage germination and germinative energy, while seeds subjected to cold water for 24 hours (T2) had the earliest means days of emergence. There was no significant difference among treatments for percent germination and germinative energy. Regarding soil amendments, supa seedlings had a 100% survival rate is all treatments except for chicken manure (T2). The sawdust treatment resulted in the highest increase in root collar diameter, root length, and number of roots while vermicompost resulted in die highest increase in shoot length, chlorophyli consent, and root biomass. The untreated and cow dung treatments resulted in the highest shoot biomass. All parameters were significantly affected by the different amendments, except for the number of roots and root biomass.
