Assessment of Drought Adaptation in Hevea Brasiliensis PB 260 Clone Seedlings During El Nino Events
Journal Title: Organic Farming - Year 2024, Vol 10, Issue 1
Abstract
The atmospheric El Nino phenomenon, characterized by elevated sea surface temperatures in the eastern Pacific Ocean, leads to reduced precipitation and increased temperatures in Indonesia due to diminished influx of moist air. These conditions necessitate the development of drought-resistant rubber (Hevea brasiliensis) seedlings, particularly for regions susceptible to such climatic variations. This study focuses on the PB 260 clone, investigating the efficacy of burnt husk applications in enhancing drought resilience. Employing a non-factorial randomized block design (RBD), three treatments were administered to the seedlings: no burnt husk, burnt husk as mulch, and burnt husk as a planting medium, with each treatment replicated three times and utilizing 30g of burnt husk per polybag. It was observed that the application of burnt husk as mulch significantly promoted root growth compared to the other treatments. This was quantified by measurements showing an increase in root length (98.7m), surface area (45.54m²), and volume (30 mL). These results suggest that the use of burnt husk as mulch might offer a viable strategy for enhancing drought adaptation in Hevea brasiliensis, providing a foundation for earlier tapping maturity through improved root development under drought conditions.
