Abstract

This study systematically evaluated various container types and potting media formulations to optimize the production of high-quality sandalwood (Santalum album) planting stock. There is a high demand for quality planting material particularly by private farm lands and also for the specific purposes like timber production where the use of bigger sandal saplings is very much preferred for out planting. In the context of container raised seedling production, potting media is one of the important inputs and is primarily responsible for the healthy seedling production. To stay competitive and to satisfy the environmental concerns of using traditional growing media components such as river sand, potential alternatives were investigated in the present study. Results indicate that a 30 cm × 20 cm poly bag, when combined with a potting media mixture composed of soil, rice husk, and FYM in a 2:1:1 ratio, consistently yielded superior seedling growth. The assessed growth attributes, including collar diameter, shoot length, root length, total height, and dry weight, were significantly enhanced with this specific combination. The benefit-cost ratios (B-C ratios) for production in various containers varied, container C3 demonstrates a B-C ratio of 1.60, indicating a ` 1.60 return for each ` 1 invested. Container C4 shows the highest B-C ratio at 1.61, implying a return of ` 1.61 for every ` 1 spent. Root trainers (C3 and C4) offer economic advantages with well-developed roots and growth uniformity, making them favourable for seedling production. The highest benefit-cost ratio (B-C ratio) of 1.59 is associated with potting media P2, indicating efficient resource use and potential high returns.

Conclusion

These findings are not only vital for meeting market demands but are also critical in ensuring the long-term success of sandalwood plantations and the preservation of this iconic species. In conclusion, the findings presented in this study offer valuable insights into the selection of potting media for the production of Santalum album seedlings in nurseries. The benefit-cost ratios (B-C ratios) assessed the cost-effectiveness and potential returns of various potting media, with potting media P2 emerging as the most efficient choice, boasting a high B-C ratio of 1.59. This underscores the economic viability of using this specific potting medium and container. This approach not only proves cost-effective but also offers an environmentally friendly solution by repurposing abundant and sustainable resources, such as rice husk, which is readily available in rice-producing regions. Utilizing local organic waste materials in nursery operations not only reduces costs but also mitigates environmental concerns related to waste disposal and raw material scarcity. The study's findings have the potential to inform decision-makers and practitioners in the field, contributing to more sustainable and economically viable sandalwood seedling production practices in humid tropical regions.
