Goals & Objectives
The project aims to test a modified technique of restoring the degraded lands using Dalbergia cochinchinensis, which involves a combination of the cluster planting and Miyawaki method, and the use of coconut husks as a water-retaining agent, overall to find out an effective alternate planting method in rehabilitating degraded lands. The objectives of the project are to:
- Evaluate the cost effectiveness of cluster planting combined with the Miyawaki method in rehabilitating degraded lands;
- Determine the survival rate of test species (Dalbergia cochinchinensis) planted together with other species in a cluster using the Miyawaki method; and
- Demonstrate the beneficial effectiveness of local materials (coconut husks) as a water retaining agent on the survival of seedlings.
- Preparation and Establishment of Site Layout
- Production and purchase of seedlings.
- Layout and establishment of experimental plots
- Sampling of weeds
- Maintenance and Monitoring of Research Plots
- Maintenance weeding of experimental plots.
- Recording of the costs of establishing each plot including the cost of seedlings with photographs taken for documentation.
- Monitoring and measurements of survival and growth data of the climax, fruit trees, and pioneer species collected from established plots.
- Analysis of Data
- Measurement of the frequency of weeding cost of site preparation and planting and maintenance of three plots where they will be calculated and compared.
- A comparative analysis on the survival and growth rate of each species and each treatment will be done through using Analysis of Variance.
- Recording of the growth of weeds and the frequency of weeding will also be conducted.
- A statistical analysis comparing the growth of the plants in Treatments 1, 2, and 3.
- A comparative cost-efficiency of the three treatments.
- Policy recommendations on the potential of the Miyawaki method.
