Brief Description
Among the nursery techniques that needs to be established in the production of good quality planting stocks using wildlings includes the application of rooting hormone, appropriate potting media, nutrient requirement, watering and hardening of planting materials. To date, information on the production of planting stocks using wildling is still wanting. Thus, determining the appropriate cultural management for wildling could facilitate and ensure the continuous supply of quality planting materials and could possibly reduce the cost of nursery operation without sacrificing the quality planting material produced.
Seedlings that germinated and growing naturally under the identified superior mother trees (wildlings) in different locations will be collected for this study. Five dipterocarps including other timber producing indigenous species will be evaluated and set-up separately for each activity and these will be conducted in the MMSU Central Nursery from September 2012-December 2015. The different activities will be conducted in continuing process such that the promising result obtained from the preceding activity/ies will be integrated in the succeeding activities to achieve a more reliable data/information.
The activities will be laid-out using the appropriate statistical designs and tools and will be replicated three times.
Activity 1. Growth performance and survival of wildlings to types, rates and dipping time of rooting application
- conduct separate studies on the different rates of rooting hormone and dipping time
Activity 2. Growth performance and survival of wildlings to different potting media
- conduct separate study on the effect of different potting media of at least five indigenous timber species using wildlings
Activity 3. Survival and growth performance of wildlings to various types and rates of fertilizer and GA3 application
- conduct separate fertilizer studies to five indigenous timber species by wildlings
Activity 4. Quality and vigor of planting stocks to different hardening-off practices and watering frequency using wildlings as planting material
- conduct hardening off strategies and watering frequency to wildlings of five indigenous timber species
Expected Output
For this study, it is expected to establish a propagation protocol for wildlings.
Acty 1. Effective rate and dipping time of rooting hormone
Acty 2. Ideal potting media for containerized wildlings
Acty 3. Appropriate nutrient requirement for containerized wildlings
Acty 4. Ideal hardening practice for the individual species
