Following collection, pods are dried in the sun for 5-7 days. Pods are then lightly pounded with a hammer to extract seeds. Extracted seeds are dried again in the sun for 3-4 days and then stored in bags under well ventilated, dry conditions. There are approximately 21,000 seeds per kg. Removed from the water, moist seed is stored overnight and sown the following morning.
Seedlings emerge within a week.
Nursery production should be initiated in November or December, 4-5 months before the planting season. Well drained sandy loam soil from beneath A. odoratissima trees is recommended for nursery use. The use of large nursery bags is recommended to encourage growth of a deep taproot. Every two weeks seedlings should be fertilized with a well decomposed liquid compost or a standard phosphorus and potassium fertilizer. In large nurseries, 4-10 cm seedlings are sprayed every two weeks for protection from insects and fungal diseases.
