|Fruiting||Pods ripen during December to February, remains on the trees for a long time.|
Occurs wild in the forests as well as avenues and gardens. It can grow on a variety of soils. It comes up well on laterites. Deep loamy soils with good moisture supply supports good growth while stiff clay, gravelly soils restrict the growth. Identified by greenish white flower heads and straw-coloured pods.
Morphology of the Fruit/Seed : Pods 15 to 30 by 2.5 to 5 cms in size; thin, flat, strap-shaped, round at both the ends; pale straw coloured, reticulately veined. Seeds 6 to 12, 8-12 mm by in size, ovate or oblong, compressed, pale brown, smooth with a hard testa.
Seed Collection and Storage : Pods are collected, dried, thrashed and winnowed to get clear seeds. The viability of the seeds remains well for at least one year. It should be stored in sealed tin with insecticide since the seeds suffer from borer attack.
Pretreatment : Soak the seeds for 24 hours in boiled water and allow to cool; or soak the seed in cold water for 48 hours; or immerse in H2SO4 for 5 minutes.
Nursery Technique : Pretreated seeds are either sown in primary beds in March to April in lines (15 cms apart) and in the lines 2 cms apart. After 5 cms of growth, the seedlings are pricked out to polybags. The seeds can also be directly put in the bags (2 per each).
