Artificial Propagation

Artificial propagation is by seeds. Seeds can be stored in sacks up to 20 days. 1 kg will contain about 2500 seeds. Both direct sowing or by transferring nursery raised seedlings to fields are practiced. It is good to sow seeds soon after collection as they are recalcitrant. In the case of direct sowing, shady and weed free localities are preferable. Shade trees should be removed after 4-5 years of growth. Usually, a distance of 3 m x 3 m or 4 m x 4 m are used. If nursery raised seedlings are used for planting, shady areas have to be preferred. After sowing, soil covering of thickness not more than 4 mm is given. If there is no rainfall, regular watering is essential. Germination takes place within 2-3 weeks.
