CULTURAL MANAGEMENT


Propagation
Papaya is propagated with seeds. Wash the seeds and remove the gelatinous covering as this can inhibit germination. Get seed from selected fruits produced by controlled pollination to insure the quality and uniformity of the plantings. Raise 3-4 seedlings per container (plastic bag) and field plant when they are 20 cm high.

Land preparation

For open field planting, the land is plowed and harrowed twice. An elevated plot along the row is made by plowing on barring with two passes on each side. This will insure proper irrigation and drainage
Organic fertilizer and manure should be spread and incorporated in the soil during land preparation. .

Planting

Planting distance is 2,5 m x 1.6 m to 3m x 2 m. This can be increased if papaya is inter-cropped with coconut and other crops. Retain one female or one hermaphrodite plant per hill by thinning out extra plants at flowering stage. In the absence of hermaphrodite plants, one male plant per 25-100 female plants is retained as pollinator.
There are no reliable characteristics to distinguish male, female and hermaphrodite plants until they bear flowers. This is the reason why 2-3 plants are recommended to be planted and allowed to grow on each hill until flowering. The plants bear flower in 6 months after germination.
When the flowers appear and the sex determined, remove the male and undesirable plants. Leave only on vigorous hermaphrodite of female plant.

1. Remove side growths along the leaf axles that occur during the early stages of plant growth. They compete with plant nutrients needed by the plant. These areas can also harbor pests and diseases

2. Always exercise general sanitation. Clean fields minimize spread of pests and diseases.

3. Regularly remove diseased, senescent and dried leaves. These areas provide good habitat and unnecessary source of pests and diseases.

4. Cut down and carry away blown down and diseased trees from the field. Diseased leaves and fruits will be removed and buried or burned.
