Papaya is a tropical, plant, very sensitive to frost. Optimum temperature is 25 - 30° C and minimum 16° C. The suitable ph value is between 6 and 6.5. The well-drained or sandy loam soil with adequate organic matter is most important for the papaya cultivation. In high rainfall area, if drainage is poor and roots are continuously drenched for 24 to 48 hours, it may cause the death of the plants. Sticky and calcareous soils are not good as rain water may accumulate in the soil even only for a few hours. In this case, higher raised bed and drainage ditch are recommended. The growing field should be irrigable and kept at suitable soil moisture which is necessary for the growth of papaya plants, although dry climate at the time of ripening is good for the fruit quality. Continuous cropping in the same field may result to poor growth and cause disease problem of papaya trees. Papaya does not like strong, cool, hot, dry or salty wind. It is better to grow in sheltered but full sunshine place. Staking and/or windbreak can decrease the damage to plants under strong wind.

RAISING SEEDLINGS

Seed Source:The seed must be from dependable source and sown as soon as possible. The remaining seeds must be sealed tightly and kept at cool (5 -10° C) and dry (under relative humidity 40%) place.

Seed requirement:One gram contains about 50 - 80 seeds, mostly 65 -75 seeds. It needs 50 to 80 g seeds per hectare at one plant per hill average of 80 % seed germination and 80% successful seedlings.

Growing season:The time of sowing depends upon the choice of fruiting season and danger of rain or frost.

Seed germination:The optimum temperature is 21 - 27° C, and of radical emergence is 19 - 29 °C. it take 1 - 4 weeks from sowing to emerge depending on the temperature. The seed may be treated with Thiram (TMTD) W.P. before sowing to control the fungus diseases at young stage.

Sowing method:It may be sown directly, but normally, it is better to be seeded to raise seedlings and transplanted.
