Seed Rate
For seed rate of 100-120gm per acre.
Seed Treatment
For good germination, treat seeds with Thiourea@100-200ppm and Gibberellic acid@200ppm. Before seed sowing, treat the seeds with Thiram@3gm/kg of seed to protect the plant from soil borne diseases.
Sow seeds in polythene bags of 25x10cm having thickness of 150gauge. Make hole of 1mm diameter on lower part of polythene bag for proper drainage of water. Then fill polythene bags with equal proportions of FYM, soil and sand. Before sowing do seed treatment. For transplantation, six-seven week old seedlings are used.
Time of sowing
In spring season, planting is done in February-March whereas June-July are ideal months for planting in monsoon season and in autumn season, planting is done in October-November month.
Spacing
Generally spacing of 1.8mx1.8m is used. In case of high density planting, spacing of 1.5mx1.5m gives good return.
Â
Sowing Depth
In nursery sow seeds at depth of 1cm.
Method of sowing
Direct sowing of seeds or transplanting of seedlings in main field.

Fertilizer Requirement (gm/tree/year)
| UREA | PHOSPHORUS | POTASH |
| 150 | 80 | 100 |
Organic Fertilizer Requirement (gm/tree/year)
| BIO-DAP | NPK | MIX FERTILIZER |
| 150 | 80 | 100 |
Apply fertilizer dose of Urea@150gm, Phosphorus@80gm, Potash@100gm per tree per year. Apply fertilizers in four splits i.e. 1st, 3rd, 5th and 7th months after planting.
Weed control is necessary during young stage of plant. Depending upon weed intensity, do frequent and light weeding operation. Apply Fluchloralin or Butachlor@ 800ml/acre. Mulching is also effective way of controlling weeds. Apply plastic film or straw of rice or sugarcane as mulch few days after transplanting of seedlings.
Removal of male plant: After flowering remove male plants maintaining one male plant for every 10plants.
Irrigation is depend upon soil type, climatic conditions etc. Apply irrigation at interval of 15days in winter and in summer apply at interval of seven days. Avoid contact of water with stem. Also avoid water logging condition in field.
PLANT PROTECTION  
Stem rot:Â
Stem rot:Â Water like wet spots are seen on plant stem. The symptoms get spread on all sides of the plant. Plant leaves fall apart before it is fully developed.
Treatment:Â To control this disease spray with M-45@300gm in 150ltr water.
Root rot or wilt:Â
Root rot or wilt:Â The disease causes rotting of roots which ultimately result in plant wilting.
Treatment: To control this disease drenching with Saaf@400gm in 150ltr water.
Powdery Mildew:
Powdery mildew:Â Patchy, white powdery growth appears on upper surface of leaves also on main stem of infected plant. It parasitizes the plant using it as a food source. In severe infestation it causes defoliation and premature fruit ripening.
Treatment:Â Spraying of Thiophanate methyl 70% WP@300gm in 150-160ltr water/acre is done.
Papaya mosaic:
Papaya mosaic: The symptoms appear on top young leaves of the plants.
Treatment:Â To control this pest spraying with Malathion@300ml in 150ltr water is done.
