Production Technology of Papaya

Soil and Climate

  • Well drained loam to sandy-loam soil rich in organic matter
  • Papaya thrives well on soil with pH ranging from 5.5 to 7.0
  • Plants are highly sensitive to flooding
  • It has been ranked as not tolerant or extremely sensitive to salt stress
  • The optimum temperature for papaya is 210 to 33C
  • Papaya is classified as a shade avoiding species

Land Preparation

  • Land should be prepared well
  • For quick drainage bed system must be followed
  • Bed should be 1.7 m wide and 20-25 cm high
  • There should be 30 cm drain in between two beds
  • The length of bed will be as per land
  • Bed should be raised before pit preparation

Raising of seedling

  • Seeds should be sown in 10 cm apart rows in seed beds at 3-4 cm distance and 1.0-1.5 cm depth
  • Seeds are also sown in perforated poly bags (15 ´ 10 cm) filled with 50% river silt and 50% cow-dung
  • 2-3 seeds are advised to sow in each poly bag
  • Seeds should be soaked in water for several hours before sowing
  • Watering should be done at 2-3 days interval after seed sowing

Number of seedling required

  • Pits are prepared at 2 m apart in the beds (2 × 2 m spacing) and three seedlings are transplanted in each pit. So, a total of 7500 seedlings are required for 2500 pits per hectare

Pit preparation

  • Pit size should be 60 ´ 60 ´ 45 cm
  • Manure and fertilizers like cow-dung 15 kg, TSP 500g, gypsum 250g, boric acid 20 g, zinc sulphate 20 g are to be applied per pit 10-15 days before transplanting

Time of seed sowing and transplanting

  • September-October and December-January are two suitable time for seed sowing
  • Seedlings become ready for transplanting at 40-50 days after sowing


  • Three seedlings are to be planted per pit at 30 cm distance in triangular form
  • In case of monoecious type one seedling is planted per pit
  • Poly bag is to be removed carefully keeping ball undisturbed
  • Seedlings are to be placed in the same depth as it was in the bed or in the poly bag

Top dressing of fertilizers

  • 450-500 g each of urea and MP are to be applied per pit
  • 50 g urea and 50 g MP are to be top dressed at one month interval starting from one month after planting
  • The doses should be doubled after flowering
  • Irrigation is essential following top dressing in dry season


  • Papaya field should always be kept weed – free
  • In the rainy season weeding should be done by ‘Hasua’ or lawn mower without loosening the soil

Irrigation and drainage

  • Frequent light irrigation is required during dry season
  • During rainy season quick drainage must be ensured

Removal of extra plants

  • After fruit set two plants from each pit are to be removed keeping the best female plant
  • 5% male should be allowed to facilitate pollination

Fruit thinning

  • Most of the papaya varieties bear 2-3 fruits per cluster
  • Extra fruits should be thinned out keeping the best one only
  • In 2nd or following years, the plant bears overcrowded fruit. The smaller fruits needs to be pruned

Diseases, insect pests and remedy

Damping off and collar rot

  • Serious disease of papaya in the seed bed and causes considerable damage to the crop during rainy season.
  • Damp growing condition favors the disease.

Step by Step Production Technology of Papaya Fruit


  • Seed treatment with Vitavax or Captan @ 2-3 g per kg of seed
  • Sterilization of nursery bed by burning saw dust or rice hull (6 cm thick)
  • Soil amendment by poultry litre @ 5 t/ha
  • Solarization of the bed prior to seed sowing
  • Drenching of Ridomoil MZ @ 2 g/L


  • Brown lesions are appeared on fruits which enlarges with the development of fruit

Step by Step Production Technology of Papaya Fruit


  • Spraying of Knowin or Topsin @ 2 g/L 2-3 times at 10-15 days interval

Papaya mosaic virus

  • Yellow patches are appeared on leaves and fruits, bending of petiole and plant growth become stunted
  • The disease is transmitted by aphid

Step by Step Production Technology of Papaya Fruit

Ring spot virus

  • The affected plants are in growth, show yellow mottling and distortion of leaves, bending down of petiole followed by death of the plant
  • Oil soaked ring spots are found on stem and fruits. Diseased plants yield little or no crop
  • The disease is transmitted by aphids

Control measure

  • Uprooting and burning of diseased plant
  • Control of vector

Mealy bug

  • Mealy bugs suck on leaves, fruits and weaken the plants. Plant growth and yield are affected seriously
  • They also cause sooty mould secreting honey dew


  • Clean cultivation, destruction of infested leaves and fruits with insects
  • Application of Dimethoate 40EC (Perfecthion/ Taphgar) @ 2 ml/L 2-3 times at 15 days interval


  • Nematodes cause root-knot in papaya. The affected plants become weak and dwarf
  • They also facilitate entrance of soil borne pathogen
  • Infected roots, rain and irrigation water help dissemination of nematode


  • Crop rotation with mustard, ground nut, wheat or maize
  • Application of Furadan 3G @ 5g per pit
  • Soil amendment with poultry liter @ 3 t/ha or MOC @ 300 kg/ha

Nutrient deficiency problem

B deficiency

  • Papaya is highly sensitive to B
  • B deficiency creates three symptoms i) curling of leaves, ii) secretion of latex from developing fruits and iii) deformation of fruits

Step by Step Production Technology of Papaya Fruit


  • Application of boric acid @ 20 g/pit
  • Spraying of boric acid @ 2 g/L 2-3 times at 10-15 days interval when symptoms are appeared on plants or fruits

Zn deficiency

  • The plants turn mixed colour of white-green. Leaf venation show white net like appearance.


  • Spraying of ZnO to leaves @ 2g/L 2-3 times at 10-15 days interval

S deficiency

  • Leaves turn yellow, the plants become weak and show stunted growth. The symptom resembles mosaic virus disease


  • Spraying of Thiovit or Cumulas @ 2 g/L 2-3 times at 10-15 days interval


  • When the latex of the fruit becomes almost watery, the fruits is considered ready for harvest
  • Fruits for local market can be harvested when they are half ripe
  • Yellow bands are appeared on fruit surface
  • The first crop of fruits is harvested in 12-14 months after transplanting
  • Fruit should be harvested in the morning
  • Fruits can be dipped in hot water at 55C for 5 minutes
