Co 1, Co 2, Co 3, Co 4, Co 5, Co 6, Co 7, Coorg Honey dew and Surya. Co 3, Co 7 and Surya are gynodioecious (bisexual + female) types highly suitable for table purpose and Co 2, Co 5 and Co 6 are dual-purpose varieties for table and papain production.

1) Soil and climate
It is a tropical fruit and grows well in regions where summer temperature ranges from 35°C - 38°C. Tolerates frost and comes up to an elevation of 1200 m above mean sea level. Well drained soils of uniform texture are highly preferable to avoid the collar rot disease.

2) Sowing
500 g of seeds is required for planting one ha. June-September is the best season for planting.  Avoid planting in rainy season.

3) Nursery
Approach and epicotyl grafts are used for planting.

4) Planting
Plant the seedlings at 1.8 m either ways in pits of 45 cm x 45 cm x 45 cm size.

5) Irrigation
Irrigate copiously after planting. Irrigate the field once in a week.

Male trees should be removed after the emergence of inflorescence maintaining one male tree for every 20 female trees for proper fruitset. In each pit only one vigorously growing female/hermaphrodite tree should be retained and other plants should be removed. In gynodioecious type like (Co 3 & Co 7) keep one hermophrodite type/pit and remove female trees. 

Micronutrients
Spray ZnSO4 0.5% + H2BO3 0.1% during 4th and 8th month to increase growth and yield characters.

Nematodes
To control the nematode infestation in nursery, apply Carbofuran 3 G @ 1 g/polythene bag after germination.

Papaya ring spot virus
Grow maize as catch crop for vectors. Spray insecticides to control the vectors. Micronutrient spray at fortnight intervals.

Rootrot and wilt
In water stagnated areas root-rot may appear easily. It is advisable to drench the soil with 0.1 % Methoxyethyl mercuric chloride or 1 % Bordeaux mixture or Metalaxyl 0.2%, 2 or 4 times at fortnightly intervals. Good drainage is important to avoid the spread of disease.
