Land Preparing:

Bed system is the best method for papaya plant cultivation. At first plow the land with a ladder.  Make a drain in between two beds. The width of the drain should be 30 cm. Prepare the bed before pit preparation.

Propagation:

Papaya plant propagated through seeds. To raise seedlings at first, soak the selected seeds in water for several hours before sowing. The seed should be free from diseases and pests. Then sow seeds in 10 cm apart rows in seedbeds at 3-4 cm distance and 1.0-1.5 cm depth.  You can also use polybag for seed sowing. 2-3 seeds should be sown in one polybag. After germination, keep only the best one seedlings in one polybag.

Number of Seedlings:

Generally, 7500 seedlings are required for per hectare.

Pit Preparation:

Prepare pits of   60×60×45 cm at 2 m apart in the beds (2 × 2 m spacing).  Mix fertilizer like cow-dung 15 kg, TSP 500g, gypsum 250g, boric acid 20 g, zinc sulfate 20 g are to be applied per pit with the soil of the pit. Fertilizer should be applied in the pit at least 10-15 days before implanting.

The Ideal Time for Seed Sowing:

There are two seasons of sowing seeds of the papaya plant. September-October and December-January are the ideal seasons for seed sowing. When seedlings are 40-50 days old, they are ready for transplanting.

Transplanting Method:

Implant three seedlings in each pit at 30 cm distance in triangular form. Remove the polybag carefully without disturbing the ball. Implant the seedlings in the same depth as it was in the seedbed or in the polybag. If you want to follow monoecious method then implant only one seedling per pit.

Tendance:

Applying Fertilizer:

Apply 450-500 g urea and 450-500g MP for per pit. Apply 50 g urea and 50 g MP through top dress method at an interval of one month. First, apply fertilizer after one month of transplanting of seedlings. A double dose of fertilizer should be applied when the plant starts flowering. In dry season must give irrigation using top dressing method.

Irrigation and Drainage:

In dry season frequent irrigation is needed for papaya plant. The interval of two irrigations varies based on soil type and weather condition. Give irrigation at an interval of 10-12 days in winter and 6-7 days in the summer season. Make sure that the drainage system is well enough that there is no waterlogging in the rainy season.

Weed Control:

Keep the land always free from weed. Weed out the weeds with Hasua’ or lawn mower without loosening the soil especially in rainy season.

Removal of Extra Plants:

After teeming keep only the best female plant and remove other two trees from the pit. One male plant should be kept for every 10-15 female plants.

Thinning:

Generally, papaya plant bears 2-3 fruits per cluster. Keep only one fruit and thin out the extra fruits. In the 2nd year or flowering year when fruit-bearing is really high, the small fruits should be pruned out.

Pole Giving:

When tree bears more fruits, the upper part of the tree becomes very heavy. To balance the tree infix a strong pole for per tree and tie the tree with the pole. This pole also protects trees from the storm.

Disease & Pest Control:

Damping off and collar rot:

A serious disease of papaya due to the damp growing condition in seedbeds. It can cause severe damage in the rainy season. To control this disease treatment seed with Vitavax or Captan @ 2-3 g per kg of seed. To sterilize the seedbed spread a 6cm thick layer of sawdust or rice hull on it and burn it.

 Anthracnose:

It is a disease of papaya fruit. Brown lesions appear on fruits due to the attack of this diseases. To control spray Knowin or Topsin @ 2 g/L 2-3 times at 10-15 days interval.

Mealybug:

It sucks on leaves, fruits. For this the tree becomes weak. Apply Dimethoate 40EC (Perfecthion/ Taphgar) @ 2 ml/L 2-3 times at 15 days interval.

Nematode:

It a reason for root-knot in papaya. Apply Furadan 3G @ 5g per pit. Crop rotation is a prevention system for the nematode.

Nutrient Deficiency Problem:

B Deficiency:

Papaya highly needs vitamin B. B deficiency cause curling of leaves,  secretion of latex from developing fruits and deformation of fruits. Apply boric acid @ 20 g/pit and spray boric acid @ 2 g/L 2-3 times at 10-15 days interval.

S Deficiency:

Due to S deficiency leaves turn yellow, the plants become weak and stunted growth becomes slow. To manage, spray Thiovit or Cumulas @ 2 g/L 2-3 times at 10-15 days interval.

Zn Deficiency:

Due to Zn deficiency tree color turns mixed of white-green.   White net-like appearance may found on leaf venation. To cure of spray ZnO to leaves @ 2g/L 2-3 times at 10-15 days interval.

Harvesting:

Collect fruits when the latex of the fruits become almost watery. If you want to sell it in the local market then collect the fruits when they are half ripe. Generally, you can collect the first fruits after 12-14 months of implanting. Harvest fruits in the morning.

Post-Harvesting Practices:

To preserve dip the fruits in hot water at 550 C for 5 minutes. Then wrap each fruit separately with paper and preserve them in wooden boxes. Fill the boxes with straw, sawdust and other such soft material. It will protect the fruits from transportation injuries.
