Cost of cultivation depends on a various factors and cannot be provided. WHere are you locaqted??? REd lady is the bet variety.
Agro-climatic requirements
Papaya being a tropical fruit grows well in the mild sub-tropical regions of the country upto 1,000 m. above sea level. Night temperature below 120-140 C for several hours during winter season affects its growth and production severely. It is very much sensitive to frost, strong winds and water stagnation.
Deep, well drained sandy loam soil is ideal for cultivation of papaya.
Land Preparation
A well-drained upland is selected for cultivation. In open and high lying areas plants are exposed to strong winds or storm. Therefore, for proper establishment of papaya plantation, suitable wind break should be planted at the orchard boundary.
5.5 Planting
5.5.1 Planting Material
Papaya is commercially propagated by seed and tissue culture plants. The seed rate is 250-300 g./ha. The seedlings can be raised in nursery beds 3m. long, 1m. wide and 10 cm. high as well as in pots or polythene bags. The seeds after being treated with 0.1% Monosan (phenyl mercuric acetate), ceresan etc. are sown 1 cm. deep in rows 10 cm. apart and covered with fine compost or leaf mould. Light irrigation is provided during the morning hours. The nursery beds are covered with polythene sheets or dry paddy straw to protect the seedlings. About 15-20 cm. tall seedlings are chosen for planting in about two months.
Planting season
Papaya is planted during spring (February-March), monsoon (June-July) and autumn (October-November).
Spacing
A spacing of 1.8 x 1.8 m. is normally followed. However higher density cultivation with spacing of 1.5 x 1.5 m./ha enhances the returns to the farmer and is recommended.
High Density Planting : A closer spacing of 1.2 x 1.2 m. for cv. Pusha Nanha is adopted for high density planting, accommodating 6,400 plants/ha.
Nutrition
Papaya plant needs heavy doses of manures and fertilizers. Apart from the basal dose of manures (@ 10 kg./plant) applied in the pits, 200-250 g. each of N, P2O5 and K2O are recommended for getting high yield. Application of 200 g. N is optimum for fruit yield but papain yield increases with increase in N upto 300 g.
Micronutrients
Micro-nutrients viz. ZnSO4 (0.5%) and H2 BO3 (0.1%) are sprayed in order to increase growth and yield characters.
