    Default papaya ultivation

    Dear sir,
    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.



    5.5.2 Planting season



    Papaya is planted during spring (February-March), monsoon (June-July) and autumn (October-November).



    5.5.3 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.



    5.5.4 Planting Method



    The seedlings are planted in pits of 60x60x60 cm. size. In the summer months the pits are dug about a fortnight before planting. The pits are filled with top soil along with 20 kg. of farmyard manure., 1 kg. neem cake and 1 kg. bone meal. Tall and vigorous varieties are planted at greater spacing while medium and dwarf ones at closer spacing.



    5.6 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.



    5.6.1 Micronutrients



    Micro-nutrients viz. ZnSO4 (0.5%) and H2 BO3 (0.1%) are sprayed in order to increase growth and yield characters.







    5.7 Irrigation



    The irrigation schedule is fixed on the basis of soil type and weather conditions of the region. Protective irrigation is provided in the first year of planting. During the second year, irrigation is provided at fortnightly interval in winter and at an interval of 10 days in summer. Basin system of irrigation is mostly followed. In areas having low rainfall, sprinkler or drip system can be adopted.



    5.8 Intercultural Operations



    Deep hoeing is recommended during the first year to check weed growth. Weeding should be done on regular basis especially around the plants. Application of Fluchloralin or Alachlorin or Butachlorine (2.0 g./ha.) as pre-emergence herbicide two months after transplanting can effectively control the weeds for a period of four months. Earthing up is done before or after the onset of monsoon to avoid water-logging and also to help the plants to stand erect.



    5.9 Inter-cropping



    Intercropping leguminous crops after non-leguminous ones, shallow rooted crops after deep rooted ones are beneficial. No intercrops are taken after the onset of flowering stage.


    5.10 Removal of male plants

    About 10% of the male plants are kept in the orchards for good pollination where dioecious varieties are cultivated. As soon as the plants flower, the extra male plants are uprooted.

    5.11 Plant Protection Measures

    5.11.1 Insect Pests

    The insect pests mostly observed are fruit flies (Bactrocera cucurbitae), ak grasshopper (Poekilocerus pictus), aphids (Aphis gossypii), red spider mite (Tetranychus cinnabarinus), stem borer (Dasyses rugosellus) and grey weevil (Myllocerus viridans). In all cases the infected parts need to be destroyed along with application of prophylactic sprays of Dimethoate (0.3%) or methyl demeton (0.05%).

    5.11.2 Diseases


    The main diseases reported are powdery mildew (Oidium caricae), anthracnose (Colletotrichum gloeosporioides), damping off and stem rot. Application of wettable sulphur (1 g./l.) carbendazim/thiophanate methyl (1 g./l.) and Kavach/Mancozeb (2 g./l.) has been found to be effective in controlling the diseases.



    5.12 Harvesting and Yield



    Fruits are harvested when they are of full size, light green in colour with tinge of yellow at apical end. On ripening, fruits of certain varieties turn yellow while some of them remain green. When the latex ceases to be milky and become watery, the fruits are suitable for harvesting.



    The economic life of papaya plant is only 3 to 4 years. The yield varies widely according to variety, soil, climate and management of the orchard. The yield of 75-100 tonnes /ha. is obtained in a season from a papaya orchard depending on spacing and cultural practices.
