Papaya Grower’s Tips

1. Is Phosphorus important for papaya?

    • Phosphorus is important for the papaya growing, it helps the development of an active root system, and in flower initiation and fruit set.
    • For soil with low pH and high soil iron levels, particularly in leached red soils can reduce phosphorus availability.
    • P deficient trees bear fewer fruits and hence suggested that P has an effect on setting the fruit. Plants raised on P deficient nutritive solution resulted in P deficiency symptoms initially in the oldest leaves, which have amottled yellow color along the edges. As deficiency progresses, the yellow areas become necrotic and the leaves have pointed lobes while the edges curl upwards.
    • Hence, a more soluble and available source of P is recommended to handle the P requirements.
    • Solutions:
      – NIFOSK S Series
      – High content of soluble P
    • NISOL Soluble Yellow 10-50-10+TE
      – High P formula.
      – Suitable to enhance the flowering.

    2. Why my papaya fruit become deformed and lumpy?

      • Reasons:
        – On papaya, symptoms of boron deficiency usually start when fruit are young, but it is on the mature fruit that they become most obvious. Fruits are deformed, plants are stunted and leaves are brittle and claw-like.
        – When fruit develop, they are likely to secrete a white latex. Later, the fruit become deformed and lumpy. The deformation is very probably the result of incomplete fertilization as most of the seed in the seed cavity are either abortive, poorly developed, or absent. If the symptoms begin when the fruit are very small, then most do not grow to full size.

      • Solutions:
      • NicalBo
        – Ca strengthens the fruit cell wall and reduces the risk of fruit cracking. Additional B playing role like glue to make sure the fruit is stronger to avoid crack.
        – Fast dissolved to supply quick Ca & B during peak growth of fruits.

      3. How to I handle drought season for my papaya trees?

        • Watering is the most critical aspect in raising papayas. The plants should be kept on to the dry side to avoid root rot, but also need enough water to support their large leaves.
        • Papaya plants produce more and bigger fruits if they are received sufficient water, else the flowers will drop off if they do not get enough water.
        • Drought stress damages the plants at the vegetative level and limits the reproductive development. Stomata closure is the initial response to drought, and this inhibits physiological and biochemical responses in plants. Moreover, this process alters the developmental process by driving plants to adopt a defensive state where plant productivity is hindered.
        • Extracts of Ascophyllum nodosum seaweeds are largely used to reduce the harmful effects of abiotic stress and enhance plant growth. The chemical composition of these seaweeds is mainly fatty acids, phytohormones, vitamins, mineral nutrients, and polysaccharides.
        • Solution:
          – Almino
          1. Contains extracts of Ascophyllum nodosum seaweeds, it has been shown to contain phytohormones—inorganic and organic components that act against the harshness of drought stress and enhance crop production and yield.
          2. Contains Amino Acid, it can play different roles in plants, such as stress-reducing agents, shortcut for nutrient source and hormone precursors.

        4. Will papaya tree grow well on waterlogged or harden soil condition?

          • Papaya crop flowers best in bright environment in porous soil with moisture in hot weather. Papaya plants grow best in near neutral soil pH (between pH 6.0 and 7.0). Soil types with adequate drainage is well suited for good growth and development of Papayas.
          • Poor soil condition such as waterlogged and harden soil conditions can lead to root diseases. Organic material may be added to the soil for better root development.
          • Fulvic acid is one of the components of humic substances generally obtained from humic soil. Fulvic acid has the effect of facilitating the absorption of fertilizer by plants and improving the soil environment.
          • Soil aggregation is promoted by fulvic acid mediating iron and aluminum, one of the constituents of the soil particles, to bind the soil particles together.
          • Solution:
          •  Fulvita Soluble
            – Fully water-soluble micro-molecule fulvic acid, easily combined with nutrients and transferred into plants.
          • Fulvita Granular
