An analysis of the potential and importance of papaya farming in Bangladesh shows it is a nutritious fruit that can play an important role in the country's agriculture and nutrition security. There is also an opportunity to earn foreign currency by exporting papaya grown in Bangladesh. Papaya is rich in vitamins A and C and the enzyme papain, which aids digestion and boosts immunity.

So it is very important for farmers to give attention to papaya farming. Zinc, boron and magnesium are especially important for the health and yield of papaya plants. But without knowing the right amounts, they can also do harm. Here is how much to apply each year, and how.

Zinc prevents leaves from turning yellow and keeps growth normal. Apply 5-10 g of zinc sulphate per plant to the soil each year, split into 2-3 doses. As a spray, use 0.5-1 g per litre of water, 3-4 times before flowering and fruit set.

Boron prevents fruit cracking and misshapen fruit. Apply 2-4 g of borax or boric acid per plant to the soil each year, split into two doses. As a spray, use 0.5 g per litre of water, twice: at flowering and after fruit set.

Magnesium corrects yellowing of leaves (chlorosis). Apply 100-200 g of magnesium per plant to the soil each year, split into four doses, 50 g every three months. As a spray, use 5 g per litre of water, once a month when yellow leaves appear.

Apply zinc and boron before flowering and during fruit set. Apply magnesium to the soil after rain or irrigation. Spray in the morning or afternoon, not in strong sun.

Caution: overuse can harm the plant. Boron in particular causes toxicity, so never exceed the stated amount.

Bangladeshi farmers have huge potential in papaya farming. Papaya leaves and green fruit are used in the pharmaceutical industry, and the leaves in particular play an effective role in treating dengue fever. With proper training, modern technology and marketing opportunities, papaya can play an important role in the farm economy.
