Cultivation
Planting
The
plants of Jackfruit should be planted in a square system (hexagonal if the soil
is less fertile) 12m apart. June–August is ideal time for planting. The tap
root system along with plants should not be disturbed while planting. The young
plants should be protected from stray goats and cattle. Protective irrigations
are necessary initially at 12–15 days intervals depending on soil and
climatic conditions. The plants should be trained by removing lower branches.
Manuring
and fertilization
Its
plants need adequate nutrition for regular and good cropping. Apply 80kg
farmyard manure to a tree annually along with chemical fertilizers. For
obtaining higher productivity, the following fertiliser schedule is recommended
(Table ).

Harvesting and Postharvest management
Seedling trees start bearing from seventh to
eighth year onwards while the grafted ones from third year, when a few fruits
may develop. Singapore variety starts yielding from third year of planting. The
tree attains its peak bearing stage in about 15–16 years of planting. At this
stage, normally a tree bears up to 250 fruits annually with annual fluctuations
in yield. The weight of fruits also varies depending on the type. On an average
about 40–50 tonnes of fruits/ha could be obtained.
