Salt peter for mango flowering

Potassium Nitrate (KNO3),
induces flowering of the mango tree even out of season. This
is effective if the buds are plentiful and the leaves are
brittle and dark green.

 

Formula for
spraying:

10 grams potassium nitrate
for every liter of water

Or 200 grams (KNO3) for
every can (kerosene can)
water

The tree will bear fruit from
the 7-14 days spraying. If no flowers come, spray
again.
If rains after spraying, or the
tree does not flower after 15 days, repeat the
spraying.
If the flowers are abundant but
damaged by the leaf hoppers, spray again after 47-54
days.
Potassium nitrate that is not
pure is dangerous to the plant. Avoid using this if there is
no assurance that the KNO3 is pure. It is also necessary to get
permission from the authorities to use this fertilizer. If
permission is not given, use any of the commercial flower
inducers like:

Agriblum, Rebloom,
Manovit, Mangotone, Miracle blum, Flower Set.
