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.
