The major essential oil contents are located
in the leaves of mints. More the leaves, the better
is the yield from crops. The vegetative growth
for the higher production of leaves can be stimulated
by the application of essential plant nutrients
to the soil or to the plant directly. The recommended
fertilizer dose per hectare by CIMAP is as follows-
| During
land preparation |
During
planting |
1st dose
5 weeks after planting |
2nd dose
5 weeks after first application |
3 rd dose
immediately after harvest |
th 4 dose
5 weeks 3rd after application |

Foliar spray of urea @ 2% is also advisable especially
late in the season when top dressing of soil is
difficult. This technique should also be used
in the crops of mint grown in sandy soil. It is
also advisable to spray on foliage 0.5% FeEDTA
to promote photosynthetic capability of the leaves
by prevention of chlorosis.
