History |
Datura, a 16th century name latinised from the Persian
and Arabic names for D. fastuosa. Stromonium was the
name of Datura metel L. at Venice in the middle of the
16th century, where it was cultivated; and the plant is
figured under that title by Tragus and Fuchsius. The
origin of the name is not evident, but many perhaps are
an italianised contraction of Greek Letters. D.
Stramonium seems to have been a later introduced into
Europe than D. metel but as it rapidly spread and became
a common plant the name of the latter was transferred to
it. |

Agrocultivation |
D. stramonium is
propagated through seeds. Seeds can be directly drilled
in furrows or the plant can be raised in nursery and
transplanted in the field. Transplanting gives better
results. In case of direct seedling, seeds are drilled
in rows at a distance of 45- 60cm. before preparation of
the field. The ideal time of seed sowing is March- April
in temperate areas where in case of north Indian plains
the seed are sown in November.
In case of
transplanting, the seeds are planted in raised nursery
beds consisting of farmyard manure and soil. After the
seeds are broadcasted, the bed is covered with a layer
of sand and farmyard manure. The bed should be kept
moist. After the seedling reach to certain heights (4- 6
weeks). They are transplanted in the field in May and
June in case of temperate areas and in November and
December in case of subtropical areas. The seedlings are
placed at the distance of 30- 45 cm in rows and 45- 60
cm. The field is ploughed and deseeds several times
before planting. Pre-planting irrigation should be given
before preparation of the field. The ideal time of seed
sowing is March- April in temperate areas where in case
of north Indian plains – the seeds are sown in November.

6 weeks), they are transplanted to the fields in May and
June in case of temperate areas and in November and
December in case of sub-tropical areas. The seedlings
are placed at the distance of 30- 45 cm in rows and 45-
60cm apart. |
