The Sesamum indicum crop
Sesamum indicum in Latin or the Sesame seed is known to be the oldest oil
seed crop. The sesame oilseed comes in a variety of species of which most
Sesamum indicum crop is an annual plant growing 50cm up to 100cm tall. The
plant has opposite leaves ranging from 4cm to 14cm long. The leaves are
broad up to 5cm and at the base of the plant its is narrowing to just 1 cm
measured on the flowering stem.
sesame flowers are yellow with a tubular shape, from 3cm up to 5cm long
with a four lobed shaped mouth. The color of the flowers vary in white,
yellow, purple or blue.
The sesame pod and seeds
pods is a capsule, pubescent and rectangular in shape and grooved with a
short triangular section. The pod’s length varies from 2cm to 8cm and its
width is between 0.5cm to 2 cm. The number of loculi ranges from 4 to 12.
When matured, the sesame pod dehisces to release the seeds by opening the
septa from top to bottom. The degree to which the dehiscence takes place is
important for mechanized harvesting as well as height of the first capsule.
seeds of the Sesame crop are small and the there is a great variety in
form, size, and colors. Most common is that the seeds are between 3 to 4mm
long x 2mm wide and 1mm thick. The seed cover called testa can be tabbed or
smooth. The weight of the sesame seeds is ranging from 20 to 40 milligrams.
The sesame seeds are shaped slightly flattened and ovate and slightly thinner
close to the eye of the seed (called the hilum) at the opposite end.
The sesame seed crop features
sesame see enjoys to be able to grow in areas where other crops are not
able to grow. Sesame crop is a robust crop that requires little farmer support
as it is able for example to grow in very dry conditions, with a high heat
and with just some residual moisture in the soil after the raining season
is gone or opposite when rains are still excessive. Sesame crop is grown by
farmers at the edge of the desert, where no other crop is able to grow.
Therefore, Sesame crop is also called a survivor crop.
the sesame crop is very tolerant to drought – mainly due to its extensive
root system – it does require an appropriate moisture for its germination
and its early growth. The sesame crop has no problem surviving excess water
or drought but it does affect yields which will be much lower in both
conditions. What impact yield most
is the moisture level just before planting and flowering.
