HulleD sesame sEED.......
Sesame is very drought-tolerant, in part due to its extensive root system. However, it requires adequate moisture for germination and early growth. While the crop survives drought, as well as presence of excess water, the yields are significantly lower in either conditions. Moisture levels before planting and flowering impact yield most.
Most commercial cultivars of sesame are intolerant of water-logging. Rainfall late in the season prolongs growth and increases high harvest-shattering losses. Wind can also cause shattering at harvest.
After harvesting, the seeds are usually cleaned and hulled. In some countries, once the seeds have been hulled, they are passed through an electronic colour-sorting machine that rejects any discolored seeds to ensure perfect colour. This is done because sesame seeds with consistent appearance are perceived to be of better quality by consumers, and sell for a higher price. Immature or off-sized seeds are removed and used for oil production.
