Black sesame originated in Africa, then was brought to Asia Minor (Babylon) and moved west - into Europe and south into Asia, gradually distributed to India and some South Asian countries, China. India is considered the distribution center of black sesame. In South America, black sesame was introduced from Africa after Europeans discovered it in America.

Currently, the world produces about 2 million tons of black sesame every year. In which the main growing regions are:
- Asia: Produces 55 - 60% of the world's output
- America: 18 - 20%
- Africa: 18 - 20%
In addition, Europe and Oceania also grow sporadically but not significantly.
Countries that grow a lot of sesame in the world:
- India: Leading the world with an output of about 4,000,000 tons/year.
- China is the second largest producer: 320,000 - 350,000 tons/year. In China, sesame is grown mainly in 4 provinces, Henan, Hubei, Anhui and Jiangxi, accounting for 78.1% of the country's sesame area, of which Hubei has the highest yield of 15.12 quintals/ha
- Sudan (Africa): 150,000 - 200,000 tons/year.
- Mexico (Americas): 150,000 - 180,000 tons/year.
Other countries with relatively large output are: Burma, Pakistan, Thailand (Asia); Nigeria, Tanzania, Uganda (Africa); Colombia, Venezuela (Americas).
In Vietnam, black sesame is a traditional agricultural product associated with the working life, cultural activities and beliefs of Vietnamese farmers from the past to the present. Black sesame is an oil crop with high economic value, short growing period, easy to grow, low maintenance, low investment capital. In particular, it is a drought-resistant crop, so it is chosen to convert crop structure in the current climate change conditions to achieve high economic efficiency per unit area.
Compared to rice, sesame has 5 times higher economic efficiency. In addition, sesame also has many nutrients that are very good for health and appear in many dishes of Vietnamese people. Therefore, black sesame is grown in all ecological regions of the country, however, its concentrated areas are in the provinces of North Central, South Central, Southeast and Central Highlands.
Growing black sesame also helps protect soil fertility, increase crop productivity and increase income per unit area of ​​agricultural land, gradually raising people's living standards to meet income criteria.
In Vietnam, sesame has been grown for the longest time in the North, but the area has not been expanded because the climate and soil conditions are not suitable for crop growth.
In An Giang province, the sesame growing area has now increased to 16,000 hectares. In Chau Phu, An Giang, the yield is from 400 - 600 kg/ha. If appropriate cultivation methods are applied, sesame yield can reach 1 - 1.2 tons/ha;
In Long An, there are currently about 1,300 hectares of black sesame, mainly grown in Tan Hung and Vinh Hung districts.
In Can Tho, there are about 5,000 hectares of black sesame, mainly grown in Thot Not and O Mon. The average yield is about 1-1.23 tons/ha.
Nghe An is a province with a large agricultural land area, the climate and soil conditions are very suitable for the development of black sesame, and is one of the provinces with a large sesame scale. Here, sesame is grown on sandy soil, coastal soil, mountainous soil, concentrated in some districts such as: Dien Chau, Nghi Loc, Nam Dan, Vinh City, Tan Ky, Quynh Luu ... in which the most is Dien Chau district, accounting for 50 - 60% of the total area of ​​the province; produced in all 3 crops: Winter-Spring, Summer-Autumn, Summer-Autumn. In 2019, the total planting area of ​​the province was 2,974.24 hectares, the average yield reached 7.41 quintals/ha, the output was 2,196.69 tons. Dak Lak has a large area of ​​agricultural and forestry land, the climate and soil conditions are very suitable for the development of black sesame. However, currently in Dak Lak, it is one of the provinces with a modest scale of black sesame cultivation in the country, only a few districts grow black sesame such as M'Dak (Cu Prao commune); Ea Kar district (Ea Sar commune, Ea So); Krong Pac district (Ea Phe commune, Vu Bon); especially farmers in Ea Sup district are successfully applying the model of intercropping sesame with winter-spring and summer-autumn rice, with more than 200 hectares of black sesame, distributed mainly in Ea Bung, Ea Le, Ya To Mot communes... for a yield of 1.2 tons/1 hectare of black sesame. The production investment cost is low, the cultivation technique is quite easy and suitable for local conditions, so the area applying the intercropping model of "2 rice crops, 1 sesame crop" in Ea Sup district is increasing. However, to expand the sesame growing areas in Ea Sup district, it is necessary to increase support for farmers on technical measures to care for this crop, especially sesame processing techniques after harvest to ensure product quality. However, the export value of black sesame in Dak Lak in particular and Vietnam in general is not high, not commensurate with the potential of the locality due to the traditional technical care process, the lack of synchronous mechanization in rice production, unselected varieties... Moreover, the market price of black sesame is unstable because farmers have not guaranteed output, and are often forced to lower prices by traders. With a relatively high economic value, the area of ​​black sesame is likely to expand in the near future. However, it is difficult to
