How to grow sorghum (grain)

Sorghum is the fifth most important grain in the world. The United States is the number one producer of sorghum followed by India, Nigeria, and Mexico. The largest exporters are the United States, Argentina, and Australia. The latter countries account for 93% to 97% of all exports(2012). The plant was domesticated in the Sudan. In West Africa, it is known as  great millet, kafir corn, or guinea corn. It is an important staple food in Africa, but in the US it is used as cattle feed.

This article focus on grain sorghum, which is used for food and alcoholic beverages.

Weed competes with the sorghum plant for nutrients. so try to keep weeds out of the area. One can use herbicides (Dual or Lasso, Atrazine, Banvel,  Buctril , 2,4-D). Sorghum loves nitrogen soil. If pH falls below 6, the soil is too acidic and needs to be  neutralize by adding lime. It will not grow below a pH of 5.5. Sorghum can grow in arid soil. Temperature should be at or above 65°F or 18.3°C,  2 inches(5.08 cm) below the soil surface. Seeds should be planted .75 to 1.5 inches. When soils are cool and wet it should be planted .75 to 1.5, (1.9 cm to 3.81 cm) when it gets hotter 1.5 inches. Seeds should be planted 15 cm apart or 5.9 inches.

When the sorghum leaf turns yellow it is time to havest or the seed stalk turns from green to brown. Seeds can be removed by rolling the seed stalk on a flat surface.
