Sesame varieties have adapted to many soil types. The high-yielding crops thrive best on well-drained, fertile soils of medium texture and neutral pH. However, these have low tolerance for soils with high salt and water-logged conditions. Commercial sesame crops require 90 to 120 frost free days. Warm conditions above 23 °C favor growth and yields. While sesame crops can grow in poor soils, the best yields come from properly fertilized farms (https://en.wikipedia.org/wiki/Sesame)
