Site selection and land preparation for sorghum production
Sorghum grows well in well-drained soils with moderate fertility. It can grow
in sandy, loamy, or clay soils, but not on heavy clay. The site should have good
exposure to sunlight. Sorghum does not grow well in waterlogged areas. The
crop is well adapted to temperatures ranging from 25 ℃ to 32 ℃ and rainfall of
400 - 600 mm per year. Too much rain can cause poor growth and the outbreak of
diseases. The crop grows well at altitudes between 500 and 1,500 metres above
sea level.

Land for sorghum production should be well prepared in advance of the onset
of rainfall to support easy planting and health crop growth. Clear all bushes and
weeds, and then plough to loosen the soil and improve drainage. The land should
be levelled to allow even distribution of water. Proper land preparation ensures
uniform crop establishment, vigorous plant growth and reduce weeds, soil-borne
pests, and soil-related diseases.
