Nutritional disorders of grain sorghum locations
Aims

To present a handbook of diagnostic techniques for nutrient deficiencies and excesses in sorghum.

Key messages
  • Grain sorghum is the staple food of lowland farmers in semi-arid tropical areas of Africa and Asia, but crop yields are commonly less than 30% of those in developed countries.
  • Nutritional disorders frequently diminish yields because grain sorghum is grown in areas with impoverished soils and little fertiliser.
  • This handbook describes a range of micronutrients deficiencies and toxicities of grain sorghum, drawn from field work in India and glasshouse trails in Queensland.
  • The most common nutritional disorders observed in sorghum growing on alkaline soils are deficiencies of iron, zinc, and manganese.
  • The major nutritional problems for sorghum growing on acid soils are toxicities of aluminium, iron, and manganese, and deficiencies of phosphorus, calcium, magnesium, molybdenum, and zinc.
