Nutritional disorders of grain sorghum

 

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.
