Sorghum is mainly cultivated in drier areas, especially on shallow and heavy clay soils the production of sorghum in south africa varies from 100 000 ton (130 00 ha) to 180 000 ton (150 000 ha) per annum the free state and mpumalanga provinces are the largest contributors to the area planted to sorghum and sorghum production. Figure 32 leaf temperature among sorghum groups over time for sorghum 58 figure 33 minimum fluorescence values (fo) values among sorghum groups over the first three weeks after anthesis for sorghum lines 59 figure 34. (figure 4) the sorghum panicle development is complete and primed for flowering, and the plant has attained its maximum leaf area and accumulat-ed approximately 60 percent of its total dry matter severe drought stress at this time can impede pan-icle exertion from the boot and lead to incomplete flowering (anthesis), seed set and loss in grain.
