Sorghum requires about 26-30oC temperature for good growth. The minimum temperature for the germination of the sorghum seed is 7 to 10oC. Grain sorghum does not germinate and grow well under cool soil conditions. Poor emergence and seedling growth may result if planted before soil temperatures reach 35oC.
