SUBI Diseases and Nitrogen Deficiency

Researchers plant sweet sorghum.

Excessive nitrogen has been found to reduce syrup quality in sweet sorghum. Recommended amounts of nitrogen should not be exceeded, and all nitrogen should be applied before the crop is 30 inches tall. When sweet sorghum is grown immediately behind a legume crop, the nitrogen application rate can be reduced or eliminated without harming yields. Otherwise, a nitrogen rate of 40 pounds per acre is recommended. Avoid planting sorghum in fields where poultry litter has recently been applied, because soil nitrogen will be excessive.
