As moisture conditions become more limiting, the earlier-maturing hybrids will have greater yield reliability... Slower-maturing hybrids will generally give higher yields than quick-maturing hybrids when moisture and nutrients are not limiting... There are some hybrids that produce poor quantities of pollen (and are more susceptible to the disease) if flowering during cool conditions...

Honeydew oozing on a grain sorghum head caused by Claviceps africana (ergot)... Crops at greatest risk are: forage sorghums heads on ratoon crops flowering late in the season tillers on late-flowering plants crops in which pollination has been affected by a cold snap before or at flowering... To minimise the risk of ergot contamination, growers should: sow at recommended times ensure even flowering (use press wheels, high-germination seed, accurate seed depth control; good crop nutrition, wide row spacing (90-100 cm), especially with hybrids that tiller heavily, and consider pre-harvest kill-off of tillers using glyphosate herbicide) graze forage sorghum heavily to delay flowering until after grain sorghum has flowered...
