Technical Abstract: A short season-high density strategy for dryland sorghum production was compared to standard dryland sorghum production practices over a 5 year period. For early to mid-June planting dates, yields were similar for the two strategies. However, for late season planting dates (late June - early July) the early maturity hybrid planted at 64,000 seed/acre on 15-inch rows shad average yields of 3070 lb/ac compared to 1650 lb/ac for a medium maturity hybrid planted in 30-rows at 32,000 seed/acre. Using the short season-high density strategy for late planting hastened maturity and helped avoid freeze damage. The short season-high density strategy for dryland sorghum production is not recommended for early to mid season planting dates due to problems with excessive lodging. Several early maturity sorghum hybrids were identified in the 1995 test that had high yield potential and good standability under conditions of high moisture stress and high density.
