The objective of this experiment was to evaluate the yield response of current and new Deltapine® cotton varieties to seed spacing.
Research Site Details
Deltapine® cotton varieties planted:
— DP 1725 B2XF
— DP 1835 B3XF
— DP 1840 B3XF
— DP 1851 B3XF
Number of seeds per foot of row:
Plots were single strip trials that were 8-12 rows wide and 500 feet long.
All agronomic practices were per local standards.
Understanding the Results
In this study, average lint yields were generally greater when seeds were planted at 2.5 to 3.5 seeds/ft of a row with the lowest yield observed at 4.5 seeds/ft of a row, with the exception of DP 1646 B2XF.
Average yields for DP 1646 B2XF were inconsistent from 2.5 to 4.5 seeds/ft of row
What Does This Mean for Your Farm?
Cotton growers in the upper Southeast typically plant seeds at a rate of 2 to 3 seeds/ft of a row, regardless of row width; this study helps confirm that this seed spacing is ideal for most situations.
