Meters equipped with the 12 cell acid-delinted hill-drop
cotton discs will plant from 3 to 6 seeds per cell because of
variations in cotton seed size.

Determine which hill spacing is desired and select the
transmission ratio that is closest to that hill spacing on the
chart.

To determine the average seeds per hill and hills per acre
do the following field check:

1.

Measure 1/1000 of an acre. (1/1000 acre = length of
row 17’5” for 30” widths).

2.

Multiply the average seed per hill by hills per acre.

Example:

4 seeds per hill x (13 hills x 1000) = 52,000

NOTE: See Planting Rates on page 15 for additional information. Always check seed population in the field to ensure
planting rates are correct.
