Evaluation of New Deltapine® Cotton Varieties

Each season a new set of candidate cotton varieties are introduced through the Deltapine® New Product Evaluator (NPE) program.
This study was conducted to evaluate the new products in the cotton production system at Scott, Mississippi.

Twelve Deltapine® cotton varieties were included in this study:
- DP 1614 B2RF
- DP 1916 B3XF
- DP 1518 B2XF
- DP 2012 B3XF
- DP 1823NR B2XF
- DP 1725 B2XF
- DP 2020 B3XF
- DP 2038 B3XF
- DP 2055 B3XF
- DP 1835 B3XF
- DP 1845 B3XF
- DP 1646 B2XF
Varieties were planted in strip plots 6 rows wide and 550 feet long, approximately 0.25 acre/plot.
Plant growth regulator was applied to all varieties as 4.2% a.i. mepiquat chloride, with a total of 38 oz applied at the following timings and rates:
- 7/14 at 10 oz/acre
- 8/7 at 12 oz/acre
- 8/30 at 16 oz/acre
All weed control, insect control, and irrigation inputs were applied per local standards.
Six rows were harvested for yield and lint samples were ginned using research gins at Scott, Mississippi to estimate turnout.

An average turnout of 42% was observed across the tested varieties (Figure 1).
Higher than expected yields were observed across this study. Of the 12 tested varieties, 9 varieties had calculated yields of greater than 4 bales/acre (greater than 1920 lb/acre). The trial average was 1997 lb/acre.
In this demonstration, the highest yield ever recorded at Scott Learning Center was harvested. DP 1646 B2XF yielded 2394 lb of lint/acre or 4.9875 bales/acre. This is likely a function of favorable weather, management, and yield potential, which were all greatly positive factors during 2019.

The NPE candidate varieties and current commercial Deltapine® products appeared to have very high yield potential in the Scott, Mississippi location during 2019.
Consult your local Bayer representatives for further information about variety placement and management for the 2020 season.
