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.

|Soil Type||Commerce silt loam||Harvest Date||10/9/19
- 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.
UNDERSTANDING THE RESULTS
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.
