Table 7. Field trial LS meansz from 2019 and 2020 representing profit mean ($/ha), and lower and upper profit determined by ANOVA (P ≤ 0.10) for fertilizer and nematicide combinations on DP 1646 B2XFy at the Plant Breeding Unit.

No	Treatments	Mean profit		Lower profit	Upper profit	Additional fertilizer and nematicide input costx
Notes: Revenue was calculated using prices determine by the United States Department of Agriculture upland cotton announcement of $1.32/ha in 2019 and $1.54/ha in 2020. Profit was calculated by subtracting additional input costs ($/ha) from revenue. zLS-means followed by the same letter are not significantly different at P ≤ 0.10 as determined by ANOVA. Lower and upper profits are the 90% confidence levels. yAll DP 1646 B2XF seeds were pretreated with a BASF fungicide and insecticide metalaxyl, pyraclostrobin, myclobutanil, imidacloprid, and fluxapyroxad. xAdditional input costs from 2019 and 2020 were averaged to determine a single input cost for treatment analysis. wPHS refers to the pinhead square plant growth stage, when the first additional combination of fertilizers and nematicides were applied. vST refers to nematicide seed treatment, Aeris® (Thiodicarb) applied in 2019 and COPeO™ Prime (Fluopyram) applied in 2020. uFB refers to the first bloom plant growth stage, when the second combination of additional fertilizers and nematicides were applied.
