Table 2. Microplot LS meansz from 2019 and 2020 of the effect of additional nematicide and fertilizer combinations on DP 1646 B2 XFy plant height, cotton root fresh weight at pinhead square (PHS) and first bloom (FB), Rotylenchulus reniformis eggs per gram of root at PHS and FB sample data summed, and seed cotton yield at the Plant Science Research Center.

No	Treatments	Plant height (cm)	Root fresh weight (g) PHSx + FBw	R. reniformis eggs/g root-PHS + FB		Seed cotton yield (g)
Notes: zLS-means followed by the same letter are not significantly different at P ≤ 0.10 as determined by the Tukey Kramer method. yAll DP 1646 B2XF seeds were pretreated with a company fungicide and insecticide metalaxyl, pyraclostrobin, myclobutanil, imidacloprid, and fluxapyroxad. xPHS refers to the pinhead square plant growth stage when the first additional combination of fertilizers and nematicides were applied. wFB refers to the first bloom plant growth stage when the second 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.
