Cotton (Gossypium hirsutum) Cultivars Exhibiting Tolerance to the Reniform Nematode (Rotylenchulus reniformis)

Table 6

Effects of nematicide on seed cotton yield in four fields in a field study at the Delta Research and Extension Center in Stoneville, MS, in 2006 and 2007; data are averaged across cultivars.

Nematicide	Seed cotton yield (kg/ha)^x
	Field 4	Barn Field		Field 1		Field 12
No nematicide	1980.9	1897.7	b^y	2617.8	b^y	3369.4	b^y
Nematicide applied^z	1891.4	2030.6	a	3085.8	a	3546.1	a

^x Seed cotton yield taken from the middle two rows of subplots.
^y Means followed by the same letter in the same column are not significantly different at the 0.05 level based on ANOVA.
^z Aldicarb applied in furrow at planting (0.84 kg a.i./ha) plus side dress application at pinhead square (1.17 kg a.i./ha).
