Weed Control and Corn (Zea mays) Response to Planting Pattern and Herbicide Program with High Seeding Rates in North Carolina

Table 4

Influence of planting pattern on corn grain yield during 2012 at Lewiston-Woodville.

Planting pattern^a	Corn grain yield^b
	Field 1	Field 2
	kg ha^−1
Single row	4830^b	3150^a
Twin row	5400^a	3120^a

^aSingle rows consisted of planting corn on 91 cm centers. Twin rows consisted of planting corn in rows spaced 20 cm apart on 91 cm centers. In-row seeding rate adjusted to establish the same plant population for both planting patterns.
^bMeans within a field followed by the same letter are not significantly different at . Data are pooled over herbicide programs.
