Effect of Cultivar and Planting Date on Soybean Response to Dicamba

Table 6

Relative yield of soybean at four planting dates averaged over a low-dose dicamba exposure at V3, R1, and V3 followed by R1 stage of soybean.

Planting date	Relative yield (%)^a
April	103 a
May	101 a
June	80 a
July	39 b

^aMeans within a row followed by the same lowercase letter are not different according to multiple comparison analysis α = 0.05 [14]. Yield of the nontreated check reported in kg·ha⁻¹ by month as follows: 3670, 3550, 5130, 3420 for April, May, June, and July, respectively.
