Timing and Application Rate for Sequential Applications of Glufosinate are Critical for Maximizing Control of Annual Weeds in LibertyLink® Soybean

Table 8

Soybean grain yield for the main effects of glufosinate rate and sequential application timing, averaged over the other factors in Fayetteville, AR, in 2015, 2016, and 2017.

Main effect	Level	Yield^b (kg ha^−1)
Glufosinate rate^c	451	2526	b
	595	2620	b
	738	2526	b
	882	2762	a
Sequential application timing	None	2324	d
	7 DAI	2701	ab
	10 DAI	3949	a
	14 DAI	2661	bc
	21 DAI	2526	c

DAI, days after initial application. ^bFor a given main effect, means within a column followed by the same letter are not different according to Fisher’s protected LSD (α = 0.05). ^cGlufosinate rates are in g ai ha⁻¹.
