Effect of Blended NPSB and Nitrogen Application rates on Growth, Yield, and Yield Components of Bread Wheat (Triticum aestivum L.) at Gitilo Dale Research Site of Wallaga University, Western Ethiopia

Table 4

Effects of NPSB and nitrogen fertilizer amounts on the bread wheat spike duration.

NPSB (kg ha^−1)	Spike length (cm)
	N (kg·ha^−1)
	0	31.1	71.65	112.2
0	5.49^g	5.87^f	6.15^e	6.36^d
100	6.30^de	6.30^de	6.42^d	6.66^c
150	6.31d^e	6.46^d	6.70^c	7.15^b
200	6.36^d	6.66^c	7.05^b	7.63^a
Lsd (5%)		0.194
CV (%)		1.80

The same letters that are superscripted are statistically equivalent at the 5% level of significance. Least significant difference (LSD) and CV = the coefficient of variance. NPSB = blend of nitrogen, phosphorus, sulphur, and boron.
