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 5

The main determinants of the number of kernels per spike of bread wheat are NPSB and nitrogen fertilizer levels.

Treatment	Number of kernels per spike
NPSB·kg·ha^−1
0	34.51^c
100	38.44^b
150	39.90^b
200	44.27^a
Lsd (5%)	1.87
CV (%)	5.70
N·kg·ha^−1
0	35.70^d
31.1	37.90^c
71.65	40.56^b
112.2	42.94^a
Lsd (5%)	1.87
CV (%)	5.70

In the table above, 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.
