Agronomic Efficiency of Biosolid as Source of Nitrogen to Banana Plants

Figure 2

Biosolid and mineral fertilizer application on fruit yield (a) and agronomic efficiency index (b). Columns, within the same crop season, labelled with different letters on top are significantly different (). ns = not significant (). In (b) observe the difference of scale on -axis. , , and correspond to the equivalent amount of approximately 100, 200, and 400 kg ha⁻¹ year⁻¹ of N applied as SS. and were equivalent to the application of 200 and 400 kg ha⁻¹ year⁻¹ of N as NPK mineral fertilizer.
