|---|---|---|---|
| (g/plant) | (%) | (Kg m−2) | |
| Soil1 | - | - | 0.054c |
| OC | 0.60 b | 8.62 a | 2.38 b |
| OC + AS | 1.31 a | 7.71 b | 4.93 a |
| OC + AN | 1.16 a | 7.75 b | 4.71 a |
| Significance | ∗∗∗ | ∗∗∗ | ∗∗∗ |
Means followed by different letters within a column are significantly different. ∗, ∗∗, ∗∗∗ Significant at p < 0.05, 0.01 and 0.001 levels, respectively. NS = not significant. (OC- organic compost, OC + AS - organic compost +75 kg of N ha−1 applied as ammonium sulfate, OC + AN- organic compost +75 kg N ha-1 applied as ammonium nitrate).
Plant growth in soil treatment was not enough to collect leaf samples for analysis.
