Table 2. Effect of tillage on soil water storage and water storage efficiency during the summer fallow seasons in 2014/2015, 2015/2016 and 2016/2017.
| Year | Tillage methods | Pf (mm) | Soil water storage (mm) | PSEf (%) | ||
|---|---|---|---|---|---|---|
| Pre-harvest | sowing | SWSf | ||||
| 2014/2015 | NT | 365.6 | 391.3 | 499.6 b | 108.3 b | 29.62 c |
| (Normal) | DP | 541.7 a | 150.4 a | 41.13 b | ||
| 2015/2016 | NT | 94.7 | 363.2 | 385.3 e | 22.1 e | 23.31 d |
| (Dry) | DP | 409.7 d | 46.5 d | 49.13 a | ||
| 2016/2017 | NT | 165.4 | 375.1 | 417.4 d | 42.3 d | 25.63 cd |
| (Dry) | DP | 453.2 c | 78.1 c | 47.28 a | ||
Note:
No tillage (NT), and deep ploughing (DP). Precipitation during the fallow period (Pf), soil water storage during summer fallow (SWSf), and precipitation storage efficiency during summer fallow (PSEf). Means within the same column with different lower letters were statistically significant at the critical probability levels of 0.05.
