Table 5.
OPM∗ | Average time per 54 m cut run (s) | Standard deviation of time/run (s) | Harvest rate (s Mg-1) | Standard deviation rate (s Mg-1) | Tukey comparison group for harvest rate (p < 0.001) | Area of one run (ha) | Harvest speed (ha h-1) | Yield (t ha-1) | harvest rate (Mg h-1) | Mean bale weight (kg) |
---|---|---|---|---|---|---|---|---|---|---|
OPM-52 | 45 | 4.8 | 295 | 31.2 | a | 0.0243 | 0.52 | 6.3 | 12.1 | 590 |
OPM-53 | 42 | 3.4 | 273 | 21.9 | a | 0.0243 | 0.48 | 6.4 | 13.2 | 580 |
OPM-54 | 42 | 3.8 | 237 | 21.8 | b | 0.0243 | 0.48 | 7.2 | 15.1 | 580 |
Mxg | 48 | 5.2 | 166 | 16.7 | c | 0.0243 | 0.55 | 12.8 | 23.3 | 530 |
∗Stem diameters for OPM 12, 52, 53, 54 are approximately half those of Mxg but with high stem counts m-2.
