Table 5. Effect of polypropylene mulching treatments on weed yield, manpower required of mulching test field and weeding
Treatment | MRMz test field (person/100m2/day) | MRWy (person/100m2/day) | Weed yield (dry weight, g/ 100m2) |
60g/m2 overlapping | 2.1 | 2.2 | 10.0±5.0c |
60g/m2 hole drilling | 1.3 | 2.2 | 18.3±7.6bc |
80g/m2 overlapping | 1.8 | 1.5 | 11.7±2.9c |
80g/m2 hole drilling | 1.4 | 1.5 | 23.7±1.2b |
Control | 0.8 | 4 | 40.0±8.7a |
Manpower required of mulching
Manpower required of weeding.
Data are the Mean±SE from the three replicates. Difference letters indicate treatments are significant difference at p<0.05 by Ducan's multiple range test.
