e0“M. cochinchinensis in 1993 and M. pruriens var. IRZ in 1995 had the highest ground cover rating early in the growing seasons”
e1“Inorganic fertilizer at30 kg ha- 1 each of N, P and K increased velvetbean ground cover by 2-22%, with M. cochinchinensis (14-22%) and M. pruriens var. IRZ (5-15%) showing the highest response in 1993 and 1995, respectively.”

Other claims from this paper (19)
- Observation M. cochinchinensis had the highest early ground cover in 1993 and showed a 14-22% fertilizer response.
- Observation M. pruriens var. utilis had the lowest ground cover and least fertilizer response in both years.
- Intervention effect Fertilizer increased velvetbean ground cover by 2-22%.
- Intervention effect M. pruriens var. utilis reduced speargrass shoot density by 50% after one season.
- Intervention effect M. cochinchinensis reduced speargrass shoot density by 76% after one season.
- Intervention effect M. pruriens var. IRZ reduced speargrass shoot density by 68% after one season.
- Intervention effect M. pruriens var. utilis reduced speargrass shoot dry matter by 72%.
- Intervention effect M. cochinchinensis reduced speargrass shoot dry matter by 92%.
- Intervention effect M. pruriens var. IRZ reduced speargrass shoot dry matter by 79%.
- Intervention effect Fertilizer reduced speargrass growth in velvetbean plots.
- Intervention effect Fertilizer increased speargrass growth in plots without velvetbean.
- Intervention effect Velvetbean residue suppressed speargrass until the subsequent cropping season began.
- Intervention effect Maize grown a year after velvetbean required 50% less weeding than maize without previous velvetbean.
- Intervention effect Maize shade reduced speargrass shoot growth by 30-80%.
- Observation Speargrass regrew four weeks before maize harvest.
- Intervention effect Maize grain yield was higher following velvetbean than without velvetbean.
- Association Speargrass shoot density negatively correlated with maize grain yield (r=-0.42, P<0.01).
- Association Speargrass dry matter negatively correlated with maize grain yield (r=-0.32, P<0.01).
- Mechanism Velvetbean has limited effects on speargrass rhizomes and consequently does not provide long-term control despite suppression during establishment and the next cropping phase.
