Other claims from this paper (8)
- Observation Seed survival of Anoda cristata decreased to 25% after 35 months.
- Intervention effect At later times, seed survival was lower for seeds placed on the soil surface than for buried seeds.
- Observation Seed predation rates of Anoda cristata ranged between 0.3% and 6.7% per day.
- Intervention effect Seed predation was higher in non-tillage plots of the wheat/soyabean rotation from January to July.
- Intervention effect No significant difference in seed predation between tillage systems in soyabean monoculture.
- Intervention effect No difference in seed predation rates between planting densities.
- Mechanism Higher crop residue levels were the dominant factor influencing seed predation in non-tillage wheat/soyabean plots.
- Method / resource A polynomial regression of predation rate with time gave the best representation of seed predation among the models tested.
