Other claims from this paper (8)
- Intervention effect Soybean after one year of corn yielded more than soybean after soybean.
- Intervention effect Two years of corn between soybean crops gave higher soybean yields than one year of corn in only 2 of 6 years.
- Intervention effect Yields in the corn-wheat/soybean double-cropping system were similar to monoculture soybean.
- Intervention effect No-till had positive or no effects on soybean yield early in the study.
- Intervention effect No-till soybean yielded less than conventionally tilled soybean after several years.
- Mechanism Yield loss of no-till soybean is attributed to greater weed pressure in no-till plots.
- Intervention effect Heterodera glycines population densities were greater in conventionally tilled plots than in no-till plots.
- Observation Heterodera glycines numbers fluctuated unpredictably from year to year.
