Other claims from this paper (15)
- Intervention effect Soybean seed yield at 333,000 plants/ha exceeded that at 400,000 plants/ha, which exceeded 200,000 plants/ha.
- Intervention effect Soybean density beyond 333,000 plants/ha reduced sorghum yield.
- Observation All tested intercrops had land equivalent ratios above unity.
- Observation All tested intercrops had area-time equivalency ratios above unity.
- Association Land equivalent ratio declined with soybean density.
- Observation Area-time equivalency ratio peaked at 333,000 plants/ha.
- Observation Aggressivity at 200,000 plants/ha was consistently negative with mean −0.25.
- Observation Aggressivity varied inconsistently at the two higher densities.
- Association Soybean competitive ratio increased with soybean density from 0.76 to 1.15.
- Association Sorghum competitive ratio had the opposite response, from 1.23 to 0.76.
- Observation Relative crowding coefficient was inconsistent across densities.
- Observation Land equivalent coefficient exceeded 0.25 in all combinations.
- Observation Soybean yield equivalent peaked at 333,000 plants/ha at 1.70.
- Observation Dominance analysis found sole crop treatments dominated.
- Intervention effect Intercropped soybean at 333,000 and 400,000 plants/ha gave higher net benefits than at 200,000 plants/ha.
