Other claims from this paper (11)
- Intervention effect Intercropping reduced FS-16 sorghum yield by 14%.
- Intervention effect Intercropping reduced BR-44 sorghum yield by 74%.
- Intervention effect Intercropping changed sorghum yield-component response to population.
- Observation BR-44 mixtures had greater yield-component reductions than FS-16 mixtures, especially heads per plant.
- Intervention effect Intercropping reduced compensation of sorghum yield components across populations.
- Association Tillering and population density chiefly determined grain yield in mixtures.
- Observation FS-16 monoculture yield peaked above 25 plants per square metre.
- Observation BR-44 monoculture yield peaked at 12 to 15 plants per square metre.
- Intervention effect Intercropping soybeans with FS-16 reduced soybean yield by 75%.
- Intervention effect Intercropping soybeans with BR-44 reduced soybean yield by 17%.
- Recommendation Relative yield curves favored soybean spacing of 5 cm with sorghum at 5 plants per square metre.
