Other claims from this paper (11)
- Intervention effect Narrow rows yielded more than wide rows.
- Intervention effect June planting yielded more than July planting.
- Observation June planting with 0.5 m rows yielded 2.99 Mg per hectare at density 38.
- Observation June planting with 1.0 m rows yielded 1.97 Mg per hectare at density 13.
- Observation July planting with 0.5 m rows yielded 2.45 Mg per hectare at density 51.
- Observation July planting with 1.0 m rows yielded 1.53 Mg per hectare at density 26.
- Intervention effect Higher density increased main stem length.
- Intervention effect Higher density decreased other plant components.
- Intervention effect Higher density produced a net branch stem yield loss.
- Recommendation Higher density was necessary for maximum late planted yield at narrow spacing.
- Observation Wide rows had much lower yield and lower responsiveness to density.
