Other claims from this paper (12)
- Association Plant population greatly influenced sugar beet yields.
- Association Irrigation influenced sugar beet yields relatively little on average.
- Intervention effect Nitrogen rates of 0·6 to 1·2 cwt/acre N gave the largest sugar yield in all years.
- Intervention effect Populations of 17000 to 32000 plants per acre gave the largest sugar yield in all years.
- Intervention effect More nitrogen changed sugar yield little in any year.
- Intervention effect Increasing plant population changed sugar yield little in any year.
- Intervention effect Irrigation benefited sugar beet yield in only two of five years.
- Association Sugar yield had a linear relation with root dry-matter yield.
- Intervention effect Total dry matter was greatest at the highest planting density, nitrogen dressing and irrigation.
- Intervention effect Larger plant population decreased the share of dry matter in roots.
- Intervention effect Higher nitrogen dressing decreased the share of dry matter in roots.
- Intervention effect Irrigation decreased the share of dry matter in roots.
