Other claims from this paper (15)
- Intervention effect Dry matter yield rose with density to about 4 plants per sq.m., then changed little.
- Intervention effect Average plant weight declined with closer spacing.
- Observation Unstopped sprout yield peaked at about 1 plant per sq.m.
- Observation Marketable sprout yield peaked at about 2 plants per sq.m.
- Observation Marketable sprout number peaked at about 2 plants per sq.m.
- Intervention effect High-density plants were taller and more slender.
- Intervention effect High-density sprouts were more uniform.
- Intervention effect High-density plants had fewer thick roots.
- Intervention effect At widest spacing, roots per area declined.
- Intervention effect Planting pattern slightly influenced low-density plant height.
- Intervention effect Row orientations had negligible differential effects.
- Intervention effect Stopping greatly increased total sprout yield at all densities.
- Intervention effect Stopped plants had more marketable sprouts, especially above 3 plants per sq.m.
- Intervention effect Late October harvest increased sprout yield versus late September at all but lowest density.
- Observation Plant fresh weight declined during the later harvest interval.
