Other claims from this paper (15)
- Method / resource Core sampling at least 50 roots represents bulk root composition.
- Observation Commonly grown mangel strains can mostly be classified into five types.
- Association Four mangel types had nearly inverse cropping power and dry matter percentage and similar dry matter yield per acre.
- Association Larger roots contained more water than smaller roots.
- Association Larger roots contained less dry matter than smaller roots.
- Observation Mangel composition varied considerably among years, possibly with rainfall and sunshine.
- Intervention effect Manurial treatment produced distinct differences in mangel composition.
- Intervention effect Excess nitrogen delayed ripening.
- Intervention effect Excess nitrogen decreased dry matter percentage.
- Observation Roots grown on different farms differed in composition.
- Observation Individual roots of the same variety grown together varied in dry matter, sugar and nitrogen content.
- Observation Individual roots of the same variety grown together varied in size, shape and colour.
- Association Correlations among measured root characters were weak.
- Association Colour, shape and specific gravity of root or juice were uncorrelated with dry matter, sugar or nitrogen percentage.
- Recommendation Selection for colour, shape or specific gravity is unlikely to improve the desired composition.
