Variation in the Chemical Composition of Mangels

T. B. Wood; R. A. Berry The Journal of Agricultural Science 1905. doi:10.1017/s0021859600000241

Other claims from this paper (15)

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.
Observation Long Bed yielded considerably more dry matter per acre than four other varieties.
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.
