CHEMISTKY FEEDING VALUE.

The ash of the bulb and of the leaves contained in 100 

 parts 



In its mineral constituents, therefore, it very closely 

 resembles the turnip; and although the percentage of 

 mineral matter in the plants appears to be a little in excess 

 of that in the turnip, they are so nearly alike in quantity 

 as WBll as quality, that for all practical purposes they may 

 be taken as the same ; so that weight for weight per acre 

 the kohl-rabi cannot be looked upon as a more exhausting 

 crop to the soil. 



Its organic composition has just been determined by 

 Dr. Anderson, 1 whose investigation, from its very satis- 

 factory results, will no doubt have the effect of .securing 

 more attention to the crop than it has hitherto received. 



It is thus given : 



Bulbs. Tops. 



Nitrogen compounds (flesh-formers), 275 2'37 



Compounds destitute of nitrogen (heat-givers and fat-formers), '8'62 8'29 



fibre, -77 1-21 



Ash (mineral matter) T12 1'45 



Water, 8674 86'68

1 We are indebted to Messrs. Lawson of Edinburgh for the organic analysis 

 of the kohl-rabi. With their characteristic liberality they caused its feeding 

 properties to be thoroughly investigated before recommending it to the notice 

 of the agricultural public.
