Rhubarb. 



The most interesting plots of our rhubarb plantation have 

 given the following average results over four years. 



In the case of the small varieties, doubling the dung gave a 

 very large increase, but practically the same result was obtained 

 by supplementing the light dressing of dung with a moderate 

 dressing of chemical fertilisers. 



In the case of the coarse variety heavy dunging again largely

increased the crop, but a better and cheaper result was obtained 

 by combination of light dung and chemical fertilisers. In fact, 

 with the coarse variety, chemical fertilisers alone, at a com- 

 paratively small cost, did nearly as well as even the heavy dressing 

 of dung. 



With both kinds of rhubarb we have noticed, by examination 

 both in the kitchen and on the table, that the leaf-stalks pro- 

 duced on the plots receiving chemical fertilisers were, owing 

 probably to more rapid growth, much more tender and less 

 stringy than those grown with dung alone.
