ripening. The leaves assume earlier and in greater number than on plot 1, a yellow 

 colour, and dry up mostly with a somewhat lighter colour. The collective 

 appearance is very well depicted by the coloured photographs. In such manuring 

 the beets are sound, sugar content normal, being sometimes somewhat increased. 



Table 20. 

 (Plot 6.) 



For this plot, with strong Nitrogen, Phosphoric Acid and Potash manuring, that 



which was said about the rigidly exact manuring in the pot experiments holds good 



here. The harm done by Nematodes is best overcome by this method. The 



development of the plant from the beginning is extraordinarily strong, only luxuriant 



dark green plants being seen until late summer. If the manuring is rightly measured, 



whic4i has to be reckoned on the number of Nematodes present, then the leaves 



become, when the weather is normal, finally yellow, and dry up in a brown colour, 



and a normal ripening results, although, if the weather is unfavourable, the ripening 



may be somewhat protracted. 



The beets remain healthy and the sugar content is normal. Even if the sugar 

 content is somewhat lessened by frequent protraction of ripening, it is always again 

 compensated for by the high yield of the beets.
