Cabbages for Stock-Feeding.

The soil upon which the crop of this season was planted was a rather 

 heavy phase of Dunkirk clay loam. It seemed to be deficient in organic 

 matter and the supply of available moisture was not always sufficient or 

 constant. These factors tend to lower the yield for this season as com- 

 pared with last. 



Crop of 1906. 



These figures bring out several facts worthy of note. In yield of 

 both fresh substance and dry matter, the earlier planting produced the 

 best. There is no doubt but that dropping the seeds in their permanent 

 places is the easiest way of planting when transplanting machines are not 

 used. It may be, however, that by this method more care and work are 

 required in thinning and cultivating. Nevertheless, it is important that 

 the plants have a long growing period and that they receive no check in 

 growth. As to the varieties, all were good. Volga leads in the propor- 

 tion of head to total plant, and it kept better than Surehead or Autumn 

 King. Autumn King seemed to be better suited to clay loam soil than 

 to gravel loam. Surehead did better than Autumn King in 1904 on 

 gravel loam. Danish Ballhead is the lowest in yield, but has compact 

 head, see fig. 14. 



Essentials of a High Yield. 



First, rotation. It matters little what crops be grown, provided they 

 are in accordance with rational practice, the main point being that when 

 cabbage crops follow each other in succession the soil is likely to 

 become infested with the club root fungus which will render it unfit for
