Cabbages for Stock-Feeding.

show that some varieties did better when planted shallow, while others 

 did better when planted deeply ; but since the differences were slight and 

 might readily be due to other causes the conclusion arrived at was that 

 the depth at which strong and stocky cabbage plants are set does not 

 influence the extent or weight of the crop (C. U. Report, 1891). 



Thirty-inch rows or even thirty-six inches are preferred on the Uni- 

 versity Farm, because of the greater ease in using machinery. Such 

 widths permit of clean culture and frequent and late intertillage. It is 

 preferred to crowd the plants in the row to 24 inches if necessary, and 

 have wide rows, and fewer to the acre, as by so doing the cost of growing 

 is thought to be reduced. There should be from 7,500 to 9,000 plants 

 per acre and no missing places. 



Rotation. 



Cabbages may be grown in place of corn or other intertilled crop in 

 a short four- or five-course rotation. It would hardly be deemed advis- 

 able to put them on an old sod on account of the trouble from cutworms 

 and wire-worms. 



Varieties and Yields. 



During the three years' trials four varieties have been grown, one of 

 them, however, the Volga, for only two years. In addition to the varie- 

 ties, a trial was also made of two dates for planting. The earlier date 

 was practically the second week in IMay, when the seeds were sown in 

 their permanent places and afterwards thinned. The latter date was 

 practically the third week in June. For these plantings, plants were taken 

 from the earlier sowings. The third year, the late planting was not made. 



The following tables give the yields of fresh and dry substance, with 

 percentage for each variety, during the period of their trial :
