io6 Report of the Botanist of the 



Table VI. — Yield of Cabbage as Affected by Removal of Lower Leaves. 



In every instance, save one, the check row gave a larger num- 

 ber of marketable heads than did the adjacent row from which 

 the leaves had been removed. The average weight of the heads 

 was also greater. The difference in total yield was 1151 pounds, 

 which is at the rate of three tons per acre. Expressed in terms of 

 percentage the reduction in yield due to the removal of ten leaves 

 from each plant was 42.8 per ct.
