 data might be taken for seed onions, but severe infection by onio« m.ld.w

 ehtlsetts Experiment Station, however, as shown in Table 4, increase in 

 e d of seed onions was obtained with increase in lime up to two tons per

 Onions that received lime .howed darker green color, and J - bu.h^

 mndew infection which occurred before the onions made very large 



'"'' E";^;eriments were also conducted at Sunderland and North Hadley in 

 the s^^ter of 1926 in an effort to get further data on the value of lime 

 for d ooion. Both of the fields selected for the experiment had grown 

 onions for several years. Results in both of Uiese ^^^^^r^T^^^ 

 the farm of Arthur Httbbard and W. F. Ryan, are included m Table 4.
