REPORT OF SEED IMPROVEMENT WORK.

No. 4 aiid row No. i was 12,792 lbs., or a little over six tons 

 per acre. The results given in these data are much more uni- 

 form than those found in the records of the majority of experi- 

 mental plots. 



Following is a summary of the results of another experimental 

 plot, showing greater variation in yields per acre.

In those data a record is given of the germination test of the 

 ten mother ears used in planting the experimental plot. Al- 

 though each of the ears germinated ioo%, it will be seen that 

 some of them germinated quicker than others. Row No. i 

 germinated ioo% in 96 hours, while row No. 7 and row No. 10 

 required 192 hours. One of the interesting things noticeable 

 in this record is the relation of the total yield of corn to that 

 of seed corn. There was not as much variation in the total 

 yield of corn per acre as in the yield of seed corn. In row 

 No. I, with a total yield of 127 bu. per acre, 82 bu. were fit 

 for seed; in row No. 10, with a total yield the same as No. i, 

 only 7 bu. were fit for seed purposes. As each row was planted 

 with an individual ear of corn and the ten ears used in plant- 

 ing the plot were carefully selected for uniformity, the diflfer- 

 ence in the ability of individual ears to reproduce is made very 

 evident by the above data. 



EXHIBIT AT THE NEW ENGLAND CORN EXPOSITION. 



In accordance with an invitation extended by the New Eng- 

 land Corn Exposition, the Maine Seed Improvement Associa- 

 tion made an exhibit at the Exposition in Worcester, Mass. 

 Upon a request made to the members, 220 exhibits of corn, grain 

 and potatoes were received at Augusta and transported to Wor- 

 cester and exhibited by the Maine Department of Agriculture. 

 The Maine Agricultural Experiment Station contributed an ex- 

 hibit of 31 varieties of oats with which they are doing experi- 

 mental work for the benefit of the Maine Seed Improvement As-
