EXPERIMENT STATION, 



[Jan. 



Lime Experiment. 



An experiment to study the relative value of different sources 

 of lime on the basis of equal applications of combined calcium 

 and magnesium oxides was begun in 1914. The field selected 

 for this experiment is the one on which for so many years we 

 studied the effects of spring and winter applications of manure. 

 The plots have received no manure or fertilizer since 1911. 



The crop this year was medium green soy beans grown for 

 seed. The crop was harvested October 18 and 19, and threshed 

 in November. The following table gives the yields per acre on 

 the different plots : —

Variety Test Potatoes. 



This year we have had 21 different varieties of potatoes in 

 our variety test work. The varieties planted this year were 

 selected from the more promising varieties grown last year. 

 This seed originally came from widely different sources; the 

 present season is the fourth that these varieties have been 

 grown on our plots. The plan included two rows of each variety 

 with every seventh row as a check. The Green Mountain 

 variety was planted in the check rows. 



The following table shows the variety and yield obtained this 

 year. Those with one star ranked among the five best yielders 

 in one of the preceding years; with two stars, ranked among 

 the five best yielders two of the preceding years; and with 

 three stars, ranked among the five best yielders all three of the 

 preceding years.
