for the purpose of establishing a series of plot experiments with 

 fertilizers at Aroostook Farm. Raw phosphates will be used 

 on some of these plots. 



Commercial Varieties oe Oats at Aroostook Farm in 1915. 



A preliminary test of different varieties of oats was carried 

 out on Aroostook Farm in 1914. For several reasons the results 

 obtained in 1914 were not entirely satisfactory. The farm was 

 purchased very late in the fall of 1913 and there was little 

 opportunity to learn anything by observation of the land until 

 planting time was come. Because of everything being new to 

 the staff it was impossible to get the oats planted as early as 

 they should have been. The very loose character of the soil 

 allowed the heavy disk drill used in seeding to put the seed too 

 deeply in the ground. All of these things tended to lower th? 

 yields. 



In 191 5 the work at the Farm was very much better organized 

 and more favorable results were obtained. Fifteen different 

 varieties were grown each in a single half acre plot. These 

 varieties were all sown with a large disk drill. In order to pre- 

 vent the seed going into the ground too deep the land was 

 rolled before drilling. The seeding was at the rate of 3 bushels 

 per acre. 



The yields for the year are given in the table that follows.
