tion of barnyard manure at the rate of 15 tons per acre. 

 Every season, the field was disked from three to four 

 times and harrowed. During 1903 and 1904, web worms 

 damaged the crop. 



Yields of Plats i, 2, 3, and 4, Field E. The plats are 

 on similar soil to that of Field F g,nd have been handled 

 about the same as that held. The yield is given for all 

 the plats together. 



1902-2.67 tons hay per acre. 



1903-3.27 tons hay per acre. 



1904-3.3 1 tons hay per acre. 



Average for three years, 3.08 tons of hay per acre. 



Yield of Field H, containing about five acres: 



1902-4.20 tons hay per acre in 5 cuttings. 



1903-2.88 tons hay per acre in 5 cuttings. 



1904-2. 12 tons hay per acre in 5 cuttings. 



1905-2.27 tons hay per acre in 5 cuttings. 



Average for four years 2.69 tons per acre. 



Barnyard manure was applied to this field in i900-'oi, 

 and it was given the same treatment as was received by 

 the fields previously mentioned. Other results will be 

 given in a later bulletin, but those cited give a fair idea 

 of what may be expected on upland where the subsoil 

 is a hardpan. The hay from all the fields mentioned 

 above, obtained in the last two or three cuttings, con- 

 tained varying amounts of crab grass, so the yields given 

 are not all alfalfa. Since the above results were obtained, 

 some good bottom land has been acquired by the experi- 

 ment station and alfalfa has already been seeded on some 

 of it. In a few years, yields that will look better when 

 compared with those of our best alfalfa growers can
