502 Bulletin 280. 



PLOT 15 



4 lbs. Kentucky blue-grass 2 lbs. meadow foxtail 



4 lbs. red-top 2 lbs. perennial rye 



4 lbs. timothy i lb. hard fescue 



2 lbs. meadow fescue 4 lbs. alsike clover 



2 lbs. smooth brome 3 lbs. red clover 



2 lbs. orchard grass 2 lbs. alfalfa 



2 lbs. white clover 



At the end of the first year the principal plants found in this plot 

 were red-top, timothy, red clover and Kentucky blue-grass. None of 

 the other grasses or clovers occupied a prominent place. Later meadow 

 foxtail and white clover became important and these two plants have 

 persisted along with Kentucky blue-grass. The other grasses and clovers 

 have practically disappeared. 



The soil is poor in this part of the field. It is not adapted to either 

 orchard-grass or meadow fescue. 



GENERAL FEATURES OF THE GRASS PLOTS 



It will be seen from the foregoing discussion that timothy and red- 

 top became prominent at an early date when sown in mixtures with 

 the other ordinary pasture grasses and clovers. Meadow fescue, orchard- 

 grass and brome-grass do not appear to be able to compete with these 

 two grasses on this type of soil. Tall oat-grass and meadow foxtail 

 scarcely appeared during the first year. Perennial rye has not been 

 observed at all during the progress of the experiment. 



Timothy and white clover have appeared in every plot even though 

 they were not included in the seeding. The amount of these, however, 

 has not been great except where the seeds were sown. 



Canadian blue-grass was not included in the seeding of any plot, 

 yet it is now present in patches all over the field. It has not encroached 

 seriously where Kentucky blue-grass was sown, but it is very prominent 

 in some of the other plots. It was first observed in 1907 on plot 3, which 

 had received nothing but meadow fescue. 



Meadow fescue has all but disappeared where sown alone. There is 

 still a small amount on the plots where it was used in mixture. 



Red-top is not prominent in any plot, except in parts of plot 2 which 

 received 20 lbs. of this per acre. It is generally true that it is not
