Bulletin 264. 



late seeding, and to drought. The greatest differences were due to the 

 lime treatment, which gave an increase over no treatment of over fifty 

 per cent, based on an average of all the check plots. The manure treat- 

 ment was not so effective as in the other work cited in this bulletin. 

 The dry year was probably responsible for the small effect. 



Throughout the whole of the series of plots the chief plants found in 

 connection with the clover were sorrel, daisies and red-top. The propor- 

 tion of each of these was determined by the different treatments. The 

 product could not be rated as clover hay, but rather as grass hay with 

 varying amounts of clover. Although the separation was not made 

 in the medium and alsike plots, the percentage of clover to other 

 plants was higher than in the mammoth plots. The following table, 

 which is based on dry matter and reduced to percentages, gives a com- 

 parison of the relative amounts of the separate crops in each plot. 



It will also be noted that in both experiments the alsike and the 

 medium red clover outyielded the mammoth variety, which is in sharp 

 contrast with the oft-repeated assertion that the mammoth variety 

 is better than small red. The more hardy nature of alsike clover is 

 commonly recognized and many farmers secure crops of it when they are 

 unable to grow red clover. If red cloVer succeeds it is usually preferred. 



Another series of plots in cooperation with Mr. Tupper was tried 

 on this same type of soil, but in a field where the soil was in a more 

 exhausted condition. In this case barley was used as a nurse crop. 

 The experiment was a complete failure so far as the production of clover 

 was concerned. The greatest yield that was produced was less than 

 one-half ounce of dry clover per square rod. This failure cannot be 

 attributed entirely to the soil, as the seeding followed sod and was late, 

 factors which, coupled with a very dry season, could hardly be expected 

 to result in a fair crop.
