Experiments in the Growth of Clover. 353 



[50 pounds Muriate of Potash, 



Plot 8 Complete fertilizer, •< 100 pounds Nitrate of Soda, 



(100 pounds of Acid Phosphate. 

 " 9 Fifteen tons of manure. 

 " 1 1 Fifteen tons of manure (red clover) . 

 " 12 Fifteen tons of manure (alsike clover) . 



Half of each plot was limed at therateof i5oopounds peracre. Astrip 

 through the center, including half of the limed and half of the unlimed 

 part was inoculated for peas and for clover with soil from successful 

 fields of these crops. All except plots 11 and 12 were seeded with 

 mammoth clover. All plots were seeded at the rate of 15 pounds per 

 acre. Soon after the young plants were up there was a noticeable dif- 

 ference in the size and vigor of both peas and clover on the limed and 

 the unlimed areas. All plots passed the winter in fairly good condition, 

 and in the spring showed practically the differences just mentioned, with 

 the addition that very soon there was a noticeable difference in the 

 plants other than clover growing on the limed and the unlimed areas. 

 On the unlimed plots the principal grass growing with the clover was 

 red-top, which formed a considerable part of the growth on all plots. 

 On the limed plots the red-top was replaced by timothy, which grew 

 well and formed splendid heads. No grass seed was sown. 



During the early part of the summer plot 12, which was seeded to 

 alsike clover, was apparently better than any of the others. The plot 

 seeded to medium red clover was also better than those seeded to mam- 

 moth, but no appreciable differences could be noted in the fertilizer 

 treatments. Plot 9, which had received manure, appeared better than 

 any of those receiving fertilizers. 



These plots were harvested the second week in July, and the hay 

 weighed in a partly cured condition while in windrows. The alsike 

 clover was much more advanced in maturity than the mammoth, while 

 the red was intermediate in ripening. Both the red and the alsike had 

 produced a heavy growth and were lodged to such an extent that a large 

 amount was left as stubble, so that the yield, when compared with the 

 mammoth clover, was greater than is indicated in the table of yields. 



The inoculation produced no noticeable results in any case, either on 

 the peas or the clover.
