BENEFICIAL EFFECT OF CLOVFIJ

wheat from .5240 lb. to .">(3i:} lb., or by 7 per (ciii. On ihr 

 completely mamired plot a still greater erop u[' clover is 

 obtained, averaging r>3 cwt., and this still further iiicrea.ses the 

 wheat crop from 'A79 lb. to OIHO lb., or by \'2 per cent. 



With the beans an entirely different result appears; on 

 each of the three plots the bare fallow pi-oves a better prepira- 

 tion for wheat than does the bean croj), after which in all cases 

 the wheat crop is scmiewhat dinn'nished. On the nnniaiune.l 

 plot the average diminnticm is 11 i)er cent., on the mineral 

 manm-edj^lot it is I'o per cent., and on the completely manured 

 plot it is 27 per cent. In other words, the bean crop, which is 

 pulled, not cut, does not leave behind any great amount ol' 

 nitrogen gathered from the atmosphere — not sufficient to 

 compensate for the absence of the summer tillage that the 

 bare fallow receives. These results are even more clearly seen 

 Avhen the crops following the largest clover and bean crops 

 are considered, the results of which are set out in Table 

 LXVIII.

In 1894 the clover on the unmanured jilot produce<l only 

 16-5 cwt. of hay and caused a barely perceptible increase in the 

 total produce of the wheat, amounting to only 2 per cent. On 

 the plot receiving a complete mineral manure, however, a very 

 large crop of clover was obtained, r)97 cwt. per acre, and this 

 increased the total produce of the wheat crop from 4220 lb. to 

 5180 lb., or by 227 per cent., the extra grain anmunting to
