350 ELEMENTS OF CROPS. 



yield 48 lbs. of hay. The relation of green to dry fodder varies 

 with the age of the plant, and the meteorological circumstances 

 under which it has grown. Subjoined is the result of some experi- 

 ments which I performed on the making of clover hay : 



1 ton of clover in flower, 2d year (1841) afforded in hay 7 cwts. 



1 ton of clover 1st year (1842) " 4 cwts. 2 qrs. 24 lbs. 



The average produce of this fodder reduced to hay at Bechel- 

 bronn is 41 cwts. 3 qrs. per acre. 



One of clover hay, after complete desiccation, weighed 0.790 ; 



one of dry hay left 0.078 of ash :

TURNIPS. 



When turnips are cultivated as a second crop, as after rye or 

 wheat, the produce is very uncertain. Attempts are occasionally 

 made to raise them after wheat which has followed clover. 



When cultivated on fresh manured soil, the produce is considera- 

 ble ; in some places it amounts to from 28 to 33 tons per acre ; but 

 as a second crop, we only obtain upon an average 7| tons per acre. 

 This crop is only counted as a half-crop in the general produce of 

 the rotation. 



Turnip is the most watery root I have examined. A slice weigh- 

 ing 2 oz. 17 dwts. dried in the stove, was reduced to 4 dwts. After 

 thorough desiccation, one of turnip weighed 0.075 ; consequently 

 the root contains 92.5 per cent, of water ; one of dried turnip incin- 

 erated, left 0.0758 of ash :

OATS. 



As this grain closes the rotation, the produce is not great. The 

 average crop is 37 bushels per acre, at the weight of 33^ lbs. per 

 bushel ;* one of oats conrpletely dried weighs 0.792 ; one of dried 

 •ats leaves 0.0398 of ash ;
