Coniparlnj;- velvet bean vines with velvet bean stubble 

 the difierence in favor of the vines was 452 pounds 

 of seed cotton per acre in the first crop. 



Corn in 1900 on this plot yielded 14 per cent., or 2.6 

 bushels per acre more than did corn on the nearest plot 

 where in 1898 cotton instead of velvet beans had 

 i;rown. As the stubble plot was slightly lower down on 

 the hillside we suspect that the increase was partly due 

 to this disturbin*;- condition and not wholly to the re- 

 sidual effects of the velvet bean stubble of 1898. 



It v>^as on this s.tubble plot that in 1898 the velvet 

 bean liaj' (8,240 pounds per acre) contained 188.7 

 pounds of nitrogen and the roots and stubble and fallen 

 leaves only 12.5 pounds of nitrogen per acre. (See Ala- 

 bania Station Bulletin, Ko. 104, page 330.) 



Immediate Fertilizing Effects of Cowpeas on 



Oats in 1897. 



^'On sandy soil in 1896 several plots were sown broad- 

 cast with tlie Wonderful variety of cowpeas, and an 

 adjacent plot was sown broadcast with German millet. 

 The German millet was plowed under, as were also the 

 peavines, the peas having been previously picked. 



February 18, 1897, Ked Rust Proof oats were sown 

 after the above mentioned crops, using in both cases 

 100 pounds of acid phosphate and SO pounds of nitrate 

 of soda per acre.
