74 Report of Progress in Tobacco Investigations. Jones, J. P. 8 p. 

 April 1927. 



The results obtained during the first three years of an experiment comparing dif- 

 ferent cropping systems for tobacco are presented. Tobacco grown in rotation with 

 (1) corn and hay, (2) potatoes and onions, (3) corn, (4) hay, (5) potatoes, and 

 (6) onions, was compared with tobacco grown every year on the same land (1) 

 with fertilizer only, (2) with fertilizer and manure, and (3) with fertiliiier and 

 timothy cover crop. Tobacco grown in continuous culture proved tetter than that 

 grown in any other cropping system ; tobacco receiving manure and fertilizer better 

 than that with fertilizer only ; tobacco without a cover cj-op much better than that 

 with a cover crop, or that grown in any of the rotations except with onions.
