Coutinuous Rye. No nitrogen supplied. 



Continuous Eye. Nitrogen supplied by leguminous crop grown each year 

 after harvesting the Rye. 



The above illustrations are from a report of the New Jersey Agricultural College 

 Experiment Station. Similar restilts were obtained with wheat. _ The yield of rye 

 grain was nearly one-fourth greater, and the yield of wheat grain was more than 

 double on the plots where legumes were grown. The experiment clearly shows that 

 by growing legumes it is possible to increase the yield of succeeding non-legume crops, 

 both in grain and in straw, and therefore in the amount of nitrogen accumulated.
