Maine Agricultural Experiment Station. 1919. 



in the complete fertilizer plots and in the check and no am- 

 monia plots when grouped by threes (rows I to 3, 4 to 6, and 

 7 to 9) the yields are the largest at the east end and decrease 

 pretty regularly toward the west. 



Although the resulting yields indicate that the field is not 

 as uniform as it was hoped the experiment will be continued 

 for at least another growing season. 



Table showing yields per rozvs of the plots that have complete 

 fertiliser (ammonia, phosphoric acid and potash) and plots 

 that carried no fertiliser or a fertiliser without am- 

 monia. The yields of the potatoes in ipi/ are 

 given in hundredweights and of oats in 1918 

 in bushels per acre.
