Oats were selected as the crop suitable to serve for that 

 purpose. The general management of the experiment, as

 down are concerned, was the same as in preceding years, as 

 will be seen from the subsequent description of the operation. 



The field was ploughed Sept. 22, 1892 ; during the suc- 

 ceeding March the barn-yard manure was applied broadcast 

 to Plat 0, and April 29 the entire field was again ploughed. 

 The remaining plats, 1-10, received their different fertilizer 

 mixtures broadcast on May 4. The entire field was harrowed 

 and pulverized a few days later. The oats were sown May

 and two-thirds pounds per plat. The seed when tested by 

 germination showed eighty-two per cent, of live seed. The 

 young plants appeared above ground May 22. June 2 and 

 again June 17 all plats were cultivated and hoed.
