MICHIGAN EXPERIMENT STATION BULLETINS. 



199 



To test the comparative productiveness of some of the leading varieties, 

 a row, twenty rods long, of each sort, was planted in the spring of 1891. 

 The previous fall a row of Bubach, Haverland, and Pearl had been set out 

 for comparison with spring-set plants. The fall-set plants make np the 

 row first given in the table below. The plat was well manured before the 

 plants were set out and given good cultivation afterward. When the 

 ground was frozen the plants were covered with marsh hay. In the spring 

 the covering was removed from the plants and allowed to remain in the 

 rows as a mulch. 



The following table gives the crop obtained : 



• Fall set plants. 



The following diagram shows at a glance the earliness and productive- 

 ness of the varieties in the preceding table:
