5056 pounds of hay to an acre, and in the second season 

 three cuttings gave 6320 pounds to an acre. On another 

 plot the results were respectively 6672 and 7048 pounds 

 to an acre. 



At the Massachusetts Experiment Station, a plot 

 seeded May 8 yielded September 9 at the rate of 2700 

 pounds of hay an acre. The next season it was cut on 

 June 24 and September 22, yielding respectively 2727 and 

 1000 pounds an acre. 



At the Utah Experiment Station a yield of 7700 pounds 

 of hay an acre was obtained. At the Wyoming Experiment 

 Station yields of 8960 pounds and 7500 pounds of hay to 

 an acre were secured. At the Ontario Experimental Farm 

 a yield of 61,300 pounds green matter an acre is recorded. 



508. Seed-production. Seed of sweet clover is pro- 

 duced both in Europe and in the United States. Euro- 

 pean commercial seed is always hulled. American seed 

 is always in the hull and is produced in the South and in 

 Kansas. On account of the limited demand until now the 

 methods of seed-production have not been especially 

 developed. The best yields of seed come from thin 

 stands that have not been cut for hay, but satisfactory 

 yields may be obtained from fields that have previously 

 produced one cutting, or in the South two cuttings of 

 hay. To avoid shattering the hard stems should be cut 

 when damp, and cured in small shocks ; or it may be cut 

 with a binder. The time to cut is when about thr*ee- 

 fourths of the pods have turned dark. In western Kan- 

 sas it is sometimes harvested with a header and cured 

 in medium-sized shocks. In the South the seed pods 

 are usually removed by nailing, but in the West grain 

 thrashers are now used. The yields in Kansas ar.e said 

 to be from 2 to 8 bushels to an acre.
