CORN AT DALHART. 



Six crops of corn have been grown at the Dalhart station. In three 

 of the years under study grain was produced, while in the other three 

 years nothing but stover was produced. The best yield was obtained 

 in 1914, when optimum seasonal conditions for the production of this 

 crop prevailed. Listing has been productive of the highest average 

 yield of grain, but it is thought that this may be due to the fact that 

 the listed plat occupies such a position on the farm that it sometimes 

 receives considerable run-on 7 . Because of the low cost of this method 

 of preparation it gives the greatest profit. Summer tillage is the 

 most costly method of seed-bed preparation : consequently it returns 

 rather a low profit, although it insures a good yield of fodder every 

 year. The difference between the average yields by spring and fall 

 plowing is very slight.

COKN AT AMA1ULLO. 



Seven crops of corn have been grown at Amarillo, Tex., and. 

 although only one complete grain failure is recorded, the yields of 

 four years were so low that husking would have been impracticable 

 in farm practice. The 1008 yields varied from 11.7 to 27.6 bushels 

 per acre. If such yields could be obtained consistently, the growing 

 of corn in this section would be justified. The average yields, how- 

 ever, are not sufficient to cover the cost of production. All methods
