CORN, MILO, AND KAFIR IN" THE GREAT PLAINS AREA. 19 



Experimental work was started one year earlier at Amarillo than 

 at the other stations. Aside from this it has been carried on during 

 the same years at each of the stations. 



Summer tillage for milo and kafir has only recently been put under 

 trial at Garden City. With this exception the same cultural methods 

 have been used at each place. Small grains in this area have given 

 generally unsatisfactory returns, although they have been much bet- 

 ter at Amarillo than at either of the other two stations. 



Saccharine sorghums have proved well adapted to conditions in 

 the southern Great Plains area and usually have given good yields. 

 The same cultural work has not been done with them as with the 

 other crops. In general they may be expected to show about the 

 same response to cultural conditions as is shown by the grain 

 sorghums, for which results are here reported. 



The results of this work show that corn can be depended upon to 

 produce good crops of feed in this section. It does not, however, 

 produce as big a tonnage of feed as kafir and is not as reliable as 

 either kafir or milo in the production of grain. In trials covering 

 six years at Garden City it has failed to produce a grain crop by 

 any method. At Dalhart it has produced good crops of grain in 

 three of the six years that it has been under trial. At Amarillo it 

 has made but one creditable grain crop in seven years. Because of 

 its comparatively poorer adaptation to conditions, it does not show 

 relatively as great a response to cultural practices as does either kafir 

 or milo. 



Both milo and kafir have given higher average yields than corn at 

 all of the stations. They have also been safer crops, having made 

 crops of grain in some years when corn did not. They have also 

 been more responsive to cultural operations, thus proving their bet- 

 ter adaptation to conditions. On the sandy lands of this area corn 

 makes a better showing in comparison with these crops than it does 

 on the heavy, "tight lands," on which corn has little place in this 

 section. When a comparison is made between milo and kafir it is 

 seen that milo has given the better yields of grain and that kafir has 

 given the better yields of roughage. Kafir, however, has shown a 

 somewhat greater response to methods that, like summer tillage, in- 

 crease the yields. When equal values are assigned to the grain and 

 to the roughage from each of the crops, the total return is generally 

 about the same from each. At Garden City the grain crop alone has 

 not been sufficient to pay for the cost of production. At Dalhart 

 both crops have produced sufficient grain by all methods to pay a 

 profit. At Amarillo milo has returned a profit from the grain alone 

 by some methods. The crop of kafir grain at Amarillo was not suffi- 

 cient by any method to pay the cost of producing the crop.
