CORF, 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. ^VTien a comparison is made between milo and kafir it is 
seen that milo has given the better yields of grain and that kafir has 
£iven 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.
