KAFIR AT DALHART. 



Kafir has been grown at Dalhart, Tex., for six years. During this 

 time five different methods of seed-bed preparation and cultivation 

 have been under study. Kafir after small grain on fall-plowed land 

 was discontinued in 1914, on account of the impracticability of grow- 

 ing small grain. The results obtained during this study have on 

 the whole been very satisfactory. The yields, and consequently the 

 profits, obtained here are higher than at the other stations under 

 study. There is also a wider range in the results obtained with the 

 different cultural methods used, which would indicate that cultiva- 

 tion here is of more importance than at Garden City, Kans., or at 

 Amarillo, Tex. The largest average net profit obtained was from 

 the crop grown on land summer tilled the preceding year, amounting 

 to $20.11 per acre. The method showing the least profit is that of 

 fall plowing following small grain. The profit by this method was 

 only $2.90, which is considerably below the average of the other 

 methods used. 



It is possible that the low profits shown by this method are due 

 to the difficulty of securing a stand and to the fact that the small 

 grains leave the soil very dry. Listing after kafir has given a net 

 yield of $12.04 per acre, which is considerably higher than by any 

 other method except summer tillage. Kafir after kafir on fall- 

 plowed land has given an increased profit of $1.43 per acre over 

 kafir following kafir on spring-plowed land. 



After both listing and summer tillage the value of the grain crop 

 alone has been sufficient to pay the cost of production. Under all 

 methods the value of the forage has exceeded that of the grain.
