WORK OF TRUCKEE-CARSON EXPERIMENT FARM IN 1912.

29, and a high wind on June 20 resulted in some injury to the sugar- 

 beet crop. The disease known as curly-top, which destroyed a large 

 area of sugar beets in 1911, was absent in 1912, and the yield was good, 

 although the acreage was much smaller than in 1911. The damage 

 to the potato crop by the nematode gallworm was much less exten- 

 sive than it was the previous year. 



The total irrigable area of the 497 farms on the project in 1912 was 

 54,937 acres, of which an area of 36,620 acres was actually irrigated. 

 The acreage, yields, and farm values of the crops grown in 1912 are 

 stated in Table 11. The figures were obtained from the United States 

 Reclamation Service.

FIELD-CROP EXPERIMENTS. 



On account of the great lack of uniformity in the soil of the ex- 

 periment farm and the presence of harmful quantities of alkali salts, 

 the field-crop experiments have not been extensive. Until the ex- 

 periments Avhich are being conducted with a view to removing the 

 alkali salts from the soil are successfully applied to the entrie farm, 

 the crop experiments will be much limited, both in number and in 

 land area used. There is given below a brief account of the more 

 important field-crop tests conducted in 1912. 



SUGAR BEETS. 



A fertilizer test Avith sugar beets was conducted on a clay soil which 

 had not previou.sly grown a cultivated crop. The soil was not uni-
