WHEAT, OATS, AND BARLEY IN SOUTH DAKOTA. 37 
of the variety may be maintained. The work involved is not great 
and could be carried out on a sufficient number of farms in the State 
to maintain a supply of home-grown seed of good quality. 
Whether the seed plat is used or not, all seed grain should be 
thoroughly fanned to remove all light, inferior seed grain, weed 
seeds, and trash. If the seed is thus kept well graded, the so-called 
running out of the variety will be avoided. 
SUMMARY. 
The small-grain crops, wheat, barley, and oats, have been and still 
are one of the chief sources of wealth in South Dakota. 
The production of wheat has not increased, while that of oats and 
barley has doubled during the decade from 1903 to 1912. There is 
usually sufficient moisture to produce these crops, though the fre- 
quent periods of high evaporation do considerable damage, particu- 
larly in the central and western portions of the State. 
The soils of South Dakota east of the Missouri River are for the 
most part well suited to cereal production; those west of that river 
are extremely variable, though some are of value for grain growing. 
In a climate like that of South Dakota it is very important to 
have adapted varieties. As a result of the investigations reported in 
this bulletin it is now possible to recommend such varieties of wheat, 
oats, and barley for the State. The following varieties are recom- 
mended : 
(1) Wheat. 
Kubanka durum (C. I. No. 1440), Haynes Bluestem (Minn. No. 169), 
Red Fife (C. I. No. 3081), and Fife (Minn. No. 163). 
(2) Oats. 
Swedish Select (C. I. No. 134) and Sixty-Day (C. I. No. 165). 
(3) Barley. 
(a) For the eastern district: 
Manchuria (Minn. No. 105) and Odessa (C. I. No. 182). 
(&) For the central district: 
Hannchen (C, I. No. 531). 
(c) For the western district: 
Gatami (C. I. No. 575), Mariout (C. I. No. 261), and re- 
lated varieties. 
To obtain the fullest return from the use of these varieties, the 
seed must be kept pure and up to a high standard of quality.
