1914, and 1915. The hard red spring wheat, Converse, outyielded 
both of the durum varieties in 1911, 1918, 1919, and 1922. In 1920 
it outyielded Arnautka and practically equaled Peliss. With the 
exception of 1920 these were all droughty seasons.

Since 1917 the wheat varieties have been grown in duplicate plats 
on fallow and on cornland. The average yields of the most important 
varieties on each soil preparation 3 
are shown graphically in Figure 17. 
Winter wheat on both fallow and 
cornland has outyielded spring 
wheat. All of the varieties of winter 
and spring wheat, except Kanred 
winter wheat, have yielded about

From the results obtained it is intheave years, 1917-1922, mdlusive ns 
evident that winter wheat yields 
higher than spring wheat almost every year. The winter-wheat 
crop may be injured by soil blowing and winterkilling, but with a fair 
stand of plants winter wheat will outyield spring wheat in an average 
season. The advantage of the best winter wheat over the highest 
yielding spring wheat, Peliss durum, as shown in Table 20, is 2.4 
bushels for the 14-year period. In the 5-year period, 1917, 1918, 
and 1920 to 1922, Kanred winter wheat has outyielded Peliss spring 
wheat by nearly 10 bushels to the acre when both were grown on 
fallow and by 11 bushels when grown on cornland.
