a Yields from acre plats. 6 Average for six years only, 1910 to 1915. 



As stated previously, the yields in 1909 were lowered on account 

 of winterkilling. The average survival on the winter-wheat plats 

 in the spring of 1909 was 41 per cent. Wheat that was sown early 

 did not suffer from winterkilling and yielded from 45 to 50 bushels 

 per acre. 



In 1910 and 1911 the seasonal precipitation was below the average, 

 but as there was no hot weather and most of the seasonal rainfall 

 came in May and June, good yields were obtained. 



In 1912 the rainfall in May was above normal, while the precipita- 

 tion for June was nearly 3 inches below normal. As a result the 

 winter- wheat varieties headed early. A local hailstorm on July 11, 

 when the wheat was fully headed, reduced the yields about 50 per 

 cent. 



In 1913 conditions were about normal and an average crop was pro- 

 duced. In 1914 there was abnormally heavy rainfall in May and 

 June, followed by unusually hot, dry weather in July. This caused 

 the wheat to ripen early. The yields were the lowest recorded at the 

 station, with the exception of those produced in 1912, and the quality 

 of grain was poor. 



In 1915 the temperature during the growing season was below 

 normal, while the rainfall was more than 2 inches above normal.
