100 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



Work was actively pursued during the past j^ear on seven Adams 

 fund projects. Studies on the ghiten content of wheat were con- 

 tinued sj'stematically along the same lines as reported last year. At 

 Gooding, where a part of the work is carried on, studies were made 

 of the effect of irrigation and methods of culture on the nitrogen 

 in the soil and on the composition of wheat. In this connection 

 three varieties of wheat were each grown on seven plats receiving 

 different amounts of water. At Moscow the effects of fertilizer and 

 rotation were studied in a similar way with different varieties of 

 wheat, including some from Minnesota, Kansas, and Nebraska. A 

 large amount of chemical work on wheat and wheat flour was done 

 during the past year and baking and milling tests were brought to 

 a conclusion. 



The cooperative studies with this office on the duty of water in irri- 

 gation were continued at Gooding. The field experiments consisted 

 of the application of different amounts of water at different times 

 and by different methods in growing a number of field and garden 

 crops. Evaporation experiments were conducted to strengthen the 

 data secured in the field work. 



The apple-breeding investigations included making 5,802 pollina- 

 tions and placing 2,901 bags on trees. As a result of this work, 702 

 apples set, which gave an average of four seeds apiece. The question 

 of self-sterility was studied, and 180 hybrids were grown from seed 

 secured in 1910. 



The bacteriological study of butter in relation to keeping was con- 

 tinued as originally outlined. In connection with the work on the 

 effect of different factors on the bacterial flora of the product, about 

 150 different organisms have been identified. A large amount of 

 data has been accumulated. 



A study of the duty of water in plant growth was carried on b}'^ the 

 agronomist under controlled conditions with some of the more im- 

 portant field crops. The plants were grown very successfully, and 

 detailed records regarding their development were carefully kept. 

 The agronomist also continued his work on the relation of calcium 

 and magnesium in the growth of wheat. 



Bacteriological studies of soil were conducted at the station and 

 partly in connection with the duty of water studies at Gooding. 

 Some work was also done with Azotobacter in soils of different 

 regions. 



With Hatch and other funds the agronomist conducted fertilizer 

 experiments with wheat, oats, and corn: rotation experiments in 

 eight series for the purpose of determining a system to do away with 

 summer fallowing; made ear-to-row tests of corn; and compan^d 

 varieties of wheat, barley, oats, corn, potatoes, peas, soy beans, sor- 

 ghums, etc.
