Effect of Fertilizer upon the Composition and Storing Quality of Carrots. 



Carrots were grown with an excess of nitrogen, phosphorus, potash and a 

 combination of these elements. These carrots will be analyzed for their car- 

 bohydrates both before harvesting and during the storing period. 



Timothy Selection. 



In the experiment conducted by F. W. Taylor (Agronomy), to produce an 

 improved strain of timothy, eighteen of the most ideal plants were selected in 

 the testing plot of 1922. Seed from each of these was planted in separate 

 rows in August. In June, 1923, one hundred plants from each of these rows 

 were set out three feet each way in a new testing plot. On account of the 

 extremely dry weather during June and July, about 80 per cent of the young 

 plants died. It will, therefore, be necessary to start the testing anew from 

 the same parent plants next season. 



Of the plots which were put in by county agents in 1921, it was possible to 

 locate and visit but one this season. On this plot, which was hardly fairly 

 located (being near the top of a slope with the other plots below where there 

 was more moisture), the timothy was earlier and leafier, but with shorter heads 

 and not so tall as on the plots seeded with the Ohio and commercial strains. 



Variety Tests of Ensilage Com. 



Seven varieties of ensilage corn were planted on one-twentieth acre plots June 

 2. The corn was harvested September 25. It was slight!}' frosted and some- 

 what dry at cutting time, so that the weights were a little lower than they 

 would have been a week earher. The results were as follows:

Soil Fertility. 



The soil fertility plots, started in the. faU of 1920 and outlined in our last 

 report, were all in hay this year. These plots were carefully trimmed out, 

 measured, and the aii'-dry weight of hay determined in the field. The plots 

 varied much, and because of these variations the probable errors were too 

 large to draw definite conclusions as yet regarding fertilizer treatments. In 

 general, all plots showed a good increase in yield from plowing, liming and 

 reseeding over the surrounding territory which had not been so treated. The 

 plots varied in yield from 2495 pounds to 4866 pounds of air-dry hay computed 

 to an acre basis. 



The second set of duplicate plots, started in 1921 and virtuallj' abandoned 

 during the wet season of 1922, have this year been carried on practicallj^ in
