SUMMARY FOR THE YEARS 1906, 1907 AND 1908. 



It has already been said that one must not place too much 

 emphasis on one year's results. They represent a comparative test 

 of a number of varieties under an existing set of seasonal condi- 

 tions. With other seasonal conditions we might expect to find 

 other varieties with different adaptabilities doing best and giving 

 the largest yields. This has been true in some cases in this co- 

 operative work in the variety tests of corn. For this reason we 

 here add a summary of the variety tests for the years 1906, 1907 

 and 1908. 



In comparing the yields of the various varieties for the past 

 three years we find, in general, the same varieties giving the larg- 

 est yields and the same ones giving the smaller yields as in the 

 test for the year 1908 alone. There are some marked exceptions 

 to this, however. In noting the place in which Reid's Yellow Dent 

 stands, in the average for the whole of the three years, we find 

 it to be below Learning, St. Charles White and Legal Tender, 

 while for 1908 alone it stood third in yield. This is, of course, a 

 very great difference and shows that while the Reid's Yellow Dent 

 v^^as well adapted to North Missouri under the conditions existing 

 the last year, in a number of years so high a yield could not be 

 expected. While this variety seems not to be particularly high 

 yielding in an average number of years, yet we note, in the table 

 giving the number of men preferring the different varieties, that 

 it stands next to the top, showing that it has very good character- 

 istics, which makes it desirable, perhaps, aside from yield; the 

 actual yield of bushels per acre, however, is of course the mosl. 

 important factor. One other variety which is worthy of note is th^ 

 Legal Tender, which in the average for the past three years stands 

 fourth in order, while in 1908 it stood ninth. 



Comparing the yields of North Missouri for the past three 

 years with that of the last season we find Commercial White, 

 Boone County White and St, Charles White at the head of the list 

 in both cases. St. Charles Yellow, which gave very satisfactory 

 yields in the year 1908, it will be observed gave very unsatisfactory 

 yields averaging the three years. This is probably the greatest 

 difference to be noted in North Missouri. 



In South Missouri again we find Commercial White and 

 Boone County White at the head of the list in both cases ; also 

 Hildreth's Yellow Dent stands up well for the average of the last 

 three years as well as the past season. One very marked excep-
