be tested, the use of a " standard type" is absolutely necessary; 

 in case of only a few varieties (4 to 6), the standard type may 

 be omitted, and instead the test rows of the others should be 

 repeated once or twice more making 4 or 5 series of plantings, 

 instead of only 3. 



6th: The size of the test fields greatly depends upon the 

 degree of accuracy of results which are expected from the tests. 

 For an accurate determination of the sugar content an area of 

 approximately 120 to 150 square yards is sufficient. For the 

 yield test, at least three times that area is necessary, viz: ap- 

 proximately 450 square yards. When planning the size of the 

 test field due consideration must be given to the labor at your 

 command, as all the work in connection with the test field 

 throughout the season should always, if at all possible, be per- 

 formed in one day. 



7th: As to the shape of the test field, same is dependent 

 on soil conditions and slope; generally speaking an oblong 

 parallelogram is most desirable, as it brings the different vari- 

 eties in close proximity, thus making their growing conditions 

 as nearly alike as possible. Each test plot, if one may thus 

 designate each seeding of a variety, must consist of not less 

 than three rows, and better five, the latter number increasing 

 the accuracy of the results. For the determination of the sugar 

 and yield of each variety only the one center row is used, in 

 case of three row plots, and the three center rows are used in 

 case of 5 row plots. The advantage of 5 row plots needs no 

 further comment. 



8th: The seeding and all other cultural labor should be 

 performed in the same manner as is practiced in the open field, 

 but the utmost care should be exercised to do all the work well 

 and accurately. Where the seeding is done by hand instead of 

 a Planet Junior hand seeder, uniform dropping of the kernels 

 is absolutely necessary, and just as important is a most accurate 

 spacing and thinning at a uniform distance throughout the test 

 field. All varieties must be thinned at the same distance, and 

 the width between rows must be likewise the same throughout 

 the field. At the time of harvesting all beets must be uniformly 

 topped and cleaned and the roots must not be broken off by
