At each of these substations plats 10 feet square for each variety of seed used 

 were prepared by plowing or spading to a depth of 10 iuclics. 



Notes and tabulated data ou the time of plautiug, the weather during 

 the season of growth, and the average results in weight and sugar 

 content of beets at each substation are given for each of the three 

 districts. The average results from the different districts were as fol- 

 lows:

* The number of heat units in a month is the product of the daily average of temperature by the 

 number of days in the month. 



The sum of the heat units during an average year in this State differs but little 

 from the sum of the heat units required in Europe for sugar production, notwith- 

 standing the fact that the months of June, July, and August are much warmer with 

 us than there. 



As a compensation for this excess of heat for these months we have a greater rain- 

 fall during these mouths than does the beet-growing region of Europe, as will be seen 

 from the rain chart of Nebr-aska and Central Europe [given in the bulletin]. 



Beet seed was distributed through the county agricultural societies 

 and directly by the station to some 2,000 farmers throughout the State. 

 Nearly 500 samples of beets were sent in to the station for analysis, 

 together with reports on the conditions under which they were raised. 

 These reports and the results of the analyses are summarized in tables, 

 which fill 28 pages. The data include the name and address of the
