638 EXPERIMENT STATION RECOED. [Vol.35 



and per 1,000 kernels, but the average percentage of grain as based on the total 

 yield of grain and straw was higher with the winter wheat varieties. 



The test of varieties of winter rye showed Lochow Petkus as the leading sort, 

 with Himmel Champagne ranking next, and Sperling Green Kerneled, Krafft 

 Zetland, and Riimker Yellow Kerneled as promising varieties. In a nine-year 

 test Lochow Petkus produced on an average 2,775 kg. of grain and 5,996 kg. of 

 straw per hectare, while Himmel Champagne yielded 2,630 kg. of grain and 

 5,674 kg. of straw, but ranked above the other variety in average percentage of 

 grain, liter weight, and 1,000-kernel weight. 



The leading variety of oats in tests carried on for six, five, and four years 

 was Strube Schlanstedt, followed by Svalof Goldregen and Leutewitz Yellow. 

 In the three and two year tests all these varieties fell below Lochow Yellow 

 and Svalof Siegeshafer. In the six-year test the varieties above mentioned 

 yielded an average of 3,423 kg. of grain and 4,718 kg. of straw per hectare, the 

 proportion of grain to total production being 42.05 per cent, the liter weight 

 513 gm., the 1,000-kernel weight 28.081 gm., and the proportion of hull in the 

 grain 25.09 per cent. 



Varieties of brewing barley were tested for only three years. The average 

 grain production was in favor of Improved Pfalz, yielding 3,821 kg. of grain 

 and 4,804 kg. of straw per hectare. This variety also ranked first in proportion 

 of grain to total yield with 44.45 per cent, in liter weight with 690.5 gm., and 

 in 1,000-kernel weight with 48.39 gm. The average protein content was 11.85 

 per cent which, although rather high, was nevertheless lower than in any other 

 variety. Nolc Bohemia and Heil Frankengerste stood next in value. 



The data secured with varieties of sugar beets indicated in general that a 

 decrease in beet production was associated with an increase in leaf production, 

 not only relatively but also absolutely and as a rule with an increasing per- 

 centage of sugar. As a result of this relationship it is pointed out that the 

 sugar production per hectare fluctuates much less than the beet production and 

 the percentage of sugar content. In beet yield the variety Friedrichswerth, 

 among four varieties tested for eight years, ranked first with 42,392 kg. of 

 beets and 29,882 kg. of leaves per hectare. The average sugar content of the 

 beet, 16.22 per cent, was lower than in the other varieties but the average sugar 

 production per hectare, 6,876 kg., was the highest This was also generally 

 true of the results secured in the tests of shorter duration and with a larger 

 number of varieties. For sugar production the varieties Breustedt, Schobbert 

 Specialty 1, and Schobbert Ideal 1 ranked next to Friedrichswerth. 



The results with varieties of fodder beets showed that a decrease in beet 

 yield was accompanied by an increase in leaf production, not only in the per- 

 centage relation of the leaves to the beet, but also in the production per 

 hectare, and also in general by an increase in dry matter content. It is pointed 

 out that for this reason the dry matter yield per hectare varies less than the 

 beet yield and the percentage dry matter content. Of four varieties tested for 

 nine years, the leading variety. Yellow Eckendorf, yielded an average of 85,913 

 kg. of beets and 10,966 kg. of leaves per hectare. The average dry matter content 

 of the beet was 11.17 per cent. While this variety was the heaviest yielder of 

 beets, it fell behind the other sorts in dry matter content and dry matter pro- 

 duction, the average for the four varieties being 13.52 per cent and 10,314 kg. 

 per hectare respectively. Two varieties, Durana and Veni Vidi Vici, stood well 

 above the average in dry matter production per hectare. 



The test with rutabagas was conducted for only three years and limited to 

 only three varieties. The leading variety, Remy Improved Altmark Giant, 

 yielded 65,000 kg. of beets per hectare with a dry matter content of 12.57 

 per cent.
