854 EXPEEIMENT STATION RECOKD, 



The results of the tests indicate that lieavier apphcations would not be profitable. 

 Superphosphate gave better results than Thomas slag. The sugar content of beets 

 and the starch content of potatoes was not increased by fertilizing witli jihosphoric 

 acid. 



Owing to the large amounts of potash given the soil in barnyard manure, potash 

 salts were not profitable for either cereals or root crops when aj^plied with barnyard 

 manure. Potash had no detrimental effect on the quality of sugar beets, but it low- 

 ered the starch content of potatoes. On the soil in question 40 per cent potash salt 

 is considered jireferable to kainit and the following quantities jier morgen are recom- 

 mended: Sugar beets 1.5 cMt., potatoes 1 cwt., and cereals 0.75 cwt. The use of 

 potash every year did not seem advisable. 



Variety tests with square head wheats show the l)est j-ields from Beseler Square 

 Head No. 8. Among other varieties the wheat known as "Salischer Sandweizen" 

 gave the largest yield. This variety also proved richest in protein and best for bread 

 making of all the varieties grown. Hanna barley stood first among spring varieties 

 and Bestehorn Giant Winter barley among winter varieties. Eckendorfer Mammut 

 was the earliest variety of barley under experiment. Beseler No. 1 and No. 2 were 

 the best yielding varieties of oats. 



The average yield of dry matter in field V)eets for a series of years amounted to 

 9,900 kg. per hectare, while sugar beets, given high fertilizer ai^plications, yielded 

 12,000 kg. In 1901, however, field beets and sugar beets yielded about equal (juanti- 

 ties of dry matter. It is stated that 20 lbs. of sugar beets furnish about the same 

 quantity of nutritive material as 50 lbs. of field beets. Owing to their low moisture 

 content sugar beets keep much better in storage than field beets. The nutritive 

 value of the dry matter in either variety is determined by the sugar content. 



Extensive tables are given showing the composition of the crops under test ;uid 

 the quantities ol jilant food they withdrew from the soil. 



Fertilizer experiments on meadows, Edler (/)(?«/. lAindir. Presse, .10 {J90S), 

 No. 16, p. 13S, figs. 4)- — Thirty-one cooperative tests with kainit, Thomas slag, and 

 nitrate of soda as fertilizers for meadows are reported. The different fertilizers were 

 applied alone and in different combinations at the rate of 1,000, 800, and 100 kg. per 

 hectare, respectively. The combined use of the fertilizers gave the best results, and 

 the author concludes that the application of nitrogen in addition to potash and phos- 

 phoric acid on meadows is more profitable than is generally supposed. 



Kainit and 40 per cent potash salts as fertilizers for cereals, H. Bachmann 

 {Dent. Lanchv. Presse, 30 {1903), No. 15, p. 120). — The results of cooperative fertilizer 

 experiments are reported in tabular form. The use of 40 per cent potash salts applied 

 in the spring gave a larger increase in the yield of oats and a smaller increase in the 

 yield of straw than kainit. Lime given in connection with these potash salts did not 

 change the relation of the results. With sugar beets kainit applied in the fall was 

 more effective than 40 per cent potash salt, but Mhen the applications were made in 

 the spring kainit was the less effective of the 2 fertilizers. Kainit gave the better 

 financial returns and in all cases showed the greater residual effect. 



Variety tests of barley and oats, C. Fruu'irth ( Vergleichende Anbau- ]'c):'<iirJu' 

 mit verschiedenen Gerde imd Hafersorten. Plieningcn: Friedrich, Find, 1903, pp. 68). — 

 The varieties of barley under test included Trotha Chevalier, Hanna, Selchower, 

 Princess, and Goldthorpe, and those of oats Albhafer, Duppauer, Sechsaemter, Heine 

 Ertragreichster, Heine Trauben, Beseler, and Carter Golden. Each variety is 

 described at some length, together with the results obtained in the experiments. 

 The experiments extended over a period of 3 years.
