year are the most important factors tending to decrease tin- yield of hay crops. 

 Among the causes tending to increase the j'ield are a low average temperature and 

 heavy precipitation in May, a beavj precipitation in September, a high temperature 

 and heavy precipitation in November, and ;i high average temperature in December 

 of the preceding year, and a heavy precipitation in May and June, and a low average 

 temperature in June of the same year. — k. w. woll. 



Effect of time of cutting- on the yield and composition of hay, S. II \i- 

 (Tid88kr. Norske Landbr., i .' [1905), No. ?, pp. :: 88). Plate of a third-year timothy 

 and a first-year clover field were cu1 on 3 differenl dates in .Inn. • ami .Inly. The 

 quantities of protein secured in the second cutting, when timothy was beginning to 

 bloom and the clover was in full bl i, were higher than in either of the other cut- 

 tings. Tln> same was true with reference to phosphoric acid, potash, and lime, bul 

 the differences here were only small as compared with the firstcutting. i. w. woll. 



The protein content of barley and potash manuring, 0. Reitmaib [Ztschr. 

 Landw, Vermchsw. Oesterr., 8 {1905), No. //, pp. 988 1014). The results of 30 

 cooperative fertilizer tests with barley are reported and discussed. 



In a series of 14 tests made under the direction of the author the crop followed 

 sugar beets on deep, fertile, loam soils. Bach individual experimenl comprised 2 

 unfertilized plats in addition to l receiving 75 kg. of nitrate of soda and 200 kg. of 

 superphosphate per hectare, and another receiving together with this application 200 

 kg. of 40 per rent potash salt. The use of nitrate of soda and superphosphate appar- 

 entlj increased the yield per hectare by 216 kg. and the use of potash by 104 

 kg., but in both cases this increase did not cover the outlay. In 3 of these tests the 

 application of potash seemed to have reduced the protein content, while in the 

 remaining experiments no reduction was apparent. 



Similar results were obtained in a second series of 16 tests, supervised by A. Man- 

 ner. The author states that in the 30 tests under consideration potash fertilization 

 has not shown the ..effect of reducing the protein content, but on the contrary, rather 

 a tendency to increase it. It is believed that all other factors of growth, especially 

 total temperatures and moisture, have a greater influence on the quality of the barley 

 than the fertilizer applied. 



In over 80 percent of the tests the addition of potash seemed to have increased the 

 weight of the grain. The results of other experiments indicating that potash fertili- 

 zation does not reduce the protein content of barley, bu1 docs exert a favorable 

 influence on the weight of the grain, are reviewed. In one of these tests the use of 

 phosphoric acid seemed to have reduced the protein content of the barley. 



The second part of this report is a refutation of the stand taken by Stoklasa with 

 reference to this problem. 



The use of whole and halved fodder beets in seed production, II. Briem 

 i F&hling's Landw. Ztg., 54 | 1905 ), .V". ..'/, />/>. 788-788). — In discussing the subject the 

 author points to an instance in which only 370 out of 2,000 well-formed and heavy 

 -elected beets were found rich enough to be used as mother beets. 



The BUgar content in the entire selection varied from 2 to !•"> per cent, and in the 

 heets used for seed the minimum sugar content was S percent. It is held that under 

 BUCh circumstances the maximum production of seed from a single individual is most 

 important, and experiments are reported comparing the yield of seed from individual 

 heets planted whole and when divided into 2 equal part- and planted separately. 

 Forty whole heets of the .Mammoth variety produced 6,300 gm. of seed and ID indi- 

 viduals grown from halves produced 1,900 gm., the relation being as LOOto L55 when 

 the yield of 1 whole beet and 2 halves are taken into consideration.
