more grain per acre than did the Englisli varieties Browick Grey Chaff and 

 Carter White Stand Up. The French varieties, especially Marvel, showed many 

 ears affected by loose smut. 



Probsteier and White Horse oats gave equal average yields and somewhat 

 outyielded the other 4 varieties tested in tlie same 5 localities. 



Report on field trials on the manuring of seeds hay in 1909, J. F. Black- 

 SHAW (Midland Agr. and Dairy Go]. Bid. 2, 1909-10, pp. 15-25).— This is a 

 report of tests undertaken in 16 localities for the purpose of determining 

 whether seeds hay (rye grass and clover, one year's seeding) can profitably be 

 treated with artificial fertilizers. Nitrate of soda, superphosphate, sulphate of 

 ammonia, sulphate of potash, kainit, and muriate of potash were applied in 

 various mixtures and on various dates in March and April. Almost equal 

 3-year average profits followed the use of 200 lbs. of kainit and 50 lbs. of 

 muriate of potash, each in addition to a mixture of 100 lbs. of sulphate of 

 ammonia and 208 lbs. of superphosphate. These applications were all made 

 early in April except the potash which was applied early in March. Each of 

 the 8 other applications tested gave lower average profits. 



[Fertilizer and variety tests with meadow hay, swedes, and potatoes] 

 (Ann. Rpt. Cumberland and Westmoreland Farm School, 15 (1911), pp. 8-10). — 

 The 14-year average yield of meadow hay unfertilized was 30 cwt. per acre; 

 after an application of 10 tons of dung, 42 cwt. ; J cwt. nitrate of soda, li cwt. 

 kainit, and 3 cwt. basic slag, 38 cwt. ; 5 cwt. sulphate of ammonia, 1^ cwt. 

 kainit, and 3 cwt. of basic slag, 35 cwt. ; f cwt. nitrate of soda. 1^ cwt. kainit, 

 and 3 cwt. of superphosphate, 40 cwt.; and after an application of f cwt. of 

 sulphate of ammonia, 1* cwt. of kainit, and 3 cwt. of superphosphate, 36 cwt. 

 of hay per acre. 



Two-year average yields of 45 and 48 cwt. of hay per acre, respectively, fol- 

 lowed applications of (1) 5 cwt. of nitrate of lime, 1* cwt. of kainit, and 3 

 cwt. superphosphate, and (2) f cwt. of calcium cyanamid, 1^ cwt. kainit and 3 

 cwt. of supenihosphate. 



Five tons of swedes per acre were secured from the unfertilized plat as 

 compared with 31i tons after IJ cwt. of nitrate of lime. 2 cwt. kainit, and 

 5 cwt. of sui>erphosi)hate; 29 tons after the same mixtures of nitrate of lime 

 and kainit, with 5 cwt. basic slag instead of the superphosphate ; SOi tons after 

 1 cwt. nitrate of soda, 2 cwt. kainit, and 5 cwt. superphosphate; 31^ tons after 

 3 J cwt. kainit, and 7i cwt. basic slag ; 27i tons after 12 tons of dimg ; 32 

 cwt. after 12 tons of dung, i cwt. nitrate of lime, i cwt. kainit, and 11 cwt. 

 superphosphate; and 31* tons after an application of 1 ton of ground lime 

 stone in addition to the last named mixture. 



A variety test of potatoes is also reported. 



Trials with m.illets and sorghums for grain and hay in South Dakota, 

 A. N. Hume and M. Ciiamplin (South Dakota Sta. Bui. 135, pp. 309-336, figs. 

 8). — This bulletin rei>orts the results of experiments carried on in the years 

 1907-1910 at Highmore in cooperation with this Department. 



The highest average yield of grain secured from any variety of millet from 

 1907-1910 was 17.6 bu. per acre from common millet. The next highest average 

 yield was 16 bu. per acre from Black Voronezh, this being also practically the 

 yield from Kursk and Tambov millets. The Kursk varieties in 1910 produced 

 a higher yield of hay than the other varieties and yielded 24.7 bu. of grain, the 

 average of the highest yields of the variety for all seasons. Taking the yield 

 of hay and grain into consideration, the authors regard the Kursk millets as 

 the most promising. 



It was found that the grain sorghums require a longer time to mature than 

 millet. The average yield of grain per acre for 3 strains of grain sorghum for 

 3 years (1909-1911), including 2 extremely dry seasons, was 13.7 bu. per acre.
