130 EXPERIMENT STATION RECORD. 



Where winter wheat was sown on sod, double disking gave better results than 

 single disking or no disking, and sod broken in June or July produced a much bet- 

 ter yield per acre than sod broken in April. Winter wheat on soy-bean stubble 

 yielded 15.78 bu. per acre, and on corn stubble 12.33 bu. Notes are given on the 

 culture and value of Kafir corn, sorghum, and grasses. Of the grasses grown Pani- 

 cum bulbosum and /'. texanum made a promising growth. 



In 1904 the work begun in 1903 was continued. Among the varieties of winter 

 wheat tested were a number of hybrids, and the plants secured showed great varia- 

 tions. In 1902, 150 varieties were planted and by selection in 1903 and 1904 these 

 were increased in number to 350. ( hving to attacks of rust the yields of winter wheat 

 were low and the varieties of macaroni wheat were practically ruined. Barley and 

 rye also proved a failure. 



Of 6 varieties o.': oats Kherson gave much the best results, yielding 45.3 bu. per 

 acre. The best yield from seeding Texas Red oats at different rates was obtained 

 when 2 bu. of seed per acre was used. As in the previous season, harrowing and 

 packing after plowing proved the best treatment for winter wheat. The cultivation 

 of wheat by means of the harrow or the weeder was not profitable. 



In- 1904 surface-planted corn made a much more rapid growth and tasseled nearly 

 a week earlier than the listed corn, and also ripened about a week sooner. The 

 listed corn yielded 32.3 bu. and the surface-planted, 33.8 bu. per acre. Disking and 

 harrowing before plowing did not have a marked effect on the yield. 



The alfalfa sown on sod in 1902 gave favorable results in 1904, while the growth of 

 Bromus inermis on the fields seeded the same year was too small to make a hay crop. 

 Panicum bulbosum this season gave a very good yield. 



A rotation experiment is in progress for determining the influence of fallowing, 

 Kafir corn, oats, leguminous crops, and barley on the succeeding wheat crop. The 

 best yields of wheat were obtained in 1904 after fallow and after soy beans. 



Report on cultural tests in 1903-4, A. Damseaux (Bui. Agr. [Brussels], 21 

 (1905), No. 1, pp. 50-59). — Among a number of varieties of different cereals Abun- 

 dance wheat, Saxon rye, Hessian spelt, Hunsriick oats, and Groningen barley led in 

 yield. 



Schlitte sugar beet, the best of 4 varieties, gave a yield of 46,800 kg. per hectare, 

 with 15.70 per cent of sugar in the beet and a purity of 87.20. The application of 

 commercial fertilizers in the drill, as compared with applying the fertilizers broad- 

 cast, retarded the beets in their early growth, but they regained the time lost later 

 in the season. The results from applications of barnyard manure and commercial 

 fertilizers showed only slight differences in the yield and value of sugar beets, but 

 they indicated the importance of working the manure into the soil as early as possible. 



Fertilizer tests with potatoes proved inconclusive. An application of 2,500 kg. 

 lime per hectare increased the yield of Campine and Bohemian clover by 1,200 kg. 

 and of Lokeren clover by only 600 kg. Of a list of forage crops, excluding sacchaline, 

 crimson clover produced the largest yield of green substance. 



Results of fertilizer experiments in progress for ten years, C. von Seelhorst 

 (Jour. Landw., 53 (1905), No. 1, pp. 29-60).— The results of fertilizer tests with rye, 

 spring wheat, winter wheat, oats, barley, fodder beets, peas, beans, and potatoes are 

 discussed. 



The cereal crops were benefited only by nitrogen, potash and phosphoric acid 

 producing little or no effect. The yield of peas and beans was largely increased by 

 the use of potash, while nitrogen wa« also beneficial, but to a lesser degree. Nitrogen 

 followed by potash caused the greatest increase in the yield of fodder beets. With 

 potatoes the best results were secured where nitrogen and potash were given together. 

 The data obtained did not warrant drawing definite conclusions with regard to the 

 influence of the season on the action of the fertilizer.
