FIELD CROPS. 37 



With cauliflower tlie pl.-its all gave profitable returns, tlie largest being from 

 the sulphate of ammonia plat. 



All of the plats in the experiment received P2O5 and K2O to make up a com- 

 plete fertilizer for the crops. 



Comparative fertilizer experiments with cereals in 1912, Wehnert 

 (Landtc. Wchnbl. Schles. Hoist., 63 (1913), No. 51, pp. 1010-1016).— In testing 

 the value of lime nitrogen, nitrate of soda, and sulphate of ammonia on oats 

 and barley the best yields of grain and straw were obtained with sulphate of 

 ammonia in general on all classes of soil tested. 



Soy beans and cowpeas, A. T. Wiancko, M. L. Fisher, and C. O. Ckomer 

 (Indiana iita. Bui. 172 {191/f), pp. 421-Jf38, figs. 8). — This bulletin, continuing 

 jjrevious work (E. S. R., 18, p. 103S), reports tests of cultural methods suited 

 to Indiana conditions, includes some historical notes, and describes 18 varieties 

 of soy beans and 11 varieties of cowpeas with yield data. 



It is noted that both soy beans and cowpeas are well adapted to the climatic 

 conditions of Indiana and that they have a wider soil adaptation than most of 

 the -common crops. One of the most important uses is regarded as sowing after 

 harvest, on wheat or oat stubble, early potatoes, cannery peas, and as an orchard 

 cover crop. Used in this way data show that after wheat, for the years 1909- 

 1912, the average yield per acre of soy beans in green weight of tops was 10,660 

 lbs. and of roots to a depth of 18 in., 2,355 lbs., containing Sl.S and 10.9 lbs. of 

 nitrogen, respectively. The average yield per acre of cowpeas in green weight 

 of tops was 12,872 lbs. and of roots to the depth of 18 in. 2,691 lbs., containing 

 96.2 and 16.7 lbs. nitrogen, respectively. 



Several years' experiments on methods and rates of planting soy beans for 

 seed and hay production show that solid drilled, using about 60 lbs. seed per 

 acre, gave larger yields per acre of both grain (21.7 bu.) and of hay (6,368 lbs.) 

 than drilling in rows 24, 28, 32, 40, and 42 in. apart or broadcast. The seed 

 yields with cowpeas were too small to warrant conclusions. 



Chemical analyses, P. Bigler (Relat. Min. Agr. Indus, e Com., Brazil, No. 

 2 (1911), pp. 180-183). — ^This gives in tabular form very complete analyses of 

 28 samples of sugar cane and of 81 samples of cassava. 



Grass mixtures for North Carolina pastures, C. B. Williams (North 

 Carolina 8ta. Circ. 9 (1913), pp. 6). — Grass mixtures for permanent pastures 

 in the coastal plains, Piedmont, and mountainous sections for uplands and 

 lowlands are given, together with cultural notes. 



The creeping rootstock of Agropyron repens, Margery Knight (Jour. Bot. 

 [London], 51 (1913), No. 612, pp. 3^1-343, pi. 1).— This article describes the 

 plant as a whole and the structure of the stem, the structure and development 

 of the leaf, and the origin of the leaf and roots. 



Alfalfa in Kansas, W. M. Jardine and L. E. Call (Kansas 8ta. Bui. 197 

 (1914), PP- 577-610 figs. 15). — This bulletin gives data on cultural methods, 

 including inoculation, row seeding, handling of hay and seed crop, influence 

 of alfalfa on soil fertility and on succeeding crops, rotation, and animal and 

 insect pests. 



The effect of 10 tons per acre of barnyard manure applied to wheat before 

 seeding to alfalfa in 1907 on an old cultivated fleld was as follows : Yield of 

 alfalfa in 1908, manured 8,560 lbs., unmanured 4,104 lbs. ; in 1909, manured 

 31,856 lbs., unmanured 8,541 lbs. The effect of acid phosphate for 4 seasons. 

 1910-1913, was shown in an increased net income of $8.74 per acre. See also a 

 previous note (E. S. R., 20, p. 473).
