FIELD CROPS. 435 



toes, linseed, peanuts, dry-land rice, maize, oats, wheat, stock melon, Boer 

 manna, teff grass, velvet beans, Kafir beans, root crops, chicory, and buckwheat. 



Beport of the agriculturist and botanist, II. G. Mundy {South. Rhodesia 

 Rpt. Dir. Agr., 1912, pp. 33-40).— This report gives notes on a continuation of 

 work mentioned above with additional data on barley, monkey nuts, and rye. 



The breeding work at Svalof, C. Fruwibth (Monatsh. Landw., 6 (1915), 

 No. 7, pp. 193-207).— This paper describes the work in plant breeding that is 

 being done at this Swedish station, and discusses some results and the prin- 

 ciples involved. 



Experiments in dry farming (Agr. Jour. Union So. Africa, 5 {1913), 'So. 6, 

 pp. 925-930).— Here are given in tabular form data on results of growing the 

 following crops in 1912 at the dry-land station at Lichteuburg: Soy beans, 

 potatoes, maize, teff grass, flax, peas, millet, sunflower, cowpeas, vetch, lupines, 

 velvet beans, Kafir beans, barley, wheat, rye, peanuts, alfalfa, sainfoin, Pha- 

 laris hulhosa, cotton, coriander, ginger, clovers, beggar weed, Bromus inermis, 

 forest trees, apples, and Spanish reeds. 



Dry land pastures {Rhodesia Agr. Jour., 10 {1912), No. 2, pp. 244-246). — 

 This article mentions as desirable Paspalum dilatatum as a summer pasture 

 grass, and Phalaris bulbosa as a winter pasture grass, both having given good 

 results on dry lands in Rhodesia. 



On the appropriation of nitrogen by legumes, A. Herke {KisMet. Kozlem., 

 15 {1912), No. 5, pp. 790-800).— Through his experiments the author concludes 

 that when the soil contains sufficient assimilable nitrogen the presence of nod- 

 ules on the roots has no influence on the nitrogen content of lupines. When 

 the soil is poor in nitrogen the presence of nodules increases the absolute as 

 well as the percentage of nitrogen content of the plant. It is noted that the 

 greater the percentage of nodules to plant, by weight, the greater is the per- 

 centage of nitrogen in the plant (with nodules removed), but when the per- 

 centage of nodules becomes large the nitrogen content of the plant does not 

 increase by further growth of the nodules. It was also determined that the 

 dry matter, the nodule growth, and the nitrogen content of the plant may con- 

 tinue to increase after the flowering stage. The percentage of nitrogen in 

 the dry matter of the nodules varied from 5 to 7 per cent, and 57.43 per cent 

 of this nitrogen was soluble in water. 



The action of sulphur as a fertilizer, M. A. Demolon {Sta. Agron. Aisne 

 Bui., 1912, pp. 33-41). — Results of experiments are given in which flowers of 

 sulphur at the rate of 10 gm. per square meter increased the yield of ruta- 

 bagas, parsnips, and beets. The applications of sulphur to the soil seemed to 

 give rise to slightly increased quantities of sulphate. Sulphur applications at 

 the rate of 100 kg. per hectare (89 lbs. per acre) increased the yields of pota- 

 toes, but not of carrots. 



The cultivation of cereals with the aid of new appliances and by new 

 methods, C. Is%aus {Landw. Eefte, 1913, No. 22, pp. 48, figs. 5). — The author 

 describes and digcusses the use of recently introduced machines and appli- 

 ances for securing the most perfect seed bed, as well as methods of hilling, 

 drilling, and seeding in furrows. Some results of recent experimental work 

 are quoted in discussing the practicability of these methods. 



[Alfalfa production] {Ann. Rpt. III. Fanners' Inst., 17 {1912), pp. 173-205, 

 348-353, figs. 2).— In this article A. P. Grout, G. F. Tullock, and others relate 

 their experiences in producing alfalfa in various parts of Illinois and on sev- 

 eral soil types, ranging from heavy rich bottom and drained lands to the light, 

 poor soils of the State. Two papers are included. The Value of Alfalfa on 

 Average Illinois Farms, by A. N. Abbott, and How To Secure a 95 per cent 

 Perfect Stand of Com, by F. I. Mann.
