534 EXPERIMENT STATION RECOED. 



cliick-pea are corrosive because covered with crystals of oxalates and other 

 hygroscopic salts which are thought to render the plant drought resistant by 

 condensing atmospheric humidity. Sesame grows on sandy clay soils where 

 the rainfall is 16 in. or less, but requires thorough preparation of the soil. Its 

 lack of uniformity in ripening necessitates several harvestings by hand. 



The author discusses the historical interest of wild wheat, the discovery of 

 wild emmer, the importance of the brittle rachis of the primitive cereals,ujaud 

 gives -an account of his rediscovery of wild emmer {Triticum dicoccuin dieoc- 

 coides) in Palestine and Syria. This prototype of true wheat was found in a 

 number of forms varying from 2 ft. high at Eosh Pinar to 40 in. at Rasheyya. 

 It is indigenous to the regions of ^Nlount Hermon, but rarely appears on culti- 

 vated soils. It is always found in company with wild barley. 



Cotton field and orchard of the experinient field in the Hunger Steppe in 

 1907, M. BiTSHUYEV (Abs. in ZJiur. Opuiln. Agron. (Russ. Jour. Expt. Latulir.), 

 10 {1909), No. 6, pp. 900, 901).— The field and garden crops most profitably 

 cultivated in the Hunger Steppe are alfalfa (fertilized with manure and super- 

 phosphate), cotton, beets, corn, sunflower, tobacco, winter barley, tomatoes, and 

 cucumbers. The more profitable orchard and forest trees in the same region 

 are jilum, apricot, peach, American ash, poplar, white acacia, and mulberry. 



[Variety and manurial tests and experimental sowings of field crops], 

 H. W. Potts et al. {Rpt. Dept. Agr. X. S. Wales, 1909, pp. 57-61, G.'t-66, 77-80, 

 90, 91 ) . — A progress report of experimental sowings of a large number of field 

 crops at different farms is given. 



At the Hawkesbury Agricultural College. Zealand and White Essex common 

 wheats produced 2 tons 11 cwt. and 2 tons 7 cwt. of hay per acre, respectively, 

 while among the macaroni wheats Velvet Don and Sarragolla produced 2 tons 

 10 cwt. and 2 tons 8 cwt. of liay per acre, respectively. Among 11 varieties of 

 oats Amarilla, Algerian, and White Tartarian produced yields of from 3 to 3^ 

 tons of hay per acre. In a fertilizer experiment with swedes, 150 lbs. of blood 

 apparently surpassed 1 cwt. of nitrate of soda or 95 lbs. of sulphate of ammonia 

 as a supplement to 200 lbs. of superphosiihate and 100 lbs. of sulphate of potash, 

 while with mangels the application of 2 cwt. of superphosphate per acre was 

 followed by a much larger yield than when the same amount of superphosphate 

 was used with kainit or nitrate of soda or both. Equal yields of corn followed 

 the application of (1) 84 lbs. of sulphate of ammonia and (2) a mixture of 140 

 lbs. of superphosphate, 84 lbs. of sulphate of potash, and 84 lbs. of sulphate of 

 ammonia. 



At the Wagga Experiment Farm, Algerian oats produced the maximum yields 

 of 56 bu. and 33 lbs. per aci'e. Limed and unlimed land produced substantially 

 the same yields without manure and with every application of fertilizer, except 

 one of 2 cwt. of superphosphate, in which case the yield on the limed land was 

 apparently increased 50 per cent. 



At the Glen Innes Experiment Farm. Bobs and Minnesota B. Stem wheats 

 produced the highest yields, 40 and 38 bu. per acre, respectively, while in a 

 field trial, Jonathan produced 30 bu. per acre. In a variety test of oats, the 

 maximum yield of hay was produced by White Tartarian. Among potatoes. 

 Factor produced the maximum yield of 6 tons 13^ cwt. 



At the Moree Irrigation Farm, Skinless barley cut for green feed and allowed 

 to head out again yielded 174 bu. per acre, while Algerian oats sown at the 

 rate of li bu. per acre on land irrigated twice and limed at the rate of 200 lbs. 

 per acre produced 2 tons Hi cwt. of hay. Alfalfa, sown at the rate of 12 lbs. 

 per acre through a drill from which the tubes had been removed from the 

 hose, promises satisfactory results. An even distribution of the seed was secured
