605. Ferris, E. B. Cotton growing in south Mississippi. Mississippi Agric. Exp. Sta. 

 Bull. 196. 8 p. 1920. — Cotton yields in south Mississippi are very uncertain on account of 

 heavy boll weevil damage. Trice is the best variety, and Cleveland probably next. 300 

 lbs. acid phosphate per acre and some nitrogen carrier are recommended as fertilizers. — 

 H. B. Brown. 



GOG. Ferris, E. B. Report from south Mississippi Branch Experiment Station for 1918 

 to 1920 inclusive. Mississippi Agric. Exp. Sta. Bull. 194. 23i). 1929.— This report gives 

 a history of the South Mississippi Station and results from experiments conducted in 1919 

 and 1920.— i/. B. Brown.

608. GiROLA, Carlos D. Algo sobre cuestiones forrajeras. [Forage crop problems.] 

 Publ. Mus. Agric. Republica Argentina 22 : 1-7. 1920. — Careful consideration should be given 

 to the problem of providing pasturage to maintain and increase the live stock industry of 

 Argentina, which in 1918 had a total export value of 500,000,000 pesos gold. Various plants, 

 among them Atriplex semibaccata, Pohjgonum sachalinense, Symphytum asperrimum, and var- 

 ious of the sorghums have been exploited but are unsatisfactory except under especial limited 

 conditions. Alfalfa will take first rank among the forage crops of the country with a planted 

 area of 10,000,000 hectares. Rye grass, brome grass, the Paspalums and other grasses have 

 proven satisfactory when properly cultivated. — John A. Stevenson.

610. Harlan, Harry V., and Stephen Anthony. Effect of time of irrigation on kernel 

 development of barley. Jour. Agric. Res. 21: 29-45. £0 fig. 1921. — "At Aberdeen, Idaho, 

 deposit of dry matter in the barley (Hordeum) kernel continues until very near the point of 

 absolute ripeness. The plants are able to utilize water up to the date of full maturity." 

 Late irrigation results in a later maturity. Shortage of water even when the spikes are turn- 

 ing yellow stops the depositing of dry matter. Shortage of water during the early develop- 

 ment of the kernel probably determines the size of the kernel, even before the rate of deposit- 

 ing of dry matter is checked. — D. Reddick. 



611. Harth, E. Zwiebelanbauversuche im Jahre 1920. [Onion culture investigations 

 in 1920.] Mitteil. Deutsch. Landw. Ges. 36: 254-257. 1921. — Four varieties of onions were 

 tested in 7 sections. Much of the information is given in tabular form and covers shape, 

 size, and color of bulb, and yields of marketable and unmarketable bulbs. — A. J. Pieters. 



612. Haywood, A. H. The culture of sugar cane in New South Wales. Agric. Gaz. 

 New South Wales 31: 773-780, 853-859. 1920; 32: 28-32, 181-184, 257-2C0. 13 fig. 1921.— 

 The area devoted to sugarcane is along rivers on the north coast of New South Wales. The 

 acreage in 1895 was 33,000, which was gradually reduced to 11,000 by 1917; yield of sugar per 

 acre has increased. The author discusses various phases of sugar cane culture in common 

 practice from the preparation of the land to the harvesting of the crop. Important varieties 

 are described, and some of these are figured. Four diseases, — gumming, leaf-scald, Fiji 

 disease, and yellow stripe, — are described and discussed as to prevention and control. — 

 L. R. Waldron. 



613. Jones, D. F. Connecticut round tip tobacco. A new type of wrapper leaf . Connecti- 

 cut [New Haven] Agric. Exp. Sta. Bull. 228. 2S7-292, pi. 16-17, fig. 1-4. 1921.— A description 

 of a new variety of tobacco developed by hybridization and selection is given. The tip of 

 the leaf is round permitting the cutting of a larger number of wrappers than can be had from 

 the leaf of the varieties usually grown in the state. Field tests on farms for 4 years indicate 

 that the variety is productive and has merit as a wrapper leaf. — Henry Dorsey.
