528 EXPERIMENT STATION RECORD. [Vol.41 



Heavy parent hills of sv.^eet potatoes planted April 5 and 27 produced 0.15 lb. 

 per plant, or approximately 15 bii. per acre, more than li^ht hills. Plantings 

 made on June 25 from cuttings failed to show any correlation between the 

 yield of parent hill and offspring plantings. 



Brief notes are presented on certain promising new grasses, including i'cnni- 

 setum purpureuni , P. merkeri, P. longistylmn, EriocMoa suhglahra, Osterdamia 

 matrella, Digitaria didactyla, Paspalum notatum, Chrysopogon montcnms, 

 Brachiaria plantaginea, and Andropogon faveolatus. See also a previous note 

 (E. S. R., 41, p. 37).

 1917 and 1918] {Bie^i. Rpt. Bd. Farm Comrs. [Wyo.], 1917-18, pp. 3-102, pis. 

 15). — Continuing work previously noted (E. S. R., 39, p. 229), numerous field 

 tests conducted at several centers in the State with grain and forage crops are 

 described. 



[Report of work with, field crops on the Canada Experimental Farms, 

 1917], J. H. Grisdale et al. (Canada Expt. Farms Rpt. PJIS, pp. 9, 10, 12, 13, 

 U, 15, 20-22, 25-27, 34, 35-37, 43-45, 48-50, 51-60, 63, 68-70, 74, 75, 80-82, 86,

 130, 131, 133, 136, 137, 142-144, 146, i^7).— This briefly describes the progress of 

 work conducted along the same general lines as previously noted (E. S. R., 

 40, p. 735), embracing variety, fertilizer, rotation, and cultural tests with 

 wheat, oats, barley, rye, field peas, flax. hemp, alfalfa, grasses, corn for forage, 

 sugar beets, potatoes, turnips, mangels, carrots, vetches, clovers, rape, and 

 tobacco. Plant breeding work with cereals is also noted. 



[Report of field crops work in St. Vincent, 1917-18], P. Watts (Imp. 

 Dept. Agr. West Indies, Rpt. Agr. Dept. St. Vincent, 1917-18. pp. 3-10, 15-23).— 

 This notes the progress of work along the same general lines as previously 

 indicated (E. S. R., 39, p. 835), including manurial experiments with Sea 

 Island cotton, reported on in more detail elsewhere (E. S. R., 40. p. 627), 

 and arrowroot, and breeding work with cowpeas, Doliclios lablab, castor bean, 

 and tomatoes. Statistical information is also given relative to the production 

 in the island of cotton, corn, arrowroot and cassava for starch, sugar cane, 

 peanuts, and peas. 



Arrowroot mulched with prunings of Gliricidia muculata produced on the 

 average .53,950 lbs. of rhizomes per acre as compared with 17,371 lbs. from 

 the untreated plats. In a comparison of different artificial and organic 

 manures, an average yield of 49,385 lbs. per acre followed mulching with Gliri- 

 cidia prunings, with an application of phosphate and potash next in order with 

 30,088 lbs., as compared with 20,439 lbs. from the untreated check. 



[Report of field crops work in British Guiana, 1917], J. B. Harrison (Rpt. 

 Dept. Sci. and Agr. Brit. Guiana, 1917, pp. 6-22). — Variety tests, hybridization 

 and selection studies, and fertilizer experiments with sugar cane and variety 

 tests with rice are described for the year ended December 31, 1917, in a 

 continuation of similar work previously noted (E. S. R.. 40, p. 242). 



[Report of field crops work in the Union of South Africa, 1918], F. B. 

 Smith, W. H. Scheeffius, H. S. du Toit, and W. Pyott (Union So. Africa 

 Dept. Agr. Rpt. 1917-18, pp. 15, 23, 2//, 25, 30-33, 69-71, 145-147, 155-158).— The 

 work of the tobacco and cotton, grain, and dry-farming divisions for the year 

 ended March 31, 1918, is outlined as heretofore (E. S. R., 40, p. 524), together 

 with information relative to the acreage and production of corn, wheat, oats, 

 barley, Kafir corn, potatoes, sugar cane, and miscellaneous forage crops. The 

 report of the chief grain inspector is included.
