432 EXPERIMENT STATION RECORD. 



prove adapted to Florida conditions, it is expected to be a good soil renovator 

 and a valuable forage crop. 



Plats from which cowpeas and sorghum were harvested about the same time 

 were plowed, harrowed, and sowed to Dwarf Essex rape. The total yields 

 from 2 cuttings of rape grown after cowpeas was 4.4 tons, as compared with 

 0.96 ton after sorghum. Among 18 varieties of sweet potatoes tested for value 

 as stock food and for commercial purposes the Red Yam, Brown Seedling, and 

 Bunch Yam produced total yields of more than 350 bu. per acre each. 



Lessons from recent crop experiments, J. G. Stewart (Trans. Highland and 

 Agr. Soc. Scot., 5. .scr., 22 {1910), pp. 61-15, figs. 10). — Recent experiments at 

 the various agricultural colleges throughout the United Kingdom with wheat, 

 barley, oats, red clover, turnips, thousand-headed kale, and potatoes are briefly 

 summarized. It is noted that drilling wheat usually saves a bushel of seed per 

 acre, and that applications of salt at the rate of 5 cwt. per acre shortly before 

 seeding had no marked effect upon the stiffness of barley straw, but markedly 

 increased the yield of both grain and straw. The Potato oat excels the best of 

 the newer varieties in quality or palatability of straw but not in yield of meal. 



Cooperative field trials, 1908—9, B. R. Larsen {Norges Landbr. Hoiskoles 

 Akervckst. Aarshcr., 1908-9, pp. 7'/ + 15, figs. 2). — This is the twentieth annual 

 report of trials conducted under the direction of the author at the Aas Agri- 

 cultural College of Norway and on farms in different parts of the country. 

 During the year 355 trials, comprising 5,988 plats, were conducted, including 

 variety tests with cereals, root crops, hay crops, and inoculation trials with 

 peas, lupines, and other legumes. Experiments on the influence of fall and 

 spring pasturing on the hay crop and the comparative value of different fer- 

 tilizers on grass land are also reported. 



Report of the Hedemarken County Experiment Station, 1909, W. Christie 

 {Ber. Iledcinarkeiis Amts Forsogsstat. Yirks.. 5 {1909), pp. 55, pis. 7). — Variety 

 tests with turnips conducted during 1906-1909, trials of farm manure and arti- 

 ficial fertilizers as top-dressings for meadows in northern Oesterdalen, 1908 to 

 1909, and investigations of the starch content of Norwegian potatoes, 1909, and 

 of old Norwegian oat varieties in 1908-9 (noted on page 438) are reported. 



Beport of the substation of the Swedish Seed Association at Lulea, A. 

 Ulander {Svcrigcs Utsddesfdr. Tidskr., 20 {1910), No. 1, pp. 83-53, pis. 6).— 

 Trials with pure-bred strains of grasses and legumes and also of barley and 

 oats are reported. 



Annual report of the agricultural stations in Eastern Bengal and Assam 

 for the year ending June 30, 1909 {Ann. Rpt. Agr. Stas. East. Bengal and 

 Assam, 1909, pp. 136, maps .'/). — At the Dacca station a test of 11 varieties of 

 winter rice proved a failure because of dry weather, but the local varieties stood 

 the drought better than imported varieties. Manurial experiments with this 

 crop indicated that bone meal applied alone is more profitable than when 

 soluble nitrogenous fertilizer was added. Sann was a failure as a green manure 

 because it died out soon after germination. Dhaincha grew better but was only 

 about a foot high when plowed under. Other materials tested were saltpeter, 

 sulphate of ammonia, calcium nitrate, cotton cake, and fish manure singly and 

 in various combinations. As only one year's data are available, definite con- 

 clusions are withheld. 



At the Burirhat station 9 different classes of tobacco of numerous varieties 

 were tested and the results, given in tabular form, include the source of seed, 

 area planted, time of transplanting, date and method of harvesting, the fer- 

 tilizers applied, and the character of the rotation in which the crop was grown. 

 Cochin, calicut, and Jamaica ginger were tested together with the local varieties, 

 but all were attacked by Pythium gracile.
