438 EXPEEIMENT STATION RECOED. 



certain detrimental organisms in the soil. Tobacco seeds stiould not be sown 

 on the beds until at least 24 hours after sterilization. Seed beds should not 

 be too heavily fertilized, but should be well supplied with nitrogen. . . . The 

 fertilizers should be applied before sterilizing. 



" Tobacco seed should be sown without being previously forced to germinate. 

 Seeds should not be sown too thickly, for too heavy seeding results in crowded 

 plants with poor roots. Beds covered with muslin are cheaper and easier to 

 water than glass-covered beds, though the latter cause faster growth. Beds 

 should be ventilated occasionally, and kept moist but not too wet. When 

 weather conditions permit, covers should be removed about a week before 

 planting time, so as to allow the plants to harden." 



In fertilizing, the best results were obtained by using at the rate of 20,000 

 lbs. barnyai'd manure, 1,600 lbs. cotton-seed meal, 400 lbs. acid phosphate, and 

 200 lbs. sulphate of potash per acre, and the bed seeded at the rate of 1 oz. 

 per 900 sq. ft. 



Wheat investigation (NebrasJca Sta. Rpt. WIS, pp. IX, X). — This gives 

 results which show about 4.7 bu. increase in yield by the use of selected strains 

 of Turkey Red wheat over local seed, obtained by several farmers throughout 

 /the State in 1911-12. 



The culture of winter wheat in the Eastern United States, C. E. Leiohty 

 (17. S. Dept. Agr., Farmers' Bui. 596 (1914), pp. 12, figs. 2).— This gives cul- 

 tural and harvesting notes for the production of winter wheat in the Eastern 

 States. 



The quality of clover and vetch seed found in Maryland markets in 1913, 

 C. P. Smith {Maryland Sta. Bui. 119 (Wl-'f), pp. 59-88).— This bulletin gives 

 the results of inspection of samples of red, crimson, white, alsike, and sweet 

 clovers, alfalfa, and hairy vetch found on the market in 1913. 



Weeds, H. S. Coe {Soiith Dakota Sta. Bnh 150 (1914), pp. 380-453, figs. 29).— 

 This bulletin discusses weeds in general, their manner of dissemination, and 

 the losses they cause, and describes in detail, giving methods of eradication 

 cf each, about 50 of the more common weeds. 



How to rid our farms of weeds, A. L. Stone {Wisconsin Sta. Circ. 48 {1914), 

 pp. 3-24, figs. 14). — This circular describes quack grass and Canada thistle and 

 gives means of eradication for large and small areas, besides discussing the 

 detrimental action of weeds in general. 



HORTICULTTJKE. 



Vegetable gardening, H. P. Stuckey {Georgia Sta. Bid. 106 {1914), PP- 

 49-91, figs. 17). — This bulletin contains practical directions for the culture of 

 various vegetables, the subject matter being largely based on data secured 

 from cultural experiments conducted by the station during the past five years. 

 Some brief notes on the results of these experiments are included. The bul- 

 letin concludes with a paper on combating insect pests and fungus diseases 

 of garden plants, prepared by B. B. Higgins and H. P. Stuckey. 



In 1910 some crosses were made between the cabbage and collard in an effort 

 to obtain new types of collards for breeding strains superior to the common 

 collard. The collard was taken as the seed parent. Data are given on the 

 characteristics of the first and second generation plants. Among these off- 

 spring were a number which are considered decided improvements over the 

 ordinary collards. An effort will be made to perpetuate these types. 



In a variety test of Irish potatoes it was found on the whole that the early 

 maturing varieties gave the lightest yield. A test was made of the comparative 

 effect on the yield of Irish potatoes from turning under a heavy summer cover
