134 EXPERIMENT STATION EECORD. 



1,843 lbs. The manure was not so effective as in tlie other work. Alsike and 

 medium clover again gave better yields than mammoth. Sorrel, daisies, and 

 redtop were the chief plants growing with the clover. The untreated plats con- 

 tained approximately 76.5 per cent of grass, 1.5 per cent of clover, and 22 per 

 cent of weeds, and the limed 88 per cent of grass, 8 per cent of clover, and 4 

 per cent of weeds. The lime and muriate of potash plats contained 13 per cent 

 of clover, and the lime and complete fertilizer plats 10 per cent. 



The results of pot experiments with the silt loam soil were in the aggregate 

 the same as those obtained in the tield. They indicated the need of lime with 

 either manure or fertilizers. The greatest gain, which amounted to 71 per 

 cent, was secured with a complete fertilizer applied with lime. Nitrate of soda 

 applied with acid phosphate gave good results, but muriate of i)otash either 

 with or without lime was used without effect. An experiment with this same 

 soil conducted by the wire-basket method also showed the importance of manure 

 and pointed out the greater need of nitrogen and of phosphatic fertilizers than 

 of potash. 



Notes are given on lime and its use and a plan to conduct cooperative experi- 

 ments in the growth of clover is presented. 



Report on the propagation of resistant clover, S. M. Bain (Tennessee Sta., 

 Rpt. Coop, and Ext. Work Agr. Middle Tcnn. 1901-8, pp. 65-67).— This report 

 reviews the work done by the station in the propagation of strains of clover 

 resistant to anthracnose (Colletotrichum trifoUi) and reaifirms the statements 

 made in a previous bulletin (E, S. R., IS, p. 843). Advice as to how to guard 

 against the disease is also given. 



Clover-seed production in the Willamette Valley, Oregon, B. Hunter 

 ([/. S. Dept. Agr., Bur. Plant Indus. Circ. 28, pp. 15, figs. 2). — This circular 

 describes the methods used in the production of clover seed in this region. The 

 types of soil, the yield of seed, means of securing a stand, rotations, pasturing, 

 and clipping, the use of land plaster, and the manner of harvesting the clover 

 crop for seed are discussed. 



Corn, M. L. Bowman and B. W. Crossley (Des Moines, Iowa, 1908, pp. 4^9, 

 pis. 11, figs. 193, dgms. 6, charts IS, maps J/). — The discussions presented in this 

 book cover the various phases of corn growing, judging, breeding, feeding, and 

 marketing. The introductory chapter is devoted to the history of the corn plant, 

 and among the 21 succeeding chapters may be mentioned those devoted to cli- 

 mate and soil in relation to corn, seed corn, corn cultivation, harvesting and 

 storing, cost of growing, marketing, commercial products of corn, composition 

 and feeding value, corn silage, and judging corn. The last 3 chapters treat of 

 corn breeding. 



The effect of selection upon certain physical characters in the corn plant, 

 L. II. Smith (Illinois Sta. Bui. 132, pp. 51-62, figs. 5).— This bulletin reports 

 the results secured in selecting corn plants with a view to influencing the height 

 at which the ear is borne on the stalk and the position of the ear with refer- 

 ence to its declination from the stalk at maturity. 



In 1902, two sets of ears of Leaming corn, the one representing ears growing 

 high on the stalk and the other those borne low down on the plant, were se- 

 lected. The following year each set was planted in a breeding plat and the se- 

 lection for high and low ears continued each year. The results of this work 

 are summarized in the following table :
