FIELD CROPS. 765 



In the field corn and sorghum were grown on a marshy soil showing considerable 

 inequality. The corn plants which had made a good growth contained about 15 per 

 cent mure protein than the same weigh 1 of plants having made a poor growth. The 

 better developed plants of sorghum in the outer row had nearly 21 per cent inure 

 proteid nitrogen than good plants from the inner rows of the plat, and 51 per cenl 

 n Mire than poor plants, while good plants from the inner rows had 25 per cent more 

 than the poor plants. 



It is ci included that the relative ami unit <>!' protein in the plant varies considerably 



and is dependent upon tin nditions of growth, in which the fertility of the soil is 



an important factor. The results with sorghum in the field also indicated that the 

 distance (if planting exerts an influence in this connection. 



The pure culture method of soil inoculation, T. R. Robinson (South. Planter, 

 66 (196.',), No. 1, i>i>. 8-10). — This article describes in detail the method of soil inocu- 

 lation with pure cultures for growing clover and alfalfa and other leguminous crops 

 on uninoculated soil, and compares the same with the practice of using for this pur- 

 pose soil from old fields which have produced such crops. The commercial produc- 

 tion of the cultures is also mentioned. 



Unirrigated alfalfa on upland, J. E. Payne (Colorado Sta. Bui. 90, pp. SI 3 '■ \. 

 Instances of growing alfalfa as a forage crop on unirrigated land in eastern Colorado 

 are mentioned and notes on sowing the seed and on the location of the field are 

 given. Insect enemies and methods of combating them are also discussed. 



The influence of cultural methods on the yield of barley, S. Tretyakov 

 ( Khutoryanin, 1903, No. 45; ohs. in Zhur. Opuitn. Agron. [Buss. Jour. Expt. Landw.~\, 

 5 (1904), No, 4, pp. 540, 541)' — The effects of using barnyard manure in barley cul- 

 ture were observed on the Poltava Experiment Field from 1887 to 1895. Manure 

 applied to winter cereals 2 years before growing barley apparently produced an aver- 

 age increase of 32.3 per cent in the yield of grain and 38.3 per cent in the yield of 

 straw. In the rotation barley after a leguminous crop, such as alfalfa, gave even 

 better yields than after the application of barnyard manure. — p. fireman. 



The nitrogen content of barley and malt, Prior (Mitt. Osterr. Vers. Stat. n. 

 Akad. Brauind. Wien, 1904, pp. 1-5; separate from Attg. Ztschr. Bierbrau. u. Malzfa- 

 brik., 1904, May). — A discussion of the value of barley for malting in relation to its 

 nitrogen content. 



The distribution of nitrogenous material in barley, F. Jalowetz (Mill. 

 Osterr. Vers. Slut. a. Akad. Brauind. Wien, 1904, p- 1; separate from A/6/. Ztschr. 

 Bierbrau. ". Malzfabrik., 1904, May). — In the upper or germ end of the barley grain 

 the author found L.'.84 per cent nitrogen (water-free material), in the middle portion 

 1.79 per cent, and in the lower end 2.31 per cent. These observed data are dis- 

 cussed in relation to malting and brewing. 



Clover selection, F. \Y. Card and A. F. Stene i Rhode Island Sta. Rpt. 1904, ]>j>- 

 W2-20~>). — An experiment begun with the view to studying the individuality of 

 clover plants is described, and a report of progress for the season is given. The 

 work thus far calls attention to the great variation in clover plants grown from com- 

 mercial seed. 



Corn culture, R. J. Redding (Georgia Sta. Bid. 65, j>j>. 185-198). — This bulletin 

 presents the usual report on the corn culture experiments of the station, previously 

 noted ( K. S. I:., 14, ]). 855). In addition to experimental results, the meteorological 

 data lor this and pre\ ions seasons are given and the importance and method of seed 

 corn selection discussed. 



Fourteen varieties grown in 1904 gave an average yield of 20.88 bu. per acre. 

 Marlboro and Albemarle headed the list with L'tj and •_'.">. 25 bu. per acre, respectively. 

 During the years 1895 to 1904, inclusive, the best, varieties tested have given an 

 average of 10.87 bu. more per acre than the poorest varieties. The results of two 

 experiments with fertilizers indicated that concentrated fertilizers produced but
