334 EXPERIMENT STATION RECORD. [Vol. 37 



Some study has been made of fertilizing permanent lowland moor pastures 

 with commercial fertilizers, indicating that good results may be expected. 



Green manuring in India, A. C. Dobbs (Agr. Research Inst. Pin^n Bui. 56 

 {1915), pp. 55, pis. 7, figs. 2). — This is a comprehensive discussion of the theory 

 and practice of green manuring as applied to agricultural conditions in India, 

 consisting chiefly of a compilation of data from various sources. 



Color variation in seed crops of cultivated legumes, F. G. Galang {Philip- 

 pine Agr. and Forester, 5 {1916), No. 3, pp. 19-101). — This is a preliminary 

 report of an attempt at simple selection with certain legumes, based on see<l 

 color. The crops used were as follows: Yigna sinensis (three varieties). 

 Glycine hispida, Cyamopsis psoraleoides, Phaseolu^ calcaratus, P. lunatus, 

 PsopJiocarpus tetragonolobus (two varieties), Dolichos biflorus, Centrosemn 

 plumicri, and Cajanus cajan. The color of the original seed planted is described 

 in detail for each variety, and the color variations obtained from the different 

 colored seeds of the different varieties are tabulated and discussed for each 

 group of see<ls, but no definite conclusions are drawn. 



Alfalfa in Wyoming, T. S. Parsons {Wyoming Sta. Bui. Ill {1916). pp. 

 19-55, figs. 6). — The field practices employed in the production of alfalfa in 

 Wyoming are discus.sed Id detail, and variety and cultural tests for 1911 to 

 1915, inclusive, are reported. 



The field experiments for each year of the five-year {leriod are outlined and 

 the results briefly summarized. Grimm alfalfa gave an average yield of 5.25 

 tons per acre for the 5-year period, leading all other varieties in yield, hardi- 

 ness, and earliness of maturity. Broadcasting gave as good results as drilling 

 the seetl. Summer fallow put the soil in the best condition for alfalfa. An 

 average hay yield of 1 ton per acre was obtained the first year when a nurse 

 crop was used. No advantage was gained from liming or from inoculation on 

 the experimental plats at Laramie. A seeding rate of 10 Ib.s. per acre was found 

 ample in all cases, and one irrigation per cutting was usually sufficient. A 

 well-packed seed bed with a loose surface, good seed, and suflicient moisture to 

 insure germination are deemed to be the es.<:ential factors for successful alfalfa 

 growing under conditions similar to those on the station farm. 



Barley in Washington, E. G. Sciiafer and E. F. Gaines {Washington Sta. 

 Bui. IJfl {1917), pp. S-12, figs. S). — Comparative observations of winter and 

 spring wheat, spring oats, and winter and spring barley for 1914. 1915, and 

 191fi indicate that .spring barley produces the heaviest yields, wliile winter 

 barley matures 12 days before winter wheat, 20 days before spring oats. 23 days 

 before spring wheat, and 10 days before spring barley. The .short growing sea- 

 son renders the crop well adapted to high altitudes. 



Sixteen barley varieties are briefly described and the results of nursery and 

 field tests reported. The covered six-rowed bearded varieties proved more pro- 

 ductive than the naked six-rowed hooded varieties. 



Corn experiments in 1915, P. R. Fedorov {Bezmchuk. Sel.sk. Khoz. Opytn. 

 Sta. No. 75 {1916), pp. 6). — Experiments for the past two years show that the 

 local (Samara) varieties of corn yield the higher in dry seasons, mature 

 better, contain smaller percentages of water, and keep better than varieties 

 imported from warmer and more humid regions. The latter, however, give 

 higher yields in seasons with high humidity. 



Cotton experiments. 1916 {}fi.fsissippi Sta. Bui. 178 {1916), pp. S-1,0. figs. 

 S). — Suggestions for cotton culture in different parts of Mississippi are pre- 

 sentetl and the results of cotton experiments conducted at the Mississippi 

 Station and the Holly Springs and Delta substations reported as heretofore 

 (E. S. R., 34, p. 830).
