irno] FIELD CROPS. 735 



p. :v.\7) for the year prided June 30, 1918. The weather conditions are said 

 to have been unfavorable, and ail crops except potatoes showed yields below 

 the average. 



The maximum yields per acre secured of dlfferenl Held crops were as follows: 

 Oats 30.0 l)u., spring wheat 11.9 hu., barley 19.12 hu., winter rye 32.1 bu. f 

 winter wheat. 12.1 bu., potatoes 303.2 bu., rutabagas 15.6 tons, clover and 

 timothy meadows 1.L' tons, alfalfa 1.14 tons, oats and peas for hay 2.12 tons, 

 millet 1.02 tons, and Bromus iiicrmis 1.2 tons. 



An application of 10 tons of manure per acre resulted in an increase of 57.2 

 bu. of potatoes over flip untreated check.

 much more briefly than heretofore, describes the progress of work conducted 

 along the same general lines as previously noted (E. S. R., 38, p. 034), em- 

 bracing variety, fertilizer, rotation, and cultural tests with wheat, oats, barley, 

 rye, field peas, buckwheat, corn for silage, turnips, mangels, carrots, sugar 

 beets, flax, potatoes, alfalfa, vetches, clovers, grasses and tobacco; plant breed- 

 ing work with alfalfa, red clover, grasses, and root crops; and observations on 

 the effect ujkmi the yield of mangels of the use of seed obtained from different 

 sources. It is stated ttiat the results of the various lines of investigation will 

 be dealt with in more detail as the experimental work is completed. 



Spring small grains in Indiana, A. T. Wiancko and C. O. Cromer {Indiana 

 Sta. Bui. 225 (1V19), pp. 3-20, figs. J,).— Based on results obtained in variety 

 tests with spring-sown oats, barley, and wheat, and on observations of spring 

 rye and emnier it is stated that the growing of spring small grain can not be 

 recommended under normal seasonal conditions except in the northern portion 

 of the State, where profitable production is dependent upon early seeding, good 

 soil and cultural conditions, cool weather, careful selection of varieties, and 

 proper grading of seed. No important advantage was noted from the use of im- 

 ported seed. 



Oats are said to comprise about 99 per cent of the total area devoted to 

 spring-sown small-grain crops in Indiana. Medium maturing varieties, in- 

 cluding Great Dakota, Rig Four, Silver Mine, White Bedford, and Sehance, have 

 given the best results, while Daubeney and Sixty Day are regarded as the best 

 early sorts. The necessity for seed treatment for loose smut is emphasized and 

 directions given for both the wet and the dry methods ©f formaldehyde treat- 

 ment. 



It is suggested that the production of spring barley might profitably be in- 

 creased on mellow soils in northern Indiana. Silver King, Canadian No. 21, 

 and Hannchen have proved best, with Success Beardless the best early variety. 



Marquis and Regenerated Red Fife are said to be the most promising 

 spring-wheat varieties, although the crop is not deemed comparable to oats, 

 barley, winter wheat, or winter rye. 



The average yields of spring wheat, spring barley, and oats for the 9 years, 

 1010-1918, of spring emnier for 5 years, and of spring rye for 3 years amounted 

 to 13.7, 28.7, 52.6, 23, and 29.1 bu. per acre, respectively, as compared with 29.2 

 bu. for winter wheat and 3S.7 bu. for winter rye for the 9-year period. 



Farm practices in gTain farming in North Dakota, C. M. Dennis and R. E. 

 Wiixard (V. S. Dcpt. Agr. Bui. 757 (1919), pp. 35, figs. 17).— Based on data 

 secured in cooperation with the North Dakota Agricultural College from more 

 than 350 records of grain production in 34 counties in the State for 1912, 1913,
