4 bu. less than that which was similarly treated except that it was subpacked 

 immediately after plowing. Three other plats similarly treated but plowed 

 only 4 in. deep produced much smaller yields. 



Other work reported includes tests of wheat varieties and hybrids and alfalfa 

 varieties. 



Forage experiments in Southern District, H. Ross (Agr. Gaz. 2V. 8. Wales, 

 22 {.1911), \So. 10, pp. S76-S78). — In a test of the forage-producing power of 

 different plants Early Learning corn was excelled only by Early Amber sorghum. 



North Coast experiments, G. Marks (Agr. Gaz. N. 8. Wales, 22 {1911), No.

 forage yields of different varieties of corn, sorghum, millet, and cowi>eas are 

 reported.

 oats, barley, and peas, and of tests of fertilizer mixtures and of mixed forage 

 crops.

Alfalfa, L. R. Waldron (North Dakota Sta. Bui. 95, pp. 355-42Jf, figs. 15).— 

 This bulletin consists of two parts. 



I. Practical information for alfalfa grotoers. — This is a digest of information 

 relating to alfalfa production and utilization in North Dakota. The results 

 reported in a number of experiment station and other publications already 

 noted are briefly summarized. A bibliography of 12 titles is given. 



II. Alfalfa studies made at Dickinson ; particularly drought resistance, water 

 requirements and seed production. — This paper reports the results of experi- 

 ments conducted for the purpose of determining what constitutes a proper 

 stand of alfalfa under the climatic conditions of North Dakota. 



Seeding at the rate of 10 lbs. per acre apparently gave too thick a stand, 

 while stands much thinner than are usually regarded as normal gave very 

 satisfactory yields. Plants from thin stands had much better developed 

 root systems than those grown in thick stands. A table states the hay yields 

 secured during 1909-10 in a test of 18 varieties or strains of alfalfa, but the 

 author regards the data as " of little value in showing the comparative yields 

 of the various strains " because variations in stand, root development, and 

 inoculation were great enough to offset difference in yield. 



Studies in drought resistance may be summarized by the following table : 



Alfalfa yields and quality of hay from definite distance transplant plats, 1910. 



The roots of the plants from these plats had a better development than the 

 roots of the plants from the field. Photogi'aphs show that some at least of 

 these transplanted plats had many roots acting as tap-roots but that they were 

 rather small and did not go down to a great depth.
