to organic forms for Honduras rice, but for late maturing varieties the differ- 

 ences were not great. 



The Mungo bean appeared to make a heavier growth of vine than any other 

 leguminous crop grown at the station. Garlic also seemed to do well on rice 

 soils. 



Suggestions for the use of fertilizers for tobacco and onions for 1916, 

 PI. D. Haskins (MassacJmsetts Sta. Circ. 60 (1916), pp. 4). — A brief popular 

 discussion of the use of fertilizers for tobacco and onions, suggesting for each 

 crop two fertilizer formulas and noting the value of the use of lime. 



Com in Montajia, A. Atkinson and M. L, Wilson {Montana Sta. Bui. 101 

 {1915), pp. 11-128, figs. 34). — This bulletin discusses the economic importance 

 of corn for Montana, reviews its history from its earliest culture by the 

 Indians down to the present day, presents notes on the classification and vari- 

 etal history of corn, describes a list of varieties adapted to certain regions of 

 the State, and points out the influence of the prevailing climatic conditions on 

 the production of the crop. 



The results of experiments conducted in 1913 and 1914 at Wibaux, where the 

 conditions of eastern Montana are fairly well represented, are reported in tables 

 and disemssed. Seven varieties of flint were found to have an average total leaf 

 area per plant of 1,868.6 sq. in., 2 varieties of late flint of 2,124.4, 3 varieties 

 of semident of 1,211, 6 varieties of early dent of 1,119.4, and 2 varieties of late 

 dent 2,101.6 and 4,678.2 sq. in., respectively. The average length of stalk was 

 47.6 in. in the early flint, 70.1 in. in the semident, and 62.6 in. in the early dent 

 varieties. No great variation was observed in the lengths of the first two or 

 three internodes of any of the groups. Of the stalks studied the early flint 

 varieties had from 6 to 9 internodes, the semident 8 to 11, and the early dent 

 9 to 10. In the early flint group the internodes were also much shorter than in 

 the other groups. The early flint, early dent, and semident groups had about 

 the same shelling percentage, which varied from 70 to 80 per cent. The propor- 

 tions of coarse and fine stalk, shelled corn, and cob were determined and are 

 reported in a table. The results of variety tests at Wibaux and at the Huntley 

 substation are also tabulated. 



Corn: Varieties, ear-row, and limiting factor tests, W. L. Hutchinson 

 {South Carolina Sta. Bui. 186 {1916), pp. 14). — The results of variety and ear- 

 to-row tests conducted at the station and the Pee Dee substation are tabulated. 

 Data secured in fertilizer and culture tests made at the Pee Dee substation in 

 1914 and 1915 are also reported. 



In 1913 the yields of 27 varieties at the station ranged from 28.3 to 49 bu. 

 per acre, Surecropper being the leading variety, and in 1915 the yields of 9 

 varieties ranged from 24.5 to 37.5 bu., Coker Williamson being the leading sort. 

 At the Pee Dee substation No. 181, among 20 varieties, stood first in yield in 

 1914 with 52.7 bu. per acre, and Chappell Garric, among 17 varieties in 1915, 

 with 52.1 bu. 



Ear-to-row tests at the station in 1913 indicated differences in yielding capacity 

 ranging from 27.7 to 77.7 bu. per acre, and in 1915 from 5.2 to 59.7 bu. At the 

 Pee Dee substation in a similar test in 1914, the lowest producing ear yielded 

 at the rate of 24.3 and the highest at the rate of 50.3 bu. per acre. 



The results secured in the fertilizer tests led to the conclusion that nitrogen 

 Is the element most needed under the conditions of the test. The culture tests 

 indicated that the method of planting corn in the water furrow between beds 

 and applying all fertilizers to the growing crop may have some merit. A plat 

 treated in this way yielded at the rate of 48 bu. per acre, or more than any one 

 of four other methods of culture under experiment.
