230 EXPERIMENT STATION RECORD. 



132.54 and 116.42 bu., respectively. Rural New Yorker is noted as more ex- 

 tensively grown thi'oughout the State than any other variety. 



The following statement is made in regard to the results of selecting the 

 best and the poorest hills under test : " In making selections those hills which 

 had an average number of well-formed, medium-sized tubers for the variety 

 were selected. These hills could, as a rule, be chosen by the appearance of the 

 vines, though this was not always true. This method of seed selection would 

 prove profitable to the grower if he could set aside a small seed plat and select 

 his next year's seed from it. The results are striking in that the yield was 

 increased 50 bu. by taking the best and poorest seed only one year. By taking 

 the best seed from each of these lots of seed the strain with quality behind it 

 still outyielded the poorest strain [the following year] by nearly 50 bu." 



The data presented in regard to the influence of planting date upon yield 

 indicate that the soil temperature as affected by weather is more influential 

 than is the date. The inconclusive results obtained from a three-year experi- 

 ment that indicates about the best time for planting has been that following 

 the corn planting, or from May 10 to May 25. 



The effect of potato scab treatment on seed vitality. — Better methods of 

 potato production for Iowa, T. J. Maney and L. Greene {Iowa St a. Buls. 148 

 and 149, popular ed. (1914), pp. 8). — This is a popular edition of Bulletins 148 

 (abstracted on page 240) and 149, abstracted above. 



Xenia (?) in rice, H. O. Jacobson (.Philippine Agr. Rev. [English Ed.], 7 

 (1914), A'O. 9, p. 361). — This notes the appearance of two pinkish colored ker- 

 nels of rice appearing in a head of variety No. 73, which is a white variety. 

 " These two kernels were planted separately and crops therefrom matured. 

 One kernel («) produced white kernels only, while the second kernel (&) pro- 

 duced nothing but red-cuticled kernels. Each lot was again planted separately 

 and the (a) lot when harvested contained 6 per cent of red-cuticled kernels. 

 The (h) lot produced 24 per cent of white kernels, the remainder being red. 

 In no case were red and white kernels found in the same head, of course. It 

 Is plainly evident that the (&) kernel was a hybrid produced through cross- 

 fertilization by the pollen from some near-by red-cuticled variety." 



Head-to-the-row test with rice, H. O. Jacobson (Philippine Agr. Rev. 

 [English Ed.}, 7 (1914), ^o. 9, pp. 346-351, pis. 2).— This article describes a 

 method of head-to-the-row selection, and gives some results that show great 

 possibilities in rice improvement. Observations are noted as being taken and 

 recorded on 27 variable characteristics of individuals within each variety under 

 trial, that of yield being most marked and important. The yield of 100 plants, 

 the progeny of single heads, was at the rate of from 375 to 6,625 kg. of rough 

 rice per hectare, all within the same variety. 



The transplanting of rice, P. and G. Gbegotti (Gior. Risicolt., 4 (1914), 

 No. 20, pp. 301-307, figs. 3). — This article gives data of work done at Valencia, 

 Spain, showing the advantage secured both in yield and in actual profits by 

 the practice of transplanting rice in the field. 



Drilling-fertilizer experiments with, sugar beets in Hungary in 1912, J. 

 Gyarfas (Osterr. Ungar. Ztschr. Zuckerindits. u. Landw., 42 (1913), No. 6, pp. 

 883-893, pi. 1). — The results given show larger yields whei-e the fertilizer is 

 applied in drills at seeding time than when broadcasted, in some cases even 

 when only one-half the amount was drilled that was applied broadcast. 



Can sodium, wliolly or partially, replace potassium as a fertilizer for 

 sugar beets? Krxjger (Ztschr. Ver. Deut. Zuckcrindiis., No. 703, II (1914). PP- 

 694-702). — This article gives the results of a pot experiment in which potash 

 in varying quantities was given and sodium was supplied in quantities to equal 

 the deficiencies in potash that would be required to produce a maximum yield
