232 EXPERIMENT STATION RECORD. 



hominy. The ears average 19 cm. (7.4 in.) long and 5 cm. thick at the center 

 and have 16 rows of grain. 



Distance to plant maize, A. H. Rosenbf.ld (Rev. Indus, y Agr. Tiwumdn, 

 3 {1912), No. 6, pp. 231-235). — In this experiment plants spaced 125 cm. (about 

 49 in.) in rows 30 and 75 cm. apart gave better results than plants spaced 40, 

 75, or 100 cm. in rows spaced 30, 75, and 100 cm. apart. The check-row 

 system, with hills of 3 or 4 plants about 1 meter apart, yielded about 30 per 

 cent better than the row system. 



Fertilizing maize (Prog. Agr. y Pecuario, 19 (1913), No. 818, pp. 258-260). — 

 Results of the use of commercial fertilizers for com in 3 different fields are 

 given, in which increased yields were obtained at a profit by the use of the 

 fertilizer. 



The effect of water level on the yield of cotton (Agr. Jour. Egypt, 2 (1912), 

 No. 1, pp. 37, 38, fig. 1). — The results of an experiment, in which the water 

 level ranged from 0.8 to 2.2 meters (from 31 to 86 in.) below the ground surface, 

 showed increased yields as the depth of water level increased. 



A report on the production of new cottons, W. L. Balls (Agr. Jour. Egypt, 

 2 (1912), No. 2, pp. 66-77, pis. 4)- — This article gives the methods employed in 

 crossing and the preventing of crossing, and discusses the time required for 

 propagation, simple propagation of seed, a list of approximate constants, and 

 possible rates of propagation. In some of the new cottons produced the mean 

 maximum lint strength ranged from 27.7 to 33.5 mm. 



Experiments in cotton cultivation at the experiment station of Karaiasi, 

 Transcaucasia, V. Dmitrievski (Ahs. in Internat. Inst. Agr. [Rome], Bui. Bur. 

 Agr. Intel, and Plant Diseases, 3 (1912), No. 11, pp. 2425, 2426).— This experi- 

 ment was based upon the color of the cotton seeds, and as a rule the green 

 seeds gave a more abundant and finer fiber than those of other colors. The 

 results of planting seeds picked at different dates showed very little difference 

 in yield or date of maturity, although the slight difference was in favor of the 

 later picking. 



Annual report of the g-overnment cotton station at Myombo (Pflanzer, 8 

 (1912), No. 6, pp. 323-334). — In a test of 6 varieties the yields of ginned cotton 

 ranged from 52.6 to 213.2 kg. per hectare (46.8 to 189.7 lbs. per acre). Seed 

 planted January 22 produced 196.4 kg. ; that on February 3, 92.4 kg. ; that on 

 February 20. 34.8 kg. ; and that on March 4, 10 kg. ginned cotton per hectare. 

 When plants were thinned to 2 in a hill placed 100 by SO cm. apart, the yields 

 of ginned cotton were, on 2 plats, 129.2 and 138.4 kg. per hectare, respectively, 

 and when thinned to only 1 plant per hill on 2 plats 53.5 and 42 kg. per hectare, 

 respectively. Irrigation did not increase the yields. 



Cowpeas, R. E. Blouin (Rev. Indus, y Agr. Tucumdn, 3 (1913), No. 8, pp. 

 355-359). — Numerous varieties are described and methods of production, alone 

 and in combination with maize and with cane, are discussed. 



Don experiment field, I. Kolesnikov (Ahs. in Zhur. Opytn. Agron. (Russ. 

 Jour. Expt. Landw.), 13 (1912), No. 3, pp. 44S, W)- — The apparent increase in 

 the yield of flaxseed for 9 years due to deeper plowing amounted to 14 per cent. 



Fertilizers in the production of hemp, Palladius (Prog. Agr. y Pecuario, 

 18 (1912), No. 770, pp. 261-264, figs. 4). — In these experiments it was found 

 that the addition of potash to other fertilizers apparently increased the yield 

 of fiber, in some cases more than 100 per cent. The yields ranged from 1,850 

 to 2,530 kg. per hectare (1,646 to 2,251 lbs. per acre). 



Studies on hemp culture in Italy, W. F. Bruck (Tropenpfianzer, 15 (1911), 

 Nos. 3, pp. 129-141; 4, pp. 187-202; 5, pp. 244-^64, figs. 6).— This article dis- 

 cusses the importance of the hemp industry in Italy, gives a brief historical 

 review, including the development of hemp culture in different parts of the
