FIELD CROPS. 527 



Field experiments with corn, A. A. Mills ( Utah Sta. Rpt 1893, 

 pp. 336-3-19).— Theaa consisted of tests of varieties, of tliick aucl tbia 

 planting, and of detasseling. Of the varieties grown 3 years tlie com- 

 mon white flint of the locality gave the largest average yield. Thick 

 and thin planting gave almost identical results. Every alternate row 

 of corn was detasseled. These rows gave a smaller yield than the 

 alternate rows not detasseled. 



Methods of cultivating corn, J. W. Sanborn ( Utah Sta. Rpt. 1893, 

 2)p. 131-139, 150-157). — Eight plats were cultivated at different depths. 

 The results seem to favor shallow culture. Temperatures and per- 

 centages of moisture for the soil of the different plats are tabulated. 

 "The plats shallow tilled had a lower temperature than those deep 

 tilled. . . . More water was retained in the soil on the plats deep tilled. 

 . . . This gain, however, was confined to the lower areas from 4 to 

 8 in. deep." 



Exi)eriments bearing on drilling and checking corn gave results not 

 entirely conclusive. Determinations of soil temperature and of moisture 

 in the different plats are tabulated. "Corn that was tilled flat gave 

 the warmest soil between the rows, and as it gave rather the largest 

 crop, it is not improbable that there is a connection between the two 

 facts." 



Why pull your corn fodder? F. E. Emery {North Carolina Sta. 

 Bui. 104, pp. 263,264). — In 1893 the amount of dry matter in different 

 parts of the corn plant was determined at the time when the ears of 

 corn were "from thick milk stage to nearly ripe." Of the total dry 

 matter produced on 1 acre the ears contained at that time 19.85 per 

 cent, the husks 6.8 L per cent, the leaves 20.60 per cent, and the stalk 

 52.68 per cent. Of the total dry matter on 1 acre the ears contained 

 1,503.88 lbs., the husks 515.59 lbs., the leaves 1,565.08 lbs., and the 

 stalks 3,990.25 lbs. The author recommends the cutting and shocking 

 of corn so as to secure the greatest amount of forage. 



Field experiments with cotton, 11. J. Redding [Georgia Sta. Bui. 

 24, pp. 109-123). 



Synopsis. — The experiments are classified as follows: (1) Variety test, in which 

 Duucaii gave the largest yield ; (2) distance experiments ; (3) a general fertilizer 

 test, the best complete fertilizer being 468 lbs. superphosphate, 36.4 lbs. muriate 

 of potash, and 130 lbs. nitrate of soda per acre; and (4) an experiment in 

 plowing under jiea vines at different stages of growth as a green manure for 

 cotton, in which results were favorable to mature pea vines. 



Test of varieties (pp. 109-114). — Seventeen varieties of cotton were 

 tested. The yield at each picking, number of bolls to a pound of seed 

 cotton, number of seeds in 1 lb., total yield of lint and seed, per cent 

 of lint, and value of lint and seed are tabulated. Duncan gave the 

 largest yield of seed cotton (2,285 lbs. per acre) and Dearing Small Seed 

 the largest percentage of lint (36.3). The earliest varieties were King 

 and Hawkins J those having largest bolls, Jones Improved and Truitt
