In another comparison " of varj-ing amounts of cotton-seed meal, acid phos- 

 phate, and liaiuit, other elements being normal, with no fertilizer," the highest 

 yield followed an application of 600 lbs. cotton-seed meal, 150 lbs. acid phos- 

 phate, and 50 lbs. kainit, but the highest net profit followed the use of 200 lbs. 

 cotton-seed meal, 150 lbs. acid phosphate, and 50 lbs. kainit. On another plat, 

 however, this latter mixture was applied at an apparent financial loss. In a 

 test of different nitrogen sources and of applications made entirely at planting 

 time, or half at planting and half on July 20, 2,4S3 lbs. of seed cotton per acre 

 was obtained after fertilization with 80 lbs. of nitrate of soda on each of these 

 two dates as compared with 2,133 lbs. when 160 lbs. were applied at planting 

 time. An application of 400 lbs. of cotton-seed meal was followed by a lower 

 yield than that secured on the check plat. An application of 200 lbs. of cotton- 

 seed meal at planting time and 80 lbs. of nitrate of soda, July 20, was followed 

 by a yield of 2,216 lbs. of seed cotton per acre. This application ranked second 

 in value of increased yield over the cost of the fertilizer used, the divided 

 application of nitrate of soda being first in this respect as well as in yield. 

 Spacing and variety tests are noted on page 434. 



Better yields of peanuts wei*e obtained from plants planted during the first 

 week in June than on other dates, and from plantings 16 in. apart in rows 3 ft. 

 apart than at other distances. No increase in yield followed the use of fer- 

 tilizers for peanuts on a fertile sandy loam. 



Brief progress reports are also given on tests with corn, alfalfa, oats, and 

 soy beans, and with wheat and vetch followed by soy beans. 



[Cabbage and potatoes at the New Mexico Station], F. Garcia (New Mexico 

 Sta. Rpt. 1911, VP- 33-37, fig. 1). — Four different plantings of cabbage were 

 made at intervals of about 2 weeks, beginning March 2. The earliest planting 

 gave the best results on the whole, but the second planting did almost as well, 

 while the last planting, made April 17, was too late to do much good. 



Practically no yields of potatoes were secured in either plat or pot tests. 

 The plants in pots in a more humid section of the greenhouse grew considerably 

 taller than those in the drier portion or those in the field, but the size of the 

 vines did not seem to affect materially the size or yield of tubers. 



Results of cooperative experimental work for 1911, F. G. Tabbox, Jr. 

 (South Carolina Sta. Circ. 5, pp. 3-19). — The results of cooperative experiments 

 the station is conducting with farmers in the State are briefly noted. In the 

 spring of 1911, the station distributed among the farmers of the State for this 

 work about 140 bu. of cotton seed, about 60 bu. of corn of the Marlboro Pro- 

 lific, Boone County White, and Coker Williamson varieties, and a quantity of 

 seed of winter cover crops, including vetch, clover, and rye. 



Tables of field crops, J. N. Harper (South Carolina Sta. Circ. 2, pp. 18). — 

 Popular information regarding the culture of field crops adapted to the South 

 is presented in tabular form. 



Competition in cereals, E. G. Montgomery (?\''cl)raska Sta. Bui. 127, pp. 3-22, 

 figs. 7).— This bulletin states the results of tests in which wheat and oats were 

 planted i, ^, 1, 1^, and 2 in. apart in rows to determine the percentage of plants 

 which survive competition of these different degrees of intensity. The competi- 

 tion of well developed with poorly developed kernels and of one variety with 

 another was also tested. Data are presented in 19 tables from which the 

 author concludes that the percentage of plants which survive until harvest 

 decreases as the rate of planting is increased. In these tests the total decrease 

 amounted to 34 i3er cent and the relative survival of the thinnest and thickest 

 stands averaged 75 and 56 per cent, respectively. 



When plump and small or poorly developed seed were alternated in the same 

 row, the decrease in number of plants was 28 and 38 per cent, respectively, but
