FIELD CROPS. 139 



Shaw Improved and Higgin Improved are the only varieties tested for 

 six years in succession and are considered as being - uniform and per- 

 sistent in yield. 



A general fertilizer test proved unsatisfactory. It is stated that 

 previous tests have indicated that, in a commercial fertilizer for corn on 

 an average soil of middle Georgia, available phosphoric acid, potash, 

 and nitrogen should be in the relative proportion to each other of 

 7: 1.3: 3.4, which would be secured in a mixture of 1,000 lbs. acid phos- 

 phate, 50 lbs. muriate of potash, or 200 lbs. of kainit, and 1,000 lbs. of 

 cotton-seed meal. 



The results of the distance experiments confirm the general con- 

 clusions drawn from previous experiments that "the more nearly the 

 area of soil appropriated to each individual plant approaches the form 

 of a square the greater will be the yield." Spacing the plants at differ- 

 ent distances in rows of uniform width resulted in better yields from 

 corn planted 4 by 3, with one plant in the hill, than when planted 4 by 

 2 or 4 by 4. 



An experiment with subsoiled and unsubsoiled land for corn indicated 

 that " subsoiliug of the land covered by the experiment was not profit- 

 able." Subsoiling produced no appreciable effect. 



Abstracts from former bulletins and the condensed reports on variety 

 tests of cotton, the results of which are soon to appear in bulletin form, 

 are given. 



Fertilizer, culture, and variety experiments on cotton, B. J. 



Bedding {Georgia Sta. Bid. 39, pp. 107-135, pi. 1). — These experiments 

 are a continuation of work formerly reported in Bulletin 35 of the sta- 

 tion (E. S. B., 9, p. 127). The results of the experiments and the 

 meteorological data for the season are given in tables. Fertilizer for- 

 mulas for various crops, with directions for mixing and applying them, 

 are appended. 



Among 2L varieties of upland cotton, Nancy Hanks, Texas Bur, 

 Jackson "Limbless," and Culpepper Improved ranked highest in the 

 value of lint and seed, in the order mentioned. Nancy Hanks, yielding 

 1,473 lbs. of seed cotton per acre, stood first in the yield of seed and 

 lint, matured earlier and proved most profitable. Strickland Improved 

 produced the largest bolls and Texas Oak and Jackson "Limbless" 

 yielded the largest percentage of lint (37.1 per cent). King Improved, 

 a small boiled, small seeded, early variety, and Strickland Improved, 

 a large boiled, large seeded, late variety, yielded on an average of 7 

 plats each, 1,134 lbs. and 1,349 lbs. of seed cotton per acre respectively. 

 A number of varieties, including Jackson "Limbless," are described in 

 detail, and the address of the dealers in different varieties of cotton 

 seed are given. 



Distance experiments have been made for seven consecutive years. 

 Plants were placed 1, 2, 3, and 4 ft. apart in rows 4 ft. apart. This 

 year the best yield was obtained with a distance of 3 ft. between plants,
