Kafir corn with 14.52 tons, and Dwarf Kafir with 14.27 tons were first in tests 

 lor silage production in 1914. In ratc-of-seeding tests with Dwarf milo and 

 r>Iackhull Kafir, the highest yields, amounting to 68.21 and 56.51 bu. per acre, 

 respectively, were obtained with the plants 11.2 in. and 14.3 in. apart in 3-ft 

 rows. Milo maize and Kafir corn planted in S-ft. rows produced 50.53 and 

 46.28 bu. per acre, respectively, as compared with yields of 46.45 and 30 bu. 

 when planted in 6-ft. rows. Date-of-planting tests with milo maize showed 

 yields j-anging from 51.59 bu. for plantings made J\lay 7 to 21.44 bu. for those 

 made July 15. Variety tests with saccharin sorghums resulted in maximum 

 yields of 6.068 and 6.051 tons of cured roughage per acre for Orange and Sumac, 

 respectively. Further tests of the same varieties for silage showed yields of 

 green forage amounting to 15.79 tons per aci'e for Sumac and 14.46 tons for 

 Orange. 



Cotton variety tests conducted during 1912 and 1914 showed average yields 

 of seed cotton ranging from 703.4 lbs. per acre for long staple to 1,003.57 for 

 Cleveland Big Boll. Based on factors other than yield. Lone Star and Mebane 

 Triumph are deemed best for local conditions, pending furtlier trial. Half- 

 and-Half is regarded as decidedly inferior to these varieties. The highest 

 yield of lint cotton, 573.69 lbs. per acre, obtained in rate-of-thinning tests was 

 secured with the plants thinned to 16 in. apart in 36-in. rows. 



June corn and yellow dry -land corn grown during 1914, an unusually favor- 

 able year for corn in this region, gave yields of 29.2 and 7.9 bu. per acre, re- 

 spectively. Variety tests with wheat, barley, emmer, rye, and oats are held to 

 indicate that the winters are usually too long and dry for the successful pro- 

 duction of small grains. Turkey, Kharkof, and Crimean winter wheats and 

 Tennessee winter barley are regarded as showing some promise. 



New Era and Early Buff cowpeas, with yields amounting to 12.22 and 12.6 

 bu. of seed per acre, respectively, are deemed best for this locality. 



Date-of -plowing tests for seed-bed preparation are described and are held to 

 indicate the need of early seed-bed preparation. Cotton yields varied from 

 753.84 lbs. of lint cotton per acre for November 21 (1913) plowing to 593.29 

 lbs. for April 2 (1914) plowing; yields of Sumac sorghum for hay varied from 

 7.1 tons for February 2 plowing to 6.02 tons for April 2 plowing, and for silage 

 from 19.69 to 17.25 tons per acre, respectively ; and yields of cowpeas fi-om 

 10.41 bu. of seed per acre for the February 2 plowing to 7.5 bu. for tJie April 2 

 plowing. Various methods of seed-bed preparation for milo maize wei'e tested, 

 the highest grain yield, 73.9 bu. per acre, being obtained from fall-listed plats, 

 and the highest yield of green forage, 16,300 lbs., from plats fall-plowed 6 in. 

 deep. Spring listing, as compared with January plowing, 3, 6, and 9 in. deep, 

 for cotton resulted in yields of lint cotton amounting to 589.21 lbs. per acre for 

 the former method and a maximum yield of 548.15 lbs. for January plowing 

 3 in. deep. Fall plowing as compared with fall listing for cotton gave average 

 yields amounting to 737.51 and 734.57 lbs. of seed cotton per acre, respectively. 



Applications of 2 tons of manure per acre to feterita gave yields of grain 

 amounting to 39.73 bu., and of dry forage of 14,196 lbs. per acre, as compared 

 with yields of 35.09 bu. of grain and 13,512 lbs. of forage, respectively, from 

 unmanured plats.

 results otf variety and cultural tests with grain and forage sorghums, corn,
