spectlvely, while soedings of 6:1 and 4:1 mixtures of cowpeas and sorghums 

 resulted in average yields of 4,057 and 4,524 lbs. per acre, respectively. Rate- 

 of-seeding tests in close drills with a 4 : 1 mixture resulted in average y^lds 

 of 3,721 lbs. of cured forage per acre for a 60-lb. rate and 3,609 lbs. for a 

 30-lb. rate. For the two years 1913 and 1914, the maximum yield, 4,207 lbs. 

 was obtained from a 60-lb. rate. Tests of various planting rates of a 4 : 1 mix- 

 ture sown in 36-in. rows showed a maximum yield of 7,186 lbs. of forage per 

 acre for a 19-lb. rate of seeding. A mixture of 6 parts cowpeas to 1 part Sudan 

 grass seeded in 4, 6, and 8 pk. rates produced 3,300, 2,950, and 3,350 lbs. of 

 cured hay per acre, respectively. Seeded alone at a 12- and 30-lb. rate, Sudan 

 grass gave respective yields of 1,764 and 2,887 lbs. of hay per acre, but when 

 sown with 60 lbs. of cowpeas it produced only 1,056 and 2,039 lbs. of hay per 

 acre, respectively. It is concluded that a mixed cropping system is inadvisable, 

 it being deemed more profitable to produce the crops separately and mix them 

 when fed. 



Burnett and Mebane Triumph, with respective yields of seed cotton of 1,199.5 

 and 980.4 lbs. per acre, were highest in cotton variety tests. In rate-of-thinning 

 tests with two varieties during 1912 to 1914, inclusive, and with 3 varieties 

 during 1913 and 1914, the highest yields were obtained from spacings of from 



11 to 12 in. in 3-ft. rows, amounting to 883.19 and 1,399.53 lbs. of seed cotton 

 per acre, respectively. Similar tests with 3 varieties in 1914 showed a maxi- 

 mum yield of 2,287 lbs. of seed cotton per acre for a spacing of 6 to 7 in., 

 together with the highest number of bolls per pound of seed cotton, 78.4. The 

 results, on the whole, are deemed rather inconclusive, although a stand of 



12 in. apart in 3~ft. rows is regarded as satisfactory in this locality. 



The highest yielding cowpea varieties were Khotan, with an average yield of 

 16.85 bu. per acre, and Old Bokhara, with 16.04 bu. Tests of different seeding 

 rates of cowpeas sown in close drills for forage indicated that a rate of 6 to 

 7 pk. per acre was best for maximum production. Seeded in rows for forage, 

 a rate from 18 to 20 lbs. gave the highest yield, 2,574 lbs. per acre. Aver- 

 age results for all methods of planting for the period of 1912 to 1914, inclusive, 

 showed a yield of 2,949 lbs. of forage per acre for drill plantings and 2,472 lbs. 

 for row plantings. 



Peanuts are said to be successfully grown, as a rule, in this region, the Span- 

 ish variety having produced an average yield of 32.15 bu. per acre for a 3-year 

 period. 



Average yields of Tepary beans for 1912 and 1914 amounted to 17.67 bu. per 

 acre. Navy beans and Extra Early I^ima Ijeans grown in 1914 gave yields of 

 5.6 and 16.73 bu. per acre, respectively. 



Dwarf, Dwarf Standard, and Standard broom corn produced yields of cured, 

 clean, strij)ped brush in 1912 of 198, 251, and 257 lbs. per acre, respectively, 

 and of cured unstripped brush in 1913 of 1,622 and 2,355 lbs., respectively, 

 for the first two varieties. 



Cereal crops are regarded as rathor uncertain except in seasons of abundant 

 moistui'e supply, although rye, wheat, and emmer are said to make excellent 

 winter pasture. Maximum yields in variety tests with small grains were 

 obtained as follows : Burger, Malakof, Turkey, and Crimean winter wheats 

 with 5.8, 5.4, 5.2, and 5 bu. per acre, respectively ; Burt and Sixty-Day oats 

 with 11.5 and 10.4 bu. per acre, respectively ; Odessa and Caucasian barley 

 with 10.25 and 9.65 bu. per acre, respectively ; and rye with 10.8 bu. per acre. 



Applications of 2 tons of manure per acre to feterita resulted in yields of 

 51.4 bu. for the manured plats and 49 bu. for the unmanured. Similar appli- 

 cations to cotton showed an average yield of seed cotton of 1,593.1 lbs. per 

 acre as comftared with 1,524.2 lbs. for the unmanured plats.
