32 EXPERIMENT STATION RECOBD. [Vol.38 



Corn sown to cowpeas in 1913 after the corn had approached maturity showed 

 no reduction in yield when compared with corn grown alone. Cowpeas sown 

 in corn during the early period of growth in 1912 apparently caused a reduc- 

 tion in the yield of corn of nearly 50 per cent. 



In variety tests with oats for hay in 1912, Texas Red Rust Proof, Hundred 

 Bushel, Appier, and Tennessee Turf gave yields of 9,550, 8,830, 8,430, and 6,130 

 lbs. per acre, respectively. Further tests with Texas Red Rust Proof in ro- 

 tation for hay gave yields of 4,960 and 2,220 lbs. per acre for 1913 and 1914, 

 respectively. 



CJowpea rate-of-seeding tests conducted in 1918 and 1914 gave average yields 

 of cured hay of 2,375, 2,316, and 2,866 lbs. per acre, respectively, for 30-, 60-, 

 and 80-lb. rates sown broadcast. 



The average yields secured in tests with 6 varieties of peanuts for 1912 and 

 1913 varied from 14.39 bu. per acre for Tennessee Red to 31.52 bu. for Spanish. 

 A comparison of seeding peanuts in rows 18 in. apart with seedings made in 

 rows 36 in. apart for the same period and employing all the varieties used In the 

 tests noted above gave an average yield of 20.24 bu. per acre for all seedings in 

 3-ft. rows and 23.38 bu. for all seedings in 18-in. rows. 



Common and Turkestan varieties of alfalfa grown in 1911 gave total yields 

 of 2,450 and 2,000 lbs. of cured hay per acre, respectively. Further tests with 

 alfalfa have proved unsuccessful. 



Six varieties of bur clover grown on the substation since 1912 are reported as 

 giving very satisfactory results. 



Of the standard grain sorghum varieties grown in 1913 and 1914 BlackhuU 

 Kafir was first in yield of cured forage and of grain, with an average production 

 of 7,282 lbs. of forage, and 23.35 lbs. of seed per acre. Rate-of-seeding tests 

 with grain sorghums conducted from 1912 to 1914, inclusive, and to be reported 

 later in detail indicate that the best results will be obtained with plantings 

 from 6 to 8 in. apart in the row. 



Tests are reported for 1912 with Amber and Sumac sorghums for hay planted 

 in 3-ft. rows with the plants spaced in the rows from 0.25 to 6 in. apart. The 

 yields varied from 1.45 to 2.8 tons for Amber and from 6.15 to 8.7 tons for 

 Sumac for the 6- and 0.25-in. spacings, respectively. Supplemental tests con- 

 ducted in 1912 and 1913, in which the two varieties were planted in close drills 

 at 25-, 50-, and 100-lb. rates, gave average yields of 3.9, 4.47, and 4.02 tons of 

 cured hay per acre, respectively, for Amber and 8, 8.7, and 7.98 tons for Sumac. 



Sudan grass sown in 3-ft. and 18-in. rows, and broadcasted in 1913 gave yields 

 of hay amounting to 11,240, 10,420, and 9,400 lbs. per acre, respectively, and of 

 seed amounting to 400, 360, and 380 lbs., respectively. Rates of seeding Sudan 

 grass equivalent to 15, 20, 30, and 40 lbs. per acre gave total yields averaging 

 from 4.4 to 4.55 tons per acre. Sudan grass and cowpea mixtures sown for 

 hay gave unsatisfactory results. 



Experiments in seed-bed preparation conducted in 1913 and 1914 indicated 

 that either listing or plowing the land 6 or 8 in. deep furnished the most satis- 

 factory seed bed for corn, cotton, and Kafir corn. 



In potato variety tests Bliss Triumph, Early Rose, Irish Cobbler, and Gold 

 Coin have given the best results, the early varieties being deemed superior for 

 this region. In fertilizer tests with potatoes the highest average yield, amount- 

 ing to 89.83 bu. per acre, was obtained with an application of 200 lbs. each of 

 cottonseed meal and acid phosphate. The average for all untreated check plats 

 was 60.95 bu. The lowest yield, 52.24 bu. per acre, was obtained from a 400-lb. 

 application of sulphate of potash. From the results obtained it is concluded 

 that acid phosphate combined with some nitrogenous fertilizer will give the 

 best results on these soils.
