out breaking: the soil, stood second in yield, falling:: very little below the plowed 

 or cultivated plats. In a test of planting kafir and cowpeas in alternate rows 

 the results in 1918 were in favor of 42-in. rows of katir without cowpeas in both 

 yield of forage and grain. The average results of different rates of planting 

 kafir in the row indicated that 8 to 12 in. between plants gave the highest yields. 



Sudan grass was sown on four different dates from about the middle of April 

 to the last of May. The seeding made April 12 gave the highest yield, and 

 Iiroadcasting at the rate of 40 lbs. to the acre proved the most satisfactory 

 method of seeding. A comparison of different dates of seeding sw^eet clover 

 resulted this year in good stands on all plats sown in March and April. Sur- 

 face seeding produced a thicker stand than where the ordinary depth of seeding 

 was followed. The u.se of oats as a nurse crop for the March seeding did not 

 produce a favorable effect. 



[Field crops work at the Nacogdoches substation], G. T. McNess (Texas 

 Sta. Bui. 251, (1919), pp. 6-8, 10-21, 22, figs. 6).— Acid phosphate, cottonseed 

 meal, and potash were used singly and in combination as fertilizers for to- 

 bacco and corn. In the tobacco experiments 1,200 lbs. of cottonseed meal and 

 400 lbs. of acid phosphate per acre, the only application showing a marked in- 

 crease over the use of no fertilizers, gave an increase of .$23.47 in the net re- 

 turn per acre. The plats receiving cottonseed meal produced the best quality 

 of leaf in the test. 



In the fertilizer tests with corn an application of 200 lbs. of cottonseed meal 

 and 100 lbs. of acid phosphate per acre was found most profitable, especially 

 on soils well provided with organic matter. In 1918 varieties of corn which 

 had shown good results in previous tests were planted March 15, April 1, and 

 April 17 for further comparison. The five leading varieties, in diminishing 

 order of yield, were Surcropper, Brazos White, Chisholm, Oklahoma White 

 Wonder, and Blount Prolific. Planting at the rates of 3,630 stalks and 4,840 

 stalks per acre gave in general the best results in a test on the rate of planting. 

 Corn planted in rows either 3 or 6 ft. apart gave practically the same average 

 yield. Planting cowpeas between the rows before the corn was 3 ft. high 

 showed a tendency to reduce the yield of corn. 



The results of a 4-year test with Mebane cotton planted on upland in rows 3 

 ft. apart indicated that 2 plants to the hill, and the hills 21 in. apart in the 

 drill, is likely to give the highest yield of seed cotton. In a 3-year variety 

 test Roundnose ranked first in the average yield of seed cotton per acre, with 

 Ilowden, producing a better staple, standing second. Among varieties not 

 tested throughout the 3 years Chisholm ranked first in ginning percentage with 

 46.51 per cent of lint, being followed by Improved Champion with 45.8 per 

 cent, Mexican Big Boll with 42.85 per cent, and Kasch with 42.22 per cent. A 

 comparison of varieties with regard to length of lint showed that Snowflake 

 ranked first with 1/g in., Express second with Its in., and Lone Star, Trice, 

 and Acala third with Its in. 



In a 3-year test with 25 varieties of cowpeas unknown, Brabham, Whippoor- 

 will. Iron, Clay, and Iron-Blackeye, and in a similar experiment conducted for 

 6 years Clay, Unknown, New Era, Whippoorwill, Iron, and Groit led in average 

 yield of seed in the order given. In 1917-18 Clay, Unknown, and Iron stood 

 first in forage production, the average yield being 2,573, 2,366, and 2,147 lbs. per 

 acre, respectively. 



In 1916 Meyer T. S. No. 228, the leading variety in a test with soy beans, 

 yielded 3,080 lbs., and in 1918 a single variety designated Biloxi yielded 3,980 lbs. 

 of cured forage per acre. Four varieties of Canada field peas planted with oats 

 on January 11 were injured by a low temperature of 15° F. in February, which 

 reduced the yields. The highest yield of forage, 900 lbs. per acre, was secured
