Wheat alternated wtth bare fallow in comparison with wheat alternated with 

 corn resulted in estimated average profits per acre of $6.89 with wheat and 

 corn and $2.37 with wheat and fallow for a 7-year period at the Judith Basin 

 substation. At the Huntley substation the average profits per acre over a 

 4-year period were estimated to be $9.05 for wheat and corn and $3.70 for 

 wheat and fallow. 



Field peas sown in drill rows 8 in. apart and in 24-in. rows, using 3 bu. of 

 seed per acre, have given average yields of 44 and 42 bu. per acre, respectively, 

 for the past 5 years. Plantings In 24-in. rows, using 1.5 bu. of seed, yielded 



35.6 bu. per acre, while 36-in. rows have averaged from 30.3 to 36 bu. per acre. 

 [Field crops work in Tennessee] (Tennessee Sta. Rpt. 1914, VP- 269-211, 



277-279). — Reviewing the progress of work With field crops for 1914, brief 

 notes are presented on cultural tests with red clover, alfalfa, cowpeas, wheat, 

 and corn ; on field tests with Sudan grass, honey sorghum, cotton, winter 

 beardless barley, sweet clover, and smooth-headed millet ; and on the value of 

 the subsoil plow for Tennessee conditions. 



Progress report. Substation No. 5, Temple, Tex., 1910-1914, D. T. Kil- 

 LOUGH (Texas sta. Bui. 215 (1917), pp. 3-28, figs. 8).— This bulletin reports re- 

 sults of testing, improvement, and production studies with cotton, cowpeas, soy 

 beans, Sudan grass, corn, and the grain and forage sorghums, together with 

 rotation experiments and field tests comparing different methods of soil prepara- 

 tion. Attempts to establish satisfactory fruit, truck, and garden crops on the 

 substation are briefly noted. 



Data on rainfall from 1889 to 1914, inclusive, are presented, the annual pre- 

 cipitation varying from 20.45 to 59.28 in. with an average annual rainfall of 



35.07 in. The summer months of 1912, 1913, and 1914 were especially dry, al- 

 though the total annual precipitations amounted to 29.41, 43.65, and 46.74 in., 

 respectively. Weather conditions were deemed more satisfactory for cotton 

 than for corn. 



Rotation tests with cotton resulted in yields amounting to 849.87 lbs. of seed 

 cotton per acre for cotton grown in rotation and 522.9 lbs. for cotton following 

 cotton. Similar tests with corn resulted in yields of 25.6 bu. per acre for corn 

 grown in rotation and 17 bu. for corn following corn. Observations on the 

 root rot disease, Ozonvum omnworum, of cotton in 1914 revealed the fact that 

 a loss of 59 per cent was sustained from this disease by cotton grown on land 

 continuously cropped to cotton, whereas in a 4-year rotation a loss of only 0.6 

 per cent occurred. 



Leading cotton varieties in tests conducted during 1912-1914, inclusive, in- 

 cluded Union Big Boll, Lone Star, and Mortgage Lifter, with average yields of 

 lint cotton of 339.82, 339.39, and 317.34 lbs. per acre, respectively. 



Variety tests with cowpeas for seed for the period of 1912-1914, inclusive, 

 resulted in average yields ranging from 50.23 lbs. per acre for Peerless to 404.25 

 lbs. for New Era. Cowpea variety tests for forage in 1912 resulted in yields 

 ranging from 966 lbs. of cured hay per acre for Peerless to 3,476 lbs. each for 

 Iron and Clay. 



Soy bean variety tests conducted from 1912-1914, inclusive, gave average 

 yields of seed ranging from 1 bu. per acre for Jet to 3.9 bu. for Meyer. 



Satisfactory yields of grain are said to have been obtained with the sor- 

 ghums, especially feterita which is deemed to have its greatest value as a 

 catch crop. Of the saccharin sorghums tested Sumac has given uniformly 

 better yields of forage and hay. Sorghums and cowpeas grown together for 

 hay in 1912 indicated that better results could be obtained by growing the 

 crops separately and mixing the hay when feeding. Sumac sorghum gave bet- 

 ter results than Amber for such mixtures, while there appeared to be no prefer-
