la tests with fall-sown cereals on the Prescott dry farm, early planting of 

 wheat and rye proved to be quite satisfactory, while later plantings were less 

 so. Barley winterkilled completely, and emmer yields were small. Rye seeded 

 early in rows 7 in. apart produced 3,200 lbs. of hay per acres and in 21-in. rows 

 slightly less than 2,000 lbs. Similar plats allowed to mature grain yielded 

 from 9 to 14 bu. per acre, while later plantings produced as low as 5.5 bus per 

 acre. The wheat yields amounted to about 2 bu. per acre more than the rye, 

 but in no case was the grain of the best quality. 



Sudan grass seeded in ]\Iay produced approximately 2 tons of hay per acre in 

 addition to a slight amount of pasturage. A portion harvested for seed yielded 

 about 550 lbs. of recleaned seed per acre. 



Plantings of different varieties of corn grown for forage produced from 

 2,960 lbs. of green fodder per acre for Reid Yellow Dent to 49,783 lbs. for 

 Papa go Sweet. 



Field peas and beans were considerably damaged by rabbits and prairie 

 dogs, and later by a bacterial blight said to be due to Pscudomonas phaseoli, 

 which entirely destroyed the peas and greatly reduced the yield of the beans. 

 It is deemed probable that the disease is identical with a similar infection 

 appearing on the same field about three seasons before. The maximum yield 

 of beans, 539 lbs. per acre, was secured from a planting of tepary. White 

 sweet clover produced a fair stand but made meager growth the fist season. 



Variety tests with sorghums resulted in yields of green forage ranging from 

 1,259 lbs. per acre for feterita to 11,001 lbs. for Amber and 11,159 lbs. for Club- 

 Top. Darso, a drought-resistant strain, developed by the Oklahoma Experi- 

 ment Station, is said to have given encouraging results at Prescott. 



Potato yields ranged from 920 lbs. per acre for a planting of Rural New 

 Yorker to 4,011 and 4,122 lbs. for White Rose and Early Rose, respectively. 



Seasonal conditions on the Sulphur Springs Valley dry farm are said to have 

 been so unfavorable as to render the results of little value. Mexican June 

 corn produced on the average 2,100 lbs. of green forage per acre ; tepary beans 

 sown as a catch crop after Sudan grass which had failed, 133 lbs. of seed, and 

 after an indifferent wheat crop, 121 lbs. ; and Dwarf Kafir and Club-Top 

 sorghum 7,350 and 2,G00 lbs. of green forage per acre, respectively. 



Average crop yields on the university farm amounted to 4 tons per acre for 

 alfalfa, 1 ton of hay per acre for barley, 5] tons of green forage for corn, 70 

 bu. of mature corn, 6 tons of green fodder for feterita, and 5 tons for milo 

 maize. Peanuts are thought to be well adapted to the soil and climatic con- 

 ditions of the region. 



[Report of plant breeding work in Arizona], G. F. Feeeman and W. E. 

 Bryan (Arizona Eta. Rpt. 1917, pp. ^5^-454, 456-461, fi<js. 3). — Observations on 

 selections of pedigree strains of alfalfa and hybridization and selection studies 

 with tepary beans and wheat are briefly reviewed in continuation of similar 

 work previously noted (E. S. R., 39, p. 736). 



Individual selections from a strain of alfalfa originating from a single plant 

 selection made in 1909 showed variations in the average yield per plant for three 

 cuttings ranging from 0.3 to 0.53 lb. Different varieties of alfalfa seeded on 

 i-aere plats in 1916 produced at the rate of from 7,723 lbs. per acre for Turkestan 

 to 16,223 lbs. for European. Due to its productivity and hardiness, hairy-leaved 

 Peruvian is said to be growing in popularity in the Southwest. 



Results secured during the past three years in a comparative study of Arizona 

 wheats are held to indicate that grain of excellent milling and baking quality 

 can be produced on irrigated land in tlie State, and that there are market! differ- 

 ences in the bread-making qualities of different varieties grown under identical
