FIELD CROPS. 



[Experiments witli field crops], A. M. McOmie {Arizona Sta. Rpt. 1915, pp. 

 518-528, figs. 4). — Of 13 varieties planted as spring wheat, California Club pro- 

 duced the largest yield, 38 bu., and Turkey Red the lowest, 14.5 bu. per acre. 

 Chul and Early Baart yielded each 36 bu. per acre and Blue Stem 35.3 bu. 

 lied Chaff ranlced first with 55 bu. per acre among 15 varieties sown the latter 

 part of October, being followed by Blue Stem with 53.9, Turkey Red with 51. 

 and Kofoid with 50 bu. per acre. In this list of varieties, Marquis produced 

 47.8, Early Baart 47.8, Red Fife 47.5, and Red Russian 47.3 bu. In every case 

 fall-sown wheat outyielded the spring-sown and was also less subject to rust. 



Sixty-day and Texas Red oats also gave better yields from fall than from 

 spring planting. Black Eagar is described as a variety with black, oval, large, 

 and heavy seed, an exceptionally long panicle, wide coarse leaves, and heavy, 

 canelike stems, and as maturing readily at an elevation of 7,000 ft., where 

 the growing season is very short. 



Utah Winter, C. I. No. 592, produced the heaviest yield of 10 varieties of 

 spring-sown barley, being followed by Mariout and Blue Ilnll-less. Black Winter 

 emmer and spelt, both fall sown, yielded 3,630 and 2,970 lbs. per acre, 

 respectively. 



Of 25 varieties of corn under test, Sacaton Mexican June led in yield with 

 99 bu. per acre. Mexican White Flint and White Dent each yielded 85 bu., 

 while some of the varieties fell as low as 10 bu. 



The results of tests with Sudan grass showed that this crop is capable of 

 maintaining 20 sheep per acre continuously for 100 days. In a comparison 

 with Club Top, Sumac, and Amber cane for forage. Sudan grass gave a yield 

 of 16,920 lbs. of dry hay and Club Top, the best of the other three varieties, 

 14,000 lbs. per acre. The leading grain-producing sorghums for the year were 

 Shallu, Dwarf Black Hulled White Kafir corn, Yellow milo maize, and White 

 milo maize. 



Winter vetch gave a dry product of 13,400 lbs. and spring vetch of 16,750 

 lbs. pel- acre. A yield of 24 tons of sugar beets per acre is recorded for a 

 planting made November 14, as compared with nearly 8 tons for a planting 

 made February 9. The November plantings consistently exceeded the Feb- 

 ruary plantings for the last four years. A yield of a little over 2,000 lbs. of 

 sugar-beet seed is reported. Twelve varieties of flax ranged in yield from 

 83.5 to 36.5 bu. per acre. The leading variety of millet was Kursk. 



The best success with winter grains of any so far experienced at the Snow- 

 flake dry farm was obtained the past year, the yields ranging from 12 to 32 

 bu. per acre, with Turkey Red and Marquis leading in production. A yield of 

 about 1.100 lbs. of seed per acre was secured from the Tepary bean, while 

 Pink and Boetcher also gave good yields. 



At the Sulphur Spring Valley dry farm October seeding of small grains gave 

 better yields than later seeding. Marquis wheat produced the largest yield, 

 19.8 bu. per acre, while Turkey Red, Red Chaff, Early Baart, and California 

 Club also proved satisfactory. Barley and rye were found valuable as winter 

 pasture crops, and both produced grains after being pastured. Spring varieties 

 of grain seeded March 15 practically failed. Notes are given on the production 

 of crops on shallow soil underlaid with caliche and on deep soils with clay 

 and a porous or soft caliche subsoil. 



The crops succeeding best at this farm during the past two years were Kafir 

 corn, Shallu, Club Top, and other saccharin sorghums ; Whippoorwill cowpeas ; 

 Sudan grass; and Mexican June, White Wonder, Sherrod, Freid, White Flint,
