highest in tlae test and ranged abont 5 per cent higher than that of_ either 

 Dwarf milo or feterita. Tlie yields of seven valuable varieties for the 6-year 

 period ending with 191S showed that Dwarf hegari, together with other leading 

 sorts, gave much better yields on medium heavy soil than on light soil. Some 

 of the best yields from April and May plantings represented two grain crops 

 harvested from the same plats in one season. As the early crop is frequently 

 largely lost through bird injury, a single crop planted either late in June or 

 early in July is regarded as generally most profitable. Results of spacing tests 

 in 1918 with Dwarf hegari grown in rows 42 in. apart were in favor of 6 to 8 

 in. between plants in the row. The best yields of a very good strain of Dwarf 

 milo secured by 28 farmers in 1918 were reported from rows about 3 ft. apart 

 with plants 14 to 24 in. apart in the row. The average planting date of fields 

 producing good yields was from June 20 to July 15. 



The average seed yields of different strains of flax for 1917 and 1918 ranged 

 from 8.3 to 19.8 bu. per acre. Plantings made from December 15 to January 15 

 gave the best yields. The data in a rate of seeding test indicated that when 

 flax is broadcasted for seed production from 30 to 40 lbs. of seed per acre is 

 most desirable. 



The Tangier pea, introduced from Turkestan, compared with other varieties 

 produced at the rate of 4.44 tons of green material and 1.13 bu. of seed per 

 acre. Osceola and Georgia velvet bean varieties yielded 193 lbs. and 266 lbs. 

 of seed per acre, but did not prove to be satisfactory in forage production. 

 Horse beans planted in November and harvested in May produced 2.49 tons of 

 green material per acre, but the seed production was not sufficient to compare 

 favorably with field peas as a soiling or pasturing crop. Of several varieties 

 of forage sorghums Dwarf Java produced 16.6 tons of green forage per acre, 

 and when left to mature seed gave a yield of 57.2 bu. per acre. Giant Bermuda 

 grass (Cijnodon dactylon maritimus) became well established and made a very 

 good growth during a part of the year, but it did not prove more vigorous or 

 productive than common BeiTuuda grass (C. dactylon). 



Variety tests with potatoes at the farm have indicated that Irish Cobbler, 

 White Rose, Red Triumph, and Early Ohio, in the order named, are the most 

 suitable for the region. The 5-year average production of marketable potatoes 

 for Irish Cobbler was 86.5 bu. per acre, but in 1918 White Rose ranked first 

 with a yield of 168 bu. per acre. Irish Cobbler was found to be the best 

 summer keeper of the varieties grown. White Vineless sweet potatoes, one of 

 the most dependable varieties under the conditions of the farm, showed a 4-year 

 average yield at the rate of 9.53 tons per acre. 



[Field crops work at the Indiana Station] {Indiana Sta. Rpt. 1919, pp. 

 61-64) ■ — ^The work with field crops during the year ended June 30, 1919, is 

 briefly described. 



The variety tests noted have been reported upon largely in an earlier publi- 

 cation (E. S. R., 40, p. 735). The results of studies in crop cultural methods 

 were in favor of drilling soy beans solid at the rate of about 1 bu. per acre on 

 relatively clean and mellow ground, and of planting A bu. per acre in rows for 

 cultivation on ground that is weedy or tends to crust and bake. The best 

 yields of buckwheat were secured from seedings made late in July or early in 

 August. Seeding at the rate of 7 pk. per acre proved preferable for Michigan 

 Amber wheat. This variety outyielded the Marvelous or Stoner at all rates 

 of seeding. ^ 



Sudan grass gave the best yields when seeded early in June and drilled solidj 

 at the rate of 32 lbs. per acre. Analyses of the cured hay showed 10.3 per cent 

 of protein as against 5.4 per cent in sorghum hay and 8.2 per cent in Golden
