1918] FIELD CROPS. 31 



In flax variety tests. Russian (N. Dak. No. 155) has given the highest 

 average yield for the period of 1912 to 1916, inclusive, 10.9 bu. per acre. 

 Primost (Minn. No. 25) and North Dakota Resistant No. 52 gave average yields 

 of 9.9 and 9.3 bu. per acre, respectively. Select Russian (N. Dak. No. 1215), 

 with a yield of 10.7 bu. for 1916 and an average yield of 12.3 bu. for 1914-1916, 

 inclusive, is regarded as about equal to Russian (N. Dak. No. 155). 



From corn variety tests reported for 1916 and for the period of 1913-1916, 

 inclusive, it is concluded that Northwestern Dent, Payne White Dent, and 

 Gehu Flint are best adapted to this region. Gehu Flint yielded 46.6 bu.. North- 

 western Dent 42.2 bu., and Payne White Dent 43.8 bu. per acre in 1916. 



Potato variety tests are reported for the period of 1914-1916, inclusive. The 

 highest average yield, 133.1 bu., was secured from Selection 4452, developed 

 from Professor Maerker and Silver Skin. Peerless was second, with a yield of 

 122.7 bu. per acre, and Olds Prolific and Burbank third and fouith, respec- 

 tively, with average yields of 112.8 and 111.6 bu. per acre. 



Tests with root crops in 1916 included half sugar stock beets. Golden Tankard 

 stock beets. Mammoth Long Red stock beets, and stock carrots, and resulted 

 in yields amounting to 29.76, 24.63, 23.75, and 10.45 tons per acre, respectively. 



[Field crops studies at] substation No. 1, Beeville, Texas, 1910-1914, E. E. 

 BiNFORD (Texas Sta. Bid. 2U (1911), pp. 3-19, 19, 20, 26, 21, fig. i).— Variety 

 and cultural tests with cotton, corn, oats for hay, legumes, grain sorghums, 

 Sudan grass, and miscellaneous forage crops conducted at the Beeville sub- 

 station from 1910-1914, inclusive, are reported. Climatological data for the 

 period are noted and briefly discussed. 



The highest average yield of .seed cotton per acre secured in variety tests 

 in 1912 and 1914 was 964.84 lbs. from Mebane, with King second with 951.1 

 lbs., Rowden, Crowder, and Lone Star, with average yields of 923.13, 921.29, 

 and 708.04 lbs. per acre, respectively, are also deemed well-suited to local 

 conditions. A comparison of frequent and infrequent cultivation of cotton 

 gave 2-year average yields of 684.4 and 681.7 lbs. of seed cotton per acre, re- 

 spectively. 



In corn variety tests, Thomas, with a yield of 25.44 bu., and Surcropper, 

 with 24.04 bu. per acre, gave the highest average yields for tests conducted in 

 1913 and 1914. Relative yields of corn from 120 different ears of the same 

 variety varied from 17.57 to 48.86 bu. per acre. The data reported show that 

 neither the weight nor the size of the ear are an indication of its yielding 

 power. 



Rate-of-seeding tests with corn were conducted during 1913, an extremely 

 dry season, and 1914. The seeding rates varied from 2.420 to 9,680 stalks per 

 acre. The highest yield in 1913 was secured from the thinnest seeding rate 

 and amounted to 10.9 bu. per acre. The 1914 results showed a gradual increase 

 in yield up to a seeding rate of 4,840 stalks per acre, when a yield of 37.08 bu. 

 was obtained, although the maximum yield, 39.92 bu., occurred with a seeding 

 rate of 7,260 stalks per acre. Tests were conducted in 1913 and 1914 with corn 

 planted (1) in rows 3 ft. apart with the stalks 3 ft. apart In the row, (2) in 

 rows 6 ft. apart with the stalks 18 in. apart in the row, and (3) in 8-ft. rows 

 in pairs 9 ft. apart with the stalks 18 in. apart in the row. Each plat was left 

 with 4,840 stalks. The average yields for the different planting methods 

 amounted to 23.4, 21.87, and 20.64 bu. per acre, respectively. The results are 

 held to indicate that the distribution of the corn stalks on the land is rela- 

 tively unimportant, although the wider planting distances facilitated clean 

 cultivation. These experiments are to be continued.
