138 EXPERIMENT STATION RECORD. 



Weekly determinations of the elevation of the water table showed an average 

 depth to ground water of 4.43 ft. on April 1, 3.79 ft. on June 3, and 4.86 ft. on 

 December 27. 



Duty of water, G. H. True (Nevada 8ta. Rpt. 1911, pp. 27-30). — The irri- 

 gating of White Australian wheat 3 times before heading and twice after head- 

 ing with an application of 1.41 ft. of water was followed by larger yields than 

 any other method, viz, 45.6 bu. per acre. With 2 applications before heading 

 and one afterward of 1.033 ft. of water there was produced 42.5 bu. per acre. 

 Siberian oats gave the best yield, 60.8 bu. per acre, when treated with an appli- 

 cation of 1.107 ft. of water once before heading and twice after. With alfalfa 

 the heaviest yield of hay, 7.52 tons per acre, was produced by flooding to a 

 depth of 5.077 ft., but with flooding to a depth of 3.051 ft. per acre there was 

 produced 6.61 tons. Of 6 varieties of potatoes Blue Victor gave the best yield, 

 156.8 bu. per acre, with an application of water 4.433 ft. in depth. In a variety 

 test of sugar beets 23.13 tons were produced per acre by No. 21857, which con- 

 tained 19.8 per cent sugar in the juice and was of 87.6 per cent purity. Yields 

 with winter wheat, barley, rye, and oats are also noted. 



[Irrig-ation experiments and sugar beet investigations], G. H. Tkue et al., 

 C. S. Knight and F. L. Peterson (Nevada Sta. Rpt. 1912. pp. lS-22) .—This 

 paper reports further observations (see above) on the irrigation experiments 

 with White Australian wheat, Siberian oats, and alfalfa, variety tests with 

 spring and winter cereals, potatoes, and corn for silage. 



The results of sugar beet experiments show that continued cultivation 

 throughout the season produced better yields than other methods tried, that 

 the rate of seeding of 25 lbs. per acre gave larger yields than 15, 20, or 30 lbs., 

 and that i^ws 16 in. wide as against 18, 20, and 24 in. produced better yields 

 with plants 6 or 8 in. apart, and the 20-in. width better with plants 12 in. apart. 

 The 8-in. spacing in a row produced the highest yield of all, viz, 10.92 tons per 

 acre, with rows 16 in. wide. 



Report of the substation of the Swedish Seed Association at Lulea, 1911, 

 A. Ulander (Sveriges Utsadesfor. Tidskr., 22 (1912), No. 6, pp. 3J,3-351).~ 

 This report presents brief accounts of variety tests and breeding experiments 

 with grasses, barley, oats, and legumes for the year at this station, located in 

 extreme northern Sweden. 



Eield crop trials in Tromsoe County, B. R. Larsen (Tidsskr. Noiske 

 Landljr., 19 (1912), No. 5, pp. 193-205).— A report on trials with barley, hay 

 crops, turnips, and potatoes conducted during the last decade, and especially 

 since 1906, in the northernmost county of Norway (largely within the Arctic 

 circle). 



Cooperative experiments, E. Clifton (Netv Zeal. Dept. Agr. Ann. Rpt., 20 

 (1912), pp. 81-90). — Some of the results of the 400 cooperative experiments, in- 

 volving 5.205 plats, are here reported with rape, kale, marrow cabbage. Silver 

 beet, and wheat. 



Essex Dwarf rape yielded 29.55 tons and Giant Essex Broadleaf 38.54 tons of 

 leaves per acre, and the pasture capacity with sheep for the 2 varieties was 

 at the rate of 223 per acre for 14 days. Thousand-headed kale yielded 23.24 

 tons and Green Buda kale 26.96 tons of leaves per acre, and an acre of the 2 

 varieties was capable of pasturing 217 sheep for 14 days. Buda kale grew again 

 very rapidly after pasturing. Marrow cabbage yielded 30.14 tons leaves per 

 acre, and Silver beet yielded 51.72 tons leaves per acre. These 2 latter crops 

 have not yet been pastured.
