32 EXPEEIMENT STATION RECORD. [Vol.35 



Rahar (Cajanvs indicus) sown in June produced heavier yields than sowings 

 made in July. 



[Field experiments at Dumraon Experiment Station, 1914—15], G. Sher- 

 RARD (Rpt. Dcpt. Ayr. Bihar and Orissa, 1914-15, pp. 38-4^^).— The different 

 lines of work pursued during the year are briefly described. The results of 

 manurial tests with rice showed that an annual application of about 400 lbs. 

 of cow manure per acre for 4 years was distinctly profitable as compared with 

 other treatments, and gave better returns even than the use of double the 

 quantity. 



[Experiment station work in New South Wales, 1914^15] (Rpt. Dept. Agr. 

 N. 8. Wales, 1915, pp. 132, pis. 12). — Brief general reports are presented on the 

 experimental work and other activities of the Bathurst, Berry, Coonamble, 

 Cowra, Glen Innes, Grafton, Trangie, Wagga, Wollongbar, and Yanco experi- 

 ment farms, and a number of demonstration farms. Experiments conducted 

 at Hawkesbury Agricultural College, Lambrigg, and Howlong are also briefly 

 noted. 



In a test of 13 varieties of oats at Cowi*a, a cross between White Ligowo and 

 Algerian ranked first in yield with about 36 bu. per acre, followed by Sun- 

 rise producing only a few pounds less. Bathurst No. 4 and Ruakura Rust 

 Resistant also gave promising yields. At the Hawkesbury Agricultural Col- 

 lege Cleveland and Warren wheats succeeded best and Ruakura oats was the 

 most rust-resistant and gave the highest yield. 



The outstanding feature of the ear-to-row tests in corn-breeding work at 

 the various farms was the variation in yield between the different rows. In 

 every test the highest yielding row produced more than twice as much as the 

 lowest yielding row. It was also found that some of the best yielding rows 

 were almost uniform throughout in type. A cross between Hickory King and 

 Boone County White corn is described as having the small cob and hard, 

 medium-large grain of Hickoi-y King but the deep, wedge-shaped kernels of 

 Boone County White. 



In selection experiments at Grafton with Learning corn the highest yielding 

 row gave 70.2 bu. per acre and the lowest 26.7. The average of 20 ears 

 selected from the crib w'as 45.5 bu., and the average of 16 field-selected ears 

 52.1 bu. per acre. No advantage was derived from selecting for two ears per 

 stalk, and ears selected from stalks thick at the base yielded better on an 

 average than those from thin stalks. Ears selected from plants with suckers, 

 especially if these also bore small ears, yielded higher in neai-ly every case 

 than ears from suckerless stalks. Ears drooping at maturity generally out- 

 yielded those erect at maturity. A correlation appeared to exist between 

 medium red color of the kernels and good type of ear. 



Results in experiments with Improved Yellow Dent showed that the highest 

 yields were obtained from ears selected from short or medium tall stalks. 

 Ears selected from very tall stalks gave low yields in almost every case, and 

 ears placed low on the stalk gave distinctly higher yields than ears high on 

 the stalk. Ears drooping at maturity yielded 9 per cent higher than erect ears. 



Results secured in breeding work with sorghum indicated a correlation of 

 earliness and dwarf stature with grain production, and lateness and tall fodder 

 growth with low seed production. The yield of individual rows ranged from 

 2| to 9^ tons of fodder per acre, and from 1.25 to 20.6 bu. of seed per acre. 

 The best row of a dual purpose strain yielded at the rate of 5.3 tons of fodder 

 and 24.6 bu. of seed per acre. 



[Effect of inoculation material on the development of wheat, rye, oats, and 

 barleyl {North Dakota Sla. Rpt. 1915, pt. 1, pp. 15, 16). — Seed of wheat, oats, 

 rye, and barley was treated with an inoculation material for which it was
