730 EXPERIMENT STATION RECORD. 



Bobs rust-proof wheat proved slightly earlier and less rust resistant than 

 Victoria, but yielded about 10 bu. per acre. 



From the Veliko-Polovetz Experiment Station of the Byelaya-Tserkov 

 Estates of Countess M. E. Branitski, I. Skrodski (Klioziaistvo, 1909, No. 12; 

 ahs. in Zhur. Opytn. Agron. (Riiss. Jour. Expt. Landw.), 11 (1910), No. 1, pp. 

 96, 97). — Clover was cultivated by Rafar's method, which aims to obtain clover 

 seed in the first year of growth. The sowing takes place early, in rows, 

 without a top-dressing. The yield was 9 poods per dessyatina (120.24 lbs. 

 per acre). 



Sugar beets planted in 13-iu. rows at distances of 4i, 6, and li in. yielded 

 1,454, 1,470, and 1,170 poods per dessyatina respectively. 



Fallow culture according to data of the Poltava Experiment Field, K. 

 Mankovski {SelsJc. Khoz. i Liesov., 1909, Aug.; abs. in Zhur. Opytn. Agron. 

 (Russ. Jour. Expt. Landw.), 11 {1910), No. 1, pp. 93-95). — The author believes 

 that the advantages of early fallow are unquestionable, but since farmers 

 frequently do not find time to plow until June a means was sought for dimin- 

 ishing the injurious influence of the late plowing of the fallow. Such a means 

 was found in the early surface cultivation of the fallow in the spring with a 

 Charles plow. Three such cultivations increased the rye yield 23 per cent and 

 the wheat yield 42 per cent. 



The grazing ranges of Arizona, J. J. Thobnber (Arizona Sta. Bui. 65, pp. 

 2^5-360, pis. 13, figs. 5). — The author devotes successive chapters to climatic 

 conditions ; forage plants of Arizona and their relation to rainfall ; protected 

 enclosures v. open ranges ; storm water embankments or dams ; cultural opera- 

 tions on the small range reserve; and the past, present, and future of grazing 

 ranges. 



He concludes that under present conditions where the chief forage plants 

 are winter and summer annuals, mesquite, and cacti, fencing ranges at the 

 lower altitudes is not warranted. The most economical plan for handling such 

 ranges is apparently moderate gi'azing, especially after the plants have begun 

 to dry up in the spring. The best forage returns are secured from salt- 

 bushes when they are kept moderately closely browsed without being eaten 

 to bare stumps or allowed to form brushy thickets. 



Seven embankments ranging from 270 to 594 ft. in length and from 12 to 

 24 in. in average height were built to test their practicability for range 

 reclamation purposes. Swales, old roads, and other favorable situations within 

 a small range enclosure were chosen for the purpose of confining the rainfall 

 of a more or less definite watershed on a limited area. The 7 embankments 

 benefited not more than 5.7 acres at a total cost of $115 for building. The 

 heavier growth made over the benefited areas by certain native plants " is 

 by no means commensurate with the cost of constructing the dams." 



Work already reported (E. S. R., 13, p. 731) is summarized, together with 

 cultural work with grama, blue stem, dropseed, triple-awned, porcupine or 

 needle, and miscellaneous grasses, Metcalf's bean, saltbushes and related 

 plants, annual forage plants, sorghum and allied species, and root planting 

 experiments with miscellaneous species. In the cultural work practically 

 all the grama grasses did well in the forage garden when flooded in addition 

 to the heavy rainfall but gradually died out with average summer rains and 

 little or no flooding from storm water. Silver top or feather blue stem yielded 

 about f of a ton to a ton of hay per acre with average rainfall and annual 

 flooding, and resisted prolonged drought remarkably well. The drop seed 

 grasses including sacaton started well on areas occasionally flooded with 

 storm water but died out completely before the rains of the following summer 

 begun. With flooding and heavy rainfall Texas millet, finger grass, shama
