FIELD OEOPS. 225 



The former loss was considered comparable with Peruvian cotton and valued 

 at i cts. more per pound than the saw-ginned sample. 



An excellent quality of broom corn from 24 to 30 in. in length was produced 

 in 90 days. The ratooning of broom corn proved a failure, as the yield was small 

 and the quality inferior, each, stalk having coarse central stems in the brush. 

 Fall planting of broom corn also proved undesirable, as the brush from this crop 

 likewise contained coarse stems, which the spring (April 4) planting did not. 

 It is suggested that broom corn may be planted between the rows of corn in 

 the .spring. 



Growing crops in western Nebraska, W. P. Snydek and W. W. Bukr 

 {Nebraska Sta. Bui. 135, pp. S-J/l, figs. 6). — This bulletin reports continuations 

 of trials, previously noted (E. S. B.., 24, p. 723), with winter wheat, spring 

 wheat, oats, barley, spring emmer, and corn, with regard to varieties, rate of 

 seeding, time of seeding, and effect of previous crop and tillage. Reports on 

 the production of sorghum, Kafir corn, milo maize, brome grass, and alfalfa 

 are also presented, with data as to rotations and tillage methods. 



It is noted as results of observations to date, that " summer tilled land has 

 jn-oduced on an average 10 bu. more than twice that produced on land not 

 summer tilled when sown to winter wheat. Turkey Red and Kharkov have 

 given the highest yields and for this locality we consider them practically the 

 same. Whenever there is a shortage of moisture thin seeding of winter wheat 

 on summer tilled land has given the best results. Seeding winter wheat by 

 September 15 except in dry years has given best average results in this lo- 

 cality. Early seeding of spring small grains has given the best average yields. 

 Spring grains have given a heavier yield on summer tilled land than on land 

 not summer tilled, but only in the case of barley has it been at all proiitable to 

 summer till for spring grains. 



" Seeding oats, barley and emmer nt 6 pk. per acre has given the best aver- 

 age results. In all spring small grains the earlier varieties have given the best 

 average results. Common 6-row barley has proven the best of all varieties so 

 far tested. Winter emmer has not proven hardy in this locality. Drilling 

 small grain has in practically all cases given an increased yield over broad- 

 casting. 



" Durum wheat and barley have produced more feed per acre than other 

 spring small gi-ains. Listing corn has proven much more profitable than surface 

 planting. Ordinary cane (sorghum) has proven the best annual forage crop. 

 Brome grass has not proven profitable either as a pasture grass or as a hay 

 crop. Alfalfa is the most valuable forage crop that can be grown in the valleys. 

 On the table-land it is of questionable value when sown broadcast, except 

 during years of abundant rainfall or when sown on -some place which receives 

 run-off water from adjacent land." 



Charts, diagrams, and tables give data on precipitation at North Platte, 

 Nebr., for the past 3S years, and on the rate of evaporation from a free water 

 surface for the months of April to September for 5 years, ranging from 40,191 

 to 49,702 in. 



[Field crops work at the Williston substation, 1910], E. G. Schollander 

 iXorth Dakota Sta., Rpt. Williston Snbsta., 1910, pp. 12-52. figs. 6).— Tabulated 

 data are given of variety tests v/ith wheat, oats, barley, flax, potatoes, and sugar 

 beets. Velvet Don, a durum wheat, produced the lowest yield of 3.7 bu. in 

 1910 as well as the highest yield of 36.8 bu. per acre in 1909. Oats yielded 

 from 3.6 bu. in 1910 with G. I. 492 to 104.1 bu. by the same variety in 1909. 

 Barley yielded from 1.2 bu. in 1910 with success to 57.8 bu. by Russian in 1909. 



Sowing wheat August 14 gave a higher yield than sowing August 27, Sep- 

 tember 11, or September 25.
