 sugar beets by Briem and von Proskowetz, and the hybridization of the cereals

Campbell's soil culture manual, H. W. Campbell {Lincoln, Nebr., 1901, pp. 

 320, pi. 1, figs. 52). — This book, a farmers' guide adapted to semiarid regions, 

 describes the different implements used in dry farming, discusses the value 

 and methods of soil treatment to conserve soil moisture, and gives directions for 

 growing the ordinary farm crops under semiarid conditions without irrigation. 

 Special attention is given to corn, wheat, potatoes, sugar beets, alfalfa, and tree 

 culture. 



Proceeding's of the trans-Missouri dry farming congress {Proc. Trans- 

 Missoiiri Dry Fanuiiiy Cong.. lUOl. pp. 2-'f8). — A collection of the different papers 

 jiresented at this congress held at Denver, January 24-2G, 1907, together with 

 the discussions on different phases of farming in the semiarid regions without 

 irrigation. 



Report of work at McNeill branch, experiment station for 1906, E. B. 

 Ferris (Mississippi 8ta. Bui. 101, pp. 1-Ji ; 11-20, figs. 2). — General statements 

 with reference to the year's work at the station are given. As in previous years 

 fertilizer tests were made with a number of crops. 



In experiments with cotton, in which as a rule cotton-seed meal, acid phos- 

 phate, and kaiiiit were applied at the rate of 100 lbs. each per acre in different 

 combinations, the best yield, 1,060 lbs. of seed cotton per acre, was secured from 

 the use of acid phosphate and cotton-seed meal. In another test conducted to 

 determine whether the addition of kainit to cotton-seed meal and acid phos- 

 phate would increase the yield, the use of acid phosphate and cotton-seed meal 

 gave 1,540 lbs., while the application containing iTm) lbs. of kainit in addition 

 gave only 1,48.5 lbs. of seed cotton per acre. The effects of manure left by 

 cattle in the winter of 1902-3 was still quite perceptible this year. The yields 

 of different varieties of cotton compared ranged from 975 lbs. to 1,385 lbs. of 

 seed cotton per acre. The leading sorts and their yields were as follows : Cook 

 Improved 1,385 lbs., Culpepper 1,300 lbs.. Cleveland Big Boll 1.2(55 lbs., Hunni- 

 cutt Big Boll 1,260 lbs., Toole Improved 1,245 lbs., Rogers 1,220 lbs., and 

 Florodora 1,210 lbs. 



The average yields of corn per acre in the fertilizer tests ranged from 14.6 bu., 

 on the plat receiving no fertilizer, to 28.6 bu. on the plat receiving 100 lbs. 

 each of cotton-seed meal, acid phosphate, and kainit. The lowest yield on any 

 fertilized plat, 18.6 bu., was secured where 100 lbs. of kainit was applied alone. 

 The plat given 100 lbs. acid phosphate alone ranked second in yield with 28.3 

 bu. On parked land receiving 100 lbs. each of acid phosphate and cotton-seed 

 meal 36.5 bu. was secured, and only 33.3 bu. when in addition 100 lbs. of kainit 

 was given. The leading varieties of corn and their yields per acre were as 

 follows : Cocke Prolific 35.3 bu.. Eureka 35.1 bu., Mosby Prolific 32.8 bu., and 

 Early Breadfield 32 Iiu. 



Oats and vetch, sown in the proportion of 4 to 1 on land fertilized with a light 

 application of stable manure and 400 lbs. per acre of a mixture of equal parts of 

 acid phosphate and cotton-seed meal, were cut on April 30 and produced 6,090 

 lbs. of well cured hay per acre. The land then produced a crop of 30 bu. of 

 Mosby Prolific corn and a fair crop of cowpeas for turning under in the fall. 

 Brief cultural notes on different forage crops are given. 



The best average yield of plant cane, 39,050 lbs. per acre, was secured where 

 400 lbs. of cotton-seed meal and 200 lbs. of acid phosphate had been applied. The 

 check plat produced 31,245 lbs. In experiments with stubble cane a mixture
