754 EXPERIMENT STATION RECORD. j 



folk rotations represent extreme methods of extensive and intensive farming, reepec- 

 tivel V. The results indicate that by improved methods of cultivation the yields in the 

 3-course system may be increased 3 or even 4 fold. — p. fireman. 



Range improvement, J. J. Thornber {Arizona Sta. Ept. 1902, jjp. 261, 262).— 

 A brief outline is given of the work in range improvement as carried on by the 



station. 



Hanna barley, A. Cserhati (Ztschr. Landw. Versiichsir. Oesterr., 5 {1902), No. 

 10, PI I. 1141-1207).— Resnlts of a series of cooperative variety and fertilizer experi- 

 ments with Ilanna barley in Hungary are given. It is concluded that this variety 

 is the best for brewing purposes, and its wide and rapid distribution is regarded as 

 bearing out this conclusion. The advantages of the variety consist in its early 

 maturity and its greater productiveness and weight. 



Experiments with cotton in 1902, G. P. Foaden {Jour. Khediv. Agr. Soc. and 

 School Ayr., 4 {1902), No. 6, pp. 216-229) . — A report on fertilizer and rotation 

 experiments with cotton, carried on at the experimental farms of the Khedivial 

 Agricultural Society at Ghizeh and Mit-el-Diba in cooperation with many private 

 farmers, is given, together with general directions for the culture of the crop. A 

 comparison of commercial fertilizers with barnyard manure resulted in a marked 

 financial benefit in favor of the barnyard manure. The use of superphosphate was 

 found valuable, and the results of experiments favored the method of applying part 

 of the total (juantity before and the remainder after planting. Potash gave practi- 

 cally no increase in yield. An application api)roximating 400 lbs. of superphosphate 

 and 100 1V)S. each of nitrate of soda and sulphate of ammonia per acre gave the high- 

 est yield of cotton. In a rotation test cotton gave better results when grown after 

 berseem than when following wheat. 



Egyptian cotton, A. J. McClatchie {Arizona Sta. Rpt. 1902, pp. 251,252).— 

 Ill 1901 several varieties of Egyptian cotton were grown under irrigation. The yields 

 per acre for the different varieties were as follows: Abbasi, seed cotton 1,580 lbs., 

 lint 460 lbs. ; Mitafifi, seed cotton 1,150 lbs., lint 275 lbs. ; and Jannovich, seed cotton 

 500 lbs. The results thus far obtained indicate that Abbasi is the most profitable 

 variety for the region and that it should be planted about the middle of March and 

 given a moderate quantity of water with good cultivation. 



Rotation and inoculation of leguminous crops, C. Fruwirth {Zti^chr. Landv!. 

 Verf<neh.^ir. Ck'Mcrr., 5 {1902), No. 4, pj>. 666-fl74)- — The results of rotation experi- 

 ments with leguminous crops are reported. Clover and lupines gave better yields 

 when grown after some other leguminous crop than when grown on soil which had 

 not produced a crop of that class for a series of years. The results with vetch in this 

 respect were not so marked. On soil which had produced a leguminous crop the year 

 before, lupines gave the highest yield as compared with clover and vetch. Similar 

 returns were obtained from a soil "which had produced a leguminous crop for 2 suc- 

 cessive years prior to these tests. Lui)ines gave the highest yield of seed after clover 

 and the smallest yield, with the highest yield of straw, after vetch. The best yields 

 of green fodder from vetch were obtained when this crop was grown after clover, 

 while clover itself was most productive after lupines. Small yields were olitained 

 where luj^ines, vetch, and clover were grown after beans. 



It was fomid that growing lupines, flat peas, and garden beans for 2 years in suc- 

 cession on the same soil was advantageous to the second crop. Vetch after vetch and 

 clover after clover was not beneficial, but this is not believed to be entirely due to 

 the rotation. 



Inoculating soil with the special bacterium for each of the leguminous crops grown 

 gave increased yields. 



Studies on the potato, E. Breal {Am). Agron., Q8 {1902), No. 11, pp. 545-576, 

 Jig. 1). — This article reviews important work on the potato by different investigators 

 and presents the results of the experiments conducted by the author.
