The influence of external conditions on henip and hemp flber, J. Beiirens 

 ilirr. Liiiulir. ]'ers. Aiixl. A iif/iislciih.. IHii.'), pit. .'il-'/.i). — Th(> results of the ex- 

 pci-jnients here descrii)ed indicate that the free .access of li^'ht fails to influence 

 the (leveloi)inent of fiber in the hemp ])lant. 



A comparison of Iniproved Ligowo and Provence Gray oats, F. Riciiter 

 (/'rn(/. Af/r. el \ il. HJd. TA'.s-O, 27 {lf)06). No. J,r>, pp. .567-570).— In culture tests 

 of these vai'ieties tiie Provence (Jray yielded 2.4r)0 kff. per hectare and the 

 Lisowo 8.270 kg- The hectoliter weif^ht of the Liffowo was 4.3.5 k>;. and that 

 of the Trovence (iray 43 kg. 



It is conchided from the results secnred that Ligowo Improved might he 

 reconnnended for general culture either as a winter oats in southern localities 

 or as a sjiring variety in the more northern regions. 



Orchard grass. It. A. Oakley (C »S'. Dept. Apr.. I'lir. I'ldut In(lu,<i. liul. 100, 

 pt. ('). pp. ]<>. 1)1. 1). — This hulletin descrilx^s the methods followed in growing 

 orchard grass for h;iy, jKisture. and seed in different sections of the country. 



It is stated that orchard gr.ass yields on an average from 10 to 12 bu. of seed 

 per acre, which sells for ^].'2~) a husliel. When sown for seed it is advised to 

 sow 1 bn. of seed pen" acre, and when grown for hay or pasture to use more 

 than this (jnantity. Red clover sown with orchard grass at the rate of 1 bu. to 

 ." or 7 acres is considered a profitable mixture. Orchard grass sown together 

 with tall meadow oat grass and meadow fescue for hay and ])asture also gives 

 good results. The seed is harvested about June 15 to .Tune 25. The average 

 life of an orchard grass meadow is given as from 5 to 7 years. 



Potato cultui'e experiments, J. Behrens (Bcr. Ldiidir. \'er,^. Anst. Au- 

 <iHxt<uh.. ]!)0-'i, lip. .',7-(io). — The results secured showed that there existed no 

 definite relation between the weight of the seed tubers and the yield. The seed 

 tubers weighing 100 gm. each gave a higher average yield than those weighing 

 less, but the exceptions were very numerous. The starch content of the seed 

 tubers and that of the ])roduct secnred se(>med to bear no relation to each other. 

 The starcli jii-oduction of individual plants was also api)arently independent of 

 the starch content of the seed tnbiTs. 



Sugar beets in Kansas (Qiitirl. h'pt. Kaiis. lUL Aijr.. 2'> (1906), Xo. 09, 

 pp. 3,2. fifps. ()). — A series of articles giving the history and the present status of 

 the beet-sngar industry in Kansas, with a record of its progress since the pas- 

 sage of the State bonnty law in 1001. (Jener.-il directions on the culture of the 

 sugar beet are included, and growing sugar beets in the Arkansas valley in 

 K;insas is described. 



Report on fertilizer tests with sugar cane, C. Lemarie (Bill, fjeon. Indo- 

 Cliiiie. II. scr., 9 (1906), No. 53. pp. 629-635). — Fertilizer experinrents were con- 

 ducted on naturally poor soils, especially deficient in lunnus. 



The results showed that miner;ils .alone wer(> inelfectiv<> and that where 

 insufficient (inantities of barnyard manure were used the returns were also 

 unprofitable. A heavy dressing of barnyard manure gave a somewhat smaller 

 yield, but was nevertheless more profit:il)le than an ai)plication of barnyard 

 manure together with connnercial fertilizer. The author concludes that the 

 first need of the soil is a suiijily of lunnus. 



Sunflower culture and its profits in Russia, V. Wai.ta (Fiihrnui't^ Lniidir. 

 Zhl.. 55 (1906). No. 20. pp. 701-70S. fip. /).— The history (»f sunfiower culture in 

 Russia is given, together with a description of the methods followed. The tpian-
