beets. The percentage of dry matter was highest in the fidd beets and lowest 

 in the turnips. On October 13 the yields of dry matter per hectare were 8.58, 

 7.60, and 8.24 tons, and on Nuvember 10, 7.93, 8.28, and 8.18 tons for the turnips, 

 swedes, and field beets, respectively. During the period of maximum growth, or 

 from the middle of August to the middle of September, the crops produced over 

 a ton of dry matter per hectare per week. Immediately after this period the pro- 

 duction of dry matter fell to 0.5 ton, and a little later to 0.3 ton per hectare per 

 week, while after October 13 no further production of dry matter was per- 

 ceptible. Analyses of the forage made at various intervals from August 4 to 

 October 13 indicated that the more rapid formation of dry matter took place in 

 the first half of September, while the greater percentage of water was found 

 prior to September 1. 



The results of planting these root crops at different distances were in favor 

 of planting in rows 60 cm. apart with the plants 25 cm. apart in the row, or 

 1,500 sq. cm. (132 sq. in.) of space per plant. These results were influenced to a 

 certain extent by a poorer stand on the closer planted plats. 



In a variety test Ostersundom turnip outyielded Bortfeld and Yellow Tankard, 

 and Red Eickendorf field beets produced a higher yield than Barres Halflong. 

 Sati.sfactory yields of a variety of swedes and of sugar beets are reported. 



[Field crops], B. C. Bukt {Rpt. Cawnpore [India] Agr. Sta., 1916, pp. 2-iO). — 

 This reports work at the Cawnpore experiment station (E. S. R., 31, p. 732) 

 for the year ended Juno 30, 1916. 



Notes are given on fertilizer experiments with wheat, and green manure tests 

 and cultural experiments with wheat, cotton, gram, sugar cane, millet, pigeon 

 peas, tobacco, barley, flax, and peanuts. Other experiments reported included 

 deep V. shallow sowing for maize, maize and peanuts as a mixed crop, tests of 

 different spacings with American cotton, rotation tests, and fodder crop ex- 

 periments. 



[Field crops], A. C. MacDonald {Dept. Agr. Brit. East Africa Ann. Rpt. 

 191S-lIi, pp. 191, pi. J; 191^15, pp. IJtS). — These reports continue work pre- 

 viously noted (E. S. R., 20, p. 793). Brief notes are given on the production of 

 sisal, cotton, flax, corn, wheat, tobacco, and certain tropical plants in British 

 East Africa, with supplementarj- reports from the government experimental 

 farms at Klbos, Nairobi, and Kabete. 



The advancement of the agricultural industries and of stock breeding in the 

 Protectorate is summarized for the past seven years. 



Cultural experiments conducted in Denmark with different mixtures of 

 the seeds of forage plants. E. Liniihard (Tidsskr. Plnntcavl, 22 (1915), No. 4- 

 pp. 558-118, figs. 2; abs. in Internet. Inst. Agr. [Rome], Internat. Rev. Set. oti// 

 Pract. Agr., 7 {1916), No. 2. pp. 22^. SS5). —Tho author di.^^cusses the results 

 obtained in a series of experiments with mixtures of seed of forage plants cover- 

 ing a period of twelve years, 10(K) to 1912. The data are presented in tabular 

 form. A mixture recommended by Nielsen and composed of the following in- 

 gredients per acre was used as a ba.sis for comparison : Early red clover 6.4 lbs., 

 Trifoliutn hylridum 1.8 lbs., T. rcpcns 0.3 lb., Agropyron repcns 3.2 lbs.. Arena 

 fatua 3.2 lbs., PMeum pratense 1.8 lbs., Festuca pratensis 1.1 lbs.. Lolium 

 perenne 1.8 lbs., and L. italicum 1.6 lbs. 



A summary is given of the results obtained with ten other Graminese-Legutoi- 

 nosae combinations. These together corresponded to the most varied cultural 

 conditions, and, when used according to their individual adaptations, gave much 

 better results than the Nielsen mixture.
