EXPERIMENT STATION RECORD. 



reports the results of experiments in pasturing and in growing a num- 

 ber of forage crops for pasture and soiling purposes. I >escriptive and 

 cultural notes are given for each crop. A two-year-old heifer, not giv- 

 ing milk and weighing about 800 lbs., was pastured on plats of rye and 

 sorghum to ascertain the amount of land required to sustain a cow 

 during summer. The results obtained are given in the following table: 



Length of time an acre of rye or sorghum furnished pasturage for ont cow. 



Among the forage crops tested sorghum, red and white Kafir corn, 

 Canada field peas, hairy vetch, burnet, Jerusalem corn, millo maize, 

 soja beans, and cowpeas are considered adapted to the climate and the 

 soil and of some value as forage. The yields and the food ingredients 

 per acre produced by some of these crops are given in tables. The 

 significance of the different food constituents is explained in a popular 

 way. 



On the change of the composition of green fodders at different 

 periods of vegetation, P. AzARTEVIOH (Zapi. Novo- Alexandria; Inst. 

 SelsJc. Khoz. i Lyesov., 10(1897), Xo. 2, pp. 19-24).— A small plat of ground 

 was sowed with Yicia narbonnensis; the development of the plants 

 proceeded normally. The Yicia was mowed at intervals of 2 weeks, 

 and the plants were dried and analyzed. The author concludes that 

 the content of the crude protein in Yicia continually decreases during 

 the period of vegetation. 



The amount of albuminoids gradually decreases with age, but in 

 comparison to the crude protein it increases. This is explained by the 

 transformation during growth of noualbuminous bodies into albumi- 

 nous, a transformation which is less pronounced in the case of Yicia 

 than in that of the Grainineai. 



Concerning the ash, no regularity was observed in the change of the 

 percentage content until flowering, after which period there was a con- 

 tinual decrease. 



The content of fat remained unchanged until flowering, after which 

 it gradually decreased. 



The amount of cellulose continually increased with the growth of 

 the plants. 



There was a continual though slight increase in the nitrogen-free 

 extract. 



The sum of the nitrogen-free extract plus the fat increases until 

 flowering, but decreases after flowering. This is in entire agreement 

 with the results of E. Wolf and Ritthausen, who experimented with 

 red clover and alfalfa. — P. fireman.
