FIELD CROPS. 303 



The author states that "excess of iiitrogeu has not made tlic crop 

 ' run to leaves,' nor has deticiency of plant food strikingly affected the 

 relative proportion of ears and stalks/' 



During years the Urst and second plats (cow manure and liog 

 manure) have yielded on the average the same amount of water-free 

 crop, the third plat (chemical fertilizers) has yielded more than eight- 

 tenths as much, and the fourth plat (potash) between five and six 

 tenths as much as the first two. There was a general falling off" in the 

 yield of all the plats during 5 years. 



As to food ingredients, the crop both of kernels and stalks on the 

 first 2 plats has been practically identical as regards chemical com- 

 position. The kernels of the crop on the third plat contained some- 

 what less mineral matter and fat and about 0.5 per cent less protein 

 than the crops on the first 2, with correspondingly more nitrogen-free 

 extract. The kernels in the crop on the jilat not manured had 2.3 per 

 cent less proteids than the first 2 j)lats, somewhat less ash and fats, but 

 more fiber and nitrogen-free extract. 



Mixed forage crops, C. A. Goessmann [Massachusetts Hatch. 8ta. 

 Ept. IS'J-'j^ pp. :JS8-;293). — The following mixtures were grown on well- 

 manured land: Vetch and oats; vetch and barley; oats, vetch, and 

 horsebean; and oats and lentils. The yields are tabulated and analyses 

 (food constituents) of all the mixtures are given. The author concludes 

 that these croi)s comi)are favorably in value with clover hay. 



Fertilizer experiments on oats, C. A. Goessmann {Massachusetts 

 Hatch. ^St((. Rpt. 18!)(>, pp. 27S-:28S). — This is a continuation of previous 

 work published in the Annual Report of the State Station for ISO! 

 (E. S. R., 7, p. 298). In a preface the author reviews his previous work 

 in this line. On 11 tenth-acre plats a uniform application per acre was 

 made of i)otash and phosphoric acid, and on 8 of the plats 45 lbs. per 

 acre of nitrogen was added in the form of nitrate of soda, sulphate of 

 ammonia, or dried blood. The plats were sown to oats. The yields are 

 tabulated and com[)ared with those in 1893. The author states that 

 the condition of the different plats has apparently not been materially 

 changed by raising soja beans. 



The comparative effect of muriate and sulphate of potash on 

 the potato crop, E. H. Jenkins (Connecticut State Sta. Rpt. 1895 .^ pp. 

 117-127\ pis. ;J). — This is a report on 1 cooiierative experiments carried 

 on in the State under the supervision of the station and 1 in coopera- 

 tion with the German Kali Works of New York on the effect of potash 

 salts on the potato crop. Nitrogen and phosphoric acid in different 

 forms and potash as sulphate or muriate were used in varying amounts. 

 The tabulated data give the yields, starch content, and analyses of 

 samples of the crops raised. 



The author states that the results reported naturally differ with the 

 character of the land, quantity of nitrogen ai)plied, weather conditions, 

 etc. ; that in general when muriate of jjotash was applied the potatoes
