FIELD CHOPS. 399 



into 10 plats each, witli spaces betAveen adjacent plats. The usual fer- 

 tilizers and combinations were used. The potatoes were attacked by 

 bligiit in July, and the yields, which are tabulated, were "quite light 

 on all of tlie plats." Plants on plats fertilized witli potash withstood 

 the blight best. The yields on these plats during the years of the 

 test are tabulated. 



Soil test ivith fertilizers on corn (p. 110). — A coiiperative fertilizer 

 experiment with corn was continued on the farm belonging to the 

 Ekonk Grange. Previous work in this line was published in the Annual 

 Report of the station for 1894 (E. S. R., 7, p. 571). Tabulated data are 

 given for the kind, amount, and cost of fertilizers, yield of shelled 

 corn, percentage of dry matter in shelled corn, Aveight of shelled corn jier 

 bushel, proportion of good and poor corn, and weight of stover per acre. 



A report of progress is made in experiments in green manuring with 

 different kinds of leguminous crops for tlie purpose of studying their 

 value for improving wornout, sandy lands. Owing to the dry season 

 in 180."> the results were inconclusive. So far cowpeas have given the 

 best results. 



Field experiments vrith different commercial fertilizers, C. A. 

 G0ESS3IANN [MassachmetU Hatch tSta. Ept. 1895, pp. i^.'W-^-'y.s). — The 

 results of experiments begun in 1800 (E. S. R., 7, p. 292) with dis- 

 solved bone black, South Carolina j)hosphate, Florida phosphate, Mona 

 guano, and phosphatic slag are reviewed, and the data for 1805, with 

 rye as the crop, are reported. A summary is given of the yields of 

 crops from 1800 to 1805, inclusive, and a tabulated statement of the 

 phosphoric acid applied to and removed from the field. 



The author states that the amount of phosphoric acid in the soil at 

 the close of the season in 1805 was lowest in the plat where dissolved 

 bone black was applied. 



Report of the agriculturist, W. P. Brooks {Massachusetts Hatch 

 iSta. Rpt. 1895, pp. 177-208). — Cooperative experiments with fertilizers 

 on corn were carried out on o farms in the State, and the results in 

 two cases are rej)orted, in which the yields were larger where either 

 muriate of potash or nitrate of soda were applied. 



At the station the yield of rye where barnyard manure or complete 

 commercial fertilizers were employed was increased, and wliite nuis- 

 tard sown July 31, after the rye, made the largest growth on plats 

 that had previously received applications of i)hosphates. 



In a comparison on 1 quarter-acre plats of muriate and sulphate of 

 potash as a source of potash for i)otatoes the fertilizers were api)lied 

 broadcast and in the drill. The author states that the plats receiving 

 the sulphate of potash have given the largest yield in every instance 

 except one, and the .average difference in favor of drill application 

 amounted to 22.1 ]»u. of merchantable ]»otatoes per acre. 



The difference in yield between Maine-grown seed potatoes and seed 

 grown at the station from Maine-grown seed of the year previous was 

 36.5 bu. in favor of the former.
