EXPERIMENT STATION RECORD. 



The average results for the 2 years show that the largest total crop 

 aud the largest yield of large tubers was produced wheu the supply of 

 potash was half sulphate aud half muriate. The standard application 

 of muriate of potash gave a better average yield of total product of 

 large aud small tubers than au application containing double the amount 

 of potash. The tests with different amounts of phosphoric acid resulted 

 in the smallest average yield from the standard application, the next 

 largest from the use of 3 times the amount of phosphoric acid furnished 

 in the standard fertilizer, and the largest yield — an increase of 15.9.5 bu. 

 per acre of marketable potatoes over the standard application — from a 

 fertilizer which contained twice that amount of phosphoric acid. The 

 amount of phosphoric acid which proved the most effective cost $6.29 

 more per acre in 1897 than the amount in the standard application. 

 The average results iu the comparison of nitrate of soda and dried 

 blood as carriers of nitrogen show that nitrate of soda was most effect- 

 ive, followed by dried blood, and au application of half of each in the 

 order mentioned. The difference in the average of the crops of the 

 nitrogen plats was not great, the extremes in the marketable tubers being 

 165.35 and 173.4 bu. per acre. 



Trials with fish guano for sugar beets, P. Hansson (Meddel. K. 

 Landibr. Styr., 1897, JVb. 42, pp. 149, 150). — Fish guano and nitrate of 

 soda were applied in corresponding quantities on 6 plats, 3 of which 

 received fish guano and 3 nitrate of soda. On clay humus the relation 

 of the effect of nitrate of soda to that of fish guano was as 100 to 80; 

 on moist humus, as 100 to 90, and on dry, porous, and sandy humus as 

 100 to 120. — F. w. WOLL. 



Fish guano vs. nitrate of soda for sugar beets and for barley, 

 C. O. Hammaegeen (Meddel. K. Landtbr. Styr., 1897, No. 42, pp. 145, 

 146). — Comparative experiments with fish guano and nitrate of soda 

 for sugar beets and for barley were made on eighth-acre plats. The 

 results obtained are given in the table :

Report of the agriculturist, H. E. Stockbridge (Florida Sta. Bpt. lS9S,pp. 11- 

 21). — In this report the station farm is described and rontemplated experiments are 

 outlined. Bulletin No. 44 of the station is reviewed (E. S. R., 10, p. 347). Directions
