EXPERIMENT STATION RECORD. 



Buddinf/ (i)p. 12-19). — Seed tubers about the size of liens' eggs x)laced 

 steui end down on racks held in tiers in a framework are kept iu a moder- 

 ately warm (60 to 75° F.) and fjiirly lighted room for 4 to G weeks. 

 The racks are figured and described. Thick, firm buds J to 1 in. long 

 and :| to f in. in diameter will form which, when ready for planting, 

 may be kept nninjured for days or weeks by lowering the temperature. 



On March 20, 2 bu. of the Early Rose variety, each containing 311 

 potatoes of an average weight of about 3 oz., were taken from the bin; 

 one bushel was kept in a bag in a cold cellar; the other was placed iu a 

 tray under favorable conditions for budding. May 1, on a light, sandy 

 loam, manured with commercial fertilizers, f applied broadcast and J 

 in the drill, the potatoes were jjlanted in 8 rows at distances of 15 iu. 

 between sets. Each tuber was cut in two before planting. 



On July 29, 10 ft. of each row was harvested, and on August 20 

 the remainder of the crop. The following table contains the yield per 

 acre, the gain from the budding method and the increased growth 

 between the two dates of harvesting:

Notes are given on potato culture on the island of Jersey. The 

 authors state that w^here large seed tubers are used sprouting is pref- 

 erable to budding. 



Potatoes, fertilizer experiments, W. J. Green and H. O. McFad- 

 DEN {Ohio Sta. Bui. Go, pp. 151-159). — The trial plats are of jL. acre at 

 the central station and .,\ acre at the substations. Sujjerphosphate, 

 muriate of potash, nitrate of soda, bran, linseed meal, dried blood, 

 sulphate of ammonia, bone meal, acid phosphate, basic slag, and barn- 

 yard manure, alone or combined in various proportions, were applied 

 on 18 plats; of these, 8 plats received the same quantity of nitrogen, 

 phosphoric acid, and potash, but in different forms. Thirteen plats 

 were without fertilizers. 



The yields are tabulated. In conclusion the authors say: 



"In the use of fertilizers the lowest cost per bushel of increase in crop has been 

 attained iu the use of superphosphate alone, but the greatest gain per acre has been 

 with 1,100 lbs. per acre of fertilizer coiitainiug phosphoric acid, nitrogen, and potash. 



"Muriate of potash and uitrate of soda when used alone have not given a profitable 

 increase, but have proved beneficial iu connection with superphosphate. 



"Phosphoric acid seems to have been the controlling element iji an increase in the 

 potato crop in all of our experiments,"
