Seed pieces from large and small tubers. 



Notes and tabulated ihita are given Inr an experiment in wliieli fer 

 tili/.ers were ai>plied above ami l>eIow seetl jjotatoes (»f the Early liose 

 and lieauty of lleltroii \arieties eultivated liy tlie trench and ridge 

 systems. 



The results of an exiieriment are tabulated and discussed in which 

 cotton-seed meal, nitrate of s(»da. superpliosjiliate. kainit. and muriate 

 of potash, used singly and in dill'ncnt combinations, were conipaictl 

 with stable manure and witli no manure on \uh\v, sandy soil. 



Tlie following is a summary of the various experiments: 



(1) The most promising new varieties of )>otatoes are l>rowiiell No. 

 31, Early Delaware, Ilowe Premium, Late Puritan, liural New Yorker 

 No. 2, and Seneca Beauty. Southern seed gave larger yiehls than East- 

 ern or \\'estern seed. There was very little ditference in the yields from 

 Eastern and NN'estern seed. 



(2) The total yield increases in proportion to the size of the seed 

 piece.
