(1) The average yield from potato seed pieces of equal size, was 15.55 bushels per acre, higher when select tubers were used for seed than when "culls" were used for seed. Page 103.
(2) Thus the present bulletin furnishes quantitative data, supporting the theory that the use of culls for seed, will cause a variety of potatoes to "run out", the effect being measurable in the first generation. Page 103.
(3) The present Bulletin enforces the conclusion of Bulletin No. 140, namely yield per acre definitely is influenced to vary definitely with increase in size of seedpiece. Page 107.
(4) For the highest yield of the finest tubers, use select seed potatoes. Page 108.
