The maximum size of cuttings for plantings seemsto be about three-fourths pound, owing to the fact that larger piecesare frequently attacked by decay after they are planted. This istrue more especially when the roots have been injured or subjectedto unfavorable weather. Large top sections are preferable to largecenter sections when yams are desired for market. The roots pro-duced by the former, though fewer in number, are much larger andtherefore always sell more readily than those produced by thelatter. W

The roots pro-duced by the former, though fewer in number, are much larger andtherefore always sell more readily than those produced by thelatter. When roots are desired for planting the following year,center sections weighing about three-fourths pound should be pre-ferred over top pieces or crowns. A number of yams develop alongthe margin of the cut area of these sections and these in turn developinto small or medium-sized roots. The formation of three to sevenyams on one seed piece greatly increases the number of crowns for Bui. 27, Porto Rico Agr. Expt. Station. Plate. Fig. I.—Variety Test of Yams, Ridge Culture, Porto Rico
