Studies conducted to evaluate the effect of number of seed pieces cut, seed size and fungicidal treatment on decay and yield of potato indicated that there was higher degree of decay in untreated seed pieces, whereas plant stand and yield was higher in Dithane-M-45 treated sets. Size of seed piece and number of cuttings did not influence the yield and yield attributes of crop. The yield was higher from whole tubers planted crop and best results were obtained from tubers of 50 g or higher weight. Extra large tubers (105 – 110 g and 140 – 150 g) planted at double spacing (40 cm) resulted in similar yield as by 50 g tubers planted 20 cm apart.
