Abstract: The experiment was conducted at Research and Instructional Farm, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) duringkharif season of year 2010-11. The experiment was laid out in factorial randomized block design with 18 treatment combinations which were replicated three times. The treatment consisted of six genotypes of elephant foot yam viz; IGAM-1, IGAM-2, IGAM-8, NDA-2, TRC- Badama and Sree Padma which were planted at different spacing of 50 x50 cm, 60 x50 cm and 60 x 60 cm. The results revealed that the combination G4 x S3 (NDA-2) x (50 x 50 cm) recorded maximum sprouting per cent, girth of stem, canopy spread, number of cormels/plant, weight of cormels/plant (kg), corm yield (kg/plant) and total corm yield (q/ha.). The treatment combination G4 x S1 (NDA-2) x (60 x 60 cm) recorded maximum size of corm and dry matter per cent of corm. The treatment combination G2 x S3 (IGAM-2) x (50 x 50 cm) recorded maximum plant height. The maximum days to first emergence, days to 50% emergence and number of stems/plant was recorded under G5 x S1 combination (TRC-Badama) x (60 x 60 cm). The treatment combination G2 x S2 (IGAM-2) x (60 x 50 cm) recorded maximum average weight of corms and highest days to senescence was recorded under G6 x S1 combination (Sree Padma) x (60 x 60 cm).
