A field experiment was carried out in 1997 and 1998 at Ginger Research Program Kapurkot, Salyan (1480 masl) to find out the cost effective seed rhizome size and spacing for planting to get the maximum yield. Both the factors, spacing and seed size caused the significant difference on crop yield. Economic analysis for marginal rate of return indicated that planting rhizomes 30 cm apart between and within row was found appropriate spacing for mid-hill conditions. Seed to yield ratio was found decreasing with the increase in seed size. The highest yield (41.8 t/ha)  was obtained from the large size seed rhizomes (90 gm), whereas marginal rate of return was minimum (44.7%) when planted large size rhizomes. The result clearly revealed that spacing 30 cm X 30 cm and seed size of 60 gm gave the highest marginal rate of return (79.6%). Therefore, the seed rate of ginger for Salyan cultivar, 6.0 t/ha was found cost effective for mid-hill conditions.
