Forty five days old stecklings were transplanted on five dates of transplanting viz., 1 st October, 15 th October, 1 st November, 15 th November and 30 th November with four plant spacings viz., 60 x 60 cm, 60 x 45 cm, 60 x 30 cm and 60 x 15 cm were tested in seed crop of radish var. Pusa Chetki during rabi season of 2000–2001. The result indicated that maximum seed yield 17.49 q/ha was harvested from steckling planted on 1 st October. Among plant spacing, the closest spacing of 60 x 15 cm produced highest seed yield (17.96 q/ha). The interaction of time of planting x spacing was significant for number of pods per plant, seed yield per plant and per hectare, which indicated that 1 st October planting with close spacing 60 x 15 cm produced highest seed yield (25.59 q/ha).
