Abstract

A study was conducted to find out the response of four level~ each of
nitrogen (0, 100, 150 and 2()O kg/hal and phosphorus (0, 30, 60 and 90kg/ha)
and their interactions on growth and seed yield of radish cv. Japanese White.
Highest seed yield (6.25 q/ha.) was recorded with the applIcation of 150 kg N/
ha. Highest dose of nitrogen I.e. 200 kg/ha resulted In delayed flowering, less
number of branches, pods per plant and poor seed yh!ld. On the contrary, the
application of phosphorus showed no significant change In any of the characters
studied except days to 50% flowering and seed yield during 1995 and 1994,
respectively over zero phosphorus level. Seed yield was at par upto 60 kg P/ha,
however, highest dose of phosphorus (90 kg P/ha) resulted in significant decrease
In seed yit:ld. The NxP Interaction reflected significant effect on different growth
and seed yield attributes. T..e maximum seed yield of 6.65 q/ha was registered
under N150 P30 kg/ha and closely followed by N150 P60 kg/ha (6.55 q/hal.
