Summary

Experiments conducted on saline-sodic soils during 1972 and 1973 showed that delay in transplanting medium-duration dwarf high-yielding varieties like Jaya beyond 20 July caused substantial reductions in grain yield, but there was no depression in yield of such varieties even if 55 day old seedlings were used for transplanting at normal times. Older seedlings gave very high yields compared with younger counterparts at late transplantings. Fifty-five day old seedlings took about two weeks less to mature compared with ones planted when 25 days old.
