Afield experiment was executed to identify an appropriate transplanting age of seedling and
hardening effect on curd yield in spring season cauliflower production. The experiment was
conducted for two consecutive years at the central fann of Agriculture Research Station,
Pakhribas. The design was RCB in 3x2 factorial arrangemelll with three replications. Three
ages of seedlings (35, 45 and 55 days after sowing) with and without hardening were tested.
Marketable curd yield of cauliflower were found highly significant on ages (p<.05),
hardening (p<.OOI) and interaction (p<.05) of these factors. The highest yield (13.85 t/lta)
was recorded from the hardened seedlings of 45 days old. It can be concluded from the
experiment that hardening has the positive contribution to curd yield and seedlings of 45
days are appropriate for transplanting during spring season production while using an open
pollinated variety.
