Afield experimellt was carried out for three consecutive years ( 1997-1999) in upper mid hills
( 1940 mas/) to identify an appropriate spacing and date of transplanting for the late season
(March -May) caulijlov..'.!r production using a11 open pollinated variety. Four different plant
spacing (45x30 em, 45x40 em, 45x50 em and 45x60 em) and the same mtmber of
transplallting dates ( 1" week of February, 3rr1 week of February, 1" week of March and 3"1
week of March) were tested in factorial arrangements in randomized complete block design
with three replications. Among the tested plant spacing, 45x30 em between row and plants
respectively yielded the highest ( 19.63 t/ha) curd yield, which was followed by 45x40 em
spacing ( 18.5 tlha). None significant yield difference of curd yield between 111 week of
February ( 18.55 tlha) and 11
' week of March ( 18.98 t/ha) transplanting clearly demonstrates
that Kibo Giant variety of cauliflower ca11 be transplanted up to the first week of March for
late season production without loosing its genetic potelllial. Higher yield than that of
national average from the last date of transplallling i.e. 3'd week March ( 13.9 t/ha) clearly
point out a need for further testing of the dates by using the same variety. Recommendation
of closer spacing simultaneously demands a new rate of fertilizer requirement. Hence, an
investigation for appropriate dose of chemical fenilizers using the new spacing is pivotal for
the technology promotion.
