Description A field study was conducted during rabi 1989-
90 at the Horticultural Garden, College of Agriculture,
Rajendranagar, Hyderabad to study the performance of
coriander cultivars at different dates of sowing under
Hyderabad conditions. The treatments consisted a combination
· of three dates of sowing (20th October, 4th
November and 19th November) and six cultivars (Local,
co-1, co-2, cs-2 ·, cs-4 and cs-6) • The experiment was.
laid out in a split plot design, replicated four times.
Dates of sowing and varieties effected growth,
flowering, yield attributes, uptake of N, P and K, seed
and essential oil yield significantly. Early sowing
i.e., 20th October resulted in maximum pl~t height,
dry matter production,_1 branches plant , umbels
plant , umbelets umbel , uptake of N, P and K, seed
and essential oil yield. Sowing on 19th November
resulted in early flowering, SO per cent flowering and
minimum flowering duration. Delayed flowering and
maturity were recorded with early sowing followed by
4th November sowing.
Among . different cultivars tested, cs-4 recorded
more plant height, . branches plant , dry matter
production, days for flowering, SO per c~it flowering,
durat!£n of flowering, umJ;>els plant _1 umbelets
umbel , 1000 seed weight, mericarps plant , uptake of
N, P and K, seed and essential oil yield followed by
co-2. The least performance was noticed in local
cul ti var.
Significant interaction between sowing dates
and varieties was noticed in mericarps plant , seed
and essential oil yield. cs-4 recorded maximum essential
2il yield in three dates of sowing, more mericarps
plant and seed yield with two dates of sow.'j.ng (·i.e.,
20th October, .. 4th November) followed by C0-2. Whereas
in late sowing (19th November) reverse trend .was
noticed.
All the characters included .in the study exerted
significant linear relationship with the seed as
well as essential oil yield. Character association
among the different characters was also found positively
significant.
Uptake of K and N by seed, N and K by stem,
mericraps plant , · duration of flowering, umbelets
umbel , plant height, umbels plant , branches plant
and days for flowering exerted a positive direct effect
pn ·seed yield, whereas dry weight of seed and stem,
days for 50 per ·cent flowering, uptake of P by stem and ·
seed and ' 1000 . seed weight exerted a negative direct
effect on seed yield. All the characters other than
dry · weight of seed and stem, days 'to 50 pe7 cent flowering,
umbels plant and 1000 seed weight exerted
positive direct effect on essential oil yield.
