In
this study, it was aimed to determine the problems being faced with in case of
late harvesting time of safflower (Carthamus
tinctorius L.). The trial was conducted in production area of Agricultural
Faculty of Yüzüncü Yıl Univercity in 1997 and 1998. The safflower
varieties (5-118, 5-154) were placed in the main plots and the harvest times (30
September, 15 October, 30 October and 15 November) were placed in the subplots
of trial which was made according to split plots of randomized blocks by three
replicates.
As
a result of the study, while significant differences (P<0.01) were found
between varieties in terms of crude oil rate in 1997 and crude oil yield in
1998, seed yield were significant in two experiment years (P<0.01).
Concerning harvesting times, it was monitored that the result obtained from the
years of 1997 and 1998 were parallel to each other and differences among
characteristics tested were obtained significant (P<0.01), except 1000 seed
weight. The highest oil yield (39.6 kg/da) was obtained on 15th
November and seed yield (143.6 kg/da) was obtained on 30th September
and the lowest oil and seed yields (33.7 kg/da and 133.9 kg/da) were found on 15th
November in the first year. In the second year of the experiment, the highest
oil and seed yields (39.1kg/da and 139.5 kg/da) were found on 30th September
and the lowest oil and seed yields (36.0 kg/da and 133.6 kg/da ) were monitored
on 15th November. On the other hand, in the late harvesting time;
while defect head and seed number increased, seed and crude oil yield decreased.
