This
research was carried out to determine the effects of nitrogen application times
on the morphology, yield quality
characters of safflower under Van ecological conditions between 1997 and 1998.
In the study, amonium nitrate (33%) were used as fertilizer. 12 kg N/da of each
fertilizer was applied in the one application time (all in sowing), in the two
application times (in sowing and in periyod of branching-stem elongation ), and
in the three application times (in sowing, in period of branching-stem
elongation and in period of setting of head-flowering).
The effects of application times were found significant
(P<0.01) especially on the plant height, branch number , seed yield, crude
oil content and crude oil yield in both experimental years. While the highest
seed yield was obtained in three application times in 1997 and 1998 years as
206.59 and 232.12 kg/da respectively. On the other hand, crude oil content and
crude oil yield was obtained in three application times increased in both years
26.26 and 28.16% oil content; 54.41 and 65.35 kg/da oil yield respectively.
