yield and yield components of two safflower varieties, an experiment was
conducted at Agriculture Research Station of Isfahan Kabotar Abad in 2004.
A split plot layout within randomized complete block design with three
replications was used in the experimentation. Eight sowing dates were
in the main plots, consist March 6, March 21, April 6, April 21, May 6,
May 21, June 6 and June 21 and two varieties (Isfahan 14 and I.L111) were
in the sub plots. The results showed that the number of seed per capitulum
and seed yield were decreased significantly as the sowings dates were
delayed. The Isfahan 14 variety in comparison with I.L111 produced more
fertile capitulum in square meter and also, respectively seed per capitulum.
The second sowing date (March 21) produced the highest seed yield (2306.2
kg ha-1), whereas the 7th sowing date (June 6) produced the
lowest seed yield (622 kg ha-1). The effect of variety for
seed yield was not significant. Farmers in the Kabotar Abad of Isfahan
and in other areas with similar conditions are recommended to plant the
Isfahan 14 variety on March 21.]]>Adisarwanto, A. and R. Knight, 199748116118Bagheri, A., B. Yazdani-Samadi, M. Taeb and M.R.
