Effects of planting pattern on yield, its components, oil contain and some important agronomic traits of Safflower (Carthamus tinctorius L.) in dry land conditions

In order to Effects of planting arrangement on yield, its components and oil contain for new cultivar of Safflower in dry land condition, an experiment was conducted as factorial in a randomized complete block design with three replication in Ilam, Iran in 2008-2009 growing season. The factors consisted of three row spacing (30, 40 and 50 cm) and three plant spacing (10, 15 and 20 cm). The result showed that row spacing were significant on grain yield, head per plant, seed per head, 1000 weight seed, harvest index, biologic yield, plant height and oil yield. With decrease row spacing, grain yield (1971 kg.ha-1), head per plant (15.5), 1000 weight seed (31.7 g), harvest index (40.04), biologic yield (4922 kg.ha-1), plant height (94.03 cm) and oil yield (542 kg.ha-1 ) increased. The highest (1971 kg.ha-1) and lowest (1035 kg.ha-1) grain yield obtained from 30 and 50 cm respectively. The plant spacing were significant on grain yield, head per plant, seed per head, 1000 weight seed, harvest index, biologic yield, plant height and oil yield. With decrease row spacing, grain yield (1730 kg.ha-1), head per plant (16), 1000 weight seed (33.4g), harvest index (37.5), biologic yield (kg.ha-1), plant height (92.2 cm) and oil yield (482 kg.ha-1) increased. The highest (1730 kg.ha-1) and lowest (1275 kg.ha-1) grain yield obtained from 10 and 20 cm respectively. According to the Results the highest grain yield obtained, 30 cm row spacing and 10 cm plant spacing. Correlation coefficients showed that head per plant, 1000 weight seed, harvest index, biologic yield and plant height significant positive correlation with grain yield. Therefore this Planting pattern (30×10) in a local of Ilam and under similar conditions could be recommended.
