| Abstract | ||
| In order to determine the best sowing date and plant density (space between plants) of okra (Abelmoschus esculentus), a field experiment was conducted in two years (2002-2003) at the Iranshahr Agricultural Research Station. A split plot design in randomized complete block with four replications was used. Four sowing dates (4 and 19 February, 6 and 21 March) were considered as the main plots, and three plant densities (30, 50 and 70 cm plant spacing) as the sub plots. The results indicated significant differences among plant densities for number of capsules/ plant, single capsule weight, capsule length and plant height and fruit yield. The treatment of 30 cm plant spacing, with 12.6 tha-1, had the highest fruit yield. The effect of sowing date was also significant, and the highest fruit yield with 12.9 tha-1 obtained from the sowing date of 6 March. Interaction effects of sowing date and density were significant. The treatment of 30 cm plant spacing in 6 March sowing date with 17.5 tha-1 fruit yield had the highest fruit yield, therefore, sowing in 6 march and 30 cm plant spacing are recommended for okra production in Iranshahr. | ||
