Abstract
The experiment was conducted at the vegetable research farm, College of Agricultural Engineering Sciences, University of Duhok, Iraq, in the growing season (2018) to study the effect of seaweed extract at four concentrations (0, 0.5, 1.0, and 1.5 ml/L) and plant spacing at three levels (30, 45 and 60 cm) on growth and yield of two eggplant (Solanum melongena L.) cultivars. The seaweed extract (Tecamin algae) sprayed at three times during growing season, 15 days between each spraying and another. The experiment were designed in a factorial experiment within Split-Split-Plot Design in (RCBD), with three replication. The results showed that the seaweed extract at concentration (1 ml.l-1) significantly increases leaf area (cm2), leaf chlorophyll content, average fruit weight, plant yield (Kg.plant-1) and total yield (ton.ha-1) compared with control plants, but not affected on plant height. Plant spacing at level (30 cm) significantly increased plant height and total yield, whereas at level (60 cm) significantly improved leaf area, chlorophyll content in leave and plant yield. Also, the Kyme cultivar significantly affected in average fruit weight, plant yield and total yield, while Anamur RZ cultivars increased plant height. The binary and triple interaction revealed that the combination between Kyme cultivars, plant spacing at level (60 cm) and seaweed extract at level (1 ml.l-1) significantly increased almost all characteristics.
