Effect of humic acid and foliar fertilizer on the yield and other vegetative properties of okra

Abstract

This experiment was carried out in one of Ramadi fields, AL-Anbar province in the spring season of 2007. The aim was to study of effect of liquid humic acid and foliar fertilizer on the yield and other vegetative properties of okra. Results showed that spraying treatment with humic acid for twice significantly increased plant height, leaf width and yield by (183.5cm, 25.6cm and 1474 kg/d, respectively), while the number of leaves, leaf width and yield decreasing significantly by (24.6 leaf/plant, 22.6cm and 1298 kg/d in control, respectively).The foliar spray for twice led to increase plant height, number of leaves, leaf width and yield, significantly, which were (176.8cm, 31.1 leaf/plant, 26.6cm and 1467 kg/d, respectively), while they were significantly decreased for all the above properties in control (146.1cm, 25 leaf/plant, 21.9cm and 1281 kg/d, respectively).
