| Abstract | ||
| This experiment was conducted in a private field / Karbala Governorate during 2009-2010 growing season on Okra plant (Hibiscus esculentus L.) Local cultivar. The aim of the experiment was to study the effect of spraying organic liquid fertilizer (Humi Max) at different concentrations and number of sprays and their interaction on growth and yield of Okra. The experiment comprised of 12 treatments; four concentrations (0, 4, 8and12) ml.L-1 of organic liquid fertilizer (Humi Max) and three sprays (one spray, two sprays and three sprays). The experiment was carried out using Randomized Complete Block Design (R.C.B.D.) with three replications. Variations between the means were tested according to (Duncan's Multiple Range Test) at 0.05. Results showed that spraying with organic liquid fertilizer or increasing number of sprays improved vegetative growth (plant height, total vegetative dry weight) and crop yield (number of fruits per plant, weight of single fruit, plant yield and total yield). Higher concentration and more number of sprays showed better effect. The interaction between the two variables was significant. Plants that sprayed three times with concentration 12 ml.L-1 of the organic liquid fertilizer gave the highest values for all studied characteristics. The figures were (160.55 cm.plant-1 , 61.43 g.plant-1 , 82.94 fruit.plant-1 , 4.85 g , 402.25 g.plant-1 and 25.81 t.ha-1) for experiment period successively. | ||
