| Abstract | ||
| An experiment was carried out in the lath- house, Department of Horticulture and Land scape design Faculty of Agriculture, University Kufa during winter season of 2016 to verify the effect of growth medium and spray of organic residues extract on growth and flowering of Petunia plant , Randomized Complete Block Design using two factors, first included three levels of peatmoss (0,10 and 20 % of soil volume vv) and second was spray of organic residues extract at four concentrations (0,2 ,4 and 6 ml.L-1) in three replicates. Each treatment represented by three pots of 20cm in diameter and 16cm height at2L volumes. Results showed that using growth medium supplemented with peatmoss at level 20 % vv resulted in a significant increases in growth and flowering characteristics . Number of leaves per plant total, leaf area, number and length of branches, dry weight of vegetative part, number of flowers per plant and flower diameter were increased in this treatment. Spraying of organic residues extract at a concentration of 4ml.L-1 affected plant growth, flowering and root characteristics (number of leaves per plant, branch length dry weight of vegetative part ,number of flowers per plant, and length of root system .Interaction was significant where treatment of using peatmoss at level of 20%vv and spray with organic residues extract at a concentration of 4ml. L-1 increased number of leaves per plant and total leaf area(119.7 leaf.plant-1and1220.3cm2)compared to control treatment where the lowest values (37.8 leaf.plant-1and 527.2cm2respectively) Interaction treatment of growth medium supplemented with 20% vv of peatmoss and spray plants with organic residues extract at a concentration of 2ml.L-1increaed number of flowers and flower diameter (212.7 flower.plant-1 and 8.12cm) compared to control treatment (68.4 flower plant-1 and 4.74cm respectively ). | ||
