Response of Orange Seedlings to Soil Addition of Some Organic Wastes, Vermicomposting Extract and Foliar Nutrient Amino-F24

Abstract

An experiment was carried out in a shaded private nursery located in Awfi, Babylon Province, from October 1, 2023, to June 1, 2024, to investigate the one-year growth response of orange seedlings. The experiment was based on three experimental factors. The first factor included soil application of organic fertilizers at three levels; the control, poultry manure at 500 g L⁻¹ and cow manure at 500 g L⁻¹and. The second factor was the application of vermicompost extract at two levels via soil and control, 10 ml L⁻¹. The third factor consisted of foliar spraying of AMINO F24 at three levels; the control, 5 ml L⁻¹, and 10 ml L⁻¹. The experiment was laid out in a Randomized Complete Block Design with three replications. The data were analyzed using Genstat 2010 software, and the Least Significant Difference at a 5% level was used for mean comparison. It was done to detect the interaction or main effect of factors. The control or untreated plants exhibited the lowest values. On the other hand, control plants showed the lowest values in most studied parameters.
