ABSTRACT
This study was conducted during the 2021 growing season at the Horticulture and Forestry Station in Al-Mahaweel, Babylon Governorate, to evaluate the effects of poultry waste application (at rates of 0, 5, 10, and 15 tons per hectare) and foliar fertilization with Grow Green (at concentrations of 0, 3, 6, and 9 grams per liter) on seedling growth, nutrient availability, and nitrogen (N), phosphorus (P), and potassium (K) uptake. The experiment followed a completely randomized design (CRD) with three replications. Key findings revealed that the application of poultry waste at 15 tons per hectare significantly enhanced soil-available NPK, seedling nutrient uptake, and growth parameters, including leaf number, plant height, and leaf area. However, the highest concentration of Grow Green foliar spray (9 grams per liter) demonstrated superior efficacy, producing statistically significant improvements in all measured traits compared to both control treatments and the maximum poultry waste application rate.
