The Efficiency of Bacterial Bio-Fertilization and Schanginia Aegyptiaca (Egyptian Seablite (Waste in Reducing Mineral Fertilizers and in the Growth and Yield of Cabbage

This study investigates environmentally friendly fertilization strategies to enhance nutrient availability and reduce the use of chemical fertilizers in calcareous soils. It explores the effects of biofertilizers (Azotobacter, Pseudomonas), Changinia aegyptiaca plant residues, and phosphorus levels on cabbage growth and nutrient uptake in sandy loam soils. The results show significant increases in plant height (45 cm), number of leaves (37 leaves), head yield (997.3 g/plant), and nitrogen, phosphorus, and potassium concentrations (20.60, 8.01, and 22.96 g/kg, respectively) with the combined treatments. Standard growth-at-maturity methods were used for analysis. The combination of biofertilizers, phosphorus, and Changinia plant residues enhances cabbage productivity and fertilization efficiency, suggesting a way to reduce reliance on chemical fertilizers and improve soil health.
