| Abstract | ||||
| Onion (Allium cepa L.) is an important crop in Egypt that requires fertilizer to improve yield and soil health in low-organic-matter soils. At Damanhour University, experiment farm at Agriculture faculty, this study assessed the effects of mineral fertilizer and bio-fertilizers (Nitrobeine, Phosphorene) combinations on soil fertility, growth, and nutrient content of green onions (Allium fistulosum L.) in loamy sand soil during the 2022–2023 and 2023–2024 seasons. Using a Completely Randomized Design with three replicates, treatments included control (CK), NPK, Nitrobeine (bioN), Phosphorene (bioP), mixed bio-fertilizers (bioN-P), NPK&bioN, NPK&bioP, NPK&bioN-P, 0.5NPK&bioN-P, and 0.75NPK&bioN-P. Vegetative growth characteristics, plant chlorophyll content (SPAD), plant and soil nutrients contents were measured. Fresh weight of the plant (33.03 g), dry stem weight (8.97 g), plant content of N (3.18%), K (3.43%), soil content of N (26.95 ppm), P (11.05 ppm), and K (119.25 ppm) were all maximized by the NPK&bioN-P treatments. Similar result was achieved with fresh weight (32.23 g) and root/leaf growth with application of the 0.5NPK&bioN-P treatments, suggesting that yield was maintained at 50% lower NPK when combined with bio-fertilizers. While soil P grew (6.93, 14.67 and 13.60% consecutively) with bio-fertilizers-only treatments (bioN, bioP, and bioN-P). For increasing onion productivity in Egypt, integrated nutrition management provides a sustainable approach, especially for NPK&bioN-P and 0.5NPK&bioN-P. | ||||
