This study, conducted at Ege University, Odemis Vocational School, aimed to investigate the influence of poultry manure applications on the nutrient, sucrose, fructose, and glucose content of second crop onions. In this research, three onion varieties (Burgaz, Snow White, Champion), three different doses of poultry manure (20, 40, 60 t ha−1), and mineral fertilizer were employed. An unfertilized plot was employed as the control. The experiment was designed using a split-split plot arrangement and replicated three times. The analysis comprised the assessment of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) contents in samples collected from both onion leaves and bulbs. In addition, sucrose, fructose, and glucose levels in the bulb were determined. The Snow White variety contains the highest level of fructose, sucrose, and glucose compared to other varieties. In the exploration of the impact of macro-micro element contents in bulbs, the Champion variety exhibited significantly higher levels of N, Ca, Fe, and Cu compared to other varieties. Additionally, P, K, and Na contents were significantly higher in Champion and Snow White varieties compared to Burgaz bulbs. The difference between the applications of these nutrients was insignificant except for N, P, Na, and Fe. The Nitrogen, Potassium, Sodium, and Iron contents of soils were the lowest control, while the highest dose application had the highest value at 60 t ha−1 dose. The difference among the applications in these nutrients was significant except for Mg and Cu. It may be recommended to use 40 t ha-1 dose in onion cultivation.
