![]() Our findings showed that homeostatic instability under highest levels of NH 4 ⁺, especially in the plants cultivated without Si in the nutritive solution resulted in decreased shoots and roots dry matter production. ![]() In addition, shoot and root increased as higher levels of NH 4 ⁺ in the nutrient solution. Our results indicate that in presence of Si both and in shoots and roots increased significantly and reaching its highest value at 15 mmol L − 1 of NH 4 ⁺ in the nutrient solution, while shoot remained stable, in roots increased with NH 4 ⁺ concentrations of 22.5 and 30 mmol L − 1, respectively. The experimental design was a randomized block design based on a 5 × 2 factorial scheme with four replicates. Early Wonder in the absence and presence (2 mmol L − 1 ) of Si. We conducted a hydroponic experiment to evaluate the effects of five concentrations of ammonium (1, 7.5, 15, 22.5, and 30 mmol L − 1 ) on C:N:P stoichiometry and yield of sugar beet cv. In this study, we investigated the effects of different NH 4 ⁺ concentration on the C:N:P stoichiometry and yield of sugar beet grown under hydroponic conditions, and examined whether the application of Si can alleviate the detrimental effects caused by toxic levels of NH 4 ⁺. However, underlying studies on the effects of ammonia toxicity on C:N:P stoichiometric homeostasis and the role of Si in these stoichiometric ratios are lacking. In this scenario of NH 4 ⁺ stress, it is important to use strategies to mitigate this toxicity, and the use of silicon (Si) has promoted promising results. Most plants develop severe toxicity symptoms when grown on NH 4 ⁺ as the sole nitrogen source, resulting in physiological and nutritional disturbances that slow vegetable growth.
