An experiment was carried out in the Grain Technology Laboratory, Department of Crops, Faculty of Agriculture - Omar Al-Mukhtar University, during the 2023 AD season, with a completely random design, to study the effect of soaking seeds and spraying seedlings with some Nanoparticles) NPs( (iron, manganese, and copper Nano oxides), Nano-Phosphorus, and Biota agro, and their reflection in some plant growth indicators. Mung beans (Vigna radiata L.) at a concentration of 1 cm/L of one M solution for 10 minutes, then planted in pots with a capacity of 3 kg, with 10 seeds per pot through 3 observations of each treatment. The data showed: • A significant response of mung bean plants to the application of nanoparticles (iron, manganese and copper oxides), nano phosphorus and beta agro was observed in some growth indicators (plant weight, plant height, leaf area, crop growth rate and leaf specific gravity). • Nano phosphorus outperformed by giving the plant the highest weight and leaf area. The crop growth rate reached (3.780 g, 19.2 cm2, 0.506 g/day, respectively) compared to the control treatment. Also, both iron oxide and nano phosphorus outperformed the rest of the treatments under study by giving the highest leaf specific weight. (0.1493, (0.0993) respectively. • Biota Agro excelled in giving the highest plant height, reaching 23 cm, followed by manganese oxide, which reached 21 cm, compared to the control treatment, which decreased to 8.50 cm Keywords: soaking seeds, mung bean growth, Nano-fine fertilizers, Biota agro, Nanoparticles(NPs).
