The present study deal with the effect of different quantities of Manganese Oxide Nanoparticles on the growth of Ladies finger Abelmoschus esculentus. Manganese oxide nanoparticles were synthesized by the co-precipitation method and characterized by using UV-V is spectroscopy, SEM, EDAX, FTIR, and XRD. Pot culture studies on different quantities of manganese oxide nanoparticles such as 100, 200,300, 400 and 500 mg for treatments T₀ (control) T₁, T₂, T₃, T₄, T₅ respectively on the growth of Lady’s finger Abelmoschus esculentus were conducted. Growth characteristics such as seed germination efficiency, shoot length, root length, total fresh weight, total dry weight, leaf area index and vigour index were measured on 30 days. The UV-Visible absorption spectrum of manganese oxide nanoparticles was confirmed from the peak at 333 nm. SEM image of manganese oxide nanoparticles was observed as a saucer in shape. EDAX spectrum recorded three peaks located between 0.62 KeV 5.9 KeV. The XRD diffraction peaks of MnO nanoparticles are indexed as 041,142, 123, 281, 163,
100,200. The FTIR spectrum was analyzed in the range of 500-4000 cm-1 spectral bands. Germination efficiency of the Lady’s finger Abelmoschus esculentus was higher in T₃ (300 mg) and lower in T₅ (500mg). Shoot length, root length, fresh weight, dry weight, leaf area and vigour index of Lady’s finger Abelmoschus esculentus was higher in T₃.
