Abstract: The present study aimed at the effect of different quantities of magnesium oxide nanoparticles on the growth of Black gram Vigna mungo. MgO nanoparticles were synthesized and characterized using UV-VIS,SEM, EDAX, XRD, and FTIR.Pot culture studies on different quantities of magnesium nanoparticles such as 100, 200, 300, 400 and 500mg for treatments T0 (control) T1, T2, T3, T4, and T5 respectively on the growth of black gram Vigna mungo were carried out.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 for 30 days. The UV-Visible absorption spectra finding demonstrates that magnesium oxide nanoparticles were measured in wavelength within the range 300 to 600 and exhibits a strong absorption band at 550nm.SEM image of magnesium oxide nanoparticles was observed as clumped in shape. EDAX spectrum recorded on the magnesium oxide nanoparticles is shown as the peaks were located on the spectrum at 1.2 KeV. The FTIR spectrum of magnesium oxide nanoparticles were analyzed in the range of 400-4000cm-1 and spectral bands and functional groups are alcohol, alkane, carbon-di-oxide, anhydride, and sulfonate. The chemical composition of magnesium oxide nanoparticles was analyzed by XRD and the diffraction peaks are indexed as 9.4?(110), 36.82?(351), 42.81?(123), 62.14?(233),74.52?(214),78.42?(352.Germination efficiency of the black gram Vigna mungo was higher in T2(200mg) and lower in T1(100mg). Shoot and root length, fresh weight and dry weight, leaf area and vigour index of black gram were higher in T4.
