Synthesis and Characterization of Magnesium Doped Ferric Sulphate Nanoparticles (Mg-Fe2SO3 NPs) for Agriculture Applications

The present study aimed to synthesize the magnesium doped ferric sulphate nanoparticles (Mg-Fe2SO3 NPs) and investigate their seed germination efficacy. Mg-Fe2SO3 NPs were prepared by a simple cost-effective method subjected characterization. X-ray Diffraction (XRD) spectrum revealed crystalline nature of with an average crystallite size 36.41 nm. field emission scanning electron microscope (FESEM) image displayed agglomeration shape grains appeared like starfish which has limbs grown from common cluster. energy dispersive spectroscopy (EDS) demonstrated existence C (10.5%), O (49.14%), Fe (26.67%), Mg (0.78%) S (13.35%) elements in NPs. It also absence impurities synthesized Through Fourier transform infrared (FTIR), showed characteristic peaks at 615.29cm-1, 1130.29cm-1, 1400.32 cm-1and 1633.71cm-1 corresponded Fe-O, C-N, O-H N-H vibration respectively. Further, that treatment caused significant increase seedling growth cowpea (Vigna unguiculata) seeds compared untreated samples.
