Abstract:
Green synthesis of metal nanoparticles is sprouting as a new path of research in nanotechnology. In the present investigation, zinc nanoparticles were synthesized from the leaf extract of Senna auriculata. The present study is focused on application of zinc nanoparticles to peanut pot-culture for evaluation of soil micro-biota, soil enzyme activities, and physiological growth parameters of peanut plants. The zinc nanoparticles were characterized using Ultraviolet-Visible spectrophotometer, Inductively coupled plasma optical emission spectrophotometer, Fourier transform infrared spectrometer, Particle size analyzer, X-ray diffractometer, Scanning, and Transmission electron microscope. The optical absorption spectrum of zinc nanoparticles showed an absorbance peak around 328 nm, confirming the formation of zinc nanoparticles. The zinc nanoparticles were observed to be poly-dispersed and spherical shaped with an average size of about 22 nm and zeta potential of 80 mV. The synthesized zinc nanoparticles were applied to the peanut pot-culture in 3 different treatments, by maintaining the controls. Enhanced microbial population, and soil enzyme activities were observed along with the induced growth of peanut plants, when compared to the controls. Among the 3 treatments, treatment-1, application of 15 ml of sample solution (zinc nanoparticles), showed good results
