Present experimentation was done to study
the effect of ZnO-SnO2 composite on different morphological parameters of Black
gram. In this work, we have synthesized ZnO-SnO2 nanocomposite by Chemical
co-precipitation method and characterized it using X-ray diffraction
spectrograph, UV-visible absorption spectroscopy, scanning electron microscope
and Transmission electron microscope. The particle size of synthesized
nanocomposite material lies between 25.75 nm to 39.16 nm. The synthesized
nanocomposite exhibited needle shaped morphology and showed maximum absorbance
at 355 nm of wavelength. For studying the effect of synthesized nanocomposite
material on morphological parameters of Black gram, healthy and presoaked seeds
of Black gram were treated with three different concentration of ZnO-SnO2
composite (i.e. 20, 40, and 60%). Control was also maintained for each set.
Black gram belongs to family Fabaceae and is commonly used as a food for protein
and other nutritive substances. Black gram is also used as green manure for
agricultural practices. During the field observation a significant effects have
been observed on various morphological parameters. A reduction in germination
and survival percentages were also observed in treated sets.
