| dc.description.abstract | Nano science research has extensive applicability as nanoparticles have special features and can also be exploited in the field of Agriculture. Earlier in our lab, Silver nanoparticles (Ag NPs) have been phytosynthesized using Sandalwood leaf extract and characterized by SEM, FTIR and XRD analysis. In this study, the applicability of the phytosynthesized Ag NPs was tested on groundnut crop and a field experiment was taken up with the variety GKVK 13 in Kharif of 2018 at GKVK, Bangalore. The study reveals that Ag NP treatments significantly enhanced plant biomass and groundnut yield. The Ag NP treatments also resulted in significant suppression of late leaf spot disease severity in groundnut. The study demonstrates Ag NP induced defense priming-like response with elevation of defense enzymes (SOD, POX) and secondary metabolites such as phenolics and flavonoids in groundnut. The field experiments revealed higher pod yield (29.91%), seed yield (47.18%) and shelling per cent (25%) as compared to control. The soil from the Ag NP treated experimental plots did not show significant variation in terms of bacterial and actinomycetes populations. The changes in membrane potential in groundnut calli cells, exposed to Ag NPs, demonstrates an Ag NP induced depolarization that required extracellular Ca2+ . The phytosynthesized Ag NP showed significant inhibitory effect (LC50 986.98 ppm) against the insect pest Diamond Back Moth. The study thus demonstrates that phytosynthesized Ag NP has the potential of being used as a growth promoter and for the management of phytopathogens and pests in crops. | en_US |
