Invitro Efficacy of Biosynthesized Silver Nanoparticles on Trigonella foenum-graecum L. Seed Germination and Growth

Nanoparticles have been suggested as a relatively new hope in agriculture area as a biofertilizer to make agriculture more sustainable. The purpose of this study was to compare effect of biologically synthesized silver nanoparticles on growth and development of plant during germination as well as seedling and vegetative period. Fertilizers are an important key factor for the production of any crop in both developed and developing countries. Nanoparticles as biofertilizer are a relatively new approach in agriculture area and it has had many promising results. It has potential contribution in slow release of fertilizers. In the present investigation, Silver nanoparticles were biologically synthesized using Aspergillus terreus and Aspergillus niger strains collected from culture center in aseptic conditions. It was observed that low concentrations of Ag nanoparticles being 20 ppm, 40 ppm and 60 ppm showed better growth than higher concentrations like 80 ppm and 100 ppm. The plants treated with low concentrations of Ag nanoparticle showed better growth than the control. So, to conclude there is significant difference in the growth of plants which had been treated with Ag nanoparticle and those without. (author)
