Cow dung extract mediated green synthesis of zinc oxide nanoparticles for agricultural applications

Abstract

In the present study, zinc oxide nanoparticles (ZnO) were synthesized using cow dung extract to apply sustainable agriculture from rural resources. Studies on their antibacterial potential against E. coli DH 5 alpha indicated lower antimicrobial activities than the bulk Zn and commercial Zn nanoparticles. Compared with control and commercial ZnO nanoparticles, the maximum seed germination, root length, and shoot length were observed after the priming of synthesized ZnO NPs. This study suggests that ZnO may significantly increase seed germination and have lower antimicrobial potential. Further, the lower in-vitro cellular leakage and reactive oxygen species (ROS) production provided new hope for using cow dung extract mediated nanoparticles for agricultural and industrial applications.

Green Horizons: Navigating the Future of Agriculture through Sustainable Practices

“…The use of nanotechnology, offering solutions from nanofertilizers to disease management tools [63][64][65][66][67][68][69][70][71][72][73][74], marks a significant technological frontier in agriculture, promising to increase productivity and environmental sustainability. However, the application and effectiveness of sustainable agriculture and technologies like nanotechnology are not uniform across all regions.…”

“…Las principales aplicaciones de estas nanopartículas aprovechan sus características bactericidas y han sido utilizados para el diseño de productos antimicrobianos [23]. Los avances en nanotecnología han permitido desarrollar nanomateriales de diferentes elementos o compuestos, y el desarrollo de ciertas aplicaciones han demostrado que las nanopartículas pueden influir positivamente en el proceso de crecimiento de elementos vivos como algunas plantas [24], [25]. Una investigación in vitro demostró que las NP de óxido de zinc (ZnO NPs) obtenidas por síntesis verde mejoraron el crecimiento de raíces, brotes y en la producción de biomasa de la Juniperus procera.…”
