Biogenic synthesis and characterization of Metal Sulphide nanocomposites and its application to seed germination

Abstract

A new agricultural revolution is needed to enhance crop yield and ensure the quality and safety of food in a sustainable manner. Agricultural sustainability can be improved with the use of nanotechnology. In addition to impacting germination and seedling establishment, effective seed nano-priming can alter seed metabolism and signalling pathways, and also affecting the entire plant life span. The present study provides an overview of benefits of Cobalt Sulphide Nanocomposites and the germination of Trigonella foenum-graecum and Brassica nigra seeds as a contribution to efficient agricultural practices. The synthesised Metalsulphide nanocomposites were characterized by UV-visible DRS, SEM and X-ray powder diffraction (XRD) methods. In Petri dishes, Cobalt Sulphide Nanocomposites were evaluated for the germination of Trigonella foenum-graecum and, Brassica nigra seeds. Several germination parameters have been investigated in relation to the concentration of Cobalt Sulphide Nanocomposites. The results shown an improvement in germination, shoot and root length, and germination time compared to the control treatment. It was discovered that a modest amount of time spent for soaking of the seeds helped them to germinate well.
