Abstract
Various types of biofertilizers can reduce the usage of chemical fertilizers, environmental
contamination and farm management costs. Seaweed extract-based biostimulants are
regarded as one of the best modern ecological plant growth enhancers. They have
been demonstrated to maximize agricultural output by successfully eliminating plant
diseases and abiotic stressors. Additionally, they have become known as environmentally
benign biofertilizers that enhance plants' resistance to inanimate objects and support
their development and general well-being. The purpose of this study is to create
Selenium Nanoparticles (Se NPs) using the natural aqueous extract of the brown seaweed
Lobophora variegata. Various analytical techniques have been used to study the properties
of the synthesized Se NPs. The antimicrobial activity against particular harmful
bacteria and fungi was analyzed. The green developed Selenium Nano Liquid Biofertilizer's
(SNLB) larvicidal activity was examined.
The study's main objective was to determine whether it would be feasible to create
Selenium Nano Liquid Biofertilizer (SNLB) using Selenium Nanoparticles (Se NPs)
made from marine brown algae Lobophora variegata. The study also aimed to evaluate
the effects of this SNLB on plant growth parameters and pigment levels, which are
found to triple in plants treated with SNLB.
