Augmentation of Seedling Vigour using Biostimulants for Cowpea var VBN 4

As part of this research, an investigation was conducted to assess the impact of utilizing natural biostimulants on the biochemical and seedling characteristics of cowpea seeds variety VBN 4. Specifically, the study aimed to determine the most capable biostimulant in promoting enzyme activity and seedling vigor when applied at a 5% concentration for a period of eight hours. A total of eight different biostimulants were utilized in treating the seeds, and their outcomes were compared to those of untreated control seeds. The results revealed that humic acid at a 5% concentration and an eight-hour treatment period had the highest values for both enzyme activity and seedling vigor. Following closely behind were Pseudomonas fluorescens and brown kelp extract, showcasing their promising qualities as biostimulants. Overall, this study highlights the significant benefits that biostimulants offer to farmers as a means to increase seed viability and vigor. Based on these findings, it can be concluded that incorporating natural biostimulants into agricultural practices is a valuable strategy for improving crop yield and overall plant health.
