Abstract
The present study aimed to determine how seed treatment with bio-stimulants can enhance seed germination, seedling growth, and biochemical parameters in cowpea var VBN 4. According to the findings, the use of bio-stimulants enhanced both seed germination rate and seedling development in cowpea when compared to a control treatment that did not receive bio-stimulants. Compared to other treatments, cowpea seeds that were exposed to humic acid at a 5% concentration and brown kelp extract for eight hours had a higher rate of germination. Significant improvements were observed in the seedling vigour indexes, shoot and root length, total dry matter production, and biochemical parameters (catalase and peroxidase activity) following an 8-hour treatment with 5% humic acid and Brown Kelp. The vigour of Cowpea seedlings can be increased by applying these treatments.
