Effect of Chitosan Coated Immobilized Algal Cells as Plant Growth Promoter in Vigna radiata L.

Abstract

The present study is design to investigate effect of immobilized algal cells as a growth promoter for improving quality and quantity of Leguminosae plant such as mung bean (Vigna radiata). The experiment was conducted in plant growth chamber during month of January 2024. The experiment was performed in plastic glass using cocopeat. Immobilized beads were coated with Chitosan and followed by sun drying of that bead. The experiment consists of five treatments which was T0: Control, T1: With chitosan Chlorococcum beads, T2: Without chitosan Chlorococcum beads, T3: With chitosan Scenedesmus beads and T4: Without chitosan Scenedesmus beads. The result revealed that seeds treated with Chitosan treatment of algal beads (T1 and T3) it gives significant growth as compared to Control (T0). Shoot length and root length were significantly increased in treatments (T1 and T3) as compared to control. Carbon, Nitrogen and Phosphorous concentration were significantly increased in all treatment as compared to control whereas, Sulphur concentration was increased in control. Chlorophyll content was also, significantly increased in all treatment compared to control.
