Abstract:
The major Sources of bio stimulants are Humic acid, chitosan, algae, beneficial bacteria and seaweed extract and found that the application of this bio stimulants improved the metabolic processes such as photosynthetic activities, respiration, ion absorption, leaf pigmentation, plant vigor and delayed fruit maturity. Seaweed (macro algae) are the marine plants (most under used bio resources) which belongs to the plant kingdom Thallophyta. Seaweed extracts are environmentally friendly, biodegradable, and non-toxic. It was anticipated that using seaweeds as a bio fertilizer would make up for soils that had lost or had insufficient nitrogen, phosphate, and potassium (N,P,K). Seaweed extracts like Ascophyllum nodosum, kelp, Kappaphycus and Gracilaria are good for rice growth and yield.
