The influence of bio-stimulant Aquasap powder derived from the red seaweed Kappaphycus alvarezii was applied at 0.2% through foliar application on bellary onion at the establishment, vegetative, bulb formation and bulb development stage. Bulb yield and quality parameters such as total soluble solid, moisture content, ash content, organic content, pyruvic acid content, physiological loss and rotting percentage were studied. The crop yield in terms of bulb in treated plant was 31.65% over control with no statistical significant in the content of pyruvic between treated and control plants.


Keywords: Kappaphycus alvarezii, Onion, Bio-stimulant, Pyruvic acid, Organic nutrient, Aquasap powder.
