Abstract:
Laboratory experiment was conducted during 2023 to determine the effect of seaweed based seed coating on physiological and biochemical attributes of paddy and maize. Seeds were coated with different treatments viz., T1-control, T2- Water extract of sargassum, T3- Methanol extract of sargassum, T4- water extract of Kappaphycus, T5- Methanol extract of Kappaphycus, T6- Methanol extracts of Sargassum + Kappaphycus along with acacia gum. The physiological quality and biochemical parameters revealed that, methanol extract of sargassum seed coating registered higher germination, root length, shoot length, dry weight, vigour index, dehydrogenase activity and lower electrical conductivity.
