Abstract

Background: Seaweed extracts are rich in various active compounds, including polysaccharides, polyphenols, and phytohormones which helps in nutrient uptake and enhance the growth of crops, both in challenging and normal favourable conditions. In this study, seaweed extracts of Kappaphycus alvarezii and Sargassam wightii have been explored for their ability to improve seed germination of Bhendi. Method: Bhendi seeds were primed with two seaweed extracts viz., Kappaphycus alvarezii and Sargassam wightii at three soaking durations viz., 8, 16, and 24 hours with five different concentrations viz., 0.5, 1.0, 1.5, 2.0 and 2.5%. The experiment was designed as factorial completely randomized design with 4 replications. Observations were recorded on various germination related traits. The mean data were collected and analysed for individual factor effect and their interactions. Results: The present study revealed that the bhendi seeds primed with Sargassam wightii at 2.5% for 24 hours has the highest germination ability and showed superior performance than other treatments for all the seed germination traits viz., first count (36%), days to 50% emergence (4.97 days), days to maximum emergence (9.31 days), speed of germination (4.42), co-efficient of variation of germination time (33.38), germination index (4.58 days), mean daily germination (8.56), peak value of germination (10.29) and germination value (88.06). Conclusion: Among all the treatments, bhendi seeds soaked in Sargassam wightii at 2.5% for 24 hours had positively and significantly influenced all the seed germination traits when compared to all the other treatments.
