Studies on Use of Medicinal Plant Extracts as Priming Treatments for Healthy Germination and Seedling Growth of Bhima Red and Bhima Super Varieties in Onion

The present investigation of studies on the use of medicinal plant extracts as priming treatments for healthy germination and seedling growth in onion was carried out at the seed testing Laboratory, University of Horticultural Sciences Bagalkot. The varieties used in this study were Bhima red and Bhima super. The priming treatment of seeds has been carried on the varieties Bhima red and Bhima super with 4 treatments and 4 replications and treating the seeds with the extracts of Aloe vera (Aloe barbadensis), Calotropis (Calotropis gigantea), Neem (Azadiracta indica), Tulsi (Ocimum sanctum) with two different concentration of 0.25 and 0.50 % and primed seeds were kept in the incubator for 15 days and the seed germination, growth of shoot and root were measured. Variation in the growth has been significantly compared. The highest germination was recorded from Tulsi plant extract followed by the Aloe vera, Neem and Calotropis. The length of the root and shoot was recorded highest in the Tulsi followed by Aloe vera, Neem and calotropis.
