Abstract

The obstacles that farmers face by using the True Shallot Seed (TSS) due to the germination ability. In a laboratory level, the application of bio-stimulants was tested to enhance the TSS germination. Two types of bio-stimulants namely Bio A and Bio B with 16 treatment were tested with the TSS. Hypocotyl length, speed of seed germination, germination percentage, seedling growth rate, number of dead seeds and abnormal seeds, number of fungi-infected and bacteria-infected seeds were all measured. The results showed that soaking in Bio A for 1-3 hours reduced 38% - 46% of seeds attacked by seed-borne bacteria compared to controls. The Bio B treatment had a better effect on the speed of seed germination and germination percentage parameters, compared to Bio A.
