Abstract
Shallot seed production using TSS (True Shallot Seed) is more effective and efficient in terms of storage and distribution,but it must be sown first. The purpose of this study was to determine response and obtain the best combination of number and age of TSS seedlings in increasing shallot seeds production. The experiment was arranged in a randomized complete design of number x age of seedling with 3 replications. The number of seedling,consisted of. 1, 2, 3, and 4 seedling for each planting hole and the age of seedling,consisted of. 25, 35, 45, and 55 DAS (Days After Seedling). The result showed the number and age of TSS seedlings affected vegetative growth parameters (plant height and number of leaves), yield (yield per m2, dry yield per m2, sample yield, sample dry yield), productivity, and characteristics of the seed bulbs produced (number, diameter, and weight). The treatment of 3 seedlings per planting hole and 35 DAS (Days After Seedling) significantly and consistently showed better response than other treatments. That treatment able to increased vegetative growth parameters (plant height and number of leaves), yield (yield per m2, dry yield per m2, sample yield, sample dry yield), productivity and number of bulbs with lighter weight and smaller diameter characteristics of bulbs.
