The Effect of Number and Age of TSS (True Shallot Seed) Seedling on Shallot Seed Production

Abstract

Shallot seed production using true shallot seed (TSS) 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 × age of seedling with 3 replications. The number of seedlings consisted of 1, 2, 3, and 4 seedlings for each planting hole, and the age of seedlings consisted of 25, 35, 45, and 55 days after seeding (DAS). The result showed the number and age of TSS seedlings affected vegetative growth parameters (plant height and the number of leaves), yield (yield per m 2 , dry yield per m 2 , 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 significantly and consistently showed better response than other treatments. That treatment increased vegetative growth parameters (plant height and the number of leaves), yield (yield per m 2 , dry yield per m 2 , sample yield, sample dry yield), productivity, and the number of bulbs with lighter weight and smaller diameter characteristics of bulbs.
