Traditional Indonesian shallot production is based on seed bulbs but True Seed Shallots (TSS) could improve competitiveness of the industry. This study assesses numerous factors such as, seed raising mixtures, sowing depth and furrow fill, productivity comparison of TSS cultivars and seed bulb cultivars, plant density and nitrogen fertilisation, for their impact on shallot growth and production. Each experiment is reported on and discussed separately. The report discusses the impact of these different factors on a range of shallot characteristics such as emergence, growing period, yield, bulb size, bulb colour and storage quality. The results lead the authors to identify areas for additional research such as the impact of nitrogen fertiliser on storage quality of bulbs and the mechanism through which stable manure improves seedling emergence. The authors conclude that TSS could be a viable option for improving the competitiveness of Indonesia's shallot production. TSS yield's averaged 70 and 113% higher than the seed bulb cultivar 'Bima curut' but exhibited a 2-3 week longer growing period. The report discusses optimal nitrogen fertiliser rates and plant densities for the TSS and seed bulb cultivars.
