Abstract

Shallot production in Indonesia is based on crops grown from seed bulbs. The introduction of True Seed Shallot (TSS) could be an option to improve competiveness of Indonesian shallot production. In the period 2007 till 2010 a research project was conducted to improve growing techniques of TSS. Seed emergence in the nursery was improved if the seed was sown in furrows 0.5-1.5 cm deep and by closing the furrow after sowing with soil instead of burned rice husks. Compared to traditional seed bulb crops productivity of TSS was much higher, up to twice as high in some experiments, while the growing period of TSS was two to three weeks longer. A recently developed cultivar, ‘Sanren’, which is an improvement in productivity, earliness, quality for the local market and which can be grown at a lower plant density than the older cultivar ‘Tuktuk’, has increased feasibility of TSS in Indonesia. Optimal plant density of ‘Tuktuk’ was 175 plants per m2; optimal plant density of ‘Sanren’ was about 75-100 plants per m2, depending on the costs of seedlings. Optimal nitrogen fertilization of ‘Tuktuk’ was 180 kg N/ha; optimal nitrogen fertilization of ‘Sanren’ was 240 kg N/ha. However, additional research is needed to investigate the effect of nitrogen on quality of the harvested bulbs.
