The performance of true seed of shallot (TSS) growth and production in East Java

Abstract

True Seed Shallot (TSS) of shallot is shallot seed origin as solution of seed availability problem. Generally, farmers still use bulb seed for shallot production. This is because the aspect of shallot cultivation using TSS seed is still to be reviewed. The research objective was to known performance of growth and production of TSS in East Java. The Research was carried out in 2017 until 2018 at Probolinggo District and Batu city, using 2 (two) varieties, namely Trisula and Biru Lancor. The results showed that the growth phase of the Biru Lancor variety showed a better value than Trisula in each location with plant height (64.4 cm), number of leaves (78.2), number of tillers (14.5) and number of flowers (4,8). The generative phase showed that Trisula variety produced higher TSS yields but lower yields for bulb seed, whereas for Biru Lancor varieties the TSS yield was lower than bulb seed yields. Biru Lancor variety is also more resistant to environmental conditions but more susceptible to pest attack and the Trisula variety shows the opposite.
