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.

The Evaluation of Production, Chlorophyll Content and Number of Flower of Samosir Local Shallots through Application of Gibberellin and Boron in the Highlands

“…When the cultivation was carried out, high rainfall was prevalent from August to October 2022, which could reduce the production and flowering potential of shallot plants [6], [21]. Shallot plants have high production and flowering potential during the dry season [7], [35].…”

“…Samosir local shallots cultivated in the Lake Toba area are grown at 925 ± 1131 m altitude. Altitude and local shallot production in Samosir are negatively correlated, meaning the higher the altitude, the less the production will decrease [6], [7]. Therefore, it is necessary to experiment to increase production with appropriate technical cultivation treatment for the highlands.…”

Effect of Gibberellic Acid (GA3) Concentration and Seedling Media Composition on the Germination and Growth of Shallots (Allium ascalonicum L.) from True Shallot Seed

“…True Shallot Seeds which are sown as seedlings can be an alternative for providing planting material that is more efficient and profitable [6]. However, currently using TSS seeds is still considered more difficult and takes longer than cultivating using tuber seeds with a seeding time of 42 days after sowing [7]. Seeds that are susceptible to deterioration during the storage period also affect the low percentage of growth in the field which results in decreased viability [8].…”
