“…As concluded, TSS in the tropical lowlands could not develop flowers and produce seeds naturally. TSS could develop flowering and seed formation if planted in tropical highlands with an altitude of >1000 m ASL and an average daily temperature of 16–18°C (Askari‐Khorasgani & Pessarakli, 2019), but sometimes with poor viability seeds quality. However, combining several treatments such as vernalisation, benzyl amino purine (BAP), boron and pollinating insects could improve flowering and seed viability in tropical highlands to produce TSS on commercial scale (Rosliani et al, 2016).…”

“…Shallot bulbs form aggregates/clusters consisting of 5–10 bulbs on the true stem/discus. Therefore, shallot is propagated commonly using bulbs (Askari‐Khorasgani & Pessarakli, 2019; Major et al, 2018). However, there are constraints in the management of seed bulbs due to its heavy demand (0.9–1.5 tons/ha −1 ), high cost (40–45% production costs), bulb dormancy, specific storage requirements, distribution management and complicated seed certification system (Pangestuti & Sulistyaningsih, 2011; Rabinowitch, 2021; Rosliani et al, 2016; Shimeles, 2014).…”

Shallot (Allium cepa L. Aggregatum group) is an important Allium plant commonly grown in tropical countries, including Indonesia, and it is used as spice for daily cooking, medicine, cosmetics and dietary supplements. Since shallot is predominantly propagated vegetatively by bulbs, it augments pathogen accumulation which influences low seed bulb management as well as productivity. Hence, utilisation of seeds/True Seed Shallot (TSS) emerges an alternative propagation material. However, no information is available on the growth stages of shallot plants from TSS. The phenological growth stages of tropical shallot planted in lowland areas using seeds in accordance with the Biologische Bundesanstalt, Bundessortenamt nd CHemische Industrie (BBCH) scale are first described here. Five introduced TSS cultivars, that is, Tuk Tuk, Lokananta, Sanren, Maserati, Tropix and four landraces TSS cultivars, that is, Bima, Biru Lancor, Pancasona and Trisula, were used as planting materials to develop an extended numerical BBCH scale for the identification of different phenological growth stages of shallot from seed. The study was conducted in lowland areas under tropical conditions of Indonesia. Based on BBCH scale, phenology of tropical shallot from seed in lowland area exhibited five of the 10 principal stages (0–9): germination (stage 0), leaf development (stage 1), formation of lateral shoot/tiller of pseudostem (stage 2), development of bulb (harvestable vegetative part) (stage 4), and senescence (stage 9). The codification of the different growth stages is essential in determination of the correct timing for better crop management, particularly for transplanting, fertilisation, control of weeds, disease and pest, plant growth regulators application and harvest time. As an implication, these BBCH scales could be used in plant breeding activities to shorten the TSS life cycle.

“…Seeds and cultivation methods related to the varieties selection, fertilizing schedule and dose, seed spacing, and growing environment (lowlands) greatly determine the plant growth and productivity. In accordance with Ashkari-Khorasgani [22], cultivation methods are related to fertilization, seed spacing, mulch installation, and irrigation that greatly set the productivity of shallots.…”

The success of the shallots’ growth and production is strongly affected by the cultivation method, the variety selection, and the growing environment (location-specific cultivation). This study aims to evaluate the shallot’s growth using true shallot seed to cultivation methods in a lowland growing environment. The research is conducted in Pasar 1 Tanjung Sari-Medan community land located at an altitude of 32 meters, during June to September 2021. This study applies a factorial randomized block design, the first factor is the shallots variety using TSS (Lokananta and Sanren F1). The second factor is the difference in plant cultivation methods (seed supplier recommendation, modification of seed supplier recommendation, multiple production recommendation, modification of multiple productions). The results show that in the lowlands, plant height, number of leaves, and total of leaf area of Lokananta are higher than Sanren F1. The use of cultivation methods seed supplier recommendation increased in plant height and total leaf area. The combination of Lokananta treatment and seed supplier recommendation method results in the best plant growth indicated by an increase in plant height and total leaf area.

“…The problem in tuber research is that it is vulnerable to the environment, such as soil, temperature and rainfall [10]. Climate and soil conditions such as rainfall, humidity, soil air and temperature can affect plant growth and the risk of shallot farming [11]. Shallot production can be done by increasing the application of effective fertilization technology.…”

The main problem with shallots in Indonesia is planting material. The use of consumption tubers as planting material is very high. Efforts are needed to replace consumption tuber planting material with other planting materials such as aerial tubers. This study examines the potential yield of aerial tuber planting material and consumption tuber with fertilization treatment. The study used a Completely Randomized Block Design with a split-plot pattern with two factors, namely: fertilizer (as the main plot) with two levels, namely: with liquid and chemical fertilizer. Types of planting material (as a subplot) with three levels, namely aerial tubers, large consumption tubers (1.93-2.05 cm) and small consumption tubers (1.04-1.29 cm). Repeat three times. Liquid organic fertilizer can be used to improve the chemical quality of the soil. The combination of bulbils planting material with chemical fertilizer resulted in the highest fresh weight of bulbs per plot and dry weight of bulbs per plot, namely 394.67 grams and 338.67 grams, respectively. However, the highest number of bulbs planted in the treatment of large consumption bulbs was 7 bulbs. The diameter of bulbs produced from bulbils planting material and bulb consumption was the same. Shallot bulbs have potential as planting material.
