“…Some capsules may be empty. Empty capsules are caused by the limited pollen attached to the surface of the stigma, so the number of seeds that develop in one capsule is also very limited [12]. The number of capsules and seeds per umbel tends to depend on the activity of pollinating insects [26].…”

“…The percentage of capsule formation is greater with the help of pollinating insects (cross-pollination) compared to other methods because shallots are dichogamous and partly self-incompatible [11]. Among the pollinating insects that are most effective in shallots are Apis cerana and Apis mellifera [12]. However, their unexpected results couldn't be the same as what humans could do on purpose.…”

Producing seeds from shallot flower requires proper pollination techniques to form pithy seeds. This study aims to determine the effectiveness of several pollination methods in producing true shallot seeds (TSS). The research was conducted in Cilame Village, Ngamprah District, West Bandung Regency, West Java at an altitude of 900 m asl. The study used a completely randomized design (CRD) which consisted of four treatments and six replications. The treatments are pollination methods: control (natural pollination), using a brush, using stroking/bare hand method, and a combination of using a brush and stroking. Pollination treatment was carried out when the flowers have bloomed for three consecutive days. The variables observed were plant height, number of tillers, number of flowers per clump, umbel diameter, number of capsules per umbel, and seed production per umbel. Data were analyzed using ANOVA, and if the results of the F test were significantly different, it was continued with DMRT (Duncan’s Multiple Range Test) and correlation. The result showed that pollination by stroking is the most effective to increasing TSS production per umbel. Seed production per umbel by stroking was 0.89g and control (natural pollination) was 0.23g. Stroking method increased TSS production per umbel by 74.16 % compared to control. Therefore, the method could become an alternative to increase the formation of TSS in overcoming the limitations of natural pollinator.

Management of True Seed of Shallot (TSS) production is an important part of supporting Indonesia shallot seed availability. It should involve various parties such as governments, privates, and shallot farmers to guarantee TSS quality and quantity of TSS. The study aims to identify governments' and farmers' preferences toward TSS institutional model in Indonesia. The study was undertaken in East Java from March to August 2016. Twenty-eight respondents from around East Java were purposively selected. Four options of the institution model of shallot seed were offered. The data was analyzed using the Analytical Hierarchy Process. The result showed that the preferred institution model for TSS by the respondents was the first option. In the model, Indonesian Vegetables Research Institute provided the high quality of shallot bulb seed and produced TSS for Breeder Seed. Meanwhile, other Indonesian government seed bodies/private generated bulb seed for Breeder Seed. Then, the University/Assessment Institute of Agricultural Technology/private produced TSS and bulb seed for Foundation Seed.Furthermore, selected shallot breeders produced TSS and bulb seed for Stock Seed and Extension Seed. The model could solve shallot seed quality and quantity problems' as it engaged the competent institutions. Therefore, the model could be recommended for TSS production nationally.

“…In recent years, the study of true shallot seed production in Indonesia has received more attention. They include selection of area production, nutrient management and plant density (Rosliani et al 2016a;Rosliani et al 2016b;Hilman et al 2016;Palupi et al 2016). The successful and efficient technology of planting true shallot seed at different locations and cultivars remain, however, a major challenge.…”

<p>True shallot seed (<em>Allium cepa var Aggregatum group</em>) is an alternative way of growing shallot. Different environments and cultivars need a specific study. The aim of this research was to find out the best technology to grow Trisula true shallot seed by managing plant densities and applying compost and biofertilizer in alluvial soils. The study was performed from May to October 2015, using a split-plot design with four replications. The main plot was plant density: 100 plants m-2 and 70 plants m-2. Subplots were five fertilizer application combinations, they were 100% recommended dose of NPK (R-NPK), 100% R-NPK + compost, 100% R-NPK + compost + biofertilizer, 50% R-NPK + compost and 50% R-NPK + compost + biofertilizer. Results showed that biomass and bulb yield were significantly affected by plant density and fertilizer application. The reduced 50% R-NPK by substituting with compost and biofertilizer was unable to maintain shallot bulb yield equal to 100% R-NPK, suggesting insufficient nutrients derived from compost to satisfy the shallot requirement. The best technology to grow true shallot seed of Trisula variety was 100 plants m-2 plant density and 100% NPK (consisting of 180 kg N ha-1, 52 kg P ha-1 and 50 kg K ha-1) with 2.5 t ha-1 compost that achieved the highest bulb yield of 9.83 t ha-1 and increased the revenue.</p>
