Seed storage conditions and the availability of shallot seeds are critical factors in the development of shallots. The main objective of this study was to determine the ideal storage conditions for several varieties of shallot (Allium cepa var aggregatum L.) on the physical quality of seeds, growth and yield of shallots. This research was conducted at the Experimental Garden, Indonesian Vegetables Research Institute, West Java. This research was conducted using a split-plot design with two replications. The main plot was a storage room which consists of three storage conditions, namely the growth chamber (temperature 1-2°C), shallot storage room (temperature 29-30°C), and room temperature (22.5°C). The subplot consists of seven shallot varieties, namely Bima Brebes, Mentes, Trisula, Pancasona, Pikatan, Kuning and Katumi. Firstly, the seed is stored in the storage area and afterwards is planted in the field. Observation parameters included seed quality after storage, growth components and yield components. The results showed the interaction effect of seed storage conditions and cultivars on the number of seeds that grew (%) on day 5 DAP and the dry weight of bulbs per hectare (tons). Kuning cultivar stored in the growth chamber (1-2°C) produced the highest dry weight (9.08 tons) compared to all combinations of storage space and varieties unless stored in shallot storage (29-30°C).

Garlic is an important commodity because it is needed as a cooking spice and industrial ingredient, garlic is an ancient functional food and herbal medicine. Almost 90% of the national requirement is imported. An effort to increase its production has been made in recent years. Temanggung Regency has local varieties of garlic, namely Geol, that need to be tested for growth ability, production, and quality. The planting season in this area is mostly in the rainy season, starting from November-December every year, resulting in lower productivity. For that reason, an experiment was conducted started in July 2021 where the farmers mostly planted tobacco. This study aimed to evaluate the growth and production of Geol compared to the commonly planted varieties in Temanggung. The research was conducted for five months in Petarangan village, Kledung sub-district, Temanggung district, Central Java. The design used was a randomized block design with four varieties and four replications. The varieties observed were Lumbu Hijau, Lumbu Kuning, Tawangmangu Baru, and the local variety Geol. The plant growth, production, and product quality were observed. The result showed that the local variety Geol had a higher dry yield per hectare (7.39 tons) than Tawangmangu Baru (6.17 tons) and Lumbu Kuning (6.67 tons). Generally, it showed that Geol had the same production capability as other varieties, but it has larger cloves size, is faster harvested, and is preferred by consumers (farmers, traders, and housewives).
