ISOLASI CENDAWAN PENYIMPANAN PADA BAWANG MERAH DAN STUDI PERTUMBUHAN SERTA PRODUKSI BAWANG MERAH DARI SUMBER BENIH UMBI DENGAN BEBERAPA METODE SIMPAN

Abstract

As an agricultural commodity and a staple household necessity, shallots play an important role in the economy. Efforts to increase shallot production are often hindered by pathogens that cause disease. Isolation and identification of fungi that appear during the storage process using various storage methods are carried out to provide more specific microbiological information regarding potential causes of seed damage. This study aims to identify the types of fungi that infect shallots from several storage methods and to determine the effect of storage methods on the growth and tuber production of shallot seeds in the field. This study uses a Randomized Block Design (RBD) with three storage methods (P), namely Drying House at 34°C (P1), Room Temperature at 26-27°C (P2), and Air Conditioned Room at 16°C (P3), along with three seed tuber sizes: Large (B), Medium (S), and Small (K). The isolation results showed that there are three types of fungi growing on storage bulbs, namely Fusarium sp., Aspergillus niger, and Penicillium sp. Statistical analysis results indicated that the combination of storage methods and bulb size had a very significant effect on the number of shoots and a significant effect on the number of leaves, but had no significant effect on plant height, bulb diameter, fresh weight, and dry weight. Storing shallot bulbs in drying houses and at room temperature resulted in better growth and production compared to storage in air-conditioned rooms, and it was more effective in suppressing the growth of pathogenic fungi that cause bulb damage.The results of this study are important in seed storage management.
