摘要:Shallot (Allium ascalonicum L.) is a prioritized vegetable crop which cultivated intensively in Indonesia. During 2016, there was La Nina phenomena happened around Indonesia and gave little indirect influences in the growth of shallots. La Nina had increased the monthly and annual rainfalls, thus phospate was not available in soil and Phosphate Solubilizing Bacteria (PSB) application was used to increase phospate availability. The purpose of this research was to determine PSB application to lowland shallot varieties with which cultivated in highland. The research was in Pancot, Tawangmangu, 1100 m above sea level in June 2016-January 2017 using Completely Randomized Block Design (CRBD) with two factors: lowland shallot varieties (Bima, Manjung, Mentes, Ilokos, and Rubaru) and highland shallot variety Tawangmangu; and PSB (no PSB and with PSB 10x6 cell g-1 soil). Observation variables included were plant height, number of leaves, the number of bulbs per plot, and dry weight of bulbs per plot. Data was analyzed by ANOVA continued by DMRT. Research showed that application of PSB had no effect on all observed variables and showed that Bima and Rubaru are the varieties which adaptive to the weather anomaly and could produced the optimal bulbs yield in highland.
