Growth and Production of Samosir Local Shallots (Allium ascalonicum L.) with Various Sulfur Doses

Abstract

The production of Samosir Local Shallots has been decreasing due to land area reduction and the application of cultivation technologies such as fertilization which have not been applied intensively. Sulfur application is expected to be able to increase the growth and production of Samosir local shallots. This research aim was to determine the growth and production of Samosir Local Shallot (Allium ascalonicum L.) on various doses of sulfur. This research used a non-factorial completely randomized design, namely sulfur dose (S) with four levels of; S0 = No Sulfur, S1 = 6 g / plot, S2 = 12 g / plot, S3 = 18 g / plot, number of replications = 6 replications, number plot = 24 plots. The results showed that the application of sulfur to the growth and production of shallots was higher than without sulfur, application of sulfur at a dose of 0, 6.12, and 18 g / plot was not significantly different from the parameters of plant height, number of leaves, number of tubers, and significantly different from the parameters of tuber fresh weight, and tuber dry weight. The level of sulfur (S) in the shallot at the end of the research ranged from 0.129 to 0.158 mg/kg.
