Sholihah, Sofi Marwatus (2025) THE COMBINATION EFFECTS OF SILICA-MODIFIED LIQUID ORGANIC FERTILIZER AND VARIETIES ON SHALLOT PRODUCTIVITY (Allium ascalonicum L.). S1 Undergraduate thesis, Universitas Darussalam Gontor.
Abstract
The onion plant (Allium ascalonicum L.) is a vegetable spice used as a flavor enhancer in cooking. In Indonesia, shallot cultivation holds good prospects due to the increasing demand for shallots, but its productivity remains relatively low. One alternative to increase shallot productivity is through fertilization and the use of appropriate varieties. Organic fertilization using liquid organic fertilizer (POC) is a solution to reduce the use of inorganic fertilizers, which have a negative impact on the environment. POC can be modified by adding silica. Silica is a nutrient compound (SiO₂) essential for plant growth, though its role as a nutrient has not received much attention. This study aims to determine the effect of silica-modified liquid organic fertilizer (POC) and varieties on shallot productivity. The research was conducted at the experimental field of Darussalam Gontor Putri Mantingan University from November 22, 2023, to January 21, 2024. The study used a split plot design with two factors. The first factor is silica-modified POC, consisting of three levels: P1 = POC 5 ml + Si 5 g.l-1, P2 = POC 10 ml + Si 5 g.l-1, and P3 = no fertilizer (control). The second factor is the variety, consisting of two levels: V1 = Bima Brebes and V2 = Thailand. The results of the study showed that the treatment of POC 5 ml + Si 5 g.l-1 had a significant effect on the number of leaves, number of tillers, and the wet and dry weight of both plants and tubers per sample. The Bima Brebes variety increased plant height, diameter, and the wet and dry weight of both leaves and tubers per sample. However, the combination of silica-modified POC and varieties did not show a significant effect. Keywords: Shallots, Liquid Organic Fertilizer, Silica, Varieties
