Organic Fertilization on Shallot

Abstract

The application of organic fertilizer aims to increase the quantity and quality of shallots and reduce the rate of weight loss of shallots in the storage process, as well as increase soil fertility, reduce chemical inputs, and be environmentally friendly and sustainable. Applying organic fertilizers to the soil plays an  important role in improving soil structure so that it increases air aeration and smooth water movement, as well as increasing the bulk density of the soil, thereby increasing the absorption of water in the soil and increasing plant growth and production. Using organic fertilizer on shallots can affect the number of tillers and plant tubers because applying organic fertilizer will form granules that bind without clay. As a result, the soil becomes more porous so that roots and tubers can easily penetrate and form larger and more numerous tubers. Organic fertilizers are a source of minerals and energy for microorganisms to break down, raise soil pH and increase cation exchange capacity, improving efficiency and nutrient uptake of N, P, and K and increasing crop yields.
