Shallot’s growth and production under sub-surface irrigation in vertical agriculture (verticulture) system

Abstract

One way to increase yields production of shallot plant can be done by planting in vertical agriculture (verticulture) system. The research aimed were to observe water consumption, to observe leaf length, to observe shallot weight, and to observe bulb quality of shallot. The research was done by experimental design that used sub-surface irrigation with emitter spacing P1 (15 cm), P2 (30 cm), and P3 (45 cm) that immersed in verticulture container with distance among holes 15 cm for each container. Shallot’s seed was planted in each hole that has 33 seeds in a verticulture container. The result shows that the least water consumption, the longest leaf length, the highest shallot weight, and the biggest bulb quality showed in verticulture container that contains irrigation tube with emitter spacing 15 cm. The conclusion that can be interpreted were sub-surface irrigation can be applied as irrigation system in vertical agriculture, where emitter spacing in irrigation tube as same as hole spacing in verticulture container.
