| dc.description.abstract | Shallot (Allium ascalonicum L.) is one of the horticultural plant that is often
used as seasonings and medicines. Indonesian citizens consuming shallots as their
daily necessity that increasing the market demand for shallot while the production
still has not maximized yet, therefore the farmer is expected to take efforts to
increase the production. The use of unbalanced organic and inorganic fertilizers
and the decrease of soil fertility levels are some factors that caused the less
production of shallots. By combining organic and inorganic fertilizers can be an
effort to increase shallot production while keep maintaining the soil quality. This
research was conducted at cassa house, Medan Johor District, North Sumatra, at
an altitude 35 meters above sea level (masl) with coordinates 3°31'17.3'‘ E and
98°39'43.4’' S, via GPS (Global Positioning System) from April to June 2025. This
experiment used Randomized Complete Block Design (RCBD) consisting of 2
treatmens with 3 replications. The first factor is the doses of NPK fertilizer: 0, 200,
400 kg/ha. The second factor is the concentration of liquid organic fertilizer: 0, 50,
100, 150 ml/L. The results of the research showed that the dose of NPK fertilizer
400 kg/ha had significantly produced the highest plant length, number of leaves,
diameter of the bulb, number of bulb, fresh weight of the bulb and dry weight of the
bulb. While the concentration of liquid organic fertilizer and the interaction from
both factors had no significant effect on all parameters. | en_US |
