ABSTRACT

The shallots are one of the leading vegetable commodities, but have not shown a real increase in production every year so that efforts are needed to increase the production of shallots. This study aimed to obtain the optimum dose of KNO3 fertilizer and liquid organic fertilizer in increasing the growth and yield of shallots. The study was conducted at the Balai Benih Induk, Medan, North Sumatra, Indonesia from March-June 2017. This study used factorial randomized block design with three replications. The first factor is the dose of KNO3 fertilizer: 0 g/plot, 15 g/plot, 25 g/plot, 40 g/plot. The second factor is liquid organic fertilizer: 4.5 mL/L water, 9 mL/L water, 13.5 mL/L water. The results showed that the 40 g/plot KNO3 fertilizer gave the best growth and yield of shallots. Provision of liquid organic fertilizer 13.5 mL/L water and interaction treatment between 25 g/plot of KNO3 fertilizer and 40 g/plot with a concentration of liquid organic fertilizer 13.5 mL/L of water could only increasing the number of shallot leaves but have not been able to increase the yield of shallot bulbs.
