The purpose of the study was to determine the effectiveness of liquid NPK fertilizer with a composition of 12:9:7 on sweet corn plant. The research was conducted at the Mojosari Research Station, Mojokerto district, East Java, Indonesia, in September to December 2020, using a randomized complete block design with eight treatments and repeated four times. The treatments consisted of one treatment without fertilization (control), one treatment dose of 300 kg phonska + 300 kg urea per ha (recommendation), six treatments of liquid NPK fertilizer. Application of liquid NPK fertilizer is done by dissolving in water as much as 200 mL per plant. The results showed that the application of liquid NPK fertilizer had an effect on plant height, stem diameter, stover weight, cob length, ear diameter, and cob weight. The application of liquid NPK fertilizer at a dose of 12.5 cc L-1 gave the same or comparable response to the standard fertilization treatment with an agronomic effectiveness level > 95 %.
Key words: Agronomic effectiveness / maize / non granular fertilizer / yield
