Rahman Rahman, Oktavianus Lumban Tobing, Setyono Setyono

Abstract

This study was conducted at the experiment garden of Agrotechnology Department, Djuanda
University, Bogor, from July to September 2018. The study was aimed at assessing the effects of
the application of nitrogen fertilizer and mung bean sprout extract on the growth and production
of edamame (Glycine max L. Merril) plants. The experimental design used was a factorial
completely randomized design. The first factor is the dose of N fertilizer with four levels, namely
without N (0 kg N / ha), a half recommendation of N fertilizer (34.5 kg N / ha), one recommendation
of N fertilizer (69 kg N / ha), and one and a half recommendation of N fertilizer (103.5 kg N / ha).
The second factor is the concentration of mung bean sprout extract with four levels, namely without
mung bean sprout extract (0g tauge extract / l water), a half recommendation of mung bean sprout
extract (75g tauge extract/ l water), one recommendation of mung bean sprout extract (150g tauge
extract / l water) and one and a half recommendation of mung bean sprout extract (225g tauge
extract/ l water). The results showed that the dose of N fertilizer significantly affected the widest
leaf area. The concentration of mung bean sprout extract significantly affected the number of shoots
at 6 and 7 weeks after planting (MST).
Keywords: edamame soybean, N fertilizer, mung bean sprout
