Abstract


The objective of research was to know the production of soybean with application of various
N sources and differences of groundwater conditions. Research conducted at the Screen House
Faculty of Agriculture, University of Sumatera Utara, Medan on February until May 2012, using a
randomized block design factorial with two factors and three replications. The first factor was
sources of nitrogen consisted of without N sources, inorganic N sources (Urea), biological N
sources (Bradyrhizobium japonicum), organik N sources (straw compost) (50 g/polybag), and
manure (50 g / polybag). The second factor was groundwater conditions consisted of 60%, 70% and
80% field capacity. The results showed that groundwater conditions were significantly difference to
dry weight seeds/plant and pods containing, Effect of N source and interaction between application
of various N sources
