Each treatment were repeated 4 times so that there were 24 expermental units whith  4 samples per replication so that the total of plant number were 96 plants. The observation variables in this study were plant height, number of leaves, number of tillers, root volume, leaf dry weight, root dry weight, fresh leaf weight. Observations were also made on the environmental conditions of the study, such as rainfall, air temperature, humidity. The results showed that the administration of manure and N fertilizer with a dose of chicken manure 20 tons / ha and 100 kg / ha Urea was an effective dose on the average of each observation variable of leeks on peat soil. Keywords: spring onion, manure, N fertilizer and peat.]]>
