Medicinal plant of Aloe vera L. are used in food, healthy, cosmetic and medical industry. Pot sowing is one of the production methods of this plant. In this conditions evaluation of different urea level on yield and yield component in pot sowing essential. For this purpose, an experiment was conducted as a completely randomized design in five levels of nitrogen fertilizer as urea (0, 50, 100, 150 and 200 kg.ha-1) with three replications (10 pots for each replication) in the greenhouse in 2010. In this experiment, traits such as leaf length, of width, thickness, number and shoot number, total biomass, weight and percentage gels were studied. Analysis of variance based on the effect of nitrogen on total biomass, weight of gel, leaf width and number was significant at the one percent level and characteristics of the gel percentage and leaf length at the level of five percent was significant. But effect of nitrogen on leaf thickness and number of shoot traits, was not significant. The highest biomass production was obtained at 50 kg.ha-1 N with 1039 g per pot. The highest gel weight (839 g) was obtained at 50 kg N. Gel percentage production was 72.7% at this level of nitrogen application and did not have significant difference with 100 kg N treatment.
