Abstract : A field experiment was conducted in red sandy loam soil with tomato (Lycopersicon exculentum Mill) var. CO 3 as test crop to evaluate the influence of organic N sources on soil physical properties and yield of tomato. The organic N sources tried were pig manure, fish meal, pressmud, poultry manure and FYM. Urea was taken for comparison. Application of organic N sources increased the saturated hydraulic conductivity, aggregate stability, total porosity and non-capillary porosity significantly than control. The N and P contents of the tomato crop were non significant. Application of 150 kg N ha-1 in the form of fish meal increased the dry matter production, N and P uptake. Application of poultry manure increased the K content and uptake; fruit and seed yield. Seed recovery was increased due to application of 150 kg N ha-1 through pig manure and 75 kg N ha-1 through pressmud.
