Abstract: A field experiment was conducted during rabi season of 2014-15 on sandy loam soil to “Effect of organic, inorganic fertilizers and plant densities on performance of radish (Raphanus sativas L.)”. The experiment consisted three treatment of organic manures (control, VC @ 5 t/ha and FYM @ 15 t/ha), three treatment of inorganic manures (control, 50% RDF of NPK and 100% RDF of NPK) and two treatment of plant densities (20 x 10 cm and 30 x 10 cm), thereby making eighteen treatment combinations tested in randomized block design with three replications. Results indicated that application of vermicompost @ 5 t/ha and 100% RDF of NPK significantly higher yield and yield attributes of radish over control, FYM @ 15 t/ha and control, 50% RDF of NPK, respectively. However, the application of FYM @ 15 t/ha significantly increased the root to shoot ratio and remained at par with vermicompost @ 5 t/ha over control. But, the application of 50% RDF of NPK significantly increased the root to shoot ratio and remained at par with 100% RDF of NPK over control. The result also indicated the plant spacing 30×10 cm significantly higher yield attributes and economic of radish over plant spacing 20×10 cm. However, the plant spacing 20×10 cm significantly increased the root to shoot ratio and remained at par with plant spacing 30×10 cm.The economics of maximum net returns (262595 /ha) was recorded with combined application of vermicompost 5 t/ha + 100 % RDF of NPK + 30 x 10 cm spacing and maximum B: C ratio (3.28) was recorded with combined application of vermicompost 5 t/ha + 50 % RDF of NPK + 30 x 10 cm spacing. Radish was significantly superior to other treatments in including sole or combination in different proportions.
