A field experiment was conducted to study the influence of nutrient management on productivity and competition functions of rainfedpigeonpea + radish intercropping system in north eastern ghat zone of Odisha. The study was carried out for two consecutive years during Kharif seasons of 2018 and 2019 at Instructional Farm, RRTTS, G.Udayagiri, OUAT, Kandhamal, Odisha with twelve treatments replicated thrice in a randomized block design. Among the intercropping systems with different levels of nutrient management practices, almost all the growth parameters as well as yield attributing parameters, yield and competition functionsviz.pigeonpea equivalent yield(PEY), monetary advantage (Rs.56336/ha),land equivalent ratio (LER), area time equivalent ratio(ATER),relative value total (RVT), relative crowding co-efficient(RCC) and aggressivity(A) showed the higher values with the treatment where 100 % RDF was applied to the base crop as well as to the intercrop. Sole crop of pigeonpea with 100% RDF produced the highest seed yield (1195 kg ha-1) andsole radish crop with 100% RDF showed the highest root yield (17.70 t ha-1) over other treatments followed by pigeonpea + radish with 100 % RDF to base crop + 100% RDF to intercrop during both the years of experiment and in pooled data.The highest pigeonpea equivalent yield (1984 kg/ha),monetary advantage (Rs.56336/ha),land equivalent ratio (1.81), area time equivalent ratio(44.53), relative value total (2.63),relative crowding co-efficient(107.36), andaggressivity (A = +1.19) ) were obtained where 100 % RDF was applied to the base crop as well as to the intercrop. Key words:pigeonpea(base crop), radish(intercrop), intercropping, nutrient management, yield,pigeonpea equivalent yield,competition functionsand recommended dose of fertilisers (RDF).
