A field experiment was planned and executed in randomized block design at Umiam during kharif 2019 to determine the grain yield and economics of upland directseeded rice (Oryza sativa L.) in North-Eastern Hill region under varying phosphorus management practices. The soil of the experimental plot was sandy-clay loam in texture with pH 4.2, high in organic carbon (1.62%) and available K (354 kg/ha), medium in available N (256 kg/ha) and low in available P (6.3 kg/ha). The plot managed with organic nutrient sources i.e. 25% FYM + 25% vermicompost + 25% poultry manure + PSB produced significantly higher number of yield attributes subsequently resulting in higher grain yields. This was followed by 100% RDP fertilized plot and 75% RDP+ PSB + AMF. In terms of economics, 100% RDP plot proved to be the most cost-effective owing to the less cost of fertilizers as compared to organic nutrient sources.
