Online published on 2 January, 2017. Abstract A field experiment was conducted during rabi 2014–15 at Agronomy Instructional Farm, C.P. College of Agriculture, Sardarkrushinagar on sandy loam soil to study the effect of integrated phosphorus management on growth & yield attributes and productivity of fenugreek. The experiment consisted of 10 combinations of integrated phosphorus management practices for application of recommended dose of phosphorus (RDP) to fenugreek i.e. 40 kg/ha through different sources viz., control, organic [vermicompost (VC) and castorcake (CC)] and inorganic fertilizer alone or in combination with or without microbial (PSB) inoculation. Results revealed that integration of 50% RDP through vermicompost + 50% RDP through inorganic fertilizer along with seed inoculation of PSB recorded higher growth attributes, viz., Plant height, branches/plant, dry matter accumulation/plant, nodules/plant and weight of nodules/plant; yield attributes viz., pod length, pods/plant and number of seeds/pod, seed yield and straw yield. It drastically increased the population of rhizobium and PSB in the soil after harvest of the crop as compared to other treatments. Maximum net return (Rs. 78, 195/ha) and benefit cost ratio (3.12) were also fetched with integrated application of 50% RDP through VC + 50% RDP through inorganic fertilizer + PSB.
