A field experiment was conducted on loamy sand of Agricultural Research Station, S. D. Agricultural University, Aseda during the years 2021-22 and 2022-23 to study “Phosphorus management in potato (Solanum tuberosum L.) - pearlmillet (Pennisetum glaucum L.) cropping sequence under North Gujarat condition”. Five phosphorus management treatments applied to potato during rabi season were laid out in randomized block design and fifteen treatment combinations comprising residual effect of preceding five phosphorus management treatments of potato followed by three levels of RDP to pearlmillet tested in spilt plot design with four replications. The soil of the experimental plot was very low in organic carbon and available nitrogen, medium in available phosphorus and high in available potash. Result showed that electrical conductivity, pH, available phosphorus and potash of soil after harvest of potato crop was found non significantly affected due to phosphorus management but on pooled basis treatment A5: 75% RDP + VAM + Enriched FYM @10 t/ha recorded significantly higher organic carbon content (0.350%) and available nitrogen content (117.1 kg N/ha) after harvest of potato crop. In case of pearlmillet, the result on electrical conductivity, treatment A1: 100% RDP recorded significantly highest electrical conductivity of 0.359 dS/m and pH (7.43) but higher amount of organic carbon (0.285%) was recorded by the treatment A5: 75% RDP + VAM + Enriched FYM @10t/ha after harvest of pearlmillet crop.
