The field experiment was conducted at the central research farm Soil Science Research Farm of SHUATS Prayagraj, (U.P.) on, sandy loam soil to “Influence of Phosphorus and Zinc on Physio-chemical Properties of Soil on Cowpea (Vigna unguiculata L.)” during Kharif season of 2022. There are nine treatment combinations comprised in randomized block design with three replications making a total of 27 experimental plots. The soil samples were taken in two depths (0-15 cm & 15-30 cm) for analysis. The results showed that the application of Phosphorus and Zinc had a significant and non-significant effect on soil physico-chemical properties. The maximum bulk density (1.52 and 1.52 Mg-3), particle density (2.61 and 2.63 Mg m-3), and pH (7.20 and 7.25) were recorded in T1 (Absolute control) at 0-15 and 15-30 cm depth. Similarly, the maximum percentage EC (0.48 and 0.49 dS m-1), pore space (48.49 and 47.99%), water holding capacity (44.75 and 44.03%), percentage organic carbon (0.47 and 0.46%), available nitrogen (288.14 and 287.68 kg ha-1), phosphorus (29.60 and 28.85 kg ha-1) and potassium (192.41 and. 191.54 kg ha-1) was recorded in T9 (P2O5 @100% + Zn @ 100%)
