| Abstract | ||||
| AGRICULTURE is fundamental to ensuring global food security, with enhanced crop production being crucial. Phosphatic fertilizers serve an important role in sustaining agricultural productivity and meeting the needs of an expanding population. A field experiment was conducted to assess the effects of phosphorus fertilizer [ordinary superphosphate (OSP) and rock phosphate (RP)] with different particle sizes (without sieving, 1.0-0.5, 0.5-0.25, 0.25-0.125 and <0.063 mm) using loamy sand soil on the straw and grains yield of wheat, the content of NPK in the grains and the availability of phosphorus in the soil. The results indicated that the maximum straw and grain yields were reached for OSP (10.9 and 8.59 Mg ha-1, respectively) and RP (8.39 and 6.64 Mg ha-1, respectively) in soil treated with 1.0-0.5 mm particle size for both P fertilizers. The highest residual soil P (18.5 mg kg-1 for OSP and 23.9 mg kg-1 for RP) were observed in treatments with <0.063 mm particles. A highly negative correlation (r = -0.97 for OSP; r = -0.92 for RP) was observed between residual soil P and particle sizes of fertilizer. The results revealed that the maximum uptake of NPK was recorded in treatments 1.0-0.5 and 0.5-0.25 mm compared to whole fertilizers. The addition of RP significantly increased soil P (19.8 mg kg-1 soil) compared to OSP treatments (15.6 mg kg⁻¹ soil). It could be concluded that the segregation of P fertilizer is essential for enhancing soil P and maximizing wheat yield, providing valuable insights for agricultural practices in similar soil conditions. | ||||
