Abstract
- The aim of the study was to investigate the impact of phosphorus (P) dose application effects on bread wheat (Triticum aestivum) yield, mineral nutrients concentration and soil C (C) and nitrogen (N) concentration. From 1998to date, the same soil plots (200 m2) have been fertilized regularly with the same P fertilizer doses, namely 0 (PO), 50 (P50), 100 (P100), 200 (P200) kg P2O5 ha−1 as triple superphosphate (TSP). For the current study, fertilization was done 1 week before seed planting in 2013. Wheat yield increased with increasing P dose applications under long-term field conditions. Compared to the control treatment, 50, 100 and 200 P2O5 ha−1 application significantly increased wheat yield by 60%, 85% and 138%, respectively. Agronomic efficiency decreased with P-level increases. Indigenous root infection results and number of spore count decreased due to increasing P fertilizer application. With increasing fertilizer doses, soil organic C and N increased as well. It was concluded that since plants grow better with high P doses application, it may have a positive impact on organic matter (OM) remaining in the soil and increased soil C and N concentration.
