Short Communication: Response of wheat to phosphate and potash fertilizers in anewly developed tube well irrigated soil of Rodh Kohi

The present study was carried out to check the response of wheat to phosphate and potash fertilizers in a newly developed tube well irrigated soil of Rodh Kohi area of Dera Ismail Khan District. The seven treatments including Control, Phophorus (P) at 60, Phosphorus + Potassium (PK) at 60-30, 90-30, 90-60, 120-60 and 120-90 kg ha^-1 were used to check the response of different agronomic traits, yield and physico – chemical properties of soil. The experiment was laid out in randomized complete block design with three replications. Nitrogen was kept constant at 150 kg ha^-1. The results showed significant (p 0.05) influence of treatments on spike length, biological and grain yield while plant height showed non – significant response to these treatments. The maximum plant height (63.60 cm), spike length (10.87 cm), biological yield (2.68 t ha^-1) and grain yield (1.50 t ha^-1) were observed in PK at 120-60 kg ha^-1. Physico – chemical characteristics were non significantly affected by the application of treatments except SAR which was reduced from 13.67 to 10.33 in control and treatment receiving NPK at 150-120-90 kg ha^-1, respectively. The Phosphorus and Potash content of the soil was significantly increased by the application of various treatments.
