Efficient use of adequate level of nitrogen (N), phosphorus (P) and potassium (K) is essential and important part of the sustainable agricultural production. P deficiency has been identified as one of the main limiting factors of crop production in various soils all over the world. The study was conducted to evaluate the response of wheat crop to phosphorus fertilization on acid vertisoil. Phosphorus was applied at the rate of 0, 30, 60, 90, 120 and 150 kg P 2 O 5 ha –1 along with a basal dose of N and K 2 O, at the rate of 80–60 kg ha –1 , respectively The experiment was to design a RCBD with four replications. Wheat variety „KG 56“ was sown at the test. The data of 1000–grain weight, grain and straw yield was recorded and grain and straw samples were collected and analysed for P–concentration. The results showed that 1000–grain weight, grain and straw yields significantly increased with each level of P 2 O 5 application up to 120 kg ha –1 and yield at 150 kg P 2 O 5 ha –1 remained at par with 120 kg P 2 O 5 ha –1 . Phosphorus concentration in grain and straw by wheat also significantly increased in all the treatments except control.
