Abstract :In order to evaluate the effect of different levels of Phosphorous insert ignore into journalissuearticles values(P); alone and in combination with Humic acid insert ignore into journalissuearticles values(HA); on the yield and P accumulation by wheatinsert ignore into journalissuearticles values( Triticumaestivum L, CV Fakhr-e-Sarhad);., a field experiment was carried out at agriculture research station of Swabi, Pakistan during 2016-2017. A total of eight treatments replicated four times were arranged in Randomized Complete Block Design insert ignore into journalissuearticles values(RCBD); in the field. Two levels of HA including control insert ignore into journalissuearticles values(H0: control and H1: 500 g ha -1 ); and four levels of P insert ignore into journalissuearticles values(P 2 O 5 ); including control as Single Super Phosphate insert ignore into journalissuearticles values(SSP);   insert ignore into journalissuearticles values(P0: control, P1: 60 kg ha -1 , P2: 90 kg ha -1 , and P3: 150 kg ha -1 ); were utilized. ; Size of each plot was kept to 5x4 m. Addition of different levels of SSP alone and in combination with HA significantly insert ignore into journalissuearticles values(P<0.05); improved straw, grain and total wheat yield over control. HA in combination with 60 and 90 kg P 2 O 5 ha -1 improved the grain yield by 22.4 and 6.5 % respectively as compared to the same amount of fertilizer applied alone. Total yield insert ignore into journalissuearticles values(Dry mass + Grains); of 20877 kg ha -1 was produced by the treatment P2H1 insert ignore into journalissuearticles values(90 kg P 2 O 5 ha -1 + 500 g ha -1 HA); followed by the treatment P2H0, which were 78.69 and 75.03 % increases over the control. Significantly highest 1000- grain weight of 47.8 g was recorded in the treatment P2H1 while all other treatments showed non-significant increase in 1000- grain weight. Unlike soil pH values, improvement in the Soil Organic Matter content insert ignore into journalissuearticles values(SOM); was observed with the application of both HA and chemical fertilizers either applied alone or in combination. SSP applied either alone or in combination with HA increased significantly insert ignore into journalissuearticles values(P<0.05); the post-harvest soil P concentration as well as P accumulation by wheat plants over control. Results suggest that application 90 kg P 2 O 5 ha -1   reinforced with HA insert ignore into journalissuearticles values(P2H1); may be considered as an optimum dosage for achieving optimum yield of wheat crop.
