A pot experiment was conducted to study the effect of P fertilization on available P status and yield of wheat and subsequent maize crops in different soils (twenty two from tarai and five from bhabar) of Uttarakhand. After harvest of wheat and maize crops the contents of available P in each individual soil under different treatments were in the order of P3>P2>P1>P0. The decrease under P0 and increase at each successively higher level was highly significant. The decline under control and buildup under P application did not differ appreciably between tarai and bhabar soils. On an average there was slightly more depletion in available P under P0 and slightly less increase under P1, P2, and P3 in tarai soils than in bhabar soils. The depletion in initial P present was greatest at P1 both in tarai (21.4 %) as well as in bhabar (26.0 %) soils. The influence of P application on dry matter yield of wheat was more pronounced at lower doses, however, it was significant at each successive level. The residual effect of P on dry mater yield of successive crop maize was also significant up to P3 level.
