In field study, total 36 treatment combinations consisting of three moisture regimes as main plot treatment and 12 combinations of two levels of FYM, three levels of P carriers as sub-plot treatments evaluated in split plot design with three replications using wheat variety GW-451 as test crop. The results revealed that the maintenance of moisture between 100 and 75 % available water content (W1) significantly increased the length of earhead, number of grains/earhead, 1000-grain weight, grain and straw yield as well as gluten content. The treatments W1 and W2 resulted in 22.11 and 18.45 per cent higher grain yield as well as 23.56 and 19.91 per cent higher straw yield, respectively over W3 treatment. Whereas, maintenance of soil moisture between 100 and 25 % AWC (W3) resulted significantly higher P content in grain and straw of wheat. Application of phosphorus @ 90 kg P2O5 as MAP with 10 t/ha FYM (P3S1M1) gave significantly higher length of earhead, number of grains/earhead, 1000-grain weight, grain yield and application of 60 kg P2O5/ha as DAP with 10 t FYM/ha registering 4660 kg/ha grain yield which was at par with P3S1M1 while, Treatment combinations P3S2M1 showed significantly higher P content in grain and straw, but it was at par with P3S1M1 and P2S2M1. While significantly the highest P uptake by grain, straw and total P uptake by wheat was recorded by P3S1M1, but it was at par with P2S2M1. The interaction W2 × P3S1M1 recorded maximum length of earhead (11.09 cm), number of grains/earhead (68), 1000-grain weight (73.18 g), grain (5210 kg/ha) and straw (11969 kg/ha) yield of wheat and gluten content (39.42 %) in grain. The lowest value for bulk density (1.61 Mg/m3) and the highest value for maximum water holding capacity (22.49 %) of soil after harvest were recorded by P2S1M1. Treatment combination P1S2M1 recorded significantly higher available N (177.30 kg/ha), P2O5 (40.7 kg/ha) and K2O (207.57 kg/ha) in soil after harvest.
