Field experiment was conducted during Kharif and Rabi seasons of 1996-97 and 1997-98 at JNKVV, Regional Agriculture Research Station, Sagar (M.P.). Results revealed that higher level of phosphorus (@60 kg P2O5/ha) with FYM (@4 tonnes/ha) produced highest seed yield of Soybean during both the years (21.35 and 21.52 q/ha, respectively). As regard wheat production, the residual effect of phosphorus and FYM was prominent during 1996-97, even 4 tonnes FYM/ha without phosphorus also gave wheat yield at par to treatment consisted 60 kg P2O5/ha + 4 tonnes FYM/ha. On the basis of mean yield of various treatments 60 kg P2O5/ha + 4 tonnes FYM/ha produces highest grain yield (24.22 q/ha) followed by 30 kg P2O5 + 4 tonnes FYM/ha (22.91 q/ha), 60 kg P2O5/ha + 0 kg P2O5 FYM/ha (22.80 q/ha) and 0 kg P2O5/ha + 4 tonnes FYM the (22.66 q/ha) as compared to control. Direct effect of phosphorus also influenced grain production of wheat significantly during both the years and produced grain yield of 20.53 and 27.89 q/ha respectively.
