An experiment was conducted at Udaipur during kharif seasons of 2009 and 2010 on soybean crop involving
twenty seven treatments i.e. three levels (20, 30 and 40 kg P2O5 ha-1) and three sources (Single super phosphate or
SSP; phosphorus rich organic manure or PROM and di-ammonium phosphate or DAP) of phosphorus in main
plots and three plant growth regulators or PGRs (water spray, benzyl adenine 50 ppm and NAA 100 ppm) in sub
plots of a split plot design having three replications. Results revealed that 40 kg P2O5 ha-1, SSP and NAA recorded
significantly higher pooled grain and stover yield equivalent to 25.95 and 37.37; 25.12 and 36.23 and 24.23 and
35.73 q ha-1than their respective counterparts, respectively. The enhancements in grain and stover yields were
associated with significantly higher pooled nitrogen and phosphorus uptake (kg ha-1) equivalent to 243.96 and
24.79; 228.10 and 24.52 and 229.90 and 23.44 under 40 kg P2O5 ha-1, SSP and NAA, respectively. Significantly
higher pooled available soil N (298.24 kg ha-1) andP2O5 (25.99 kg ha-1) was recorded under 40 kg P2O5 ha-1 but
variations among different PGRs were indifferent. Significantly higher soil pooled soil N was recorded under
PROM (294.93 kg ha-1) but significantly higher pooled soil P2O5 was recorded under SSP (25.72 kg ha-1).
