N and K applied as ammonium sulfate @ 240 kg N/ha, and muriate of potash @ 80 kg K/ha to all the treatments, respectively. TCP = tricalcium phosphate (120 kg P/ha). SSP = single super phosphate (120 kg P/ha). Values with common letters in each column do not differ statistically according to Duncan’s Multiple Range Test

at p ≤ 0.01. Pt = P. trivialis, Pp = P. poae, Pf = P. fluorescens, and Psp = Pseudomonas sp. The soil N content was significantly higher in five PSB treatments than NP0K, NPTCPK and NPSSPK and statistically at par among NP0K, NPTCPK and NPSSPK. The soil P content was significantly higher in three PSB treatments over NP0K, NPTCPK and NPSSPK. The highest available P content was obtained with NPTCPK+Pt BIHB745 among PSB treatments and with NPSSPK among uninoculated treatments. The soil K content was significantly higher in nine PSB treatments than other PSB treatments, NP0K, NPTCPK and NPSSPK. The highest available K was recorded for NPTCPK+Psp BIHB 756. The available Ca was significantly higher in three PSB treatments than other PSB treatments, NP0K, NPTCPK and NPSSPK.
