Values are the mean of 8 replicates. 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. DW = dry weight, Pt = P. trivialis, Pp = P. poae, Pf = P. fluorescens, and Psp = Pseudomonas
