ABSTRACT

In a field experiment on the response of chickpea to P levels from two sources with two
species of phosphorus solubilizing bacteria, the use of Bacillus megaterium and Bacillus polymyxa
along with DAP and Rock phosphate (RP) each @ 20 and 40 kg P2O5 / ha could significantly
increase the nodule dry weight, grain yield, straw yield and N and P uptake in chickpea. These
parameters were found maximum with DAP @ 40 kg P2O5 / ha along with B. polymyxa and with
B.megaterium. Use of RP @ 40 kg P2O5 / ha along with B. polymyxa and also with B.megaterium
was found identical to DAP @ 40 kg P2O5 / ha alone but inferior to DAP 40 kg P2O5 / ha +
B.polymyxa /B.megaterium for most of the parameters studied. P use efficiency (PUE) and
relative agronomic effectiveness (RAE) of both the sources were also increased due to inoculation
with both the P solubilizing bacteria inoculants. The maximum RAE (152.2%) was recorded
with DAP + B. polymyxa whereas maximum PUE was recorded with DAP @ 20 kg P2O5 / ha +
B. polymyxa inoculation
