Environmental
stresses such as drought, temperature, salinity, air pollution, heavy metals,
pesticides, and soil pH are major limiting factors in crop production because
they affect almost all plant functions. Soil salinization is a serious stress
condition causing major problem for crop productivity. To combat this salinity
stress, Plant growth promoting rhizobacteria (PGPR) is considered as
innovative, effective and ecofriendly approach. Plant growth promoting
rhizobacteria (PGPR) have various direct and indirect mechanisms which can be
correlated with their ability to form biofilms, chemotaxis, and the production
of exopolysaccharide, indole-3-acetic acids (IAA) and aminocyclopropane-1-
carboxylate (ACC) deaminase Investigations on the interaction of PGPR with
other microbes and their effect on the physiological response of crop plants
under different soil salinity regimes are still at an incipient stage. An
experiment was conducted to investigate the effect of PGPR on lowering down the
salt stress. Treatments were control (T₁), Salt tolerant isolate
KH-1 (T₂), Salt tolerant isolate KH-2 (T₃), Salt tolerant
isolate KH-3 (T₄), PGPR-I (Pseudimonas) (T₅), PGPR-II
(Azotobacter) (T₆). Rice was sown under saline conditions at Soil
Salinity Research Institute, Pindi Bhattian. With the inoculation of salt
tolerant PGPR, plant growth and yield was improved. Result showed significant
increase in plant height, biomass and yield over control. Inoculation of salt
tolerant isolate KH-2 produced maximum grain yield in rice (4267 kg/ha)
followed by PGPR-II and it was statistically significant from all other
treatments along with control. It is concluded that with the application of
salt tolerant isolate (KH-2), there is significant increase in rice production.
