...d plant growth promoting rhizobacteria (PGPR) strains from maize rhizosphere. Different combinations of material were prepared using clay soil (35-50%), fly-ash (30-45%), press mud (5-15%) and lignite (5-15%). Clay soil (53% clay) was used for adhesion purpose but considering free of lump formation an important property of a good carrier, mixing 40% of soil with other material was found suitable. Using 40% of soil, six different treatments were formulated and ...

Present experiment was conducted under natural environment to evaluate the effect of PGPR on biomass production, nitrogen and proteins percentage of four mung bean varieties under different NaCI levels in sand culture after 5,7 and 9 weeks of sowing. Both inoculated and uninoculated plants were grown on mineral medium that were N...

Amelioration of Salt Stress in Cicer arietinum L. by Plant Growth Promoting Rhizobacteria

Nosheen Noor Elahi¹, Muhammad Shafique¹, Muhammad Imtiaz², Umer Farooq^3* and Muhammad Rashid¹

...e plant growth promoting rhizobacteria (PGPRs) play important role in eliminating the effect of salinity. Cicer arietinum L. is an important legume crop having high quantity of proteins. In the present study, four varieties (CM44, CM91, CM98 and CM2000) were grown in the presence and absence of PGPR inoculated media and nitrogen in different salinity levels (20, 50, 100, 200 and 300mM NaCl). The biomass production of the varieties CM91 and CM98 increased at 20...
