Abstract


Maize (Zea mays L.) is a valuable and important crop throughout the world. It is used as food purpose for humans, feed for animals and raw material for agricultural industries. There are some serious problems that reduce the yield of the crops which include salinity, water logging and drought. Maize is very sensitive to salinity. Rhizobia are efficient to reduce the salinity effect by various mechanisms of actions. A growth room trial was conducted to check their efficiency for growth promotion of maize in controlled environment. Nodulation data of the isolates on the Lucerne crop has been collected which showed a significant increase in nodulation by rhizobial inoculation as compared to un-inoculated control. Glass jar trial for the evaluation of these strains for growth promotion of maize crop at different salinity levels (0, 6 and 8 dS m-1) was conducted in growth room of Soil Microbiology and Biochemistry Laboratory, ISES, UAF under control conditions. Data regarding growth parameters were collected after six weeks of sowing. Results showed a significant increase in plant height, shoot fresh weight, root fresh weight and root length by 22.54%, 52.5%, 48.57% and 45.64% respectively as compare to (un-inoculated) control. Hence, the above-mentioned results showed that growth promotion of maize can be significantly increased by the inoculation with Rhizobium strains under salt stress.

Key words: Maize, salinity, rhizobial isolate
