Abstract:

Soil salinity hampers plant growth by disturbing the physiological and biochemical processes which ultimately result in decreased overall crop productivity. However, beneficial microorganisms have been reported to improve the fitness of plant under salt stress via their different direct and indirect mechanisms. Use of plant growth promoting bacteria (PGPB) has gained interest of plant scientists for their application as bioinoculants in modern agriculture. Some plant growth promoting bacteria (PGPB) are gifted with an enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase which facilitate plant growth under stressed conditions by regulating the stress induced hormone (ethylene) levels. We have developed bioinoculants for sustainable production of wheat from salt affected soils. These inoculants are multi-strain consortia of various species of PGPB which mainly have ACC-deaminase activity as well as salt tolerance abilities. Multistrain consortia for cereals are mixture of different salt tolerant PGPB strain having ACC-deaminase activity. These bioinoculants were developed in series of experiments conducted in laboratory, pots and fields and have been extensively evaluated under field conditions. The bioinoculants developed for wheat have shown their potential to substantial increase in grain yield on salt affected soils. There is a need to increase the reliability of these bioinoculants on farmers’ fields to build the confidence of farmers for adaptation of these bioinoculants as a regular input for crop production especially on salt affected soils.
