The combined application of rhizobial strains and plant growth promoting rhizobacteria improves growth and productivity of mung bean (Vigna radiata L.) under salt-stressed conditions

Field application of ACC-deaminase biotechnology for improving chickpea productivity in Bahawalpur

“…In case of combined application, in addition to the positive effects of P-enriched compost on soil physicochemical properties and crop growth, the bacterial strains present in the multi-strain biofertilizer enhanced the nitrogen and phosphorus availability, suppressed the possible negative effects of water shortage and improved root growth leading to improvement in yield and quality of chickpea. It has been well documented that promotion of root growth under stressed environment occurs due to decrease in ethylene levels by the ACC-deaminase activity of rhizobacterial strains (Shaharoona et al, 2006;Ahmad et al, 2012). Similarly, in previous study, it has been reported that PGPR inoculation increased the grain yield by suppressing the diseases (Vinale et al, 2008).…”

“…Among endophytic bacteria, Rhizobia make symbiotic associations with legume plants and help plants to grow vigorously through atmospheric nitrogen fixation and several other mechanisms. The ACC deaminase containing rhizobacteria in combination with Rhizobia have been well documented to improve the efficiency of Rhizobial inoculation especially under stressful environments (Ahmad et al, 2012(Ahmad et al, , 2013c) thus they can be excellent supplement to chemical fertilizers for improving crop productivity.…”

INOCULATION WITH Rhizobial consortium FOR IMPROVING THE GROWTH, YIELD AND QUALITY OF MAIZE UNDER SALT-STRESSED CONDITIONS

“…It might also be possible that high salts concentration have slackened the sap flux flow which have lowered the root hydraulic conductivity with a possible consequence of reduced relative water content (Vysotskaya et al, 2010). Improvement in RWC in response to single/multi-strain inoculation has been reported in many studies (Bano and Fatima, 2009;Ahmad et al, 2012).…”

“…The use of bacteria for improving crop growth and productivity under stress environments has been well documented Ahmad et al, 2011Ahmad et al, , 2012Ahmad et al, , 2013. Results of the present study revealed that salinity stress negatively affected all the attributes of maize plants.…”

“…Indirectly, rhizobia improve plant health by improving the self-defense of plant through induction of systemic resistant (Reddy, 2013) against harmful insects, pathogens, diseases and viruses (Huang and Erickson, 2007). Rhizobia have also been reported to improve the growth and yield of legumes (Ahmad et al, 2012;El-Akhal et al, 2013) and non-legumes (Afzal and Bano, 2008;Bano and Fatima, 2009) under salt stressed conditions. There are extensive reports of rhizobia for enhancement of number of primary roots, root proliferation, and plant growth promotion even under increased level of salinity (Naz et al, 2009;El-Akhal et al, 2013).…”
