“…Salinity stress negatively impact photosynthetic activity in maize (Sali et al, 2015). Therefore, the use of PGPR as bioinoculant to enhance chlorophyll content in maize under saline condition is promising to mitigate salt stress (Ullah & Bano 2105).…”

A field experiment was conducted to investigate the effect of PGPR inoculation on growth and yield of maize as well as on reclamation of saline sodic soil of Soil Salinity Research Institute Pindi Bhattian Pakistan, during 2015-16. Seed of maize genotype "Islamabad Gold" were soaked (2-3 h) prior to sowing in the broth culture of 4 bacterial strains i.e. Pseudomonas putida (accession no. KX580766), Pseudomonas fluorescens (accession no. KX644132), Exiguobacterium aurantiacum (accession no. KX580769), Bacillus pumilus (accession no. KX580768) and Lysinibacillus sphaericus (accession no. KX580767). In vitro analysis of bacteria confirmed that they metabolize ACC deaminase, solubilize insoluble phosphate and produce significant quantity of auxin in the presence of L-tryptophan. Inoculation of maize with bacteria along with application of 1L inocula / treatment in the field gave a significant (P = 0.05) increase in germination (76%), leaf chlorophyll (24%), proline (65%), anthocyanin (38%) and soluble sugar content (56%). P. putida inoculation resulted in maximum increase in plant height, leaf area, no of grains cob -1 (459.8), 1000 grain weight (330.9 g) and grain yield (3.25 tha -1 ). P. fluorescens was least effective. The rhizosphere soil analysed after harvesting exhibited significant decrease in electrical conductivity (49%), sodium absorption ratio (98%), and cation exchange capacity (94%) concomitant with a significant increase in organic matter (52%), NO3-N (37%), available P (48%) and K (31%). The highest efficiency of P. putida may be attributed to the maximum ACC deaminase activity, higher production of indole acetic acid and greater potential for Phosphate solubilization. The favorable effects of PGPR were more pronounced in the successive year 2016.

“…These phytotoxic compounds mostly contained phenolics that alter the soil structure and plant growth processes are significantly lowered due to altered soil quality. In addition to the phenolic compounds, salt concentrations also showed inhibitory effect on germination and seedling growth and this impact of salinity is highly dependent on type of genotype (Aliu et al, 2015). The reduction in maize seed germination, seedling growth and yield related parameters was also observed by Ouda et al (2008).…”

2017. Quantifying allelopathic effect of rapeseed on germination and seedling growth of maize under different salinity levels. Zemdirbyste-Agriculture, 104 (3): 259-266 AbstractBrassica species have been reported as having allelopathic effect, reducing seed germination and emergence of subsequent cereal crops when grown in a rotation. Therefore, laboratory and greenhouse experiments were conducted to determine the allelopathic potential of rapeseed (Brassica napus L.) on germination and seedling growth of maize (Zea mays L.) under different salinity levels. Laboratory experiment consisted of two factors including different plant parts (root, shoot, leaf and whole plant) and their various concentrations (0, 5, 10, 15 and 20 %). In a greenhouse experiment three factors were studied including different salinity levels (0, 4 and 8 %), crop residue concentrations (0, 2 and 4 %) and decomposition time (2 and 4 weeks). The experiment was laid out in a completely randomized design with factorial arrangement where treatments were repeated five times for germination experiment conducted in Petri plates and three times for soil bioassay experiment conducted in pots. The results showed that extracts of different plant parts could not affect the germination, while different concentrations showed significant effect on maize seed germination. The interaction of extracts of different plant parts with different concentrations significantly affected the growth. Root and leaf extracts at 5% concentration produced maximum root length, shoot length and plant dry weight as compared to other plant parts at other concentrations. For the second experiment or greenhouse experiment the results showed that neither plant parts nor decomposition period could influence germination significantly. However, salinity levels showed inhibitory effect on germination with increase in salt concentration. The rapeseed residue concentration of 2% with 4% salt concentration produced maximum plant fresh and dry weight. Rapeseed showed allelopathic potential on germination and seedling growth of maize, but this influence was decreased gradually with the increase of salinity.

Madura Salt Tolerance Corn (var. Duko and var. Elos) and Hybrid Corn (Sukmaraga and Anoman-1) were germinated on 0, 100, 200, 300 and 400 mM NaCl for 7 days. Then its planted by wick system hydroponic also on the same NaCl concentration for 14 days, conducted by using randomized block design with 4 replications. The results were all varieties couldn't germinated on 300 and 400 mM NaCl and Anoman-1 couldn't be germinated from 200mM NaCl. Duko had the highest value of Full Germination Percent (FGP), Mean Germination Time (MGT), Germination Index (GI), and Salt Tolerance Index (STI) at 200 mM NaCl. Sukmaraga had the highest value of height and shoot growth ratio of the seedling.
