Chickpea is a major legume crop grown in the semi-arid tropics and its yields are adversely affected by salinity. In this study, 55 rhizobacterial isolates obtained from the chickpea rhizosphere soil were screened for their salt tolerance. At 3% NaCl concentration, 41.8% rhizobacterial isolates formed colonies varying from 0.5-10 mm size and only 10.9 per cent isolates showed growth at 4% NaCl concentration. Significant growth on ACC supplemented medium plates was observed in 32.7% rhizobacterial isolates. Coinoculation studies with ACC + as well as ACC -Mesorhizobium and rhizobacterial isolates were made on chickpea under chillum jar conditions containing sloger's broth with salt (EC, 4dS/m) and without salt. Coinoculation of Mesorhizobium isolate MBD26 (ACC + ) and rhizobacterial isolate RHD18 (ACC + ) formed 59 nodules/plant and caused 112.9% increase in plant dry weight as compared to uninoculated control plants at 50 days of plant growth, whereas in the presence of salt, only 31.2% increase in plant dry weight was observed in comparison to uninoculated plants. At 80 days of plant growth, coinoculation of Mesorhizobium isolate MBD26 (ACC + ) with rhizobacterial isolate RHD18 (ACC + ) further increased the nodule number (78 nodules/plant) and 141.9% increase in shoot dry weight was observed as compared to uninoculated plants. Thus, it was concluded that coinoculation of ACC + Mesorhizobium and rhizobacterial isolates showed more stimulatory effect on nodulation and plant biomass under normal and salt amended treatments.

Rhizobacteria belonging to Bacillus sp. were isolated from the rhizosphere of chickpea (Cicer arietinum). Ten Bacillus strains were studied for their antifungal activity, effect on seedling emergence and plant growth promotion. Two Bacillus strains CBS127 and CBS155 inhibited the growth of all the four pathogenic fungi tested on nutrient agar medium plates in vitro. Seed inoculation with different Bacillus strains showed stimulatory effect on root and shoot growth at 10 d of observation in comparison to control whereas four Bacillus strains CBS24, CBS127, CBS129 and CBS155 caused retardation of shoot growth at 10 d. Maximum nodule-promoting effect was observed with Bacillus strains CBS106, CBS127 and CBS155. The symbiotic effectiveness of Mesorhizobium sp. Cicer strain Ca181 was further improved on coinoculation with six Bacillus strains i.e. CBS9, CBS17, CBS20, CBS106, CBS127 and CBS155 at 80 d of plant growth under sterile conditions and shoot dry weight ratios increased 1.62 to 1.74 times those of Mesorhizobium-inoculated treatments, suggesting the usefulness of introduced rhizobacteria in improving crop productivity.

Mung bean (Vigna radiata L.), also popularly as green gram, is an ancient and well known legume crop in Asia. A little information is available about the impact of bio inoculants application for improving growth of different cultivable varieties of green gram. Thus, the aim of this study was to assess the influence of Pseudomonas and Rhizobium as single and dual inoculants to promote the growth and nutrient uptake in green gram. Evaluation of bacterial bioinoculants for plant growth promotion and nutrient uptake in six cultivable varieties of green gram (MGG347, LGG460, ML 267, MGG 296, LGG 40 and TM 96.2) by selecting two plant growth promoting rhizobacterial isolates of Rhizobium-IC 3195 and Pseudomonas-P17 was done. Preliminary screening for various PGPR traits showed both the isolates were positive for production of IAA, HCN, siderophore, ammonia, biofilm, phosphate solubilization. A pot experiment was conducted with single and double inoculants of test isolates on six varieties of green gram for 75 days. After 75 days of sowing, plants agronomical and nutrient parameters were recorded as indicative parameters of plant growth promotion. The outcome of this investigation showed that the combination of Pseudomonas and Rhizobium influenced plant growth promotion most efficiently in plant varieties viz., MGG347, LGG460, ML267, MGG296, LGG40 and TM96.2. No one particular treatment could promote the growth of a given variety in all aspects studied. It was observed with these studies that the ability of a strain or combination of bioinoculants to promote growth of green gram plants varied with change in cultivable variety. This could be due to variation in the rhizosphere dynamics of a given bacterial isolate which in turn could be because of the change in the root exudates of a given plant. However, it was found that the combination of Pseudomonas and Rhizobium can be a viable, low-cost, effective alternative for improved growth and nutrient uptake in green gram.
