“…These results support the findings of present experiment. Higher chlorophyll content in plants in response to Rhizobium inoculation have been confirmed by other researchers (Matos and Schroder 1989;Yaman and Cinsoy, 1996). The better vegetative growth in plants inoculated by rhizobium strains because of better access to nitrogen sources could stimulate other growth characteristics like total chlorophyll content in leaves.…”

To study the effect of Rhizobium inoculation treatments (inoculation with strains number 133, 116 & their integrated application) and chemical nitrogen fertilizer application (based on soil analysis in form of Urea) on chlorophyll content and protein percentage of three common bean cultivars (viz. Bahman, Darkhshan and Sayyad) a field experiment was conducted at Agricultural Research Farm of College of Agriculture, University of Tehran (Karaj, Iran) during 2010 and 2011 growing seasons. The treatments arranged as factorial based on a randomized complete block design with three replications. The characteristics such as seed and leaf protein percentage, total chlorophyll content at flowering and podding stage were measured. The highest seed protein percentage of 28.02 was produced by Sayyad cv. when inoculated by rhizobium strain 116. The Darakhsan cv. treated with rhizobium strain 116 produced the highest leaf protein (27.67%) as compared to other fertilizing treatments. The highest total chlorophyll content (1.3 mg/gr) was measured in plants inoculated by Rhizobium strain 116. In response to an interaction effect, Drakhshan cultivar produced the highest total chlorophyll content (1.56 mg/gr) when treated by chemical nitrogen fertilizer. This could be explained by better access and easier nitrogen absorption in chemical nitrogen fertilizer treatment. The better vegetative growth in plants inoculated by rhizobium strains because of better access to nitrogen sources could stimulate other growth characteristics like total chlorophyll content in leaves. The results of this experiment suggest that application of rhizobium strains have the best effect on chlorophyll content and seed percentage.

“…1999) were higher in inoculated plots, the highest yielding strain HF 274 having the highest value following N application, although HF 177 had relatively lower value than the other strains. In other studies inoculated plants had greater amounts of chlorophyll than the uninoculated control (Matos and Schröder 1989, Yaman and Cinsoy 1996).…”

“…However, the results indicate that performance of the strains under laboratory or controlled environmental conditions may not necessarily be an indication of their performance under field conditions (Halliday 1984, Bremer et al. 1990), possibly due to their poor adaptation to actual field conditions and weak potential of competition with the native bacterial population in the field (Matos and Schröder 1989, Beck 1992), indicating the need for trials under field conditions. Previous trials clearly demonstrate that Rhizobium inoculation significantly increased chickpea yields in the absence of native soil Rhizobium population in the field.…”

A study was conducted in order to investigate yields in relation to seed inoculation of chickpea (Cicer arietinum L. cv. Aziziye-94) with eight Rhizobium leguminosarum ssp. ciceri strains isolated from wild chickpeas (C. anatolicum) of high altitudes (2000-2500 m) in comparison with standard bacterial culture, uninoculated control and mineral nitrogen fertilizer application in the growth room and in the field in 1999, 2000 and 2001 in Erzurum (29°55¢N and 41°16¢E at an altitude of 1850 m), Turkey.In the growth room trial, bacterial inoculations significantly increased shoot dry weight, N %, total N, N fixed and efficiency of symbiosis compared with the uninoculated control treatment depending on the strains. In the field trial, inoculations with HF 274 and HF 177 increased nodule dry weight, N %, chlorophyll, seed yield and total biomass yield depending on the strains, the lowest values being recorded in uninoculated plots. As an average of years, inoculation with HF 274, HF 177 and standard bacterial culture increased seed yields, respectively, by 23.3, 22.7 and 16.8 % over uninoculated control.In conclusion, rhizobial inoculation of chickpea with HF 274 and HF 177 strains isolated from wild chickpeas (C. anatolicum) of high altitudes may substitute costly N fertilizers in chickpea production even in cold highland areas such as Erzurum.

“…Rhizobia have been used in agricultural practices mainly for nitrogen fixation and plant growth promotion (PGP) [12][13][14] due to their wide distribution. The first criterion for a Rhizobium strain to be used in legume inocula is that it must be highly effective when fixing nitrogen [15].…”

Deciphering the Factors for Nodulation and Symbiosis of Mesorhizobium Associated with Cicer arietinum in Northwest India

The compatibility between rhizobia and legumes for nitrogen-fixing nodules and the stages of root hair curling, formation of infection thread, and nodulation initiation have been vitally studied, but the factors for the sustainable root surface colonization and efficient symbiosis within chickpea and rhizobia have been poorly investigated. Hence, we aimed to analyze phenotypic properties and phylogenetic relationships of root-nodule bacteria associated with chickpea (Cicer arietinum) in the north-west Indo Gangetic Plains (NW-IGP) region of Uttar Pradesh, India. In this study, 54 isolates were recovered from five agricultural locations. Strains exhibited high exopolysaccharide production and were capable of survival at 15–42 °C. Assays for phosphate solubilization, catalase, oxidase, Indole acetic acid (IAA) production, and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity revealed that all the tested isolates possessed plant growth-promoting potential. Metabolic profiling using Biolog plates indicated that patterns of substrate utilization differed considerably among isolates. A biofilm formation assay showed that isolates displayed a nearly four-fold range in their capacity for biofilm development. Inoculation experiments indicated that all isolates formed nodules on chickpea, but they exhibited more than a two-fold range in symbiotic efficiency. No nodules were observed on four other legumes (Phaseolus vulgaris, Pisum sativum, Lens culinaris, and Vigna mungo). Concatenated sequences from six loci (gap, edD, glnD, gnD, rpoB, and nodC) supported the assignment of all isolates to the species Mesorhizobium ciceri, with strain M. ciceri Ca181 as their closest relative.
