“…Perhaps in this investigation, native soil nodulating bacteria were competitive and/or prevalent enough to overshadow any inoculum effect. Previous studies with these same chickpea cultivars demonstrated similar results in that nodule count, nitrogenase activity, and nodule DW were minimally affected by inoculum treatment (Bidlack et al, 2001). However, these same studies revealed that 'Sarah' produced more nodules and had higher nodule DW than 'ICCV-2' chickpeas.…”

“…Whole plants were removed by excavating roots and soil in a 10-cm core around the stem to the bottom of the pot. Roots and nodules were separated from plants and used to report results for nitrogen fixation (Bidlack et al, 2001). Any removed soil was discarded after shaking from roots and not returned to pots in order to avoid treatment contamination.…”

Chickpea [Cicer arietinum (L.)] cultivars 'ICCV-2' and 'Sarah' were studied along with a control, multistrain, TAL 1148, and TAL 480 Bradyrhizobium strains to determine the effect(s) of cultivar and inoculum on dry weight (DW) and nitrogen (N) content of the legume, as well as soil mineral N, DW, and N content of wheat [Triticum aestivum (L.) emend. Thell.] in a continuous wheat-legume rotation. Chickpeas were planted during the summer and harvested in the fall of 1992, 1993, and 1994. Vegetative growth from chickpeas was incorporated into the soil prior to wheat planting, and soil cores were taken at 35 to 48 d after chickpea harvests. Additional summer fallow treatments for the winter wheat part of the experiment received 0, 45, and 90 kg N ha −1 each year. Wheat plants were removed the following spring and stubble was incorporated into the soil before planting chickpeas in the summer. 'Sarah' chickpeas accumulated about the same or more shoot DW and shoot N compared to 'ICCV-2'; whereas 'ICCV-2' generally produced more pod DW and pod N compared to 'Sarah.' Inoculum had no significant effect on chickpea DW or N content. Wheat DW and N following legumes increased marginally after growing 'Sarah' chickpeas, as evidenced by higher values of some treatments. Only the multistrain or absence of inoculum in 'Sarah' chickpeas resulted in significantly greater wheat DW or N content compared to the fallow wheat receiving no added N fertilizer. The contributions from 'ICCV-2' chickpeas to wheat DW and N content were not significant. Soil mineral N, as well as wheat DW and N content, fluctuated or increased during this three-year study, which demonstrated some benefit from incorporation of chickpeas into a wheat-legume cropping system.

“…The results are in close agreement with Garg and Singla (2005). Nitrogenase activity generally increased with plant age or decreased at flowering stage (Bidlack et al, 2001). Dey and Srivastava (2006) reported significant increase in nitrite reductase activity with the increase in concentrations of gibberellic acid.…”

“…Both shoot biomass and N content of uninoculated plants were equivalent to those inoculated with a multistrain mixture or TAL1127 and TAL 1132 pigeon pea specific Bradyrhizobium. These results are consistent with a nearly complete lack of significant inoculum effects on nodule number, mass, and nitrogenase activity throughout growth as was previously reported (15).…”

Pigeon pea [Cajanus cajan (L.) Millsp.] cultivars, 'Georgia-1' and 'ICPL-87', were grown without inoculation and with Bradyrhizobium inoculation (multistrain, TAL 1127, or TAL 1132) to evaluate legume dry weight (DW) and nitrogen (N) content, soil mineral N, and subsequent wheat (Triticum aestivum L.) productivity. Pigeon peas were grown during summer and 'TAM 101' wheat was grown during winter, along with summer fallow controls fertilized with 0, 45, and 90 kg N ha 21 , in 36-cm diam. 20-L pots from 1992 to 1995. Representative pigeon peas were harvested in the fall and remaining plants were incorporated into the soil. Wheat was planted and soil cores were collected at 35 to 48 d after pigeon pea harvest. Wheat was harvested the following spring. Factors affecting DW and N content of both 897
