Combination Effects of Rhizobium sp. and Nano-Fe on Growth, Nodulation, and Nutrient Uptake of Chickpea (Cicer arietinum L.)

The objective of this study is to investigate the effects of Fe Nano fertilizer and Rhizobium inoculation on nodulation, nitrogen fixation, and the plant growth of chickpea (Cicer arietinum L.). The soil samples were collected from the fields that were previously planted with chickpea. The study included testing the interaction influence of five levels of Nano Fe and three soil inoculation treatments using three replicates. The results indicated that Nano Fe application and soil inoculation rhizobium had a significant effect on plant growth number of seeds per plant and the seed protein content of chickpea. The plant height is greatly increased in the sterilizing process. The shoot height and root lengths of seedlings both increased significantly. The rhizobium bacteria have a positive impact on plant proteins and significantly increase the amount of protein in the plant. In conclusion, the results provided compelling evidence that the presence of Fe Nano fertilizer in nodules enhances nodulation and nitrogen fixation, improving the symbiotic performance between Rhizobium (chickpea) and the common bean plant.
