Abstract

Chickpea (Cicer arietinum) is one of the most significant legume crops and supply high-quality protein for human nutrition.Legume crops such as chickpea are important agriculturally because of their symbiotic ability to nitrogen fixation with specific soil bacteria. Legumes like chickpea depend on nitrogen provided by the activity to grow, but these rhizobium bacteria are affected by plant, parasitic nematodes that cause less activity and decrease the number of nodules in chickpea plant. The root lesion nematodes (Pratylenchus thornei) are common and economically important pests described as one of the limiting factors in agriculture and the growing chickpea field in the world. In this study, the effects of the is nematode on the number of rhizobia (nodules) and rhizobium bacteria activity were assessed in both wild and domest leafed accession of Cicer species under laboratory conditions. We inoculated all Cicer accession with the Mesorhizobium bacteria and with one species of the genus Pratylenchus (P. thornei). The result showed that P thornei has a negative impact on the number of nodules and the activity of rhizobium bacteria. Nematode infection on chickpea caused decreased nodulation. Overall, nematode infected plant formed 4-8 nodules/root and less nodule number than an uninfected plant.
