 ABSTRACT

Chickpea (Cicer arietinum L.) is the second most widely grown food legume crop after common bean. However, the productivity of chickpea has decreased to a significant extent since last two decades due to stressful conditions arising from unpredictable climatic conditions as well as saline nature of soil. Since last few years, studies on beneficial traits of actinomycetes regarding plant growth promotion and stress tolerance activities had opened new avenues for their applications in sustainable agriculture. In the present investigation, total 40 (AK1-AK40) actinomycete isolates were retrieved from different soil samples and chickpea nodules collected from CCS Haryana Agricultural University, Hisar farms and assessed for their stress tolerance abilities by determining salt tolerance potential and ACC utilization. Actinomycete isolates, AK3, AK6 (showing good growth upto 6% NaCl concentrations), AK11 and AK34 (showing good growth upto 5% NaCl concentrations) were observed to show good growth on ACC supplemented plates depicting their ability to utilize ACC which results in diminishing the ethylene levels and may play an important role in mitigating the stress conditions and improved productivity of chickpea.
