Field experiment was conducted in winter season of 2016-17 and 2017-18 at PAU, Ludhiana to assess the impact of different irrigation methods on microbial activity and symbiotic traits in chickpea (Cicer arietinum L.) variety PBG-5. Five types of irrigation treatments were applied as drip irrigation in crop grown on plain (T1), drip irrigation in crop grown on ridges (T2), flood irrigation (T3), furrow irrigation(T4) and rainfed (T5). Symbiotic traits as number of nodules per plant and dry weight of nodules were recorded non significant among irrigation treatments (T1 to T4) but was significantly more than rainfed treatment (T5) whereas leghaemoglobin content of nodules was found significant among irrigation treatment and recorded more in drip irrigation treatments. Microbial population of bacteria and Rhizobia was found non-significant but population of fungi and p-solubilizer bacteria and dehydrogenase activity was significantly higher in T1, T2 and T4. Significantly higher yields were found in drip irrigation treatments with maximum values under T1 in both years and minimum values were observed under T5. Drip irrigation positively impacts symbiotic traits and microbial activity which leads to better growth and yield.
