Emerging Role of Co-Inoculation of Pseudomonas with Cyanobacteria for Increasing Crop Productivity

The assessment of performances of the selected bacterial strain-NT1 (Pseudomonas sp.) and two cyanobacterial strains CB1 and CB2 (Desertifilum sp. and Leptolyngbya sp.) and their combinations were done in a field experiment with Pisum sativum and Cicer arietinum crop. Current study is the novel approach towards utilizing Desertifilum sp. for plant growth promotion. The study comprises of seven treatments along with controls. The enhancement in percent germination was recorded in treatments involving combination of bacterial cyanobacterial strains T5 (CB2+NT1) and T7 (CB1+CB2+NT1) with 90 and 94% in P. sativum while significant improvement in the fruit yield was obtained up to 63% in T7 (CB1+CB2+NT1) followed by 55% in T6 (CB1+CB2) with the same crop. Growth yield increased with T7 (CB1+CB2+NT1) over control by 230% in P. sativum while its rhizospheric soil analysis reveals enhancement in total nitrogen upto 130% compared to nitrogen content in control. The study with C. arietinum crop reveals significant increase in the fruit productivity by 48% with T7 (CB1+CB2+NT1) with increase of 117% of total nitrogen in T7 (CB1+CB2+NT1). Comparative evaluation revealed the superior performance of strain CB2 and NT1 over CB1 in increasing the growth and grain yield of crop and improving soil health.
