Impact of Seed Bacterization with PGPR on Growth and Nutrient Uptake in Different Cultivable Varieties of Green Gram

Abstract:
Mung bean (Vigna radiata L.), also popularly as green gram, is an ancient and well known legume crop in Asia. A little information is available about the impact of bio inoculants application for improving growth of different cultivable varieties of green gram. Thus, the aim of this study was to assess the influence of Pseudomonas and Rhizobium as single and dual inoculants to promote the growth and nutrient uptake in green gram. Evaluation of bacterial bioinoculants for plant growth promotion and nutrient uptake in six cultivable varieties of green gram (MGG347, LGG460, ML 267, MGG 296, LGG 40 and TM 96.2) by selecting two plant growth promoting rhizobacterial isolates of Rhizobium-IC 3195 and Pseudomonas-P17 was done. Preliminary screening for various PGPR traits showed both the isolates were positive for production of IAA, HCN, siderophore, ammonia, biofilm, phosphate solubilization. A pot experiment was conducted with single and double inoculants of test isolates on six varieties of green gram for 75 days. After 75 days of sowing, plants agronomical and nutrient parameters were recorded as indicative parameters of plant growth promotion. The outcome of this investigation showed that the combination of Pseudomonas and Rhizobium influenced plant growth promotion most efficiently in plant varieties viz., MGG347, LGG460, ML267, MGG296, LGG40 and TM96.2. No one particular treatment could promote the growth of a given variety in all aspects studied. It was observed with these studies that the ability of a strain or combination of bioinoculants to promote growth of green gram plants varied with change in cultivable variety. This could be due to variation in the rhizosphere dynamics of a given bacterial isolate which in turn could be because of the change in the root exudates of a given plant. However, it was found that the combination of Pseudomonas and Rhizobium can be a viable, low-cost, effective alternative for improved growth and nutrient uptake in green gram.
