In the present investigation, the effect of three beneficial organisms (root endophytic fungus Piriformospora indica (Pi) and pseudomonads strains R62 and R81) and their four different consortia (Pi+R62, Pi+R81, R62+R81, Pi+R62+R81) was investigated on the plant Vigna mungo through their inorganic carrier-based (talcum powder and vermiculite) formulations. All the treatments resulted in significant increase in growth parameters under glasshouse as well as field conditions and showed a consistency in their performance on moving from glasshouse to field conditions. In glasshouse conditions, a maximum increase of 4.5-fold in dry root weight and 3.9-fold in dry shoot weight compared to control was obtained with vermiculite-based consortium formulation of Pi+R81. In field studies using vermiculite as carrier, a maximum enhancement of 3.2-fold in dry root weight, 3.0-fold in dry shoot weight, 8.4-fold in number of nodules and 4.0-fold in number of pods in comparison to control was obtained with the bio-inoculant formulation containing consortium of Pi+R81. The same treatment also caused the highest improvement of 1.9-fold in nitrogen content and 1.7-fold in phosphorus content, while the highest increase of 1.4-fold in potassium content was obtained with Pi alone.
在本研究中，通过无机载体（滑石粉和蛭石）配方，研究了三种有益生物（根内生真菌梨形侧耳（Pi）和假单胞菌菌株 R62 和 R81）及其四种不同共生体（Pi+R62、Pi+R81、R62+R81、Pi+R62+R81）对绿豆（Vigna mungo）的影响。所有处理在温室和田间条件下均显著增加了生长参数，并在从温室到田间条件的过程中表现出一致性。在温室条件下，与对照相比，基于蛭石的 Pi+R81 共生体配方使干根重增加了 4.5 倍，干茎重增加了 3.9 倍。在田间研究中，使用蛭石作为载体，与对照相比，含有 Pi+R81 共生体的生物接种剂配方使干根重增加了 3.2 倍，干茎重增加了 3.0 倍，根瘤数增加了 8.4 倍，荚数增加了 4.0 倍。同一处理还使氮含量提高了 1.9 倍，磷含量提高了 1.7 倍，而单独使用 Pi 则使钾含量提高了 1.4 倍。
