Abstract

A field experiment was conducted to evaluate the effect of plant growth promoting microbial isolates on yield and quality of guava, during kharif season of 2019 and 2020 on Vertisol. The experiment was laid out in randomized block design with eleven treatments (Ten microbial isolate and one uninoculated control) and three replications. The laboratory stock cultures of microbial isolate (Bacillus subtilis, Bacillus lecheniformis, Bacillus megaterium, Bacillus thuringiensis, Pseudomonas fluorescens, Pseudomonas striata, Trichoderma viride. Trichoderma herzenium, Azotobacter chroococcum and Azospirillum lipoferum) selected and tested in field condition. Recommended dose of fertilizers is common for all treatments. In results it was observed that guava plant or row treated with treatment RDF+ Pseudomonas striata showed significant superiority in terms of number of fruits per plant, average fruit weight, yield and improved quality which was followed by RDF+ Trichoderma viride and RDF + Bacillus megaterium.

Conclusion

It is evident from the above Results discussion that the plant growth promoting microorganisms (bacteria or fungi) plays an important role in enhancing the crop productivity by various direct as well as indirect mechanisms. The effect of these microorganisms has been shown by various workers either using singly or in consortium of more than one type of microorganism and predicted that the dual inoculation of PGPR has showed better results as compared with the single inoculations. The present study with plant growth promoting isolates and guava crop revealed that inoculation with Pseudomonas striata along with RDF of NPK followed by Trichoderma viride and Bacillus megaterium were found considerably effective in enhancing growth, yield and maintaining quality of guava crop. These microbial isolates can be explored as bioinput for improving plant growth and also to correct the nutrients deficiency in guava.
