Allelopathic research in past few decades has shown the feasibility of weeds and plant diseases management by allelopathic crop plants, plant residues, cultural manipulation, microorganisms as bioherbicides, and rhizobacteria. Inconsistency between the effectiveness of plant growth-promoting rhizobacteria (PGPR) to stimulate the plant growth and yield in the laboratory and the field has been reported. This inconsistency in the field results from PGPR applications can only be remedied through the improved knowledge of interplay between the host and introduced PGPR inoculant in the rhizosphere under field conditions. Application of biofertilizer reduced the quantity of chemical fertilizer used for maintaining threshold levels of crop productivity. We hope this review will stimulate further research in a holistic approach to solve the agricultural problems and achieve economically profitable and environmentally benign sustainable agriculture.
