Effects of microbial biostimulants (Trichoderma album and Bacillus megaterium) on growth, quality attributes, and yield of onion under field conditions.

ABSTRACT: Microbial biostimulants (MBs) promote plant growth and stress tolerance in a sustainable manner. However, precise field trials of MBs are required in natural setting with a range of crop varieties to harness the benefits of biostimulants on crop yield improvement. This study investigated the effects of two MBs, Trichoderma album and Bacillus megaterium, on an onion cultivar's growth, nutritional qualities, antioxidant properties, and yield potentials under field conditions for two successive years. Before transplantation, onion bulbs were gelatin-coated with 2.0 and 4.0 g L^-1 of each of the MB. Results revealed that MBs-pretreated onion plants exhibited better growth indices, photosynthetic pigment contents, and yield-attributing features like bulb weight than cont
