Plant growth regulators and biostimulants for use in varying management systems to improve corn grain yield
Plant growth regulators (PGRs) and biostimulants are product chemistries that have recently become popular in the agricultural market. There is no concrete evidence however, for their best place in a management system to optimize their return on investment and crop yield potential. The objective of …

Bioaugmentation and biostimulation of a South African coal-based Technosol as a mine rehabilitation strategy
… regulated biogenically through MR application as biostimulant for microbial respiration. Teff biomass production and inflorescence were favoured in warmer conditions as a result of accelerated microbial activities and photosynthesis. The effect of microbial inoculation was more evident during the …
