Enhancing mineral nutrient availability and corn productivity with biostimulants
Corn (Zea mays L.) production has greatly increased since corn was first domesticated some 7,000 years ago (Beadle, 1980). Generating improved cultivars with novel breeding schemes and genetics in combination with enhanced management factors and technologies has resulted in the highest corn grain …

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 …

Influence of nitrogen, reduced irradience and biostimulants on turfgrass growth, superoxide dismutase content and chlorphyll fluorescence
Biostimulants (BIOS) are non-mineral substances that, when exogenously applied in very small quantities, stimulate the metabolic activity of plants. Past research with biostimulants has not included differing levels of nitrogen fertility or shade as variables. The research presented was designed to …
