We determined if application of certain naturally occurring compounds would stimulate emergence, growth, and development of carrot (Daucus carota L.). The commercially available biostimulants Agro-Lig, Enersol (humic acids), and Ergostim (folic acid) were added at a concentration of 1.5% (w/v) to Laponite 508 (magnesium sulfate) gel used in fluid drilling. Agro-Lig, Enersol and Ergostim increased carrot emergence > 2-fold as measured by number of roots as compared to untreated seed. Number of carrots increased 50% to 75% when biostimulants were incorporated into the gel, compared to fluid-drilled seed without the biostimulants. When biostimulants were applied as a drench over untreated seeds sown conventionally, the average root weight obtained was more than twice that from untreated seeds.

Yield responses of `Blue Vantage' cabbage (Brassica oleracea L.) to P fertilizer and two commercially available biostimulants—ROOTS and ESSENTIAL-were evaluated on soils very high in P fertility. Head yield was not increased with P fertilizer when cabbage was transplanted into soil with Mehlich-3 soil test P indexes ≥ 112 ppm (112 mg·kg-1). Neither of the biostimlants applied as a root drench at transplanting influenced head yield or plant tissue nutrient analysis.

A glycine-rich mixture of amino acids and short-chain peptides (Siapton) (3 g a.i. per L), two citokinin-rich seaweed (Ascophyllum nodosum) extracts (Stimplex and Triggrr) [50 mg·L-1, active ingredient (a.i.)], a mixture of cysteine and folic acid (Ergostim) (300 mg·L-1 a.i.), and a terpenic acid-rich Siberian fir (Abies sibirica) extract (Silk) (50 mg·L-1 a.i.) were sprayed on St. Augustinegrass residential turf at the beginning of the post-winter regrowth in Gainesville, North-Central Florida, to determine their effect on the growth and aesthetics of the lawn. Above- and belowground biomass, leaf color, and density in St. Augustinegrass were enhanced by all the biostimulants, as compared to untreated St. Augustinegrass plots. The best results were obtained, in descending order, with the cytokinin-rich seaweed extracts, the glycine-rich mixture of amino acids and short-chain peptides, the mixture of cysteine and folic acid, and the terpenic acid-rich Siberian fir extract.
