Abstract/Contents:"Organic fertilizers and protein/amino acid containing products have garnered interest in the turfgrass industry. Roquette is a company that produces fertilizers/biostimulants and other plant care solutions from plants such as corn, wheat, potato, and yellow pea via a process of progressive refining that extracts starch, proteins and other valuable ingredients. However, minimal research has been conducted on the effects of plant protein containing products on turfgrass growth. The objective of this study was to determine if plant protein products could be a potential fertilizer/biostimulants to improve turfgrass growth compared to urea. Kentucky bluegrass (Poa pratensis L.) was established in sand filled rooting tubes at the Charlie Hall Greenhouse at the Iowa State University (Ames, IA, USA). Treatments included: vegetable protein A, vegetable protein B, vegetable protein C, urea, and an untreated control. Treatments had a significant effect on percent green cover on all rating dates, and all root and shoot parameter measured at the conclusion of the study. Vegetable protein A and B resulted in greater percent green cover compared to urea on all rating dates. Vegetable protein C provided greater percent green cover than urea on seven of eight rating dates. Vegetable protein A, B, and C resulted in 57%, 49%, and 54% greater total root length compared to urea, respectively. Additionally, vegetable protein A, B, and C provided 83%, 84%, and 77% greater root surface area relative to urea, respectively. Furthermore, vegetable protein A (115%), B (138%), and C (100%) resulted in greater total root volume compared to urea. Vegetable protein A, B, and C also provided 200%, 243%, and 129% greater shoot biomass relative to urea. Overall, plant protein products could be considered a potential fertilizer to improve turfgrass growth (root and shoot) compared to urea."
