AU Merit Vicia villosa
AU Merit es ideal para pastoreo, heno y cultivos de cobertura. Es un productor de enormes cantidades de forraje que está listo a principios de año. También es un productor masivo de nitrógeno y perfecto para apoyar a los polinizadores y la vida silvestre.
Features
Madurez temprana
AU Merit es casi 15 días antes que la mayoría de los otros cultivares de vicia villosa. Cuando se usa como cultivo de cobertura, esto significa que existe más potencial de fijación biológica de N (BNF) para los cultivos plantados a principios de la primavera.
Vigoroso y adaptable
AU Merit fue diseñado para tener buena resistencia a las enfermedades, excelente vigor de las plántulas y tolerancia a una amplia gama de tipos de suelo.
Alto rendimiento de forraje
La madurez temprana de AU Merit también contribuye a su alta producción de forraje y aumenta el valor para el pastoreo temprano en la primavera.
Atrae vida silvestre / polinizadores
AU Merit proporciona a la vida silvestre y a los polinizadores abundante forraje y flores durante la temporada de crecimiento de primavera.
Nitrógeno abundante
En las pruebas, AU Merit mostró hasta 175 libras. de N / acre, superando a muchas otras leguminosas.
Nitrogen Studies
AU Merit was evaluated as part of an extensive cover crop nitrogen study conducted by North Carolina State University in 2008-2010. In this trial, AU Merit showed up to 175 lbs. of N/acre and direct positive grain yield contributions to the following corn crop.

Yield Data
AU Merit has shown its ability to produce abundant forage (12% or greater than many other varieties) and flower earlier. While AU Merit has been tested and used in numerous locations, data from Alabama, Louisiana, and Texas are worth noting.
Alabama
AU Merit has shown significant yields performance in multiple locations with yields exceeding other varieties by 11-22%.
Louisiana
AU Merit was planted on the LSU Winnsboro research farm. The trial was initially planted in late October. Due to extreme droughty conditions, it was replicated with another planting 25 days later at the end of November. The results shown in these data sets would indicate that AU Merit should perform well planted both early and late. Yield performance exceeded other varieties by up to 40%.
Texas
AU Merit outperformed other varieties up to 42% and showed very good regrowth in a double cutting. This trial also evaluated AU Merit with Nitro-Coat® and indicated an 18% boost in total dry matter with the Nitro-Coated® entry.

Cover Crop Performance
In the October of 2019, researchers with the University of Tennessee planted extensive cover crop trials in three Tennessee locations – Knoxville, Spring Hill, and Milan. In addition to assessments of nitrogen content and release, assessment were conducted for ground cover, biomass and height. The data below reflects averages of all three sites.
