    Abstract
    Paraquat applied at early anthesis of soft chess and wimmera ryegrass increased protein retention significantly in the following dry season. The rates of paraquat required varied with growth stage, from 1/8 to 1/4 lb./acre to cure grasses and 1/4 to 1/2 lb./acre to cure rose clover and subclover. Curing grasses increased the protein retention of dry grasses only to the maintenance level of livestock. Seeding a legume is necessary to increase the summer protein above maintenance. Spraying with paraquat increased the protein retention of legumes to twice that needed for maintenance./Un estudio anterior demostró que la aplicación de "paraquat" en zacates anuales durante la antesis, aumentó el contenido de proteína de 57 a 77%, el fósforo a 9.125% y se redujo la fibra cruda a un rango de 2 a 4%. El presente estudio se llevo a cabo en los pastizales de California, incluyendo el secado de dos zacates y dos leguminosas, anuales ambas, a los que se les aplicó "paraquat" durante la antesis, dando como resultado un aumento significativo del contenido de proteína para la siguiente época seca. El contenido nutricional de los zacates fue a nivel de mantenimiento mientras que en las leguminosas aumentó al doble, recomendándose la siembra combinada de zacates y leguminosas para obtener más proteína. La cantidad de "paraquat" por acre, varía de acuerdo a la época de crecimiento de 1/8 a 1/4 lb. para zacates y de 1/4 a 1/2 lb. para las leguminosas.
