Nitrogen fertilization effects on forage production and nutritive value of 4 tropical grasses on alkaline soils in Argentina
This study evaluated effects of nitrogen (N) fertilization and gypsum application and their interactions on total pasture forage production and nutritive values of Chloris gayana cultivars ‘Santana’ and ‘Finecut’ and Panicum coloratum cultivars ‘Klein’ and ‘Bambatsi’ growing in a moderately sodic so...

| description | This study evaluated effects of nitrogen (N) fertilization and gypsum application and their interactions on total pasture forage production and nutritive values of Chloris gayana cultivars ‘Santana’ and ‘Finecut’ and Panicum coloratum cultivars ‘Klein’ and ‘Bambatsi’ growing in a moderately sodic soil (Typic Natracualf) in northcentral Santa Fe Province of Argentina over 3 years. Sown pasture forage production differed among cultivars. C. gayana cultivar ‘Finecut’ produced more forage biomass than the other 3 cultivars. P. coloratum cultivars were superior to C. gayana cultivars for nutritive value, showing lower NDF and ADF. N fertilization strongly increased forage production, total biomass and sown pasture biomass with improved crude protein content and improvement in plant N status. Addition of gypsum did not affect forage production and nutritive value. This research showed the feasibility to improve production and nutritive value of tropical pastures in subtropical areas by species/cultivar selection and N fertilization. |

Los objetivos de este trabajo fueron evaluar los efectos de la fertilización nitrogenada, el encalado y su interacción sobre la producción total de forraje y el valor nutritivo de cultivares de Chloris gayana ‘Santana’ y ‘Finecut’ y de cultivares de Panicum coloratum ‘Klein’ y ‘Bambatsi’ creciendo en un suelo sódico moderado (Natracualf típico) de la región centro-norte de la provincia de Santa Fe de Argentina durante tres años. Los cultivares difirieron en producción de forraje, siendo esta mayor en C. gayana ‘Finecut’ que en los otros tres cultivares. Los cultivares de P. coloratum fueron superiores en valor nutritivo a los de C. gayana por menores contenidos de FDN y de FDA. La fertilización nitrogenada aumentó fuertemente la producción total y de la pastura sembrada y mejoró el contenido de proteína y el estatus de nitrógeno en la planta. El encalado no afectó la producción forrajera ni el valor nutritivo. Esta investigación demostró la posibilidad de mejorar la producción y el valor nutritivo del forraje en áreas subtropicales mediante la selección de la especie/cultivar y la fertilización nitrogenada.
