Producción y valor nutricional del forraje de soya en condiciones tropicales adversas Enrique Villalobos Carlos Tobía Agrociencias trópico húmedo Forraje de soya composición química costos de producción producción de biomasa Una parcela de soya (Glycine max L. Merr.var. CIGRAS-06) de 2,4 ha, cultivada en condicionesde alta precipitación y temperatura y en unsuelo ácido (pH 4,78) con baja fertilidad, en La Virgende Sarapiquí, produjo un promedio de 4,8 t ha-1de materia seca, cuando la planta entera se cosechópara forraje en el estado de desarrollo R6 (semillasllenas). Esta productividad es baja, en comparacióncon la obtenida en Guanacaste y San Carlos, dondelas condiciones de clima y suelo fueron favorablespara la producción de esta especie. La composiciónquímica de la planta entera fue de 20,2% deproteína, 6,7% de grasa, 5,5% de cenizas, 42,2%de fibra detergente neutro y 25,4% de carbohidratosno fibrosos. La proporción del peso seco de lashojas: vainas+semillas:tallos+pecíolos de las plantasfue de 24:39:37, respectivamente. Un análisis económicode los resultados señala que la producciónde forraje y de ensilaje tal como fue ofrecido tuvoun costo de 0,02 y 0,03 US $ kg-1, respectivamente.Se pone en evidencia que aún en las condicionesadversas de clima y suelo donde tuvo lugar esta investigación,es posible aprovechar las cualidadesnutricionales de la soya en la alimentación del ganadolechero, a un costo relativamente bajo y sinlos inconvenientes y la alta inversión en maquinariay equipo que representa la producción de soyapara semilla en el trópico húmedo. 2004 artículo científico 0377-9424 https://www.redalyc.org/articulo.oa?id=43628102 es http://www.redalyc.org/revista.oa?id=436 Agronomía Costarricense application/pdf Universidad de Costa Rica Agronomía Costarricense (Costa Rica) Num.1 Vol.28
