| dc.description | A field experiment was conducted at Lajas Substation in order to study the effects of three irrigation and three nitrogen levels on dry-matter yields of Para grass, Guinea grass, and the mixtures of these grasses with tropical kudzu. Some plots were frequently irrigated when the average soil-moisture suction in the active root-zone reached 0.7 atm. and intermediately irrigated when the average soil-moisture suction in the active root-zone reached 2.0 atm. Nonirrigated plots were used as a check. The nitrogen levels tested were 0, 400, and 800 pounds of nitrogen per acre per year. | en-US |
| dc.description | En la Subestación de Lajas se llevó a cabo un experimento de campo para estudiar el efecto de tres distintos niveles de riego y tres de nitrógeno sobre la producción de materia seca de las yerbas Guinea y malojillo, y las mezclas de éstas con Kudzú tropical. Se regaron con frecuencia algunas parcelas cuando su promedio de succión (tensión) en el área en torno a las raíces alcanzó 0.7 de atmósfera, y se regaron con frecuencia intermedia cuando alcanzaron 2.0 atmósferas. Sirvieron de testigos las parcelas sin riego. Los niveles de nitrógeno fueron 400 y 800 libras por acre por año. Como testigos, se usaron parcelas sin aplicárseles nitrógeno. | es-ES |
