dc.description | The effects of clean- and strip-cultivation, and of applications of coffee pulp, grass, and balck-plastic mulches under rows of heavily fertilized, young, intensively managed, strip-cultivated coffee growing in an area with a marked dry season were determined. Mulching with coffee pulp or grass increased soil water available to the coffee trees during the dry season and sharply reduced surface soil temperatures. The treatments had no marked effect on foliar composition of the coffee trees. Mulching with coffee pulp increased yields of strip-cultivated coffee over 3 bearing years from an average of 873 to 1,383 pounds of market coffee per acre yearly, but mulching with grass or black plastic did not affect yields. Strip-cultivated coffee produced as high yields as did clean-cultivated coffee. Yields of mulched coffee varied more widely from year to year than did those of clean or strip-cultivated coffee. Applications of coffee pulp as a mulch may be warranted on limited acreages of young, intensively managed coffee growing in full sunlight, particularly in regions with a marked dry season. Other mulch material is not readily available in the Coffee Region. | en-US |
dc.description | En un experimento con cafetos jóvenes, manejados intensivamente a pleno sol, se compararon los efectos del cultivo limpio, del cultivo en franjas, y del uso de las aplicaciones de pulpa de café como cubierta, de cubiertas plásticas y de cubiertas de yerba picada, bajo las hileras de cafetos. El uso de la pulpa o de la yerba como cubiertas, aumentaron la humedad disponible para los arbustos durante la época de sequía y además disminuyeron la temperatura de la superficie del suelo. Sin embargo, estas cubiertas no alteraron la composición química foliar de los arbustos. El uso de la pulpa como cubierta aumentó los rendimientos durante 3 años consecutivos, de un promedio anual de 875 a 1,383 libras de café pilado por cuerda. La cubierta plástica y la de yerba picada no tuvieron efecto alguno sobre la producción. La siembra en franjas produjo rendimientos similares a los del sistema de cultivo limpio. Se observó una variación mayor en la producción anual de las parcelas con cubiertas de pulpa, de yerba o plásticas, que en los sistemas de cultivo limpio o en franjas. El uso de la pulpa de café como cubierta parece aconsejable solo en extensiones limitadas de cafetos jóvenes cultivados intensivamente a pleno sol, especialmente en aquellas áreas con períodos de sequía definidos. | es-ES |
