Abstract

This study was conducted to obtain field data on the growth and yield of sweet potaotes in elevated levels of carbon dioxide (C02 ) , Sweet potato plants were planted in open-top chambers as well as in open field plots. The plants were grown at ambient CO2 with and without chambers, ambient +75, +150, and +300 ppm (90 days). Enriched CO2 concentration increased the number of tubers and the percentage of dry matter of the tubers. The density, length and diameter of the tubers did not vary significantly in enriched CO2 levels. ----- Este estudio se llevrf a cabo con el objeto de obtener informacion sobre los ensayos relacionados con el desarrollo y la produccidn del camote con niveles altos de dioxido de carb6n' (C02 ) Los camotes fueron plantados en camaras sin techos, como tambien, se los cultivo' en parcelas de campo. Las plantas fueron cultivadas al ambiente C02, en camaras y fuera de elias, arnbiente +75, +150 y +300 ppm (noventa dias). Una concentraci6n mas fuerte de C02 incremento el numero de tuberculos, La densidad, ellargo y el diimetro de los tuberculos no vario significativamente en niveles altos de C02.
