| Summary, etc |
En un Inceptisol, suborden Tropepts, en Turrialba, Costa Rica, se estudio el efecto de 6 densidades diferentes de poblacion de maiz cv. Tuxpeno C-7 PB (0, 1, 2, 3, 4 y 5 plantas/m2) en el rendimiento de raices de yuca cv. Valencia (1 planta/m2), bajo 2 niveles de fertilizacion NPK: 120-200-150 (nivel alto) y 90-200-75 (nivel bajo) kg/ha. El no. total de raices, de raices comerciales y de raices/planta y el peso prom. de las raices disminuyeron significativamente al incrementar la poblacion de maiz. El rendimiento en peso total de raices y de raices comerciales de yuca disminuyeron linealmente a medida que aumento la densidad del maiz, hasta una disminucion max. de 50 por ciento con 5 plantas de maiz/m2. Los niveles de fertilizacion empleados no modificaron significativamente esta tendencia a disminuir los rendimientos de yuca a medida que la densidad de la poblacion de maiz aumentaba. Sin embargo, el no. de raices fue mas alto en los niveles bajos de fertilizacion a medida que la poblacion de maiz aumentaba de 1 a 5 plantas/m2. Los rendimientos de grano de maiz aumentaron segun el aumento en la densidad de siembra. A altos niveles de fertilizacion y segun el indice de rendimiento total relativo, la yuca asociada con 5 plantas de maiz/m2 fue la mas eficiente en terminos de uso de tierra. A bajos niveles de fertilizacion, la yuca asociada con 2 plantas de maiz/m2 fue la mas eficiente. (CIAT) |

| Summary, etc |
The effect of 6 different plant populations of maize cv. Tuxpeno C-7 PB (0, 1, 2, 3, 4, and 5 plants/m(2)) on the root yield of cassava cv. Valencia (1 plant/m(2)) was studied on an Inceptisol, suborder Tropepts, in Turrialba, Costa Rica, under 2 levels of NPK fertilization: 120-200-150 (high level) and 90-200-75 (low level) kg/ha, resp. The total no. of roots, commercial roots, and roots/plant, and the av. root wt. decreased significantly with increasing maize populations, with a max. of 50 percent yield reduction at 5 maize plants/m(2). The levels of fertilization used did not significantly modify this trend of reduced cassava yields with increasing maize plant populations. However, the no. of roots was higher at low levels of fertilization as maize plant population increased from 1 to 5 plants/m(2). Maize yields increased with increasing planting density. At high levels of fertilization and according to the total relative yield index, cassava intercropped with 5 maize plants/m(2) was the most efficient in terms of land use; at low levels of fertilization, cassava intercropped with 2 maize plants/m(2) was the most efficient.
