Efecto de diferentes poblaciones de maíz (Zea mays) en la producción de raíces de yuca (Manihot esculenta) al cultivarlos en asocio. I. Aspectos agronómicos

Maize (cv Tit-weft PB-C7) was intercropped with cassava (cv. Valencia) to assess the effect of different maize populations on cassava root yield with two levels of fertilization. The experiment was conducted at Turrialba (9°53' Lat. Nand 83°39' Long. W), Costa Rica at approximately 600 ma...

Levels of fertilization did not significantly modify this tendency to decrease cassava yields as maize population increased However total number of roots was higher at the low levels of fertilization as maize population increased from 1 up to 5 plants. Maize yield increased as a response to its planting density. At the high level of fertilization and according with the Total Relative Yield Index, cassava intercropped with 5 plants M-2 was the most efficient in terms of land use. At the low level of fertilization, cassava associated with 2 plants in was most efficient. 2022-09-12T22:26:39Z 2022-09-12T22:26:39Z 1983-04 Artículo https://repositorio.catie.ac.cr/handle/11554/11996 openAccess es Turrialba; Vol. 33, no. 2 8 páginas application/pdf Instituto Interamericano de Cooperación para la Agricultura (IICA)
