Weed control in Latin America is costly and heavily dependent upon herbicides. Often irrigated rice farmers spray herbicides in late post-emergence at 30 to 44 days after emergence (d.a.e.). The economic benefits from such late applications are often unclear. Two experimental approaches involving...
Research was conducted at the Centro Internacional de Agricultura Tropical (CIAT) in 1980 in order to solve the problem of low cassava yields in Loja, Ecuador, Objectives were: (1) to determine the effect of vertical and horizontal plantings of cuttings on the emergence and competitive vigor of c...
A total of four sets of seeds (totalling 5526 seeds) were recieved from CIAT during the period 1990-1993. One set (comprising 1100 hybrid seeds) originated from the Thai-CIAT program in Rayong. Evaluation and selection of seedling clones has progressed satisfactorily, and culminated in the releas...
A detailed review on cassava production in intercropping systems is given, based on the following aspects: selection of plant types for intercropping; realtive planting time, planting density and pattern (spatial arrangement); mineral nutrition and fertilization, competition for nutrients; pest, ...
A multisite trial (6 sites) was carried out to determine the optimum plant populations for one of the most important cropping systems used in the Lorica district (Cordoba, Colombia): maize associated with yam and intercropped with cassava. Plant populations of 1.2 x 1.0, 1.2 x 1.3, and 1.2 x 1.6 ...
Se realizo un ensayo multilocalizado (6 sitios) para determinar la densidad de poblacion optima del arreglo maiz asociado con name e intercalado con yuca, uno de los mas importantes en el Distrito de Lorica (Cordoba, Colombia). Se utilizaron densidades de poblacion de 1.2 x 1.0, 1.2 x 1.3 y 1.2 x...
The main results of research on different intercropping systems, including tobacco//cassava and yam x maize//cassava, are detailed. When cassava is intercropped with tobacco, tobacco yields are reduced by 24.3 percent but quality characteristics of leaves and no. of leaves/plant/harvest are not a...
Se detallan los principales resultados de investigacion sobre diferentes sistemas de cultivo intercalado, entre ellos tabaco//yuca y name x maiz//yuca. Cuando la yuca se intercala con tabaco, los rendimientos del tabaco se reducen en 24.3 por ciento pero no se afectan sus caracteristicas de calid...
