Cassava is a low-priority crop in agricultural development policies in most L.A. countries, limiting active research and extension activities. A description is given of CIAT-generated low- cost technology that can increase yields. This package consists of the visual selection of planting material...
A trial was conducted on planting date and age at harvest at 2 exptl stations of the Instituto Colombiano Agropecuario -Carimagua (Meta) and Caribia (Magdalena)- to evaluate the physical production and quality of cassava produced under different climatic conditions and to identify a continuous pr...
Two trials were conducted at the CIAT expt station in Cali, Colombia, to measure the effect of spatial arrangement at fixed planting densities on cassava root yield. In expt I, 3 cassava cv. of different growth habit were planted at 10,000 plants/ha and arranged in 5 different patterns. Experimen...
Several cassava trials were planted at CIAT to study the effect of the maturity of stem cuttings, depth of planting, cutting length, planting position and the angle of the cut on root yield. Cuttings from the top and middle part of vigorous 1-yr-old plants produced greater than root yields than t...
Se sembraron varios ensayos de yuca en el CIAT para estudiar el efecto de la madurez de las estacas, profundidad de siembra, longitud de la estaca, posicion de siembra y angulo de corte de la misma, en el rendimiento de las raices. Las estacas de la parte media y superior de plantas vigorosas de ...
The low cassava yields obtained in L.A. at present are the result of a complex of problems: 1) deficient quality of planting material, which results in low sprouting, poor rooting and little initial vigor; 2) inadequate land preparation and planting systems; 3) control systems for pests and disea...
