Emphasis is placed on the usefulness of statistics in analyzing exptl results. Definitions are given of basic concepts and terminology. The designs most frequently used in cassava expt are completely randomized, randomized complete blocks, split plots and systematic (response surface, fan-shaped ...

Utilizacion de la estadistica y el diseno experimental en investigacion en yuca
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...

Efecto de la epoca de siembra y edad de cosecha en el rendimiento de yuca
Research results obtained by the Cassava and Swine programs at the Instituto Colombiano Agropecuario are discussed. Low HCN var. should be used for swine feeding; the most promising var. is Llanera, which can yield 78 t/ha/10 mo and has a high crude protein content (7.25 percent). Balanced diets ...
La Colorada, on the North Coast of Colombia, was chosen by CIAT to study new technology validation in cassava. Trials measured the productivity of improved cassava production technology under actual field conditions, defined factors limiting cassava yields that may have been overlooked in the des...
A socioeconomic study was conducted on cassava cultivation and starch production in Cuatro Esquinas, Cauca (Colombia). The area is characterized by small landowners, with a cheap supply of labor, 2 rainy seasons, temperate climate, with cassava and coffee as the 2 most important cash crops. Twent...
The objectives of a cassava program in Ecuador are listed: the development and introduction of a simple technology that, without high inputs, allows the national av. yield to be increased; the economic, commercial production of cassava on acid, infertile soils of E. Ecuador (Amazonic region); and...
This is an overview of the present status of cassava as regards production and yields, nutritional value and international research programs. A cassava research program to be developed by CIAT is presented. The program covers the following areas: varietal improvement, production systems, internat...

The results are given of physicochemical analyses of soils and estimated cassava yields for five production zones in Colombia. There was little correlation between yield and the factors studied. Yields tended to increase as P increased; and there was a positive response to K in 2 zones and Ca/Mg ...

For the biological control of Ernnyis ello, an application of Bacillus thuringiensis (400-500 g/ha for aerial applications or 2-3 g/l of water for land applications), together with a surfactant with adherent properties, is recommended. When a hornworm population increase is foreseen due to the in...
