Cassava is a high-yielding crop, well adapted to areas of the tropics with low, uncertain rainfall and mean temperatures above 20 degrees Celsius.It has the ability to grow on very acid soils where few other crops will grow atall; however, highest yields are obtained under more fertile conditions...
A trend exists for using natural dried cassava as an animal feed. However, the technology of cassava drying is not well developed. The rate at which cassava dries when placed in the open air depends on the drying system, the relative humidity, the air temperature and the wind velocity. Particles ...
CIAT has conducted research to develop a method for selecting drought-tolerant genotypes. Bean var. were planted during the dry season. Irrigation was suspended at the initiation of flowering in the dry treatment and the control treatment continued to be irrigated to avoid water shortage. During ...
Photoperiod insensitivity in the germplasm collection of beans (Phaseolus vulgaris) held at CIAT is found mostly in accessions from higher latitudes. Cold tolerance is found in accessions from the high Andes, but these are all photoperiod sensitive. A break in adaptation seems to occur at about 1...
Biological treatment, composting, in particular, is a relatively simple, durable and inexpensive alternative for stabilizing and reducing biodegradable waste. Co-composting of different waste sources allows to enhance the compost nutrient value. In particular, integration of ‘biosolids’ from the ...
By altering evapotranspiration and influencing how water is routed and stored in a basin, natural and agrarian ecosystems affect river flow. To quantify the impact of ecosystems on streamflow in two large river basins in Asia and Africa, simple statistical relationships were calculated, enabling ...
Description gemorphologique du Gourma malien suivie d'une etude climatologique, partic. la temperature, la pluviometrie, les precipitations et la secheresse avec apercu sur le mode de vie des populations de cette region.
Interpretation of results from this study is constrained by the low numbers of observations for each species-month-age-location subclass; by unequal numbers of observations per subclass; and by the confounding of treatment type with location. Nevertheless, it does contribute a considerable amount...
