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...
Se llevó a cabo una serie de ensayos con yuca (Manihot esculenta Crantz). La tasa de crecimiento del cultivo aumentó proporcionalmente con el índice de área foliar (IAF) hasta un IAF de 4, y la tasa de crecimiento de la raíz aumentó basta un IAF de 3 -3,5 y luego disminuyó. El IAF se determina de...

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 ...
Analysis of previously published data shows that an extremely close correlation (r(2) = 0.83) exists between stomatal sensitivity to changes in leaf to air vapor pressure deficit and the maximum leaf conductance at low VPD in a wide range of plant species. The hypothesis is presented that stomata...

Two methods of rapid propagation of promissory cassava genetic material are described in detail: by shoots on 2-node stem sections and by single leaf-bud cuttings. (CIAT)
Se describen en detalle 2 metodos de multiplicacion acelerada de material genetico promisorio de yuca: el de retonos de estacas de 2 nudos y el de esquejes de una hoja y yema. (CIAT)
