Activities of international cooperation during 1981 are listed. Training courses in cassava production, tissue culture, physiology, and in advanced research for postgraduate work were attended by 38 professionals from 16 countries. From 1973 to 1981 cassava hybrid seeds have been distributed in L...

The agricultural economy of Malaysia has traditionally been export-oriented. Cassava was the 1st of the export crops, established in the 1850s. Malaysia is a land-surplus, labor-scarce economy; thus cassava was planted in a shifting cultivation system giving it the image of a soil-depleting crop....
La economia agricola de Malaysia se ha orientado tradicionalmente hacia la exportacion. La yuca, uno de los primeros cultivos de exportacion, se establecio en la decada de 1850. Malaysia posee una economia con exceso de tierras y escasez de mano de obra; por tanto, como la yuca se producia en sis...

Malaysia: Cassava vs. tree crops in the competition for land
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 ...

In L.A., food uses determine the demand for cassava, especially in rural areas, because of problems in marketing this highly perishable crop. Production is stagnant due apparently to the lack of growth in demand. A significant growth market for cassava products is needed; e.g., the alcohol progra...
En America Latina, la utilizacion de los alimentos determina la demanda de yuca, especialmente en las areas rurales, debido a los problemas en el mercadeo de este cultivo altamente perecedero. La produccion se ha estancado debido a la falta de crecimiento de la demanda. Se necesita un significant...
Farmers have an intricate knowledge of their agro ecological domains. The empirical evidences from Kachorwa (terai) and Begans (mid-hill) sites in Nepal suggest that farmers distinguish domains for rice primarily on the basis of moisture and fertility. Farmers also differentiate the number, relat...

Cassava was probably introduced into China from South America around 1820. The main production area is in the southern province of Guandong and the Guangxi Zhuang Autonomous Region. With the catastrophic famines in the 60s, efforts to spread cassava cultivation northward intensified considerably....
