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....

A series of studies were carried out in Brazil, on a regional basis, to determine how cassava can fit into the Brazilian agricultural economy in the future so as to assist the country in reaching policy goals (improved welfare of the rural community and increased availability of low-priced food)....
Se realizo una serie de estudios en Brasil, a nivel regional, para determinar el papel de la yuca en la economia agricola brasilera del futuro y ayudar a alcanzar las metas propuestas en las diferentes politicas (mayor bienestar de la comunidad rural y mayor disponibilidad de alimentos a bajo cos...
A brief analysis is made of colonization, price and commercialization, credit, research, and extension policies and their impact on agriculture in Paraguay. The present status of cassava consumption, production, and distribution is then reviewed to determine potential and projected demand. Time s...
Se hace un breve analisis de las politicas de colonizacion, precios y comercializacion, credito, investigacion y extension y su impacto en la agricultura paraguaya. Luego se revisa el estado actual del consumo, la produccion y la distribucion de yuca para determinar tanto la demanda potencial com...
Different aspects of cassava cultivation in Cuba are described, namely agroclimatic regions, climate, prevailing soils, area and production, production systems, clones, and uses. Although cassava is planted on marginal soils with little availability of irrigation, if any, yields have increased as...
Se describen diferentes aspectos del cultivo de la yuca en Cuba, a saber: regiones agroclimaticas, clima, suelos predominantes, area y produccion, sistemas de produccion, clones y usos. A pesar de que la yuca se siembra en suelos marginales con poca o ninguna disponibilidad de riego, los rendimie...
A general description is given of cassava. Data deal with geographical distribution, production, yields and nutritional value, varietal improvement, agronomic practices, diseases and pests. Research activities in cassava are also described. (CIAT)
Se presenta una descripcion general de la yuca. Los datos tratan distribucion geografica, produccion, rendimientos y valor nutricional, mejoramiento var., practicas agronomicas, enfermedades y plagas. Tambien se incluyen actividades de investigacion en yuca. (CIAT)
The factors affecting the quality of cassava roots were studied: var. and age of the plant; DM, starch, and sugar contents in the roots; cyanide contents in leaves and roots. Roots of bitter var. CMC-84 showed higher DM contents than those of sweet var. CMC- 40. Total and reducing sugar contents ...
Se estudiaron los factores que afectan la calidad de las raices como: var.; edad de la planta; contenidos de MS, almidon y azucares en la raiz; y contenidos de cianuro en hojas y raices. Las raices de la var. amarga CMC-84 presentaron mayor contenido de MS que la var. dulce CMC-40. Los contenidos...
The seventh testing cycle for promising CIAT selections under improved, low-input technology was completed in 1981 at 9 locations in Colombia. The overall av. yield of the trials was 8.5 t/ha/yr, which is nearly 3 times the national av. yield of 3-3.5 t/ha. Av. yield of local cv. was about twice ...
Advances in research of the soil and plant nutrition section of CIAT's Cassava Program in 1981 are given regarding symptoms of Ca and S deficiency, germplasm screening for adaptation to high acidity and/or low P; effect of fertilization (long-term fertility); level and time of K application; effe...
