Cassava has been changing its role from a traditional fresh human food to an efficient crop for animal feed and starch production. Nearly all cassava is grown by small farmers. Harvested roots are sold to animal feed or starch factories, or are used for on-farm feeding of pigs to be sold at the m...


Kawano, Kazuo[The role of improved cassava cultivars in generating income for better farm management]The role of improved cassava cultivars in generating income for better farm management

During the past 16 years the Chinese Academy of Tropical and Agricultural Sciences (CATAS) has made good progress in developing improved cassava varieties for China. Several improved varieties have been released in south China, of which cv. SC124, with high yield and good cold resistance, is alre...

Different physiological characteristics of the cassava plant, which can be used as selection parameters, are reviewed, namely LAI, HI, biomass production, plants with amphistomatic leaves, and C4 photosynthesis. Experience indicates that it is better to select var. showing lower yield reduction u...

Se revisan diferentes caracteristicas fisiologicas de la planta de yuca que se pueden utilizar como parametros de seleccion: IAF, IC, produccion de biomasa, plantas con hojas amfistomatosas y fotosintesis C4. Se enfatiza que se debe tratar de seleccionar var. que presenten menor disminucion en co...


Cock, James H.El-Sharkawy, Mabrouk A.[Caracteristicas fisiologicas para la seleccion de yuca]Caracteristicas fisiologicas para la seleccion de yuca

This paper reviews published and unpublished information on the physiological and agronomic characteristics associated with the widespread adaptation of Brachiaria species. Adaptation to shade, drought, flooding, rainfall, and defoliation are discussed. Strong regrowth under frequent defoliation ...


Fisher, Myles J.Kerridge, Peter C.[The agronomy and physiology of Brachiaria species]The agronomy and physiology of Brachiaria species

Linking forest management to timber industry requirements is fundamental. Connections of silvicultural activities with wood quality are often limited to size-related characteristics, such as minimum DBH. Restrictions set by international markets (e.g. minimum log dimensions, heartwood content and...


Pérez Cordero, L.D.Kanninen, M.[Growth and timber quality of Tectona grandis in high input plantations of Costa Rica]Growth and timber quality of Tectona grandis in high input plantations of Costa Rica

Acacia Mangium Willd. is one of the most important tree species grown in commercial plantation in Monsoon Asia. Recently, the need for accurate information in the biomass in plantations has become more urgent, especially since the amount of carbon sequestered in afforestation/reforestation Clean ...


Hiratsuka, M.Toma, T.Yamada, M.Heriansyah, I.Morikawa, Y.[A general allometric equation for estimating biomass in Acacia mangium plantations]A general allometric equation for estimating biomass in Acacia mangium plantations

The accumulation and cycling of nutrients in planted forest is essential to the establishment of management practices that can lead to the sustainable production of the forest site. The uptake, accumulation and release of nutrients depend on tree age and stage of development. The knowledge of acc...


Silva, H.D. daFerreira, C.A.Bellote, A.F.J.[Quantification of the biomass and nutrients in the trunk of Eucalyptus grandis at different ages]Quantification of the biomass and nutrients in the trunk of Eucalyptus grandis at different ages

At two sites, where Eucalyptus grandis plantations were 7 and 12 years old, twelve dominant trees were cut and measured. The 12-year-old-trees were 29.4 m mean height, 19.9 cm diameter over bark and estimated volume 0.40 m3 tree-1. The 7 year-old trees were 30.7 m mean height, 20.6 cm diameter an...
