Tropical agriculture usually deals with severe limitations on management alternatives, arising from a combination of factors such as low-resource farmers, fragile lands, high pest susceptibility, etc. Under these conditions, agroecosystem properties other than productivity, such as stability, sus...

Measuring stability and degradability of agroforestry systems
A climate-smart agriculture (CSA) prioritization exercise in Western Kenya was carried out as part of the activities in the CIAT-led research project on ‘Climatesmart soil protection and rehabilitation in Western Kenya’, funded by GIZ. This project aims to encourage sustainable approaches to prom...

Prioritizing climate-smart agriculture practices in Western Kenya.
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 ...

CIAT cassava germplasm and its use in Asian national breeding programmes
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...
During 1981 genotype evaluation and selection continued at the ICA (Instituto Colombiano Agropecuario)-Caribia and the ICA-CIAT- Carimagua stations and at CIAT-Palmira, considered representative sites, resp., of (1) low-input technology with medium to high fertility soils in hot, lowland tropics ...
Durante 1981 se continuo la evaluacion y seleccion de genotipos en ICA (Instituto Colombiano Agropecuario)-Caribia, ICA-CIAT- Carimagua y CIAT--Palmira que son sitios representativos, resp., de tecnologias de 1) bajos insumos en suelos de fertilidad intermedia- alta en el tropico calido de tierra...
During 1981 the analysis of the potential adoption and impact of improved cassava production technology was continued at various levels and included: farm-level studies of the profitability of improved technology and constraints to adoption; analysis of costs of processing and marketing; and rese...
Durante 1981 se continuo el analisis de la adopcion potencial y el impacto de la tecnologia mejorada en la produccion de yuca en varios niveles se incluyo: estudios sobre la rentabilidad de tecnologia mejorada en fincas y limitaciones para la adopcion; analisis de costos de procesamiento y mercad...
Losses in root and planting material production caused by different pests as well as their biological control are evaluated. Studies of pests damaging dried cassava in storage were initiated. Biological aspects and form of attack of the following pests are described: stemborers (Lagochirus rogers...
