Beans are grown and consumed in all of the 34 districts of Uganda. Areas outside the highland and fertile crescent zones account for over 60 percent of the country's production. Increased production over the past 10 years has been through area expansion rather than increased yield. Production con...

El frijol se cultiva y consume en los 34 distritos de Uganda. Las areas fuera de las regiones montanosas y de la creciente fertil contribuyen con mas del 60 por ciento de la produccion del pais. Los incrementos de la produccion durante los ultimos 10 anos se han debido mas a la expansion de las a...


Male-Kayiwa, B.S.[Review of bean production in Uganda outside the highland and fertile crescent zones]Review of bean production in Uganda outside the highland and fertile crescent zones

The paper reviews cassava breeding and agronomy research carried out by MARDI over the 15-year period, 1984-1999. Evaluation of seedling clones derived from sexual seeds introduced from CIAT/Colombia and the Thai-CIAT program has culminated in the release of two varieties: Perintis (in 1988), whi...

In the 1st of 2 trials, 12 bean genotypes were planted during the rainy season (March) in Matapwata (Thyolo, Malawi). Highest yielding (kg/ha) genotypes were 25-2 (616.8), A286 (476.3), 8-7 (423.1), 29 x P692 (348.3), and 25-2 x 8-7 (306.6). Seed size, except for CIAT lines A286 and A344, varied ...

Se realizaron dos ensayos: en el primero se sembraron 12 genotipos de frijol en la estacion lluviosa (marzo) en Matapwata (Thyolo, Malawi). Los genotipos de mayor produccion (kg/ha) fueron 25-2 (616.8), A286 (476.3), 8-7 (423.1), 29 x P692 (348.3) y 25-2 x 8-7 (306.6). El tamano de las semillas, ...

Twenty-two bean genotypes were assessed in monoculture and in association with maize (NSCM 41) to identify germplasm genotypes from Bunda, Malawi, that synchronize maturity with the end of the growing season. Responses differed among the 3 trial sites (Ng'onga, Bunda, and Matapwata). In general, ...

Se evaluaron 22 genotipos de frijol en monocultivo y en asociacion con maiz (NSCM 41) para identificar genotipos del germoplasma de Bunda, Malawi, que sincronicen madurez con el final de la epoca de cultivo. Las respuestas difirieron entre los 3 sitios del ensayo: Ng'onga, Bunda y Matapwata. En g...

In 1985 3 new cv. (Frijolica 0-3.1, Frijolica 0-3.2, and Frijolica LS-3.3) were released as a result of collaborative research between the Instituto Colombiano Agropecuario (ICA) and CIAT. At the Centro Regional de Investigacion (CRI)-La Selva (Antioquia, Colombia), 190 new advanced climbing bean...

On-farm research activities in 1986 continued in the areas of training, network establishment, methodology adaptation, technology development on-farm, and technology adaptation to specific areas. One early result is a better understanding of the variability in the adaptation of the newly adopted ...

Las actividades de investigacion en fincas en 1986 continuaron en las areas de capacitacion, establecimiento de redes, adaptacion de metodologias, desarrollo de tecnologias a nivel de finca y adaptacion de tecnologias a areas especificas.

This paper reviews intercropping research for a particular case: cassava-based crop combinations. Cassava is dominated in combination with maize while it is the dominating species in combination with low-growing species. Combinations with maize or legumes show a real biological advantage over the...

Autor: Ezumah, H.C.

Five maize genotypes differing in plant habit and growth period were evaluated at 5 population densities (10, 20, 40, 80 and 160 × 103 plants/ha) under an intercropping system with cassava at 1 × 1 or 1 × 0.67 m spacings in a tropical Alfisol in southern Nigeria. The 2-year study revealed signifi...

Cassava (Manihot esculenta Crantz)/Maize (Zea mays L.) intercropping is so popular in Nigeria that a cassava/maize intercropping package is recommended to small-scale farmers. Farmers insist on including low-growing vegetables like okra (Abelmoschus esculentus Moench) and egusi melon (Citrullus l...
