Schoonhoven, Aart vanPachico, Douglas H.[Rice and beans in Latin America: a summary report on the economic impact of improved varieties]Rice and beans in Latin America: a summary report on the economic impact of improved varieties

The genetic changes occuring in av. productivity, adaptation, and response to environments with different levels of yield for black-colored grain material selected by CIAT during 1976-79 are examined. Data from 124 expt. of the International Bean Yield and Adaptation Nursery (IBYAN) of black bean...


Voysest Voysest, Oswaldo[Comportamiento en ambientes de diversos niveles de productividad de genotipos de frijol negro desarrollados en Colombia]Comportamiento en ambientes de diversos niveles de productividad de genotipos de frijol negro desarrollados en Colombia

The effect of irrigating by gravitation on yields of bean var. ICA-Palmar, applied during different growth stages,was studied. A randomized block design was used with 7 replications and 7 treatments in an area of 1.5 ha with furrows at 0.60 m (240,000 plants/ha). The system of irrigating by gravi...

Gepts, Paul L.[Introduccion a las hibridaciones interespecificas con el frijol comun, Phaseolus vulgaris L]Introduccion a las hibridaciones interespecificas con el frijol comun, Phaseolus vulgaris L

The agronomic factors that should be taken into account in the management of bean yield trials are described. These include: determination of the exptl. site (plot background and soil and climatic conditions); mechanized soil preparation; materials required for field trials; fertilization (types ...


Thung, MErazo, OOrtega, J.[Factores agronomicos en el manejo de ensayos de rendimiento en frijol]Factores agronomicos en el manejo de ensayos de rendimiento en frijol
Autor: Mulder, M

An attempt was made to highlight the typical issues concerning vegetables in urban marketing and consumption. A theoretical comparison of vegetables and staple foods was carried out. Then, the typical issues were transposed into hypotheses, which were subsequently investigated. An important issue...


Mulder, M[The differences between urban marketing and consumption of vegetables versus staple foods. A case study on snap bean consumption and marketing in Bogota, Colombia]The differences between urban marketing and consumption of vegetables versus staple foods. A case study on snap bean consumption and marketing in Bogota, Colombia

The purpose of the Bean Web Blight International Nursery (VIM) is to evaluate the degree of resistance or tolerance to Thanatephorus cucumeris of bean var. or advanced lines, and select genes to be incorporated to commercial var. in the different countries where the disease is a constraint to pro...


International Center for Tropical Agriculture[Vivero Internacional de Mustia Hilachosa del Frijol (VIM): Resultados 1973-1985]Vivero Internacional de Mustia Hilachosa del Frijol (VIM): Resultados 1973-1985

The symptomatology and control of the principal bean diseases in Colombia are discussed, classifying them as (1) biotic: root rot caused by fungi, bacteria and nematodes; foliage diseases - anthracnose, rust, angular leaf spot, powdery mildew, Ascochyta leaf spot, gray spot, floury leaf spot, pod...


Castaño, J.J.[Enfermedades del frijol (Phaseolus vulgaris L)]Enfermedades del frijol (Phaseolus vulgaris L)

In hot, humid areas some 40 percent of stored grain in lost; however, control of RH generally requires expensive equipment. The objectives of this expt were to evaluate the behavior of bean seeds of different size, color and moisture content at different levels of RH and to correlate adsorption a...


Álvarez S, E.[Estudio del equilibrio higroscopico de Phaseolus vulgaris L. en relacion a diferentes niveles de humedad]Estudio del equilibrio higroscopico de Phaseolus vulgaris L. en relacion a diferentes niveles de humedad

CIAT has conducted research to develop a method for selecting drought-tolerant genotypes. Bean var. were planted during the dry season. Irrigation was suspended at the initiation of flowering in the dry treatment and the control treatment continued to be irrigated to avoid water shortage. During ...
