Drawing on results of a survey of Ugandan farmers who previously hosted bean (Phaseolus vulgaris L.) varietal trials, this paper reports on the adoption of three new bush bean cultivars and assesses the usefulness of post-trial surveys as a methodology for obtaining reliable early feedback on var...

In the mountainous regions of northern Laos, shifting cultivation, or slash-and-burn agriculture, is widely practiced. However, the crop–fallow rotation cycle is becoming shorter owing to forest conservation policies and population pressure, causing loss of productivity that deleteriously affects...

Bean ( Phaseolus vulgaris check for this species in other resources L.) production in Africa is constrained by edaphic stresses. A pan-African effort, Bean Improvement for Low Fertility in Africa (BILFA), was initiated in 1990 to screen beans for tolerance to several edaphic stresses. In the fir...

Se evaluaron el uso de recursos y la sostenibilidad de tres sistemas agroforestales (bosque secundario-
BS, tala y quema-TQ y sistema conservacionista Quesungual-SAQ). Se utilizaron datos de 15 parcelas
de 200 m² ubicadas entre 14º 05 N y 88º 30 W y transformicidades reportadas en otros estud...

At the Colombian coffee growing area, between 1,000 and 2,000m elevation, experiments were carried out under field conditions on steep slopes at Romelia (2,500 mm rainfall and a Dystrandept type of soil), and at Supía (1,708 mm rainfall and a Eutrandept type of soil). The legumes (Centrosema macr...
