Although farmer participation is an important concept in farming systems programs, farmer participation is typically restricted to the management of on-farm trials and little information exists on alternative approaches. This paper evaluates three approaches to farmer participation differentiated...

Neglected by research and development, knowledge of the genetic diversity in Ethiopian yams is found mainly with the local farmers. The local yam classification system in Southern Ethiopia was studied through individual and key informant interviews. Data collected include attributes/traits of eac...

The lack of good quality planting material of farmers' cassava varieties, produced locally and at low cost, is a major constraint limiting the expansion of cassava production in Colombia. This article describes the adaptation of conventional cassava propagation to a low-input scheme for rural tis...

Integrated pest management (IPM) has been widely promoted in the developing world, but in many regions its adoption rates have been variable. Experience has shown that to ensure IPM adoption, the complexities of local agro-production systems and context-specific folk knowledge need to be apprecia...


Wyckhuys, Kris A.G.O'Neil, RJ[Local agro-ecological knowledge and its relationship to farmers' pest management decision making in rural Honduras]Local agro-ecological knowledge and its relationship to farmers' pest management decision making in rural Honduras

To guide soil fertility investment programmes in sub-Saharan Africa, better understanding is needed of the relative importance of soil and crop management factors in determining smallholder crop yields and yield variability. Spatial variability in crop yields within farms is strongly influenced b...

In South America, lance flies (Diptera: Lonchaeidae) are key pests of cultivated Passiflora spp. (passionfruit; Violales: Passifloraceae), but little is known about how to control these pests in Passiflora orchards. Here, we relate agro-ecological knowledge and pest management of Colombian Passif...

Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers...

This paper evaluates the utility of the `learning selection' model of the early adoption process, based on a constructivist conceptual framework, to explain farmers' adoption and rejection of two soil-improving technologies alley farming and the use of Mucuna cover crops. The analysis showed th...
