Technical change in maize production: a global perspective
The stages of technological change in maize production in commercial and small-scale semisubsistence systems are discussed and variation in the use of improved varieties/hybrids and adoption of associated inputs are noted. ...
Continuous economic analysis of crop response to fertilizer in on-farm research
This paper proposes a method for building general models based on continuous analysis of data from on-farm research (OFR) in order to derive recommendations for farmers. The data requirements are not excessive for practitioners ...
Institutionalizing the role of the economist in national agricultural research institutes
The evolution of the role of economists in agricultural research institutes (ARIs) over the past two decades is described. A framework for determining relevant research activities for economists in ARIs is presented, with ...
The design and management of call system training in on-farm research
This paper, intended for those engaged in training national research and extension personnel in on-farm research (OFR) methods, summarizes the experiences of the CIMMYT Economics Program, in collaboration with members of ...
Continuous versus discrete economic analysis of experimental data

Data collection, site selection and farmer participation in on-farm experimentation
This paper contains suggestions for improving data collection during on-farm experimentation. Besides providing agronomic data, the experimental phase of on-farm research can be a source of other valuable information. ...

This paper provides a thorough examination of the concept of; the recommendation domain. It outlines the use of the concept in different stages of on-farm research, pro; vides examples of recommendation domains as used in ...
Exercises in the economic analysis of agronomic data
This publication consists of sixteen exercises which are used in teaching the economic analysis of on-farm experimentation CIMMYT trainees. The exercises focus on the construction of partial budgets and the techniques of ...
Demand and supply of crop infraspecific diversity on farms: towards a policy framework for on-farm conservation
Interest is increasing worldwide in on-farm conservation as a component of a strategy to conserve crop genetic resources. On-farm conservation may require outside support to small-scale farmers in areas of crop domestication ...
Understanding global trends in the use of wheat diversity and international flows of wheat genetic resources
This paper discusses the centers of origin and diversity for bread wheat; sketches historical patterns in the sources and use of wheat genetic resources in modern plant breeding; identifies and compares indicators of genetic ...
