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. ...
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 ...
Genetic change in farmer-recycled maize seed: a review of the evidence
This paper summarizes what is known about farm-level maize seed management practices and reviews the theoretical and empirical evidence regarding the relationship between farmers’ seed recycling practices and the genetic ...
Sources of productivity growth in wheat: A review of recent performance and medium-to long-term prospects
Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years ...
Maize production practices in Paraguay: survey findings and implications for research
Data collected through a survey of 252 rural households support the conventional wisdom that maize in Paraguay is grown by many different categories of producers, ranging from small-scale semisubsistence farmers to large-scale ...
Comparative advantage and policy incentives for wheat production in rainfed and irrigated areas of Mexico
Increasing demand for wheat products and Mexico's trade and financial situation are placing pressure on expanding domestic wheat production. As expansion in irrigated areas will be limited to yield increases unless wheat ...
The economics of small-scale wheat production technologies for Kenya
Kenya is a net importer of wheat and is projected to remain so to the end of this century. Wheat is grown in Kenya using mechanized production methods that differ little from what might be observed in many industrialized ...
Farmers' practices, production problems and research opportunities in barley production in the Calpulalpan/Apan valley, Mexico
Since 1975, CIMMYT's Wheat Training Program has conducted experiments on improved barley, wheat and triticale technologies in farmers' fields in the high valleys of the States of Mexico, Hidalgo and Tlaxcala, Mexico. These ...
The rate and sequence of adoption of improved cereal technologies: the case of rainfed barley in the Mexican Altiplano
In efforts to understand the process of agricultural develoµtent, economists and other social scientists have invested substantial resources in literally hundreds of studies of the adoption of new agricultural technologies. ...
The economic returns to institutional innovations in national agricultural research: on-farm research in IDIAP Panama
The paper presents a method for analyzing the returns to investment in on-farm research. It then applies the method to a location-specific maize research program in Caisan, Panama. The results show a rapid adoption of the ...
