Maize technology in Malawi: a green revolution in the making?
(CIMMYT, 1995)
This case study of technical change in maize production in Malawi seeks to answer the question of whether the diffusion of improved maize seed and fertilizer among Malawian smallholder farmers will create the sharp yield ...
Book
Wheat harvest technology in Punjab's rice wheat zone: combines, laborers and the cost of harvest delay
(PARC; CIMMYT, 1987)
Combine-users in Punjab's rice-wheat zone tend to be large owner operators who harvest a total of over 20 hectares in either wheat or rice. Although a slightly higher proportion combine rice, those who combine wheat ...
Book
Optimal search in ex situ collections of wheat genetic resources
(CIMMYT, 1998)
This paper develops a theoretical model for analyzing gene bank management decisions regarding the search for traits of economic value in ex situ collections of wheat. The model is applied to data on the probability of ...
Book
The economic impact in developing countries of leaf rust resistance breeding in CIMMYT-related spring bread wheat
(CIMMYT, 2004)
This study was undertaken to estimate the economic impact of efforts since 1973 by the International Maize and Wheat Improvement Center (CIMMYT) to develop spring bread wheat varieties resistant to leaf rust caused by ...
Book
Using economics to explain spatial diversity in a wheat crop: examples from Australia and China
(CIMMYT, 1999)
Spatial diversity indicators may serve an important function for policymakers as they seek to manage crop genetic diversity and potential externalities associated with diffusion of some types of genetically improved crops. ...
Book
A conceptual framework for valuing on-farm genetic resources
(CIMMYT, 1998)
This paper proposes a preliminary conceptual framework designed to support strategic decisions about which crop populations-in a well-defined reference area within a crop's center of diversity-are suitable candidates for ...
Book
Farmer management of maize diversity in the Central Valleys of Oaxaca, Mexico: CIMMYT INIFAP -- 1998 Baseline Socioeconomic Survey
(CIMMYT, 1999)
Descriptive data from the sample survey of households in the study communities enable us to profile the characteristics of: (1) farm households; (2) the maize populations they grow, based on their own descriptors and the ...
Book
The private and public characteristics of maize land races and the area allocation decisions of farmers in a center of crop diversity
(CIMMYT, 1999)
This study uses an approach derived from models of the private and public characteristics of goods to illustrate (1) the overriding importance of variety attributes in farmers' decisions to allocate area among varieties ...
Book
Identifying appropriate germplasm for participatory breeding: an example from the central Valleys of Oaxaca, Mexico
(CIMMYT, 2000)
Identifying the appropriate germplasm to be improved is a key component of any participatory breeding effort because of its implications for impacts on social welfare and genetic diversity. This paper describes a method ...
Book
Sources of productivity growth in wheat: A review of recent performance and medium-to long-term prospects
(CIMMYT, 1999)
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 ...
