An agro-economic evaluation of maize production in three valleys of the Peruvian Andes
In cooperation with researchers in many national agricultural research programs, CIMMYT has sought to develop procedures which help to focus agricultural research squarely on the needs of farmers. The process involves ...
Simple statistics for manual analysis of farm survey data
When conducting fontal surveys for the purpose of helping focus on-farm agronomic experiments, experience indicates that a relatively small sample of farmers is normally sufficient for a given recommendation domain or ...
Continuous versus discrete economic analysis of experimental data
Economists are often called upon to analyse experimental data in order to formulate appropriate recommendations for farmers. The data may be analysed as a set of discrete points or it may be possible to represent the data ...
Report of a seminar for senior agricultural research administrators from Eastern and Southern Africa
Dr. Don Winkelmann welcomed participants to Nairobi and outlined briefly the purpose of the meeting; to exchange views on the potential and present status of On Farm Research with a Farming Systems Perspective (OFR/FSP) ...
Economic analysis of 2 4 factorial agronomic experiments
The 24 factorial experiment has become increasingly popular in on-farm agronomic experimentation, in part due to the efforts of CIMMYT's maize training program. This experiment is used to examine main effects and interactions ...
Deriving optimum fertilizer levels: the naive economist versus the practical farmer
In establishing fertilizer recommendations for farmers, standard production function analysis has been widely applied to the analysis of fertilizer experimental data in order to derive optimal levels of fertilizer. That ...
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 ...
The planning stage of on-farm research: identifying factors for experimentation
(CIAT; CIMMYT, 1989)
On-farm research is a problem-oriented approach to agricultural research that begins by diagnosing the conditions, practices, and problems of particular groups of farmers. Once the problems are identified, a research program ...
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 ...
