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 ...
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 ...
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 ...
Determining comparative advantage through DRC analysis: guidelines emerging from CIMMYT's experience
Knowledge of comparative advantage is important for developing countries, because potential welfare gains from specialization and trade can be used to foster economic growth. One practical difficulty with using comparative ...
From agronomic data to farmer recommendations
