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 ...

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 ...

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 ...

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) ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
