An important component assumption that encourage economically sound technically efficient use, not simply increased use. concludes: A likely elicit greater increase aggregate than simple movement along response lower price. Effective for based on farmers' perceptions response, which may differ from observed scientists. Hence, be through agricultural research identifies more responsive crop varieties land husbandry practices efficiency reduce production risk.
