The Role of Agricultural Extension Programs On Crop Farming Technical Efficiency

Abstract

Extension services have become the gold standard for agricultural development programs to spur farm productivity and enhance farmers’ livelihood. Scholars from distinct strands of research have contested the virtues of these programs as systematic reviews failed to disentangle the different causal paths. We aim to unpack the relationship between these two constructs, and more specifically explore the main determinants causing systematic variabilities of the technical efficiency estimates from well-known published crop-farming studies. A meta-regression analysis is implemented by collating 335 observations from 199 farm-level studies to review the direct impact of agricultural extension activities on farming performance. While the implementation of expansion programs tends to be non-randomly distributed in our sample, we employ the inverse probability of treatment weighting to correct for potential selection bias. The absence of a publication bias in found studies our meta-analysis is empirically identified. Our empirical findings are robust when multiple imputation method is employed to mitigate the missingness of observations. Consonant with the theory of agricultural extension, we find that extension significantly improves technical efficiency by 4.8% to 7.6%. Farm productivity significantly differs in country level characteristics, type of crops and model specification.JEL Classification: Q16, O18, C14, C29

The Impact of Agricultural Extension Services on Farm Output: A Worldwide Viewpoint

“…As farmers embrace more productive and efficient agricultural techniques, there may be an increase in production as a result of this knowledge transfer [17,53] . Demonstration farms are often created to demonstrate best practices in several facets of agriculture, including crop selection, soil management, pest control, irrigation techniques, and more [1,37] .…”

“…Agricultural extension may be used to improve customers' decision-making, management, and problem-solving abilities. This method of getting specialised knowledge from public policy or research down to the farm level is frequently employed all around the world [1] . According to Bitzer [2] , the majority of industrialised countries have established a system of consulting services for owners and managers of rural property, which is mostly funded by general taxes and offered by public institutions.…”

Willingness of Tea Farmers to Adopt Ecological Agriculture Techniques Based on the UTAUT Extended Model

“…Misunderstandings may therefore lead to improper applications of the technology, which would be counterproductive. The involvement of scientific and technical personnel at grassroots level, as well as regular training courses [13,47] to help tea farmers correctly grasp the applications of new technology, would be conducive to continuous use and word-of-mouth promotion of technology.…”
