Abstract
To investigate how to motivate public workers and promote the agricultural extension services, this study investigates the impacts of technical training and motivational programs for extension officers on their performance and the adoption of technology by small-scale rice-growing farmers in Tanzania. We conducted a randomized controlled trial by providing training programs on rice cultivation technologies and a program for enhancing intrinsic motivation to randomly selected extension officers. We estimate the Intention-to-Treat effects (ITT) for the impact of agricultural training and motivation programs on the performance of extension workers and farmers’ technology adoption.

Interventions

Intervention(s)
This study investigates the impacts of agricultural training and motivational programs on the performance of extension officers, taking the case of rice farming technologies in Tanzania. For this purpose, we conducted a randomized control trial. We randomly selected 60 extension officers and divided them into three groups: control group (C) who receive no interventions (20 officers); first treatment group (T1) who receive agricultural training on basic rice cultivation technologies (20 officers); second treatment group (T2) who receive agricultural training and motivation program (20 officers). We also conducted interviews with 600 rice-growing farmers overseen by these extension officers.

Primary Outcomes

Primary Outcomes (end points)
Extension experiences, technology adoption, and paddy yield of farmers
Primary Outcomes (explanation)
whether farmers receive any extension services, number of technologies adopted, dummy variable that takes one if a farmer adopt specific technology, paddy yield.

Secondary Outcomes

Secondary Outcomes (end points)
Motivation and performance of extension workers
Secondary Outcomes (explanation)
Number of farmers who received extension services, intrinsic motivation measured by Work-related Basic Needs Satisfaction Scale

Experimental Design

Experimental Design
We conduct a randomized control trial. We randomly select 60 extension officers and will divide them into three groups: control group (C) who receive no interventions (20 officers); first treatment group (T1) who receive agricultural training on basic rice cultivation technologies (20 officers); second treatment group (T2) who receive agricultural training and motivation program (20 officers). We also conducted interviews with 600 rice-growing farmers overseen by these extension officers. We measure the peformance of extension officers by the farmers extension experience, technology adoption, and productivity of rice cultivation. We estimate Intention-to-Treat (ITT) effects.
