Abstract
This study examined the effects of ICT infrastructure adoption on agricultural output in Nigeria. Annual data on fixed
telephone subscriptions, mobile phone subscriptions, internet usage, ICT goods import and some production variables spanning
from 1994 to 2023 were used for the study. The unit root test of stationarity of each variable was obtained using the Augmented
Dickey–Fuller (ADF) while the existence of long-run and short-run relationship among the variables was established using Engle
and Granger 2-step approach. The ADF results revealed that all variables were integrated order of one I(1) and the error term
of the long-run regression was stationary at level . Then, we implemented error correction model (ECM) to examine the short
run relationship between agricultural output and the ICT variables under consideration. The overall estimated result showed a
significant long-run relationship between agricultural output and mobile phone subscriptions (=0.027), internet usage (=2.593),
ICT goods import (=2.357), and short-run significant relationship with only ICT goods import (ϕ=0.996) and mobile phone
subscriptions (ϕ=0.160). Fixed telephone did not have significant influence on agricultural output both in the short-term and
long-term. The study suggests implementation of policies that will improve the existing level of ICT facilities for enhancement
of more agricultural output.
