Abstract: This article analyses the technical eiciency of maize production in
Zimbabwe’s smallholder farming communities following the fast-track land reform
of the year 2000 with a view of highlighting key entry points for policy. Using a
randomly selected sample of 522 smallholder maize producers, a stochastic frontier
production model was applied, using a linearised Cobb–Douglas production function
to determine the production elasticity coeicients of inputs, technical eiciency and
the determinants of eiciency. The study inds that maize output responds positively
to increases in inorganic fertilisers, seed quantity, the use of labour and the area
planted. The technical eiciency analysis suggests that about 90% of farmers in
the sample are between 60 and 75% eicient, with an average eiciency in the
sample of 65%. The signiicant determinants of technical eiciency were the gender
of the household head, household size, frequency of extension visits, farm size and
the farming region. The results imply that the average eiciency of maize produc-
tion could be improved by 35% through better use of existing resources and tech-
nology. The results highlight the need for government and private sector assistance

ABOUT THE AUTHOR
Nelson Mango is a rural development sociologist
specialised in agrarian transformation processes,
with an emphasis on small-scale farming,
technology development and social change,
endogenous development and rural livelihoods.
Over the years, he has done substantive ieldwork
on socio-technical dimensions of maize, zero
grazing dairy farming, and soil fertility (re)
production in East Africa. He has also worked
on livestock, livelihoods and poverty in southern
Asia and sub-Saharan Africa using a wide range
of methodologies drawn from both quantitative
and qualitative research approaches. In the
southern Africa region, his research focused on
Conservation Agriculture and how to improve
farmers’ livelihoods through multi-stakeholder
innovation platforms and linking them to
extension and business development services.
Currently his research work has shifted to East
and Central Africa with focus on value chains
for nutrition and health, and Policy, Institutions
and Markets. Theoretically, he combines actor
perspective with broader questions related to
political economy.
PUBLIC INTEREST STATEMENT
This article concerns technical eiciency of crop
production as an important aspect of pursuing
output growth in agriculture in developing
countries. Following the fast-track land reform
of 2000, Zimbabwe’s smallholder farming
communities have grown signiicantly and now
produce the bulk of the country’s maize. However,
the sector’s productivity remains low, with yield
per hectare averaging only about 0.7 tonnes,
seemingly because of technical ineiciencies.
This paper contributes to the current debate
in inding ways of raising maize productivity in
smallholder farming by highlighting key entry
points for policy. Findings show that maize output
responds positively to increases in inorganic
fertilisers, seed quantity, the use of labour and
the area planted. This implies that the average
eiciency of maize production could be improved
through government and private sector assistance
in promoting access to productive resources and
ensuring better and more reliable agricultural
extension services.
