Description The projected demand of maize production in India in
2050 is 4–5 times of current production. With the
scope for area expansion being limited, there is need
for enhancement of yield. This calls for identifying
areas where huge unrealized yield potential exists.
With a view to address the issue, the present study
delineates homogeneous agro-climatic zones for maize
production system in India taking district as a unit
and using the factors production, viz. climate, soil,
season and irrigated area under the crop. There are
146 districts in India that grow maize as a major crop.
They were divided into 26 zones using multivariate
cluster analysis. Study of variation in yield between
districts within a zone vis-à-vis crop management
practices adopted in those districts was found useful
in targeting the yield gaps. These findings can have
direct relevance to the maize farmers and district level
administrators.
