Irrigation is essential wherever little or
no rain is available during the growing season. Irrigation is
most critical during the time of flowering and fruit set. A lack
of water during this period could lead to the development of
blossom-end rot and malformed fruit. Reduction of fruit size
and yield are also caused by moisture stress.
Wilting during the late morning is a good indication that the
crop needs irrigation. Eggplant is a medium-rooted crop with
a root zone depth of 90 cm in well-drained soil. Irrigate soil
to at least 45 cm deep.
The method of irrigation depends on soil texture, topography,
and water supply. Generally, furrow (surface) irrigation and
drip irrigation systems are used. In addition, mulching with
black plastic will maintain more uniform soil moisture between
irrigations. |
