It is concluded that foliar application of chitosan at vegetative
stage enhanced the plant growth and development, which
resulted from increased fruit yield in okra. Among the
concentrations, 100 and 125 ppm had superiority for plant
growth, yield components and fruit yield over 50 and 75
ppm. Therefore, application of chitosan at the rate of 100 or
125 ppm may be recommended for okra cultivation.
However, more experiments should be conducted in different
locations and seasons to draw a valid conclusion regarding
the chitosan foliar application for fruit yield improvement of
okra.
