Q.9L\
\h'creases as wind speed increases.

Some plant species have the

ability to close their stomata as wind velocity increases thus

decreasing potential transpiration.

Climatic data required to specifically assess wind conditions in the

project area are lacking.

Based on project area analyses, including

interviews

with

professional

agriculturalists

and

growers,

prevailing wind conditions have an insignificant impact on crop

production in the project-area.

3.6 SOLAR RADIATION

Sunlight provides energy for the photosynthetic process which makes

plant growth possible.

Light is necessary for the production of

chlorophyl in green plants.

Chlorophyl is the green pigment in

plant cells necessary for photosynthesis. When illuminated by

light of sufficient intensity, chlorophyl produces carbohydrates

from ~arbon dioxide and water.

The photosynthetic rate is dependent on light intensity. Outer

leaves of agronomic crops require as much as thirty percent full

sunlight to become light saturated or to reach the point where

further increase in light intensity does not increase the

photosynthetic rate. While outer plant leaves become light

saturated early in the day, inner leaves which depend on reflective

light may not reach saturation intensity until much later in the day.
