Objectives : Atthe end of discussion; students
should be able to:
Identify the factors to consider in site selection;
Select a site appropriate for rice production;
Appreciate the value of selecting a good site for rice production
State the kinds of soils in agriculture
If given achance to select a
good site for rice production
here are the important factors
to consider to ensure optimum
growth and development.
These are Soil, Climate,
Location.
6.
The following arethe different factors to be
considered in selecting a good site for rice
production :
1. Soil – A rice field should possess the
following attributes:
A. High Clay Content
B. Medium Amount Of Organic Matter
C. Good Drainage
D. Top Soil 18-20 Cm Deep
E. Soil Ph Range Of 6.2- 7.0
7.
2.Climate – Climatechange is
one of the factors posing
challenge to rice production
nowadays.
These factors include rainfall,
sunlight, wind velocity, and
temperature.
8.
A. Rainfall
In rainfedareas the start of the rainy
season determines the planting time.
This is because the source of water
supply for non-irrigated rice field comes
directly from the rainfall. One the other
hand too much rainfall. On the other
hand too much rainfall causes floods
that submerged the plants. Water
directly affects the photosynthetic
activity of rice plant.
9.
B. Sunlight
It isthe foremost source of
energy of all plant life. When
water supply is not limited,
sunshine is the most
important climate factor that
influences rice yield.
Therefore, site should free of
any barrier to sunlight.
10.
C. Temperature
It isa limiting factor in
rice production
however in the
Philippines,
temperature is almost
constant hence it is
not a critical problem.
11.
D. Wind velocity
Gentlewind is beneficial to rice
plant because new air blown
around the plant causes
replenishment of carbon dioxide.
Strong wind such as heavy wind
typhoon may cause lodging and
shattering of rice grain, reduction of
photosynthesis activities and may
enchance growth of bacterial leaf
dieases.
12.
3. Location
Farm locationgreatly
affects the profitability
of rice production . The
following are some
factors to consider :
13.
The farm shouldbe near the
road to facilitate ease of
transport.
There should be available
laborers in the different stages
of rice production.
Sandy Soil
Are generallydry,
nutrient-dense, and
fast-draining.
It is used for planting
and cultivation.
21.
Clay Soil
Clay'sheavy and
compact structure
holds moisture well and
is ideal for moisture-
loving plants.
22.
Loamy Soil
Loamy soilis ideal for
most garden plants
because it holds plenty of
moisture but also drains
well so that sufficient air
can reach the roots.
