selecting site for corn production

1. LESSON 1
SELECTING THE IDEAL SITE FOR
PLANTING

2.  SOIL – the loose material of the land
surface of the earth in which plants find
a place to grow
 Climate – the atmospheric condition of
the earth surface prevailing for a long
period of time
 Temperature – the degree of hotness or
coldness of the atmosphere at a period
of time
 Humidity – the degree of wetness
especially in the atmosphere

3.  Soil pH – the range of acidity and
alkalinity of the soil
 Corn – an annual plant with a tall
solid stem, fibrous root system and
long narrow leaves borne alternately
on either of the stem scientifically
called Zea mays Linn
 Topography – a description of all the
surface features natural or artificial, of
a particular place

4.  Culms – the stem of the corn
 Soil structure – to the arrangement of
the soil particles
 Soil texture – to the size of the soil
particles
 Moisture retention – the holding
power or ability of the soil to keep
water
 Photo periodism – the length of
exposure to sunlight

5.  CORN – is one of the major crops
grown in the Ilocos region
 - It is primarily food for animal feeds
to support the poultry, swine and
cattle raisers, feed millers, green
corn vendors vendors and cornik
processors.
 -glutinous corn could be harvested
as “green “and as a grain to be
processed as chicharon or cornik.

6. 3 FACTORS TO CONSIDER IN SELECTING
THE SITE FOR PLANTING
Soil– high yield of corn may be obtained with the following soil conditions:
1. Well drained roots develop best in well – drained soil.
2. At least 80 cm deep- a deep soil holds moisture and provides the needed
nutrients for the plant.. Corn grows well in a field that is rolling slightly to flat
/level and fairly deep.
3. Medium textured – a loam to silt loam is most favorable but soil texture from
sandy loam is well suited
4. Corn grows well in pH value of 5.3 to 6.0 but it could be grown with a higher pH
8.0
5. Moisture retentive – is the holding power or ability of the soil to keep water .
6. High in organic matter –
7. High fertility – most Philippine soil require the macro elements Nitrogen,
Phosphorus and potassium for a higher yield of corn.
8. Seasonal moisture conditions – on a given soil, an even seasonal distribution of
rainfall affects corn harvest.
