Abstract
The research entitled “A Comparative Effect of Inorganic
Fertilizer (14-14-14) and Organic Fertilizer (combined
SEAWEED and AZOLLA leaves) on the Growth and Yield of Bell
Pepper (Capsicum annum)” aims to find out the effects of
organic and inorganic fertilizer to the growth and yield of
bell pepper. The independent variables are the organic and
inorganic fertilizer while the dependent variable is the
growth and yield of bell pepper based on the time it takes
for the bell pepper plant to grow flowers, the time it
takes for the bell pepper plant to bear vegetables, height
of the bell pepper plant, number of functional leaves, and
number of flowers. The subjects of the study are the 45
bell pepper plants. There will be three treatments the
Organic fertilizer (seaweed and azolla leaves) will be
applied randomly to 15 bell pepper plants and labeled as
set up A, inorganic fertilizer (14-14-14) will be applied
randomly to another 15 bell pepper plants and labeled as
set up B and the remaining 15 bell pepper plants will not
receive any fertilizer at all and labeled as set up C.
After gathering the data it will be subjected to SPSS for
statistical and descriptive analysis. Kruskal-Wallis Test
will be used to determine the significant difference in the
growth of the bell pepper seedlings in terms of their
height and number of photosynthesizing leaves.

Introduction of the Study
Background of the Study
Bell peppers are native to Mexico, Central America,
and South America. Botanists may dispute the bell pepper's
original birthplace, but its amazing journey across the
world and its adoption by almost every culture proves that
the bell pepper is truly a global food. The bell pepper has
been with many cultures for so long - over five hundred
years.
In some cases, most people would be surprised to
discover that it originally came from South America.
Bell peppers are thought to have been eaten in Meso-America
as early as 5000 BCE and to have been growing since 7000
BCE. Archaeologists have estimated that humans began
farming bell peppers between 5000 BCE and 3400 BCE, which
makes them one of the oldest crops cultivated by man.
Clearly, bell peppers had been around long before
Christopher Columbus discovered their heat on his travels
to America. In fact, confusing the bell pepper with the
pepper he was hoping to find in India, Columbus named it
pimiento, or, Spanish for pepper. Bell pepper, however, has
no relation to the black pepper, known as Piper nigrum, for
which Columbus was searching. Columbus later brought the
bell pepper back to Spain; calling it a spice even though
it is a member of the Solanacenae family, impede the bell
pepper's almost immediate migration across the world.
Varieties of bell pepper are based on the color
which can be green, red, yellow, orange and more rarely,
white, purple, blue, pink, rainbow, aqua, violet, maroon,
black and brown, depending on when they are harvested and
the specific cultivars. Green peppers are less sweet and
slightly bitterer than red, yellow, or orange peppers. The
taste of ripe peppers can also vary with growing conditions
and post-harvest storage treatment; the sweetest are fruit
allowed to ripen fully on the plant in full sunshine, while
fruit harvested green and after ripened storage are less
sweet.
The bell pepper's global presence owes much to its
resilience and capacity to be spread even without human
intervention. The flesh of the bell pepper dries well and
the seeds survive for long periods, which allowed the bell
pepper’s easy transport on its first trans-Atlantic trip.
Furthermore, the chili's small size proved tempting to
birds that eat the fruit and deposit the seeds miles away.
Bell peppers are sold in both its immature green state
and its red, yellow, or orange ripe state. They may be
eaten cooked or raw, such as in salads. They also may be
ground in to a powder and added to fruit as a coloring or
flavoring.
Bell peppers offer a number of nutritional values.
They are excellent sources of Vitamin C and Vitamin A and
bell pepper contains phytochemicals (GMF 2008). They also
are a source of vitamin B6, folic acid, beta-carotene, and
fiber. Red peppers also contain lycopene, believed
important for reducing risk of certain cancers (prostrate
cancer, cancer of the cervix, bladder and pancreas) (GMF,
2008). Various studies on red peppers or their components
support the view that bell peppers have a productive effect
against cataracts, rheumatoid arthritis, and lung cancer
(GMF 2008).
According to Dr. Lynette Morgan, a soil-grown bell
pepper crop, the amount, type, and combination of
fertilizer that is required is dependent on the fertility
of the soil used. Different soil types have very different
natural fertility levels and will be affected by any
fertilizer that may have been previously applied. The pH of
the soil also needs to be considered. As a very general
guide, a combination of one part each of the 14-14-14 will
provide a reasonable N-P-K level for a pepper crop.
However, the levels of calcium, magnesium, and trace
elements in the soil should also be checked in case they
need boosting.
A close look at some of the fresh water ecosystems and
trained eye can observe a few green colored ferns freely
floating on the water surface. These ferns are known as
Azolla the nature’s gift to mankind in harvesting
atmospheric nitrogen from the air and good for growing bell
peppers combined with seaweed.

Statement of the Problem
This study aims to determine the effect of different
concentration of inorganic fertilizer (14-14-14) and
organic fertilizer (combined seaweed and azolla leaves) on
the growth and of bell peppers.
Specifically this study seeks to answer the following
questions:
1. What are the effects of the organic fertilizer
(combined seaweed and azolla leaves) to the growth
of the bell pepper plants in terms of the following:
A. number of leaves that is green in color, and
capable of photosynthesizing.
B. measurement of the plant from the soil to last e
exposed node of the leaf in centimeters.
C. number of functioning branches, and green in color.
D. number of fruits 3-4 inches in length.
E. Yield-
a. Marketable- fruits of the bell pepper plant is
healthy, no parasites and green in color.
b. Non-marketable- fruits of the bell pepper plant
is wilt, have parasites and yellowish in color.
2. Is there a significant difference in the growth of
bell pepper plant applied with organic fertilizer
(combined seaweed and azolla leaves) and inorganic
fertilizer(14-14-14)?
Hypothesis
Based on the presented problems, the hypothesis is
formulated.
1. There is no significant difference in the growth of
bell pepper plant using the organic and inorganic
fertilizers.
Significance of the Study
The success of the study will be beneficial to the
following:
School, TLE teachers particularly agriculture teachers.
Department of Agriculture, this study could help them
determine the right soil and concentration in producing the
best and one of a kind bell pepper. In this way, they could
have a seminar and workshops regarding the proper way of
planting bell pepper for less cost and greater yield. In
addition to that, many of the Philippine growers nowadays
are practicing the organic way of farming so that Filipinos
could avoid some unhealthy features of plants, which were
brought up by inorganic fertilizers.
For the bell pepper growers, learning new techniques
and knowledge regarding bell peppers are of great help to
them. This study shows efficient and effective ways on how
to produce best quality of bell peppers in an effortless
way. And there is no need for the growers to apply much
fertilizer and other pesticides.
For the people in the community, this study will help
them in choosing and preparing the proper soil medium in
growing not only bell pepper but also other fruit and
vegetable bearing plants that they could grow in their
backyard. This could help them save money and could assure
them that what they produce is healthy and are not
dangerous to human health.
In some Farm Schools, this would serve as their
reference on the selection of soil medium, manner of
planting and caring of vegetable bearing plants especially
bell pepper.
Furthermore our study would be beneficial to the
future researchers on the same field for this will serve as
their guide as they go along with their study.

Review of Related Literature
Bell Pepper
Bell pepper (Capsicum annum) Solonaceae, is a
vegetable of widespread popularity in Mexico. From its
native home it has been introduced into several tropical
countries including Philippines. The colorful varieties of
these vegetables are now beginning to appear in our
vegetable markets and indications are that bell pepper can
be grown here into a major vegetable crop.
Uses and Nutrition
Bell peppers are sold in both its immature green state
and its red, yellow, or orange ripe state. They may be
eaten cooked or raw, such as in salads. They also may be
ground in to a powder and added to fruit as a coloring or
flavoring.
Bell peppers offer a number of nutritional values.
They are excellent sources of Vitamin C and Vitamin A (GMF
2008). They also are a source of vitamin B6, folic acid,
beta-carotene, and fiber. Red peppers also contain
lycopene, believed important for reducing risk of certain
cancers (prostrate cancer, cancer of the cervix, bladder
and pancreas) (GMF, 2008). Various studies on red peppers
or their components support the view that bell peppers have
a productive effect against cataracts, rheumatoid
arthritis, and lung cancer (GMF 2008).
Propagation
Peppers are best started from seeds indoors in late
winter and then transplanted into the garden after the soil
and air have warmed in the spring. The plants cannot
tolerate frost and do not grow well in cold, wet soil. When
night temperatures are below 50º to 55ºF, the plants grow
slowly, the leaves may turn yellow and the flowers drop
off. Raised beds, black plastic mulch and floating row
covers may be used to advantage with peppers to warm and
drain the soil and enhance the microenvironment of the
young pepper plants in the spring, when cool weather may
persist.
Inorganic Fertilizer (14-14-14)
The numbers refer to the percent by weight of the
following elements (in order(; N,P,K. The elements are in a
salt form, so the weight does not add up to 100%.
The three numbers shown on fertilizer containers are
the fertilizer analysis. They indicate the percent of
nitrogen, phosphorus and potassium present in the
fertilizer. These figures are always listed in the same
order. So, a 100-pound sack of 10-20-10 fertilizer contains
ten pounds of phosphorus and 10 pounds of potassium. That
equals 40 pounds of nutrients. The rest of the fertilizer
is simply carries or tiller, such as sand, perlite or rice
hulls. A complete fertilizer is one with all three
elements. A general recommendation for gardens and flower
beds is 2-3 pounds of a slow release, compete fertilizer
such as 19-5-9 per 100 square (10’x 10’) feet of planting
area.
Organic Fertilizer
(Combined Azolla and Seaweed)
Seaweed
Seaweed is a loose colloquial term encompassing
macroscopic, multicellular, benthic marine algae. The term
includes some members of the red brown, and green algae.
Seaweeds can also be classified by use ( as food, medicine,
fertilizer, industrial, etc.).
Seaweed Agricultural Uses
As we have mentioned, seaweeds have been used in the
Agricultural industry for centuries now, though only
seaweeds from the brown and red zones are commercially
harvested. The earliest traces of life on earth, about 3.5
billion years old, include forms of blue green algae
equipped with chlorophyll. Many tests have been performed
on these enormous plants other than themselves. Kelpak for
instance, which is a new liquid seaweed concentrate, is
made from brown kelp and harvested near South Africa’s
western coast. It is liquefied without heat, chemicals,
freezing, or dehydration. In some of these tests performed,
a dilute solution was applied to plants as a soil soak or
leaf spray. The growth of these plants was tremendous. The
plants which were doused with seaweed had an improved root
growth and yield which had increased by up to 40 and 60
percent. It had accelerated marigold flowering, and also
increased the size and chlorophyll content of the swiss
chard. All of these effects primarily were attributed
natural growth promoters in the seaweed. The rich
agricultural crops typical of Northwestern France are
attributed directly to regular use of seaweed fertilizer.
The seaweed industry itself is relatively valuable because
it can be used as fertilizers or even as substitute for
soil. This seaweed has been used by the agricultural
industry in animal fodder and in fertilizers that improve
the nutrient content as well as the mechanical properties
of the soil (Libyan and Wayne, 1981). This in turn has had
a tremendous result on the plants and animals that directly
consume this seaweed. Growth, health, and quality have all
been a result of this added fertilizer.
Azolla
“Agriculturally, Azolla is famous for its symbiosis
with the nitrogen-fixing Anabaena azolle Strasburger, a
cyanobacterium (blue-green algae) found at the stem apices,
and in cavities of the upper leaf lobes. Because the plants
fix nitrogen, they are often used as green fertilizers or
mixed with livestock feed as a nutritional supplement.
Azolla pinnata has been cultivated for many centuries in
rice paddies of Northern Vietnam and southern China, where
it acts as a fertilizer after it decomposes.
Azolla is the most frequently studied genus of
miniature ferns in the world because of its economic
importance. The three North American species are
naturalized in Europe and South Africa, and they have been
introduced into Hawaii for horticulture into Asia for
agriculture. All species have been studied for agricultural
uses in rice-producing areas.
Azolla is usually found in stagnant or slow-moving
water ponds, lakes, marshes, swamps, and streams. Plants
turn reddish when under stress, poor nutrition, high
temperatures. Sporulation needs further investigation.”

Research Design and Methodology
Purpose of the Study and Research Design
The main purpose of the study is to determine the
effectiveness of the organic fertilizer (combined azolla
leaves and seaweed) to the growth of the bell pepper plant.
The experimental research design will be used in this study
for it is the most suitable process for obtaining the
needed data.
The dependent variable involved in the study is the
growth of the bell pepper plant and the independent
variables are Inorganic Fertilizer (14-14-14) and Organic
Fertilizer (Combined Seaweed and Azolla Leaves)
Methods
Subjects
The subjects of this investigation are the 45 bell
pepper plants. There will be three treatments the Organic
fertilizer (seaweed and azolla leaves) will be applied
randomly to 15 bell pepper plants and labeled as set up A,
inorganic fertilizer (14-14-14) will be applied randomly to
another 15 bell pepper plants and labeled as set up B and
the remaining 15 bell pepper plants will not receive any
fertilizer at all and labeled as set up C.
Materials
1. Seaweed and azolla leaves
2. Bell pepper seeds
3.14-14-14 fertilizer
4. plastic bags
5. trowels
6. weighing scale
7. meter stick
Procedure
A. Gathering of Materials/Samples
The researchers will plant the bell pepper seeds
in the black plastic bags needed in the experiment.
Forty-five (45) bell pepper seeds will be used. Each 15
bell pepper seeds will be randomly applied by organic
fertilizer, another 15 bell pepper plant will be applied
by inorganic fertilizer and the remaining 15 bell pepper
plant will be the control group.
B. Planting
The bell pepper seeds will be planted one in
each plastic bag prepared.
Using a trowel, a hole will be made at the center
about three (3) inches deep. Then, the bell pepper
seedlings will be inserted in it and the soil around the
seedlings will be tightly packed. When the tiny pepper
plants are strong enough, they are transplanted to the
field and planted in rows 3-4 feet apart. The plants are
grown like tomatoes, but stakes are not used because
pepper plants only grow 3-4 feet high.
Green bell varieties are usually picked when they
are fully grown and mature – 3 to 4 inches long, firm and
green. When the fruits are mature, they break easily from
the plant. Less damage is done to the plants, however, if
the fruits are cut rather than pulled off. The new,
colored bell pepper fruits may be left on the plant to
develop full flavor and ripen fully to red, yellow,
orange or brown; or they may be harvested green and
immature. Some (including “white”, light yellow, lilac
and purple) are colors that develop in the immature fruit
and that should be harvested before actually ripening,
when they turn red.
C. Watering and Application of Fertilizer
Water will be administered as needed, three (3)
times a week or as necessary.
Organic fertilizer (seaweed and azolla leaves)
will be applied randomly to 15 bell pepper plants and
labelled, inorganic fertilizer (14-14-14) will be applied
randomly to another 15 bell pepper plants and the
remaining 15 bell pepper plants will not receive any
fertilizer at all.
Pesticide will be sprayed on the seedlings as
needed.
Data Analyses and Procedure
The data obtained in this investigation will be
subjected to the following descriptive and inferential
statistics.
Mean –
Kruskal-Wallis Test – will be used to determine
the significant difference in the growth of the bell
pepper seedlings in terms of their height and number of
functional leaves.
Data to be collected in Kruskal-Wallis Test:
1. Number of leaves- number of leaves that are green
in color, and capable of photosynthesizing.
2. Height- measurement of the plant from the soil to
last exposed node of the leaf in centimeters.
3. Number of branches- number of functioning branches,
and green in color.
4. Number of fruits- number of fruits 3-4 inches in
length.
5. Yield-
A. marketable- fruits of the bell pepper plant is
healthy, no parasites and green in color.
B. Non-marketable- fruits of the bell pepper
plant is wilt, have parasites and yellowish in
color.
