CHAPTER I THE PROBLEM AND ITS SETTING
Introduction In the Philippines, agriculture plays a vital role in the economy. There are many provinces in the country and agriculture
is
their
primary
source
of
income.
And
to
improve quality yield of vegetables, fruits and other root crops, many farmers are using different kinds of fertilizer. Agriculture production

potential.
To
maintain
soil
fertility and productivity and to prevent land degradation and erosion, nutrients taken by crops must be replenished through the application of fertilizers. There are several ways to maintain the productivity of agriculture.
The use
of fertilizers, inorganic and organic alike, play a major role in the production of agriculture worldwide (Chand et al., 2006).

fertilizer
decreases
the
danger
of
over-
fertilization because the nutrients are released slowly. The slow release of these nutrients also means they will be available over a longer period of time and less application will be required. Organic fertilizer improves your soil. It does this by escalating the soils ability to hold water and nutrients. It decreases erosion and soil crusting caused by rain
and
wind.
Using

Organic
fertilizer is rapidly growing in favor, because it provides and recycles supplemental nutrients to crops and its nonchemical components greatly reduces waste products (Luo et al., 2006). Livestock manure is a key fertilizer in organic and sustainable soil management. Manure provides plant nutrients and can be an excellent soil conditioner. Properly managed manure applications recycle nutrients to crops, improve soil quality, and protect water quality. It is most effectively used

provided. However, the use of inorganic fertilizer on crops over a period of several years may cause long-term damage to the agriculture and the surrounding economy (Chand et al., 2006). 3
Inorganic fertilizers have the necessary amounts of the three main nutrients that your plants require to help them to survive and flourish. They also release quickly so that your plants are able to get the nutrients they need as soon as possible. If there is an emergency and you need to get your plant fertilized as soon as possible, inorganic will be the right choice for you. The incorrect fertilizer on plants like bitter melon could lead to failure of germination, or might not increase growth in the plants.
Bitter melon, which is known in the Philippines as ampalaya,
is
an
annual
plant
that
is
native
in
this
country. It is botanically known as Momordica charantia L. It can be grown anytime of the year for its edible shoots and fruits and offers a good supply of vitamins and minerals. It is profitable when grown in small or large scale either in lowland or upland rice-based areas. Bitter gourd grows in well drained soil. However, the best soil texture for the crop is either sandy loam or clay loam with pH ranging from of 6.0-6.7. Although the crop can be grown throughout the year, the most profitable growing seasons are from October to December and from May to July because most of the areas are being planted to rice during these periods. Only the “tumana” or 4
the fertile hilly-upland areas are being planted with bitter gourd, hence, production is limited. Plant the crop once every two years in the same area. Since bitter gourd is a heavy consumer of nutrients, the soil is depleted on the second year and thus needs soil amendments. Farmers have a lot of expense due to the application of inorganic fertilizer to their crops. They were used to apply inorganic fertilizer even if it incurred a lot of expense and decrease their income because they are lack of time and knowledge

strategies will be used to harvest and earn more profit from the crops.
Conceptual Framework Growing
root
crops
using
organic
and
inorganic
fertilizer has different advantages and disadvantages. But the main objective of using these fertilizers is to produce 5
more crops and to help farmers to have more profit. (Mendoza et. al., 2009) The
focus
of
this
study
was
conducted
to
compare
organic fertilizer from inorganic fertilizer in terms of its effectiveness. The effectiveness of the fertilizers may be identified through the color and length of the leaves and stems.
Theoretical Framework The theoretical framework of this study is consisted of two subjects namely, organic and inorganic fertilizer.
6
The
only
difference
between
organic
and
inorganic
fertilizer is that organic fertilizers are usually made from natural
materials
such
as
compost,
manure,
or
something
similar, while inorganic fertilizers are either mined from the ground or manufactured. Plants need the same basic elements for growth whether they are provided by an organic or inorganic source. Every farmer or gardener must decide for themselves which method they wish to use, but it is usually best to make one's decision based on sound science, which exists for both types of
fertilizer.
Organic fertilizer is only a source of nitrogen; chemical manmade
fertilizers
can
offer
nitrogen,
potassium,
phosphorous and other microelements. These fertilizers are stable and can be easily transported at long distances (Kent Wagoner, 2010).
Research Paradigm The research paradigm of the study is illustrated in Figure 1. It is contained process leading to answer the 7
problems of the study, namely: (1) Effectiveness of organic fertilizer;

Definition of Terms To ensure a better understanding of the study, the following terms will be defined conceptually:
11
Colour The colour is the appearance of something that has a result

(Webster
dictionary). The term is used to describe the appearance of the leaves in the study. Crops These are the plants that are grown in large quantities for food. The term is used as the main subject of the study. Farmer He is a person who owns or manages a farm. The term is used as the one who plants the crop. Fertilizer It is a substance such as animal waste or a chemical mixture that you spread on the ground in order to make plants grow more successfully. Inorganic fertilizer Is

Length Is the amount that is measures from one end to the other along the longest side. The term is used to identify the measure of the plant’s height.
Livestock Are the animals such as cattle and sheep which are kept on a farm. This term is used to get its manure for the fertilization of the plant. Manure Is animal faeces, sometimes mixed with chemicals, that is spread on the ground in order to makes plant grow healthy and strong. This term is used as the organic fertilizer for the plant.

Association.
Eventually,
these

disappear in soils dependent on inorganic fertilizers. One
of
the
main
differences
between
organic
and
inorganic fertilizers is the timing and rate of nutrient release. Unlike inorganic fertilizers, nutrients in organic fertilizers are often not immediately available to plants
16
after application. The organic forms of nutrients must be converted by soil microbes into inorganic forms before the plants can use them (Gaskell and Smith, 2007). Among all the nutrients
required
for
plant
growth
and
development,
nitrogen (N) is often the most limiting factor. When organic fertilizer is added to a substrate, the organic N sources in organic

of
mineral N to the plants; however, it is a highly variable process that is affected by many factors such as substrate temperature and moisture, microbial activity, and the nature of the organic matter (Kraus et al., 2000;Scagel, 2005). For example, Hartz and Johnstone (2006) found in an incubation study that only 21% (at 15 °C) to 36% (at 25 °C) of the organic N in a pelleted broiler litter product they tested was mineralized in the first 8 weeks after application, whereas

Two

both fertilizers were applied all at once with no further applications of fertilizers for that year.
On the second
year, BM treatments were applied only once and AN treatments were

applications.
Along with the fertilizers, water was also applied to the 18
lima beans by the use of an overhead sprinkler.
After the
2-year period, the crops were harvested and lima bean yield was determined.
Results from the study showed variance in
leaf nutrient concentrations, but fresh pod yields were an equal amount or higher with BM treatment than AN treatment (Luo et al., 2006).
These results were similar to those
from previous studies with the same fertilizers on sweet corn, cabbage, and forages, which are crops grown to feed livestock. Due to the low yield production of agriculture with the use

the
application
of
organic
fertilizers with little or no fossil fuel-based inorganic fertilizers is rapidly gaining favor (Anwar et al., 2005). In 2005, Anwar et al. studied the effect of a combination of organic manures and inorganic fertilizers on the growth and quality

Experimental method or design is future oriented and never hypothesis free. It is the only method of research that can truly test hypothesis concerning cause and effect relationships (Gay, 1976). Ary, et al. (1972) add that experimental method is generally
regarded
as
the
most
sophisticated
method
for
testing hypotheses. The researchers considered experimental method as the appropriate
method
in
the
study
because
the

All
other
variables
except
the
dependent variable are held constant. The effect of the manipulation of the independent variable on the dependent variable is observed or measured. The researchers also considered descriptive method of research
as
an
appropriate
method
in
the
gathering
and
presentation of information in the chosen field of study because the method enables the researcher to interpret the theoretical meaning for further studies.
Methods and Materials
Decomposition of fertilizer Combine one half sack of each carabao and hog manure. Expose the mixture to the sun until it slightly dries. After the mixture has been dried, return it to the sack and mix a small amount of soil about one-fourth sack until the mixture

harrowing, construct trellis at a distance of 2.5 x 2.5 m and with a height of 1.5-2 m. Fix one layer of GI wire no. 14 at the top of each row and column. Fix two layers of GI wire # 18 at a distance of 3 ft below the upper layer of the row only. Fix a layer of plastic string on top of the trellis foundation at 20 cm apart, then fix abaca string or dried banana bracts string vertically from the upper wire layer to the bottom wire layer for the vines to crawl on.
Crop Procedure Break the seed coat lightly and soak the seeds in water for 24 hours, then wash. Incubate for 24-48 hours until the radicles appear. On the first day, plant the seeds with uniform germination to have a uniform stand of plant in the field. Plant the second flush on the second day then throw all the slow germinating seeds. Incorporate organic fertilizer 25
at the rate of 50 g per hill before planting. Plant one germinated seed per hill at a depth of 2 cm and spaced at 50 cm along the row.

CHAPTER V SUMMARY, CONCLUSION AND RECOMMENDATION
SUMMARY Organic
fertilizer
provides
better
appearance
and
sufficient nutrients needed by the plants while inorganic fertilizer
provides
poor
appearance
but
still
provide
sufficient nutrients needed by the plants.
29
Organic fertilizer provides longer life to the plants while
inorganic
fertilizer
provides
shorter
life
to
the
plants due to the damage of the fertilizer to the soil. Organic
fertilizer
provides
a
wider
leaves
while
inorganic fertilizer provides smaller leaves than organic. Organic fertilizer takes time to grow the plant while inorganic fertilizer forces the plant to grow faster. There is no significant difference between the rates of application
of
organic
fertilizer
to
the
plants
while
inorganic fertilizer shows difference between the rates of application to the plants.
CONCLUSION We therefore conclude, that the comparison of using organic and inorganic fertilizer is really helpful for the farmers, if what should they used for better and effective production. Organic fertilizer can create a wider leaves and also remains the nutrients of the soil. The importance of organic fertilizer is that the plants that are going to plant is healthy and have a longer life so that the farmers 30

production and addition to it, its leaves are green than inorganic fertilizer. And when inorganic fertilizers have been used, the effect of it on the plant is that, it grows longer than organic fertilizer, but be careful with the measure of inorganic fertilizer because there is chances of getting loosen the plants and the soil also. Using the right amount of inorganic fertilizer is very important because the result depends to the application of fertilizer.
1.
The
comparison
between
organic
and
inorganic
fertilizer were, the organic fertilizer applied with the total of 5 kilos, from 1 inch with a colour of yellow green and width of 0.50 inch of leaves gets 5 inches with the colour of green and width of 3 inches of leaves due to the application of organic fertilizer, then after 2 weeks when the fertilizer was applied again with the total amount of 3 kilos, from 5 inches gets 4ft. with the colour of dark green and 4.5 inches of leaves. While when inorganic fertilizer was applied with the total of 1tbs, from 1 inch length, with the colour of yellow green, width of .50 inch leaves gets 6.5 inches length, colour green and width of 2.5 inches of leaves and after 2 weeks when the fertilizer applied again 31
with the total amount of 1 ½ tbs, from 6.5 inches gets 5 ft with the combination of color green at the top and green at the bottom and width of 4 inches of leaves due to the excessive use of inorganic fertilizer. 2.
The
comparison
between
organic
and
inorganic
fertilizer were, the organic fertilizer applied with the total of 6 kilos organic fertilizer, from 1 inch with a colour of yellow green and width of 0.50 inch of leaves, the latter turn into 5 inches with the colour of green and width of 3 inches of leaves due to the application of organic fertilizer.
Then
after
2
weeks
when
the
fertilizer
was
applied again with the total amount of 4 kilos, from 5 inches, the plant turns into 4 feet with the colour of dark green
and
4.5
inches
of
leaves.
While
when
inorganic
fertilizer was applied with the total of 1 ½ tablespoons of fertilizer, from 1 inch length, with the colour of yellow green, width of .50 inch leaves turn into 6.5 inches length, colour green and width of 2.5 inches of leaves and after 2 weeks the fertilizer applied again with the total amount of 2 tablespoons, from 6.5 inches turn into 5.38 feet with the combination of colour green at the top and green at the bottom and width of 4 inches of leaves due to the excessive use of inorganic fertilizer.

As a researcher, we would like to recommend of using organic fertilizer because base in our experimentation and observation it helps the soil to lessen the acidity and plants to grow healthy, so that it will avoid the plants from
other
diseases.
Using
organic
fertilizer
helps
the
farmer to save their money or spend it in just a minimum cost. Rather than inorganic fertilizer that can grow faster however the plants die in just a short period of time. And the costs of the farmers get higher because there are a lot of chemicals needed to apply for the production.
