CHAPTER ITHE PROBLEM AND ITS SETTING

IntroductionIn 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 faces the challenge of increasing production to provide food for the growing population. Increasing population puts pressure on the cultivation of marginal land areas and results to land degradation and decline in soil 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).Fertilizers are a major cost item in Philippine agriculture. They increase yield and enable the country to attain sufficiency in food and agro-industrial crops. Fertilizers have also made crop production possible in unproductive soils. Fertilizer is believed to contribute 30% to 50% of the increase in yield in crops. However, high fertilizer prices have become a cause for concern since they squeeze farm incomes.Organic 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, it adds more natural nutrients, feeds important microbes in the soil and improves the structure of the soil.Organic fertilizers are known to have a bad smell. Many organic fertilizers are released slowly so your flowers and plants will stay nutrient deficient until the process of decomposing is finished. Because organic fertilizers contain lower percentages of the three key nutrients; nitrogen, phosphorus and potassium, you may need to use more to make sure that your plants are getting the right amount. Organic fertilizer is rapidly growing in favor, because it provides and recycles supplemental nutrients to crops and its non-chemical 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 in combination with crop rotation, cover cropping, green manuring, liming, and the addition of other natural or biologically-friendly fertilizers and amendments.Inorganic fertilizers are sometimes completely, or at least partially, comprised of man-made materials. Normally, manufacturers combine specific kinds as well as amounts of different elements. This is according to the growing condition that is needed, as well as the crop that is 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). 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 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 to use other method like applying different organic fertilizers.The researchers focused on the comparison between the use of organic and inorganic fertilizer in agriculture as the main source of income of the citizens in the country and so as to identify the best way on what strategy or strategies will be used to harvest and earn more profit from the crops.

Conceptual FrameworkGrowing root crops using organic and inorganic fertilizer has different advantages and disadvantages. But the main objective of using these fertilizers is to produce 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 FrameworkThe theoretical framework of this study is consisted of two subjects namely, organic and inorganic fertilizer.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 ParadigmThe research paradigm of the study is illustrated in Figure 1. It is contained process leading to answer the problems of the study, namely: (1) Effectiveness of organic fertilizer; and (2) Comparison of organic and inorganic fertilizer. All the answers to these questions could lead the researchers to come up with the idea on how organic and inorganic fertilizer greatly affects the production of bitter melon.The research paradigm input box contains items to be collected and process such as the effectiveness of organic fertilizer, and the comparison of organic and inorganic fertilizer.In the process box, unstructured interviews to farmers, observation and experimentation to the plant were conducted by the researchers.In the output box, the purpose of the researcher is to identify the comparison and effectiveness of organic and inorganic fertilizer on the production of bitter melon.

ColourThe colour is the appearance of something that has a result of the way in which it reflects light (Webster dictionary). The term is used to describe the appearance of the leaves in the study.CropsThese are the plants that are grown in large quantities for food. The term is used as the main subject of the study.FarmerHe is a person who owns or manages a farm. The term is used as the one who plants the crop.FertilizerIt 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 fertilizerIs a chemical which are not come from the living things. This term is used for the easier and faster growth of the plant.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 plants height.

LivestockAre 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.ManureIs animal faeces, sometimes mixed with chemicals, that is spread on the ground in order to makes plant grow healthy and strong.

CHAPTER IIRELATED LITERATUREThis chapter presents the review of related literature on the subject. Several studies will discuss some aspects of the research work, or in some way may give a better understanding into the research problem, and those in which one way or another will prove to be useful to the writer. The review of related foreign literature will focus on two variables, namely organic and inorganic fertilizer.

Foreign LiteratureResearch comparing organic and inorganic fertilizers provides compelling evidence that organic fertilizers bolster soil health over the long term. In a study conducted in Sweden over 32 years, scientists Artur Granstedt and Lars Kjellenberg reported on the differences in soil structure and crop quality between an organic and inorganic system. They found that soil in the organic system had higher fertility, and organic crops had higher yields and starch content than the inorganic system. In contrast, long-term use of synthetic fertilizers depletes soil organisms of the organic matter they need, states the Maine Organic Farmers and Gardeners Association. Eventually, these organisms 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 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 fertilizer need to go through a mineralization process in which soil microbes convert organic N compounds into ammonium and a subsequent process that quickly oxidizes the ammonium to nitrate (Gaskell and Smith, 2007). Mineralization determines the rate and availability 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 the University of Georgia extension service recommends growers consider 50% of the N, 90% of the phosphorus (P), and 100% of the potassium (K) in raw poultry litter as available the first year after field application (Kissel et al., 2008). How litter-based fertilizer behaves in an actual greenhouse setting remains a significant question.The frequent use of fertilizers is an important part of agricultural production around the world (Chand et al., 2006). For several years, major crop producers have preferred the use of inorganic fertilizers due to its high yield in crop productivity. However, long-term applications of inorganic fertilizers have caused a noticeable decrease in crop productivity and an increase in pollution around its surrounding environment (Chand et al., 2006). Recently, many agricultural companies have shifted from using inorganic fertilizers to organic fertilizers (Luo et al., 2006).A study was conducted to determine the yield responses and leaf nutrient concentrations broiler chicken manure had on lima bean production (Luo et al., 2006). Two fertilizers were tested: organic broiler manure (BM) and inorganic ammonium nitrate (AN). During the first year, 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 split into three separate, but equal applications. Along with the fertilizers, water was also applied to the 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 of organic manures, 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 of essential oil of European and Reunion basil crops. There were six treatments (T) used to grow the basil crops. T1 was the control consisting of only water; T2 was the farm yard manure (FYM); T3 was the vermicompost, an organic fertilizer consisting of a mixture of partially decomposed organic waste, bedding, and worm castings; T4 was the inorganic fertilizer, a standard mixture of nitrogen, phosphorous, and potassium (NPK); T5 was a combination of FYM and NPK fertilizer; and T6 was a combination of vermicompost and NPK fertilizer. The setup was a randomized block design (RBD) with four replications of each plant. The treatments consisting of FYM, vermicompost, and NPK fertilizer alone were applied to the soil before planting. The two combination treatments were applied twice, once at the time of planting and an equal amount was applied a month after planting. After a period of 3 months, the crops were harvested. The essential oil from each plant was extracted, and fresh weights were recorded in each plot. Results showed that the application of T2 thru T6 showed a significant increase in fresh weight, dry matter, and oil yield in the basil crop over the control (T1). The application of FYM alone showed the lowest increase over the control and the application of a combination of vermicompost with NPK fertilizer showed the highest increase over the control followed by the combination treatment of FYM and NPK fertilizer. Mean herb yield of the plants grown with NPK fertilizer alone was significantly higher than the treatments consisting of either of the organic manures applied alone. However, each of the combination treatments resulted in greater fresh weight yield and dry matter yield than the organic or inorganic fertilizers alone. Previous studies conducted by Patra et al. (2000) and Chand et al. (2001) also reported similar results in menthol mint crops. At the end of the study, Anwar et al. (2005) concluded that the application of organic manure, combined with a minimum dose of inorganic fertilizer, was better than inorganic fertilizer or organic manure alone for yield, nutrient uptake, and quality of basil.A similar field experiment was conducted by Chand et al. (2006) on mint and mustard crops in subtropical India. The setup was also similar, consisting of a RBD with 8 combination treatments composed of different ratios of FYM and inorganic fertilizer and replicated three times. T1 was the control, T2 was FYM alone, and T3 to T8 were inorganic fertilizers with different NPK (nitrogen-phosphorous-potassium) ratios mixed with various amounts of FYM. All treatments were applied continuously to the crops for 7 years.First, the mint seeds were planted, immediately followed by irrigation. Irrigation was then applied every 10 15 days (Chand et al., 2006). Half of each treatment was applied at the time of planting, and the remaining half was applied 48 days after planting. At maturity, the crop was harvested and weighed. Dhaincha, a weed commonly grown in India to restore nitrogen to depleted soils, was sown and plowed down after 45 days to allow for its decomposition. Next, mustard seeds were sown and a full supply of NPK fertilizer was applied. The crop was harvested 4 months later and weighed. Results from the experiment showed that the highest increase in dry matter was in T4, which was NPK 133:40:40 fertilizer mixed with an equal amount of FYM as in T3, with an increase of 92.8% over the control (T1). Chand et al. (2006) concluded that a combination of organic manure and inorganic fertilizer increased the yield and dry matter of mint and mustard crops.

CHAPTER IIIRESEARCH METHODOLOGY

Research Design or MethodAccording to L. Given (2013) descriptive research provides a detailed account of a social setting, a group of people, a community, a situation, or some other phenomenon. This kind of research strives to paint at complete and accurate picture of the world by focusing on the factual details that best describe a current or past event.Descriptive research design is a scientific method that involves observing and describing the behavior of a subject without influencing it in any way. The purpose of descriptive research is the exploration and description of phenomenon in real life situations. This approach is used to generate new knowledge about concepts or topics about which limited or no research has been conducted. Through descriptive research, concepts are described and relationships are identified that provide a basis for further quantitative research and theory testing the survey type of description research is employed to collect information from the subject matter of the study.

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 independent variable is manipulated. 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 fertilizerCombine 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 blends well and so it decomposes for about approximately one week.

Land PreparationPlow and harrow the field twice. After the second 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 ProcedureBreak 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 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 VSUMMARY, CONCLUSION AND RECOMMENDATION

SUMMARYOrganic 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.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.

CONCLUSIONWe 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 who are going to used it can reduced the cost in the 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 with the total amount of 1 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 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.3. The comparison between organic and inorganic fertilizer were, the organic fertilizer applied with the total of 7 kilos, from 1 inch with a colour of yellow green and width of 0.50 inch of leaves gets 5 inches with the color 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 gets 4ft. with the colour of dark green and 4.5 inches of leaves. While when inorganic fertilizer was applied with the total of 2tbs, from 1 inch length, with the colour of yellow green, width of .50 inch leaves gets 6 inches length, colour green and width of 3 inches of leaves and after 2 weeks when the fertilizer applied again with the total amount of 2 table spoon, from 6.5 inches gets 5.5 feet with the combination of colour green at the top and green at the bottom and width of 4.5 inches of leaves due to the excessive use of inorganic fertilizer.

RecommendationNowadays, most of the people agriculture is the main source of income. So farmers can either used organic or 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.
