Introduction

A. Background of the study. Plants need to be fertilized because most soil does not provide essential nutrients required for optimum growth. Even if the person is lucky enough to start with great garden soil, as your plants grow, they absorb nutrients and leave the soil less fertile. Nutrients in the soil also help plants grow strong. Some nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Fertilizers, also known as food elements, are materials produced to supple these elements in a readily available form of plant use. It helps to make plants grow faster which help some farmers and gardeners for their business. Choosing the right fertilizer help us to get everything we need from the plants we eat or from the meat of animals that eat plants. Plants are factories that do all of the work to process the basic elements of life and make them available to us. Fertilizers help feed the world. The FAO has stated that “after land and water, fertilizers are probably the most important input leading to increased yields”. It is inherently difficult to estimate the share of fertilizers in increasing agricultural output since so many factors are involved. It has been estimated that fertilizer contribute about 40% of the nitrogen in human protein consumption, it follows that nearly one third of this protein depends on fertilizers. Therefore, it is important for us to know which fertilizers to use for us to sustain properly the needs of every plant. Increased crop production largely relies on the type of fertilizers used to supplement essential nutrients for plants. Fertilizer application is required to replace crop land nutrients that have been consumed by previous plant growth with the ultimate goal of maximizing productivity and economic returns. Now a day, there is increased emphasis on the impact on soil environment due to continuous use of chemical fertilizers. The impact of chemical fertilizer application on agricultural land is seen not only in terms of the soil quality but also on the survival of soil organisms dwelling there in. Chemical fertilizers provide three major plant nutrients; nitrogen, phosphorus and potassium or NPK. However, the ever increasing cost of commercial fertilizer products driven, in part, by the inevitable depletion of global phosphorus, is forcing producers to look for alternative sources like bio-fertilizers and other organically-based solutions. In literature, some researchers have concluded the chemical fertilizers to be harmful for soil organisms but on the contradictory they have been supported too to be beneficial as far as their food supply is concern. The primary advantages of using biosolids as a fertilizer alternative are cost efficiencies and

the presence of nutrients and organic matter. Returning these valuable materials back to the soils is a critical element in long-term sustainability.

B. Statement of the problem This research aim to compare 2 different brand of fertilizer: Chemical fertilizer and Citrus Sinensis Peeling (biofertilizers), specifically the researchers sought to answer the following questions: 1. 2. 3. 4.

How does the researchers determine the effectivity of these product? What are advantages and disadvantages of using these fertilizers? Which fertilizer will make plants grow faster and healthier? Which fertilizer is better and more safe to use: Citrus Sinensis Peeling or branded fertilizer?

C. Hypothesis The researchers will determine the effectivity of the product by testing the effectivity of 2 brand of fertilizer in separate plants (Plant A and Plant B). After the testing, the researchers will record the result and make a statement about the research.

D. Significance of the study. The study are beneficial to: 1. Farmers and gardeners- the benefit of this study will help them to improve the quality of their products, save time with their work, and get a higher profit. 2. Environment- the benefit of this study will help our environment by helping the soil and plants to sustain their needs and provide the essential nutrients required for optimum growth. 3. Agricultural company- the benefit of this study will help them to give a good service to their customers by giving them a high and good quality products (ex: rice, vegetables, and fruits) 4. Community- the benefit of this study will help the community to sense this as a source of income if made into a business.

E. Score and Limitation

The following information of this research will come from different textbooks, surveys of different researchers, information stated of the product, and some information in the internet about the subject which is plants and fertilizers. The factors to consider covered by this study are to evaluate the effectiveness, cost, and functionality of the fertilizer. Through the study shows high feasibility, there are still boundaries that shall be set to further facilitate the research process. In the study, there shall be two setups; thus set-up A: plant fertilized with citrus sinensis peelings, set-up B: plant fertilize with branded fertilizer. The researchers will then identify its difference. This study will last for 3-4 weeks. This study can be done until march and the result should be presented at the statement. However, there are limitations of the study which is stated below. The following limitations are:    

Sunlight is one of the important materials in doing this study. Without sunlight, this experiment can’t be processed. Some informations gathered from surveys, questionnaires and reference materials. Cost and availability that will be covered from this study. Time management

F. Definition of terms. The following technical terms are defined in this study.      

I. II.

Nitrogen- tasteless odorless gaseous chemical element Phosphorus- poisonous waxy chemical element Potassium- silver white metallic chemical element Calcium- a soft gray alkaline earth metal, fifth most abundant element by mass in the earth’s crust. Sulfur- an abundant, multivalent non-metal Citrus Sinensis- the scientific name of sweet oranges. It is what most consumers commonly buy.

Review of related literature: Experimentation. The research about the comparison between 2 different brand of fertilizer was aimed to help the community to be aware of the importance of fertilizers and also to give them the information in which fertilizer to use

for their plants. Books, internet, and other references materials were used as the primary sources of information to strengthen the researchers’ view on this topic. But these were not enough, so experiments were conducted by the researchers to gain additional information. A. Materials:  Pot A and Pot B  Good quality of soil  Seeds to be use (any kind of plant: pechay)  Water  Sunlight  Branded Fertilizer  Orange peelings

B. Methodology Procedures: 1. 1. Sow seeds thinly on shallow furrows across the seed pot, and cover lightly with fine topsoil. Do not broadcast seeds when sowing to avoid thick germination in one place. 2. 2. Water the seed pot daily. Watering and other cultural management practices should be regularly done. 3. 3. Apply liberal amount of fertilizer (Citrus Sensis Peeling for pot A and branded fertilizer for pot B) at the base of the plants, then cover lightly with soil and water immediately. 4. 4. Water the plant whenever necessary or depending on your own judgement or observation of the plant 5. 5. Always remember to give both pot a presence of sunlight for their process of growing. 6. 6. Every week, measure the height of both plant. 7. 7. Observe 8. 9. As long as the researchers followed the procedures, success of experimentation will be achieved. Factors such as sunlight could affect the study. In addition, if this is not available, possible that this study could fail. However, researchers could try it once more again and again until the study is evaluated.
