CHAPTER I. INTRODUCTION
A. BACKGROUND OF THE STUDY
The Philippines is one of the world’s “mega biodiversity” countries, rich in both fauna and flora, and even if we are rich in all of these, the sector of our agriculture is now facing many kinds of problems. With the big mass of population in our country which is about 101,664,929 as of Monday, February 15, 2016, based on the latest United Nations estimates, this only shows that more and more, our country’s employment and economy will be dependent in the sector of agriculture.
We all currently rely on industrial agriculture to produce the majority of the food we eat; this type of agriculture is facing problems that may threaten its future. ...view middle of the document...
Even though Organic and Inorganic fertilizers have their different effects when it comes to the nutrition of plants and its effect on the soil, it has the main objective, and it is to help farmers in hastening plant growth. Inorganic fertilizers are mainly from petroleum or natural gas and are manufactured for commercial purposes; these kinds of fertilizers are primarily acquired from chemical compounds such as ammonium nitrate [(NH4) (NO3)], ammonium phosphates [(NH4)3PO4] and potassium chloride (KCl). Chilean sodium nitrate, mined rock phosphate and limestone are just few from the many kinds of inorganic fertilizers.
Some of the disadvantages of using inorganic fertilizers are the “burning” or desiccation of plants and distort ion of the soil quality that can lead to cadmium poisoning if the fertilizer is used too much or applied in a wrong way. Usage of inorganic fertilizers requires strict watering schedules in order to retain the soil moisture. Also, inorganic fertilizers are mainly from petroleum or natural gas that come from mines or saline lakes, thus from limited resources (Types of Fertilizer, 2007).
Hydroponics is a technique of growing plants using another medium other than soil to provide nutrients to the plant (Hydroponics, 1995). The fertilizer is dissolved in water and transported to the plant’s roots to supply the plant with its needed nutrients and minerals. The fertilizer dissolved in water is called nutrient solution (Hydroponics Gardening, n.d.). The researchers will use the hydroponics system in examining the effect of commercial fertilizers in the growth of Pechay plant, and the acidity of its soil.
B. STATEMENT OF THE PROBLEM
This study aims to investigate the feasibility of three different commercial fertilizers for Pechay (Brassica Rapa) in terms of (a) height, (b) number of leaves, and (c) weight using hydroponics technique, (d) determine if there is any significant difference on Pechay growth rate.
a) Among which fertilizers had a significant difference between the (a) height, (b) length of leaves, (c) weight using hydroponics technique, and the (d) growth rate of each of the samples of Pechay plant?
HO: There is no significant difference between the (a) height, (b) length of leaves, (c) weight using hydroponics technique, and the growth rate of each of the samples of Pechay plant.
HA: There is a significant difference between the (a) height, (b) length of leaves, (c) weight using hydroponics technique, and the growth rate of each of the samples of Pechay plant.
D. SIGNIFICANCE OF THE STUDY
Organic fertilizers improve the structure of the soil, helping it to produce large amounts of goods, crops, or other commodities because it mobilizes existing soil nutrients like nitrogen. Consistently as micro-organisms in the soil break down the organic material down into inorganic water-soluble form which the plants can use. Organic fertilizers continue to moisture the soil and do not remove the moisture...
