Abstract
Among many types of fertilizers, most widely used ones are chemical and organic fertilizers. Chemical fertilizers are specialized fertilizers that their nutrient level is controlled by the production process. On the other hand, nutrient levels (nitrogen-potassium-phosphorus) of organic fertilizers are determined by their type such as vermicompost, poultry manure, farmyard manure, bat guano, and compost. These types differ from one another by nutrient levels. Although nutrient levels of those have literature values and researches about it, there is no data about application of organic fertilizers on a specified plant. The objective of this investigation is to find out how much a plant, in this case Zea mays (corn plant), can transfer the nutrients into its system via roots with respect to the fertilizer type. 5 types of organic fertilizers are used to grow Zea mays and NPK calculations are made by using different measurements, resulting in finding out the percentages of nutrients in the body of the plants. It was revealed that poultry manure had the largest impact on plant growth, resulting in having a greater dry and fresh weight, higher potassium and phosphorus percentage. Vermicompost was the least effective among the organic fertilizers, at the same time, other fertilizers were moderately effective such as farmyard manure, compost, and bat guano. On the whole, the hypothesis is proved to be wrong, as vermicompost did not match the expectations of being the most effective. The reasoning can be made from the point that the nutrient release effect is slower as a result of worm activity, while other type of organic fertilizers have more nutrients available for the plant in the same time period.
