What is The Effect of Nitrogen Percentage on The Height of Grass? If the percent of nitrogen is higher, then the height of grass will increase. The independent variable of this experiment is the different percentages of nitrogen. The dependent variable is the height of grass. The control group is the soil from the backyard while the experimental groups are the potting soil and Haw River soil. One cup of soil and five mL of Pennington Tall Fescue grass seed will be placed in each container. Three cups of waters will be given to the grass every other day and the height of the grass will be measured every week. At the end of the experiment, potting soil with 21% nitrogen had the highest grass grown. The backyard soil was the second highest grass grown with 17% nitrogen and Haw River had the shortest grass with 13% nitrogen. If the percent of nitrogen is higher, then the height of grass will increase. The purpose of this lab is the see how much nitrogen should be used to grown the best, tallest grass or plants. Nitrogen is a part of all living cells and is a necessary part of all proteins. “The primary use of …show more content…
Grass that was planted in soil with 13% nitrogen grew to be 8.1 cm but grass that was planted in 17% nitrogen grew to be 8.3 cm. However, grass planted in soil with 21% nitrogen grew to be 9.1 cm. Therefor, as the amount of nitrogen present increases, the height of grass increases. Plants need sunlight to grow. Sunlight is used during photosynthesis to make and build the parts of plants like the roots and leaves. Nitrogen helps plants with growth and seed/fruit production. Nitrogen is apart of chlorophyll, which is responsible for photosynthesis. So as shown in this experiment, the same amount of sunlight and the amount of nitrogen that is given affects the plant’s growth. If nitrogen levels decrease, the height of the plant also
There are two of three radish farms in Ensi county, IN have gone through crop failure. The study of the crop failure is being experimented on so the reason for the failure can be stated. The investigation was on how well the radish seeds grew in five different types of water taken from different locations within a five day period. Site A was the control of the experiment so the data taken on the other sites could be compared to site A. Sites A, C, and E grew while sites B and D did not grow at all. The salt storage facility has a leak that is causing salt to flow into the river where the 2 radish crops are failing. The data show that sites B and D aren't growing
The experiment was done to test how the amount of fresh water affect the growth of the wheat plant. Wheat is an important commercial crop grown in mostly all the parts of the world. There are many different products which are the product and by-product of the wheat plant. (Majsztrik et al.2017) So, if the yield of the wheat plant increases than it is going to benefit the farmers and also the consumers. The experiment was based on the hypothesis that, if the amount of water is decreased the height of the plant will also decrease. The results supported the hypothesis. So, we can say that if the amount of water the wheat grass gets during its growth is improved with the different techniques of irrigation, then the production of
In my experiment, I decided to look at how or if different liquids effect the growth of a tomato plant. The independent variables in this experiment were the liquids that the tomato plants were watered with. The dependent variables in this experiment were the speed that the plants grew and the amount that they grew throughout the two weeks that they were measured. I hypothesized that if the tomato plant is watered with river water, then the plant will grow the tallest.
1. For this experiment, what were the independent variable and the dependent variable? What were the constants?
Protein: (formerly) a substance thought to be the essential nitrogenous component of all organic bodies
However, for each quad, the fertilizer used for the control was added altogether with the fertilizers being studied. Since the only plant that presented growth was in the control quad, it becomes necessary to explore the effects of excess fertilizers, and furthermore, excess nitrogen, would have in the development of the fast plants. Although Nitrogen is one of the elements most living organisms require, some studies have showed high levels of nitrogen can cause toxic stress to some plants, to the point where growth can be inhibited. (Yu et al.

In an experiment, there are variables that need to be controlled and observed. They are the independent and dependent variables and the control variables. The independent variable is the variable that you are testing. The dependent variable is what you observe for change. The control are the ones that stay the same. In the experiment “Will the growth of the plant be affected by the color of the light”, the plant that has the white light will be the control variable, while the plants that have different light colors will be the independent variable which is what is being tested. The dependent variable will be the growth of the plant since that is what you are measuring or
Would putting plants at a higher elevation from the ground effect it’s growth speed? Would this actually work ? The experiment was conducted to find out how much plants would grow at different elevations. To conduct this experiment, you must first take a species of plant (sunflower). Once you have these, place one of each plant at different elevations. After this, you will just need to observe the plants for a week to see how much they grow. When all the steps are completed, you must measure the growth over the course of one week. This resulted in the sunflower at the higher elevation to grow 1.3 cm higher than it’s original height, 5 cm. On the lower elevation, the sunflower grew approximately 1.7 cm higher than it’s original height,
In this experiment, I tested the theory of how light would affect the growth of a bean plant. According to gardenguides.com, lack of light is detrimental to plant growth.”Plants that don't get enough light don't have the resources they require, and fail to bloom or fruit.” It is also stated that every plant will need a different strength of sunlight such as full sun, partial sun, or indirect sunlight (also known as full shade). Plants that receive inadequate amounts of sunlight will not thrive.The reasoning behind this is due to a process called Photosynthesis, stated in gardeningknowhow.com. Photosynthesis is a chemical process which converts energy in the form of light into a chemical energy which is a vital food source for plants to thrive.

I am interested to see how the levels of nitrogen in the young saplings, measured from the leaves of randomly chosen plants, affects the rate at which they grow around the radius of their trunks and whether there is a significant relationship between the two. I would expect that certain levels of nitrogen are the most optimal for the growth of a sapling where enough is present to allow the most efficient production of photosynthesis in its leaves as the energy produced in this process would allow growth throughout the rest of the plant. At very low levels I could expect growth rates of saplings to be very slow or not at all and as the nitrogen levels in a sapling’s leaves increases for the growth rate to increase to a certain extent. There would however be likely a point where an increase in nitrogen levels does not mean a higher growth rate as too much can be detrimental to other components in a sapling’s health,

There are restrictions of nodule formation in the non-limiting side of the plant when one side of the plant is nitrogen deficient in order to maintain the optimal nitrogen content.
