Introduction
Background of the study. Rotten fruits and rotten vegetables can be good compost rather than taking commercial fertilizer.
Statement of the Problem. What is the effect of the rotten fruits and rotten vegetables to the growth of tomato plant in terms of :
- Height
- Number of leaves
Hypothesis. Using rotten fruits and rotten vegetables will not make a difference in the growth of tomato plants
Significance of the study. The significance of the study is to save money, to help the environment, show others how to use alternative fertilizer and to recycle and learn how to take care of plants and make it a hobby.
Scope and limitations. The kind of fruits and vegetables that we used are apples and kangkong, the kind of plant that we used are tomatoes, and the kind soil that we used is loam soil.
Related Literature and studies
The important factors affecting plant growth and development include heredity, hormones, nutrition and environment. Roots
Roots in the plant store food, water and minerals Root growth substances which are produced in leaves and responsible for the regulation of root growth. 3 vitamins for root growth
Thiamine (Vitamin B1):
B1 is produced in the foliage of plants and transported down to the root system where it has an effect on root growth and development. In tissue culture and rooting preparations, B1 helps to stimulate the growth of roots on new plants but this is best used in combination with rooting hormones.
B1 can assist at any time in a plant’s life with root regeneration where the root system has been damaged or stressed through high salinity, pathogens such as pythium, nutrient deficiencies and toxicities, high fruit loading etc but only if the foliage of the plant is unable to produce sufficient supplies for this purpose. Use of B1 is seen as a ‘back up’ or ‘insurance policy’ as it is difficult to determine if a plant which has come under stress is capable of producing sufficient B1 to send down to the root system to assist in cell development. se of Vitamin B1 in plants is the same as in humans – it is most useful where a deficiency exists for some reason.
B1 is best applied as a seed soak to speed up germination (root growth), or as a foliar spray. B1 is an organic compound and as such is rapidly broken down by microbes in the nutrient solution (they love to eat carbon based compounds), adding high amounts of B1 may ensure sufficient thiamine stays in the nutrient for a few hours for some plant uptake, but generally microbes will break this down rapidly as well.
Pyridoxine (vitamin B6):
is a cofactor required by numerous enzymes in all cellular organisms. Plants are the major source of vitamin B6 for animals, yet the biosynthesis pathway and the function of vitamin B6 in plants are not well elucidated. In this study, an Arabidopsis pyridoxine synthase gene PDX1 was characterized and its in vivo functions were investigated.
The PDX1 gene was expressed in all plant parts examined and its expression level was not significantly regulated by abiotic stress or the phytohormone abscisic acid. In roots, PDX1 was highly expressed in a defined region behind the root tips that undergoes rapid cell division. The PDX1 protein was mainly associated with the plasma membrane and endomembranes, implying a potential involvement of vitamin B6 in membrane function. To reveal the in vivo role of PDX1, Arabidopsis insertional mutants were isolated. Strikingly, the pdx1 knockout mutants were impaired in root growth and early seedling development.
The stunted roots resulted from both reduced cell division and elongation. Supplementation of the growth media with pyridoxine or reintroduction of the wild-type PDX1 gene into the mutants completely restored the mutant growth, demonstrating that PDX1 is required for pyridoxine biosynthesis in planta.
In addition to the developmental defects, pdx1 mutants are hypersensitive to osmotic stress and oxidative stress. These mutant seedlings had increased peroxidation of membrane lipids following UV treatment. Our study establishes a critical role of vitamin B6 in plant development and stress tolerance and suggests that vitamin B6 may represent a new class of antioxidant in plants.
Niacin (vitamin B3):
Other experiments showed that niacin is a root growth factor, and is presumably also a root growth hormone. In various combinations thiamin, pyridoxin or niacin will support the indefinite growth of isolated roots of many species. For a few species other factors are required such as the amino acids glycine, lysine and arginine. The factors for a plant to grow
The type of soil, soil is important for the plant to stand and get water, minerals and vitamins. The growth of plants are always based on the cell and increasing the spore of plants. Growth also gives the pants the ability to adapt to their environment. Plants use their metabolic processes: photosynthesis, respiration, and digestion to live by chemical changes.
Without plants, nearly all life on earth has no reason to live. Most living things depend on plants for food. But also we depend on plants for the air we breathe. In short plants have many uses.
Methodology
Experimental design. The independent variable is the type of fruits, and the dependent variable is the growth of the tomato plants (height and no. of leaves).
Procedure
First is, to gather all the materials then, mash the fruits in one container then mash the vegetables in another container then put 5g of mashed fruits in another container and mix it with 5g of mashed vegetables then mix soil in all containers then the container with the fruits only, put it on a pot then label the pot A then, the container with the vegetables only, put it on a pot then label it B, then the container with the mixed fruits and vegetables, put it on a pot then label the pot C. (If the level of the soil is low add more soil it is okay if you don’t mix it.) After you have done this just leave it there for a day, the next day you can now plant your seeds. So in each pot you must plant at least 4 seeds and water your plants daily about 400ml per day.
Materials
The materials are cheap and not hard to find, you can just buy them at the market. Well this is our list of materials: tomato seeds (1 pack), 3 Flower pots, 2 bags of soil,3 large containers, rotten fruits and rotten vegetables .
Summary
After we arranged our materials, we mixed the fertilizer with soil. In pot A, there are rotten fruits mixed in the soil, in pot B there are rotten vegetables mixed in the soil, and in pot C are both rotten fruits and rotten vegetables mixed in the soil, then we planted 3 seeds in each pot. Unfortunately one of our members did not take care of the plants, so the two plants B and C did not sprout, only plant A had sprung.
Conclusion
Based on the experiment, the pot with rotten fruits is the only one with plants on it, so our conclusion is that, using rotten fruits is more effective than using rotten vegetables.
Recommendation
Our recommendation in this project is to take care of the plants seriously, and to buy or get the best quality of all the materials especially the seeds you’re going to use.
