Introduction
Plants grow and reproduce and in order to do so they need certain resources. Both external and internal resources partly determine the plants development. Common resources are water, space and nutrient obtained from either the plant’s environment or food. They get sugar through photosynthesis using water, light, CO2 and other necessary nutrients. Plants require nutrients to build molecules so reactions can take place that are required for the plant growth, maintenance and reproduction (Rush, Gladilina and Condy 2014). These nutrients usually are taken up by the plant through their roots and leaves. Nitrogen is the most important nutrient to plants, as it is a macronutrient and needed in large amounts for plants (Rush,

The purpose of this research is to find out how nutrients, such as phosphorus and nitrogen affect plant growth. To find out how the plants are affected by growth in the different nutrient treatments. With the results found, what does this suggest about how people should fertilize the soil in which people grow food crops. Using the species of grass rye, the research investigates the effect of the absence of nitrogen and phosphorus.
By using three different treatments, a full complement of nutrient, a full complement without the most important nutrient, Nitrogen and a full complement of Phosphorus, the length of the root and shoot and the biomass are observed and analyzed. If nitrogen was deprived from the rye seedlings growth process then the biomass, shoot length and root length will be affected more than depriving the rye seedlings from phosphorus. The null hypothesis would be, if rye was deprived the nutrient phosphorus, then it would have a larger effect on the rye seedlings shoot length, root length, and biomass than depriving the plant from nitrogen.
Materials and Methods
Obtain a planting container. Cut one paper towel in half, fold and place on the bottom of the container. Cut a layer of cotton to fit at the bottom of the container and place it on the paper towel. Use the other half of the paper towel, fold and place it on top of the cotton. Add 30 ml of the media solution into the container and allow the
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
Plants need food to grow like human beings. Fertilizers can provide plant’s nutrients that may be lacking in the soil. How does the amount of fertilizer effect the growth of the plant? Plants are important in our life. Plants give us food, regulate the water cycle, and provide us oxygen. Plants make up the habitat, and contribute to the climate. Our everyday life depends on plants. Life could not exist without plants. It is very important plants grow and develop properly. Lack of water, nutrients in the soil, and natural disasters may contribute to the delay or reduction of the plant growth. If a plant does not get the right amount of nutrients from the root then the plant will not yield fruits, crops, and flowers. Plants need the right amount of fertilizer to grow and develop. Usage of too much fertilizer can harm plants. Plant can suffer from dehydration and eventually die. The correct amount of fertilizer is essential for the plant to grow healthy. If watering the plant with too little or too much fertilizer, then plant’s growth will slow down, because under fertilizer will cause the lack of nutrients in the soil and over fertilizer will increase the salt amount of soil which eventually slow down the growth of the plant.
In order for plants to grow they require many things. They need water, nutrients, soil, air, light, temperature, space and time. Since water is vital to a plants growth, most plants use water to transport moisture and nutrients back and forth between the roots and leaves. The water contains nutrients and is taken through the roots up to the plant. Along with carbon and oxygen, that are absorbed from the air, and water which is found in soil, plants must obtain other essential elements to grow, such as nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, boron, chlorine, manganese, iron, zinc, copper molybdenum, nickel and hydrogen. The three primary nutrients plants need to grow are nitrogen, phosphorus and potassium. Nitrogen
Plant foods contain three essential nutrients that are not readily available from soils. These are soluble compounds of nitrogen, phosphorus, and potassium. A typical label on a plant food will have a set of numbers such as 15-30-15. These numbers mean that the plant food is guaranteed to contain at least 15% nitrogen, 30% phosphorus (expressed as P2O5) and
What do plants need to survive? The answer is simple. There are multiple key factors that are necessary to a plant’s survival. The first is water. No plant can survive without water. There is also the important factor of sunlight. Sunlight gives the plant the necessary energy it needs to undergo photosynthesis. An important factor that nobody else really thinks about is measurement. The right amount of everything is what makes the plant grow high and mighty. Any wrong measurements of materials can cause the plant to die. There is also air. Air is the one thing that no living specimen can survive without. Plants also need space to survive. If the plants get too crowded, then those plants start to compete for resources. Eventually, one plant
This is the most important aspect in a plants life. Ventilation is needed by plants to exchange gases; carbon dioxide is needed by the plant’s stems and leaves for proper photosynthesis, the roots of a plant need oxygen.
The types and growth influences how much nitrogen is captured and released when nitrogen shows higher availability to follow crop. Ii) It improves soil structure when cover crops help open up soil and access to water and nutrient can be improved. Iii) Cover crops supply ground cover for the risk of soil erosion by water or wind, in this case there is possibility of reduction in erosion risk. Iv). Habitat creation which enables cover crops to provide a winter cover and habitat for wild birds, insects and small mammals, and this provides grazing opportunities for wildlife. v) Nutrient losses are reduced – cover crops reduce soil run-off lessen the loss of phosphate fixed to soil particles. This also reduces nitrate leaching and losses of nitrate and nitrate and nitrous oxide. Vi). Weed and pest management – most of cover crops type normally contend with range of weed and assist to provide a clean seedbed for crops. Lastly, water quality are improved and benefited cash crops, this reduces losses of nutrient, sediment and pesticides. It impacts on water quality and habitats when the soil run-off is in high level nutrient and cause choking to other aquatic life.

It is predicted that the removal of plant nutrients in general will result in stunted growth and death of the plant. If phosphurus is removed from a plant, effects will include stunted growth, An abnormal dark green colour, and a reddish-purple pigment excess amounts of sugars. Phosphorus is a component of the complex nucleic acid structure of plants, which regulates protein synthesis. Phosphorus is, therefore, important in cell division and development of new tissue. Phosphorus is also associated with complex energy transformations in the plant. This is why phosphurus deficiency in plants will cause stunted growth. Phosphurus deficent plants will have a dark green colour due to the fact that phosphurus deficiency causes excess biuildup of
As one of the crop with longest history in the world, maize played an important role in feeding human and the animals, as well as is the important raw ingredients for some industrial materials. The production has reached 821 million tons in 2011, mainly cultivated in United States of America, China and Brazil. Both abiotic and biotic factors will affect the growth and development of the maize plant, at the same time influencing also the yield of the crop. Negative interaction between maize plant and other organism is the main biotic driver that is likely to influence the crop productivity. Drought, temperature and solar radiation are biotic factors that can bring greater influence in the crop yield. Soil is also a major driver as it is the nutrient source of the maize plant. One of the main cost factor in cultivation of non-leguminous plant, including maize is the application of fertilisers. In addition, many environmental hazards arise as the
Prior to sowing the trial area was fertilised on the 14th of May with the product, Nitrphoska Perfect at 350kg/ha with a package consisting of: N(15):P(2.2):K(16.6):S(8.1):Mg(1.2):Ca(8)+Trace & Super Phosphate at 220kg/ha P(9.1): S(10.5): Ca(20). The total nutrients of the soil: N (53)*: P (27.7): K (58): S (31): Mg (4.2): Ca (50.3) + Trace had enough available nitrogen to feed the equivalent of a two tonne wheat crop yield. Lupins cultivars were planted at twelve inch spacing’s on the 11th of June. Trial design allowed for a buffer at either end of the plots to not affect the trial itself. For each of the three cultivars the treatments were randomised and were replicated to increase reliability of results (view figure 1). Each of the plot sizes were 1m in length and contained three windrows of each cultivar. Soil tests were taken from each individual cultivar in each plot on the 12th of August to test for nitrate levels. Lupins were then
Nitrogen is the most abundant element found in our atmosphere and it is also the most important for a plant’s growth and one of the elements that a plant intakes in large amounts. “It is one of the basic components of chlorophyll, the compound by which plants use sunlight energy to produce sugars during the process of photosynthesis.” (House & Garden, n.d.) Nitrogen can enter the soil in many ways such as rainfall, which may deposit some atmosphere nitrogen into the soil or some organisms such as, bacteria, actinomycetes and cyanobacteria are known to convert atmospheric nitrogen into ammonium so that plants can absorb easily. High rates of photosynthesis will occur when a plant receives sufficient amounts of nitrogen (N). (CTAHR, n.d)
Within Russia, there are several unmet needs across the nation. One potentially viable product that our organization can introduce is fertilizer for farmers. Fertilizer is a product that may vary from area to area, but contains the necessary nutrients that are needed to add to local soils for the growth of specific agricultural products. This is a significant need within Russia, as the agricultural industry has been falling behind in recent years. It seems that the nation has difficulty producing enough agricultural product to support its needs from year to year. Additionally, farmers do not often use fertilizers to help their crops, which in turn prevents increased productivity. If farmers were educated on the importance of fertilizing
Nitrogen base fertilizers are used around the world and usually contain large amounts of nitrogen. This excess nitrogen is responsible for soil degradation, groundwater pollution emission of ammonia and greenhouse gasses (Geng et al., 2015). The problem lies in being able to produce crops at an effective rate and also being able to reduce the negative effects that nitrogen has in the environment. This paper examines different researches already done on the effect that nitrogen base fertilizers has on crops and the alternatives to the common used fertilizers.
This article investigates the effects of bacterial bio-fertilizers on the growth and yield of rice which is a grain. Bacterial bio-fertilizers investigated in this article include Azatobacter species and pseudomonas species which were isolated from the soil of agricultural crops through employment of plating techniques. This isolation was achieved through selective medium such as Rhizobium medium for rhiobium species, pikovskayas agar for phosphate solubilising microbes and manitol agar for Azatobacter. These bacteria were used to inoculate seeds. After 50 days of growth the physical parameters were measured, they included breadth of leaves, number of leaves, length of shoot, number of flowers, length of root, number of seeds, and number of pods. The result was that all this parameters increased but in different proportions. These findings are directly related to my experiment which invests the effects of Rhiobacteria on plant growth; this article has also used the same parameters I used in my experiment.
