description: On present context, the organic fertilizers have become an important part of farmers, cultivators, gardeners, florists, researchers etc., which has also been economically improved, increased productivity and yield of many plant species. The organic fertilizers are known not only for improving the soil structure by assisting the water retention but also improves the soil texture so that more air is available to the plant rootlets. Like most organisms, plants need a variety of nutrients for their proper growth and development. These nutrients may normally be present in the soil, but the plants may suffer when the nutrients content is either low or altogether absent. Generally, the organic fertilizers were created to make up for the soil deficiencies so that the plants may be grown in less than ideal spaces, however the main nutrients found in the organic fertilizers are nitrogen (N), phosphorus(P), potassium(K). Carbon rich amendments are also a core foundation for healthy soil as it feeds the biological process.Organic Fertilizers, pea, cow manure, poultry manure, vermicompost, seaweed fertilizerPlants also require three nutrients, but in much smaller amounts: Calcium is used by plants in cell membranes, at their growing points and to neutralize toxic materials. In addition, calcium improves soil structure and helps bind organic and inorganic particles together. Magnesium is the only metallic component of chlorophyll. Without it, plants can't process sunlight. Sulphur is a component of many proteins. Finally, there are seven elements that plants need in tiny amounts. Healthy soil that is high in organic matter usually contains adequate amounts of each of these micronutrients: copper iron molybdenum zinc chlorine manganeseAdvantages of using fertilizer: The advantages of using fertilizer in the garden are as follows: Fertilizers can help plants to grow faster. It adds nutritional elements to the soil making the plants healthy with abundant nutrients for plant growth and development. It ensures the fastest growth of plants. Fertilizers also helps eliminate certain soil deficiencies. Fertilizers fulfils the specific needs for a wide range of plants. Fertilizers are known to provide both macro and micro-nutrients. Fertilizers provides essential nutrients that every soil need, including nitrogen, phosphorus, potassium, and magnesium. Disadvantages of using fertilizer: The disadvantages of using fertilizer are as follows: There is a risk of overloading the soil with nutrients when using fertilizer. Certain fertilizers can upset the symbiotic relationship of microbes in the soil. Fertilizers can break the microbial balance in the soil. Certain fertilizers are harmful to the environment as well as the human body. Fertilizers can be more expensive as compared to compost, which can be directly made from food trash, leftover leaves, and kitchen scraps.Some functions of soil organic matters are as follows: Nutrient Supply Organic matter is a reservoir of nutrients that can be released to the soil. Each percent of organic matter in the soil releases 20 to 30 pounds of nitrogen, 4.5 to 6.6 pounds of potassium, and 2 to 3 pounds of sulphur per year. The nutrient release occurs predominantly in the spring and summer, so summer crops benefit more from organic-matter mineralization than winter crops. Water-Holding Capacity Organic matter behaves somewhat like a sponge, with the ability to absorb and hold up to 90 percent of its weight in water. A great advantage of the water-holding capacity of organic matter is that the matter will release most of the water that it absorbs to plants. In contrast, clay holds great quantities of water, but much of it is unavailable to plants. Soil Structure Aggregation Organic matter causes soil to clump and form soil aggregates, which improves soil structure. With better soil structure, permeability (infiltration of water through the soil) improves, in turn improving the soil's ability to take up and hold water. Erosion Prevention This property of organic matter is not widely known. Data used in the universal soil loss equation indicate that increasing soil organic matter from 1 to 3 percent can reduce erosion 20 to 33 percent because of increased water infiltration and stable soil aggregate formation caused by organic matter.AIM OF THE STUDY The main aim of the study was to analyse the different organic fertilizers in pea plant. To study the plant growth, nutritional content, plant yield, height, weight, chlorophyll content grown from different organic fertilizer. To study the N, P, K value content in organic fertilizers and their role. To study the nutritional uptake by plants from organic matters contain in the fertilizers. : SCOPE OF THE STUDY To know the importance of pea plant in ecology and health. To know the desired organic fertilizers for each plant growth. To find out about the role of organic fertilizers in plant growth. To find out the nutritional value of pea plant grown from different organic fertilizers. : LIMITATION OF THE STUDY The study was confined to only one plant i.e., pea plant. The study was conducted in home garden yard within a single area with five different plots of land. The study make use of only four different types of organic fertilizers. The study makes use of ready-made marketed organic fertilizers. Due to limited time and other constraints, the study is based only on general features of pea plants.
