What Is Plant Productivity?
The productivity of a plant is the ability of plant to yield. It is measured by the amount of yield it gives per unit area. It is also expressed as kg or ton/ha or ton/acre or bushel/acre. The productivity is directly proportional to the amount of food and fiber produced and hence indirectly proportional to the well being and standard of living of the people. Other factors like disease, weather conditions and soil fertility also affect the food productivity..
Why is plant productivity important?
Plants are the foundation of life on Earth. 75% of all the oxygen on Earth comes directly from plants. Plants are the only organisms on Earth that are capable of performing photosynthesis. Plants are also critical to the global carbon cycle. Carbon is transferred between the atmosphere, the oceans, the land, and living organisms. Plants are also important to the health of our soil. Plants give life, so it is vital that we use our knowledge of plants to ensure that they remain healthy and productive..
What do you mean by plant productivity?
Plant productivity is the total amount of output that can be produced by a plant in a particular time period. It is the output produced for a given input of energy, materials and labor. It refers to the amount of output, per unit time, compared with the amount of input. It can be considered as the inverse of productivity, which is the efficiency of the plant. Plant productivity is calculated by dividing the amount of output produced by the amount of input (such as labor, energy, materials, etc.) used to produce the output. For example, if a plant takes 20 units of labor time, 50 units of material and 1000 units of energy to produce 1000 units of output, then the productivity is 1000 units of output divided by 20 units of labor time (or labor productivity is 500 units of output per labor unit). The labor productivity is calculated by dividing 1000 units by 20 units, which equals 50 units per labor time..
How can plant productivity be improved?
Plant productivity is the value of the crop produced in a unit of land over a period of time. To find the answers to the question, you have to analyze the factors that affects plant productivity. These factors are soil, plant, environment, crop management, farm management, marketing, and others. Soil quality is one of the most important factors in determining plant productivity. The productivity of crops declines in low-fertility soils. Soil fertility is the ability of the soil to support plant growth. So, when it comes to increase plant productivity, the main factor that is to be taken into consideration is the soil. This is because, the health of the plant is directly proportional to the health of the soil. Besides, the soil fertility is one of the main factor to increase plant productivity. So, in order to increase crop productivity, the soil fertility should be improved. One of the most significant means to improve soil quality or fertility is by the use of organic matter. The organic matter directly improves the structure of the soil..
How do you calculate plant productivity?
Plant productivity (PP) is a measurement of production of a plant, and is calculated as: PP = M / Q in which M is the weight in grams of plant material grown in unit time, in this case kilograms per day, and in Q in kilogram per hectare in which the unit is hectare per day (kg/ha/day). We can find out the weight of the plant produced in kilogram by dividing the weight of the plant by the number of days the plant was grown, for example 30g / 10 days, which is 3kg/10 days, which is 300g/day. 29.1Btls of natural gas per day produced by Reliance is converted to 29.1Mmscmd by multiplying it by 12500m3/Btls, which is equal to 29.1Btls * 12500m3/Btls = 357.5Mm3/day. Then, 300g/day is multiplied by 357.5Mm3 per day, which is equal to 102.5 Mm3 of natural gas per day. So, the energy released per unit time, in this case day per day, is 102.5. 102.5 is then divided by 357.5, which is equal to 0.27, which is 27%..
What is the difference between productivity and biodiversity?
Productivity : To understand the productivity of an ecosystem, we need to understand the concept of productivity itself. Productivity is defined as the amount of useful material (inorganic or organic matter) that is incorporated into biomass (living) in a given period of time. It is important to remember that productivity does not measure the amount of biomass that is formed in an ecosystem, but rather the amount of biomass that is incorporated into the existing biomass of the system. Biomass is always in flux in an ecosystem. Sometimes it is made up of living organisms, sometimes not living..
How are diversity and productivity related?
Providing an environment of inclusion and diversity will not only bring productivity but also increase your revenue. There are many interests, preferences, and cultures of people around you. And you need different kinds of people to build a better work environment. It is not just about maintaining social harmony, but also about making timely decisions. All of your executives will have different views about the work. So, you shouldn’t make rash decisions without discussing the matter with your executives. It will increase job satisfaction among your employees. And it will make them productive..
What is productivity in biology class 12?
Productivity is the relationship that exists between two given variables: production and efficiency. Productivity is the output of a certain process per unit of input. In simple words, productivity is the ratio of output to input. Productivity distance/production/efficiency. Productivity is the degree of efficiency of production. Productivity is the effectiveness of output. Productivity is the efficiency of production. Productivity is the ratio of output to input. Productivity is the ratio of actual to potential output. Productivity is the ratio of output to input. Productivity is the effectiveness of output..
Which ecosystem is most productive?
According to this study , which puts numbers on the other answers here, the most productive ecosystem is Silicon Valley, followed by New York City. The least productive ecosystems are India, then China, then Russia..
What is primary productivity example?
The Primary Productivity Model, developed by marine ecologist Howard Odum, has been developed to measure the productivity of a system. It is a relatively simple model to understand and can be applied to a wide variety of systems, from a pond to an ecosystem. The model contains three basic components: a pump, a store and a leak. The pump represents the energy flow into a system, the store represents the storage of energy within a system, and the leak represents the energy that leaves a system. Energy that leaves a system is essentially unavailable or unusable energy. Energy from the Sun that reaches the Earth is the primary pump for the global ecosystem, providing the energy needed for primary productivity. Energy from the primary pump is absorbed by plants. Energy from plants is stored in the primary store, which is the plant biomass. Energy from the primary store is released when plants are eaten or die and become available to other organisms. Energy from organisms dying and being eaten is the primary leak. Energy from the primary leak is not available for primary productivity, which is the basis of all ecosystems..

What is NPP and GPP?
NPP is Net Promoter Score. It is one type of customer loyalty metric used by businesses to measure their customer satisfaction. NPS is calculated by asking the customers only one question, “On a scale of zero to ten, how likely are you to recommend our product/company to your friends/family/colleagues?”.
What is NPP and how is it calculated?
__National Productivity Performance (NPP) is a nation’s efficiency in producing goods and services. It is calculated by dividing GDP by total employee compensation. NPP is a good indicator for country’s wealth. Higher the NPP, better is the efficiency of work force. Economists use NPP as one of the measures of competitiveness of a country. NPP also helps to study the productivity of employees. GDP represents the total dollar value of all finished goods and services produced within the country’s border in a particular time period. GDP is usually measured in dollar..
How do you measure primary productivity in plants?
Primary productivity is the rate at which biomass is produced by a given plant community. It is expressed as the amount of biomass produced per unit area per unit time. Primary productivity is often called net primary productivity as it is the net result of the net conversion of solar energy to biomass. If all biomass is harvested, the net primary productivity is equal to the gross primary productivity. Primary productivity is an important part of the carbon cycle..
