Agricultural science as a subject comes with a variety of technical terms. Understanding the definitions and meanings of various agricutural terms will make this subject easier and comprehensible for you.
In this article, we will look at the various Agricutural terms and the meanings for the alphabet "A".
Below are the various agricutural term (Letter "A"):
This is the premature termination of the developing pollen grains, ova, gametes, embryos, seeds, fruits, flowers and other growing parts of a plant.
A soil is considered to be acidic when it's pH value is less than 7.0.
Note: pH is the degree of acidity or alkalinity of a medium. It is written as "a small letter p" and "a capital letter H".
This is an erosion that occurs at a faster rate than the normal erosion, natural erosion and geologic erosion; and it occurs mainly from man's activity, animal's activity or natural catastrophes' that exposes the bare surfaces of the soil.
Note: Recall that erosion is the removal of the soil's top layer
An acre is a parcel of land with the size of: 4,840 square yards or 43,560 square feet.
These are intercellular or gaseous spaces that are present in the cortical tissues of aquatic plants' leaves, stems and root.
Gaseous exchanges in aquatic plants are facilitated via the aerenchyma.
Afforestation is the planting of trees (or tree crop) on an area of land with few or no trees.
This is a period of dormancy that occurs after the formation of seed in a fruit; and is important for the changes that ensures the germination of embryo.
The plant's embryo is present inside the seed.
This is a business that earns its revenue from Agricutural activities.
Agriculture is a science that deals with plant and animal farming; including the cultivation of the soil for the purpose of growing crops and rearing animals to provide food for man and animals, raw materials for industries and other agricutural products.
This is the science of using living organisms, cells or other cell constituents to develop agriculture and agricultural products.
This is the science that involves the design of agricultural machinery and equipment, which are useful for the various agricutural operations.
Agricutural machineries produced from Agricutural Engineering includes harvesters, ploughing machines and tractors.
These are cooperative bodies that work with the Federal and State agencies to carry out research and education for rural and urban producer and consumer groups; through their specialist personnel for each particular area of the state or country.
The science of crop production and soil management.
A leguminous crop used for forage or hay in livestock.
A pesticide used for controlling/killing algae.
Note: Algae are usually present in lakes, canals, damp walls, swimming pools, water tanks and other water related bodies.
A soil is considered to be alkaline when it's pH value is greater than 7.0.
This is a cropping system that involves the growing of closely planted trees or shrubs between lines (usually 6 meters in width).
The crops grown in alley cropping are frequently pruned in order to provide nutrients to the crops in the alley.
This is a farming method that employs the use of non-chemical intensive farming practice.
An instance of alternative farming is seen when a farmer uses animal and green manure as fertilizer rather that using the usual chemical intensive fertilizer like NPK.
Another instance is where a farmer controls pest by using biological systems (that is; through animals) rather than the chemical intensive pesticides.
These are carcasses of farm animals (poultry or livestock) that can be processed by cooking, drying, curing, roasting or another method.
This is a unit of measurement of livestock; with the equivalent of one mature cow weighing 1,000 lbs.
The Animal Unit (measurement) is used in making comparisons of feed consumption.
Note: Five mature ewes a also are considered an animal unit.
This is a plant that completes its life cycle from seed to plant, flower, and new seed in 1 year or less.
These are domesticated colonies of bees in hives and other beekeeping equipment for the purpose of producing honey.
This refers to the cultivation of aquatic plants for the purpose of food, drugs or something beneficial to man.
These are plants that live in water.
Aquatic Plants grow in water either by floating on its surface, partially embedding its roots and stem in the water or growing under the surface of the water.
This is a barren land or a desert or a semi-desert characterised by its dryness and very low annual rainfall.
This is the mechanical injection of male semen into the womb of the female with a special syringe-like apparatus.
Note: Artificial Insemination is used extensively in dairy husbandry.
These are organisms that can produce organic matter (food) from inorganic substances.
Note: Plants are photosynthetic autotrophs that manufacture their food through sunlight energy trapped by the chlorophyll present in the chloroplast of the leaves. The process involved is termed photosynthesis
This is a spiral device on a shaft that's used to move grain through a tube.
They are plants' growth hormones (natural or synthetic).Auxins regulates plants' growth and development.
They are related to birds (poultry and/or fowl, Guinea fowl and turkey).
