This is a type of agriculture that focuses on growing crops like cereals (e.g wheat, maize, rice), legumes (e.g beans, lentils groundnut), fibers (e.g cotton, jute), root and tubers (e.g potatoes and yams) on the field through systematic land preparation and crop rotation for consistent yields.
Arable farming include practices like monocropping, mixed cropping, interplanting, continuous cropping, multiple croppling, crop rotation and taungya farming.
Please read on the types of agriculture: subsistence and commercial agriculture here.
Mono cropping, also termed as sole cropping, is defined as the growing of only one type of crop on a piece of land at a given time. Such crop may be an annual, a biennial or perennial crop.
Note: Annual crops complete their life cycle within one year, e.g rice maize and millet. Biennial crops complete the life cycle between one and two years, e.g carrots, onions and cabbage. Perennial crops complete their life cycle after two years. Examples are cocoa, rubber and mango trees.
Please read on the differences between plants and crops here.
.
Monocropping encourages specialization.
It is easy to mechanize crop production. Please read on agricultural machines and their uses here.
The farm is easier to manage.
Weeds, pests and disease can be controlled.
It reduces complexity, making decisions about soil preparation, fertilization, and pest control consistent across the entire farm. Please read on classification of insect pest and their economic importance here.
It increases efficiency and lowers cost.
It reduce the need for diverse labor and specialized skills.
It maximizes output and income by focusing on a single, profitable crop suited to the environment.
Please read on ranching, its advantages and disadvantages here.
It encourages the buildup of pests and disease on the farm.
It poses risk, especially when there is an outbreak or epidermic of pests, diseases, flood or drought. Please read on the ways to prevent soil erosion here.
Overproduction may result to a drop in the market price of agricultural produce.
It can be expensive to manage since fertilizers and agricultural machines may be purchased. Please read on commercial agriculture here.
There is decline in yield.
There is lack of variety of food crops produced by the farmers.
It exposes the land to erosion after harvest.
It brings about soil degradation by depleting specific nutrients, while also reducing beneficial microorganisms, ultimately leading to damage of soil structure. Please read on sandy soil and how to make it fertile here.
It can lead to lower water retention by the soil, and consequently, soil erosion.
Heavy use of synthetic fertilizers and pesticides contaminates water and air, harming the community in the process Please read on air pollution and its effects here.
It eliminate habitats for pollinators, beneficial insects, and wildlife.
A single crop failure (due to weather, pests, or market changes) can drastically reduce the farmer's income, as there are no other crops to fall back on.

Amazing facts in Agricultural Science
Cows technically have one stomach, not four. However, a cow's stomach has four compartments. These are: rumen, reticulum, omasum and abomasum
Peanuts are legumes and not nuts
Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments
Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them
Cows have got the ability to walk up stairs, but not down stairs
A group of cows is called a team, drove or herd.
People just prefer to call them herd
Notable points in Agricultural Science
Below are characteristics of gymnosperms:
Their seeds have cones that protect them.
Sepals and petals aren't present in their cones.
Stigma and style are absent.
They do not produce fruits. Only seeds are formed.
Companion cells are absent.
Sporophyll form the cones.
Anther and filament are absent.
The ovules are not present in the ovary.
Gymnosperms do not possess flowers.
Please read on the anatomical differences between gymnosperms and angiosperms here
The flower is the reproductive organ in plants' sexual reproduction. In order to achieve a successful sexual propagation or reproduction in plants, the floral parts of the flower are utilized.
The floral parts of a flower consists of the followings:
Sepals
Petals
Stamen
Carpel
The stamen is male portion of a plant. It consists of the anther and filament.
The carpel (or pistil) is the female portion of the plant. It consists of the stigma, style and ovary.
An organism will be considered a pest if it does one of the followings:
Attack crops and eat its seeds, roots, stem, leaves and flowers. Examples are locust and grasshoppers.
Cause damage to stored food, fruits or other agricultural produce. Some may even urinate or deaficate on these products. Examples are rodents, cockroaches and mice.
Attack and kill farm animals like goats, sheep and cattle. Examples are foxes, wild cats and snakes.
Act as disease vectors. A vector is an organism that carries parasite and other disease causing organisms, without being affected; but when they introduce the parasites into their host, such host becomes infected with disease. Examples of vectors are rodents and mosquitoes.
Below are the classification of crops based on their uses:
Oil crops
Vegetable crops
Latex crops
Drug and Medicinal crops
Beverage crops
Fibre crops
Fruit crops
Root and Tubers
Legumes
Spices
Cereals
All crops are plants but not all plants are crops. Below are some instances:
Weeds are considered as plants, not crops.
Parasitic plants are not necessarily crops. Examples of parasitic plants include mistletoe, corpse flower and striga.
Carnivorous or insectivorous plants are not necessarily crops. Examples are sundew, venus flytrap and pitcher plant. The image below shows a carnivorous plant (venus flytrap).
Meanwhile, always understand that all crops are plants, and they are grown for food, money or something beneficial.
