Government plays an important role in the development of agriculture. Every government has an annual budget and agriculture happens to be a major sector to which an annual financial allocation is given.
Using the nation Nigeria as a reference, the country once depended almost entirely on agriculture for her external revenue during which the citizens lived like kings at that time. Interestingly, it was reported during that period that the Nigerian currency (Naira) had more value that the Dollar, but right now, the reverse is the case.
It was the discovery of oil in an era called (the oil boom) that brought about negligence of the agricultural sector by the Nigerian Government; as all the focus were placed on oil.
As it stands now, the government of Nigeria must be proactive towards agriculture, education and technology because the era of oil is gradually coming to a decline with the emergence of electric and smart cars/automobiles.
Below are the various ways through which the Government can enhance Agriculture in a Nation.
Knowledge is the key to everything that has been successfully done.
The more education a farmer has, the better his quality and quantity of produce.
Unfortunately, majority of the farmers in Nigeria (and other developing Nations) are from the rural areas; most of which have got little or no education.
The government should set up agricultural schools and institutes in these rural communities in order to increase the quality and quantity agriculture produce.
Education is always the key to a prosperous nation.
The government should provide financial assistance in the form of subsidies, loans and grants to farmers to boost agriculture in each state of a country.
Most of the farmers in developing countries are actually poor because they are neglected by the government; and thus lack the capital to increase their agricultural output. For this reason, majority of these farmers practice subsistence farming.
Subsistence Farming is a type of farming where a farmer grows crop or rear animals for themselves and their families.
Note: Farmers do not farm for financial returns in subsistence farming.
Agro-chemicals are substances or chemicals that are used for increasing agricultural yield and produce when applied to farmland.
Agro-chemicals include fertilizers, herbicides, drugs, fungicides, insecticides, vaccines and so on.
The government should provide agro-chemicals to farmers at a subsidized rate in order to improve agricultural activities.
Storage facilities help to prevent the wastage and spoilage of agriculture produce.
Lack of storage facilities will bring about financial loss to farmers since crops will be destroyed by insect pests.
The government must therefore assist in providing storage facilities in each state of the country.
Bad roads will cause accidents; resulting to the loss of lives and properties.
Without any doubt, some agricultural produce will be damaged and destroyed as a result of bad roads.
Also, a bad road network can elongate the journey of agricultural products from the state where they are produced to another state where they will be sold. To this end, a 24 hour journey might end up becoming 96 hours, thus resulting in the spoilage and wastage of agricultural produce.
It is the government's responsible to provide agricultural machines like tractors, ploughs, harvesters and planters to the large scale farmers. These farm machines may be subsidized to farmers since they can be quite expensive to purchase.
Note: Farm machineries are very important for the cultivation on large farmlands.
High quality seeds and animal species should be provided to farmers.
The availability of high quality seeds and animal species will bring about the following improvements in plants and animals:
Government should provide an efficient quarantine measures to check and control the inflow of agricultural materials like seeds, animals and animal products.
The goal of quarantine measures is to identify and prevent infected agricultural materials from entering into a country.
An adequate quarantine measure will prevent certain disease pathogen from gaining entrance into a country.
It is the responsibility of government to provide agricultural research institutes (which will carry out studies and researches in food and animal breed). The goal is to improve the level of food and animal breed in agriculture.
Some of the research institutes present in Nigeria include:
It is the responsibility of government to establish river basin authorities so as to make water available to farmers especially during dry seasons. This is sometimes referred to as irrigation farming.
Irrigation may be defined as the supply of water to agricultural land or crops through various means and channels in order to enhance plants' growth and development.
The government should set aside a reasonable percentage of the budget to agriculture.
They should also see that the financial allocation to the agricultural ministry is judiciously utilized so that the nation, farmers and citizens will benefit from the agricultural sector.
If the agencies responsible for all the aforementioned government roles in agriculture are corrupt, little or no progress will be seen in the agricultural sector.
The government should set up necessary institutions to punish corrupt officials according to the law.
Also, salaries should be paid to the various agricultural agencies when due.

Amazing facts in Agricultural Science
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 some common types of erosion:
Water Erosion: It is caused by rainfall and flooding on the topsoil. As a result of water erosion, some layers of the topsoil are lost.
Sheet Erosion: When an entire surface of land becomes eroded at a uniform (equal) level, such is referred to as sheet erosion. It is shown below:
Wind Erosion: It results from the actions of wind on a bare land. Wind erosion is often seen in deserts. Overgrazing and lack of vegetation cover will also enhance wind erosion on topsoil.
Soil erosion is defined as a process through which the topsoil is removed or moved from one point to another by agents like wind, water, man and animals.
Soil erosion occurs naturally (wind and water) and may also be facilitated by living organisms.
Soil erosion is more likely to occur on a sloppy land and land with no vegetation cover. When this occurs, the nutrient rich layer of the topsoil is washed away; and this ultimately results in fewer plants growing on such eroded soil.
There are about 630 different kinds of carnivorous plants.
Carnivorous plants are plants that derive some or most of their nutrients by consuming small animals, especially insects.
Carnivorous plants are also referred to as insectivorous plants.
Examples of carnivorous plants include sundew and Venus flytrap.
