Before the discovery of oil in Nigeria, the agricultural sector was a major source of foreign exchange. It was also the largest employer of labour in the country. Even now, it remains the largest employment means to Nigerians considering the fact that it is the major source of income in the numerous rural communities.
Note: Regardless of the above fact, Nigeria is still known to import agricultural products like rice, chicken, turkey and fish (as at 2019).
The reasons behind agricultural underproduction in Nigeria is the main point of this article.
Below are some of the agricultural problems in Nigeria:
Mechanized farming is the process of using agricultural machinery on agricultural activities which greatly increases the farm work output.
Nowadays, agricultural machinery has replaced many manual processes and animals such as oxen, horses, donkeys and mules.
Within the rural communities in Nigeria, farmers still utilizes a cutlass for clearing grasses and hoe for digging and making ridges in large farmlands.
The use of the aformentioned crude techniques on large farmlands will greatly slow down agricultural processes and output.
Before now, the government policies on agriculture had been very unfavourable to farmers. This is so because the budgetary allocation to the nation's agricutural sector was quite small. As a result, we saw massive importation and smuggling of various agricultural products.
In 2017, the Nigerian government made policies that encouraged rice production among the different states in Nigeria.
A fertilizer is a chemical or natural substance added to soil or land to increase or improve its fertility.
This cost of fertilizers in Nigeria is quite expensive. As a result, the rural petty farmers are unable to purchase them.
Subsidizing fertilizers and other agricutural materials by the federal and state governments will go a long way in boosting agriculture in Nigeria.
Education is the future of any nation. Unfortunately, the majority of farmers in Nigeria are uneducated and this has lead to poor/reduced agricultural produce.
Improper pest control, use of poor seedlings and poor understanding of plants' physiology are among the attributes of poor agricultural education.
The lack of agricultural storage facilities has lead to the decay of excess agricultural produce in Nigeria.
The quality of various agricultural produce are reduced while others are lost to pest.
Land mode of transportation is the major path to the circulation of agricultural produce within Nigeria.
Understand that road is one of the means of transportation under 'land mode of transportation'.
In addition, the railway system in Nigeria is not significantly developed (as at 2019).
Transportation of agricultural produce is mainly by road in Nigeria. The bad quality of these roads had constantly lead to a decreased amount of produce reaching the market.
Similarly, loss of agricultural produce may also result from accident and theft on these roads.
There are little or no agricultural research centers (agricultural extensions) in Nigeria and as a result, these farmers lack the technical knowhow on how to go about their daily business.
The lack of functioning agricultural research centers in the nation accounts for the underdevelopment and little progress in the agricultural sector.

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.
