Week 1 & 2
Topic: Storage of Farm Produce
Introduction
After harvesting, farm products are subject to attack by insect pests and microorganisms if they are not properly kept. To reduce the incidence of pests and to avoid spoilage, agricultural products are kept in special places either for long or short periods depending on when they are sent to the market or used as input during the next planting season. The process of effectively keeping away pests and microorganisms from harvested agricultural products to avoid spoilage is called storage. To learn more, Click here
Week 3
Topic: Crop Plant Diseases
Generally, the disease can be defined as an infection or unfavourable condition caused by living organisms (pathogens) or non-living things expressed in characteristic conditions known as symptoms and harmful to the organism or its parts or it may simply reduce the market value.
Plant Disease
A plant disease may be defined as a departure or deviation of the plant from the normal state of health, presenting marked symptoms or outward visible signs. In other words, the disease is an unfavourable condition caused either by the pathogens present within a living organism or by nutritional deficiency. It usually results in physiological and anatomical abnormalities expressed in characteristic symptoms. The harmful effects of the disease on the plant or on any of its parts and products generally result in the reduction of the economic value of the plant. To learn more, Click here
Week 4
Topic: Development of Agriculture in Nigeria
The Historical Development of Agriculture
The early man was a hunter, in the quest of securing food, the early man moved from place to place hunting and gathering wild animals and fruits.

Also, he found out that some young animals were hunted and taken to their camp mate with the female kinds and produce offspring then he decided to spare some of the heal of their animals and rare them.
Instead of the hoes and machetes made out of sticks and stones and ploughs drawn by animals and hoes and machetes are now constructed with metals and wood, ploughs are operated manually. To learn more, Click here

Week 6
Topic: Forest and Forest Uses
Forest
A forest can be defined as an area of land set aside for the production of timber and other forest products. It consists of a group of trees and a community of many other living organisms including animals. Forest can be defined as a large area of land covered with trees and bushes, either growing wild or planted for some purposes. A forest is a large area dominated by trees. The forest is a complex ecosystem consisting mainly of trees that buffer the earth and support a myriad of life forms. The trees help create a special environment which, in turn, affects the kinds of animals and plants that can exist in the forest. Trees are an important component of the environment. They clean the air, cool it on hot days, conserve heat at night, and act as excellent sound absorbers. To learn more, Click here
Week 7
Topic: Farm Animal Diseases (I)
Diseases
Diseases can be defined as the absence of normal health due to infection, nutritional deficiency and imbalance, hereditary and functional disorders as well as injuries. Diseases can also be described as any disturbance in the normal life or body function of an organism which may affect a particular organ or the whole body and sometimes leads to reduced growth, production or premature death.
Infectious Diseases – these are diseases which can affect an animal without the animal coming in contact with the infected animal. Transmission of this type of disease is through air, water, dust. Examples are fowl cholera, anthrax, and tuberculosis.
Contagious Diseases – A disease is said to be contagious if the mode of transmission is by a healthy animal coming in physical contact with an infected animal with the diseases being transferred. Examples of such diseases are Foot and Mouth Disease, and Newcastle disease. To learn more, Click here

Week 9
Topic: Preservation of Farm Produce for Marketing
Introduction
One of the greatest problems facing most Nigerian farmers is how to preserve their farm produce after harvesting. Most of the farm produce whether livestock or crops is perishable. To reduce wastage due to spoilage, farmers employ different methods to preserve their products until they are consumed or sent to the market for sale.
Preservation of farm produce is one of the greatest problems facing farmers in Nigeria. This is so because of the nature of farm produce (livestock or crops) which is their high perishability. They are highly perishable because of their high moisture content which in turn promotes the activities of microorganisms which bring about spoilage. The needs for preservation of the farm produce are to reduce wastage due to spoilage until such products are consumed or sent to the market for sale. Preservation can be defined as, the process of keeping farm produce from decay and spoilage (by maintaining the quality) until they are consumed or sold. To learn more, Click here
