of Agriculture
.
Agriculture involves more than just
planting of crops and rearing of animals. It is broad in scope. It is made up
of many branches of science. The study of agriculture involves the biology of
plants and animals, the Chemistry and Physics of soils, mathematics and other
areas. Hence, the study of agriculture as a subject is regarded as agricultural
science.
The
scope and branches of agriculture
includes Basic
agriculture, Animal science, soil, crop science, Horticulture, fishery,
forestry, Agricultural Economics, Agricultural Extension, Veterinary machine
and Agricultural Engineering.
 Basic
agriculture/agricultural education
deals
with the study of agricultural science as a subject i.e the teaching of
agriculture in schools. A specialist in this area is called agricultural
science teacher/lecturer.
Animal science deals with the study of the various farm animals. A specialist in
this area is called animal scientist.
Soil science
deals with the study of the types of soils. A specialist in this area is called
a soil scientist .
Crop science
deals with the study of the various type of crops that are cultivated farmers.

EVALUATION:
       
Why is agriculture regarded as a
science subject?
       
List eight branches of agriculture.
Sub-Topic 2: FORMS OF AGRICULTURE
A.Crop farming: It involves the production of different types of
crops. They are mostly used as food for man, feed for animals and raw materials
for industries Examples of such crops(annual) include maize, rice, mille,
sorghum, yam, potatoes, pepper, Soya-bean, groundnut, tomatoes, okra, etc.
Other farmers practice the growing
of perennial or permanent crops such as cocoa, oil palm, coffee, rubber,
citrus, cashew, kola, guava, mango etc which are also known as cash crops. The
system of cropping on a piece of land varies from one place to another and from
one farmer to the other. Those who engage in commercial farming for profit
making often adopt mono-cropping system (i.e. growing of only one type of crop
on the same piece of land at the same time), while most local farmers prefer
the growing of different crops on the same piece of land (mixed cropping).
B. Horticulture (Ornamental Plants)
Horticulture is a form of
agriculture, which deals with the growing of different kinds of vegetables,
fruits and ornamental plants. The vegetable crops include , okra,  tomato, pumpkin, cabbage, cucumber, egg
plant, water leaves, spinach, bitter leaves, amaranthus etc. Examples of fruits
include  cashew, citrus, mango, avocado
pear, banana, pawpaw, apple, guava  etc,
while ornamental crops are commonly grown for the beautification of the
environment .They include pride of Barbados, hibiscus, croton, zinnia, ixora,
queen of the night, and rose flowers, etc
vegetables and fruits are source of
minerals and vitamins to human bodies, ornamental plants are very useful for
landscaping , attractive parks, gardens, buildings, place of worship, hotels,
streets, etc.
