here is a special article on weeds and their botanical names

here is my post on the botanical names of crop

what is a crop?

A crop is a plant that is grown by man in order to harvest it at some point. The crops grown by the farmer can be classified as follows;
1. According economic uses
2. According to life cycle
3. According to cultivation or tillage practices

1.

Legumes:

these are crops that have nodules or swellings in their roots. They are capable of converting the Nitrogen of the air into plant/crop food. Such crops are very rich in protein. Examples of legumes are, soya beans, cowpea, groundnut, pigeon pea and mucuna.

2.

Cereals:

these are crops that are grown because of their seeds which is used as food by man. Such crops are very rich in carbohydrate. Examples of Cereal Crops are Rice, Maize, Guinea corn (sorghum), Millet and Wheat.

3.

Roots and Tubers:

these are crops that store food in their roots. They are very rich in carbohydrate. They form the staple food for most people in Nigeria and sub-Sahara Africa. Examples are Cassava, potato, yam and Carrot.

4.
Vegetables:
these are crops whose leaves and fruits are used as vegetables
in foods. Such crops are rich in vitamins needed by the body. Examples are tomato, onion, fluted pumpkin, okra, lettuce, cabbage and green vegetable.

5.
Fruit crops
these are crops that are grown for their fruits which supply vitamin and sugars to the body. Examples are mango, pineapple, orange, pawpaw, banana, cashew etc

6.
Beverage crops:
A beverage crop is the one that produces a potable beverage other than water. It can also include crops that produce starch (all cereals) or sugar (sugarcane, sugar beet), which can be used for making a drink or a beverage.







Beverage is a potable drink other than water. The word beverage was COINED from the old French word boivre or ‘boire’ that means a drink. There are two types of beverages: non-alcoholic and alcoholic. Common non-alcoholic beverages include coffee, tea, milk, coke, sodas, etc. Alcoholic beverages include beers, wine, whiskey, and other hard drinks.

The common non-alcoholic beverage crops are coffee, tea, sugarcane, sugar beet, coconut, lemon grass, etc.

CLASSIFICATION OF CROPS ACCORDING TO THEIR LIFE CYCLE


On the bases of life cycle, crops are grouped into three sets.

These are:
(a) Annual Crops
(b) Biennial Crops
(c) Perennial Crops


YOU CAN ALSO READ ABOUT THE CLASSIFICATION OF FRUITS IN THIS POST
(a)

Annual Crops:

These are crops that complete their life cycle in one year or planting season. The crops are planted, grow and are harvested or will die within one year. This group of crops are Maize, Rice, Millet, Yam, Tomato, Millet and Guinea Corn

(b)

Biennial Crops:

these are crops that complete their life cycle in two years. They use the first year to grow and store food. Reproduction and maturity takes place in the second year. Examples are pineapple, cocoyam, plantain, banana and sugar beet.

(c)

Perennial Crops:

this group of crop takes more than two years to their life cycle. They are mainly tree crops. They include Rubber, Cocoa, Oil Palm and Orange.

3.

CLASSIFICATION OF CROPS BASED ON THEIR TILLAGE PRACTICES


TILLAGE OR CULTIVATION PRACTICES HERE

On the bases of tillage practices, crops are classified into:

(a) arable crops
(b) Non-arable crops



(a)

Arable crops:

these set of crops are also called food crops. Most of them are planted and harvested within one year. The cultivation of arable crops most cases involve total tillage of the soil before planting. The crops includes maize, rice, millet, cassava and guinea corn

(b)

Non-arable crop:

these sets of crops most often does not require total tillage of the ground except the very spot where the plant will be established. They are orange, guava, oil palm, cashew, cocoa, etc. they are often called cash crops.

Cultivation of crops according to the number of seed-leaf or cotyledon Crops can be classified according to the number of seed leaf or cotyledon.

They are
(a) Monocotyledonous crops
(b) Dicotyledonous crops

(a)

Monocotyledonous crops:

these are crops that have only one seed leaf or cotyledon. Examples are millet, rice, maize and oil palm.

(b)

Dicotyledonous crops:


these are crops that have two seed leaves or cotyledon. Examples are cow-pea, melon, mango, pumpkin and soya beans.

Vegetation zones of Nigeria



Map of Nigeria showing the different Vegetation Zones


KEY


Sahel Savanna


Sudan Savanna


Guinea Savanna


Rain Forest



Mangrove and Fresh Water Swamp Forest



1. Mangrove and fresh water swamp forest


This occupies the delta part of Nigeria with heavy rainfall of up to 200 cm and more per annum.

The major activities in this region include lumbering (felling of timbers) and fishing.


Swamp rice can also be grown in the area.


2. Rain forest This occurs in the Southern part of Nigeria lying above the mangrove and fresh water Swamp Forest. The annual rainfall of this one is about 150 cm to 200 cm.


This region consists of tall woody trees and strong undergrowth. Examples of trees found here include iroko, obeche, opepe, mahogany, afara, etc.

There is a high degree of farming activity in this region. Crops commonly grown are yam, coco yam, cassava, maize, rice, plantain, Cocoa, rubber, oil palm, kola, mango, citrus, etc.


Animals include dwarf goat, sheep, pigs, cattle and poultry. Fish ponds are also kept. Guinea savanna This zone is cutting deep into the rain forest due to continued cultivation.







Such areas are now referred to as derived savanna. The Guinea Savanna area is made up of tall strong grasses Interspersed with trees of moderate heights. Annual rainfall is about 100cm to 150cm.

This zone is the largest vegetation zone in Nigeria. It is an area of intensive agricultural activity. Crops grown include all cereals, legumes such as cow-peas and groundnuts, cotton, yam,
cassava and potatoes Livestock include
cattle, goat,

sheep,
poultry and others.


4. Sudan savanna This zone is covered with more grasses and short scattered trees and has an annual rainfall of 50 cm to 75 cm. Agricultural activity in this area centres mainly on cattle, sheep and goat rearing. Poultry is also kept while donkeys, camels and horses are equally reared.


HERE IS MY POST ON FORESTRY AND RESERVES

Crops grown are mainly sugar cane, millet and sorghum.

Vegetables particularly carrot and tomatoes
are grown along river beds, streams and in areas with irrigation facilities.


5. Sahel savanna This occupies the extreme north-east of Nigeria with an annual rainfall of about 15 cm to 50 cm.


It is characterized by feathery grasses and highly scattered spiny shrubs (thorn bushes).

Animals are mostly reared here during the rainy season while drought' resistant crops like dwarf sorghum and millet are cultivated.r

FACTORS AFFECTING THE DISTRIBUTION OF CROPS

1. WATER
2. SUN SHINE
3. TYPE OF SOIL AND
4. ACTION OF MAN


Crops and their bye-products are used in the following ways:

1. They used as food by man.
2. Planks from timber are used for making shelters.
3. Clothing: son many of the clothing materials are made from crop material such as cotton
4. Used for feeding farm animals
5. For the control of erosion such as planting of cover crops
6. For making books and papers
7. For making furniture
8. Used for the production of medicine or drugs
9. Some crop serves as beverage
10. Some dead crop materials are used as fuel
11. Used for making compost manure
12. Some are used in the industries for the production of gums, rubber wares and perfume
