The term “ Agriculture” has been derived from two latin words ‘ ager ‘ meaning land or field and
‘ cultura ’ meaning cultivation. Therefore literary meaning of Agriculture is the cultivation of land or field. But in the real sense, Agriculture is the science and art which deals with the production, improvement, protection. processing, marketing and extension of crops, livestock and fishes by the proper utilization of natural resources (i.e. land, light, air, temperature, water, humidity etc.) for the benefit of mankind.
Agronomy :
The word “agronomy” is derived from two Greek words ‘agros’ meaning field and ‘namos’ meaning management. Therefore literary meaning of Agronomy is the management of field. Agronomy is the branch of Agricultural science which deals with the production of field crops through proper management of soil, without deteriorating soil fertility.
In these days of specialization and under continuous advancement of agricultural science “ Agronomy “ may be defined as the branch of agricultural science which deals with manipulation and / or exploitation of basis ingredients of agriculture- seed, soil, water and environment to suit crop production under particular agro-climatic & agro-ecological condition and tailoring, reshaping and finally assembling the component of crop production technologies developed by Agronomists and non-agronomists into packages of practices acceptable by the farming community.
For, viva
Agronomy is the culture of land for the production of field crops by the proper utilization of natural resources. (land, light, air, water).

Origin and History of Agriculture
“Agriculture is the root of culture”
Origin and History :
As stated by henry Feber:
“History celebrates battles in a bright way but is quite silent about the origin of agriculture which is the backbone of a nation.” So, it cannot be said with certainty when and where the first man put the land under the plough / cultivation.
However, agriculture is as old as the advance of human life. Records tell us that the agriculture was first taken up by the inhabitants of central Asia from where it traveled to Mediterranean countries like Egypt, Italy, and Greece and to India and the rest of the world.
The present status of agriculture has come through the evolutionary pathway of different distinct phases, those are given follows:-
1. Root grabbing stage / Primary / Primitive
2. Hunting stage
3. Fire and Iron weapon stage
4. Pastoral stage or Animal husbandry / Domestication
5. Crop husbandry or Agricultural stage.
1. Root Grabbing Stage :
This was the stage when man was living a primitive animal like existence. There was no knowledge of agriculture, but people fed on raw materials such as roots, berries, wildfruits and herbs etc.
2. Hunting Stage :
In this stage people started to use weapons like sticks, bones of animals, pieces of stones for hunting wild animals for food. They used to take raw meat in addition to roots etc.
3. Fire and Iron Weapon Stage :
The discovery of fire enabled the production of refined types of weapon from iron for hunting. In this stage roosted meat was taken instead of raw.
4. Pastoral Stage or Animal Husbandry:
In this stage the people did not start actual crop cultivation but started domesticating animals such as sheep and cattle (which is considered as a branch of agriculture). At first, animals to be domesticated were dogs and horses.
These were used mainly for guarding and hunting purposes. They started loading a nomadic style of life because they needed to move from one place to other in search of feeding materials i.e. pasture for their animals.
5. Crop Husbandry or Agricultural Stage :
At this stage people were discontented with nomadic life. They started settling at those places near rivers where irrigation facilities were available and started raising crops and domestic livestock. From this time, the crop husbandry or agricultural stage started as we know it.
Prior to the application of science, agriculture was purely carried out in the light of experience received from previous generations or from neighbor and this side of the picture is known as the art side of agriculture. Agriculture is thus an applied science which is hardly one century old.

Fig: Schematic presentation of branches of Agriculture.
A plant that is grown with proper care and management for its economic value, is termed as crop.
It is very difficult to give a precise definition of crop but it has some characteristics-
i. Crop must be cultivated species.
ii. It must have economic value.
Crop is an aggregation of individual plants, grown on a particular location usually of the same species or variety and has same economic value.
Agronomic crops or field crop:
The crop, which are grown together with less care, usually in large areas and harvested in bulk, is termed as agronomic crops.
Horticultural crops:
Crops that is grown with intensive care.
Definition of identification:
Identification is the art or technique by which one can differentiate various objects or organism (plants, animals) from each other considering their typical characteristics (morphology) and functions.
Identification of Crop:
Identification of crop is an art through which unwanted plants can be separated out from the cropped area. Crops of different species are also separated out on basis of their morphological features.
Importance of identification of crops:
Unwanted plants in crop field often results in severe competition for space, light, nutrients etc. and the quality of the produce is impaired. So, crops and non-crop species should be identified for successful crop production and better yield.
Classification of crops:
Classification is an acceptable product of scientific studies and is obviously based on well-defined characteristics or concepts that separate one group from another.
On the basis of use of crop plants and their products, crop can be classified as follows-
Cereal crops:
Cereals are the cultivated grasses grown for their edible starchy grains under graminae family.
