IDENTIFICATION OF FIELD CROPS

IDENTIFICATION OF FIELD CROPS

Identification of crop:

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.
