CLASSIFICATION.
Classification of Crops
Horticulture is the cultivation of plants within an enclosure, as opposed to field crops.
The botanical method is the most commonly used method of classifying plants.
Taxonomy, the study of plant classification, is dynamic and changes as new knowledge becomes available.
The four divisions of the plant kingdom are Thallophyta, Bryophyta, Pteridophyta, and Spermatophyta.
Spermatophyta is further divided into gymnosperms and angiosperms.
Angiosperms are divided into monocotyledons and dicotyledons.
The binomial system of plant nomenclature was originated by Carl von Linne, also known as Carolus Linnaeus.
Scientific names of plants are written with the genus name capitalized and the species name in lowercase.
Families in plant classification often end with -aceae, but there are exceptions.
Classification of Crops based on Use
Crops can be classified based on their use, such as food, fiber, beverage, oil, or medicinal.
Agronomic crops include cereals, grain legumes, forages, and sugarcane.
Horticultural crops include vegetables, fruits, ornamentals, and plantation crops.
Horticultural crops have more diversity and intensive cultivation compared to agronomic crops.
Horticultural crops have higher aesthetic value and provide important vitamins and minerals.
Agronomic crops are usually processed and eaten in mature stage, while horticultural crops are consumed in fresh form at any stage.
The life cycle of agronomic crops can be semi-annual, annual, or perennial.
Horticultural crops are highly compatible with cropping systems.
Moisture content of harvested horticultural crops is higher compared to agronomic crops.
Examples of Horticultural and Agronomic Crops
Examples of horticultural crops include leafy vegetables, cole/crucifers, root and bulb vegetables, legumes/pulses, solanaceous vegetables, cucurbits, tree fruits, small fruits, herbaceous fruits, oil crops, beverage crops, herbs and spices, fiber crops, plantation crops, medicinal crops, essences/flavoring crops, latex and resin crops, cutflowers, flowering pot plants, foliage plants, ornamentals, bedding plants, landscape plants, and turf grass.
Examples of agronomic crops include cereals, field legumes, fiber crops, drug crops, oil crops, sweeteners, forage and pasture crops, and biofuel crops.

Agriculture-related Information
Special Purpose Classification
Green manure
Crop usually leguminous crops grown for a specific period of time
Plowed under into the soil to improve soil fertility
Example: Mungbean crop planted in the Rice field
Silage
Forage crops harvested, processed, and stored for animal feeds
Soilage
Forage crops cut when green and succulent
Directly fed to livestock
Catch crop
Fast-growing crop grown simultaneously with or between successive plantings of a main crop
Cover crop
Grown primarily to provide ground cover
Improve soil properties
Control erosion
Minimize weeds
Companion crop
Planting one plant in proximity to another
Benefits bestowed on the other crop like insect-repelling qualities
Trap crop
Crop grown to protect the main crop from biotic and abiotic factors
