Introduction and Fundamentals of Horticulture: Branches, Importance and Scope

Etymology/Term derived from

The term “Horticulture” is derived from the Latin word “Hortus”, meaning garden and “Cultura”, meaning cultivation.

History of Horticulture

The term “Horticulture” first appeared in written language in the 17th century and was mentioned in Peter Lauremberg’s treatise/work in 1631.

In English, the term “Horticulture” was first mentioned by Edward Phillips in the “New World of English Words,” London, 1678.

The beginning of horticulture as a science can be traced to the founding of the Horticultural Society of London, England, in 1806, which subsequently became the Royal Horticultural Society (RHS) (Fletcher, 1989).

The international Society for horticultural Science (ISHS) derived from a series of international Horticultural Congresses that began in 1864 in Brussels, Belgium.

What is Horticulture

Horticulture is a part of agriculture which is concerned with the cultivation of “Garden crops”. Garden crops traditionally include fruits, vegetables, ornamental plants, spices, plantation crops, medicinal and aromatics crops.

Also some other definition of horticulture

• Horticulture can be defined as the branch of agriculture concerned with intensive cultivation of plants directly used by people for food, medicinal purpose or aesthetic gratifications.
• Horticulture can be very broadly defined as the science that deals with the production, utilization and improvement of fruits, vegetables, ornamentals, spices and condiments, medicinal and aromatic crops, and plantation crops, as well as gardening, protected cultivation and value addition.

Horticulture as a Science

In addition to agriculture, horticulture involves the application of physics, chemistry and other fundamental sciences, as well as plant sciences such as biochemistry, plant physiology, botany, genetics and plant breeding.

Horticulture as an Art

Horticulture is also an artistic application of technical knowledge. For example, raising flowering plants in small pots, budding roses with different colors, prunning trees into different shapes, designing gardens, and growing flowers with matching colors according to the season.

 

Branches/Divisions of Horticulture

A.     Pomology

The term “Pomology” is derived from Latin word “pomum” meaning fruit and the Greek word “logy” meaning science.

Pomology is the science of production of fruit crops.

Fruits crops are classified as woody plant and herbaceous plants. Woody plants may be trees, shrubs or vines and may be deciduous and evergreen. Deciduous plants are those which have a distinct rest period during which all growth activities stop. They normally shed their leaves before entering the rest period. This period of inactivity generally coincides with winter. After the rest period, at the end of winter, they produce new growth and flowers.

Based on temperature requirements, fruit crops are classified into temperate, sub-tropical and tropical fruits.

Evergreen plants do not have any distinct rest period. They retain leaves always, but in such plants, there may be a period of comparative inactivity. The plant will not shed their leaves during this period. This period of comparatively inactive generally occurs just before flowering.

B.      Olericulture

The term “Olericulture” is derived from the Latin word “oleris” meaning pot herbs and the English word, “culture” meaning raising of crops. Thus, olericulture is the science of production of vegetable crops.

In horticultural science, vegetables are edible herbaceous plants or plant parts commonly used for culinary purposes or as salads.

It includes vegetable production technology, nursery production, genetics and breeding, molecular breeding, plant genetic resources (PGR), seed production, vegetable seed industry, cropping systems, storage, processing and marketing of vegetables.

C.      Floriculture

It is the science of flower production.

It involves the scientific study, research and development (R&D) of non-edible flowering and ornamental plants for gardening and floristry, comprising the floral industry.

Floriculture crops include bedding plants, flowering plants, foliage or house plants, cut cultivated greens and cut flowers.

Floriculture includes following sub division

a)      Commercial floriculture

It deals with the cultivation of flowers for commercial purposes.

It includes the commercial production, utilization and marketing of loose flowers and cut flowers, along with ornamental plants such as annuals, biennials, perennials, tree shrubs, climbers and herbaceous plants.

b)      Arboriculture

Arboriculture is the cultivation, management and study of individual trees, shrubs, vines and other perennial plants for aesthetic, scientific and educational purposes.

c)      Landscaping gardening

Landscape gardening is the planning, designing and aesthetic arrangement of land using ornamental plants, buildings and other landscape features to develop and beautify gardens, parks, home grounds, public areas and other outdoor spaces.

d)      Ornamental floriculture

Ornamental floriculture is the study, cultivation and use of ornamental plants for decorating indoor and outdoor spaces, including plants grown for their flowers or foliage and potted flowering and foliage plants used for ornamental purposes.

D.     Plantation crops

Plantation crops are perennial, high-value crops cultivated on a large scale and managed either by individual growers or by organized farms, estates or companies. They generally require processing before consumption. Examples- tea, coffee, coconut, rubber, cashew, cocoa and oil palm.

E.      Spices

Spices are mainly herbaceous plants or their parts, such as seeds, fruits, roots, rhizomes, bark and leaves, used to flavour, colour and enhance the taste of food.

F.       Condiments

Condiments are edible substances used in small quantities to impart or enhance the flavour, taste and especially aroma of food.

Note: Plantation, spice and condiment crops are economically important crops cultivated for food, beverages, oils, flavouring, colouring and enhancing the taste and aroma of food.

G.     Medicinal Plants

Medicinal plants are plants cultivated for their therapeutic properties (e.g., antimicrobial, anti-inflammatory, analgesic and antioxidant activities) and valuable secondary metabolites (e.g., alkaloids, flavonoids, tannins and essential compounds), which are used as raw materials for medicines, drugs and other health products.

H.     Aromatic Plants

Aromatic plants are plants cultivated for their fragrant essential oils, which contain volatile compounds such as menthol, eucalyptol, citronellal, linalool and citral, as well as other aromatic compounds such as phenols, terpenoids and aldehydes. These compounds are used in perfumes, cosmetics, soaps, food flavoring, pharmaceuticals and other products.

I.        Post-harvest Technology and Food Processing

It is an interdisciplinary science and technology applied to horticultural produce after harvest for its conservation, processing, packaging, storage, transportation, distribution, marketing and utilization to meet the food and nutritional requirements of people.

Importance of Horticulture                  

1. Income Generation

Horticultural crops, especially fruits, vegetables and plantation crops, are more prolific yielders compared with other crops. Spices, medicinal, aromatic and floricultural crops are high-value crops and generally fetch higher prices in the market. One hectare of horticultural crops may generate an income of ₹10,000 to ₹1,00,000 or even many times more, depending upon the nature and value of the crop and marketing factors.

2. Employment Generation

Horticultural crops are labour-intensive and generate considerable employment, particularly in the rural sector. These crops are delicate and tender in nature and require careful management from site selection to cultivation, harvesting, processing, marketing and storage, resulting in higher labour requirements. Fruit crops such as grapes and banana require substantial labour, while plantation crops such as tea, coffee and cardamom also provide considerable employment.

Table: Labour requirement in selected horticultural crops

Crop	Labour requirement (man-days/ha/year)
Fruits
Grapes	2,500
Banana	1,000
Vegetables	200
Plantation crops
Tea	875
Coffee	250–390
Cardamom	190
Cereals	143

 

3. Industrial Development

Horticultural crops provide raw materials for various industries. Tea, coffee, rubber, coconut and oil palm support plantation-based industries, while medicinal plants such as Dioscorea, Ocimum, ashwagandha and isabgol are used in medicinal industries. Rose, jasmine, tuberose and sandalwood are used for essential oils and perfumes. Horticultural products are also used in soaps, shampoos, creams, medicines, coir and sago.

4. Religious and Sacred Value

Many plant parts such as leaves, twigs, flowers and fruits possess religious and sacred value and are used in ceremonies and celebrations. Festooning with mango leaves, placing banana plants at entrance gates and using coconut fruits have their own significance.

• Parijat flowers (Nyctanthes arbor-tristis) – associated with Satyabhama.
• Bael leaves (Aegle marmelos) – traditionally offered to Lord Shiva.
• Fruits and flowers – mentioned in ancient scriptures for religious purposes.
• Trees – traditionally worshipped and considered sacred.

5. Food Value

Horticultural crops provide important sources of carbohydrates, fats and proteins. Fruits such as banana and vegetables such as potato and sweet potato are rich in carbohydrates, while almond, walnut and cashewnut are rich in fats and proteins. Banana and sweet potato constitute staple foods in some areas. About 24 bananas, each weighing around 100 g, provide approximately 2,400 calories, as stated in the source.

6. Nutritional Value

Fruits and vegetables are rich in vitamins and minerals and are therefore known as “protective foods.” They supply minerals such as calcium, iron and phosphorus and vitamins such as A, B-complex and C. They also contain various polyphenols and dietary fibre, which contribute to health and proper digestion. Adequate consumption of fruits and vegetables helps maintain health and vigour.

Nutrient	Important horticultural sources
Vitamin A	Mango, papaya, carrot, spinach, bathua leaves
Vitamin B-complex	Cashew nut, bael, amaranthus, chillies
Vitamin C	Barbados cherry, guava, citrus fruits, tomato, aonla, broccoli
Calcium	Litchi, curry leaves, okra, dry karonda
Iron	Apple, ber, guava, spinach, other green leafy vegetables
Phosphorus	Avocado, banana, date, carrot, potato, peas
Potassium	Avocado, banana, spinach, broccoli, brussels sprouts

 

7. Aesthetic Value

Horticultural plants have considerable aesthetic value and are used to beautify surroundings. Fruit trees such as mango, litchi, sapota, mahua and khirni are also valued for their attractive appearance. Horticultural plants are widely used in urban plantations, village landscapes, gardens and parks.

8. Export Value

Horticultural crops have considerable export value and contribute to foreign-exchange earnings.

Important horticultural export crops from India:

• Fruits: Grapes, pomegranate, mango, banana and orange
• Vegetables: Onion, potato, tomato and green chilli
• Flowers: Rose
• Plantation crops: Cashewnut, tea, coffee, coconut and arecanut
• Spices: Black pepper, cardamom, ginger, turmeric and chillies

Major destinations for Indian fresh fruits and vegetables include UAE, Bangladesh, Netherlands, Nepal, Malaysia, Iraq, UK, Sri Lanka and Oman.

9. Environmental Importance

Horticultural trees function similarly to forest trees in maintaining the environment. They help modify the microclimate and provide shelter to birds, reptiles and other microorganisms, thereby contributing to biodiversity. In urban areas, horticultural trees and plants also help improve the surrounding environment.

10. Rural Development Importance

Horticulture contributes to rural development through employment generation and higher returns. Since horticultural crops are labour-intensive and highly remunerative, their cultivation provides income and employment opportunities in rural areas.

11. Yield

Many horticultural crops produce higher yields per unit area than cereal crops. Intensive cultivation and high-yielding varieties contribute to higher productivity in several horticultural crops.

Crop group	All-India productivity, 2024–25
Total Horticulture	12.30 t/ha
Vegetables	18.47 t/ha
Flowers	10.74 t/ha
Spices	2.55 t/ha
Aromatic & medicinal plants	0.92 t/ha
Rice	2.90 t/ha
Wheat	3.55 t/ha

 

12. Horticultural Therapy

Horticultural therapy involves the use of gardening, plants and garden environments to promote physical, mental and social well-being. Activities such as planting, transplanting, pruning, flower arrangement and caring for plants can help reduce stress, improve mood and support rehabilitation.

Examples:

• Lavender (Lavandula angustifolia) – its fragrance is used in sensory gardens and may promote relaxation and reduce stress.
• Rose (Rosa spp.) – flower fragrance, colour and flower-arrangement activities can provide sensory stimulation and promote relaxation.

13. Orchard Tourism

Orchard tourism is a developing concept in which people visit orchards for recreation and participate in agricultural activities such as planting, pruning, grafting and fruit harvesting. It provides urban people with an opportunity to experience agricultural activities and rural life.
