Bearing

Bearing is connotation of flowering and fruiting. When a fruit tree flowers and fruits, it is said in bearing condition. Different fruits have different bearing habits, inflorescences, types of flower, mode and medium of pollination, pollen viability and all these account a lot for the bearing of fruit plants.

Bearing habit

If one observes a mango tree, he/she may find it does produce the fruits terminally on a shoot and it citrus he/she finds the fruits always produced laterally in the leaf axils. The manner or patter in which a plant produces its fruit is known as bearing habit or fruiting habit. Bearing habits are specific to the kind of plant. In determining the bearing habit of any plant three points are to be considered.

Horticultural plants are grown for their produce like fruit, vegetable, flower, medicinal component, spices etc. Therefore, these plants should be managed in such a way that human desires for the purpose of growing them are fully satisfied in terms of quality and quantity of produce. This demands direct manipulation of plant growth itself or plant environment through various inputs. In manipulation of plant development, training and pruning are important for which our knowledge about plant development and its phenology has to be complete. These practices are important in fruit crops.

Planting System

Main objective of layout is maximum number of plant accommodated in per unit area without affecting the efficiency of production. If more than one fruit is included in the orchard plan, each kind should be grouped into individual block. Similarly fruit ripened in particular season should be grouped to facilitate convenience in watch and ward, harvest and post harvest handling. Some kind of fruit trees need pollinators/pollinisers for improving the fruit set.

Orchard

Establishment of orchard is a long term investment. It is require a proper planning, any mistake during the selection of site, planting distance, choice of crop/variety, quality of nursery stock etc. reflect greatly on the orchard performance and efficiency.

Propagation

Plant propagation means multiplication of plant by sexual or asexual method. The success in plant propagation depends on a thorough knowledge of the growth of plants, choice of suitable method and technical skill. The propagation of plants may be done either by the gametes or from the somatic cell, tissues or organs. In other words, propagation may be done by sexual methods or by asexual methods. The details of the methods are presented below.

Nursery

Nursery is a place where seedling, saplings or any other planting materials are raised, propagated, multiplied and sold out for planting. The prerequisites of a successful and remunerative fruit production are the availability of true-to-type, healthy and good quality planting materials. Setting up of a fruit nursery is a long term venture and requires careful planning and expertise, because mistakes committed initially cannot be rectified easily and may adversely affect the return from the investment. Thus, one should pay due attention on every aspects when nursery is to be established.

Mulching

It means covering of soil surface by some organic or inorganic materials for conserving the soil moisture besides covering on the soil moisture several other advantage of mulching. The materials which are used in mulching called mulch.

Weed

Weed in orchards reduce crop yields by competing for moisture, nutrients, light and space. They also harbour insect pests and diseases. When they become large they interfere with orchard operations. Some of weeds climb on the trees and shade the foliage. There are some weeds which are parasitic partially or completely on the host tree e.g. Striga and loranthes on mango.

Nutrients

The nutrients are chemical elements which are absorbed by the plants in more or less quantity to transform light energy into chemical energy and to keep up plant metabolism for the synthesis of organic materials. These materials constitute among other things, foods for humans and animals and a range of raw materials for various industrial uses. Feeding of plants with nutrients is termed as nutrition. Successful growth and production of the plants in general requires a proper supply of the 17 elements. These elements are regarded as essential to life in higher plants.

Water

Water is one of the most important inputs essential for the production of crops. Plants need it continuously during their life and in huge quantities. It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients etc. Both its shortage and excess affects the growth and development of a plant directly and consequently its yield and quality.

Soil needs the application of water to:

Remove stress condition.

Release nutrients in the soil solution for absorption by plants.

Leach or wash out injurious salts from the soil.

Preparation of land for raising crops.

To maintain the temperature and humidity of the soil micro-climate and the activity of soil microbes at optimum level.

For the normal aeration and functioning of roots and shoots of the plants.

Excess water needs to be removed for the normal aeration and functioning of roots and shoots of the plants

Excess water creates unworkable soil condition.

Soil- Soil is the upper most crust of earth surface which supports plant growth. It is defined as a three phase system in which plants grow. These phases are solid, liquid and gas and are essential. Solid part is frame which provides space for other two. This consists of minerals, clay minerals and organic matter. The soil is also a living system with millions of microbes that breakdown organic matter and builds it again.

Some points are following

Microbes are essential and survive only when soil is well aerated and rich in organic matter and devoid of waterlogged conditions.

Texture of soil depends on the size of solid particles and classified as gravel, coarse and fine sand, silt and clay.

Soils are classified according to relative distribution of these particles and there are 12 textural classes.

Likewise, arrangement of these particles is referred as structure, and both texture and structure lend soil physical properties like water holding capacity, aeration and bulk density.

Generally loamy soils and crumb structure are most preferred for fruit crops.

According to level of organic matter, soils are classified as mineral soil or organic soil and soil having more than 20% organic matter is organic soil like peat and muck.

Classification is system of placing an individual or a member in various groups or to categories them according to particular plan or sequence which is in conformity with the nomenclature. From time-to-time for purposes of convenience plants or fruits have been classified in various ways that makes possible to refer them to a large number of kinds under a group name without enumerating or specifying individually. The basis of these groupings varies according to the features of fruits or growth of the fruit plants that have been under classification at the time.

Knowledge of classification of horticultural plants is very useful to the horticulturists because it serves: (1) to identity and name them, (2) to afford at least some idea of the closeness of their relationship i.e. line of descent to other kinds, (3) to suggest with what other kind they possibly may or may not be interbred or crossed, (4) to suggest the kinds with which they possibly may or may not be inter-grafted, and (5) often to suggest certain soil and the cultural requirements, climatic adaptations etc. However, the classification of fruit trees or fruits and vegetables on the basis of consumer’s rating also gained attention in recent years. The consumers’ rating is mainly based on the size, shape, nutritive value and marketability of them. Each of these classifications is quite different from the other classification or groupings.

Basically, the fruit trees, as suggested by many authors, have been classified on the basis of their botany comprising of taxonomic ancestry, morphologic features, physiological functions, adaptability etc. or on the basis of agricultural and horticultural requirements. But the consumers’ rating has not been properly covered in the earlier classification. Generally based on botanical relationship the plants are classified as under.

Fruits and vegetables play an important role in balanced diet. These provide not only energy rich food but also provide vital protective nutrients/elements and vitamins. Comparatively fruits and vegetables are the cheapest source of natural nutritive foods. Since most of Indians are vegetarians, the incorporation of horticulture produce in daily diet is essential for good health. Realizing the worth of fruits and vegetables in human health, Indian Council of Medical Research (ICMR) recommended the use of 120g fruits and 300g vegetables per capita per day. With the growing awareness and inclination towards vegetarianism worldwide the horticulture crops are gaining tremendous importance.

Functions of fruits and vegetables in human body

Fruits and vegetables provide palatability/taste.

Improves appetite and provides fiber to overcome constipation.

They neutralize the acids produced during digestion of proteins and fatty acids.

They improve the general immunity of human body against diseases, deficiencies etc.

They are the important source of vitamins and minerals for used in several bio-chemical reactions occur in body.

Horticulture means the cultivation of garden plants. The garden plants are comprised of fruits, vegetables, ornamentals etc. The culture covers the operation from raising and planting of saplings to the ultimate use of the products and, as such, it is the most intensive of all the agricultural sciences. However, the concept of growing plants in garden or in an enclosure does not fit well in the changed perspective where large scale cultivation of fruits, vegetables and flowers extending over several square kilometers, in many a place nowadays, delimits the boundary of garden.

Importance of Horticulture

The importances of horticulture are established not only as a source of nutritious foods but also in many other ways which are narrated in the following points:

Social- Due to the long association, the fruits are seen to have a permanent seat in the social life of man. As a consequence, various fruits have acquired their place in art, music, literature, customs and habits of various nations of the world. The description of fruit as symbolic insertion in the poems and literatures, the use of whole fruit plant or part thereof in various social festive and public gathering, and conferring titles to individuals in the name of fruits or naming a region or whole district after the name of a fruit are nothing but an indication of their popularities and social position in various countries.

The term ‘Horticulture’ is derived from two Latin words, Hortus meaning Garden and Cultura meaning Cultivation. In ancient days the gardens had protected enclosures with high walls or similar structures surrounding the houses. The enclosed places were used to grow fruits, vegetables, flowers and ornamental plants. Horticulture differs from agriculture and forestry in specializing the cultivation of garden crops. The garden crops include fruits, vegetables, flowers, ornamental trees, spices, plantations, medicinal and aromatic plants. Horticultural crops do not give food grains. The products of horticultural crops such as fruits and vegetables are highly perishable so that they are utilized in the fresh state. In general horticultural crops need more intensive cultivation (i.e. need more work) than the agricultural crops.

Special Features of Horticulture

As horticultural crops generally need intensive cultivation, they require a large input, capital, labour and technology per unit area of land.

Many cultural operations are specific to horticultural crops. The cultural operations such as propagation, fertilization, training, pruning, harvesting and marketing are skilled operations and these are specific to horticultural crops.

Mostly the horticultural products are utilized in the fresh state and are highly perishable.

Most of the horticultural crops are the rich sources of vitamins and minerals.

Gratification or aesthetic sense is an exclusive phenomenon for horticultural science.

Leafy vegetables are rich sources of provitamin-A, vitamin C and minerals like calcium, magnesium, iron, etc., They are the riches sources of roughes or fibres essential in human diet. The ICMR recommended dietary allowances of green leafy vegetables for adult women is 100g/day and men are 40g/day while for school children above 10 years it is 50g/day. Greens are rich in vitamins and minerals essential for healthy functioning of organs of body. Amaranth, beet leaf, spinach, fenugreek, etc., are the major leaf vegetables grown in India. In addition, a number of under-utilized annual crops are also grown as leaf vegetables in specific regions. Tender stems and leaves of a number of perennial crops are rich sources of vitamins and minerals and are used for cooking.

10.1. Amaranth (Amaranthus sp)

Amaranth is the most common leaf vegetable grown in India. Amarnath is an annual herb with erect growth and scarce to profusely branching habit. Stem is succulent and green or purple or mixed shades of these two. There are two sections in Amaranthus, viz., Amaranthus and Blitopsis. Majority of leaf cultivars grown in India belong to Amaranthus tricolor. Among the several kinds of greens Amaranthus occupy a special place because it has a large number of species grown in one or the other part of country.

Some of the important improved varieties released are CO-2 and CO-5 from TNAU, Coimbatore, Pusa Kiran, Pusa Kirti and Pusa Lal Choulia from IARI, New Delhi, Arka Arunima and Arka Suguna from IIHR, Bangalore. Amaranth are popular all over India by different names. While in northern parts it is popularly known as choulia, in south it is popularly called as keerai or cheera or koora or soppa. The general composition of amaranth is given below:

9.1. Onion (Allium cepa L.)

The onion (Allium cepa), which is also known as the bulb onion, or common onion is the most widely cultivated species of the genus Allium. It has been used as food since time immemorial and is an important vegetable all over the world. The genus Allium also contains a number of other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion (A. fistulosum), Egyptian onion (A. proliferum), and Canada onion (A. canadense). The vast majority of cultivars of A. cepa belong to the “common onion group” (A. cepa var. cepa) and are usually referred to simply as “onions”. The Aggregatum Group of cultivars (A. cepa var. aggregatum) includes both shallots and potato onions. Onion is suggested to have been originated in Asia, particularly Pakistan and Iran.

China is the largest onion producer in the world followed by India. Largest area under onion is in India followed by China. The major onion producing state are Maharashtra, Karnataka, Madhya Pradesh, Rajasthan, Gujarat, Bihar, Andhra Pradesh, Tamil Nadu and Orissa.

Cultivars/Varieites: Onion varieties differ in size, colour of skin, pungency and maturation. The most popular varieties under cultivation are Agrifound Dark Red, Agrifound Light Red, Agrifound Red, Agrifound Rose, Arka Bindu, Arka Kalyan, Arka Niketan, Arka Pragati, Baswant 780, Brown Spanish, Co-1, Co-2 Co- 3, Co-4, Early Grano, Hisar II, Kalyanpur Red Round, MDU 1 N-2-4-1, N-53, N-257-9-1, Punjab 48 (S 48), Pusa Madhavi, Punjab Red Round, Punjab Selection, Pusa Ratnar, Pusa Red, Pusa White Flat, Pusa White Round, Udaipur 101, 102 & 103.

Leguminous vegetables include peas, French bean, Lima bean, broad bean, cowpea, hyacinth bean, winged bean etc. They belong to the family Fabaceae (Syn. Leguminosae). These are cultivated either as sole crop is sometimes as intercrop. In some areas they are used in backyard cultivation also. Most of them are short duration crops and are self pollinated.

8.1. Peas (Pisum sativum L.)

The pea (Pisum sativum L.) is a very common nutritioius vegetable grown in cool season throughout the world. It belongs to the family Fabaceae (Syn. Leguminaceae) and genus Pisum. A pea is most commonly the small spherical seed or the seedpod of the pod fruit Pisum sativum L. The pea cultivars are grouped into several groups based on shape of seed, plant height, maturity and use of pods. This crop is cultivated for its tender and immature pods for use as vegetable and mature dry pods for use as a pulse. In both the cases the seeds are separated and used as vegetable or pulse. The central Asia is regarded as the place of origin for all legumes including pea. Based on the genetic diversity, Central Asia, the Near East, Abyssinia and the Mediterranean is considered to be its centre of Origin. Cultivated garden pea is not seen in wild state and it might have been originated from wild field pea or other related species. In India it widely cultivated states of Uttar Pradesh, Bihar, Haryana, Punjab, Himachal Pradesh, Orissa and Karnataka. Followed by Madhya Pradesh, Himachal Pradesh, Assam and Jharkhand.

Cultivars/Varietie: Peas varieties are grouped based on maturity (early, mid season and late) plant height (Bush or dwarf, medium tall and tall). The major cultivars under cultivation in different parts of the country are Arkel, Bonneville, Harbhajan, FC-1, Arka Ajit, UN 53-6 (whole edible type), Jawahar Matar 1, Jawahar Matar 2, Jawahar Matar 3, Jawahar Matar 4, Jawahar Matar 5, Jawahar Peas 83, JP 4 (JM 6), JP 19, Lincoin, Mattar Ageta 6, Pantnagar Matar 2, Pant Uphar (IP 3), P 88, PRS 4,Ooty-1 and VL 3.

7.1. Okra or Bhindi (Abelmoschus esculentus L.)

Okra (Bhindi) is a member of Malvaceae family, earlier known as Hibiscus esculentus, and is an annual vegetable crop grown from seeds in tropical and subtropical parts of the world. Okra, also known as “lady finger” or “gumbo”, is a highly nutritious green edible pod vegetable. Botanically, this perennial flowering plant belongs to the mallow family but is grown as an annual. It is named scientifically as Abelmoschus esculentus. Okra originated in tropical and subtropical Africa and India is suggested to be the secondary centre of origin. There are four species under Abelmoschus genus which includes both cultivated and wild forms. They are A. esculentus, A. manihot, A. caillei and A. moschatus. In India, Okra is widely cultivated in states of Andhra Pradesh, West Bengal, Orissa, Bihar Uttar Pradesh, Karnataka, Assam West Bengal, Orissa, Gujarat and Bihar.

Cultivars/Varieties: Okra varieties differ in growth habit, height of plant, presence of purple pigmentation and ridges on fruit. The popular varieties under cultivation in different parts of the country are Arka Abhay, Arka Anamika, Azad Kranti, Co 1, MDU1, Gujarat Bhindi 1, Harbhajan Bhindi, Hisar Unnat, Parbhani Kranti, Perkins Long Green, Punjab 7, Punjab 8, Punjab Padmini, Pusa A 4, Pusa Makhmali, Pusa Sawani, Red Bhindi, TN Hybrid 8 and Varsha Uphar. Besides, a number of hybride from many private sector agencies/seed companies are marketed. Of these, Varsha, Vijay, Adhunik, Panchali, Hybrid No. 6,7 and 8, Nath Sobha, Supriya, Sungro 35, Aroh 1, - 2, -3, -9 and are more popular.

Uses

Different parts of the plant are used for different purposes. Abelmoschus moschatus Medik. Leaves and seeds are considered as valuable traditional medicine. Abelmoschus moschatus is also called ‘musk okra’ a medicinal plant belonging the same family. The leaves and new shoots of this plant is also used as vegetable. The aromatic seeds of this plant are aphrodisiac, ophthalmic, cardio tonic, antispasmodic and used in the treatment of and intestinal complaints and anxiety.

6.1. Potato (Solanum tuberosum L.)

Potato, Solanum tuberosum, is a starchy, tuberous crop belonging to the Solanaceae family. The name potato originally referred to a type of sweet potato, batata, in Spanish. Potatoes are occasionally referred to as “Irish potatoes” or “white potatoes” in the United States, to distinguish them from sweet potatoes. The potato was believed to be first domesticated in the region of southern Peru and extreme northwestern Bolivia between 8000 to 5000 BC. The potato diffused widely after 1600, becoming a major food resource in Europe and East Asia. Greater geographic mobility of farmers led to the rapid spread of potato cultivation throughout China, and India. China is now the world’s largest potato producer and nearly one third of the world’s potatoes are produced in China and India.

Today potato is the fourth major food crop after rice, wheat and maize in the world. In India potato is a very important crop and are mainly produced in the states of Uttar

Cultivars/Varieties: Most of the improved potato varieties were developed by CPRI, Kufri, Shimla. Most of the earlier varieties released as clonal selections derived from foreign varieties have been replaced with high yielding new varieties from the same institute. The popular varieties under cultivation now are Kufri Sindhuri, Kufri Chandramukhi, Kufri Jyothi, Kufri Lauvkar, Kufri Muthu, Kufri Dewa, Kufri Badshah, Kufri Bahar, Kufri Lalima, Kufri Swarna, Kufri Jawahar, Kufri Ashoka, Kufri Megha, Kufri Sutlej, Kufri Pukhraj, Kufri Chipsona-1, Kufri Chipsona-2 and Kufri Giriraj.

Uses

Potatoes are used in different ways like boiled, fried, baked and roasted. Potatoes are used to brew alcoholic beverages such as vodka, potcheen, or akvavit.They are also used as food for domestic animals. Potato starch is used in the food industry as, for example, thickeners and binders of soups and sauces, in the textile industry, as adhesives, and for the manufacturing of papers and boards. Many companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in bioplastic products; other research projects seek ways to use the starch as a base for biodegradable packaging. Potato skins, along with honey, are used in folk medicine for burns in India. Burn centers in India have experimented with the use of the thin outer skin layer to protect burns while healing. The potato is best known for its carbohydrate content, which is in the form of starch. Because of its high starch content, it is a staple food in several parts of world including in some parts of India. A small but significant portion of this starch is resistant to digestion by enzymes in the stomach and small intestine, and so reaches the large intestine essentially intact, thereby, increasing its physiological significance. Besides these the potato also provides various other nutritional constituents to the body. Potato is also processed into various products like chips, powder, pappad, savory items.

Carrot, radish, turnip and beet root are major root crops grown in India. In addition, root crops like rutabaga, parsnip, parsley, chervil and celeriac are grown in a limited scale in different parts of the world. There are several other roots and modified underground plant parts that grow in forests and consumed by tribes, but they are not commercially cultivated. Carrot, radish, turnip and beet root are generally consumed as cooked vegetables or fresh salads or as pickled vegetables.

5.1. Carrot

Carrots belong to the Umbelliferae family, named after the umbrella-like f lower clusters that plants in this family produce. As such, carrots are related to parsnips, fennel, parsley, anise, caraway, cumin and dill. Carrot, Daucus carota L. is believed have been primarily originated in Afghanistan, South western Asia and Mediterranean region. Daucus carota ssp. Carota is the most common wild form in Europe and South West Asia, and the present day cultivated carrots have most probably originated from this sub-species.

Haryana, Andhra Pradesh, Punjab and Tamil Nadu, Karnataka, Uttar Pradesh and Assam are the major producers of carrot in India.

Cultivars/Varieties: Varieties with long, orange coloured and smooth roots are preferred in India. Both indigenous and exotic varieties having different root length, shape and colour are grown. Temperate or European type varieties are Nantes, Half long, Early Nantes, Chantenay, Chaman, Pusa Yamadagni and Ooty-1, which require low temperature of 4-8°C for flowering. Tropical or Asiatic type varieties do not require low temperature for flowering and can be grown in plains also. The varieties belonging to this group are Pusa Kesar, Pusa Meghali and Hisar Gairic. Some varieties like Gold King, Indian Kuroda and Super Kuroda are also marketed by private seed companies.

In Solanaceae family there are 85 genera, which includes both tuberiferous and non-tuberiferous plants. Among the non-tuberiferous, tomato, brinjal and chilli are the important fruit vegetables.

4.1. Tomato (Lycopersicon esculentum Mill.)

Tomato has originated in Peru and Mexican region of South America. It got its name form the azetc work “Tomatl”. In India tomato is the second largest cultivated vegetable after potato. Though it is produced in almost entire country, the major producer states are Andhra Pradesh, Karnataka, Orissa, West Bengal, Bihar, Gujarat, Madhya Pradesh and Maharashtra.

Cultivar/Varieties: A large number of varieties/hybrids of tomatoes are under cultivation. The most popular among them are Arka Rakshak, Arka Samrat, Arka Saurabh, Arka Vikash, ARTH 3, ARTH 4, Avinash 2, BSS 90, CO3, HS 101, HS 102, HS 110. Hisar Anmol, Hisar Arun, Hisar Lalima, Hisar Lalit, Krishna, KS 2, Matri, MTH 6, NA 601, Naveen, Pusa 120, Punjab Chhuhara, Pant Bahar, Pusa Divya, Pusa Early Dwarf, Pusa Hybrid 1, Pusa Hybrid 2, Pusa Hybrid 4, Pusa Ruby, Pusa Sheetal, Pusa Uphar, Rajni, Rashmi, Ratna and Rupali.

Uses

Tomato adds richness to any dish it is added. Besides using for culinary purpose tomato is also used as salad and dressings and also as adjuvant in several locally available fresh snacks. It is used for thickening of gravies in many Indian curries. As a processed product tomato sauce and ketchup are on top of favourites. It is not only delicious in taste but also rich in its medicinal value. The pulp and juice are mild aperient, a promoter of gastric secretion and blood purifier. It is also considered to be intestinal antiseptic. It is said to be useful in sour mouth, canker of mouth and chronic dyspepsia.

Cole crops are a group of vegetables belonging to the family Brassicaceae (Syn: Cruciferae) and include cabbage, cauliflower, knoll khol, kale, Brussel sprouts, sprouting broccoli, etc. Cole crops are found spread all over Europe from the Mediterranean region, which is supposed to be the centre of origin. In the ancient Egyptian and Asian civilization, there was mention of cole crops and also by Aristotle in his writings on ‘Enquiry into plants’ there was mention about three types of coles. It is believed that it was first collected for food at the beginning of Neolithic times before being cultivated, and the cultivated forms of cabbage group like, cabbage, savoy, kales, collard, broccoli, Brussels sprouts, cauliflower and kohlrabi gradually originated from wild species through mutation, human selection and adaptation.

Among the cole crops in India cauliflower and cabbage are the two most important crops while Kohlrabi is grown very less. In India it is cultivated in states of Uttar Pradesh, Karnataka, Maharashtra, Bihar, West Bengal, Punjab and Haryana. It is also grown in milder climates in southern India like Ooty, Bangalore, etc.

3.1. Cabbage (Brassica oleracea L.f. alba)

Cabbage, Brassica oleracea Linne (Capitata Group) is a popular vegetable belonging to the family Brassicaceae (or Cruciferae) and is used as a leafy green vegetable. It is in the same genus as the turnip – Brassica rapa. Cabbage leaves often have a delicate, powdery, waxy coating called bloom. The occasionally sharp or bitter taste of cabbage is due to glucosinolate(s). Cabbages are also a good source of riboflavin.

In India cabbage is widely grown in the states of Uttar Pradesh, Orissa, Bihar, Assam, West Bengal, Maharashtra and Karnataka.

Cultivars/Varieties: Cabbage cultivars are classified on the basis of colour of head and maturity. In India white cabbage is important and these are available in pointed, round and flat shapes. Of these round cabbages are preferred. Common cabbage varieties grown are Golden Acre, Pride of India, Copenhagen Market, Red Acre, Pusa Drum Head, Pride of India, Pusa Agethi, Pusa Muktha, KGMR-1, Kateri, Hardam and Nakshatra.

Cucurbits form an important and a big group of vegetable crops cultivated extensively in this country. This group consists of a wide range of vegetables, either used as salads (cucumber) or for cooking (all the gourds) or for pickling (cucumber) or as dessert fruits (muskmelon and watermelon) or candied or preserved (ash gourd). They are of tremendous economic importance as food plants.

2.1. Ash Gourd (Benincasa hispida)

Ash gourd (Benincasa hispida L.) belongs to the family Cucurbitaceae. The winter melon, also called white gourd, ash gourd, or “fuzzy melon”, is a vine grown for its very large fruit, eaten as a vegetable when mature. It is the only member of the genus Benincasa. This is a monotypic genus and the only cultivated species is Benincasa hispida (Thunb) Cogn, commonly known as ash gourd or petha. It has a Sanskrit equivalent ‘Kooshmanda’ indicating its antiquity in India.

Originally cultivated in Southeast Asia, the ash gourd is widely grown in China, India and other parts of East Asia. The immature melon has thick white flesh that is sweet when eaten. By maturity, the fruit loses its hairs and develops a waxy coating, giving rise to the name wax gourd, and providing a long shelf life. The ash gourd is known by many other names in India regional wise like komora (Assamese), pethakaddu (Hindi), boodagumbala (Kannada), Kumbalanga (Malayalam), Kohla (Marathi), neer poosanikai (Tamil) and Boodida gummadikaya (Telugu).

Uses

Ash gourd have enormous medicinal properties as it makes a valuable place as a popular natural cure of ailments in traditional medicinal practice. Being low in calories it is an ideal vegetable for diabetic patients and good for weight control. It also acts as a good detoxifying agent.

As per Ayurveda, ash gourd is used to treat epilepsy, asthma, lung diseases, urine retention, internal haemorrhage, and cough. It is said that the fruit juice is also effective in cases of mercury poisoning and snakebite. It could also treat mouth cancer, protecting teeth and gums when a mouth gargle of the juice is done regularly. It is also effective in bleeding of gums. Ash gourd is easily digestible and keeps the body cool. It is a natural blood purifier.

Vegetables are important accompaniments for the main course of meal, which is by and large a carbohydrate-based food (wheat, rice or millets). It not only makes the meal more palatable, but also wholesome with its diverse color, smell and taste. More importantly it facilitates the easy movement of food through the bowel, better absorption by the body and till the elimination. Besides hunger satiation, it helps to maintain the health by providing the essential micronutrients and prevent lifestyle disorders.

As a nutritious food, it provides the vitamins, minerals and phyto-chemicals which are required in small quantities for physiological processes and metabolic activities. They are cheap sources of beta-carotene, vitamin-B complex, folic acid, vitamin C, vitamin E, etc. They are rich in minerals like iron, calcium, magnesium, phosphorus, etc., and dietary fibres. It has now been proved that minerals are better absorbed by the body in presence of several other factors of plant matrix, than as mineral supplements. It also provides small amounts of carbohydrates and proteins. Vegetables are important as protective foods as their consumption prevents many diseases. They are important sources of antioxidants and phytochemicals. Each vegetable has been found to have certain specific phyto-chemical which besides being a free radical scavenger, is also inhibitor of certain conditions responsible for disease development.

Among the vegetables, tubers like cassava, potato and sweet potato being highly rich in carbohydrates, served as staples for several countries for very long time, in the history. For the same reason, there are a variety of food products based on these tubers. Others like carrot, radish, beetroot, and turnip in root vegetables, onion and garlic among bulbous crops; tomato, brinjal (egg plant), okra and capsicum among fruit vegetables serve as sources of phytochemicals (carotenoids, anthcyanins, lycopene, betalain, capsicum, bassiniloids, etc.). Beans, peas, cowpea, and other leguminous vegetables are important sources of proteins and leafy vegetables (greens) contribute to the much-needed minerals, vitamins and fibre (roughages) in the diet. Allicin and diallyl disulphide found in onion and garlic control blood cholesterol besides being anti-bacterial. The diphenylamine in onion is effective against diabetes. The ‘Charantin’ found in bitter gourd have hypoglycaemic activity. Diosgenin in yams are used for manufacture of contraceptive drugs. Cole crops like cabbage, cauliflower, Brussel sprouts and sprouting broccoli have anti-carcinogenic properties mainly due to hydrolysed glucosinolate derived isothiocynates and indoles. Similarly, health benefits and curative properties of many indigenous and exotic vegetables have been mentioned in several classical texts of India and China.

Tamarind (Tamarindus indicus L.) belongs to the family Fabaceae. Genus Tamarindus is a monotypic taxon having only one species. Tamarind is native to tropical Africa, probably Sudan, where it grows wild and is cultivated throughout South-East Asia and America. It is also found growing in Camaroon, Nigeria and Tanzania. Tamarind has a long gestation period of 10-20 years and long-life span of even 100 years.

Cultivars/Varieties: In some regions the type with reddish flesh is distinguished from the ordinary brown-fleshed type and regarded as superior in quality. There are types of tamarinds that are sweeter. One in Thailand is known as ‘Makham waan’. Another one is known as ‘Manila Sweet’. No other improved or named varieties are available.

Uses

Tamarind pulp is an important condiment as a sour ingredient in the Indian cuisine. Pulp has an excellent keeping quality. Timber is used for making agricultural implements. The wood yields excellent charcoal and is used for making gunpowder. Starch is obtained from seeds and is used in the textile industry. Seeds can be fed to animal after roasting and removing the outer skin. Seed is also a good source of tanning. Oil is obtained from seeds and is used in paints and varnishes. Leaves and flowers are also edible. It is rich in medicinal properties. Fruits is considered as digestive, carminative and laxative. With the addition of water and sugar, tamarind yields a cool drink which is quite popular in Latin America.Today India is the largest producer of tamarind in the world.

Fragaria is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. It is a low perennial creeping herb which is widely grown in temperate and subtropical regions of the world.

There are more than 20 described species and many hybrids and cultivars. Cultivated strawberries are based on two species, Fragaria chiloensis (L) Duch., native to the west coast of North America and Fragaria virginia Duch., native to eastern coast of North America. Hybrids of these two species are ancestors to all the modern strawberries.
