Explanation

Horticulture is a branch of agriculture that deals with cultivation of fruits, vegetables, and ornamental plants.

Explanation

The word horticulture is derived from the latin words ‘hortus’ meaning garden and ‘colere’ meaning to cultivate.

Explanation

Horticulture is both a science and an art of growing plants with improved growth, quality, yield, and with resistance to diseases, insects, stress etc.

Explanation

There are four main classes of horticulture: (i) Pomology (fruit farming),(ii) Olericulture (vegetable farming), (iii)Floriculture (flower farming), (iv) Landscape gardening.

Explanation

The term pomology is derived from the Latin word ‘pomum’ means fruit and ‘logy’ means study.

Explanation

Pomology deals with development, enhancement of fruit quality, cultivation techniques, regulation of production periods and reduction of production cost of fruits.

Explanation

Olericulture is the science of growing vegetables. 

Explanation

Vegetable farming can be classified into: i) Kitchen or Nutrition gardening ii) Commercial gardening iii) Vegetable forcing.

Explanation

Kitchen gardening is growing of vegetables in small scale at household. e.g. Beans, Cabbage, Lady’s finger, Tomato, Brinjal, Carrot, Spinach etc.

Explanation

Government of Tamil Nadu has launched Uzhavan (farmer) mobile application. It can be used by farmers to gather information on farm subsidies, farm equipment’s, crop insurance and weather conditions. It also provides information on available stock of seeds and fertilizers in local government and private stores.

Explanation

Commercial gardening: It is the production of vegetables in large scale to be sold in markets.

Explanation

Vegetable forcing: It is the method of growing vegetables in buildings, green houses, cold farms or under other artificial growing conditions. It is the most intensive type of vegetable growing. e.g. Cabbage, Tomato, Brinjal etc.

Explanation

Green House or Poly House: It is a framed structure covered with transparent material to grow crops under partially or fully controlled environmental conditions to get optimum growth and productivity. It is the fastest growing sector in the agriculture worldwide.

Explanation

Advantages of Greenhouse

1. Disease-free plants can be produced continuously.
2. Water requirement of crops is very less.
3. Yield is very high compared to outdoor cultivation.
4. Limited pesticide is needed.
5. It protects plants from uncertain weather.

Explanation

Floriculture is the art of cultivation of flowering and ornamental plants in garden for beauty or floristry. It is concerned with growing traditional flowers, cut flowers, bedding plants, foliage potted plants, arboriculture trees, turf grass for beautification and value added products like essential oils, pharmaceutical and nutraceutical compounds. 

Explanation

Some of the plants by floriculture techniques are, Geraniums (Pelargonium), Busy lizzies (Impatiens), Chrysanthemum and Petunia.

Explanation

Pradhan Mantri Fasal Bima Yojana (PMFBY): It is an agricultural crops insurance scheme of Indian government. Under this scheme the central government provides insurance cover and financial assistance to farmers. It was launched on 18th February 2016.

Explanation

Uses of flowers

1. Flowers are used for decoration purpose.

3. They impart color and beauty to the garden.
4. They increase country’s economy.

Explanation

Landscape horticulture is the study of designing and constructing landscapes in homes, business firms and public areas to imitate natural scenery.

Explanation

Organic manures are predominantly derived from plant debris, animal faeces and microbes. They make the soil fertile by adding nutrients like nitrogen.

Explanation

Animal Manure: It consists of faeces and urine from livestocks like cattle, horses, pigs, sheep, chickens, turkeys, rabbits, etc. Manures from different animals have different qualities and different applications.

Explanation

Farmyard manure: It is a mixture of cattle dung, urine, litter material and other dairy wastes. On an average well decomposed farm yard manure contains 0.5% Nitrogen, 0.2% available phosphate and 0.5% available potash.

Explanation

Sheep and Goat manure: It contains higher nutrients than farm yard manure. It contains 3% Nitrogen, 1% phosphorus pentoxide and 2% potassium oxide.

Explanation

Compost is a soil conditioner as well as a fertilizer that is rich in nutrients. It is produced by natural decomposition of organic matter such as crop residues, animal wastes, and food wastes, industrial and municipal wastes by microorganisms under controlled conditions.

Explanation

Green manure is obtained by collection and decomposition of green leaves, twigs of trees, field bunds etc. Green manure improves soil structure, increases water holding capacity and decreases soil loss by erosion.

Explanation

Green manure also helps in reclamation of alkaline soils and reduces weed proliferation. It is manure obtained from un-decomposed green material derived from leguminous plants e.g. Sunhemp (Crotolaria juncea), Dhaincha (Sesbania aculeata), and Sesbania (Sesbania speciosa).

Explanation

Bio fertilizers are substances that contain living microorganisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promote growth by increasing the supply or availability of primary nutrients to the host plant.

Explanation

Rhizobium: Rhizobium is a soil bacterium that colonizes the roots of leguminous plants to form root nodules. The bacteria fix atmospheric nitrogen and convert them to ammonia.

Explanation

Azospirillum: Azospirillum bacteria have the ability to use atmospheric nitrogen and transport this nutrient to the crop plants. It is inoculated on maize, barley, oats and sorghum crops. It increases productivity of cereals by 5 -20%, of millets by 30% and fodder by over 50%.

Explanation

Azotobacter: Application of Azotobacter bacteria has been found to increase yield of wheat, rice, maize and sorghum. Apart from nitrogen fixation, these organisms are capable of producing antifungal and antibacterial compounds.

Explanation

Mycorrhizae: These fungi have symbiotic association with the roots of vascular plants. They increase the uptake of phosphorus. e.g. Citrus, Papaya.

Explanation

Azolla: Azolla is a free floating, aquatic fern found on water surfaces having a cyanobacterial symbiotic association with Anabaena. It is a live floating nitrogen factory using energy from photosynthesis to fix atmospheric nitrogen.

Explanation

Tamil Nadu Government has recently launched ‘Biofertiliser Scheme’. It is aimed at better management of natural farming and helps to boost and maintain soil fertility.

Explanation

Most medicines are obtained either directly or indirectly from plants. All the major system of medicines such as Ayurveda, Yoga, Unani, Siddha, Homeopathy (AYUSH) use drugs obtained from plants and animals.

Explanation

Homeopathy use drugs obtained from plants. These drugs from medicinal plants are called secondary metabolites.

Explanation

Plants produce primary metabolites for their own living e.g. carbohydrates, amino acids etc., 

Explanation

The secondary metabolites for plants are used for protection, competition and species interaction. e.g. alkaloids, terpenoids, flavonoids etc.

It contains 34 identified active phytoconstituents from herbal resources. It works by controlling blood sugar levels.

Explanation

Mushroom cultivation is a technology of growing mushrooms using plant, animal and industrial waste. In short it is wealth out of waste technology. This technology has gained importance worldwide because of its dietary fibers and protein value.

Explanation

Mushroom is a fungi belonging to basidiomycetes. It is rich in proteins, fibers, vitamins and minerals. 

Explanation

There are more than 3000 types of mushrooms. e.g. Button mushroom (Agaricus bisporus), Oyster mushroom (Pleurotus sps.), Paddy straw mushroom (Volvariella volvacea).

Explanation

Major stages of mushroom cultivation are Composting, spawning, casing, pinning and harvesting.

Explanation

Composting: Compost is prepared by mixing paddy straw with number of organic materials like cow dung and inorganic fertilizers. It is kept at about 50°C for one week.

Explanation

Spawning: Spawn is the mushroom seed. It is prepared by growing fungal mycelium in grains under sterile conditions. Spawn is sown on compost.

Explanation

Casing: Compost is covered with a thin layer of soil. It gives support to the growing mushroom, provides humidity and helps regulate the temperature.

Explanation

Pinning: Mycelium starts to form little bud, which will develop into mushroom. Those little white buds are called pins.

Explanation

Harvesting: Mushroom grow better in 15°C -23°C. They grow 3 cm in a week which is the normal size for harvesting. In the third week the first flush mushroom can be harvested.

Explanation

Preservation: Discoloration, weight and flavor loss are the main problems during harvesting of mushrooms.

Explanation

The following methods are used to increase their life. (i) Freezing (ii) Drying (iii) Canning (iv) Vacuum cooling  (v) Gamma radiation and storing at 15°C.

Explanation

Hydroponics is the method of growing plants without soil, using mineral nutrient solutions in water. The containers are made of glass, metal or plastic. They range in size from small pots for individual plants to huge tank for large scale growing.

Explanation

Hydroponics was demonstrated by a German Botanist Julius Von Sachs in 1980.

Explanation

Hydroponics is successfully employed for the commercial production of seedless cucumber and tomato. Plants are suspended with their roots submerged in water that contain plant nutrients. 

Explanation

In Hydroponics the roots absorb water and nutrients, but do not perform the anchoring function. Therefore, the plants must be mechanically supported from above.

Explanation

Importance of hydroponics

(i) Conservation of water and nutrients.

(ii) Controlled plant growth.

(iii) In deserts and Arctic regions hydroponics can be an effective alternative method.

Explanation

The aeroponic system is the high-tech type of hydroponic gardening. The growth medium in this type is primarily air. The roots hang in the air and are misted with nutrient solution. The misting is usually done for every few minutes, as roots will dry out rapidly if the misting cycles are interrupted.

Explanation

In aeroponic plants a timer controls the nutrient pump much like other types of hydroponic systems except that the aeroponic system needs a short cycle timer that runs the pump for a few seconds every couple of minutes.

Explanation

Aquaponics is a system of a combination of conventional aquaculture with hydroponics in a symbiotic environment, in which plants are fed with the aquatic animals’ excreta or wastes.

Explanation

The animal wastes are broken down by nitrifying bacteria initially into nitrites and later into nitrates that are utilized by the plants as their nutrients. Thus the wastes are utilized and water is re-circulated back to the aquaculture system.

Explanation

Aquaponics consists of two main parts, aquaculture- for raising aquatic animals like fish and hydroponics-for raising plants.

Explanation

Green leafy vegetables like Chinese cabbage, lettuce, basil, coriander, parsley, spinach and vegetables like tomatoes, capsicum, chilies, bell peppers, sweet potato, cauliflower, broccoli and egg-plant can be grown in aquaponics.

Explanation

Dairy farming involves rising of cattle for milk production. It involves the proper maintenance of cattle, along with collection and processing of milk and milk products which are useful to man. Dairying is the production and marketing of milk and its products.

Explanation

The Indian cattle include cows and buffaloes. They are domesticated for milk, meat, leather and transportation. They belong to two different species, Bos indicus (Indian cows and bulls) and Bos bubalis (buffaloes). 

Explanation

The Indian cattle animals are reared for milk and farm labor. They are classified into three types: Dairy breeds, Draught (or) Draft breeds, Dual purpose breeds.

Explanation

Dairy breeds: Dairy animals are domesticated for obtaining milk. The cows (milk producing females) are high milk yielders (milch animals). The dairy breeds are: Indigenous breeds, Exotic breeds.

Explanation

Indigenous breeds are native of India. They include Sahiwal, Red Sindhi, Deoni and Gir. These cattle are well built with strong limbs, prominent hump and loose skin. Milk production depends on the duration of the lactation period (the period of milk production after the birth of a calf). These local breed animals show excellent resistant to diseases.

Explanation

Exotic breeds (Bos Taurus) are imported from foreign countries. They include Jersey, Brown Swiss and Holstein-Friesian etc. These foreign breeds are selected for long lactation periods.

Explanation

Draught (or) Draft breeds: They are used for agricultural work, such as tilling, irrigation and carting. These include Amritmahal, Kangayam, Umblachery, Malvi, Siri and Hallikar breeds. Bullocks are good draft animals while the cows are poor milk yielders.

Explanation

Dual purpose breeds: The cows of these breeds provide milk and the bulls are useful for farm work. In India these breeds are favored by farmers. They include Haryana, Ongole, Kankrej and Tharparkar.

Explanation

Indigenous Draught breeds – Native to Tamil Nadu

Kangayam: It originated in Kangayam and is observed in Dharapuram, Perundurai, Erode, Bhavani and part of Gobichettipalayam Taluk of Erode and Coimbatore district.

Pulikulam: This breed is commonly seen in Cumbum valley of Madurai district in Tamil Nadu. It is also known as Jallikattu madu. They are mainly used for penning in the field and useful for ploughing.

Explanation

The food requirement for cattle should support healthy life of the animal and milk producing requirement. The feed for dairy cattle is broadly classified into two: Roughages and Concentrates.

Explanation

Roughage is a coarse and fibrous fodder. It consists of succulent feed (cultivated grass, fodder and root crops) and dry fodder (hay, straw and chaff).

Explanation

Concentrates are low in fiber and contain high level of carbohydrates, protein and other nutrients. A variety of raw materials such as Cholam (Jowar), kambu (pearl millet), ragi (finger millet), rice bran, wheat bran, cotton seed cake, mustard cake, linseed cake, groundnut cake, mango seed, neem cake and yellu (sesame) cake can be used to make concentrate feed. They should also be fed on green fodder (maize, lucerne, berseem, and millet and elephant grass).

Explanation

Dairy cattle need balanced rations containing all nutrients in proportional amounts and food additives which contain minerals, vitamins, antibiotics and hormones to promote the growth of animals, good yield of milk and to protect them from diseases.

Explanation

The daily average feed ratio of a milking cow is: 15-25 kg of roughage (dry grass and green fodder), 4-5 kg of grain mixture, 100-150 liters of water.

Explanation

Dr. Verghese Kurein was the founder of National Dairy Development Board (NDDB) and was called the Architect of India’s Modern Dairy Industry and the Father of White Revolution. 

Explanation

Operation Flood or the White revolution started in the year 1970 and was aimed to create a nationwide milk grid. It was a rural development program initiated by NDDB – National Dairy Development Board of India

Explanation

NDDB designed and implemented the world’s largest dairy development program called OPERATION FLOOD. Operation Flood Program is based on dairy commodity aid to increase milk supply in urban areas.

Explanation

Intensive Cattle Development Program: It is based on cross breeding of indigenous cows with exotic (European) breeds to increase milk production. New methods and modern equipment’s are made available for machine –milking of cows.

Explanation

Aquaculture is the rearing of economically important aquatic organisms like fishes, prawns, shrimps, crabs, lobsters, edible oysters, pearl oysters and seaweeds under controlled and confined environmental conditions using advanced technologies.

Explanation

Aquaculture is classified into: Freshwater aquaculture, Marine water aquaculture (Mariculture)

Explanation

Freshwater aquaculture: The rearing of aquatic organisms in freshwater is called freshwater aquaculture. Culture of organisms is carried out in pond, river, dam, lake and cold water. These freshwater resources remain within the land.

Explanation

Tilapia, carps (Catla, Rohu, and Mrigal), catfishes and air breathing fishes are cultured in freshwater.

Explanation

Tamil Nadu is a leading state endowed with rich fishery resources from Marine, Inland and Coastal Aquaculture. The marine fisheries potential of the state is estimated at 0.719 million tonnes. The inland fishery resources have a potential to yield 4.5 lakh metric tonnes of fishes. 

Explanation

Tamilnadu ranks sixth among the maritime states in coastal farming.

Explanation

Marine water aquaculture: The cultivation of aquatic organisms is in sea water. This is also referred as Mariculture or Sea farming. 

Explanation

Culture of organisms is carried out along the sea coast (inshore area) and in deep sea. Organisms like shrimps (marine prawns), pearl oysters, edible oysters, mussels and fin fishes like salmons, sea bass, milk fishes and mullets are cultured in marine water.

Explanation

Aquaculture aims at blue revolution. It is a major source of export and foreign exchange earnings for the country. It generates employment through fish farming in rural and under developed area.

Explanation

Pisciculture or Fish culture is the process of breeding and rearing of fishes in ponds, reservoirs (dams), lakes, rivers and paddy fields. It is the farming of economically important fishes under controlled conditions.

Explanation

Extensive fish culture: Culture of fishes in large areas with low stocking density and natural feeding. Intensive fish culture: Culture of fishes in small areas with high stocking density and providing artificial feed to increase production. Monoculture: It is the culture of single type of fish in a water body. It is also called mono species culture. Polyculture: It is the culture of more than one type of fish in a water body. It is also called composite fish culture. Integrated fish farming: It is the culture of fishes along with agricultural crops or animal husbandry farming. Rearing  of fish along with paddy, poultry, cattle, pig and ducks.

Explanation

Fish farm requires different types of pond for the various developmental stages of fish growth. 

Breeding pond: Healthy and sexually mature male and female fishes are collected and introduced in this pond for breeding. The eggs released by the female are fertilized by the sperm and fertilized eggs float in water as frothy mass.

Hatching pits: The fertilized eggs are transferred to hatching pits or hatching hapas for hatching.

Explanation

Nursery ponds: The hatchlings are transferred from hatching pits after 2 to 7 days. The hatchlings grow into fry and are cultured in these ponds for about 60 days with proper feeding till they reach 2 – 2.5 cm in length.

Explanation

Rearing ponds: Rearing ponds are used to culture the fry. The fish fry are transferred from nursery pond to rearing ponds and are maintained for about three months till they reach 10 to 15 cm in length. In these rearing ponds the fry develops into fingerlings.

Explanation

Stocking pond: The stocking pond is also called as culture pond or production pond. These ponds are used to rear fingerlings up to the marketable size.

Explanation

Freshwater cultivable fishes: Indian major carps (Kendai) – Catla, Rohu, Mrigal, catfishes (Keluthi), Murrels (Veral) and Tilapia (Jilebi kendai) are cultured in freshwater.

Explanation

Marine water cultivable fishes: Sea bass (Koduva), Grey mullet (Madavai) and Chanos chanos (Milk fish) are the fishes cultured in marine water.

Explanation

Fat soluble vitamins A, D and water soluble B-complex vitamins like pyridoxine, cyanocobalamine and niacin.

Explanation

One of the most economically important shell fish resources of India are prawns. They are of great demand both in the local and international market. Due to their great taste, they are a cherished delicacy to be served as food. In view of their popularity and marketing avenues in foreign countries there is a need for developing advanced technology and intensify prawn culture in India.

Explanation

A number of species of prawns of different sizes are found distributed in water resources. Only those prawns which are good in size, weight, available in plenty and easily cultivable are commonly selected for prawn culture on commercial basis.

Explanation

Marine water prawn culture: The rearing of marine penaied prawn is called marine prawn culture or shrimp culture. Penaeus indicus and Penaeus monodon are cultured in marine water.

Explanation

The rearing of freshwater prawn is called freshwater prawn culture. Macrobrachium rosenbergii and Macrobrachium malcomsonii are cultured in freshwater.

Explanation

The methods employed for prawn culture are: Seed collection and hatchery method, Paddy cum prawn culture method. 

Explanation

Seed collection and hatchery method: The larvae and juveniles obtained by collection from natural resources (estuaries, and backwaters) or by hatchery methods (controlled breeding). They are reared and grown into adults.

Explanation

Paddy cum prawn culture: It is also called Pokkali culture. It is the oldest and traditional method of prawn culture practiced in Kerala. The low lying paddy fields along the coastal areas serve as suitable grounds for prawn culture. Prawns are cultured in these fields after the harvest of paddy.

Explanation

The awareness of organic matter and concept of sustainable agriculture is gaining importance among our farmers in the recent years to produce good quality crops. Maintenance of soil organic matter is very important for sustainable productivity and this is attained by Vermitechnology.

Explanation

Vermiculture involves the artificial rearing or cultivation of earthworms and using them for the production of compost from natural organic wastes.

Explanation

The earthworms used for vermicomposting production are Perionyx excavatus (Indian blue worm), Eisenia fetida (Red worms), and Eudrilus eugeniae (African night crawler).

Explanation

Vermicomposting: It is an important component of organic farming which can convert bio-wastes into nutrient rich organic manure by using earthworms. It feeds on the organic wastes and excretes it in digested form known as castings. The compost is generally called vermicompost.

Explanation

Vermicompost is the excreta (worm castings) which is a fine, granular organic matter formed by the decomposition of organic materials by the earthworm. It is an ideal fertilizer for the soil.

Explanation

Biologically degradable organic wastes are used as potential organic resources for vermicomposting. They are:

• Agricultural wastes (crop residue, vegetables waste, sugarcane trash)
• Crop residues (rice straw, tea wastes, cereal and pulse residues, rice husk, tobacco wastes, coir wastes)
• Leaf litter
• Fruit and vegetable wastes
• Animal wastes (cattle dung, poultry droppings, pig slurry, goat and sheep droppings)
• Biogas slurry

Explanation

Vermicomposting by Bin Method: It is the rearing of earthworms in a container or bin. The container is half filled with bedding materials such as shredded cardboard, leaves, paddy husk, chopped straw, saw dust and manure. Small quantity of soil and sand is added to provide necessary grit for the worms. The bedding material should be moistened by adding water that enables free movements of the worms. The worms are gently placed and spread evenly on the bedding.

Explanation

Organic wastes (kitchen wastes, vegetable and fruit wastes) are added which are fed by the earthworms. The bin is covered with coconut leaves or gunny bags to conserve moisture provide darkness and keep out of pests. After a period of 60 days the wastes are completely transformed into nutrient rich materials that are excreted by earthworms known as worm castings.

Explanation

Vermicompost is dark brown in color and similar to farmyard manure in color and appearance.

• It is a rich source of nutrients essential for plant growth. It makes the soil fertile.
• It improves the water holding capacity and helps to prevent soil erosion.
• It contains valuable vitamins, enzymes and growth regulator substances for increasing growth, vigour and yield of plants.
• It enhances decomposition of organic matter in soil.
• Vermicompost is free from pathogens and toxic elements.
• Vermicompost is rich in beneficial microflora.

Explanation

Apiculture is the rearing of honey bee for honey. It is also called Bee keeping. It is a profitable rural based industry. Honey bees are domesticated by farmers to produce honey.

Explanation

There are three types of individuals in a honey bee colony namely the queen bee, the drones and the worker bees.

Explanation

Queen Bee: The queen is the largest member and the fertile female of the colony. They are formed from fertile eggs. The queen is responsible for laying eggs in a colony.

Explanation

Drones: They are the fertile males. They develop from unfertilized eggs. They are larger than the workers and smaller than the queens. Their main function is to fertilize the eggs produced by the queen.

Explanation

Worker Bees: They are sterile female bees and are the smallest members of the colony. Their function is to collect honey, look after the young ones, clean the comb, defend the hive and maintain the temperature of the bee hive.

Explanation

Varieties of Honey Bee

Indigenous varieties

i) Apis dorsata (Rock bee or Wild bee)

ii) Apis florea (Little bee)

iii) Apis indica (Indian bee)

Explanation

Exotic varieties

i) Apis mellifera (Italian bee)

ii) Apis adamsoni (African bee)

Explanation

The comb of the bees is formed mainly by the secretion of the wax glands present in the abdomen of the worker bee. A comb is a vertical sheet of wax with double layer of hexagonal cells.

Explanation

Formation of Honey: The honey bees suck the nectar from various flowers. The nectar passes to the honey sac. In the honey sac, sucrose present in the nectar mixes with acidic secretion and by enzymatic action it is converted into honey which is stored in the special chambers of the hive.

Explanation

Quality of honey depends upon the flowers available to the bees for nectar and pollen collection.

Explanation

Honey bees are used in the production of honey and bee wax. Other useful products obtained from honey bees are bee pollen, royal jelly, propolis and bee venom.

Explanation

Honey is a sweet, viscous, edible natural food product. Dextrose and sucrose gives sweet taste to the honey. It also contains amino acids, B-complex vitamins, ascorbic acid, and minerals. Formic acid is a preservative in honey. Invertase is an enzyme present in honey.

Explanation

Formic acid is a preservative in honey.

Explanation

Invertase is an enzyme present in honey.

Explanation

Uses of Honey

• Honey has an antiseptic and antibacterial property. It is a blood purifier.
• It helps in building up of hemoglobin content in the blood.
• It is used in Ayurvedic and Unani system of medicines.
• It prevents cough, cold, fever and relieves sore throat.
• It is a remedy for ulcers of tongue, stomach and intestine.
• It enhances digestion and appetite.

Explanation

 One kilogram of honey contains 3200 calories and is an energy rich food.

Explanation

Honey bee visits 50 to 100 flowers during a collection trip. Average bee will make only 1/12th of a teaspoon of honey in its lifetime.
