Additive manufacturing is increasingly important for developing resource-efficient and customized products while reducing material waste associated with conventional manufacturing. This chapter examines the role of additive manufacturing in supporting green and sustainable production systems. It covers environmental benefits, economic and operational advantages, additive manufacturing technologies, sustainable applications, life-cycle assessment, environmental impact analysis, challenges, and design strategies. Industry trends, case studies, sustainability standards, and future research directions are also considered. In the context of green composites, additive manufacturing can support flexible fabrication and potentially improve material utilization and product customization. The chapter emphasizes the need to evaluate manufacturing technologies across their complete environmental and economic life cycle.

Motivation of staff both in private and public organizations, leads to greater effectively leading to higher productivity and better performance. Motivation is the performance or procedure of presenting an intention that leads a person to capture some accomplishment (Quratul, 2011). Veterinary institutions like other organizations also seek to achieve better performance level. This requires providing motivation as an incentive or within the veterinarian as an individual to be self-motivated. There is a good scope for veterinarians to be more committed to work. McGregor argued that management has the responsibility to ensure that the productive elements of the enterprises are organized, such as money, materials and people with the purpose of meeting economic ends. People have an inborn dislike to work and tend to avoid it whenever an opportunity arises. It is also observed that people are born selfish; indifferent to the needs of the organization; hence people’s efforts need to be directed through coercion, controlling their action and modification of their behaviors to attain organizational goals. Hence, people in the organization need to be directed to take responsibility. To achieve organizational objectives, people need to be persuaded, rewarded, coerced, controlled, directed or threatened with punishment. While another theory is opposable to it. It is believed that if vets are motivated they would reach greatest potential. As extension specialist we need to motivate our peer and farmers aiming to improve performance and increased satisfaction.

Low-temperature preservation is one of the most widely used physical approaches for extending food shelf life without seriously affecting quality. Reducing storage temperature slows microbial multiplication, enzyme activity and chemical deterioration, with inhibition increasing as temperature declines. Refrigeration maintains food above its freezing point, while freezing reduces temperature below zero and converts available water into ice. The chapter examines conventional refrigeration, advanced chilling, freezing, cryopreservation, superchilling and the influence of ice crystallisation on food quality. It explains how temperature, cooling rate and crystal size affect texture, nutritional retention and storage stability, while also addressing the limitations and quality changes associated with prolonged low-temperature storage.

Integrated fish farming, when paired with biogas production and vermicomposting, offers an eco-friendly and resource-efficient model. This system combines fish culture with livestock such as pigs or poultry, using animal waste to fertilize fishponds. This reduces dependence on chemical fertilizers and enhances fish growth. Biogas units convert manure into energy while producing a nutrientrich slurry that can serve as fertilizer. Vermicomposting further processes waste into high-quality compost, adding to the sustainability of the system.
USE OF CATTLE/PIG DUNG FOR BIOGAS GENERATION
Dung from cattle and pigs serves as an excellent input for biogas production, which can be seamlessly integrated with fish farming. Utilizing animal waste in this way improves pond fertility, increases fish production, provides clean energy, and reduces environmental strain. In India, cow dung is traditionally used directly in fishponds, yielding 1,500–2,000 kg/ha of fish. However, this output can more than double when the dung is first processed in a biogas plant and the digested slurry is used.
Method for a 0.4 ha Pond
1. Pond Preparation: Prepare the pond in June using the urea-bleaching powder method or through draining and sun-drying.
2. Stocking: Add 2,000 fingerlings (5–8 g each) of six Indian major carps—Catla (20%), Rohu (25%), Mrigal (20%), Silver Carp (20%), Grass Carp (5%), and Common Carp (10%).
3. Fertilization: Apply 30 liters of biogas slurry daily. The slurry, high in nitrogen and phosphorus, is non-toxic, unlike decomposing raw dung. Avoid application on cloudy days or when fish surface for air.

Thermal preservation is among the most established methods for improving the safety and storage life of food. It uses controlled heating to destroy spoilage organisms and pathogens and to inactivate undesirable enzymes. Processing intensity varies according to the target microorganisms, food composition, packaging and required shelf life. Pasteurisation reduces pathogenic and spoilage microorganisms without achieving complete sterility, while sterilisation destroys more heat-resistant organisms and spores to produce commercially stable foods. Ultra-high-temperature processing combines very high temperatures with extremely short treatment periods. This chapter also discusses retort processing, thermal-death kinetics and microbial-inactivation models used to design safe processes while minimising nutritional and sensory damage.

Vegetables are rich source of nutrients, vitamins and minerals. Phytochemical contents in vegetables and their strong antioxidant potential in scavergering ree radicals have generated tremendous attention among the consumers. Consumption of vegetables has significant health-promoting effect and can reduce the incidence of cardiovascular diseases, cancer, Acquired Immuno Deficiency Syndrome (AIDS) and various other degenerative diseases. Human health, in recent years, has assumed an unprecedented status. The rising population levels, increase in mental stress and changes in dietary habits have resulted in various forms of degenerative diseases including cardiovascular, cancer and ageing. As a result, there has been an alarming explosion in consumers’ interest in health. In recent past, tremendous progress has been made for increasing vegetable production in the country. India has emerged as the second largest producer of vegetables next to China. During 2000-2001, India produced 93.92 million tonnes of vegetables from 6.24 million ha of land, accounting a productivity of 15.0 tonnes/ha. During 1991-1992, total vegetable production was 58.54 million tonnes from 5.59 million ha of land, with productivity of 10.5 tonnes/ha. Thus, in last one decade country has multiplied its vegetable production one-and-a-half times. Presently, India’s share is more than 13.60%. Our country will need to produce 215 million tonnes vegetables by 2015 to meet the demand of domestic and export markets. The increase in vegetable production by increasing area under vegetable cultivation is limited due to continued decrease of land holdings. Hence, it is essential to increase vegetable productivity to fulfill country’s requirements for food and nutritional security and poverty alleviation.

Homestead is a small scale, supplementary food production system; it has the potential to produce high value crops including various spices condiments by and large for the household members. A typical home garden is an adjunct to the house, where selected trees, shrubs are grown, not only edible fruits / vegetables, but also for medicinal, ornamental, socioeconomic and ecological benefits. Homestead exhibit a multi tired canopy structure somewhat identical to the tropical evergreen forest formations. The vertical stratification provides a gradient in light and relative humidity, which creates different niches for enabling various spices/groups to exploit them .Mostly shade tolerant crops constitute the lower stratum, the shade intolerant trees the layer and spices with varying degree of shade tolerance in the intermediate strata .These multi strata system are structurally and functionally the closest mimics of natural forests yet attained The structural and floristic diversity of tropical home gardens are perhaps aided by the biophysical environment, socio-culture factors and economic consideration. 

It is tropical fruit which is commercially cultivated in humid areas of India. Fruits are very tasty, sweet and rich in sugar. Trees are ever light green, slow growing and it attains a height of about eight meters.

Origin and Distribution

Sapota is native to Central and South America, specifically from the Yucatan Peninsula of Mexico to Costa Rica, where the largest population of native trees still exists (Gilly 1943). It is now widespread throughout the tropical regions of the world, including Central and South America, the West Indies, India, and Florida in the United States.

Sapota is grown on a commercial basis in India, the Philippines, Sri Lanka, Malaysia, Mexico, Venezuela, Guatemala, and some other Central American countries. India is the largest producer of sapota fruit with current production around 24,000 ha (Chadha 1992). Sapota is widely planted in south Florida, where the fruit is marketed locally and shipped to northern and eastern U.S. markets. The fruit, however, is not commonly seen in the United States. In southern Mexico and Central America where sapodilla is native, it is considered to be one of the best of the tropical fruits.

Medicinal plants especially underutilized fruit are the nature’s gift to arid zone. Many of fruits are popular in this area but aonla posses an important place among all. Aonla or Indian gooseberry (Emblica officinalis Gaertn) is native to tropical south-eastern Asia mainly peninsular of central and southern India. The tree is known as Amla, Amlaki, Amli, Ambala, Amalakamu and Nelli in different parts of India. It is a very hardy tree and can be grown under diverse soil and agro-climatic conditions without much care. Aonla fruits has been reported to have potential of antioxidant, free radical scavenging capacity, anti-inflammatory, anti-mutagenic, immune modulation properties, which is used to cure various cancer, diabetes, liver and heart related diseases

Aonla has been regarded as a sacred tree in India. It has religious value and it is medicinally very important since ancient time. It has hallowed position in Indian medicine system called as Ayurveda as a protective remedy for several mankind problems. The tree was worshipped as Mother Earth and is believed to nurture humankind because the fruit are very nourishing. Kartik Mahatma and Vrat Kaumudi order the worship of this tree. The leaves are offered to the Lord of Shri Satyanarayana Vrata, Samba on Shri Shanipradosha Vrata and Shiva and Gowri on Nitya Somvara Vrata. The fruit and flowers are also used in worship. Fruits of aonla are processed in various forms like Juice, Murabba, Chayvanprash, candy, powder and flakes which has significant role in mitigating several malnourished disorders. Aonla cultivation has gained special attention of researcher community due to its significant role in medicinal industry as well as processing potential.

The ber is an important indigenous fruit and growing in semi arid conditions in the country. Ber is grown in China for the last 4000 years and under sub tropical to tropical as well as Mediterranean regions of the world. It is cultivated widely for its resistance to grow in drought and other diversified climatic and soil conditions, so it is also known as ‘King of fruit’ of arid.

Origin and Distribution

The origin of ber is said to be India to South-western Asia. The ber is being cultivated in Northern India, central India and peninsular India. Hisar, Rohtak, Panipat, Gurgaon, Jind, Mahindergarh in Haryana. In Rajasthan it is cultivated in district of Bharatpur Alwer, Barmer, Jodhpur, Palib and Gnaganagar Jaipur in area 82, 73, 59, 53, 53, 53,41 hectare with production 365, 395,133, 294, 340, 597, 826 metric tones, respectively. However total cultivated area in Rajasthan is 738 hectare with production 5248 metic tones under ber during 2017–18 (Anonymous, 2018).

The area Sangrur and Patiala in Punjab; Banaskantha and Sabarmati in Gujarat; Bijapur and Bellary in Karnataka; Tirunalveli, Ramanathapuram and Salem in Tamil Nadu are major ber growing areas in the country. Besides India, ber is grown in Afghanistan, Iran, Syria, Burma, Australia, USA, Russia, Italy, France, Spain and Northern Africa.

Most often, a plant gets diseased when it is harmed by an abiotic agents or attacked by a pathogen. As a result, in the first scenario, interaction and contact between the pathogen and the plant are required for the occurrence of a plant disease. No disease develops even though a pathogen and a plant come into contact if the weather is too extreme at the time of the pathogen’s contact with the plant and for a while afterwards. This could be because the plant is able to fend off the pathogen’s attack or because the pathogen is unable to attack at all. Therefore, it would appear that in order for disease to manifest, a third component—a set of environmental factors falling within a favorable range—must also exist. The degree of disease severity in both individual plants and plant populations is impacted by changes in any one of the three components, which can each show significant fluctuation. Plants can exhibit genetic uniformity over a wide area, be of a species or variety that may be more or less resistant to the pathogen, or they may be too young or too old for the pathogen to prefer. All of these factors can either accelerate or slow down the rate at which a particular pathogen causes disease. The way the three elements of disease interact has frequently been represented as a triangle (Fig. 2-1), which is commonly known as the “disease triangle.”

Pineapple (Ananas comosus L.) is an important commercial fruit crop belongs to family Bromeliaceae. It is one of the choicest fruits all over the world because of its characteristic taste and pleasant flavour. Plant is herbaceous in nature with narrow pointed leaves and 50–100 cm height. The inflorescence composed of 150–200 flowers arranged in a compact spiral cluster. The flowers are perfect with three short fleshy sepals and petals, six stamens, floral bract and ovary with three locules. The plant bears a single fruit of cylindrical shape terminally on a peduncle come out from the centre of the rosette. Pineapple fruit is a multiple or sorosis type fruit formed by the partial fusion of numerous fleshy segments from several separate flowers and edible part of fruit mainly consists of the ovaries, bases of sepals, bracts and cortex of the axis. Commercial varieties are self sterile but easily crossable with plants outside their varietal group. The apex of fruit bears a compressed, leafy and spiny shoot known as crown. The fruit weight ranged from 1.00–2.50 kg and has outer colour yellow and very golden yellow flesh inside. Pineapple fruits are mainly consumed as fresh fruit, juice purpose and also used for canning. The typically yellow fruit flesh is found suitable for fresh consumption when sweet (10 to 18% sugar) and moderately acid (0.5 to 1.6%). Fruits are processed in various value added products like pineapple chunks, crushed pineapple, diced pineapple, slices, juices, syrups, jams, etc. The pineapple possess crassulacean acid metabolism (CAM), a photosynthetic carbon assimilation pathway with high water-use efficiency

Introduction

Peach (Prunus persica (L.) is an important deciduous fruit crop in temperate regions. The basic chromosome number 8 and somatic chromosome number 16. It belongs to family Rosaceae family, subfamily Prunoideae. It has a deciduous nature and can reach heights of 5 to 10 m. It is classified with the almond within the genus Prunus in the subgenus Amygdalus that is distinguished from the other subgenera by the corrugated seed shell.

The majority opinion among botanists today is that they are Chinese in origin and were transported along the silk road in ancient times, most likely by around 2000 BC, to Persia and the Mediterranean region. Introduction of the cultivated peaches probably took place in the latter half of the 19th century.

China, Japan, Iran, Turkey, and other Mediterranean nations have historically produced significant amounts of peaches. Peaches have been cultivated in these nations for thousands of years. The United States, Canada, and Australia have all grown in importance more lately. Due to insufficient summer heat, oceanic climate regions like the Pacific Northwest and the British Isles are generally unsuitable for peach growth, though they can occasionally be grown trained against south-facing walls to capture additional heat from the sun. In the British Isles, trees can thrive in a protected, south facing location and produce both flowers and a plentiful supply of fruit.

There are many cherry species, but only a few have been domesticated. The sweet cherry trees are large (30–40 feet tall) and usually pyramid shaped. Branches grow upright. The fruits are large, have a deep stem cavity, vary in colour from light yellow to dark red to purplish black. Flowers arise from clusters of 2 to 5 flowers on short spurs with multiple buds at tips; the distal bud develops into a leafy shoot. The flesh ranges in texture from tender to firm, and is sweet. Most sweet cherries are consumed as fresh fruit. The tart cherry, is sometime called “red cherry” or “sour cherry” and may have arisen from an unreduced pollen grain of Prunus avium crossed with Prunus fruiticosa. Trees are very cold hardy, but are shorter lived than sweet cherry. The fruit is relatively small, and have higher acid and lower sugar content than sweet cherry. Tart cherries are used for processing, jam, and pie filling. The Duke cherry is a hybrid of Prunus avium and Prunus cerasus and all gradations between the two species exist, but most varieties more closely resemble sweet cherry. Sweet cherries are the variety most often found in markets. They have a thick, rich, and almost plumb-like texture. Sour cherries are not usually eaten raw, but are widely used for making preserves, candy etc. Sour cherries are much smaller than sweet cherries and all varieties are self-fertile. Cherries are cultivated all over the world and the top 3 producers of cherry are Turkey, USA and Iran. The cultivated forms are of the species sweet cherry (Prunus avium) to which most cherry cultivars belong, and the another sour cherry (P. cerasus), which is used mainly for making preserve etc. Both species originate in Europe and western Asia; they do not cross pollinate. Some other species, although having edible fruit, are not grown extensively for consumption, except in northern regions where the two main species will not grow.

The term agriculture is derived from the Latin words ager or agri meaning soils and cultura means cultivation. Agriculture is the art, science and business of crop production. It encompasses all aspects of crop production, livestock farming, fishery and forestry. Agriculture is the conversion of solar energy into the chemical energy. Crop production is the conversion of environmental inputs like solar energy, carbon dioxide, water and nutrients in soil to economic products in the form of human or animal food or industrial raw materials.

Agriculture is a science, an art and business of crop production

Agriculture is a science of farming. Scientific principles are employed to find ways of making it as efficient as possible. Through scientific principles plants and animals are transformed genetically and most favorable environment is provided to harvest higher yields of good quality with least expense of energy. The scientific principles of various branches viz. soil science, genetics and plant breeding, entomology, plant pathology, microbiology, agricultural engineering etc. were employed in agriculture. Agriculture like any other science is a body of truths synthesized and systematized and arranged in such a way as to show the operation of general laws and principles.

Agriculture is an art which embraces knowledge of the way to perform the operation of a farm in a skillful manner. The physical and mental skills are involved in agriculture. The skills may be acquired through years of experience viz. ploughing, stacking hay bundles, handling animals, sowing seeds, transplanting, driving a tractor etc. Mental skills are those involved in decision making for example when to plough the land, selection of appropriate crops, seed selection etc.

Agriculture is a business which is no longer a way of living or subsistence agriculture, where production is intended to meet the home requirements. Agriculture is intended to earn more income. Land, labour, capital are judiciously used. Like in any industry the farming industry should forecast the demand, tailor the production with demand to earn more profits. It involves processing, value addition, transportation, packing and storage in scientific way. Knowledge of employee and employer relationship or human resource management, export and imports, taxation, customs, tariffs and trade are required. All these aspects demand business knowledge in addition to the production and managerial skills. Traditional agriculture is no longer relevant for success in agriculture. Commercial agriculture or corporate farming, agribusiness development corporations demand entrepreneurs in agriculture rather than technologists alone.

Species determination in meat products is crucial for traceability and preventing fraud, especially in the buffalo meat industry, which faces significant price disparities across regions. The complex global trade networks, with many intermediaries and processing stages, increase the risk of obscured provenance and adulteration. This not only poses serious public health risks but also leads to economic losses. Thus, there is an urgent need for rapid, reliable testing methods to verify buffalo meat authenticity and detect mislabeling. Existing protein-based and DNA-based assays, including isothermal and non-isothermal amplification techniques, often lack sensitivity, specificity, practicality, repeatability, and accessibility. The present study introduces a Point-of-Care (POC) polymerase spiral reaction (PSR) assay for rapid, on-site identification of buffalo tissue, especially in resource-limited settings. The PSR method uses chemical-free snap-chill DNA extraction, highly specific mitochondrial d-loop gene primers for amplification, and unique chromogenic indicators for visual detection, overcoming the limitations of current detection methods. The effectiveness of the chromogenic indicators was validated against SYBR Green I and agarose gel electrophoresis methods. The assay showed high specificity, with no cross-amplification in common meats like beef, mutton, chevon, and pork, and sensitivity down to 10 fg of buffalo DNA. It detected buffalo meat adulteration as low as 0.1%. The assay’s accuracy was confirmed through comprehensive validation using diverse, blind, and processed samples, compatibility testing with a commercial DNA isolation kit, and comparison with standard buffalo-specific PCR. This study is the first to report a PSR colorimetric assay identifying buffalo tissue within 90 minutes in resource constrained settings.
