34.1. Aim

To conduct cut out analysis of canned fruits and vegetable products.

34.2. Theory

Cut out examination of canned products is conducted to evaluate the product whether confirming to FSSAI standards or not. Canned fruit and vegetables are evaluated for presence of vacuum or pressure in the can, drained weight, total soluble solids, presence or absence of preservative, internal condition of can product contents and presence or absence of fermentation for ensuring microbiological safety.

Different crops are grown in a field. Any plant growing in a place where it is not desired competing with the main crops, has to be weeded out and such plants are called ‘weed’.

Nursery is one of the important components of horticultural crop production. Nursery is place where young crop plants are raised under intensive care for later transplanting to the field. Nurseries may be classified as follows. On the basis of the irrigation facilities, the nurseries are dry or wet nurseries.

1. Dry Nurseries: Generally such types of nurseries are observed in forestry. It is maintained without any irrigation or artificial watering. The rab nurseries of Western Maharashtra, Karnataka and Gujarat come under this category. The rab or semi-rab nurseries are made in the plantation areas on small well-burnt patches of land usually 0.01 to 0.05 ha mainly for supplying teak stumps. The seeds are sown in lines 45 cm apart just before the onset of monsoon. Normally no elaborate beds are made, no fencing is made and no irrigation is provided as compared to other nurseries.

Government initiatives are pivotal in advancing natural feed management and sustainable livestock practices across India. As natural and organic farming gain recognition for their environmental benefits, numerous national and state programs are supporting farmers in decreasing their reliance on synthetic inputs, particularly commercial livestock feed. Flagship schemes such as Paramparagat Krishi Vikas Yojana (PKVY) and Bharatiya Prakritik Krishi Paddhati (BPKP) promote integrated, low-input farming systems by offering financial aid, farmer training, and implementation through cluster-based models. These schemes often incorporate livestock integration and development of natural feed resources.
Departments under the Ministry of Agriculture and Farmers Welfare, the Department of Animal Husbandry & Dairying (DAHD), and ICAR institutions actively encourage fodder production, feed preservation, and development of indigenous feed mixtures through research, on-ground trials, and skill-building programs. For instance, the National Livestock Mission (NLM) aids in fodder seed distribution, establishment of silage facilities, and training on scientifically sound yet natural feeding techniques. Institutions like Krishi Vigyan Kendras (KVKs) and State Agricultural Universities (SAUs) contribute through extension services, field demonstrations, and technical advice on formulating natural feed, utilizing medicinal plants, and conserving feed on-farm.
In recent developments, the government has promoted Farmer Producer Organizations (FPOs) and Self-Help Groups (SHGs) to facilitate collective feed processing, shared resource use, and marketing of value-added products like organic milk and free-range poultry. Similarly, the Rashtriya Gokul Mission supports the improvement and conservation of native cattle breeds better suited for natural feeding systems.

Organic cultivation is a deep rooted cultivation tradition, which had been practiced in many parts of the world, before the advent of the practice of use of chemicals.

After the green revolution there has been exponential usage of chemicals in agriculture, right from planting to harvesting. Chemicals are used in the form of nutrient inputs or for plant protection against pests, diseases, weeds and keeping deficiencies at bay. Nevertheless, after the awareness regarding the detrimental effect of chemicals on soil, climate and human health, there has been a lot of contemplation on substituting the chemicals with the organic alternatives. Growing crops using organic inputs is known as ‘organic cultivation’. Organic cultivation is a sustainable form of cultivation where a proper balance is maintained and management of plant nutrition, pests, weeds and diseases is done in a sustainable manner, keeping the soil microflora intact and active. It does not release any chemical gases in the atmosphere, does not make the soil acidic and the soil does not lose its structure and texture. Contrary to chemical farming, where over a time period, the soil quality, texture and structure is lost, in organic practices, the soil texture, quality and structure improves over time, the plants become strong and the quality of the produce is improved. Other than organic inputs, organic farming relies on some sustainable practices like using native germplasm, crop rotations with legumes, green manuring, mulching, inter cropping, mixed cropping, incorporation of farm and animal waste compost. These simple age old practices build to organic content in the soil and elevate the soil’s efficiency to make nutrients and water to the plants. The soil microflora and earthworms become biologically active, efficient and exponentially proliferate. The goal of organic cultivation is to get maximum produce from the soil in such a manner that the soil, air and water are clean and protected.

4.1 Introduction

The energy census survey has become the basis for planning & implementation of the village development based on conventional and non conventional sources which are appropriate to the local needs. The continuous and widespread use of non commercial sources of energy in the rural area is resulting in the large scale destruction of the environment. While the rural people get non conventional fuels at almost zero private cost, the social cost for meeting their energy needs has been increasing over the year. Hence the non conventional fuels acquired a special significance in the energy context.

The rural energy problem is multi dimensional & needs to be tackled through a multi dimensional integrated approach which would include augmentation of energy supply resources, technology transfer for optimum & productive use of resources, R & D inputs in particular for developing low cost energy options for the rural poor, education & training for rural users, linkage with various rural development programmes including village & small scale industries programme and adequate institutional & financial support. The multi dimensional approach for making a village self sufficient in energy planning is illustrated in Fig.4.1.

Plants grow in the open in nature, hence are subjected to biotic and abiotic stress.

Biotic stress is due to living components such as:

Insects and pests

Nematodes, mites, snails, slugs etc.

Vertebrates like rats, birds, jackal, bats etc.

The plant experiences biotic stress when root, stem, bark, shoots, leaves, buds, flowers and fruits are damaged by the influence and activity of biotic factors.

Biotic factors Diseases

Like the pests, diseases also cause stress to plants. Diseases are caused by fungus, bacteria and virus. Sometimes the exposed part of insect eaten plant part becomes the entry pathway for fungus, bacteria and virus.

India is bestowed with varied climatic conditions and a variety of horticultural crops are produced. It is estimated that 20-30% of the produce is lost before consumption because of various reasons including improper storage and this is where the need of processing for preservation arises. There are various ways of preserving the produce and various ways to process it.

Preservation is defined as methods of extending the shelf life of the produce in its original form or in a different usable form. The basic principle of preservation involves strategies which aim at reducing the spoilage. The horticulture produce is spoiled by microbial infection or infestation. Prevention of microbial damage can be achieved by keeping the produce away from microbes, by removing the microbes, obstructing the proliferation and by killing the microbes. Infestation in the harvested fruits may lead to other microbial infection and spoilage due to rotting.

Milk revolution with change in technology is gaining attention in India. Robotic milking reduces labour and increases efficiency irrespective of large dairy farms. A typical system requires a large camera- and spray-system robot. When activated to apply the disinfectant, the robot sends a six-foot- long pipe with the sprayer under the cow. These floor-mounted robots require expensive installation into the floor of the milking parlour, as well as fencing for employee protection.

15.1 Introduction

Mechanical draining has increased broad acknowledgment, especially in Western Europe, as an approach to lessen labor on dairy ranches, increment creation per cow, and improve the way of life of dairy ranch families draining 40 to 250 cows (De Koning, 2010). The developing ubiquity of this innovation is obvious in its fast pace. In 2009, the evaluated number of automated dairy ranches overall was 8,000 (De Koning, 2010). Only 6yr later, Barkema et al. (2015) proposed that this number had dramatically multiplied to 25,000 dairy ranches around the world. The level of groups utilizing this technology is most noteworthy in Scandinavian nations and the Netherlands (Barkema et al., 2015). Broad selection in these nations proposes in any event a proportion of accomplishment in helping dairy ranchers accomplish more noteworthy work productivity and a superior way of life, yet field experience recommends that wide variety exists in the measure of work spared and in the general fulfilment of early adopters.

Onion is highly vulnerable to weed competition because of its slow early growth, shallow roots, narrow upright leaves and limited canopy development. Weeds compete for light, water, nutrients and space while also harbouring pests and pathogens. Severe infestation during the critical competition period can cause substantial yield reduction. This chapter describes major onion weeds and evaluates cultural, physical, mechanical, biological and chemical control methods. Timely planting, suitable spacing, mulching, raised beds, manual weeding, mechanical tools, herbicides and biological agents are discussed. Integrated Weed Management is recommended as a smart approach combining complementary methods to improve weed control, protect soil health and sustain onion productivity.

Chicory (Cichorium intybus L. var. sativum D.C.) plant is the herbaceous, perennial plant and supposed to have descended from the wild chicory (wild succory, blue sailors) which is often seen along roadsides with its blue flowers. The leaves are used as salads in human diet and other different purposes. They were reported to be stomachic (Baumann 1982, Franke, 1981) and their juice was used against eye disease and poisoning. The infusion of chicory was believed to be good for the liver, kidney and stomach. Initially the wild plant was used but since approximately 300 B.C., the crop was cultivated for this purpose. Beverages, soups and sauces made of chicory were reported to be used in Italy and Belgium as early in 16^th century.

For the first time, the root of chicory was used as a substitute of coffee in 1690 in Holland followed by many other countries like Sweden, France, etc. During 1806 and 1813, the cultivation and use of roasted roots of chicory as coffee substitute spread over the whole European continent. In the 19^th century, the main centres of cultivation of chicory were North-East France, Belgium, England, Russia, Holland and Australia. Subsequently it was raised on large scale in Poland, Hungary, Germany, Switzerland and India. Presently over 20% of the World’s consumption takes place in Eastern Europe, especially in Poland (6%) followed by Russia, Hungary, Romania, Czechoslovakia and East Germany. Twelve percent is reported to be consumed in South Africa, 9% in India and 2% in the United States (Clark and Macrae, 1987).

India is a leading producer and exporter of onion, but its productivity, market stability and post-harvest efficiency remain constrained. Farmers face fragmented holdings, climate uncertainty, price fluctuations, inadequate storage, technological gaps and significant post-harvest losses. This chapter reviews government programmes and policies related to financial support, irrigation, infrastructure, crop insurance, market access, farmer organizations, storage, processing and agricultural research. It also discusses export-quality requirements, grading, packaging and pesticide-residue standards. Research priorities include stress-resistant varieties and hybrids, drip irrigation, fertigation, growth regulation, sprout control and non-thermal storage treatments. Coordinated policies and technological dissemination can improve farmer income, productivity, quality and market resilience.

Population expansion, climate change, diminished rainfall, and escalating food demand are adversely affecting agriculture, resulting in alterations to crop practices. Consequently, to enhance yields and obtain precise data, it is imperative to implement modern precision farming techniques and deploy diverse sensor technologies.
• In light of the current circumstances and their adverse effects on conventional farming methods, agriculture must be conducted more wisely, employing advanced and cutting-edge technologies. This is the sole method to deliver a solution and address the incessant and expanding demands of the global population.
• Precision agriculture sensors are highly effective in agriculture as they relay data that enables farmers to monitor, enhance their goods, and stay informed about changes in the field and ecosystem.
• Advanced agricultural sensors efficiently identify animals, detect estrus, and monitor health, so enabling the isolation and treatment of ill cows through the identification, detection, and tracking of herds.
• Farmers can now utilize smart sensors in agriculture to monitor their crops remotely, assess their efficacy, manage pest infestations, and promptly implement measures to safeguard their crops from environmental threats.
• A sensor is a device that detects and reacts to specific inputs such as light, movement, pressure, temperature, or humidity, converting them into representations or signals that can be interpreted by people for further analysis and processing.
• They are frequently utilized in many applications, ranging from motion detection in security systems to temperature measurement in HVAC systems. They are also utilized in commonplace items such as smartphones, automobiles, and appliances.

Farming-based livelihood enterprises are evolving in the 21st century, significantly influenced by climate change, digitalization, and changing lifestyles. These factors converge to reshape agricultural practices, economic viability, and rural community development. Here’s an in-depth analysis of their roles in this dynamic landscape:
1. Adapting to Climate Change
• Resilience Building: Farming enterprises are increasingly focused on developing resilience against climate change impacts. This includes adopting sustainable farming practices, such as crop rotation,
agroforestry, and organic farming, which can enhance soil health and biodiversity.
• Innovative Crop Choices: Farmers are diversifying crop choices to include climate-resilient varieties that can tolerate heat, drought, and cflooding. This helps secure food supply chains and farmers’ income
against climate variability.
• Water Management: Efficient water management systems, such as rainwater harvesting and drip irrigation, are being implemented to mitigate water scarcity and improve irrigation efficiency.
