1.1. Introduction

Food packaging involves enclosing the food product to ensure its safe delivery to end consumer in safe condition. Packaging is one of the integral components of the food industry. In order to maintain the basic nutritional and functional attributes of food material, they must be packaged safely. A faulty package can ruin all the efforts made to develop the food product. Selection of right packaging system and packaging material is essential to arrest the deterioration of food products from physical, chemical and biological factors. 

2.1. Introduction

The word ‘plastic’ is derived from the Greek word ‘plastikos’, which means easily shaped or molded. Plastics is defined as a random set of materials based on synthetic or modified natural polymers which can be formed by thermal and pressure treatment. It comprises of wide range of macromolecular organic compounds obtained either from alteration of natural macromolecules or polymerization of molecules of lower molecular weight.

3.1. Introduction

Paper and paper-based packaging is the traditional form of packaging used for various food products due to its various advantageous characteristics. It is less expensive, flexible, lightweight, durable, recyclable and available in various shapes, sizes and colour to meet customer needs. Hence it occupies a vast market in food packaging from primary (i.e., packaging which is first used after manufacture) to secondary (i.e. processing aids of primary packages) packaging and the production of paper has doubled in the last three decades. In the year 2020, china was the leading producer for paper and paper based packaging followed by USA and Japan (Figure 1).

4.1. Introduction

Packaging of materials protects, surrounds, and contains food products. It is necessary from processing and manufacturing stage till the final consumption through storage and handling. In 1804, Nicolas Appert, a French confectioner, discovered a method of “conserving all kinds of food substances in containers.” In 1810, the Ministry of the Interior’s Bureau of Arts and Manufactures paid Appert an ex-gratia payment of 12,000 francs on the condition that he publish the details of his process. Appert avoided the use of tinplate in his study. However, in the early nineteenth century (1810), Phillipe de Girard, a French inventor, filed a patent referring to the replacement of glass jars and bottles with tin cases. The official confirmation in the New York Evening Post on July 18, 1822 by Daggett and Kensett is thought to be America’s first offering of preserved provisions in tin cans (Bishop, 1978). Table 1 shows the evolution of metal packaging materials at various stages.

5.1. Introduction

Glass is one of the oldest packaging materials used for food. The use of glass as a packaging material dates back to 3000 BC where it was the first object to be used for containing and carrying food objects. It is made by cooling a heated fused mixture of silicates, lime and soda. It is an amorphous material in which all the constituents individually form an irregular network at microscopic level. It means it has failed to form a definite crystalline structure during cooling. Glass is defined as “amorphous, inorganic product of fusion that has been cooled to a rigid condition without crystallizing (ASTM, 2010)”. It has no definite melting point.

6.1. Introduction

Food packaging has a significant contribution in preserving the quality of the food throughout the processing and storage. The package containing food should maintain the quality of the product for the longest time under particular environmental conditions. The quality of various food and beverages decline with the passage of time and food become unacceptable to consume. The time in which food deteriorates and become unacceptable is termed as shelf-life. The degradation of quality with time under storage conditions depends upon intrinsic as well as extrinsic factors. The shelf-life study of a product provides important information to manufacturer and consumer regarding the quality of the food product throughout the storage time.

7.1. Introduction

In the modem lifestyle, people are extremely busy in their work and lack the time to cook their own foods. They mainly depend upon processed and packaged food for their nutritional intake. So it becomes essential that the packaged products should be safe, hygienic and shelf stable. To preserve the food for long duration, thermal processing is most suitable method. Aseptic packaging is a form of thermal food processing. Aseptic packaging can be defined as the filling of sterile containers with a commercially sterile product under sterile conditions and then sealing the containers so that reinfection is prevented; that is, they are hermetically sealed. 

8.1. Introduction

Food packaging’s essential functions is to protect the food from hazardous compounds, and contaminant. In order to improve the shelf life of food commodity, smart packaging like active and intelligent packaging has been developed which can monitor freshness, display information of quality, and improve food safety. More precisely, smart packaging was defined by Smart Packaging Journal as “the use of features of high added value that enhance the functionality of a product, notably mechanical, electronic and chemical features that improve safety and efficiency”. The major concerns with traditional packaging are not only shelf life of packaged food, but also the inability of packaging material to convey the important information about quality changes to both customer and manufacturer. 

9.1. Introduction

In a fast-paced world, demand for pre-cooked, fresh-like, and convenient products without preservatives is increasing. This demand has triggered the need for better alternative packaging materials for food products like MAP (Modified Atmosphere Packaging), CAP (Controlled Atmosphere Packaging), edible packaging, biodegradable packaging, etc. Packaging plays a crucial role in transport, distribution, storage, retailing, and end-use, a means of ensuring safe delivery to the ultimate consumer in sound conditions at optimum cost. It performs the functions depicted in Fig.1 for both fresh as well as processed products (Opara et al., 2007; Opara, 2009).

10.1. Introduction

When it comes to packaging, plastics are still popular because of durability, versatility, economic production, and enhanced mechanical properties. However, with growing concerns about the impact of plastics-based packaging on the environment, edible and biodegradable packaging were introduced. The application of edible and biodegradable packaging promotes renewable resources, which greatly reduces environmental concerns and fulfil the packaging requirements. The sources employed to develop edible and biodegradable packaging are mainly plant-based biopolymers like cellulose, proteins, starch, and lipid. Moreover, the properties of the packaging material are decided by the proportions of these biopolymers. Hence, selecting a food commodity to be package is equally important as selecting suitable resources for the development of edible and biodegradable packaging.

11.1. Introduction

Food packaging is the integral part of the food industry. Packaging may be defined as the enclosure of products, items or packages in a wrapped pouch, bag, box, cup, tray, can, tube, bottle or other container form to perform one or more of the following functions: containment, protection, preservation, communication, utility and performance. If the device or container performs one or more of these functions, it is considered a package. The major roles of the packaging of food are the containment and preservation of foods by protecting the food from physical, chemical and microbial spoilage. Besides, packaging performs some other functions like communication which means giving the information about the product, transportation of the food production and so on. Food products are classified as perishable, semi- perishable and non-perishable food based on the spoilage. Selecting appropriate packaging material and packaging technique for various food products like meat and poultry, fruits and vegetables, milk and milk products, bakery and confectionery and beverages is essential to maintain the quality of food product. Selection of the ideal packaging material for specific food requires prior knowledge about the packaging materials and its properties, type of the food products and specific spoilage mechanism of the particular food. Above all, from economical point of view, packaging material cost and capital for the establishment of the packaging technique also plays crucial role in selection of a particular packaging material or technique. 

12.1. Introduction

Food Packaging is a means to ensure safety and quality of food product throughout storage, transportation, handling, distribution, retailing, sales and in some cases till the intended use. International trades in food are generally guided by Codex Alimetarius Commission (CAC) (A joint body of World Health Organization and Food & Agricultural Organization). CAC works in harmonization within the context of food standards, food packaging and the applied rules. The mandate of Sanitary and Phytosanitary Measures (SPS Agreement) and Agreement on Technical Barriers to Trade (TBT Agreement) is to facilitate food trades and remove restraints at possible extent. Through these agreements, member countries have provision to apply quality and safety measures to safeguard the consumer. Such measures extend to every aspect of food and its packaging. On the other side, food packaging industries also progressed with sound technological advancement and sophistication in the last three decades. Innovations in food packaging attracted consumers due to convenience, availability, safety, quality and preservation throughout shelf life of the food product. 

13.1. Introduction

Any written, printed, or graphic matter that is present on the label and serves the purpose of promoting the sale of any product is known as food label (WHO). It is believed in general that food packaging and proper labelling plays an important role in food safety as it gives information regarding allergens present, manufacturing site, expiry date, nutritional information etc.

Consumption of unhealthy diet leads to many non-communicable diseases. Therefore, it is the responsibilities of food manufacturers and regulating bodies such as FSSAI and BIS to work hand in hand to provide safe and healthy food to the consumers. Labelling is an important tool useful to disseminate nutritional information to the consumers. Labelling promotes healthy eating among consumers and gives them an option at the time of purchase to choose healthy food. Information in labelling the enables consumers to choose appropriate food according to their diets and lifestyle (Grunert and Wills, 2007). In addition, the information related to nutritional content of the food must be present in such a way that it well understood by every consumer (Wills et al., 2009).

14.1. Introduction

There is a tremendous need to change the way society produces, and consumes materials to manage the environmental effect in the growing scarcity of resources. To overcome this issue, recycling process could be a great possibility that reduce the uses of natural resources, maximizethe waste utilization and produce least environmental impact. Unfortunately, packaging materials contribute 40% of solid waste in Western Europe, and 33% in US. In fact, packaging waste is likely to increase in transitioning and developing countries. Recycling process consists of collection, sorting, recovery, and management of packaging materials. As per the report of “Eurostat statistics in 2018”,European Union (EU) generates 174.1 kg of packaging waste per inhabitant, Croatia contributes 67.8 kg per inhabitant and Germany produce 227.5 kg per inhabitant.

Biosecurity refers to the measures aimed at preventing the introduction and/or spread of harmful microorganisms to animals and plants in order to minimize the risk of transmission of infectious disease. Biosecurity is of growing interest as a result of developments at the international level, including globalization of the world economy, technological progress and the rapid increase in communications, transport and trade. Against this background, there is concern that the appropriate level of protection of human, animal and plant life and health is not being maintained as risks increase. Biosecurity is a strategic and integrated approach that encompasses the policy and regulatory frameworks for analyzing and managing relevant risks to human, animal and plant life and health, and associated risks to the environment. 

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems. Invasive species threaten and can alter our natural environment and habitats and disrupt essential ecosystem functions. Invasive plants specifically displace native vegetation through competition for water, nutrients, and space. Once established, invasive species can reduce soil productivity. The negative effects of invasive alien species on biodiversity can be intensified by climate change, habitat destruction and pollution. Isolated ecosystems such as islands are particularly affected. Loss of biodiversity will have major consequences on human well-being.

3.1 Biowarfare

Biowarfare, also known as Biological warfare or germ warfare, is the use of biological toxins or infectious agents such as bacteria, viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed “bio-weapons”, “biological threat agents”, or “bio-agents”) are living organisms or replicating entities (like viruses, which are not universally considered “alive”). Entomological (insect) warfare is a subtype of biological warfare.

Offensive biological warfare is prohibited under customary international humanitarian law and several international treaties. 

Forecasting and warning systems for pests and diseases play an important role in Integrated Pest Management (IPM) and in farm advisory work. Forecasting pest outbreaks during the growing season and applying control measures only when necessary is very important in conventional farming, but also in organic farming, to increase profitability while, at the same time, minimising negative effects on flora, fauna, and groundwater (Sigvald, 2014). Number of disease-warning systems have been developed and validated for dozens of crops. A few are in wide use by growers, and represent encouraging success stories in IPM. Most warning systems, however, have not made the transition from scientific validation to real-world application. his implementation shortfall is not limited to diseasewarning systems, but also characterizes most other types of agricultural decision support systems (DSSs), whose rate of grower adoption is widely perceived as disappointing (Mark L. Gleason et.al., 2008). 

Pest resurgence is defined as the rapid reappearance of a pest population in injurious numbers following pesticide application. Use of persistent and broad spectrum pesticides that kills the beneficial natural enemies is thought to be the leading cause of pest resurgence. However, resurgence is known to occur due to several reasons, for instance, increase in feeding and reproductive rates of insect pests, due to application of sub lethal doses of pesticides and sometimes elimination of a primary pest provides favorable conditions for the secondary pest to become primary pests (Harsh Garg, 2014). There are several pesticide induced pest outbreaks reported in walnut, hemlock, cotton and soybean. Among these, brown plant hopper in rice cultivation has gained a major importance in Asian countries. In general, natural BPH populations were kept under check by natural enemies including mired bugs, ladybird beetles, spiders and other pathogens. Pesticides, however, not only have destroyed the natural enemies, but have influenced the fecun

The concepts of biosafety and biosecurity are central to efforts to protect human health against the risks posed by exposure to hazardous biological agents. Biosafety, a term used to describe the collection of technologies, processes and practices a term used to describe the collection of technologies, processes and practices aimed at preventing the unintentional exposure to biological agents, has in particularaccrued increasing importance in recent decades as a result of the trend towards globalization and concomitant growth in international communication, transport and trade (WHO, 2020). In this international context, the outbreaks of highly-infectious diseases that have occurred in the last years serve to underscore the urgent need for effective prevention and detection and response to biological risks, in accordance with the International Health Regulations (IHR).

International Standards for Phytosanitary Measures (ISPMs) are standards adopted by the Commission on Phytosanitary Measures (CPM), which is the governing body of the International Plant Protection Convention (IPPC). The first International Standard for Phytosanitary Measures (ISPM) was adopted in 1993.

As of March 2021, there are 44 adopted ISPMs (ISPM 30 being revoked), 29 Diagnostic Protocols and 39 Phytosanitary Treatments. These international standards protect sustainable agriculture and enhance global food security, protect the environment, forests and biodiversity and facilitate economic and trade development. International Standards for Phytosanitary Measures are prepared by the Secretariat of the International Plant Protection Convention as part of the United Nations Food and Agriculture Organization’s global programme of policy and technical assistance in plant quarantine. 

8.1 Pest Risk Analysis

Pest Risk Analysis (PRA) is a form of risk analysis conducted by regulatory plant health authorities to identify the appropriate phytosanitary measures required to protect plant resources against new or emerging pests and regulated pests of plants or plant products. Specifically pest risk analysis is a term used within the International Plant Protection Conventions (IPPC) (Article 2.1) and is defined within the glossary of phytosanitary terms as “the process of evaluating biological or other scientific and economic evidence to determine whether an organism is a pest, whether it should be regulated, and the strength of any phytosanitary measures to be taken against it. In a phytosanitary context, the term plant pest, or simply pest, refers to any species, strain or biotype of plant, animal or pathogenic agent injurious to plants or plant products and includes plant pathogenic fungi, bacteria, fungus-like organisms, viruses, nematodes and virus like organisms as well as insects, mites and weeds.

9.1 Geospatial Technology

It is an organized collection of computer hardware, software, geographic data, and personnel. It is designed to efficiently capture, store, update, manipulate, analyze, and display geographically referenced information. It includes typical Geographic Information System (GIS) software packages (ArcGIS, ArcExplorer, MapPoint, Google Earth), Remote Sensing (Collecting and interpreting information about the environment from a distance using satellite imagery, radar, or aerial photography), Global Positioning Systems (GPS) (A system of radio-emitting and receiving satellites used for determining positions on the earth) and many others (Lisa Kennaway, 2009). Geospatial technology can be used in pest monitoring and detection, data visualization/query, survey data collection, management and analysis, risk and pathway analysis, change detection and many others.

The term “plant pest”, mainly applied to insect micropredators of plants, has a specific definition in terms of the International Plant Protection Convention and phytosanitary measures worldwide. A pest is any species, strain or biotype of plant, animal, or pathogenic agent injurious to plants or plant products. Worldwide, agricultural pest impacts are increased by higher degrees of interconnectedness. This is due to the increased risk that any particular pest problem anywhere in the world (as a system) will propagate across the entire system.

11.1 Agroterrorism

‘Agroterrorism’, also known as ‘agriterrorism and agricultural terrorism’, is a malicious attempt to disrupt or destroy the agricultural industry and/or food supply system of a population through “the malicious use of plant or animal pathogens to cause devastating disease in the agricultural sectors”. It is closely related to the concepts of biological warfare, chemical warfare and entomological warfare, except carried out by non-state parties. It refers to a hostile attack towards an agricultural environment including infrastructures and processes in order to significantly damage national or international political interests.

The terms ‘agroterrorism, agroterror and agrosecurity’, were coined by veterinarian pathologist Corrie Brown and writer Esmond Choueke in September 1999 as a means to spread the importance of this topic.

The biosecurity risk assessment informs the biosecurity plan, which documents the mitigation measures put in place to address risks. Risks that fall outside of the risk tolerance threshold should be controlled through additional or enhanced mitigation measures. A cost-benefit analysis can assist in determining the mitigation measures in which to invest. Financial constraints and resource limitations may present challenges when looking to manage unacceptable risks. As a starting point, senior management may choose to initially focus mitigation measures on the most consequential risks and then control remaining risks as resources become available. In other instances, if the risks are determined to be too high or costly to mitigate, the organization’s project or program may need to be modified or cancelled. Recommendations for mitigation measures should be documented in the final report of the biosecurity risk assessment.

13.1 Biosafety

Biosafety is the prevention of large-scale loss of biological integrity, focusing both on ecology and human health. These prevention mechanisms include conduction of regular reviews of the biosafety in laboratory settings, as well as strict guidelines to follow. Biosafety is used to protect from harmful incidents. Many laboratories handling biohazards employ an ongoing risk management assessment and enforcement process for biosafety. Failures to follow such protocols can lead to increased risk of exposure to biohazards or pathogens. Human error and poor technique contribute to unnecessary exposure and compromise the best safeguards set into place for protection. The international Cartagena Protocol on Biosafety deals primarily with the agricultural definition but many advocacy groups seek to expand it to include post-genetic threats: new molecules, artificial life forms, and even robots which may compete directly in the natural food chain.

The Cartagena Protocol on Biosafety entered into force on 11 September 2003. It is a legally binding international agreement under the United Nations’ Convention on Biological Diversity (CBD).

What is a protocol ?: A protocol is a binding international instrument, separate from, but related to, another treaty. It is a separate instrument, that must be individually negotiated, signed and eventually ratified. It is only binding on States that become parties to it. It thus has its own parties, and creates separate rights and obligations for them, as any other treaty.

The unique characteristic of a protocol is that it is related to a ‘parent’ treaty, through substantive, procedural, and institutional links. Most importantly, a protocol under a specific treaty must comply with the parent treaty’s provisions authorizing and regulating the adoption of protocols under its auspices. 

Genetically engineered crops refer to alterations in the genetic makeup of the crop by introgression new traits such as herbicide tolerance, virus resistance, drought, flood and frost resistance, delay in maturation time of the crop and increased crop yield. They can be made resistant to pests and diseases which can significantly reduce the consumption of insecticide. Biodiversity is the feedstock for biotechnology industries. The issues relating to the Genetically Modified (GM) Foods have generated intense public debate in many parts of the world. Even though the issues under debate include the costs and benefits of the GM crops and the inherent safety concerns, the outcome of the debate differs from country to country, depending on its geographical location, strength and resilience of the farm sector, attitudes of people towards food, and so on (Anonymous, 2009). In India also, this debate has engaged the attention not only of the Government but also of the farming community and the civil society.

A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out routine operations. SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations. The military (e.g. in the U.S. and UK) sometimes uses the term standing (rather than standard) operating procedure because a military SOP refers to a unit’s unique procedures, which are not necessarily standard to another unit. The word “standard” can imply that only one (standard) procedure is to be used across all units. The term can also be used facetiously to refer to practices that are unconstructive, yet the norm. In the Philippines, for instance, “SOP” is the term for pervasive corruption within the government and its institutions.

History of plant propagation

The propagation of plants is one of the absolutely necessary occupations of human beings since time immemorial. Civilization might have started when ancient man learned to plant and grow different kinds of plants, which fulfilled the nutritional and other allied needs of human beings and their animals. Cultivated plants commenced mainly by direct selection from wild species (e,g., lima bean, barley, tomato, and rice), hybridization between species, accompanied by changes in chromosome number (e,g., strawberry, pear, and prunes), and a group of plants occurs naturally as rare monstrosities (e,g., cabbage, broccoli, and brussel’s sprouts).

Introduction

Apomixis is a phenomenon in which there is development of seed without fertilization or sexual fusion. Embryo develops without fertilization in apomixis. Hence, apomixis is an asexual means of reproduction therefore the genotype of plant will be same as of mother plant. Apomixis was first time discovered by Leuwenhock in 1719 in citrus whereas the term apomixis was first time used by Winker in 1908.The main benefit of apomixis over sexual reproduction is the selection of individual plant with superior characters and propagation of clonally through seeds. Higher plants commonly exhibit apomixis. There are more than 300 species belonging to 35 families that exhibit apomixis. Most commonly, it occurs in Gramineae, Compositae, Rosaceae, and Rutaceae.

“The light of unconditional love awakens the dormant seed potential of the soul helping them ripen, blossom and bear fruit, allowing us to bring the unique gifts that are ours to offer in this life”

–John Wehwood

Introduction

In nature and in humans, seeds are vehicles for spreading new life from place to place. In plants, it refers to the unit of dispersal that survives between seed maturation and its establishment as a seedling. A seed, like a fortress, protects and sustains life as they are well-stocked with special food supplies to endure long sieges. There are many things that seeds are, but above all else, they are the means of survival of their species. It is a way of suspending embryonic development and then resuming it years later after the parents have passed away.

Seed quality is the possession of seed that is genetically pure and physically homogeneous, coupled with health and wellness.

A seed is the first genetic material that becomes the basis for future agriculture and seeds are the basic building blocks of agriculture. A great deal of farming has been modernized by technology, but without a regular and steady supply of high quality seed, yields would be drastically reduced and crop quality would decrease as well. The production of horticultural and agronomic crops depends largely on quality seed. For farmers, seed characteristics such as genetic purity, germination percentage, vigor, and appearance have a significant effect on yield. Every professional seed producer strives to achieve and maintain high seed quality.

Introduction

Multiplication of plants is termed as propagation. Nowadays, propagation practice has been totally modernized. Propagation practices have advanced from field to in-vitro. Starting from scion stick of 15 to 20 cm length, the plants are multiplied even using cell, tissue and embryo. In modern horticulture trade, plant propagation is a soaring business. It is highly profitable, employment generative, recreative and creative business.

Several improvements have been noticed over the period of time in the basic techniques of plant propagation, using either conventional or tissue culture approaches. The propagation under protected environment by creating artificial conditions such as light, temperature and humidity under controlled irrigation through drip irrigation and fertigation has enhanced the potential of plant propagation and has made it possible to propagate the plants around the year.

Introduction

The term plant growth regulator (PGR) generally refers to organic compounds other than nutrients that influence plant growth and development at low concentrations. According to practical definitions, plant growth regulators are either natural or synthetic compounds applied directly to plants to alter their life processes or their structure in order to improve quality, increase yields, or to facilitate harvesting. The term plant hormone, when correctly used is restricted to naturally occurring plant substances. This fall into five classes: auxins, gibberellins, cytokinins, inhibitors and ethylene (gas). Plant growth regulators include synthetic and naturally occurring hormones.

Introduction

Among the various propagation techniques, plant propagation through tissue culture has gained immense importance over the years and for a few crops it has become the major method of propagation. Plant tissue culture can be defined as the ability to grow and maintain the plant organs viz., embryo, shoot, root, anther, flower and their respective tissue in a culture media. While micropropagation can be defined as the development of a new plant using plant tissue culture techniques. These plants are grown under in-vitro conditions, i.e., culturing the plant in a vessel (e.g., test tube) under a controlled condition. Since, the whole process is a lab-based work, there are chances of contamination, thus, the growing condition needs to be aseptic (growing without microbial contamination).

Introduction

After the green revolution, India achieved significant strides in agricultural output, but productivity is still poor owing to climate change and the interference of old agriculture techniques. In order to fulfill the world’s food demand in 2050, global output will have to grow by 70 % (FAO, 2020). Man has devised technical techniques for growing crops round the year.

Crop propagation is a natural process that is enhanced via the use of modified and regulated settings. These conditions are altered to guarantee that the crop in question grows to its full potential. The purpose of propagation structures is to build environments that can be changed and controlled.

A nursery is a place, where seedling, saplings, trees, shrubs and other plant materials are raised and sold out for planting in gardens and orchards. The prerequisites of a successful and remunerative fruit production are the availability of true-type, healthy and good quality planting materials. Nursery is, therefore, a place where one can produce true to type plants by gaining technical skill, maintaining plants property and by careful planning. Like orchard establishment, establishment of a nursery is also at permanent venture and any mistake made initially can’t be rectified easily in the later stages. Therefore, for establishing a nursery, due care in selection of site, plants to be raised and transportation facilitation etc. must be given.

Nurserymen and propagators propagate different types of horticulture plants with seeds, cuttings, and other methods. Regardless of the medium used, an ideal medium should have the following characteristics:

1. The medium should be sufficient firm and dense to told seed or cutting or layer firmly in place during germination or rooting.
2. The volume of the medium should remain constant upon drying or wetting.
3. This medium should be able to hold and deliver an adequate amount of moisture to the seeds, cuttings or layers.

Introduction

Management is the process of successfully accomplishing tasks with and through others. It is all about having more control and getting better results as a result of having more control. Many parts of nursery administration are unrelated to horticulture in any way. Nurseries, both wholesale and retail, are frequently managed by persons who have worked in a range of sectors. Nutrient management, disease control, irrigation management, insect pest management, and marketing management are just a few of the nursery management techniques that are necessary for a successful nursery output. A nursery manager and employees who spend a lot of time for potting plants, weeding plants, or conversing with clients may discover that they do not spend enough time for managing the nursery, resulting in a loss of control. Many activities are carried out during management, such as planning - need for planting material, provision of mother blocks, land area requirements, water supply, working equipment, growth structures, and input availability. Implementation - land treatment, biotic interference and soil erosion prevention, correct layout, input supply, and so forth. However, in a small nursery where several jobs are required, the manager must strike a delicate balance between the numerous responsibilities. Managers who are well informed can provide good management; thus, the first duty of every manager is to become knowledgeable about the company for which they are responsible.

Introduction

Nursery is an art of raising and selling seedlings, saplings, and other planting materials for use in gardens and orchards. The availability of true to type, healthy and high quality planting materials is a must for a successful and profitable fruit production. “Scion block” refers to trees planted to provide scion wood for propagating nursery stock, whereas “seed block” refers to the planting of registered seed trees that will provide seeding rootstock for propagating certified nursery stock. It consists of planting self-rooted mother trees/mother stools with the objective of providing vegetatively propagated (clonal) rootstock for the multiplication of certified nursery stock.

1. Determination of qualitative nursery planting materials

1.1 Quality assessment of seedlings

Nursery is a place where young/infant seedlings are kept under intensive care until they are ready for planting. The production of quality seedlings begins with the collection of quality seed, nursery establishment, and after-germination maintenance. The quality of plant propagation structures may not be a qualitatively gradable criterion, but it can be indirectly assessed by their relationship to growth, productivity, and vigour. The Dickson Quality Index (DQI) is very useful for assessing the quality of a specific group of seedlings. This is done by selecting some seedlings at random from that group and computing Dickson Quality Index (DQI).

The main purpose of establishing a nursery is to supply plants whether to one’s own garden or to out station indentors to fetch good income. To obtain adequate returns on the investment made by a nurseryman, one should have fair idea about lifting, packing and storage of the nursery plants.

Lifting of nursery plants

The plants grown in the nursery are to be lifted for establishment at their permanent place or for sale purpose. The careless lifting may affect adversely the establishment of nursery plants. For getting higher rate of success of evergreen plants in the field, it is always advisable to lift the saplings with a ball of earth intact particularly for mango, guava, citrus and litchi etc. However, the deciduous plants like peach, grape, apple, kiwi fruit, hazelnut, pecan nut, cherry, almond, walnut etc. can be lifted bare rooted during dormant conditions. If possible, it is advisable to irrigate the nursery 3-4 days before the actual date of removing the plants in order to prevent root damage. 

Introduction

The nursery is an area where tender seedlings are raised and conditioned before planting out in transplant beds or directly in the field. The increasing demand for quality planting material has up stepped the nursery business in many countries. The sophisticated technology, research and novel production approaches has transformed the traditional horticultural nursery to a technology intensive business. The tools and accessories associated with nursery production helps in aiding productivity of the nursery. The colour-coded and labelled plant materials, textured pots etc. are fascinating to consumers, indirectly increasing the salability of the plants and profitability of the enterprise. 

Introduction

The nurseryman needs some records if he is going to plan for remunerative returns and establish himself as a reputable business. Ideally, a nursery planner should be able to estimate how long it takes to lift saplings or how much seed is required, or how many cuttings he can accommodate in a glasshouse, as well as how much scion wood is required for grafting a particular plot. In nurseries, specific registers must be maintained to keep track of day-to-day activities, such as pedigrees and operations. In case of large nurseries, these records are required by law to satisfy inspection authorities, calculate taxes, detect theft, or discourage it.

Agriculture is under increasing pressure to produce more food, feed, and biofuel from limited land resources. The current over-reliance on a few key staple crops causes a variety of agronomic, ecological, nutritional, and economic issues and is likely unsustainable in the long run.

Vegetables have a high commercial value in general and hence contribute significantly to household income. Significant research, breeding, and development initiatives are necessary for a number of promising crops to transform existing local landraces into competitive cultivars with broad adaptability and high commercial prospects. India has a good genetic wealth of domesticated crops, and 600 plant species represent the diversity in vegetable crops out of 20,000 angiosperm plants; however, only one-fourth of these are used as major vegetable crops, with the rest classified as minor, underutilized/neglected, rare vegetables, lesser-known vegetables, wild edible vegetables, and so on. Access to the genetic diversity of these selected crops is required for success

Amaranth (Amaranthus spp.) is the most popular leafy vegetable grown in India throughout the summer and rainy season, and is known as chaulai in Hindi. Amaranth’s leaves and tender stems are high in protein, minerals including calcium, iron, zinc, copper, manganese, and potassium, as well as vitamins like vitamin A (carotene), vitamin C, folic acid, thiamine, niacin, and riboflavin. The leaves have a crude protein value of 20-32 percent on a dry weight basis and are commonly grown as a leafy vegetable in Southeast Asia.
