The digital age has revolutionized the way we live, work, and interact with the world around us. Digital transformation has become a crucial imperative for businesses of all sizes and industries, enabling them to not only adapt to the changing landscape but also thrive in it. (De Lucas,2021). The rapid advancement of technologies such as 5G, cloud computing, big data, artificial intelligence, IoT, and blockchain has opened up a plethora of opportunities for enterprises to enhance their operations, improve customer experiences, and gain a competitive edge. (Anjali et al, 2023). Businesses can increase their reach, automate jobs, obtain insights from data, personalize services, and streamline procedures by utilizing these technologies. They must reconsider their business models and implement more flexible and agile strategies in response to these exponential changes. (Bansal et al, 2020, Fenech et al, 2019).

4.1 Sampling and Preparation for Analysis

The determination of nutritional need of crops is an important aspect of nutrient management of any plant analysis programme. The need of fruit plants for mineral nutrients differ from those of annual crop species in a number of ways, many of which are related to the perennial nature of tree crops. In perennial tree crops, there is a need to supply nutrients both for ultimate fruit production, the fruits and the vegetative organs, which persist from year to year. The need for leaf analysis in perennial horticultural crops and forest trees has proved its superiority over soil diagnostic methods. This is essentially because of their deeper root system and the fact that nutrients supplied in one year may have its effect on both the nutrition and crop production in following years. However, it is largely being used not as an alternative method to soil testing, but as a supplement to soil testing. Results of foliar analysis are usually interpreted using the critical nutrient level (CNL) approach. Accurate interpretation of foliar analysis using the CNL approach is possible only when sampling is restricted to the same growth stage at which standard reference values have been established (Beaufils, 1971, 1973). The general purposes of plant analyses are:

11.1 Introduction

• Pest problems in fruit production has increased the cost of tree/plant protection and squeezed the profit of the fruit growers.
• In India, there are several existing or potential key pests for each fruit trees whose population densities must be kept at sub-economic levels to sustain higher per unit production at the farmers’ fields.
• During the second part of 20th century, the major emphasis was on pest control, which involved a set of actions to avoid, alternate or delay impact of pests on crops, which mainly involved pesticide application with the sole aim of eradication.
• Since horticultural crops like fruits are intensively cultivated that allow more inputs cost, the use of insecticides for the control of specific pests of a particular fruit crop has increased manifold during the last few decades. However, the toxic materials generated from chemical use in crop production has polluted the environment, because majority of them are not biologically degradable. They have harmed consumers’ and farmers’ health.
• Uses of broad-spectrum chemicals for pest control have a very negative impact on our efforts to conserve biodiversity. Because of their broad-spectrum nature of effect, it not only kills enemy insects but also useful insects like honey bees.
• The pest control option based on pesticide applications virtually eliminates the bee keeping activity.

Introduction

Rice (Oryza sativa L.) is one of the most important cereal grains in the world today and serves as a staple food source for more than half of the world’s particularly in India, China and a number of other countries in Africa and Asia. It occupies an area of about 161 million hectares at global level wi`th production of 503.8 million tones milled basis. More than 90% of the rice is produced and consumed in Asian countries. (FAO United Nation 2017).

Rice provides 21 percent of global human per capita energy and 15% of per capita protein. Although rice protein ranks high in nutritional quality among cereals, protein content is modest. Rice also provides minerals, vitamins, and fiber, although all constituents except carbohydrates are reduced by milling.

Rice commodity recognized as a supreme commodity to mankind, because rice is truly life, culture and tradition. It has its own history and religious importance in human life. India is one of the world’s largest producers of white rice. For India, like many other developing countries, the issue of feeding ever increasing population is of prime importance, this problem can be solved by maximizing agricultural production through use of high yielding varieties and adopting improved package of practices of rice crop. India is facing the challenges of food and fodder production to meet the demand of rising human and cattle population. One of the major causes of this problem is low level of adoption of improved agricultural practices by the farmers. Population www.thecropsite.com

There are three seasons for growing rice in India viz. autumn, winter and summer. The main rice growing season in the country is kharif. It is known as winter rice as per the harvesting time. The sowing time of kharif rice is June – July and it is harvested in September - October. India is an important centre of rice cultivation. The rice is cultivated on the largest areas in India. Historians believe that while the indica variety of rice was first domesticated in the area covering the foothills of the Eastern Himalayas (i.e. North-Eastern India), stretching through Burma, Thailand, Laos, Vietnam and Southern China, while the japonica variety was domesticated from wild rice in Southern China which was introduced to India. Perennial wild rice still grows in Assam and Nepal.

18.1. Introduction

Spoiled food is defined as the food that has been damaged or has undergone changes so as to render it undesirable/unacceptable/unfit for human consumption. Spoilage of processed products is mainly caused by the action of micro-organisms and due to the physical or chemical changes. The reasons for microbial spoilage include under- processing, inadequate cooling, contamination from leakage through can seams and pre-process spoilage. In under-processed cans (receiving low heat treatment) large number of micro-organisms is expected to be involved in spoilage.

18.2. Causes of food spoilage

Food spoilage or deterioration may be described as loss of weight, softening, souring, rotting, wilting, moulding or a combination of one or more forms. The major causes of food deterioration are: biotic and abiotic factors.

SUMMARY

Agriculture is the largest user of fresh water for irrigation to fulfill the increasing demand of food, feed, fiber, fuel and other need of ever-increasing population. Water availability to agriculture is characterized by declining in share with time, over exploitation, improper mismanagement, deterioration in quality as well as environment. This could be addressed using sustainable management of irrigation water. As per the Brundtland Commission report of United Nations, sustainable development is the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable water management aims to improve water productivity, availability and quality over an area.  Improved and efficient irrigation techniques and practices enhance water application efficiencies, and thereby reduction in associated damage to environment, which include water logging, soil salinity, runoff and leaching of nutrients and other chemicals polluting water sources, and over exploitation of ground water. Micro irrigation systems have been characterized to be the most efficient irrigation techniques. These have efficiencies even more than 90%, doubled water productivity with improved quality of produce, reduced runoff and leaching of nutrients and chemicals to water sources. Application of fertilizer through drip irrigation called fertigation could be adopted for efficient use and saving of fertilizer.  Fertilizer savings of 20-60% and 8-41% increase in yields of horticulture and vegetable crops has been realized through fertigation.

Introduction

Onion (Allium cepa L.) is one of the most important commercial vegetable crop cultivated extensively in India and it belongs to the family Alliaceae. It is used both in green and mature stage for salad and spice in a variety of flavoured dishes and soups Onion is liked for its flavour and pungency which is due to the presence of a volatile oil ‘allyl propyl disulphide’- an organic compound rich in sulphur. Onion bulb is a rich source of minerals like phosphorus, calcium and carbohydrates. It also contains protein and vitamin C. It is being used in several ways as a fresh, frozen, dehydrated bulbs and green bunching types. Dehydrated onion is in great demand which reduces transport cost and storage losses. Onion has got good medicinal value. It contains several anti-cancer agents which have shown to prevent cancer in animals. The beneficial compound called ‘quercetin’ present in onion has shown to be powerful antioxidant. Extracts of onion are being used in the prevention of ‘atherosclerosis’ and ‘coronary heart disease’. onion extensive culinary, dietary, therapeutic, trading, income and employment generation value. Onion is commodity of mass consumption and is grown almost all over the country mainly by small and marginal farmers (Shukla and Singh-2018).

A global review of onion area and production revealed that onion is grown in the world in an area of 43.64 lakh hectares with a total production of 873.44 lakh tons and productivity of 21.79 tons/ha. China and India are leading onion growing countries with a total production of 247.00 and 159.40 lakh tons, respectively during the year 2017. India produces around 174 lakh tons of onion annually ranking second in the world. Currently in India the production of onion 31129 million tons with the cultivated of 1914 lakh hectares in 2021-22 observed respectively. Among the different onion growing states Maharashtra tops in area and production. (https://www.districts of india.com).

Introduction
The addition of sugar in foods acts as a preservative when its concentration is above 66%. It absorbs most of the available water and restricts the availability of moisture required for the growth of microorganisms. Sugar adds value to the product by imparting sweetness as well as body to these products. When sugar is boiled with acid and fruits, it is hydrolysed into glucose and fructose, the degree of inversion depending upon the pH and duration of boiling. Because of the inversion of sucrose, a mixture of sucrose, glucose and fructose is found in products like jam, jelly, marmalade, preserves and candies.
Jams, jellies and marmalades constitute an important class of fruit products preserved by using sugar as the method of preservation. Apple jam, mango jam, pineapple jam, strawberry jam and mixed fruit jam prepared by using the pulp of two or more fruits are quite common. Similarly, guava jelly and orange marmalade are also examples of such products.
A fruit preserve is made from properly matured fruit by cooking it whole or in the form of large pieces in heavy sugar syrup, till it becomes tender and transparent. A fruit impregnated with cane sugar and glucose, followed by subsequent draining and drying is called a candied fruit (Fruit candy) e.g. petha candy, ginger candy. While candied fruit covered or coated with a thin transparent coating of sugar, which imparts to it a glossy appearance is referred to as a glazed fruit. When candied fruit is coated with sugar crystals either by rolling it in powdered sugar or by allowing the sugar crystals from glucose syrup to deposit on it, it becomes a crystallized fruit (Crystallized Candy). The use of high concentrations of sugar in these products acts as a preservative. Products like Petha candy, aonla preserve, candied citrus peels, ginger candy, ginger in syrup, bael, pineapple and carrot preserve are the commercial products in this category.

for limitation of world fresh water supply, farmland availability, salinity ingression and the pressing future need of food supply. The cultivation of salttolerant crops on saline soil and with saline waters has significant social and economic potential. It is often argued that fresh water agriculture near rivers and ponds was invented because of the need to sustain people and communities. Saline water agriculture is going to be needed for sustaining our future generations and civilization.
FROM DESALINATION OF SEA WATER TO SEA WATER AGRICULTURE
Sea water contains nearly 35000 ppm of dissolved salts. There has been great deal of interest world wide on desalination of sea and brackish water to safe drinking water. In early 1960s the young President of USA John Kennedy put forward two famous challenges for the scientists (1) Landing the man on moon and (2) Producing desalinated water at low and competitive cost. It is often said that the first challenge was met but the second one has been more difficult! With tremendous support and interest, work on desalination was taken up worldwide. Newer processes were being tried. At the Environmental Research Lab of University of Arizona and at Central Salt and Marine Chemicals Research Institute, Bhavnagar simultaneously solar powered HD (humidification – dehumidification) process of Desalination was developed and pilot plants were commissioned. It was however realized that desalinated water was costly and not easily applicable to most coastal communities, though for many countries in middle east with no alternative water source and cheap petroleum energy – it is applicable on a very large scale.

ABSTRACT

The popularity and belief in natural and herbal healthcare systems is inseparable from traditional ethos and practices in India. India has been known to be a rich repository of medicinal plants since time immemorial. Now many countries like China, Cuba, India, Sri Lanka, Thailand etc. have endorsed the official use of traditional system of Medicines in their healthcare programmes. The western system of medicine (allopathy) too has a large component of plant based drugs and most potent medicines use specific chemical constituents which in turn has generated bulk demand. A dramatic increase in exports of MAP’s (medicinal and aromatic plants) attests to global interest in their products as well as in the traditional health system. Past efforts of 27 years in agroforestry research and extension is now yielding results; Agroforestry is coming up in private as well as community lands in a big way for both subsistence as well as commercial purposes. Incorporation of medicinal plants in agroforestry will not only diversify the cropping system but will also lead to conserve and reduce pressure on medicinal plants in forest besides improving economic status of the farmers.

INTRODUCTION

Alstroemeria is still a relatively new cut flower in the world market and the interest in it is continuously growing. This increase is due to the fact that this flower crop is fairly easy to cultivate and does not require special demands. Its flowers are beautiful and have a very long vase life. It is commonly known as Brazilian Parrot lily or Peruvian lily or Incan lily or Red Parrot Beak or New Zealand Christmas Bell. In the Dutch market, it is an important cut flower and gaining popularity in the international market. Recently some efforts have been made to popularize this flower in India as cut flower and pot plants by some multinational companies. Its cultivation has been started around Bangalore, Pune and Hyderabad. Recently it has been introduced in Palampur, Solan, Srinagar and Ooty, to popularize this crop among growers for domestic and export markets. This crop can be grown successfully on the hill areas of Uttaranchal. Mid and high hill areas are very suitable for growing it. Alstroemeria is a typical greenhouse crop, but can be grown in open under mild environments with partial modifications. It is a potential, low volume and high value crop for hill horticulture.

Animal Biotechnology

Biotechnology is defined as “the application of biological organisms, systems or processes to manufacturing and service industries” (Coombs, 1984).

It is also defined as “the application of scientific and engineering principles to the processing of materials by biological agents to produce goods and services” (Coleman, 1986).

Animalbiotechnologyis the application of scientific and engineeringprinciples to the processing or production of materials by animals to provide goods and services to human kind.

What are Retrotransposons?

The presence of mobile elements, capable of moving from one region of the genome to another, has been known and thoroughly studied since the 1950’s. These elements are capable of exciding and inserting themselves from one region of the chromatin to another, through their peculiar terminal repeat regions. This process is mediated by enzymes encoded by the transposon itself.

Retrotransposons are a class of mobile elements, widespread in plant genomes, where they account for a significant part of noncoding DNA. Barley, for example, contains thousands of copies of the Bare-1 element, dispersed throughout the euchromatic regions of chromosomes and exhibiting sequence identity higher than 95% to each other.

Unlike other classes of mobile elements, retrotransposons insert into the genome via an RNA intermediate, synthesized by their own reverse transcriptase, without the loss of the parental copy. Unique sequence properties show that retrotransposons of the Ty1-copia group are close to retroviruses, and their mode of integration in the host genome is also very similar.

The number and exact point of insertion of retrotransposons may differ from one individual to another and this can be exploited to characterize individuals, varieties or species, depending on how recent the transpositional event is. Furthermore, insertion of a retrotransposon is an irreversible event, a characteristic that can be helpful when tracing an ancestry.

Sorghum is probably originated in Africa. Because of the great diversity of types grown in East Central Africa, in and around Ethiopia and Sudan, it seems probable that it originated in that area (De Condole, 1884).

This chapter introduces the principles and practices involved in the collection, processing, evaluation, storage, and management of forest seeds. It examines forest seed biology and variability, seed quality and viability assessment, seed dormancy, and methods used to overcome dormancy. The chapter also addresses seed handling, storage, pest management, certification, and the integration of seed technology with genetic improvement programmes. By connecting seed quality with successful regeneration and tree improvement, the chapter provides a foundation for producing healthy and genetically suitable planting material for forestry and conservation programmes.

Definition

Packaging is the science, art, and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of design, evaluation, and production of packages. Food packaging is packaging for food. It requires protection, tampering resistance, and special physical, chemical, or biological needs. It also shows the product that is labeled to show any nutrition information on the food being consumed

Packaging may be defined as co-ordinated system of preparing foods for transport, distribution, storage, retailing and their use. It is also a means of ensuring safe delivery of goods to the consumer in sound condition without affecting adversely the quality of the product packed in it at a reasonable cost. Packaging thus has as “techno-economic function” aimed at maintaining the quality of food stuff packed, with a view to retain the quality for a reasonable period.

Packaging plays a vital and dominant role in marketing, in maintaining quality and in preserving the food.

Consequent to the increase in the consumer awareness of the healthy hazards, which may be posed by different types of packaging material. It becomes inevitable for the packers to use better quality, hygienic packaging material which could retain the quality of the product for a longer time without posing any health hazard. The choice of a suitable packaging becomes all the more necessary for a number of factors like physico-chemical characters and acceptability of the commodities packed in any packaging material. Apart from this the package should be of the right shape and size and must attract the consumer's eye which could offer an absolute confidence regarding the wholesomeness of the products pack in it.

INTRODUCTION

Anthuriums are a perennial herbaceous plant of great beauty and grown either for their showy cut flowers or for their attractive foliage. They are valued for their colourful long lasting spathe and spadix. The cultivars contribute elegance and attractiveness, which are pre-requisites for quality and floral design. It is also known as Flamingo flower or Flamingo lily. What is usually considered the flower is comprised of a colourful, modified leaf (spathe) and hundreds of small, botanical flowers on the pencil like protrusion (spadix) rising from the base of spathe. Anthurium have been cultivated from many decades for cut flower production. Since the mid 1980’s its popularity has increased dramatically and has now become a popular addition to many foliage growers. The economic life span of anthurium is around 6-8 years.

In India the cut flowers of Anthurium andreanum are cultivated for considerable length of time although still in small scale. Commercial viable production should be estimated of approximately 5 ha, which is far below the market demand. The anthurium is getting increasing popularity in the Indian market and therefore, most of the locally produced anthurium is sold in the domestic market against reasonable prices. Its export possibility appears very promising as the flowers are already exported to the Middle East. The development of main flower distribution centre in Dubai offers important possibilities for Indian floriculture.

Introduction

Food supply is a major concern in the near future as the human population touches 9 billion in 2050 and therefore, more food has to be produced. This has to be achieved in the face of climate change amounting to constant pressure of biotic and abiotic stresses. However, Swaminathan (2007) opined that science and technology can play a very important role in stimulating and sustaining an evergreen revolution leading to long-term increases in productivity without associated ecological harm. Rice is considered as global grain since it is consumed by more than half of the world population. In India rice supplies calorie requirement to more than 70 per cent of its population. This is evident from the fact that rice is cultivated in all the 30 states and 5 union territories of the Indian subcontinent of diverse ecologies ranging from below sea level to mountainous regions. Though India tops in rice acreage (43.61 mha) its productivity of 3.19 t/ha (rough rice) is far below world average of 4.12 t/ha and that of Asia’s average of 4.19 t/ha (Shobharani et al., 2010). This low productivity is mainly due to unfavourable ecologies of the varied ecosystems which, rice encounters during critical stages of its growth. Salinity and submergence are major abiotic stresses, next to drought, limiting rice production in South East Asia including India.

In India nearly 8 mha are salt affected of which 2 mha are coastal saline and 3.4 mha are sodic (Singh, 1994). Rice is predominant crop in these areas especially in vast stretches of eastern and western coasts of India. The presence of salts, in excess to plant growth, in the soil solution makes the soil detrimental to crop growth. The source of the excess salt may be from soil or irrigation water. The content and composition of salts (ions) in tandem with types of soil and weather conditions prevailing during the crop period decides the severity of salt stress. Similarly, f lash floods or short-term submergence regularly affect rice growing areas in South and Southeast Asia. Even more favorable irrigated areas experience flooding problems during the monsoon season. It is also prevalent in rainfed lowlands where most of the present day rice varieties do not survive complete submergence for more than a week. In India 30% of the rice growing area is prone to such menace resulting in severe yield losses (Neeraja et al., 2007).
