Introduction

Fruits are undoubtedly God’s gift to mankind. Fruits are protective foods as they contain vitamins, minerals and enzymes, necessary for better functioning of human body and for fighting diseases. History of fruits is as old as that of Adam and Eve who ate the forbidden apple. Date palm seems to be the earliest fruit cultivated by man as early as 7000 B.C. Pomegranate is also one of the oldest fruits which was under cultivation as early as 3500 B.C. During ancient times, monks survived solely on fruits and milk giving an indication about importance of fruits and antiquity of fruits in India. India is the place of origin of mango, banana, phalsa, jack fruit, bael, aonla and a few citrus fruits whereas all other fruits are introduced from foreign countries. Litchi, loquat, persimmon, peach and sweet orange are from China; papaya, guava, sapota, avocado, custard apple and pineapple are from tropical America; and apple, plum, pear, date palm, mangosteen, strawberry, cherry, almond, walnut, apricot, grape and pomegranate are from the Central Asiatic Regions.

Fruit drop is a natural phenomenon, which occurs in most of the fruit crops. Fruit trees usually bear a large number of flowers and only a very small percentage leads to harvesting of fruits. Fruit drop occurs at various stages of maturity of fruit development. It is an adjustment of tree to its resources. Such drop is natural and beneficial to the trees and it will prevent exhaustion of the resources and breaking of branches by overbearing. The fruit drop usually takes place in definite waves or at a definite stage and those are presetting, post setting, jar drop and pre harvest drop.

The first drop i.e. presetting occurs immediately after flower opening. Usually male flowers as well as female/ hermaphrodite flowers with aborted pistil drop off at this stage.

Second drop i.e. post setting occurs a fortnight later than the first drop. This drop includes unfertilized flowers as well as some fertilized flowers drop as a result of adjustment in the trees between nutritional factors arid fruit set.

1. Introduction

India has diverse agro-climatic conditions which, widely promote the cultivation of different types of fruit crop. A wide variety of fruit crops are grown across the country such as banana, mango, citrus, papaya, guava, grapes, pomegranate, apple etc. Globally, we rank second in fruit production after China. The total area under fruit crops is 66.64 lakh ha with a production of 99.06 million Mt (Anon., 2018). However, the average productivity (13.03 t/ha) in fruit crops is quite low than other countries. Further, the per capita fruits availability in our country is 207.9 g/ day which is below than the recommended quantity of 230 g/capita/day (Anon., 2018). 

9.1. Introduction

Fruit juice and beverages generally comprise of naturally extracted juices, drinks, ready to serve (RTS) beverages, nectars, squashes, cordials and appetizers etc. These products are highly refreshing, thirst quenching, appetizing and nutritionally superior to many synthetic and aerated drinks. Fruit juice is the natural liquid expressed by pressure or other mechanical means from the edible portion of the fruit. Fruit juices are generally extracted from fruits in a number of ways, depending on their structure and composition.

The composition of juice is unaltered during preparation and preservation while for fruit beverages like drinks, squashes, cordial etc the fruit juice or pulp, sugar, acid, colour, flavour etc are mixed in appropriate proportions to a desirable taste. Apple juice, orange juice, mango squash, guava drink, pineapple juice and squash, mixed fruit drink, mango nectar etc are the commercial products available in the market.

GENERAL POMOLOGY

Word pomology: Derived from Greek word ëpomeí means ëdevelopment of fruit from inferior ovaryí and ëlogosí means ëto studyí.

Father of systematic pomology: De Candolle.

T. A. Knight attempted 1st artificial hybridization in fruit crops

Classification refers to grouping of individuals with similar identities related to genetic make up, evolution or climatic requirements. The major units are order, family, sub-family, genus, species, variety/cultivar and strain. Monocotyledonous and dicotyledonous are two major classes and most of the fruits are covered under dicotyledonous family. Different basis of classification of fruits are: Botanical; Ecological; Stem morphology; Fruit morphology; Flowering habit; Respiration rate; Photoperiodism; Shade tolerance; Drought tolerance; Soil texture and topography; Soil reaction; Soil tolerance; Horticultural; Bearing habit; Inflorescence type; pollination types; Type of self incompatibility; Type of dichogamy; Edible parts; Center of origin; Ploidy levels; Longevity of fruit crops; Fruit size and Nutrient contents of fruits.

Introduction

Functional food is a natural or processed food that contains biologically active compounds like nutraceauticals and phytochemicals which have health benefit and thus, an important source in the prevention, management and treatment of chronic diseases. For centuries consumption of fruits and vegetables has been attributed to beneficial health effects. Research studies stated that approximately one-third of cancer risk in humans could be attributed to diet. Free radical formation of reactive oxygen species (ROS) and subsequent oxidative stress have been correlated to many human disorders including those of the kidney, eye, lung, liver, nervous system, heart and cardiovascular system. Therefore, foods in our diet that can aid in prevention of these diseases are of major interest to both the scientific community and the general public. Biologically active plant chemicals including traditional nutrients have a beneficial effect on human health. Onion and garlic have received considerable attention for their healthful, functional benefits.

Onion and garlic are the most important vegetable crops grown and consumed almost all over the country. Both the crops belong to the family Alliaceae and have gained the importance of a cash crop in recent years. Maharashtra, Gujarat, Uttar Pradesh, Karnataka, Tamil Nadu, Rajasthan, Andhra Pradesh and Odisha are the major onion growing states whereas Madhya Pradesh, Gujarat, Uttar Pradesh and Odisha are the major garlic growing states. India is a leading producer of onion supporting 20.2% of the world production. Onion is grown in kharif, late kharif and rabi seasons whereas, garlic is grown in rabi season only except in Nilgiri Hills where summer crop is also taken. Onion is normally produced from seeds except multiplier onions where production is taken up vegetatively from bulblets. Garlic is produced vegetatively by planting cloves. Both the crops are rich source of bioactive compounds and have outstanding nutritive value. The nutritive value (per 100g edible portion) of onion and garlic are as follows.

Plant pathogens are known to cause yield reduction of almost 20 per cent in the principal food and cash crops worldwide (Oorke et al., 1994). These losses may be more severe when highly susceptible cultivars are widely grown in a particular region of the globe. The increased world’s population is posing a major global challenge to provide sufficient quatity of food with high quality fruits and vegetables. Nearly, 570 million US $ is now spent annually on research and development by the leading 15 agricultural Companies to combat with the important diseases of major food, fruits and vegetable crops. There are more than 150 active ingredients registered as fungicides worldwide (Mc Dougal, 1996). In the present era of intensive agriculture, fungicides play an important role in our fight against plant diseases and reduce the losses in yield and quality of farm produce. The global fungicide sale has been estimated to be $ 6.0 billion US. The cereal and vine industries of the Western European have become largest fungicide market followed by North America. However, the fungicide use is not intensive in Asia and the new world.

This article presents the historical development of fungicides, mode of their action, development of resistance to fungicides, fungicidal residue and chemical control of various diseases of horticultural and plantation crops.

A same active ingredient are available in the market with different trade name and are the product of different companies. These may also differ in their formulation and hazard class (table 7), the knowledge of which is necessary in the plant disease management in view of their effect on the pathogen, ecosystem and environment.

India is the second largest producer of vegetables in the world. Indian Council of Medical Research, New Delhi recommends intake of 125g leaf vegetables, 100g roots and 75g other vegetables/ day / adult for a balanced diet. Green leaf vegetables occupy an important place among the food crops as these provide adequate amounts of many vitamins and minerals for humans. Besides this, leaf vegetables are easy to grow and readily fit in any cropping system owing to its short duration. They are rich sources of carotene, ascorbic acid, riboflavin, folic acid and minerals like calcium, iron and phosphorus (Ramdasmurthy and Mohanram, 1984).
 
In nature, there are many greens of promising nutritive value, which can nourish the ever increasing human population. In spite of their nutritional importance, in India, leaf vegetable production is limited to kitchen gardens and market gardens due to various reasons. Although they can be raised comparatively at lower management costs even on poor marginal lands, they have remained underutilized due to lack of awareness and popularization of technologies for utilization.

7.1 Introduction

Artificial intelligence (AI) is the imitation of human intellect in machines designed to emulate human activities and cognitive functions. These machines are designed to accomplish tasks that normally require human intellect, such as learning, problem solving, perception, and decision-making (Zhang et al., 2022). Horticultural crops, including fruits, vegetables, nuts, and ornamental plants, are of paramount importance in global agriculture, as they contribute significantly to food security, economic prosperity, and environmental sustainability. Nevertheless, the cultivation of these crops poses numerous challenges for growers, such as fluctuating market demand, insufficient resources, unpredictable climate conditions, and the constant threat of pests and diseases (Nowak & Grant, 2018). In recent years, the agricultural sector has experienced a significant shift owing to advancements in Artificial Intelligence (AI) technologies (Liakos et al., 2018). AI has emerged as a powerful tool for the cultivation of horticultural crops, providing solutions for boosting productivity, sustainability, and efficiency (Shrivastava & Kumar, 2021). By utilizing AI, horticulturists can overcome the traditional challenges associated with crop management, resource allocation, and environmental sustainability, paving the way for a more resilient and productive agricultural sector (Garg et al., 2019). The integration of AI into horticultural crop production encompasses a diverse range of applications, including precision agriculture, crop monitoring and management, predictive analytics, automated harvesting, and genetic improvement (Golhani et al., 2018). These applications leverage machine learning algorithms, remote sensing technologies, and data analytics to analyze vast amounts of agricultural data ranging from soil composition and weather patterns to crop health and market trends (Araus& Cairns, 2014). Through intelligent data-driven insights, AI enables farmers to make informed decisions in real-time, optimize resource utilization, minimize waste, and maximize yields (Kamilaris et al., 2017). This technological convergence offers promising prospects for food production, enabling stakeholders to explore new avenues for growth, resilience, and sustainability in horticultural crop cultivation (Mohanty et al., 2016).

8.1 Introduction

Considering increased awareness and interest in using herbal products because of their safer nature, the world market of traditional medicinal and aromatic plants is growing at a very fast pace. The global herbal industry is projected to be worth 5 trillion US$ by 2050 (the world bank report, 2000). These resources not only provide primary health care, but also nutraceutical support for wellness. Also, it has been experienced that they may help in curing some of the deadly and painful diseases such as cancer, HIV, AIDS, rheumatism, arthritis etc. India, due to its rich heritage in use of medicinal and aromatic plants under various traditional medicinal systems, which are important source of information about plant properties and use, can become a major player in the global context and can increase its market share substantially. To achieve this, an effective, efficient, and vibrant program is required to cover various aspects of management, research, and development.

Looking forward, it is clear that traditional and western medicine have the potential for rich collaboration that benefits both disciplines. There is growing interest in this partnership, as shown by the number of international journals now dedicated to such research, such as Journal of Ethnopharmacology, Complementary Therapies in Medicine, eCAM, Alternative Therapies in Health and Medicine, and the Journal of Alternative and Complementary Medicine. Even the WHO has taken note of the rich possibilities of the future of TM, having put out such documents as ‘WHO General Guidelines for Methodologies on Research and Evaluation of Traditional Medicine’ and ‘WHO Guidelines on Good Agricultural and Collection Practices (GACP) for Medicinal Plants’. Despite this enthusiasm, there are several areas where the international community will need to focus their attention if the goal of integrating botanical medicines for the good of human health is to be reached.

The soil fertility is depleting in the current scenario of gap between nutrient removal from soil and supplies. Moreover, increase in the fertilizer prices has become unaffordable to small and marginal farmers. There is also a growing concern about the environmental hazards and its threat to sustainable crop production. Indiscriminate use of synthetic fertilizers for intensive crop production has resulted in large quantity of nutrient (particularly P) accumulation in soils which has resulted in generating a dead soil. In this context, the long term use of biofertilizers are considered to be economical, eco-friendly, more efficient, productive and accessible to marginal and small farmers over chemical fertilizers (Subba Rao, 2001). Biofertilizers mainly consists of specific living cells which supplies nutrients to plants through their root system. Microbes in these fertilizers provide nutrients to the plants by nitrogen fixation, phosphate solubilization, phosphate mobilization, and promotion of beneficial rhizobacteria (Bhat et al., 2010). Biofertilizer application improves the supply of nutrients, organic carbon, accumulation of soil enzymes, productivity, soil fertility index, economy of farmers, and maintenance of sustainability in natural soil ecosystem and horticultural crops. The production of efficient and sustainable biofertilizers for crop plants needs to be undertaken to make the biofertilizers popular and efficient. The important and specific research in future may be focused on the following aspects.

Introduction
Good Laboratory Practice (GLP) has been a cornerstone of laboratory operations, ensuring quality, reliability, and reproducibility in research and development across various fields, including pharmaceuticals, biotechnology, and environmental science. As we move further into the 21st century, the landscape of GLP is evolving rapidly, influenced by technological advancements, regulatory changes, and the increasing complexity of scientific research. This article explores future trends and innovations in GLP, delving into key areas such as automation, data management, regulatory shifts, and sustainable practices.
1. The Role of Automation in GLP
1.1 Increased Efficiency and Accuracy
One of the most significant trends in GLP is the integration of automation. Laboratory automation includes the prompt use of technology to perform tasks in a much efficient way with minimal human interventions, thus significantly increasing efficiency and accuracy of laboratory practices. Automated systems can handle repetitive tasks such as liquid handling, sample preparation, and data analysis, reducing the potential for human error.
Benefits of Automation
• Reduction of Human Error: Automation minimizes the chances of mistakes that can occur when humans perform these repetitive tasks, thereby improving the reliability of the results.
• Speed up the Research Process: For example, robotic systems can be used in drug discovery. These systems can conduct high-throughput screening, which means they can quickly test thousands of different compounds for potential effectiveness as drugs.

Technology transfer (TT) is entering a transformative phase shaped by globalization, digitization, and the growing role of start-ups in the innovation ecosystem. Traditional linear models of TT where inventions flowed from academic laboratories to industry through licensing are being replaced by dynamic, multi-directional, and collaborative frameworks. This chapter explores emerging trends that will define TT in the coming decades, including open innovation platforms, digital TT ecosystems powered by artificial intelligence (AI) and blockchain, the rise of entrepreneurial start-ups and spin-offs, internationalization of TT through cross-border collaborations, and sector-specific shifts driven by 5G, biotechnology, drones, and green energy. Drawing from global and Indian contexts, the chapter highlights how universities, governments, and industries can leverage these trends to build inclusive, resilient, and sustainable innovation ecosystems.
Three global shifts which will redefine TT
1. Digitization of knowledge: With AI, big data, and blockchain, knowledge and IP can be shared, tracked, and commercialized faster and more transparently.
2. Entrepreneurial ecosystems: Start-ups, incubators, and accelerators are replacing traditional firms as vehicles of commercialization, particularly in deep-tech and frontier technologies.
3. Globalization of innovation: Challenges such as pandemics, climate change, and food security require cross-border TT collaborations, making TT an instrument of both economic and geopolitical significance.

Introduction

Food crops like fruits and vegetables, nuts and seeds, herbs and sprouts, mushrooms and algae, flowers and seaweeds are all part of horticulture, which is also the study and practice of producing non-food crops like grass and decorative trees and plants. Growing plants is known as horticulture in Latin. For several reasons, horticulture is very significant: 

1. Crop Diversity and Nutrient Density: Horticulture is an essential part of the food production system since it produces so many different kinds of fruits, vegetables, and nuts.

2. A large number of people throughout the globe rely on this industry for their livelihood, since it is a significant part of agriculture. The commercial value of horticultural goods is typically rather significant.

Gaillardia is a hardy flowering crop appreciated for its colourful blooms and suitability for loose flower production, landscaping and ornamental purposes. The chapter introduces important Gaillardia species and hybrids and discusses their origin, genetics, botanical characteristics and commercially useful varieties. Production aspects include suitable temperature, sunlight, soil, propagation, seed sowing, nursery raising, transplanting, nutrient management and irrigation. Cultural practices such as weeding and regular removal of spent flowers are included to maintain continuous flowering. The chapter further describes important pests and diseases, including aphids, thrips, powdery mildew, smut and aster yellows. Harvesting during the early morning, cold-chain requirements and yield are also explained

Galangal is the dried rhizome or root of a plant, Alpinia galanga Linn. Willd. which grows mainly in the Eastern Himalayas and South-Western India. The plant is 1.8-2.1 meters high, and bears perennial rhizomes which are deep, orange-brown in color, aromatic, pungent and bitter. The fruits are about 13 mm long, constricted in the middle, and contains 3-6 seeds. The seeds are slightly pungent, with an aroma similar to that of the rhizome. Cut pieces of the rhizomes of this species are known as “Greater Galangal”. The rhizome of “Lesser Galangal” is smaller and reddish brown in color, and, has a stronger odor ansd taste. According to Guenther (1973) Galangal root is also known under the names of “Smaller Galangal” and “Radix galangal minoris”. The earliest reference to this spice is that of an Arabian geographer Ibn Khurdabah (869-895 AD), who included Galangal in a list of products from a country he refers to as Sila (which was undoubtedly China). Sometimes later, Plutarch made reference to the use of Galangal as a fumigating spice by the early Egyptians. In 1153, it was mentioned by Edrisi as an incoming spice into Ade, which was then the port used by the Egyptians for all Asiatic products. In his travels, Marco Polo mentions that it was produced fairly extensively in Kachanfu and Kinsai (Tonkin). Galangal is one of the spices which reached European markets relatively early, for it is mentioned along with Black pepper in the literature of the Middle Ages, where it received praise in various writings dealing with drugs, medicines etc. The source of the spice which was reaching the European market remained almost unknown until the last century, when in 1867, a plant of unknown botanical origin was discovered in the extreme south of China. The following year, Hance examined both dried and living specimens of the plant and was able to conclude that it was the same as the “Lesser Galangal” known to the pharmacists.
