1.1 Introduction

The word ‘horticulture’ was first used in 1600’s, and is derived from two Latin words, ‘hortus’(garden) and ‘cultûra’(cultivation), and it means ‘the culture (cultivation) of garden plants’. Relf (1992) defined “horticulture as an applied science and art of growing fruits, vegetables, herbs and spices, nuts, tubers, aromatic and medicinal plants, plantation crops, mushrooms and ornamental plants which include shrubs, flowering plants and turfs stimulating minds, spirits and emotions of individuals, enriching health and wellness of communities, and linking human beings to nature and its landscaped exteriors for wellness and wellbeing”. Fruits and vegetables are nourishing and protective foods. It has been recognized that fruits are a rich source of antioxidants which protect us from dreadful diseases. Vegetables and fruits contain vitamin E, K, and  carotene in addition to minerals like zinc, copper and manganese. To meet the ever-increasing demand of the country for fruits, vegetables, tubers, spices, flowers, ornamentals etc., we must strive hard to deliver better cultivars in as many aspects as possible to the society so that human beings will be in sound health physically as well as mentally. To achieve this goal plant breeding in general, and horticultural plant breeding in particular will come to our help.

6.1 Introduction

The process by which living beings give rise to the progeny of similar kind is called reproduction. Reproduction allows both multiplication and maintenance of a genotype/line/cultivar/species. So, the process of reproduction is also called propagation, and the plant part used for this purpose is called propagule. The way progeny originate is known as mode of reproduction (also called breeding system or reproductive system). The mode of reproduction of a crop determines its genetic composition which, in turn, is the deciding factor to develop suitable breeding methods. Knowledge of mode of reproduction is also essential for its artificial manipulation to breed improved types. The methods to be adopted for multiplication and maintenance of improved cultivars are also governed by the mode of reproduction. Especially in undertaking breeding investigations with new plants the nature of reproduction must be known before efficient breeding plans can be developed. The mode of reproduction has been well established for most of our important crop species.

6.2 Mode of Reproduction

Mode reproduction in crop plants may be sexual or asexual. In sexual reproduction (also called amphimixis), specialized reproductive cells called gametes are formed by the process of gametogenesis. Fusion of the male and female gametes leads to the development of an embryo and eventually the seed. In asexual reproduction, fusion of the male and female gametes does not occur, and new plants arise from unfertilized gametes (but not from zygote), or from specialized vegetative organs such as rhizome, tuber, bulb, corm, runner, sucker, stolon, bulbil etc., or by various artificial means of propagation such as rooting of stem and root cuttings, layering, grafting, gootee, etc., or tissue culturing.

1. Fruit : Types and their Classification

Fruit:The botanical definition of fruit is a seed-bearing part of a flowering plant or tree that can be eaten as food

or

Fruits are matured ovaries plus any associated flower parts and contain the seeds of the plant. The ovary may be subdivided into two or more carpels (then termed compound ovary) each bearing one to many ovules. Individual carpels develop into sections of a whole fruit, as with citrus where each familiar segment of the fruit represents one matured carpel. If the ovary is not subdivided, then it is termed simple. The ovules will mature into seeds if fertilized. Fruit has three parts.

Botanical Name: Elaeis guineensis Jacq.

Family: Arecaceae / Palmae

Chromosome No: 32

Place of Origin: Guinea Coast of West Africa

Common Name: Oil Palm

4.1 Introduction

The cultivated oil palm Elaeis guineensis Jacq. is a native of West Africa and exists in wild, semi- wild and cultivated forms. It was introduced as an ornamental crop in 1860 and planted at National Botanical Garden, Kolkata. Research on oil palm in India started during 1960 with the establishment of a research station at Thodupuzha by the Department of Agriculture, Kerala with Dura and Tenera germplasm imported from Malaysia and Nigeria. National Research Centre (NRC) for oil palm is situated at Elur, Andhra Pradesh. Oil palm crop is one of the highest oil yielding crops among all perennial crops. It gives 4 to 6 tonnes of edible oil/ha from 3 to 25 years of its life span compared to less than one tonne of oil per ha from other cultivated oil yielding crops. This oil palm is considered as golden palm due to its high yielding capacity. Among the 10 major oilseeds, oil palm is accounted for 5.5% of global land use for cultivation, but produced 32.0% of global oils and fats output.

Botanical Name: Hevea brasiliensis

Family: Euphorbiaceae

Chromosome No: 2n =36

Place of Origin: Amazon basin in Brazil

Common Name: Rubber tree, Rubber plant, Para rubber tree

11.1 Introduction

Rubber is a fast-growing tropical tree and mainly grown for the production of latex. In 1495, Columbus was the first person to report about latex. The latex was used for rub out pencil marks and this gave the product name as rubber. The latex is used for production of various rubber products. The most important application of latex rubber was initially accomplished in the 1880s when the rubber was used for making motor cars tyres. When rubber is heated with sulphur, it retains the physical properties.

According to Pasteur statements which one of the following is true

a) Living organisms discriminate between stereo isomers

b) Fermentation

d) Both a and b

6.1 Introduction

Urbanization is now a global phenomenon, but in developing countries the implications are more pronounced. Natural growth of population, reclassifications of habitation and migration trends are important in urban population in India. The population of India, which accounts for 27 per cent of the total population, was 285 million according to 2001 census. International experience shows that the pace of urban development accelerates when a country’s urban population crosses close to 25 percent of the total population (like in India).(Kumar and Chakrabarti, 2010). 

7.1. Developing Sector in Scientific and Technological Approach of Waste Management

From the very past, many traditional practices have been put into use for waste management like landfilling, composting, and recycling, which are practiced even today. However, the boundless upsurging waste compels the modern world to modify the traditional methods or to introduce innovative techniques with the grace of technology

10.1 Introduction

The consistent process of rapid urbanization and expeditious developmental activities have severely impacted the environmental components and thereby the quality of life. With limited natural resources, individuals and societies have to learn to bring in attitudinal changes in order to accomplish environment sustainability (UNESCO). From the Book “Our Common Future” (Brundtland Report), the concept of Sustainable Development can be understood as the “development that meets the needs of the present, but does not threaten the ability of future generations to meet their own needs”. 

A disaster is any event natural or manmade which creates an intense negative impact on people goods and services and or the environment and exceeds the affected community internal capability to respond prompting the need to seek outside assistance. In other words a disaster is a serious disturbance of a community or society interfere human resources losses and impacts on economically and environmentally or disaster means simply an event has unfortunate consequences on only on human but also on whole environment. Disaster can be two types’ Natural disaster and manmade disaster.

During recent years ultrasonography has become an indispensable diagnostic modality in human and veterinary medicine because of its non-invasive nature, providing visualization of internal organs, and quick results. Birth of ultrasound took place in 1794 when an Italian biologist Lazzaro Spallanzani discovered that bats used sound waves for navigation. Since then continuous developments and advancements in the technology have made the sonography a dependable and an easily accessible diagnostic modality.

Ultrasonography is being routinely practiced in canine and feline medicine for the diagnosis of diseases of the organs and also to confirm pregnancy. Its routine use in ruminant medicine is mainly restricted to pregnancy diagnosis. Recently the potential of ultrasonography is also being explored in zoo and wild animals as well as in exotic pets. Information available in companion and other domestic animals cannot be applied blindly to zoo and wild animals.

Q. 1 Hygrophilic soils are those
(A) Which attract water       (B) Which do not attract water
(C) Which transmit water    (D) Which produce water

Soil organic matter is any material produced originally by living organisms (plant or animal) that is returned to the soil and goes through the decomposition process. At any given time, it consists of a range of materials from the intact original tissues of plants and animals to the substantially decomposed mixture of materials known as humus. Soil organic matter (SOM) is the organic component of soil, consisting of three primary parts including plant residues and living soil organisms, decomposing (active) organic matter, and stable organic matter (humus). Most soil organic matter originates from plant tissue.

Water required for irrigation of cropped land is being degraded in terms of quantity and quality due to fast increasing demand for its use. Furthermore, the soil quality and crop productivity is linked to the quality of the water available for irrigation. In general, evaluation of irrigation water quality should focus on salt content, sodium concentration, the occurrence of nutrients and trace elements, alkalinity, acidity, and hardness of the water.

11.1 Introduction

Pandas is an open-source Python Library providing high-performance data manipulation and analysis tool using its powerful data structures. The name Pandas is derived from the word Panel Data - an Econometrics from Multidimensional data.

In 2008, developer Wes McKinney started developing pandas when in need of high performance, flexible tool for analysis of data.

Prior to Pandas, Python was majorly used for data munging and preparation. It had very little contribution towards data analysis. Pandas solved this problem. Using Pandas, we can accomplish five typical steps in the processing and analysis of data, regardless of the origin of data - load, prepare, manipulate, model, and analyze.

Python with Pandas is used in a wide range of fields including academic and commercial domains including finance, economics, Statistics, analytics, etc.

Q.1 We can apply the change of origin or change of scale or change of origin and scale both to the original data in case of applying ANOVA technique to make the analysis easy and speedy.

Q.2 The conclusions drawn from ANOVA based on transformed data or original data are different.

In modern times, soil tillage has emerged as an integral part of a crop system. Soil tillage or soil surface management has been found important in alleviating soil related constraints encountered in crop production. An important effect of soil tillage on crop productivity is through its influence on soil processes, soil Soil Tillage 39 properties and crop growth. At the same time, soil tillage has its impact on the environment e.g. soil degradation, water quality, emission of green house gases from soil related processes etc.

The term pesticide includes fungicides, bactericides, nematicides, rodenticides, soil fumigants and herbicides. They cover a wide range of formulations: chlorinated hydrocarbons, organophosphates, metallic salts, acetic acid derivatives, thiocarbamates etc. They all have deleterious effects on humans, domestic animals, wildlife and plants.

In India, we have mostly two types of standards, which govern the sale of foods including milk and milk products.

These are: Legal standards and Quality standards.

Legal standards

Legal standard means the specifications or the requirements which pertain to the law of the Govt. and are set up by the Govt. to meet certain minimum requirements in terms of chemical quality (i.e. composition), bacteriological quality (i.e. hygienic quality), and labelling and packaging requirements.

In our country, legal standards are given under Prevention of Food Adulteration (PFA) Rules, 1954-1955 (which are amended from time to time). Legal standards or PFA standards prescribe the minimum requirements for all types and categories of food. These standards are consistent with the minimum quality that is attainable under Indian conditions by the majority of the farmers, producers, processors, sale agencies etc. Further, any food that does not confirm to the minimum standards laid down by the legal rulers (PFA rules) is said to be adulterated, irrespective whether anything has been added to or removed from the original food.

The food productivity increased manifolds due to high-input modern agriculture with the adoption of new technologies like high yielding varieties, farm mechanisation, increased use of fertiliser and pesticide, specialised farming practices, water resource development and improved irrigation practices, etc. The Green Revolution started in the early 1960s has led to the attainment of self-sufficiency in food grain production.

Low external input agriculture developed as a concept in the 1980s, gaining ground with the establishment of the Information Centre for Low External Input and Sustainable Agriculture in 1984 (Kessler and Moolhuijzen, 1994). Low external input agriculture developed as a response to the criticisms surrounding Green Revolution technology being neither sustainable nor feasible for many small-scale farmers around the world.

Soil is a biologically active porous medium that has developed in the uppermost layer of the earth’s crust which serves as a natural medium for the growth of plants. It is one of the principal substrata of life on earth, serving as a reservoir of water and nutrients, and as a participant in the cycling of carbon and other elements through the global ecosystem.

Conservation agriculture is an approach to managing agroecosystems for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. Food and Agriculture Organisation of the United Nations defines conservation agriculture as a farming system that promotes maintenance of a permanent soil cover, minimum soil disturbance (i.e. no tillage), and diversification of plant species.

When any beam is loaded, stresses are induced and so to calculate those stresses, shear force and bending moment acting at load or support location must be required to calculate.

Indicators are the natural or synthetic chemical compounds that are used to detect the equivalence point in a volumetric analysis where unknown compound in a solution form is quantitatively estimated with the help of a known standard solution. The equivalence point, also known as the stoichiometric end point, is the point or stage of a titration reaction where the equivalent amount of the reacting substances are mixed together, and this point is identified by monitoring the rate of change in pH, conductivity, flow of current, adsorption, fluorescence, changing of solution colour, occurrence or disappearance of turbidity, flocculation or deflocculation, etc.

Centrifugation is a technique that promotes accelerated settling of particles in a solid-liquid mixture by the application of centrifugal force. The device that accelerates the separation with the help of centrifugal force is known as ‘Centrifuge’. The centrifuge consists of a fixed base or frame and a rotating part in which the mixture is placed and is then spun at high speed.

Electrophoresis is an important separation technique for the charged molecules. Biologically important molecules, such as amino acids, peptides, proteins nucleotides, nucleic acids which carry electrical charge as they possess certain ionizable functional groups may be separated and identified from a mixture with the help of this technique. Some compounds that are non-polar in nature and do not possess any charge may be transformed to charge carrying derivatives. Thus, phosphate derivatives of carbohydrates may be separated and characterized utilizing electrophoretic techniques.

The millets are a group of highly variable small seeded grasses, widely grown around the world as cereal crops or grains for both human food and fodder. These are important crops in semi-arid and tropical regions of the world (in particular in Afro-Asian countries) due to their resistance to pests and diseases, short growing season and productivity under heat and drought conditions. Finger millet (Eleusine coracana L.) is a small seeded annual cereal which belongs to the grass family, Poaceae. 

Millets like finger millet, foxtail millet, pearl millet, sorghum millet and other small millets are the ancient super grains and nutrition reservoirs for better health. In semi-arid regions, these are the important food and fodder crops, and primarily acquiring more importance in the world. 

Designing is a creative activity. Think of fashion designers or interior decorators, who design clothes or decorate homes. Think of the people who design sports cars or bikes, or the interiors of fancy hotels or corporate offices. They take simple things like fabric, or steel, or plastic and using colors create things that are attractive, useful and a pleasure to live with. Designing a project is equally creative - selecting inputs and managing them in a certain way to achieve objectives.

Project appraisal technique gives details of cost and return of the proposed business. It involves investment of huge amount of capital. There are different project appraisal technique but the most common one is investment analysis or capital budgeting. With this, we can evaluate economic feasibility of different projects.

AGRICULTURAL WASTE: The characteristics of the agricultural waste materials make them important in respect of their use and economic value. Agricultural wastes can he put to use because (1) Farm development (improvement of soil health, soil fertility, soil physical conditions and plant protection), it is the source of energy and power, (3) it acts as animal feed and fodder, (4) it is the human food

The history of cakes traces back to ancient times where Egyptians first practiced advanced baking skills. However, the modern-day cakes are said to have evolved in Europe around mid of 17th century. Today cake products and its derivatives are widely found all around the world. Cakes are sweet baked products rich in sugar, fat and egg with a tender bite and a pleasant flavour. They are basically protein foams, stabilized by gelatinized starch. Quality of cake depends on number of factors like selection of ingredients, balancing of recipe, optimum mixing and baking procedures. Good quality cakes are characterized by large volume, uniform crumb with fine cells and pore size.

Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.

According to the theory of production, the entrepreneur seeks to maximise his earnings. The goal of a proft-maximizing businessperson is to maximise production for a given amount of investment, or, to put it another way, to reduce expense.

Meaning of Production

Producing items and services with a market value is referred to as production in economics. It refers to the development of utilities. These services fall under the categories of form, time, and place utilities. The establishment of such utilities boosts the economy’s total production and redistribution of commodities and services. A commodity’s utility could rise for a variety of reasons.

Form Utility

If the physical form of a commodity is changed, its utility may increase. For instance, the utility of cotton increases, if it is converted into clothes. The other examples are processing of paddy into rice, wheat into four and butter into ghee.

The history of evolution reveals that life on Earth has gradually gone enriching itself by adding more and more varieties to it. A variety of organisms as of today exhilaratingly blossoms in the biosphere. The organisms are divided into three broad categories based on their distinctive characteristics, viz. plants, animals, and microorganisms. The other broad categories all the organisms on Earth are placed in are the five kingdoms, viz. Protista, Monera, Fungi, Plantae and Animalia. These kingdoms encompass living organisms based on their cell type (prokaryotic or eukaryotic), cell number (unicellular or multicellular), genetic recombination type (binary fission, asexual or sexual type), or feeding behavior or mode of nourishment (autotrophic or heterotrophic).

Industrial waste can be solid, liquid, or gaseous in type and is generated by industrial activities throughout a manufacturing process. Depending on its nature, it can be hazardous or non-hazardous. It is important to note that hazardous wastes can be ignitable, toxic, reactive, corrosive, or radioactive and can pose a threat to the environment. Industrial waste includes, among other things, paints, concrete, paper goods, sandpaper, metals and chemical solvents. Most industries face a significant problem associated with the disposal of waste. Due to the significant expenses involved, it is not feasible to collect and treat all of the waste due to the sizeable volume of waste produced by numerous businesses. As a result, especially in developing nations, the majority of industrial wastes are illegally deposited on wastelands like deserted fields

This chapter covers the main theories and academic perspectives used to study the role of different organizations in which they explain their vision, mission, object functioning, etc.

Climate and Agriculture

Soil, climate and water are three basic requirements of a crop to be grown in a particular region. Climate affects the temperature trends, seasons, length of the growing season, amount of sunlight and the seasonality of sunlight etc. A change in climate may cause recurrent droughts, floods and weather extremities that would affect the agricultural production, human livelihoods, health and biodiversity. The relationship between agriculture and climate is complex as it is dependent on climate and also plays a contributing role in emission of greenhouse gas (GHG). Greenhouse gases include carbon dioxide, nitrous oxide, methane, chlorofluorocarbons (CFCs), hydro-chlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), per fluorocarbons (PFCs) etc. , which play a significant role in climate change.

India is an agrarian country and the agriculture and allied sector is the largest employer of workforce as it accounted for a sizeable 18.8 per cent in 2021-22 in Gross Value Added (GVA) of the country (Economic Survey 2021-22).Agriculture is the primary source of livelihood for about 58% of India’s population and only the food processing industry employs about 1.77 million people (Indian Agriculture and Allied Industries Industry Report, November 2021). In the year 2019-20, gross value added by agriculture, forestry, and fishing was estimated at Rs. 19.48 lakh crore (US$ 276.37 billion). But still farming community has to face lot of hardships. The farmers are still applying chemical fertilizers on the basis of their own experiences as they don’t possess the soil heath cards. Although central government has initiated Soil Health Management (SHM) scheme to assist State Governments to set up new static Soil Testing Laboratories (STLs) and Mini Soil testing Labs (MSTLs). But it is time consuming and cumbersome process. There is great opportunity for Agri-business entrepreneurs with a commercially viable solution to farmers by development of simplified, sensor based and quick soil testing methods to test the nutrients and micronutrients.

Pomology: Pomology is a branch of horticulture that deals with the cultivation of fruit crops. When given a liberal and flexible translation, the word “pomology” means the science of fruit. The term is derived from the Latin word pomum, which means “Fruit” and the Greek term logy, which means “Science.

Fruit

“A true botanical fruit is defined as a mature or ripened ovary with or without accessory organs.” Classifcation refers to the grouping of individuals with similar identities, related in genetic make up, evolution or climatic requirements. The major units of classification are order, family, genus, sub family, species, variety/cultivars and clone or strain. All fruit crops bear flower and seed (spermatophyte) and belongs to class Angiosperm except in (Pinus gerardiana) of gymnosperm.

Most of the fruits are covered under the dicotyledonous families of Angiosperm except banana, pineapple, date and coconut which belong to monocotyledonous families e.g. Musaceae, Bromeliaceae and Arecaceae (Palmae) respectively. The families of economically important fruits include Rosaceae (all pome, stone fruits and strawberry), Rutaceae (citrus fruits, bael and woodapple), Musaceae (banana and plantain), Vitaceae (grapes and Anacardiaceae (Mango, cashew and pistachio nut, hog plum) etc.

Abstract

Non-structural carbohydrates are the primary product of photosynthesis in plants. Glucose, fructose, sucrose, and so on are examples of Non-structural carbohydrates (NSC). These are free carbohydrates having a low molecular weight that are involved in the creation of structures. Plants’ principal photosynthetic product, the NSC, is involved in metabolic processes and plays a critical role in plant functional characteristics. In a recent laboratory inter-comparison, NSC concentration measurements had very minor uncertainty due to different extraction and quantification techniques. Different techniques such as High-Performance Liquid Chromatography (HPLC), Gas Chromatography-Mass Spectroscopy (GC-MS), Near Infra-red spectroscopy (NIRS), anion exchange chromatography, chemical approaches such as the Anthorn assay approach, and certain kits are used to detect NSC in plants. This review will cover the methods for measuring NSC in plant tissues and attempting to infer its dynamics, as well as how to apply these tools to go beyond simply monitoring plant carbon connections such as “how much NSC is there and where it is located” to “under what conditions and to what extent is NSC used” to support plant function.
