Introduction In today’s environment, the greatest challenge for the food industry is to develop health promoting foods; it is determined by the raw materials used and its impact on consumer health. Furthermore, people lifestyle has changed greatly, resulting in a change in food eating patterns. In today’s world, people are moving towards eating foods that are nutrient base and tasty (Bonciu, 2018). of all the nutrient based products available in market, expanded snacks have become a popular snack all over the world because of its crunchy texture and low density making it consumer’s acceptance (Grasso, 2020). The basic idea for developing any expanded snacks is utilizing a starch-based material for a better crispy and crunchy product, but to make it more nutritious incorporation of protein and fibre rich raw materials is recommended (Gu et al., 2017). Along with the raw materials, the other important parameters for developing any extruded product is the particle of the flour, its physicochemical and rheological properties of the extrudates are much concentrated (Bouasla & Wójtowicz, 2021) Thereby, extruded snack is considering as functional food with major health benefits.

5.1 Introduction

Quality is one of the major positioning tools of the commodity for marketability, profitability and for consumer satisfaction. The relative importance of each quality component depends upon the commodity and its intended use and varies among growers, handlers and consumers. To growers a given commodity must have high yield and good appearance and must withstand long distance transportation to market whereas, appearance of quality and longevity is important from the point of view of wholesale and retail marketers. Terms commonly used in measurement of keeping quality of cut flowers are longevity, shelf-life, vase-life, and lasting quality. In addition to these, several criteria have been used for evaluation of post harvest flower quality like:

Epididymal Total Sperm Count

The epididymal sperm is obtained as described above, incubated at 35°C, which is the optimum temperature of rat epididymal sperm. The epididymal f luid is then diluted to a volume of 5 mL of pre-warmed (32°C) the spermatozoa are counted by hemocytometer using the Improved Neubaur (Deep 1/10mm. LABART, Germany) chamber as described by Pant and Srivastava (2003).

Total viable cell/ml = (Average number of sperm per chamber) x 103 x (Dilution Factor)

Liveability and abnormal sperm

Per cent live spermatozoa is estimated by differential staining technique using Eosin-Nigrosin stain (NE) (Campbell et al., 1953). These slides are also used for estimating the per cent abnormal sperm morphologically on the basis of observable abnormalities of head, neck, mid-piece and trail region of the spermatozoa.

The percent live spermatozoa are determined adopting the differential staining technique using Eosin-Nigrosin stain.

• A drop of epididymal semen is taken on a clean, grease free pre warmed glass slide.

• 4-5 drops of Eosin-Nigrosine stain (1% Eosin and 5% Nigrosine in 3% sodium citrate dehydrate solution) is placed near the semen drop.

• Epididymal semen and stain are mixed gently using a blunt fine glass rod.

• After 30 seconds to 1 minute a thin smear is made on a clean, grease free glass slide.

• The smear is examined under oil immersion objective.

• Mature sperm cells are undifferentiated cells which are the testicular product as well as indicators of testicular spermatogenic function. A spermiogram reflects the testicular activity and fertility status of a male animal. • Disease conditions, age, stress factors, vaccination or any altered physiological conditions may affect the seminal quality. Objectives of Semen Evaluation • To provide essential information about the fertility status of the male animal, though the fertilizing capacity of the animal cannot be completely defined by these tests. • To diagnose various pathological conditions of testes and male genitalia. • To determine the eligibility for further processing of semen cryopreservation • To determine the potential of semen for AI purposes

ABSTRACT

The present study reports shoreline changes at Gopalpur along east coast of India for 30 years during 1973-2003. In order to understand the trend of sediment transport, shoreline changes at the vicinity areas viz. Rushikulya and Bahuda estuaries are also discussed. Geomorphological investigation is also carried out to understand the processes acting on this system. One Landsat image (1973) and two IRS 1C/1D images (1993 and 2003) were used for the study. The data were subjected to digital analysis using ERDAS Imagine and management of information layers using ARC/INFO GIS software. The results of the study show that the changes occurred differently in three distinct spatial features namely, i) sand spit ii) beach and, (iii) channel zone. Changes documented in these imageries reveal that the lengths of NE spit and SW spit are increased and decreased respectively in thirty years. Areas of NE and SW spits are also showing the similar pattern. Beach is almost stabilised and a slight decrease of 0.28 km in length is observed. However, area has been increased in the southern beach. Towards north, the beach area is also increased over a period of thirty years. The change of width of the beach is not found to be significant. The mouth near channel zone is reduced to 70 meter from 135 meter during the period of study.

Quality of silage is determined by nutrients content and intake potential of the silage. High quality silage is a stable feed, made from high quality pasture, which is preserved in the absence of oxygen by a high quality fermentation, to minimize any loss of feeding value. It is not possible to produce high quality silage from low quality pasture, no matter how good the fermentation is. The silage quality is generally used to indicate the success of fermentation and not to evaluate the feeding value of the silage. However, the fermentation quality and nutritional value of the silage are usually highly correlated because a poor fermentation can result in great loss of the digestible nutrients (Sutoh et al., 1970; Uchida and Sutoh, 1973). Therefore, both the quality of the ensiled pasture and the quality of the fermentation must be considered.

Abstract

The data for the present investigation were obtained from the performance records of 1081 crossbred cattle progeny of 65 sires maintained at Instructional Dairy Farm Nagla of G.B. Pant University of Agriculture & Technology Pantnagar, distributed over a period of 40 years from 1966-2005. A total of 65 sires were evaluated on the basis of single and multi traits of their progeny. For single trait sire evaluation, FLMY was considered as principal trait under univariate models viz- simple daughter’s average () method, least squares method (LSM), DFREML-I method and BLUP-I method. However, for evaluation of sires by multi traits FLMY+AFC, FLMY+FLP and FLMY+AFC+FLP, the multivariate models viz. DFREML-II, DFREML-III, DFREML-IV, BLUP-II, BLUP-III and BLUP-IV method were used. The lowest average breeding value (2616.25) for the trait was obtained by () method and the highest average breeding value (2660.42 kg) was obtained by the rest nine methods. The accuracy, efficiency and stability of different sire indices were compared to judge their effectiveness. The evaluation method that gave the lowest error variance was considered to be most efficient.

Abstract

Twenty seven genotypes including two wild relatives of strawberry were evaluated for resistance against leaf spot caused by various fungal species viz.,Phyllosticta, Pestalotia, Hainesia lythri and Phyllosticta fragaricola under natural conditions. None of the genotypes was found to be resistant against leaf spot. However, the cultivar ‘Fern’ showed moderately susceptible reaction whereas the remaining genotypes were either susceptible or highly susceptible, suggesting the need for diversifying the germplasm either through open pollinated seedling selection or through hybridizing genotypes of divergent origin for resistance against leaf spot.

Introduction

In the past few decades, there has been a considerable demand for certain air-breathing fishes from India, mainly in the research laboratories of western countries. This is probably due to their unique modifications, especially in the respiratory and circulatory systems. Though, the air-breathing fishes are capable of extracting oxygen both from water as well as air, yet their transportation to long distances in living conditions posed several problems, such as hypoxia, injury, disease and finally death.

Proper sanitization of all the equipment and accessories is one of the essential steps for the study of the structure of gills, determination of oxygen uptake of fishes under normal conditions, under the association, under anaesthetization, under ammonia toxicity and all other steps of packing and transportation in this pandemic of COVID-19.

For effective live fish transportation, inside and out comprehension on the ideal ecological conditions for negligible pressure and greatest endurance is required. At the point when the fish leaves its normal climate, it should be in a self-supportable climate that provisions important necessities, for example, ideal temperature, oxygen and so forth.

Transportation of different life cycle stages (spawn, hatchlings, fry, fingerlings and adults) of fish is traditionally done in different types of containers. The age-old practice of transportation entails heavy mortality probably due to depletion of oxygen, hypertension of carbon dioxide, the toxicity of accumulating wastes, hyperactive strain and exhaustion, infection, injury and variation in pH, temperature, salinity and hardness etc (Jhingran, 1985). A portion of dissolved oxygen is utilized both by the fish and other microorganisms for their metabolism. As a result, the system becomes gradually deplete of oxygen and affects the fish. To overcome the problem of high mortality during transportation, it is essential to evaluate suitable conditions for their transportation. An inexpensive or less expensive method of live fish transport will help our aqua-culturists in many ways.

Probably since the beginning of human life on the planet, they have used local fruits and vegetables. For a long time, they have enjoyed the fruit of the wild trees without knowing how to successfully produce them. Such native fruit trees have many advantages. These trees have an extraordinary genetic diversity that can be exploited in breeding programs and genetic advancement of domestic varieties (Khadivi et al., 2020). Many indigenous fruits are still highly valuable, and the harvesting and selling of these forest fruits contribute significantly to the local economy of families in the area. The product collected from forest trees is completely healthy and in terms of quality, they may even be equal to “organic fruits”. In a most recently published book chapter entitled organic pomegranate production in Iran, compiled by Alizadeh and Varasteh (2024), wild pomegranates were considered as noble source of healthy food. Given the multifunctional, ubiquitous nature of wild edible fruits the present chapter was compiled to introduce wild fruit trees of northern Iran with a focus on providing more detailed information about wild pomegranates.
Geographical Aspects of Northern Iran Northern Iran
is a geographical region encompassing a relatively large and fertile area, located along the southern border of the Caspian Sea and the Alborz Mountains. Upon closer examination of the map of Iran (Fig. 1), one can identify three northern provinces: Golestan, Mazandaran, and Gilan. These provinces all share borders with the Caspian Sea and the Alborz Mountains. The Alborz mountain range extends from the western border with the Republic of Azerbaijan to the eastern border with Turkmenistan (Fig.1).

Programme evaluation requires a systematic sequence of activities through which programme objectives, implementation processes, outcomes and impacts can be examined using credible evidence. This chapter presents the practical process of conducting an evaluation from programme identification through the use of evaluation findings. It explains how evaluators identify the programme and its objectives, determine the appropriate stage and type of evaluation, and assess the technical, financial, operational and time feasibility of the evaluation. Particular attention is given to identifying and consulting key stakeholders because their perspectives, expectations and information are important for a relevant and participatory evaluation process. The chapter further addresses approaches to data collection, sampling, quantitative and qualitative analysis, interpretation and communication of findings. It emphasizes that evaluation findings should not merely be reported but should contribute to programme improvement, decision-making and learning. The chapter also considers the evaluation of evaluation itself, or meta-evaluation, as an important mechanism for assessing the quality, credibility and usefulness of evaluation processes and reports

Evaluation Theory vs Practice

Theory based evaluation is an approach to evaluation (i.e., a conceptual analytical model) and not a specific method or technique. It is a way of structuring and undertaking analysis in an evaluation. A theory of change explains how an intervention is expected to produce its results

What are Evaluation Theories?

Evaluation theories refer to the conceptual frameworks, models, and principles that guide the systematic assessment and analysis of programs, policies, interventions, and other social phenomena. They provide a set of organizing principles and methodologies for evaluating the effectiveness, efficiency, relevance, and sustainability of various interventions and initiatives in different domains, including education, healthcare, social services, environmental protection, and public policy. Evaluation theories draw from various disciplines, such as psychology, sociology, economics, statistics, and management, and they may emphasize different aspects of the evaluation process, such as the role of stakeholders, the criteria for success, the methods for data collection and analysis, and the use of evaluation results.
i. Programme theory
Program theory defines as the mechanisms that mediate between the delivery (and receipt) of the program and the emergence of the outcomes of interest. Programme theory, variously referred to as programme theory, programme logic, theory-based evaluation or theory of change, theory-driven evaluation, theory-of-action, intervention logic, impact pathway analysis, and programme theory-driven evaluation science refers to a variety of ways of developing a causal modal linking programme inputs and activities to a chain of intended or observed outcomes, and then using this model to guide the
evaluation. The term ‘logic model’ is used to refer to the summarized theory of how the intervention works (usually in diagrammatic form) and ‘programme theory evaluation’ is used for the process of developing a logic model and using this in some way in an evaluation. Most approaches to building logic models have focused on simple, linear models, but some have explored how non-linear models might be used to better represent programmes and guide their evaluation. In particular, a number of evaluators have incorporated concepts of complexity in their discussion and use of logic models. 

Project evaluation is a systematic and objective assessment of an ongoing or completed project. The aim is to determine the relevance and level of achievement of project objectives, development effectiveness, efficiency, impact and sustainability. It is a time bound exercise that attempt to access, systematically and objectively, the relevant / performance and success of a programme / project.

5.1 Introduction

Evanescent field absorption spectroscopy is a powerful well-established laboratory technique for chemical analysis. The technique utilizes the evanescent wave penetration at the boundary between two dielectric media in conditions of attenuated total reflection (ATR). One of the media, a thin slab-shaped non-absorbing crystal, is called a waveguide, while the other medium of lower refractive index is the absorbing sample being studied. At each reflection at the boundary of the crystal and the sample, the penetration of the evanescent wave of the guided ray into the absorbing sample gives rise to a reduction of the power propagating in the crystal. The degree of absorption depends on the amplitude of the evanescent field in the sample medium and the number of reflections within the waveguide. The former increases dramatically for incident angles approaching the crystal-sample critical angle while the latter increases with the decrease in the thickness of the waveguide. The number of reflections can also be increased by increasing the length of the waveguide. Thus, to achieve maximum absorption, an unclad optical fiber is well suited for evanescent wave absorption spectroscopy. This is because, unlike the crystal waveguide, the narrow core diameter of the fiber provides a large number of reflections per unit length. Further, the use of an optical fiber to transmit light to a section of its core in contact with an absorbing sample offers the possibility of remote sensing or in-line analysis. These advantages, together with the benefits of simplicity, reliability, flexibility and relatively low cost have motivated a number of research groups all over the world to investigate evanescent wave spectroscopy at the surface of an unclad optical fiber. This chapter will be devoted to the fiber optic sensors utilizing evanescent field absorption spectroscopy.

The change of state of water from solid and liquid to the vapour and its diffusion into the atmosphere is referred as Evaporation. In the meteorology, evaporation is defined as the maximum possible loss of moisture from a wet, horizontal, flat surface exposed to weather which exist in the vicinity of plants.

FACTORS AFFECTING EVAPORATION

1. Those affecting water supply at the evaporating surface. i.e., soil and plants including soil storage capacity, rainfall and irrigation and

2. Those affecting energy supply to the evaporating surface like solar radiation.

This chapter is fundamental to agricultural water management, as it explains how water moves from the land surface and plants back into the atmosphere, directly influencing irrigation needs and drought impacts. Water is the lifeblood of agriculture, and its efficient management is paramount for sustainable food production. Understanding how water is lost from the soil and plants to the atmosphere is central to optimizing irrigation and assessing crop water needs. This chapter delves into the concepts of evaporation, transpiration, their combined effect as evapotranspiration, and how these relate to overall crop water use (Fig.5.1).

Definition: Evaporation is the physical process by which liquid water is converted into water vapor and transferred from the land surface (e.g., bare soil, water bodies, or wet plant surfaces) into the atmosphere. It is purely a physical process driven by solar energy and the vapor pressure gradient between the surface and the air.

7.1 Introduction

Evaporation is an unit operation which converts a liquid into a vapour, leaving behind a concentrated solution or a higher boiling liquid. In other words, the goal of evaporation is to vaporize most of the water from a solution containing a desired product. Heat is the main tool in evaporation, and the process occurs more readily at high temperature and low pressures. Removal of water from foods provides microbiological stability, reduces deteriorative chemical reactions, and reduces transportation and storage costs. Evaporation can be distinguished from some other drying methods in that the final product of evaporation is a concentrated liquid, not a solid. It also differs from distillation, since the vapours produced in the evaporator are not further divided into fractions.

1. Introduction

Foods available in nature and, in some cases, the products made from it thereof contain quite an amount of water. This water not only adds volume to the food products but also provides a sight for attack by the micro organisms. Also, removal of water becomes essential if this water interferes with the end product chracteristics. There are several processes in food industries which are designed to get rid of this excess water, such processes are called concentration processes. The processes which can remove water from food substances are,- evaporation, freeze concentration and membrane based processes. All these process have their limitations in rendering solid content to the final product (Fig. 1). Perhaps, these limitations can be overcome by combinig the processes.

The objectives that are fulfilled by the concentration processes can be enumerated as follows:

10.1 Evapotranspiration (ET = Evaporation + Transpiration)

Evaporation is a diffusive process by which water from natural surfaces, such as free water surface, bare soil, from live or dead vegetation foliage (intercepted water, dewfall, guttation etc) is lost in the form of vapour to the atmosphere. It is one of the basic components of hydrologic cycle.

Likewise transpiration is a process by which water is lost in the form of vapour through plant surfaces, particularly leaves. In this process water is essentially absorbed by the plant roots due to water potential gradients and it moves upward through the stem and is ultimately lost into the atmosphere through numerous minute stomata in the plant leaves. It is basically an evaporation process. However, unlike evaporation from a water or soil surface, plant structure and stomatal behaviour operating in conjunction with the physical principles governing evaporation modify transpiration.

Thus, evapotranspiration is a combined loss of water from the soil (evaporation) and plant (transpiration) surfaces to the atmosphere through vaporization of liquid water, and is expressed in depth per unit time (for example mm/ day). Quantification of evapotranspiration is required in the context of many issues:

Evapotranspiration is the combination of two separate processes named evaporation and transpiration. Evaporation accounts for the movement of water to the air from sources such as the waterbodies and soil. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapour through stomata in its leaves. So evapotranspiration is a bio-physical process.

Evaporation

The change of state of water from liquid to the vapour and its diffusion into the atmosphere is referred to as evaporation. During evaporation, water molecules absorb energy which gives them the motion required to escape from the surface of liquid and become a gas. Since a certain amount of energy is consumed in the process of evaporation, the remaining liquid is cooled by an equivalent amount. Thus, the process of evaporation is always accompanied by a cooling effect.

As evaporation proceeds, the surrounding air becomes gradually saturated with water vapour and the process will slow down and might stop if the wet air is not transferred to the atmosphere. The replacement of the saturated air with drier air depends greatly on wind speed. Hence, solar radiation, air temperature, air humidity and wind speed are meteorological parameters to be considered when assessing the evaporation process.

In agrometeorology, evaporation is defined as the maximum possible loss of moisture from a wet, horizontal, flat surface exposed to weather parameters, which exist in the vicinity of plants. Evaporation is an essential part of the water cycle. It is the primary pathway through which water moves from the liquid state back into the water cycle as atmospheric water vapour. The oceans, seas, lakes and rivers provide nearly 90 per cent of the moisture in the atmosphere via evaporation, with the remaining 10 per cent being contributed by plant transpiration. A very small amount of water vapour enters the atmosphere through sublimation, the process by which water changes from a solid (ice or snow) state to a gaseous one, bypassing the liquid phase.

19.1 Introduction

The combination of two separate processes whereby water is lost on the one hand from the soil surface by evaporation and on the other hand from the tree by transpiration is referred to as evapotranspiration (ET).

19.2 Evaporation

Evaporation is the process whereby liquid water is converted into water vapour (vaporization) and removed from the evaporating surface (vapour removal). Water evaporates from a variety of surfaces, such as lakes, rivers, pavements, soils and wet vegetation. (Penman, 1963).

Energy is required to change the state of the molecules of water from liquid to vapour. Direct solar radiation and, to a lesser extent, the ambient temperature of the air provide this energy. The driving force to remove water vapour from the evaporating surface is the difference between the water vapour pressure at the evaporating surface and that of the surrounding atmosphere. As evaporation proceeds, the surrounding air becomes gradually saturated and the process will slow down and might stop if the wet air is not transferred to the atmosphere. The replacement of the saturated air with drier air depends greatly on wind speed. Hence, solar radiation, air temperature, air humidity and wind speed are climatological parameters to consider when assessing the evaporation process.

Where the evaporating surface is the soil surface, the degree of shading of the tree canopy and the amount of water available at the evaporating surface are other factors that affect the evaporation process. Frequent rains, irrigation and water transported upwards in a soil from a shallow water table wet the soil surface. Where the soil is able to supply water fast enough to satisfy the evaporation demand, the evaporation from the soil is determined only by the meteorological conditions. However, where the interval between rains and irrigation becomes large and the ability of the soil to conduct moisture to pear the surface is small, the water content in the topsoil drops and the soil surface dries out. Under these circumstances the limited availability of water exerts a controlling influence on soil evaporation. In the absence of any supply of water to the soil surface, evaporation decreases rapidly and may cease almost completely within a few days.

The movement of water from soil to the crop canopy and leaves to provide water for transpiration and the effect of weather factors on transpiration is most important area of study. When the crop is just sown, there will be an only evaporation of water from the soil. After germination of seeds there will be emergence of seedlings. After the emergence of seedlings there will be formation of leaves. The small leaves start intercepting the incoming solar radiation and absorb some portion of solar energy, get heated and there will be evaporation turn off water from the stomata of the leaf. When water vapour escapes into the atmosphere through the stomata of leaf, the plant absorbs carbon dioxide which results in photosynthetic activity. During night time, there will not be any photosynthesis due to absence of sunlight. The plants use parts of the photosynthetic accumulate for its metabolic activity and the process is called maintenance respiration. The balance of the photosynthetic accumulate contributes to the expansion of leaves and increased dry matter accumulation in crop plans. The process of dry matter accumulation in plants is called crop growth. When the seedlings start growing, there will be formation of tillers or branches. When the leaves grow it reaches a stage when the crop will be completely shading the ground and the soil evaporation will be minimum and maximum amount of water is lost only through evapotranspiration (Fig.6.1).

In cropped soils, evaporation refers to evaporation of water from the soil and transpiration refers to evaporation of water from plant canopies (Fig.6.1). Evaporation and transpiration play very significant role in mass and energy transfer. The latent heat of vaporization is defined as amount of heat required to evaporate 1 gm of water at a temperature of 100°C; i.e. the boiling point of water is 540 cal/gm. The amount of heat required for evaporation of water at ordinary temperature of about say 30°C is 610 cal/gm.
Fig. 6.1: Process of evapotranspiration
The evapotranspiration from crop depends upon several factors as indicated below:
• The evapotranspiration increases with increase in air temperature.
• The evapotranspiration increases with increase in wind speed up to a certain limit.
• The evapotranspiration decreases with increase in relative humidity
• The evapotranspiration increases with increase in Saturation Vapor Pressure Deficit (SVPD). SVPD = es – ea

Humans possess an innate tendency to preserve their experiences and knowledge. Throughout evolution, this inclination led to the recording of text and images on materials such as stone, rock, leaves, bark, and eventually paper. The desire to preserve not only written and visual content but also sound culminated in the invention of sound recording in the late 19th century. This innovation enabled humanity to capture and reproduce auditory experiences.

In 1924, Western Electric in the United States developed the first electromagnetic sound recording machine. This device marked a significant advancement, as it allowed for the conversion of acoustic waves into electrical signals that could drive a stylus to inscribe the sounds onto a medium, such as wax records. Over time, the technology evolved, leading to the widespread adoption of electromagnetic recording on plastic tapes coated with materials like ferrous oxide and ferric oxide. The late 20th century saw the introduction of Compact Discs (CDs), followed by DVDs and Blu-ray discs. Today, sound recordings are commonly stored on hard drives, flash drives, and memory cards.

The geologists of the Indian subcontinent have all along been of the opinion, that, the southern part of the Indian Peninsula is a stable shield area. But, the recently acquired IRS-1A image of June, 1988 vividly displays spectacular geomorphic anomalies suggesting that this part of the Indian subcontinent is prone to earth movements. In order to unearth more evidences on such earth movements / neotectonism in Tamil Nadu, the IRS-1A image of Coromandel coast of Tamil Nadu was analysed ( Fig. 1).

OBSERVATIONS

• The IRS-1A image conspicuously displays three contrasting morphotectonic domains in the study area marked by the western undissected Tertiary upland (Vallam upland), central highly dissected Tertiary upland (Pattukottai -Mannargudi upland) and the eastern Cauvery delta (Fig 1 and 2). These three domains are separated by two conspicuous N-S trending lineaments (E and F, Fig.1 and 2) namely the Tanjavur - Avadaiyarkovil lineament in the west and Kumbakonam -Muttupet lineament in the east.
• In addition, two more E-W trending lineaments (G and H, Fig.1 and 2) are also observed trifurcating the undissected Vallam upland into three blocks.
• Along these lineaments, especially the Tanjavur -Avadaiyarkovil and Kumbakonam -Muttupet lineaments, the rivers show conspicuous drainage anomalies in the form of drainage deflection, drainage compression etc., wherever they transect the lineaments.

The Middle Ages and the Printing Revolution
During the Middle Ages, advertising remained largely oral, with traders and peddlers using verbal promotion. However, the invention of the printing press by Johannes Gutenberg in the 15th century revolutionized advertising. The first printed advertisements appeared in the late 15th century, including handbills and posters that promoted books and medicines (Elliott, 1962). One of the earliest printed advertisements appeared in a 1477 English prayer book, promoting a sale by William Caxton, England’s first printer (Presbrey, 1929). The printing revolution facilitated mass communication,

Introduction Agricultural extension plays a pivotal role in the advancement of agriculture in any nation. It encompasses the dissemination of knowledge, guidance, and assistance to farmers, rural communities, and various stakeholders involved in the agricultural domain. The primary objective of agricultural extension is to empower farmers to enhance their productivity, income, and overall quality of life. The concept of agricultural extension has undergone significant transformations across various countries, including India. This article will delve into the historical progression of agricultural extension both internationally and within the Indian context.

Agricultural extension plays a critical role in bridging the gap between research and farmers by disseminating knowledge, improving skills and enabling farmers to adopt new practices that can boost productivity and sustainability. Over the years, the role of extension has evolved from a focus on productivity to a more holistic approach, which now includes market orientation, environmental sustainability and rural development. Evaluating the role of extension involves examining its contributions to rural livelihoods, food security and the broader agricultural ecosystem.
Impact on Productivity and Food Security: Extension services have traditionally aimed to increase agricultural productivity through technology dissemination and best practices, contributing significantly to food security in countries like India.
Market and Value Chain Linkages: Modern extension efforts emphasize connecting farmers to markets, enhancing income potential, and promoting value addition, especially through initiatives like FPOs and ICT-based tools.
Environmental Sustainability: With a rising focus on climate resilience, extension has expanded to educate farmers on sustainable practices, water conservation, soil health, and organic farming.
Empowerment and Community Development: Extension now goes beyond agriculture, aiming to empower rural communities by encouraging selfreliance, entrepreneurship, and participatory decision-making.
The evolution of agricultural extension in India reflects a dynamic journey shaped by various agricultural challenges, government policies, and the changing needs of rural communities. The main stages in the development of agricultural extension in India are as follows:
A. Pre-Independence Period (Before 1947)
Here’s a brief overview of each pre-independence rural development program along with their objectives and significance:

Agriculture has progressed from labour-intensive traditional practices through mechanization and the Green Revolution to precision agriculture and Agriculture 5.0. This chapter traces that historical development and identifies limitations associated with conventional farming, including inefficient resource use, environmental degradation and weak adaptability. It explains how GPS-guided machinery, sensors and precision technologies prepared the foundation for intelligent systems. Artificial neural networks, deep learning and fuzzy logic now process data from IoT devices, UAVs and satellites to support automated irrigation, crop monitoring and soil analysis. The chapter emphasizes that integrating human knowledge with computational power is increasingly essential for global food security, sustainability and climate resilience.

Introduction

Baking is not a new concept to us. Baking process dates thousand years back since the Paleolithic age. During those days, the baking was done by simply grinding the grains, mixed with water and baked on the hot rocks. The bread produced that time was not leavened but flat. Ancient Egyptians have the credit for development of baking between 2600-1200 BC. Roman Empire also had the popularity of the art of baking and bakeries were in existence in Europe too during Middle Age. Baking was considered a highly respected profession under the Roman Empire. The art of baking has travelled a long journey since then. The bakery and confectionary has undergone a gradual evolution with time. Great technical progress stared in the nineteenth century. Development of automatic machines reduced the task of the manual labour and because of this development the bakers could perform many more tasks with the machines. Today’s baking has a dependency on the machines. All the work is performed by the automated machines whereas the bakers only control the machine operations. The baking process has become easier, the efficiency has increased and the quality of the products has improved because of these high-tech machines. The preparation of bakery products using traditional methods has also improved over the time to minimize the energy and time consumption. Today’s consumer is very much concerned about his/her health and look for the healthy options in baked products. The trend has led to various innovative formulations for the baked products so that the health benefits may also be provided not only the calories. This chapter will discuss various advancements and trends in different types of bakery and confectionary products.

The Rochdale Society of Equitable Pioneers was founded in Rochdale, England, in 1844 and soon became a prototype for cooperatives worldwide. Its governance structure, known as the Rochdale Principles, is still a key guideline for the design of cooperatives. The social dislocations of the Industrial Revolution inspired workers and enlightened entrepreneurs to establish cooperative societies since the beginning of the nineteenth century.

Abstract

Camelids across the world are reared for milk, meat, draught, race and tourism. Camelids are also the source of world’s finest natural fibre. They are distributed in the South American, African, Arabian and Asian countries. Apart from this a feral population exists in Australia and recent reports indicate that a few animals of the species are also being reared in Europe. Camel (Camelus dromedarius) is the predominant species of the camelids. The world camel population shows an increasing trend with 12.92 m in 1961 to 26.63 m in 2011 producing 0.42 m tonnes of meat and 2.11 m tonnes of milk per annum. The top 20 camel rearing countries produce both milk and meat with the exception of India and Pakistan as per FAO data. There are about 83 populations of the dromedary camels in the world spread mainly across African and Asian countries. There are about 3.04 m Alpacas in world with Huacaya and Suri as the two main populations and 3.24 m Llamas with Chaku and Kara as the two main populations. The Guanaco population in the world is about 0.5 m and that of Vicuna is 0.35 m. The wild Bactrian camels are around a thousand but the domesticated Bactrian camels are about 0.6 m. The Alpaca and Bactrian camel genome has been sequenced whereas the expressed sequence tags of the Dromedary are available in the public domain. A brief account of evolution, present status and conservation of camelids is discussed.

Modern farm planning involves nonlinear, discontinuous and multi-objective problems that conventional optimization methods may not solve effectively. This chapter examines Genetic Algorithms, Particle Swarm Optimization and Differential Evolution for improving agricultural resource allocation. These nature-inspired techniques can simultaneously address crop yield, water use, fertilizer application, environmental effects and financial viability. Their integration with deep-learning forecasts and crop-simulation systems enables more realistic optimization. Multi-objective evolutionary algorithms identify Pareto-optimal alternatives, allowing decision-makers to balance productivity and ecological sustainability. The chapter also emphasizes explainable artificial intelligence, economical implementation and farmer usability as necessary conditions for transferring evolutionary optimization methods from experimental research to practical farm management.

Origin of Species

A biological species is a group of reproductively isolated individuals

Speciation usually occurs via a branching process called cladogenesis

Divergent evolution can be allopatric, parapatric, or sympatric

Müntzing was able to re-create an allotetraploid species

Evolution can proceed gradually or be punctuated by periods of rapid change

Introduction

Agriculture is vital to the Indian economy in terms of job creation, with nearly half of the Indian population relying on agriculture and related activities for a living. A large proportion of the population, particularly in rural areas, is illiterate. The rural population, which is illiterate and ignorant, is unable to cope with the complexities of agricultural technology management. As a result, vocational training and technology dissemination are few viable options for increasing production efficiency and achieving rapid and sustainable agricultural development. The State of Odisha derives more than a quarter of its revenue from agriculture. More than 40% of the people in the state of Odisha depend on farming as their primary source of income and way of life, making up more than 53% of the state’s workforce. whereas agricultural technology has developed into a logical extension of the traditions, conventions, knowledge, and skills that date back to the early days of human civilization and have continued to evolve over time. It was not just agriculture that produced food or other biological means; rather, it essentially presented a wide range of traditional values to make it abundantly evident that “TECHNOLOGY and TECHNIQUE” are the cultural means to satisfy the biological as well as social demand for life. To provide the necessary acceleration to the agricultural development, Agricultural Technology Management Agency (ATMA) Scheme was launched during 2005-06 in order to enrich farmer’s skills, knowledge and competency several developmental programmes/projects, in agriculture and allied sectors. In the state Odisha, a district level autonomous institute has taken the main responsibility of all technology dissemination activities at district level for development of farmers and farm women through its bottom –up approach. During 2010 the reforms made in ATMA project and farm persons were given due importance to its multifarious activities like training, demonstration, information support, input supply, market-oriented facilities, linking credit and exposure visit etc. These multi-purpose activities provide ample opportunities for the farm communities and makes the resources accessible for them. Additionally, ATMA served as a link between individuals in need and those with the means necessary for undergoing rapid technological change. It is also critical to evaluate various stakeholders of ATMA in order to enhance both its organisational and functional approach. This includes various parameters such as efficiency of skilled professionals of ATMA, availability of resources and feedback from farmer beneficiaries among other factors.

In case of Allahabad, it is evident that a major thrust catapulting the city to an invincible position was experienced immediately after 1857. These changes in the character of Allahabad along its journey which witnessed the resurgence of the pilgrim town into a front ranking educational and cultural node also saw the shades of capital center and finally its transition into a low profile city which today has lost its vitality and seem to be comparable to a non functioning muffossil town of Uttar Pradesh. The facts and figures representing the key events and a survey of the city enable us to establish a direct relationship between the functions and performance of the city.

The first part of the chapter is based on the inferences from the study on Allahabad covered earlier. The second part deals with testing these facts on ground by conducting interviews with eminent individuals who had been deeply associated with education and cultural status of Allahabad. The third part consists of the final inferences. Some critical conclusions are also borne out reflecting a clearer understanding of the phenomenon of decline of Allahabad.

11.1 Introduction

In the preceding chapter 10, we have discussed in detail, the test procedures for which it has been assumed that the sample size n is large, (i.e n >,30). Those tests are also known as approximate tests or z tests. But in case when sample size n is small i.e. n<30, the approximate test fails to deal with such problem and we apply the theory of exact sample, for small sample tests. The exact sample tests however can be applied to large samples also though the converse is not plausible. In all the exact sample tests, the basic assumption is that the parent population is normally distributed.

In this part we will discusse in details the exact sample tests (based on exact sampling distributions namely snedekor’s F, student’s t and chi square (c²) distributions. These distributions will be simply introduced in short because main emphasis has to be given only on the test procedures based on them.
