Introduction

The concept of Computer Aided Design (CAD) for landscape gardening is comparatively new. It can be defined as design and drafting of a landscape garden with the aid of computer. It can also be defined as use of information technology in garden designing. The core of the CAD system is software, which makes use of graphics for product representation. Computer aided designing is an important industrial art, extensively used in industry and landscape architecture designing and for many more purposes. For landscape designs, it represents a practical solution for the imperative needs of helping to visualise the future. Now-a-days, CAD is used to create 2D or 3D computer models. CAD assists the designer

Computer-based instructional teaching and learning platforms, commonly known as Learning Management Systems (LMS) or educational technology (EdTech) platforms, are designed to enhance the educational experience by integrating technology into the learning process. These platforms offer a range of tools and features that support both instructors and students in various educational activities. Here are some key platforms and their features:

Introduction

Agriculture has played an important role in the global economy in recent years. The further growth of the population is leading to a gradual decrease in the area of the agricultural land and further growing stresses on the farm system. Agricultural food production methods are rising in demand for successful and healthy. Innovative sensoring and motive technologies and advanced information and communications systems and Artificial Intelligence must supplement conventional agricultural management methods to speed up farm productivity growth more accurately, thereby promoting the production of high-quality and high-performance agriculture. Computer vision monitoring systems have become valuable tools in farm operations over the past decades, and their use has increased significantly.

What is Computer Vision?

Computer vision can be characterized as a field of AI for extracting information from digital images. The type of data obtained from an image may be different from recognition, navigational space measurements or applications of increased reality.

The applications of computer vision can also be described. Computer vision builds algorithms that recognize and use the quality of pictures for other purposes.

Milk may be concentrated as a necessary initial step in drying operation or as concentrating step in the manufacture of sweetened condensed milk or evaporated milk or the preparation of infant formulae. In order to preserve the milk constituents in a concentrated form, condensed milk/concentrated milk is manufactured from whole skim milk by removing or evaporating part of the water under vacuum. But this form of milk still has limited shelf life. Attempts to prolong the shelf life of this product have been made through the addition of bacterial growth inhibitor like sugar (sweetened condensed milk) or by heat processing (evaporated milk) to destroy the microorganisms.

Concentrated milk industry is an important segment of dairy industry. It plays an important role in the economy of industry. It serves as a balanced economy. It utilizes surplus milk in the flush season. It utilizes abundant milk production in certain localized area. It makes use of surplus milk below excellent grade. By either concentrating or drying less space is needed to store and it becomes less bulky and therefore it can be transported to any part of the world. The keeping quality of milk is increased. The concentrated products give considerable saving in the cost of packaging, storage and transportation. Milk concentrates can be easily reconstituted with required amount of water corresponding to that removed by evaporation to yield a product having normal consistency of milk. It is estimated that nearly two per cent of the world’s milk production is converted into different types of condensed or concentrated milks.

Brief history and developments: The present day concept of preservation of milk by concentration and by application of heat had the beginning with the pioneering work of French man Nicholas Appert around 1793. Gail Bordon of USA was first to commercially exploit the method of concentration of milk under vacuum. He was awarded U.S. Patent in the year 1856 for processing milk in a semi-fluid state after evaporating under vacuum. Commercial production of sweetened condensed milk by Gail Bordon started in 1856.

Definition and Significance of Plant Diseases
Definition
A plant disease is a harmful deviation from normal functioning caused by a persistent or semi-persistent agent leading to physiological disruptions, structural abnormalities, or economic loss in plants. It manifests through the interaction between the host (plant), pathogen (disease-causing agent), and environment, which together form the disease triangle.
According to George N. Agrios (2005), a plant disease can be defined as:
“Any harmful deviation from the normal functioning of physiological processes of plants, induced by continuous irritation of a primary causal agent, leading to symptoms.”
Revised Significance of Plant Diseases
1. Economic Importance: Plant diseases lead to large-scale losses in crop production, estimated to account for approximately 10–15% of global crop yields annually (Agrios, 2005). This translates to billions of dollars in losses each year.
2. Impact on Food Security: The destruction of staple food crops like rice, wheat, and maize by diseases threatens food security, particularly in developing countries.
3. Environmental Effects: Plant diseases contribute to ecosystem imbalances by disrupting natural plant populations and affecting biodiversity.

Quality has emerged as a decisive source of competitive advantage in the global apparel industry. Liberalization and increasing international competition have encouraged apparel manufacturers to adopt quality-management practices throughout their operations. Sustained quality must be maintained from the procurement of fabrics and other raw materials through manufacturing, finishing and delivery. Although finance, labour and resources are important, they cannot ensure long-term growth when customers are dissatisfied. Modern consumers have numerous choices and expect dependable products at reasonable prices. Consequently, manufacturers must provide consistent quality, value for money and customer satisfaction to build product confidence, brand loyalty and sustainable business growth.

Valorization refers to the process of enhancing the value or price of something, often through government intervention or by recognizing its inherent worth. It can involve stabilizing prices, creating value from overlooked materials, or promoting the importance of a particular concept. In the context of waste management, valorization specifically denotes the conversion of waste materials into useful, marketable products using innovative and sustainable methods. It plays a critical role in waste-to-value processes by shifting the focus from traditional waste disposal to resource recovery, aligning with the principles of a circular economy. Rather than viewing waste solely as an environmental challenge, valorization recognizes it as a valuable resource. When processed properly, waste can yield energy, materials, or bio-based products. Common techniques include composting, anaerobic digestion, pyrolysis, and recycling, which are used to extract value from agricultural, industrial, and municipal waste. The primary goals of valorization are to reduce environmental pollution, generate economic returns, promote sustainability, and lessen reliance on virgin raw materials. By driving innovation in biotechnology, materials science, and engineering, valorization supports the growth of eco-friendly industries and fosters long-term environmental responsibility. Ultimately, it transforms waste management into a proactive, profitable, and sustainable practice.
Meaning and Definition
Valorization refers to the process of enhancing or increasing the value of a material, product, or resource—particularly one that is considered waste or of low economic worth—by converting it into a more useful, marketable, or environmentally beneficial form.
Definition
Valorization is the act or process of transforming waste materials, by-products, or low-value resources into valuable products, energy, or materials through physical, chemical, or biological methods. Its goals are to reduce environmental impact while simultaneously generating economic and social benefits. As such, valorization is a fundamental principle of the circular economy and sustainable development.

Watershed management

Watershed is defined as a geohydrological unit draining to a common point by a system of drains. All lands on earth are part of one watershed or other. Watershed is thus the land and water area, which contributes runoff to a common point.

A watershed is an area of land and water bounded by a drainage divide within which the surface runoff collects and flows out of the watershed through a single outlet into a lager river or lake.

Cross-pollinated species, or outbreeders, are highly heterozygous, heterogeneous and carry a higher mutation load than the inbreeders. Their mode of reproduction bestows upon them considerable heterozygous balance under panmitic population structure. Inbreeding such species disturbs the natural rhythm and leads to inbreeding depression. It is, therefore, essential that if selfing has created any disturbance in outbreeders, the heterozygous structure be restored. Since artificial selfing and outcrossing can be carried out in such crops at will, all breeding methodologies, even those meant for self-pollinated crops, can be used for their improvement. In fact, allogamous crops have provided opportunities for innovating breeding procedures to achieve the maximum efficiency by combining selfing and outcrossing cycles.

Thus, the classical separation of breeding procedures for self- and cross-pollinated crops has become unnecessary, particularly, for outbreeders which are amenable to selfing. Exploitation of heterosis has been the major objective in cross-pollinated crops and most breeding procedures developed earlier aimed at maximising heterosis. In later years, with better understanding of genetic structure of populations and availability of efficient biometrical methods of estimating genetic parameters, newer procedures of accumulating desirable genes have been developed. The presently available breeding procedures for cross-pollinated crops can be broadly classified under two heads: (1) Hybrid development, and (2) Population improvement. Both these methodologies, though independent, are not mutually exclusive. The steps for operating the two procedures, however, have contrasting requirements. For hybrid development, fixation of genes through cycles of selfing is necessary whereas such fixation is avoided while developing populations. As can be seen from the scheme given below, in both cases the homozygosity attained through initial selfing is converted to heterozygosity at the end of breeding programme. Irrespective of whether hybrids, synthetics or composites are being developed, great emphasis is placed on the attainment of homogeneity in the end products.

Man-directed evolution of distinct types and cultivars (cultivated populations) of self-fertilised crops had their beginning about 10,000 to 12,000 years ago. As a breeding system, self-fertilisation favoured constancy and fitness (Stebbins, 1950) of the genotypes to the immediate environment. This provided an alternative to the slash and burn migrant agriculture of the Neolithic farmers (7,000-6,000 B.C.) and to stabilisation of production.

Manu Smriti (700–500 B.C.) proclaimed Subeejam Sukshetre Jayate Sampadyate meaning that good seed in a good field yields abundant produce. The knowledge that good seed is essential for a good harvest, led to conscious efforts for selecting types which provided a dependable source of food. Besides their utility as food, choice of plants and their seeds as progenitors of the next generation depended on personal fancy, observation and experience. As farmers learnt their crop plants better, they sorted them out into similar types (species). While migrating from the centres of origin they carried seeds of mixed populations.

Self-pollinated cereal crops of barley, wheat, oats and important grain legumes such as lentil, peas and chickpea spread from the Near East Centre, first to far and remote areas of Asia, Europe and Africa; and subsequently in comparatively recent times, to the Americas and Australia. In new environments, the introduced mixed populations diversified into well adapted identities of land races. These land races continued to be the main basis of cereal production till early 1900. Improvement in crop plants made by some early civilisations was mainly through introduction and mass selection, based on the natural tendency of preserving the seeds of preferred colour and size from vigorous, healthy and more productive plants.

It was only after the rediscovery of Mendel’s laws in 1900 that breeding procedures based on the knowledge of the genetic principles and the inheritance pattern of different characteristics were developed. This permitted the improvement of crops with objectivity and predictability.

Concepts

The concepts of development communication has now been adopted by almost all the countries of the third world. It is all about to inform, motivate and influence all sectors and levels of peoples of a developing country to use unfamiliar ideas, skills and instruments, thus adding the long neglected social component without which the process of development remain dormant. Thus importance of communication as a tool to motivate and persuade people for eliciting positive response to various developmental ideas grow manifold.

The evolution of the term ‘ development’ has had a fascinating history about itself. In its broadest sense ‘ development’ tends to be umbrella under which several phenomena - varying from human and spiritual development to economic and community development, as well as technological development have become related. Defining ‘development’ is not an easy talk. It has been interpreted in various ways by sociologists, economists and development planners. They defend the term according to their own frame of reference. Modernization, social change and enhancing quality of life are often used in one way of the other in explaining the term. In all cases development suggest some amount of improvement, self-reliance, uplift and progress as also awareness and self-awareness to some extent.

The eminent communication scholar, Everett M. Rogers, has development this process of thinking about development in this book communication and development critical perspectives (1976), as under “Development as a widely participatory process of social change in a society, intended to bring about both social and material advancement (including greater equality freedom and other valued qualities) for the majority of the people through their gaining greater control over their environment.

The new paradigm of development does not envisage the role of communication as that of magic multiplier of development, however, it is certainly envisaged to play a facilitate role in the process of development.

Introduction
Understanding the concepts of technology transfer, licensing, and commercialization is crucial as it plays an important role in understanding how scientific discoveries leads to generation of new technologies further making them the impactful solutions that benefit industries and society. In the context of Indian HEIs, this especially important because a large volume of impactful research often remains underutilized due to limited commercialization channels. This chapter explains the terminology, essential components of technology transfer, outlines its significance for the innovation ecosystem. It also outlines the evolution of India’s technology transfer ecosystem, and emphasizes while understanding its potential to boost India’s economy, encourage entrepreneurship, and strengthen global competitiveness. From initial idea to a market-ready product is complex and multiphased process. The stepwise process is shown in Figure 1. It highlights a structured pathway consisting of five core phases: Idea/Concept, Technology development, Intellectual Property (IP) rights, Technology transfer, and Technology commercialisation.
Phase 1: Idea/Concept stage
This process of technology transfer starts with the Idea/Concept phase, where an invention is created. Each phase plays an important role in transforming raw scientific knowledge into innovative solutions that benefit society and generate economic value. In this phase breakthrough ideas emerge, within labs. Researchers explore and develop initial proof-of-concept or prototypes to validate their ideas. At this stage, the focus is primarily on knowledge creation rather than commercialization. This pathway of technology transition is summarized in Figure 1.

Conflict represents an inevitable and potentially constructive dimension of community mobilization that emerges when individuals and groups with different interests, values, perspectives, or needs interact in pursuit of shared or competing goals. Rather than viewing conflict as purely destructive or problematic, effective community mobilization requires sophisticated understanding of conflict dynamics and skilled application of management strategies that can transform disagreements into opportunities for learning, innovation, and strengthened relationships that enhance collective capacity and democratic participation. The complexity of contemporary community challenges requires bringing together diverse stakeholders with varying backgrounds, experiences, priorities, and approaches to problem-solving, creating natural conditions for disagreement and tension that must be navigated skillfully to maintain group cohesion while harnessing the creative potential that emerges from diverse perspectives and approaches. Understa

Conservation agriculture (CA) defined as minimal soil disturbance (no-till) and permanent soil cover (mulch) combined with rotations is a recent agricultural management system that is gaining popularity in many parts of the world. Cultivation is defined by the Oxford English dictionary as “the tilling of land”, “the raising of a crop by tillage” or “to loosen or break up soil”. Other terms used in this dictionary include “improvement or increase in (soil) fertility”. All these definitions indicate that cultivation is synonymous with tillage or ploughing.

The other important definition that has been debated and defined in many papers is the word “sustainable”. The Oxford dictionary defines this term as “capable of being borne or endured, upheld, defended, maintainable”. Something that is sustained is “kept up without intermission or flagging, maintained over a long period”. This is an important concept in today’s agriculture since the human race will not want to compromise the ability of its future offspring to produce their food needs by damaging the natural resources used to feed the population today.

Green Revolution has increased food grain production by four fold since 1950–51 with the adoption of HYVs, intense input use, extensive tillage, burning of residues and irrigation. The intense cultivation has lead to degradation of natural resource such as soil, water, vegetation etc. In this context, globally conservation agriculture (CA) has opened a new paradigm as it has potential for higher resource use efficiency, water productivity and climate change mitigation through its key principles. Total area and percentage of total area under no tillage practised as part of conservation agriculture in different continents is given in Table 92.

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.

Introduction
The richness of a country can be measured by its biological diversity. It is essential to both human existence and financial security. The most basic concept of biodiversity is expressed by the diversity of creatures. Biodiversity is represented by the supplies of food, clothing, shelter, and medicines provided by plants; by the sources of food, assistance, wild life, and human resource efficiency provided by animals; and by the patterns of variation seen in the microbiological world. More than 20,000 kinds of ants, 3,000,000 species of beetles, 28,000 species of fish, and almost 20,000 species of orchids would be hard for the average person to believe.
Definitions
• The collection and interplay of genes, species, and ecological diversity in a specific location and time is known as biodiversity. Different genes, species, habitats, and their relative abundance are all included in the phrase biodiversity.
• The portion of nature known as biodiversity comprises the genetic variations between individuals of the same species as well as the variety and richness of all plant and animal species at various spatial dimensions, such as a region, a nation, and the entire planet.
• “The diversity of life, which encompasses ecosystem or community diversity, species diversity, and genetic diversity, and includes the entire range of variety and variability within and among living organisms and the ecological complexes in which they occur,” is another definition for it.

The basic feature of the Pre-British India was a village, which was economically a water-tight compartment fulfilling the three basic functions of economy, i.e., production, distribution and consumption, within the village community without outside world dependence, except the salt and kerosene. Every village was a self-sufficient unit with dependence on agriculture carried out by community people of different castes having the occupational specialization with interdependence, viz. jajmani system and alike.

Developments in the means of communications and the opening of Suez Canal in 1869 introduced fundamental and far-reaching changes in the social system and economic life of Indians by transforming self-sufficient village economy to new modes and means based on competition, market and price mechanism. This change was deliberated by Britishers for meeting the requirement of raw material and the diversification to tea, jute and indigo took place. Cotton also got importance but agriculture did not find place for vegetables. Famines were very common and crop production depended on monsoon rains to the large extent. Britishers developed cotton, jute and mineral trade for their vested interests.

Britishers emphasized the development of railways for better mobility of their troops, commercial crop produce and minerals but the Report of Famine Commission 1901 bitterly criticized the Government for the step-motherly treatment given to irrigation facilities as compared to railways. The irrigation policy of the Government in 19th century was determined purely from concerns for adequate returns on investment and profit was of Rs. 81 lakhs after paying 4% interest on amount invested on irrigation development in 1896-97. Irrigation Commission was established and a sum of Rs. 42 crore was spent on irrigation by 1911. By 1930, about 30 million acres were brought under canal irrigation, which was far larger than the irrigated area in any other country of the world. Even in the USA, the area under canal irrigation was two-third that of India. Vegetables cultivation did not find place in Indian agriculture and also in diet of villagers. Their cultivation remained restricted to the periphery of the urban centres for meeting the demand of upper class elites only.

With renewed interest in rainfed agriculture during 1970s, both the national (AICRPDA and CRIDA) and international institutions (ICRISAT) have studied several aspects of rainwater management. Recommendations have been made after their through testing both at the research Stations and on farmer’s fields. Initially these technologies were accepted by the farmers because of the pursuation by the Scientists and the incentives, but many of them are forgotten once the support is withdrawn. It is now time for us to examine whether the technologies themselves were weak or certain components were missing malfunctioning of the software may be due to a bug right from the beginning or it entered into the system at a later stage. It is also possible that we neglected certain critical inputs which became major constraints making the system defunct. Whatever the reason it should be identified and set right if the technology has to continue as tool for tackling the challenges of rainfed agriculture.

Main constraints of dry land agriculture to enhance the productivity are classified as follows:

Root harvesting equipment is useful in harvesting root crops such as potatoes, carrots, beets, turnips, onions, sweet potatoes, and other underground crops. These machines are designed to dig, lift, and separate the roots from the soil while minimizing damage to the crops. Root harvesting equipment can vary in size and design depending on the crop being harvested and the scale of the operation. Here’s an overview of the different types of root harvesting equipment and their features:
VARIANTS OF ROOT HARVESTING EQUIPMENT
Potato Harvesters
• Two-Row Potato Harvesters: These machines are designed to harvest two rows of potatoes at a time. They dig up the potatoes from the soil, separate the soil, and lift the potatoes onto a conveyor system for sorting and further processing.
• Single-Row Potato Harvesters: These are typically smaller machines used for smaller fields or specialized crops. They work similarly to two-row harvesters but are designed for single-row efficiency.
• Self-Propelled Potato Harvesters: These are large, fully mechanized machines capable of harvesting large fields. They often come with additional features like sorting tables and storage bins.
• Trailed Potato Harvesters: These harvesters are attached to a tractor and are commonly used for medium to large-scale potato operations. They consist of digging units, separation mechanisms, and conveyors to lift and transport potatoes.
