4.1 Introduction
Companies that produce tangible items or offer services must drastically increase their productivity in order to maintain their operations in the face of intensifying global competition. A single quantum jump productivity enhancement technique or multiple concurrent incremental improvement productivity strategies can both be used to achieve this goal. If a business chooses the second choice, integrating various tactics for a significant increase in the total productivity would be quite difficult. The first alternative, a single productivity improvement plan, will make it possible for the business to increase productivity with the same or greater success. The only difficulty with this strategy is locating the probable problem area and then using process improvement techniques to achieve the anticipated dramatic increase in productivity. Business process reengineering refers to any significant adjustment of business processes that results in a dramatic increase in an organization’s productivity. Price, quality, after-sales support, adherence to delivery schedules, technological breakthroughs, etc. are some elements that influence market competition. Therefore, the business should focus its efforts on each of these areas in order to achieve notable improvements in terms of decreased operating costs and higher sales revenue from the sale of its goods and services to clients. Improved pricing for a company’s goods or services can provide it an advantage over competitions. Applying various cost-cutting strategies to lower variable costs and overhead costs will lower the price of the good or service. The other elements, viz. quality, after-sales support, delivery schedule adherence, and technological advancements are all directed in this direction

Introduction

GIS (Geographical Information System) based mapping takes cogence of three major geometrical dimensions, point, line and polygons and in GIS these three features correlate their relationship through a concept called Topology. Among the various applications where covariate processing requires specific attention, the landuse/ land cover and Digital Elevation Models/surfaces or terrains are the major area of interest. Use and processing of data for these covariates carries importance as accuracy of both these aspects would influence the derivatives extracted out of them further. For example, if landuse is improperly defined, the site for which planning is proposed may not sustain, similarly, point data/elevation data in case of DEMs would decide the exact topography of any landforms for their further utilization. For their use in GIS, while DEMs depend upon point data, the landuse/ land cover will be taken care by polygons. For the purpose of the study, we are going to discuss about these two covariates in the following paragraphs.

Generally, Covariate (covariable) (koh-vair-iãt) in statistics is defined as a continuous variable that is not part of the main experimental manipulation but has an effect on the dependent variable. In other words, as per ANCOVA (Analysis of covariance) definition: a covariate is a control variable.

Aim of the Experiment: The composite soil samples, collected, are air-dried and processed before analysis in the laboratory.

Plant nutrients are naturally components of the soil orchestrated by weathering processes and that the abundance of these metals in our soil environment now-a-days is due to numerous anthropogenic activities. In the environment, heavy metals are partitioned among the various environmental compartments such as water, soil, suspended solids and biota. Processes such as dilution, dispersion, sedimentation, adsorption and desorption govern their distribution. They also exist in colloidal ionic particulate and dissolved phases,  have a high affinity for humic acids, organic colloids and oxides coated with organic matter. The soluble forms are generally ions or unionised organo metallic chelates or complexes. The solubility of metals in soil and groundwater is predominantly controlled by pH, amount of metal, cation exchange capacity, organic carbon content, the oxidation state of the mineral components and the redox potential of the system.

Physical Properties of Soil

Physical properties of soil have many important roles in the crop production. The basic requirements for germination, seedling emergence and root development are adequate moisture and aeration, optimum temperature and absence of mechanical hindrance. After germination the further development of plant is also governed by physical conditions of soil. Soil texture, soil structure, soil density, soil consistence, soil water, soil air, soil temperature and soil colour are main physical properties of soils also affecting mechanical behaviour of soils. These are described here.

1. Soil Texture

The weathering divides larger particles of rocks and minerals in to the smaller ones. This process goes continuously. Thus, particles of different sizes ranging from large fragments of rocks to the very fine clay minerals are found in soil. However, for texture particles less than 2mm diameter is considered. The relative amount of these particles indicates the soil type also. Such as sandy soils contain more amounts of coarse particles i.e., sand and clayey soils are rich in fine particles. The rock and mineral particles having diameter less than 2.0 mm and come between specifies size are called as soil separates. International society of soil science (ISSS) and United States Department of Agriculture (USDA) systems are Generally, followed to classify the soil separates. This classification is given in table 3.1.

In India rice is cultivated under two land situations. In uplands, rice is grown under rainfed conditions and the yield is normally low. In medium or low land conditions rice is grown under wet condition where plenty of rain water or irrigation water is available. Here an intensive tillage is practiced in wet to create a soft puddle condition and then paddy is transplanted. Land submergence is thus an essential condition for successful rice cultivation.

Rice soils are not necessarily soils with water at or near the surface. Many soils have a fairly deep water table, but their surface is kept under submergence maintaining depth of 3-5 cm water. This condition is maintained either by puddling when wet or by having a compacted layer in the sub surface.

A rice soil is characterized by reducing conditions, when it is cropped with rice during wet season and oxidizing conditions during dry season, when the land remained fallow or planted with dry season crops if, irrigation water is available.

Introduction

Persistent income from agriculture is most important for sustaining the farming sector. Conservation agriculture (CA) is a resource-saving agricultural production system that aims to achieve production intensification and high yields while enhancing the natural resource base through compliance with three interrelated principles, along with other good production practices of plant nutrition and pest management (Abrol and Sangar, 2006). Conservation agriculture is largely promoted as one of the few win–win technologies affordable to farmers, in the sense that potentially it improves farmers’ yields (in the long term) at the same time conserving the environment. CA is described by FAO (http://www.fao.org.ag/ca) as a concept for resource saving agricultural crop production which is based on enhancing the natural and biological processes above and below the ground. As per FAO definition CA is to a.) Achieve acceptable profits, b.) High and sustained production levels, and c.) Conserve the environment. It aims at reversing the process of degradation inherent to the conventional agricultural practices like intensive agriculture, burning/removal of crop residues. Shifting from tillage-based agriculture to no-tillage CA systems removes unsustainable elements in the current tillage based systems and replaces them with CA elements that make the production systems profitable and ecologically sustainable. Conservation agriculture offers an opportunity for arresting and reversing the downward spiral of resource degradation, decreasing cultivation costs and making agriculture more resource – use-efficient, competitive and sustainable.

Since the 1960s, the world population has doubled from three to seven billion, and this trend will persist in the coming decades. Because of this rapid expansion, a massive increase in crop production is required to meet the food and energy demands of future generations. Potassium is the third important plant nutrient after nitrogen and phosphorous. It is seventh most abundant element in the lithosphere. Being chemically active metal, it is never found in its pure elemental state in nature. Potassium (K) plays a particularly crucial role in a number of physiological processes vital to growth, yield, quality, and stress resistance of all crops. The K content of Indian soils varies from less than 0.5–3.0%. The average total potassium content of those soils is 1.52% (Mengel and Kirkby 1987).

Introduction

Natural resources, especially those of soil, water, plant and animal diversity, vegetation cover, renewable energy resources, climate, and ecosystem services are fundamental for the structure and function of agricultural systems and for social and environmental sustainability, in support of life on earth. Historically the path of global agricultural development has been narrowly focused on increased productivity rather than on a more holistic integration of natural resource management with food and nutritional security. A holistic, or system-oriented approach, is preferable because it can address the issues associated with the complexity of food and other production systems in different ecologies, locations and cultures. Modern agriculture largely depends on the use of fossil fuel-based inputs, such as chemical fertilizers, pesticides, herbicides and energy intensive farm machinery. While the applications of such high input technologies have undoubtedly increased production and labour efficiency. There is a growing concern over their adverse effect on soil productivity and environmental quality which is emerging to recognize that the farmer has a great social responsibility as a land owner than merely agribusiness considerations. Therefore, there is need to develop agricultural techniques that are ecologically sound, economically viable, and socially responsible. Sustainable agriculture in the context of development helps to achieve production efficiency, protect ecosystem functions, enhance resilience to climate change, ensure healthy communities, satisfies basic needs and ensures optimum use/conservation of natural resources. Organic/biodynamic farming is among the various types of sustainable agriculture. Traditionally these methods has been playing very vital role in the conservation of natural resources in terms of soil health sustenance, environmental protection, food safety, waste recycling, biodiversity conservation with an economically viable approach. The chapter discusses the role of organic/biodynamic agriculture in natural resource conservation.

Protected cultivation provides controlled or modified growing environments that enable horticultural crops to be produced beyond their normal climatic limitations. This chapter covers greenhouses, polyhouses, shade nets, insect-proof structures, tunnels, and other protected systems. It explains environmental factors such as temperature, humidity, light, ventilation, carbon dioxide, irrigation, and fertigation. Protected cultivation can improve productivity, quality, resource-use efficiency, and production timing while reducing exposure to adverse weather and certain pests. The chapter also discusses crop selection, substrate culture, automation, and integrated management. Proper environmental control and economic planning are essential because protected systems involve higher initial investment but can generate high returns through quality produce and extended market opportunities.

Key words : copyright, patent, GIS, software, data sharing

1.0 Introduction

The copyright Act 1957 was mainly amended in 1994 and1999 to bring into complete harmony with Trade Related Aspects of Intellectual Property Rights (TRIPs), further major amendment has been done in 2012, that include wide range changes in ownership, term of protection, copyright security, cinematography and broadcasting provisions. In the same year government of India has initiated ‘National Data Sharing and Accessibility Policy (NDSAP)’ which came into operation from February 2012. At present the copyright Act and data sharing policy are the two legal and administrative instruments which facilitate the intellectual property protection and appropriate sharing among stakeholders in the country.

The intricate relationship between weather, climate, and agriculture dictates food security and the livelihoods of countless communities across the globe. In this context, public awareness of agricultural meteorology – the science of how weather and climate impact agricultural practices and outcomes – is not merely informative; it is transformative. This chapter delves into the critical role of fostering understanding and knowledge of agrometeorological principles among the broader public, with a particular focus on empowering farming communities. By exploring the significance of making weather and climate information accessible, relevant, and actionable, we will examine the strategies, initiatives, and global efforts aimed at building a weather-literate agricultural sector (Fig. 15.1). Ultimately, enhanced public awareness in this domain equips individuals and communities with the tools to make informed decisions, mitigate risks, adapt to changing climatic conditions, and contribute to more resilient and sustainable agricultural systems worldwide.

Background and Technology intervention

Instead of open channel irrigation, intervention of PVC pipeline system using gravitational hydraulic pressure can convey efficient water without the use of power. This will reduce conveyance loss and improve timely and equitable distribution of water to all farmers. As large number of open wells with pump sets are available, uninterrupted power supply is not available for on time irrigation during summer seasons. During such times, savings from tank water will be more helpful allowing the farmer to manage groundwater greatly.

Biofertilizers are one of the important components of organic farming and sustainable agriculture. Awareness among farmers is increasing on the biological fertilizers. But, the success of biofertilizer inoculation depends on the quality of the inoculant used. Because farmers are unable to judge the quality of the inoculants at the time of purchase or even at use. The inoculant producers are negligent to institute quality control programmes. Unfortunately much of the inoculant produced in the world today is relatively of poor quality. In such situation maintaining high quality inoculant products depend on the internal implementation of effective quality control systems by manufacturer. A major goal of a quality standard is to control the quality of inoculant to be used in any country.

Quality Control addresses the standards and management practices required to ensure reliable and effective biofertilizer products. It introduces general quality concepts, quality-control parameters, microbial functions, and properties of microbial products. The chapter then explains quality-management procedures for important biofertilizer groups, including Rhizobium, nonsymbiotic nitrogen fixers, arbuscular mycorrhizal fungi, and phosphate-solubilizing bacteria. Quality-control measures are linked to product performance, consistency, storage, and application suitability. By emphasizing systematic assessment and management, the chapter highlights why quality assurance is essential for maintaining viable microbial populations and delivering predictable agricultural benefits from biofertilizers and related biological inputs. across production and distribution systems effectively today.

Introduction

It is necessary to ascertain the quality of irrigation water so as to gauge the possible effects of this water on the soil. The irrigation water often results in water logging, salinity and alkalinity problems. It is therefore very important to know its quality. Following are the basic criteria or characteristics on which irrigation water quality is judged.

1. Presence of total soluble salts in irrigation water.
2. Proportion of carbonates and bicarbonates in relation to calcium and magnesium in irrigation water.
3. Proportion of sodium in relation to other cations in irrigation water.
4. Concentration of specific ions in irrigation water.

Several parameters are employed to judge the quality of irrigation waters No parameter in complete in judging the quality of irrigation water. Further the quality of water should be judged by considering the crop and soil factors. Any judgment without considering the above factors may not be useful. Researchers devised many parameters by following above said criteria. Some of the commonly adopted parameters used to judge the quality of irrigation water are:

Whatever may be the source of irrigation water viz., river, canal, tank, open well or tube well, some soluble salts are always dissolved in it. The main soluble constituent in water are Ca, Mg, Na and K as cations and chloride, sulphate bicarbonate and carbonate as anions. However ions of other elements such as lithium, silicon, bromine, iodine, copper, cobalt, fluorine, boron, titanium, vanadium, barium, arsenic, antimony, beryllium, chromium, manganese, lead, selenium phosphate and organic matter are also present. Among the soluble constituents, calcium, sodium, sulphate, bicarbonate and boron are important in determining the quality of irrigation water and its suitability for irrigation purposes. However other factors such as soil texture, permeability, drainage, type of crop etc., are equally important in determining the suitability of irrigation water.

The following are the most common problems that result from using poor quality water.

The quality of irrigation water has a direct influence on soil properties, crop growth and the long-term sustainability of irrigated agriculture. Water containing excessive salts or undesirable proportions of specific ions can create salinity, sodicity and other soil-related problems. This chapter presents the major criteria used for evaluating irrigation water quality. Salinity hazard is considered as an important indicator of the potential for salt accumulation in the soil and consequent restrictions on plant water uptake. Sodium hazard is examined because excessive sodium can adversely affect soil structure and permeability. The chapter also considers the salt index as a measure relevant to the evaluation of irrigation water. Bicarbonate hazard is discussed in relation to the chemical behaviour of irrigation water and its potential effects on soil conditions. Magnesium hazard is another important consideration in assessing the suitability of water for irrigation. By bringing these criteria together, the chapter provides a framework for evaluating irrigation water before application. Proper assessment of water quality is essential for selecting appropriate management practices and preventing long-term degradation of irrigated soils.

Water used for irrigation contain some salts, but quantities and kinds vary greatly depending on the source of water. Since sodic status of soils can be greatly influenced by salts in irrigation waters, successful irrigation practices require the evaluation system to judge irrigation water quality and methods employed. The actual damage done by salt to plants or soils depends on the concentration in soil solution rather than the quality of irrigation water applied. Thus, the use of some water source for irrigation might lead to severe salt problem in soils where drainage is restricted.

Criteria for evaluation of irrigation water

Various criteria considered in evaluating the quality of irrigation water are:

1. Salinity hazard

The most satisfactory method for rating the salt content of irrigation water involves measuring electrical conductivity. Various conductivity limits have been proposed to indicate the degree of salinity problems that might be anticipated with use of irrigation water on crops. There are four classes of salinity hazard such as C₁, C₂, C₃, and C₄.

1. Introduction
Ecosystem Services (ES) are actually the benefits human beings derive from their interaction with nature (Reyers et al., 2013; Ernstson, 2013). Around 400 BC, Plato observed how important service provided to Attica by the forests and subsequent loss of forests lead to drying spring and soil erosion (Mooney and Ehrlich, 1997). Thus, the work of Plato highlights that how the people were even then aware of the critical services provided by nature much before the industrial revolution (Rapidel et al., 2011). These ES are categorised into mainly provisioning, supporting, regulating and cultural services as per the Millennium Ecosystem Assessment (MEA, 2005). In fact, the increasing population warrants more and more set of ES (Biggs et al., 2015). A combination of factors responsible for delivery of ES like geology, climate, ecosystem, management scenarios, society, techniques, skills etc. that led to ES in an agricultural ecosystem (Kroll et al., 2012; Swinton et al., 2007). The ordinary nature largely comprised of agricultural lands (i.e., intensive crops, species poor, artificial pasture) that covers around 37.4% of total Earths’ land surface (FAOSTAT, 2016; Leff et al., 2004). Converting large tract of pristine lands into agricultural land and other competing uses considered to be one of the main reasons for biodiversity loss and land degradation (Tilman et al., 2001). Thus, meeting the challenge of working with limited arable land to feed our population in an eco-friendly manner requires our proper understanding of processes/mechanisms involved in nutrient availability/dynamics including fixation/ release pattern and refining the best management practices (Kumar et al., 2022a). The production of food has been targeted at the cost of other ES like supporting, cultural and non-marketable provisioning services (Muller et al., 2016; Foley et al., 2005; MEA, 2005). There is complex interaction between ecosystem and societal changes in an agricultural landscape. One is intermittently connected to other. Thus, it requires thorough understanding of the processes and biophysical factors that affect ES research, in particular and social-ecosystem, in general (Reed
et al., 2013; Carpenter et al., 2006; Plieninger et al., 2013). The ES that contribute to the agricultural production are mostly linked to aspect of soil fertility, biological control as well as pollination (Bommarco et al., 2013; Duru et al., 2015).
