NITROGEN (N) DEFICIENCY

Symptoms

Plate 308. Entire plant appearing light green. (Photo by Dr Prakash Kumar and Dr Manoj Kumar Sharma.)

1. Nitrogen deficiency is usually found during the initial stages of crop growth when root symbiotic nitrogen fixation nodules are yet to develop.

2. Nitrogen deficiency may also occur during later stages of crop growth when the symbiotic nitrogen-supplying mechanism is disturbed for some reason such as nodule infestation, nodule pathogenic disease or physiological causes.

3. Nitrogen is mobile in plants and under short supply conditions it is easily mobilized from older to younger leaves. The deficiency symptoms appear first and more severely on old leaves (Plate 307).

4. In mild deficiency conditions or when deficiency occurs in the young stage, the entire plant appears uniformly light green in colour (Plates 308 and 309).

5. If deficiency persists and becomes more severe, the older leaves show uniform pale green to pale yellow chlorosis (Plate 307).

6.1 Introduction to the Plant Cuticle

The primary barrier between the atmosphere and the aerial parts of higher plants is the cuticular membrane or the cuticle.

The constituents of this hydrophobic extracellular membrane, typically comprised of soluble waxes and polymerized lipids, are produced and secreted by the plant’s epidermal cells (Kunst and

Samuels, 2003; Pollard et al., 2008).

Lipids consisting mostly of C16 to C20 fatty acids are polymerized to form a matrix known as cutin (Schreiber, 2010).

The cutin matrix is both embedded with waxes (intracuticular) and covered with a thin layer of surface (epicuticular) waxes

12.1  Introduction

Mainstreaming sustainable agriculture systems in South Africa has become imperative. Severe environmental degradation, low farm profitability and poverty associated with current conventional production systems have brought the agricultural sector to a crossroads. If farmers in South Africa are offered a better chance to survive on the farm and if sustainable and economically viable agriculture is to be achieved, then the paradigms of agricultural production and management must be changed.

Conservation Agriculture (CA) 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. CA is characterized by three linked principles (FAO, 2001; Lal, 2010), namely: (i) continuous no or minimum mechanical soil disturbance; (ii) permanent organic soil cover; and (iii) diversification of crop species grown in sequences and/or associations, including the use of cover crops.

Introduction

In recent years, ‘an improvement in economic indicators throughout Africa led some observers to argue that the region had finally solved its economic conundrums and could now expect sustained economic growth’ (van de Walle, 2001). That optimism was fuelled by the end of several civil wars, a wave of democratization in several countries (which made possible the creation of the New Partnership for Africa’s

Development, or NEPAD, and a new agenda for development), the acceleration of economic growth, and significant improvements in the performance of the agricultural sector across Africa during the 1980s and

1990s. Output growth in sub-Saharan Africa

(SSA) from 1964 to 1983 was on average

1.8%, with the worst performance occurring between 1972 and 1983, when output growth was less than 1%, below the rate of increase in the use of inputs in agriculture

Abstract—Running multiples experiments in Software Engineering introduces the need of recording data as well as transferring knowledge across them, especially considering that several researchers are involved on replicating experiments. For that, experimental evaluations generate knowledge that must be registered into a so-called lab package. Researches have reported difficulties on sharing lab packages due to lack of standardization.

In this paper we present a tool to support experimenters to conduct controlled experiments, packaging experimental data.

2 Concepts and Mechanisms

Concepts and Mechanisms

The concept of botanically derived insecticides has gained favour in recent years, due in part to the perception that, because they originate from plant material, they are safer or ‘natural’.

These pesticides are often used for growing crops organically, according to guidelines set by certification programmes. However, it is important to be aware that they are pesticides, and that they fall under the same state and federal regulations as synthetic pesticides. In fact, plant-based insecticides have advantages as well as disadvantages. The advantages are that:

(i) they degrade rapidly and therefore are less persistent in the environment with reduced risks to non-target organisms, and may be applied shortly before harvest without leaving excessive residues; (ii) their action is rapid

(i.e. they may stop feeding by insects quickly or may cause paralysis); (iii) they have low mammalian toxicity; (iv) they are selective; and

(v) they are less phytotoxic than synthetic pesticides. However, there are disadvantages too, such as rapid degradation; possible toxicity in some cases for the user; cost and availability; and lack of toxicological data that are necessary for long-­term use and establishment of tolerances.

SETTING OUT

WORKS

CHAPTER

20.1 INTRODUCTION

Whereas surveying is the process of producing a plan or map of a particular area, setting out begins with the plan and ends with some particular engineering structure correctly positioned in the area. Most of the techniques and equipment used in surveying are also used in setting out.

It is important to realise that setting out is simply one application of surveying. In many cases, insufficient importance is attached to the process of setting out, and it tends to be rushed to save time. This attitude may result in errors, causing delays which leave construction machinery and plant idle, resulting in additional costs.

There are two aims when undertaking setting out operations:

1. The structure to be constructed must be set out correctly in all three dimensions—both relatively and absolutely, so that it is of correct size, in the correct plan position and at correct level.

2. The setting out process, once begun, must proceed quickly, without causing any delay in construction programme.

TOPOGRAPHIC

SURVEYING

CHAPTER

10.1 INTRODUCTION

Topographic surveying is the process of determining the positions, both on plan and elevation, of the natural and artificial features of a locality for the purpose of delineating them by means of conventional signs upon a topographic map. By topography is meant the shape or configuration of the earth’s surface. The basic purpose of the topographic map is to indicate the three dimensional relationships for the terrain of any given area of land. Thus, on a topographic map, the relative positions of points are represented both horizontally as well as vertically. The representation of the difference in elevation is called the relief. On a plan, the relative altitudes of the points can be represented by shading hachures, form lines or contour lines. In addition to the relief, the topographic map depicts natural features such as streams, rivers, lakes, trees etc. as well as artificial features such as highways, railroads, canals, towns, houses, fences and property lines. The topographic maps are very essential for the planning and designing of the most engineering projects such as location of railways, highways, design of irrigation and drainage systems, the development of water power, layout of industrial plants and city planning. Topographic maps are also very useful in directing military operations during a war.

20 Climate Change and Soil Carbon Impacts

Climate Change and Soil

Carbon Impacts

Pete Smith*, Pia Gottschalk and Jo Smith

Abstract

Soils contain vast reserves (~1500 Pg) of carbon (C), about twice that found as carbon dioxide in the atmosphere. Historically, soils in managed ecosystems have lost a portion of this C (40–90 Pg) through land-use change, some of which has remained in the atmosphere. In terms of climate change, most projections suggest soil C changes driven by future climate change will range from small losses to moderate gains, but these global trends show considerable regional variation. The response of soil

C in future will be determined by a delicate balance between the impacts of increased temperature and decreased soil moisture on decomposition rates, and the balance between changes in C losses from decomposition and C gains through increased productivity. In terms of using soils to mitigate climate change, soil C sequestration globally has a large, cost-competitive mitigation potential. Nevertheless, limitations of soil C sequestration include time limitation, non-permanence, displacement and difficulties in verification. Despite these limitations, soil C sequestration can be useful to meet short- to medium-term targets, and confers a number of co-benefits on soils, making it a viable option for reducing the short-term atmospheric CO2 concentration, thus buying time to develop longer-term emission reduction solutions across all sectors of the economy.

Summary

Caenorhabditis elegans is susceptible to three domain crystal proteins similar to those that intoxicate insects. Investigations of this organism have several important strengths, for example, ease of forward genetic screens, range of molecular genetic tools available and ease of carrying out RNAi (RNA interference) studies. These have been exploited to study cellular responses known as cellular non-immune defences (CNIDs) to the crystal proteins of Bacillus thuringiensis (Bt) and pore-forming toxins in general. We will discuss what we have learned through genetics and RNAi

(including genome-wide RNAi) to elucidate the pathways that allow cells to respond productively to crystal protein attack. In addition, key results will be discussed from investigations with mammalian poreforming proteins to highlight the conservation of cellular responses to crystal proteins with cellular responses to poreforming proteins in general.

BIOINFORMATICS AND

COMPUTER APPLICATIONS

BIOINFORMATICS : INTRODUCTION

It is the science of using information to understand biology. It is conceptualizing biology in terms of molecules and applying informatics techniques (computer science, applied mathematics and statistics) to organize the information associated with these molecules. Bioinformatics and data mining are two latest areas of research involving computer-assisted management of data generated for biotechnology applications. The information generated in genomics is enormous and its interpretation requires the use of powerful computers and specific softwares.

Computer Network

The internet is a global network of computer networks that link government, academic and business institutions. Computer within the network are referred to as nodes and these communicate with each other by transferring data packets. Each computer or network mode has a unique address (IP address) by which it can be identified and can communicate with other nodes.

ur perceptions or attitudes toward things are not always rational and are often culturally influenced. They are a combination of thoughts or the cognitive dimension, feelings, or the affective dimension, and the way we react—the behavioral dimension. The cognitive dimension consists of things we know, the affective dimension comprises of things we feel, and the behavioral dimension is how we will act on the attitudes we build. Attitudes help us to become socially acceptable; belonging to a group is very important, and it gives meaning to things we experience.

Advancements in science and technology have made our life very simple and fast. At the same time some of this advancement has caused great concern regarding the long-term impacts on environment and life. In 1985, the World Commission on Environment and Development (WCED), also known as Brundtland Commission appointed by United Nations (UN), recommended sustainable development preserving the environment without any degradation. The Commission defined sustainable development as ‘the development that meets the needs of the present without
