Introduction

Droughts are considered to be a significant environmental disaster and have captured the attention of various experts, including environmentalists, ecologists, hydrologists, meteorologists, geologists, and agricultural scientists. These natural calamities are known to occur in almost all climatic zones, regardless of whether they are high- or low-rainfall areas. Generally a decrease in the amount of precipitation received over an extended period such as a season or a year, is the primary cause of droughts. However, other factors such as high temperatures, strong winds, low relative humidity, and characteristics of rainfall (e.g., intensity, duration, onset, and termination) also play a crucial role in their occurrence. It’s important to distinguish a drought from aridity, which is a permanent feature of a climate and is limited to low rainfall areas (Wilhite, 1992). A drought is a temporary phenomenon and can last from a few months to several years. Some people often mistake droughts for heat waves, but Chang and Wallace (1987) highlighted the fundamental difference between these two events. A heat wave typically lasts for a week, while a drought can extend for several months or even years. When a heat wave and a drought coincide, it can lead to dire socio-economic consequences.

To overcome the challenge of popularizing pigeonpea hybrids in the country, it is considered fair enough to compare the hybrid rice with respect to their seed production technology, yield advantages and profitability to the farmers and seed producers. Since both pigeonpea and rice are grouped under self-pollinated crops, this comparison, in the views of authors, may help in encouraging hybrid pigeonpea seed producers and those involved in marketing of hybrid seed.
  
Rice is a highly self-pollinated crop and earlier hybrids were not possible because it was essential that large quantities of hybrid seeds are produced easily and economically. In China, the birth place of hybrid rice, this impossible looking task was accomplished. To launch this program, the Chinese scientists decided to alter the pollination system of rice.

The affections of abdominal cavity incidence wise are on the top followed by thoracic cavity. Both these affections lead to high morbidity and heavy mortality losses. Most thoracic affections produce almost similar clinical signs but abdominal affections can show different clinical signs. Radiography and ultrasonography play an important role in differentiation and confirmation of various affections.

Radiography is an important diagnostic tool for both thoracic and abdominal diseases in small animals but for large animals it is more useful for thoracic affections as compared to abdominal affections. In large animals, the use of radiography is limited up to the ventral aspect of the abdomen only i.e. for diagnosis of diseases of reticulum, diaphragm and sternebrae. In thoracic cavity, there are numerous diseases that need to be differentiated. Pneumonia, lung cyst, lung abscesses, pleuritis and pleural effusions are some important diseases apart from presence of foreign bodies. In such a situation, radiography can play an important role as an aid in the diagnosis of various affections.

Similarly ultrasonography has also played a major role in the diagnosis of abdominal diseases in small animals such as dogs and newborn calves especially in the field of G I tract and urinary system. The ultrasonography is advantageous over radiography in the sense that internal anatomy of the soft organs can be better known and studied by ultrasonography as compared to radiography. It is also considered to be extremely safe for both the patient and the operator.

14.1. Characteristics of Social Entrepreneurs Compared to Corporate Entrepreneurs

Prior research has found many parallels between social and commercial entrepreneurs when it comes to personality and behavioural traits (Drucker, 1989; Gitman & McDaniel, 2008; Gordon, 2006). There are some essential personal characteristics of these entrepreneurs that contribute to the success of the venture. A recent empirical study conducted by Sharir and Lerner (2006) identifies eight variables that contribute to success of a social venture. Out of these eight variables, five are directly related to the qualities of the entrepreneur, namely, the entrepreneur’s social network , commitment , previous management experience, ability to integrate the vision and to establish strategic alliances . Similarly, a study of the characteristics of social entrepreneurs in the United States found that social entrepreneurs are more likely to have high social capital (Ryzin, Grossman, DiPadova-Stocks & Bergrud, 2009). Although such studies of the personal characteristics of social entrepreneurs provide useful information about the leadership and organisational skills of such individuals, they do not explain the essence of these traits, why they are important and how social entrepreneurs use them to achieve their social mission and create and sustain social change. More research is required to understand what values, motives and behavioural repertoires distinguish a social entrepreneur from a corporate entrepreneur.

The food plants of world are damaged by more than 10,000 species of insects, 30,000 species of weeds, 1,00,000 diseases (caused by fungi, bacteria, viruses and other microorganisms and 1000 species of nematodes (Hall, 1995). The global losses due to various categories of pests vary with the crop, geographic location and weather. Total yield losses from different pests to all the crops have been estimated to be US$ 500 billion worldwide (Oerke et al., 1994). In India, the current losses due to insect pests in principal field crops have been estimated to be Rs. 6, 89,400 million (Dhaliwal et al., 2004). In addition, there is loss of Rs. 60,000 million due to insect pests during storage. Thus, total losses to major crops and food grains in storage caused by insect pests are estimated to be Rs. 750 billion annually (Dhaliwal and Arora, 2006). Among regions, losses in Asia and Africa almost reaches 50 percent whereas in Europe (28.2%), North America (31.2%) and Oceania (36.2%) are below average. Losses due to animal pests in Asia (18.7%) are almost double those in developed countries and losses from weed competition in Africa and Asia are approximately double than those in Europe (Oerke et al., 1994). To combat such heavy losses mostly chemical pesticides are used by the farmers but indiscriminate use of pesticides has led to severe ecological consequences like destruction of natural enemy fauna, effect on non target organisms, residues in consumable products including packed pure and mineral water and ultimately resistance to the pesticides, to which we solely rely. Insecticides are always required to suppress rapidly expanding insect pest populations. Strategies should be employed to increase efficiency and accelerate insect mortality by combining microbials with sub lethal doses of chemical insecticides and botanicals. Biointensive pest management (BIPM) is the recent trend in Indian farming and attracting the farmers for higher income to their produce. This has resulted due to increased awareness among the end users and concerns about the deteriorating ecological situations among the eco-campaigners.

Microbial pesticides consist of disease causing microorganisms, which are disseminated in the pest populations in large quantities in a manner similar to application of chemical pesticides. It includes bacteria, viruses, fungi, nematodes and some protozoans. Pathogens may exert controlling effect by means of their invasive properties, toxins, enzymes and other substances (Lewis, 2006). The use of microbial insecticide has been proved to be a viable alternative to chemical insecticides, especially in management of forest insect pests. The combination of particular active ingredients and their ability of replication in host populations in the fields define the major differences between microbial insecticides and chemical insecticides. These differences have practical implications for their use in insect pest management programmes.

In a cropping systems there may be simultaneous or sequential application of herbicides, insecticides, fungicides, fertilizers, PGR during a single cropping season. The different chemicals will undergo physical and chemical changes as they interact with plant, soil and other chemical substances already applied to the plant or soil. The interaction effect of such chemical substances will be visible only at the later end of the cropping season. The responses observed in the plants can be.

Combining two or more pesticides in a tank saves time and labour while also lowering equipment and application costs. However, the effectiveness of one or more products may change in some circumstances. Two or more pesticides are compatible if they may be mixed and sprayed together without changing the efficacy, physical and chemical qualities of the mixture, or harming unwanted application locations. Chemicals are considered incompatible when issues arise when more than one product are mixed..

Incompatibility

Incompatibility occurs when a pesticide is unable to be adequately blended to generate a homogenous solution or suspension. Flakes, crystals, or greasy masses, as well as significant separation, are not acceptable. Incompatible mixes like this can clog application equipment and hinder the even distribution of the active ingredient in the spray tank. This inhibits pesticides from being applied properly.

Principle

Plasmids requires hosts to replicate, hence it has to be inserted into bacteria. But efficiency of uptake of plasmid DNA by bacteria is low and will not do so without getting degraded. Therefore, to enhance the probability of uptake of the plasmid DNA by bacteria it is necessary to make the bacterial cells “competent” to absorb the plasmid DNA. One of the methods to increase efficiency of cell competence is given below. It should be noted that competent cells are more fragile than normal bacteria. Vortexing the cells, heating the cells above 42ºC or to 42°C for prolonged periods, or exposure of the cells to abusive treatments may kill them

ABSTRACT

Academic libraries are unique, essential and strategic hubs inside our social cloth which are advanced primarily based totally at the requirements of the times, to help people in the purchase of good enough facts that could allow them to decorate their information, for the development in their wellness and that of the society at large. To attain their goal, they ought to generate, filter, control and diffuse correct and well timed human information which have been harvested and documented; for the purpose of enriching the highbrow needs in their clients. Like every other kind of library, academic libraries are growing organisms. Justification to the above statement has been captured aptly in the classic book of Ranganathan (1931) entitled ‘Five Laws of Library Science’; detailing the principles of the library profession. The philosophical postulation of Ranganathan’s fifth law is a classical position that offers much strength and support for the need to adequately plan for the best strategies to exhibit in academic library environments in order to provide effective services. In other words, the fore-stated law by Ranganathan has already signaled that academic librarians must be ready at all times to effectively satisfy the diverse, complex and ever-increasing information needs of their users from the explosive available information resources that spring on a daily basis. As such, addressing this issue would require a holistic management approach by academic libraries that must be internally efficient and externally effective.

6.1 Competition

Soil microorganisms in particular are perceived as active competitors that have evolved diverse strategies to facilitate resource acquisition. Activities including motility, coordinated behavior, and antibiotic production can tip the competitive balance, resulting in numerical dominance or local extinction of competing populations. Functional consequences of microbial social behaviors have been studied extensively and demonstrate the importance of factors such as relatedness, kin discrimination, enforcement of cooperation, and competition among relatives to microbial survival and f itness in the environment (Adil Essarioui et al., 2017). However, most investigations have focused on interactions among closely related taxa, often among species or genera. Yet, in natural environments, coexistence of individuals from diverse microbial phyla and kingdoms is common. In particular, bacteria and fungi commonly coexist in soil, but there has been relatively little study of the role of species interactions in mediating the dynamics of specific bacterial and fungal populations in soil. Moreover, we have little understanding of the extent to which the ecological context, and specifically plant host or plant community diversity, may influence bacterialfungal interactions in soil. Such studies are needed to begin to establish a more complete understanding of the ecological and coevolutionary dynamics of soil microbial populations.

Microbes have coevolved to engage in complex networks of interactions with coexisting kin and non-kin individuals in the soil and in association with plants. Microbial antagonism and resource competition within complex communities have been the focus of many studies that have explored the effects of diverse factors on the ecological outcomes of these interactions. However, the concurrent impacts on these processes of plant species richness and plant host, which jointly structure the environment within which rhizosphere microbes interact, have received far less attention. This is despite the fact that both plant community richness and plant species have been shown to impact microbial community composition and function in rhizosphere soil, with potential implications for microbial interactions and pathogen suppression in natural and agricultural habitats.

Introduction to Competitive Analysis

Competitive analysis is a crucial component of strategic planning and business decision-making. It involves assessing and understanding the competitive landscape in which a company operates. Here are some key points to consider when introducing competitive analysis:

Competitive analysis is the process of evaluating and analyzing the strengths and weaknesses of current and potential competitors in a specific market or industry.

Purpose: The primary purpose of competitive analysis is to gain insights into competitors' strategies, capabilities, and market positioning. It assists businesses in pinpointing opportunities, mitigating risks, and formulating effective strategies to surpass their competitors.

Information sources: Competitive analysis relies on gathering information from various sources. These include publicly available data, industry reports, competitor websites, customer reviews, social media, and market research.

The competitive relations among the cultivated crop species perform a relation and these are pronounced during the early growth period of the crops and during later phases. The crop’s performance is reflected into the yield output. Intercropping research so far conducted is based on the experimental layout of either replacement or additive series.

Introduction

It includes different levels of competitive strategy and how generic competitive strategies can be formulated. The organisation need to understand how to tackle the competitors and what specific decisions to be taken while formulating a competitive strategy. Each type of industry has to plan its own competitive strategy either to grow or to come out in bad situation. Michal Porter described generic competitive strategies to cope with five competitive forces. These strategies help organisation in different situation to develop appropriate competitive strategy that can be implemented effectively.

Competitive strategies are the methods and approaches used by companies to gain a competitive edge in the market and surpass their rivals. These strategies involve making deliberate choices about how to position the company, allocate resources, and respond to market conditions. Here are some key points to consider when introducing competitive strategies.
