Although thousands of plant species exist on the earth, only those that were found to be useful for humans as food, feed, fiber, timber and other utility materials have been selected for domestication. When these plant species were affected by various biotic and abiotic causes, the necessity arose to determine the ways and means of protecting the valuable plants species and to understand the host plant defense mechanisms and pathogenic potential of the microbial pathogens causing enormous losses to the cultivators. All plant species have built-in resistance to most microbial plant pathogens existing in the environment. Susceptibility of plants to some of them is an exception, since they are endowed with genes which effectively nullify the possible adverse conditions created by the microorganism. Likewise, microbial pathogens possess genes for survival and pathogenicity to survive in the absence of susceptible plant species and to successfully establish infection in suitable plant species. The microbial pathogens have evolved highly specialized tactics to overcome the defense responses and to rapidly multiply in plants for their survival and perpetuation in a geographic location / ecosystem

The increase in population and global industrialization has led to environmental pollution, which is a significant threat to the health of the ecological system. Different measures are recommended to remediate polluted areas effectively. The applications of nanotechnology in medicine, cosmetics, sports, textiles, and pharmaceuticals have increased over the years. Another approach to remediate the adverse effects of pollutants on the environment is by utilizing nanotechnology for contaminant remediation. Biogenic nanoparticles are tiny particles produced by biological entities such as fungi, bacteria, yeast, and algae. These biogenic nanoparticles are efficient in removing pollutants like heavy metals, pharmaceutical waste, dyes, and hydrocarbon waste. 

The reclassification of the order Rickettsiales was predicated upon comprehensive genetic analyses of 16S rRNA, groESL, and surface protein genes. Consequently, organisms within this order were systematically assigned to one of two families: Anaplasmataceae and Rickettsiaceae. Within the Anaplasmataceae family, phylogenetic analyses consistently delineated four genetically distinct clades: (1) Anaplasma, (2) Ehrlichia, (3) Wolbachia, and (4) Neorickettsia. Despite the obligate intracellular nature of rickettsial organisms in both families, those classified under Rickettsiaceae proliferate freely within
the host cell cytoplasm, whereas members of the Anaplasmataceae family are confined exclusively to membrane-bound vacuoles within the cytoplasm of host cells.
The first documented cases of anaplasmosis trace back to the late 19th century in South Africa. However, it wasn’t until 1910 that the causative agent of the disease was conclusively identified morphologically as “marginal points” within red blood cells by Max Theiler, later named it Anaplasma marginale. A year later, he identified another species, A. centrale, which caused a milder form of the disease in cattle. During the 1930s, Sanborn, Stiles, and Moc demonstrated the mechanical transmission of A. marginale by horse flies and stable flies. In the late 1980s, the life cycle of A. marginale was fully elucidated in ticks belonging to the genus Dermacentor.

Clinical laboratory tests used in the evaluation of disease states
Clinical laboratory tests are essential tools used in the evaluation of various disease states. They help diagnose conditions, monitor disease progression, and assess treatment effectiveness.
Haematological Test
Hematological tests are critical in diagnosing and managing various blood disorders and conditions affecting the blood and bone marrow. These tests provide essential information about the cellular components of blood, helping healthcare providers assess a patient’s health status and guide treatment decisions. Below is a detailed overview of common hematological tests, their purposes, and significance.
Common Hematological Tests
1. Complete Blood Count (CBC) Definition: A CBC is one of the most frequently ordered blood tests that evaluates several components of blood.
Components:
• Red Blood Cells (RBC): Measures the number of red blood cells, which carry oxygen.
• Hemoglobin (Hb): Indicates the oxygen-carrying capacity of the blood.
• Hematocrit (Hct): The proportion of blood volume occupied by red blood cells.
• White Blood Cells (WBC): Assesses immune function; elevated levels can indicate infection or inflammation.
• Platelet Count: Evaluates the number of platelets responsible for blood clotting. Purpose: The CBC helps diagnose conditions such as anemia, infection, leukemia, and other hematological disorders.

A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out routine operations. SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations. The military (e.g. in the U.S. and UK) sometimes uses the term standing (rather than standard) operating procedure because a military SOP refers to a unit’s unique procedures, which are not necessarily standard to another unit. The word “standard” can imply that only one (standard) procedure is to be used across all units. The term can also be used facetiously to refer to practices that are unconstructive, yet the norm. In the Philippines, for instance, “SOP” is the term for pervasive corruption within the government and its institutions.

One ofthe biggest issues the world is facing today is the lack of clean and pure water. Due to rising water demands, rigid health regulations, and xenobiotic pollutants, traditional wastewater treatment technologies cannot provide safe water. The present era necessitates innovative approaches to wastewater treatment technologies and improved water resource conservation and management materials. By utilizing innovative nanomaterial, nanotechnology guarantees a continuous provision of potable water and contributes to the preservation of water sources. Nanomaterials expedite rapid processes for the purification, conservation, and reuse of wastewater, complementing other enduring industrial methods. 

In India, we have mostly two types of standards, which govern the sale of foods including milk and milk products.

These are: Legal standards and Quality standards.

Legal standards

Legal standard means the specifications or the requirements which pertain to the law of the Govt. and are set up by the Govt. to meet certain minimum requirements in terms of chemical quality (i.e. composition), bacteriological quality (i.e. hygienic quality), and labelling and packaging requirements.

In our country, legal standards are given under Prevention of Food Adulteration (PFA) Rules, 1954-1955 (which are amended from time to time). Legal standards or PFA standards prescribe the minimum requirements for all types and categories of food. These standards are consistent with the minimum quality that is attainable under Indian conditions by the majority of the farmers, producers, processors, sale agencies etc. Further, any food that does not confirm to the minimum standards laid down by the legal rulers (PFA rules) is said to be adulterated, irrespective whether anything has been added to or removed from the original food.

Abstract

Food lost during the production chain is referred to as postharvest loss. Reducing postharvest loss can effectively feed starving mouths while conserving resources and decreasing the pressure to produce more. There are five main areas where postharvest loss can be reduced – harvest, storage, transportation, processing, and retail. New approaches and technologies in each of these areas will increase the amount of food available for human consumption. The total loss due to poor post- harvest processing of agricultural products in India when valued in terms of monetary reflects a tremendous loss in the economy. Annual value of harvest and post-harvest losses of major agricultural produces at national level to be of the order of Rs. 92,651 Crore calculated using production data of 2012-13 at 2014 wholesale prices. Deficits in food items or financial loss should not have occurred if postharvest losses were reduced through proper processing and preservation from harvest to consumption. Both the government and private sector need to invest in research so as to improve and modernize post-harvest facilities for attaining more efficient market infrastructure and distribution channels. Research and extension activities have to be closely coordinated particularly in the public sector for the benefit of farmers, traders and consumers.

There are number of internal and external factors that affect the production performance of animals, among which parasites and parasitism are major of concern constraints to animal’s productivity especially in tropical countries. Feed intake and nutrient requirements have been recognized for long time as an important parameter for determining the efficiency of animal production. Most of the parasitic infection in domestic animals is caused by gastrointestinal nematode, which may result in depression in appetite, impairment in GI functions, alteration in protein, energy and mineral metabolism and changes in water balance. Nutrition can affect the ability of the host to cope with the consequences of parasitism and to contain and eventually to overcome parasitism. Since it is proposed that the host gives priority to the reversal of the pathophysiological consequences of parasitism over other body functions, it is to be expected that improved nutrition will always lead to improved resilience. On the other hand, it is proposed that the function of growth, pregnancy and lactation are prioritized over the expression of immunity. Improved nutrition may affect the degree of expression of immunity during these phases and can thus influence the resilience and resistance of host to parasite infection.

Introduction 
It is commonly acknowledged that the swift rise in urbanization and population expansion is the primary reason for the increasing consumption of fossil fuels, which ultimately results in the exhaustion of fuels generated from petroleum. Globally, the scarcity of fossil fuels poses a significant challenge. Furthermore, there are significant worries about the negative impacts of the heavy reliance on petroleum-based fuels on the economy, energy and the environment conservation. Consequently, extensive research has been dedicated to identifying alternative sources that can mitigate the dependence on fossil fuels [1]. Biofuels have garnered worldwide attention as a potential substitute for fossil fuel-derived fuels, given their distinctive qualities [2]. Utilizing a variety of plant sources, including sugarcane, corn, soybeans, vegetables, palm oil, and Jatropha (often used in Africa), biofuel production is progressing on almost every continent. Bioethanol is successfully used as a biodiesel in addition to gasoline for otto-cycle engines in nations like the USA and Brazil [3]. Conversely, biodiesel represents a significant category of biofuel capable of partially or fully replacing diesel obtained from fossil fuels. Biodiesel is made via a process called trans-esterification that uses renewable biolipids [4]. Biodiesel can be produced from oil that comes from nonedible agricultural seeds or kernels [5]. Furthermore, edible oils from plants such as sunflower, palm, and soybean are used as feedstocks to produce biodiesel [6]. In the field of biofuel research, nanotechnology and nanomaterials have proven to be useful instruments for improving output quality at a reasonable cost. Algae stands out prominently in discussions about biofuel production due to concerns related to food resources. Types of biofuels and their sources are represented in the (Fig.1). The use of crops and plants yielding food is considered unsuitable for prioritizing biofuel production due to potential disruptions in food supply. Notably, various algal species vary in their production capacity. The utilization of nanoparticles (NPs) is advantageous in biofuel synthesis due to their unique characteristics, including a substantial surface area to volume ratio, adsorption capacity, high crystallinity, and stability. This distinguishes them from competing sources as better possibilities [7]. In the process of creating biofuels, metal oxide nanoparticles and carbon nanotubes are widely used as nano-catalysts because of their extra characteristics that allow for their high potential recovery [8]. The overall procedure for producing biodiesel on a small scale and for experimental purposes using algae are shown in the (Fig.2).

The North Eastern region stretches from 21°25' to 29° 28' N and 80° 4' to 97°25' E and covers a total geographical area of 2.55 lakh square kilometer sharing about 8 percent of the country’s geographical area. The NE states, otherwise known as eight jewels, which are Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura and Sikkim. This region is characterized by inaccessibility, marginality, fragility, cultural heterogeneity, ethnicity, rich bio-diversity, low livestock and crop productivity. These states are the reservoirs for genetic diversity of tuber crops like Colocasia, Xanthosoma, Alocasia, elephant foot yam, Dioscorea and other minor tuber crops. The annual precipitation in the region is about 2450mm and maximum rainfall is received from South West monsoon.

Introduction

Climate change is of great concern to India in view of food and nutritional security of its ever growing population. The impacts of climate change are global, but Indian subcontinent is more vulnerable due to dependence of its large population on agriculture. It can cause millions of deaths a year worldwide and costing more than a trillion of US dollar. Climate change has direct effect on agriculture due to 0.74°C average global increase in temperature in the last 100 years and atmospheric CO₂ concentration having increased from 280 ppm (1750) to 400 ppm (2013). These changes have direct effect on growth and multiplication/fecundity, spread and severity/infestation of many plant pathogens/insect pests, which in turn are affecting the pattern of incidence of pests (including diseases). Changing pest scenario due to climate change has warranted the need for future studies on such models which can predict the severity of important pathogens of major crops in real-field conditions. Simultaneously, pest management strategies may be reoriented to cope up with changing scenario for sustainable food production.

Background

Sheep and goats are the poor man’s cow because of the lower capital investment, and production costs. Also supplies milk quantities that are suitable for immediate household consumption thereby reducing problems of milk storage and marketing. Small ruminants, goats and sheep, mainly localized in the arid, semi-arid and mountainous areas of the country, have multi-faceted utility in terms of wool, meat, milk, skins, (mo)hair/pelts, manure and have also acquired socio-cultural niches in many communities (Kosgey and Okeyo, 2007). Goat and sheep milk has many advantages over other livestock species’ milk being easy in digestion, non-allergic, naturally homogenized, improves immunity as it has antifungal and anti-bacterial properties. However, rearing small ruminants for meat is more popular among farmers as price of chevon and mutton are very high, continuously increasing over the years and sale of male for meat is easy, steady and accessible at farmer’s place or local places unlike milk, skin and fibre. Thus, small ruminants (SR) occupy a promising agrarian and economic niche in low to medium input production systems, not suitable for growing crops and dairy farming (Devendra and Chantalakhana, 2002), mostly driven by small and marginal farmers and landless laborers. Their meat and milk production represents 4.8% and 3.4% of the total meat and milk produced, respectively, in the world.

7.1 Learning Objectives
After comprehending this unit, we will be capable to:
i) Understand the conception of regression;
ii) Appreciate the significance of regression;
iii) Understand the difference between regression and correlation;
iv) Know about the regression lines;
v) Anticipate the difference between simple regression and multiple regression.

7.2 Introduction

Correlation is followed by linear regression. Regression is applied for forecasting the value of an unknown variable with the help of a known variable. The forecasted variable is called the dependent variable. On the contrary, an independent variable is used for forecasting the value of a dependent variable. If you desire to know, for instance, if exam achievement can be anticipated based on review time, whether cigarette consumption can be predicted based on smoking length, and so on, you may use linear regression. You must utilize multiple regressions if we deal with more than one independent variable rather than simply one.

Different crops are grown over a wide range of agroecosystems. Though the crops are raised in varied climates, ranging from very hot to very cold, and very wet to very dry, across temperate, tropical and semiarid zones, they are very sensitive to climate. The crop production is dependent on climatic parameters like rainfall, light, temperature, relative humidity and carbon dioxide concentration. Each kind of cultivated crop plants has its own optimum growth requirements. Breeding and selection of new cultivars have allowed for a greater adaptability to less favourable growing conditions than was possible in the past, but the inherent climatic requirements of a specific kind of crop have not changed materially.

CLIMATIC NORMALS FOR CROPS

Crop management is very much about managing climate risk so as to have financially viable and sustainable agricultural systems. Professor Henry Nix of the Australian National University posed three questions that need to be addressed when considering what crop can be grown where (Nix, 1981).

1. For any given crop which areas offer the greatest biophysical advantages?
2. For any given area which crops offer the greatest advantages?
3. For any given crop and area how much productivity be raised and sustained?

Introduction

Pulse production in India has fluctuated widely with no long-term trend, leading to a steady decline in per capita availability per day, i.e. from 60.7 grams to 33.40 grams during 1951 to 2001, while its average requirement is about 65 gram per day per head. The pulses used to serve a low cost food to meet the protein requirement of a large sector of people in India. But, the pulses are becoming out of reach for the common people of country because of its continuing shoring prices. A Technology Mission on Pulse production was launched by Government of India in 1986-87 as a special drive to increase the pulse production in the country. The vision of Technology Mission of Pulse is attaining self reliance in pulses for household nutritional security and sustainability of the production system. The mission statement was to increase Pulse production from existing (IX plan) 131.4 lakh tonnes to 162 lakh tonnes; Productivity from 594 kg/ha to 702 kg/ha and per capita availability of pulses from 35 g to 40 g per day at affordable price. Unfortunately, the country has not been able to achieve self-sufficiency in the pulse production. During the last 40 years, the acreage under pulse crops and its production remained almost between 21-24 million hectares and 10-15 million tonnes, respectively. Consequently, the country has had to depend on import of pulses every year to meet the part of its shortage. The National Commission of Agriculture had estimated that the country should plan to produce about 25 million tonnes of pulses by the end of 2000, but we could achieve only about 14 million tonnes. Presently, the area and the production of pulse crops account for about 18.50 and 7.20 per cent (2003-04) of total area under foodgrains and total food grains production in the country, respectively.

Pomology: Pomology is a branch of horticulture that deals with the cultivation of fruit crops. When given a liberal and flexible translation, the word “pomology” means the science of fruit. The term is derived from the Latin word pomum, which means “Fruit” and the Greek term logy, which means “Science.

Fruit

“A true botanical fruit is defined as a mature or ripened ovary with or without accessory organs.” Classifcation refers to the grouping of individuals with similar identities, related in genetic make up, evolution or climatic requirements. The major units of classification are order, family, genus, sub family, species, variety/cultivars and clone or strain. All fruit crops bear flower and seed (spermatophyte) and belongs to class Angiosperm except in (Pinus gerardiana) of gymnosperm.

Most of the fruits are covered under the dicotyledonous families of Angiosperm except banana, pineapple, date and coconut which belong to monocotyledonous families e.g. Musaceae, Bromeliaceae and Arecaceae (Palmae) respectively. The families of economically important fruits include Rosaceae (all pome, stone fruits and strawberry), Rutaceae (citrus fruits, bael and woodapple), Musaceae (banana and plantain), Vitaceae (grapes and Anacardiaceae (Mango, cashew and pistachio nut, hog plum) etc.

Abstract

Various cropping systems and ecologies illustrate the positive use of chemicals both as fertilizers and pesticides and organic/biological sources within the frame work of Integrated Plant Nutrition and Plant Protection System (IPPS). While considering the organic/biological sources, green manures seem to be the best alternative that may largely suffice to the organic matter requirements of the soil under crop cultivation. Green manuring can be defined as a practice of ploughing or turning into the soil undecomposed green plant tissues for the purpose of improving physical structure as well as fertility of the soil. “Green manure” refers to fresh plant matter, which is added to the soil largely for supplying the nutrients contained in its biomass. The agricultural practices consisting of growing and ploughing under a green crop or addition of a green organic matter in the form of leaves and other succulent parts from outside to improve soil productivity is known as green manuring. In this review, advantages of green manuring, decomposition of green manure,   process of decomposition, factors affecting decomposition and effects of green manuring have been discussed in detail.
