Introduction

Increasing use and rise in the cost of chemical fertilizers, pollution due to their application and decline in soil fertility and micro flora are worrying facts to the farming community. Increased awareness about organic produce among the consumers is another reason to find out an alternative to chemical fertilizers. Vermicompost production on farm and its use in crop production is one way of mitigating these problems. Among the different methods, Windrow method of vermicomposting is the production of compost by piling organic matter or biodegradable waste, such as animal manure and crop residues as long rows (Windrows) on the surface of soil under the shade of trees without any permanent structures and later releasing required quantity of earthworms in wet beds. This vermibed technology is simple and cost effective and sustainable to adopt.

The prototypes have been exhibited in the premises of Dairy unit, University of Agricultural Sciences, Dharwad since long and many farmers seeing these were of the opinion that technology was simple and easy to adopt using the farm generated biomaterial waste with no additional cost. During 2020-21, when farmers of remote villages Dharwad district were interacted, it was noticed that still the technology was not followed by the farmers.Therefore, a team of Green Foundation based in Dharwad made an attempt to reach the farmers of remote villages of Dharwad district to make aware of this technology. After interactions with different categories of farmers, a modest attempt has been made to identify small and large farmers of remote villages viz. Basavarsikoppa and Holtikoti of Dharwad district during 2021-22 to sensitize and demonstrate windrow method of vermicompost production. The results, experiences of the farmers and finally the impact of the technology are discussed here in this presentation.

Wool, which is sourced from sheep, is a significant protein fibre categorized as an animal fibre. Its hygroscopic nature allows it to absorb moisture effectively. Composed mainly of keratin, a protein created by amino acids linked through peptide bonds, wool possesses unique characteristics due to its sulphur content, setting it apart from other animal fibres. The fibres of wool are crimped and elastic, growing in clusters. This crimping generates air pockets that provide insulation, while the outer surface features overlapping, serrated scales that enable the fibres to interlock and create felt. For thousands of years, wool has been utilized as a textile because of these distinctive attributes.
Properties of Wool Fiber: The properties of wool fibre include the following:
1. Composition of amino acids: Wool fibres consist of amino acids that form the protein keratin.
2. Absorbency: Wool exhibits high absorbency, which allows it to effectively take in moisture.
3. Moisture retention: Wool can hold a considerable amount of moisture in relation to its weight.
4. Thermal insulation: Wool fibres offer superior warmth compared to many other fibres due to their crimp and structure.
5. Chemical resistance: Wool fibres show limited resistance to alkalis (such as strong soaps or detergents) but are resistant to acids.

Hyperthermia is a condition in which an animal’s body temperature rises above the normal range, often due to excessive environmental heat or a failure in the body’s thermoregulation mechanisms. Unlike fever, where the body actively increases its temperature in response to infection, hyperthermia results from external or internal factors that overwhelm the body’s ability to dissipate heat. This condition is life-threatening and requires prompt recognition and treatment to prevent severe organ damage or death.
The normal body temperature of animals varies across species. For example, dogs and cats typically maintain a body temperature of 101°F to 102.5°F, while livestock like horses and cattle have average temperatures of around 99°F to 101.5°F. Hyperthermia occurs when the body temperature exceeds these ranges, potentially leading to heat exhaustion or heatstroke.
Types of hyperthermia
1. Heat stress/ heat exhaustion: A mild to moderate rise in temperature, accompanied by symptoms like panting, lethargy, or drooling.
2. Heatstroke: A severe and potentially fatal rise in body temperature that causes multi-organ dysfunction or failure.
Causes of hyperthermia
Hyperthermia in animals can occur due to various factors:
1. Environmental heat: Prolonged exposure of animals to high temperatures especially in humid conditions where evaporative cooling (panting or sweating) is less effective. Being left in hot cars or confined
spaces without adequate ventilation.
2. Physical overexertion: Excessive exercise or work, particularly in hot weather, can lead to hyperthermia. Breeds with thick coats or brachycephalic (flat-faced) animals like Bulldogs and Persian cats are
especially prone due to reduced cooling efficiency.

Both possess a pronounced thyme-like odor and flavor. And, both are employed in culinary preparations. The oil of the two plants is closely related in chemical composition. The oil can be obtained by steam distillation of the herb. The dried leaves and flowering tops derived from S.hortensis constitute winter Savory of commerce. The best quality of savory comprises of dried leaves only. S.hortensis constitutes summer Savory. Savory is an erect pubescent annual herb, 20-30 cm in height with pinkish branches, fund in Kashmir State of India. Leaves are oblong – linear or lanceolate with deep-pitted glands on both sides. Flowers are small auxiliary cymes. It grows in Southern France, Germany, Spain, and other parts of Europe, also in England, Canada and the USA. The dried leaves are brownish-green in color, up to 10 mm in length. The odor is strong, warm and highly aromatic; the taste is somewhat sharp and camphoraceous. It is marketed both in whole and ground form. Satureia hortensis Linn., the summer Savory or Garden type, is largely cultivated, although it also grows wild, to some extent. An annual, it is less developed than Satureia montana. Its stalks are herbaceous, covered with soft and linear leaves. The branches frequently are reddish in color. Flowers of the Garden Sage are whitish, dotted with red, growing in a bouquet from the summit of the branches. Satureia montana Linn., the winter Savory, as the French call it “Poivre Diane” grows wild on sunny and calcareous and hill-side of Southern France, especially in the Alpes-Maritimes. It is a hardy, shrub-like perennial, attaining a height of 8-14 inches with small, yellowish or slightly purple leaves, growing

This chapter introduces the recovery and productive utilization of materials generated throughout the wool value chain. It examines wool grease and lanolin, suint salts, noil, short fibre, low-grade wool, waste wool and pelts. Particular attention is given to converting keratin-rich wool waste into biomedical materials, cosmetics, fertilizers, soil conditioners, filtration materials, bioplastics and composites. Insulation, horticultural applications and oil-spill sorbents are also discussed within a circular-economy framework that aims to minimize waste and increase resource efficiency.

The mass spectrometry (MS) is not very well suited to the analysis of mixtures of similar substances because of the multiplicity of fragment ions. The gas chromatography (GC), of course,  has no ability to identify compounds on its own. The GC/MS can easily overcome these defects and can identify the components (fractionated by GC). The combined instrument of GC/MS is an unexcelled instrument that can identify the compounds after their  fractionation.

The GC-MS is composed of two major building blocks: the gas chromatograph and the mass spectrometer. The gas chromatograph utilizes a capillary column which depends on the column’s dimensions as well as the stationary phase properties. The difference in the chemical properties between different molecules in a mixture and their relative affinity for the stationary phase of the column will promote separation of the molecules as the sample travels the length of the column. The molecules are retained by the column and then elute (come off) from the column at different times and this allows the mass spectrometer downstream to capture, ionize, accelerate, deflect, and detect the ionized molecules separately.

Focused assessment with sonography for trauma (abdominal and thoracic) refers to the limited ultrasound examination with the main focus on quick identification of the presence of free fluid within peritoneal, pleural and pericardial spaces in trauma cases in intensive care units. Despite limitations, findings of FAST are helpful in stabilizing the emergency patients.

Crossandra (Crossandra undulaefolia) is one of the important commercially grown flower crop in Tamil Nadu. In recent years there is a marked decline in the cultivation of this crop in Madurai, Dindigul, Coimbatore, Salem, Thiruvannamalai and Tiruchirappalli districts. The common problem with the crop is death of plants in patches during the second and third year. This is due to the nematode-fungal complex disease in the crop.

Lac and other non-timber forest products (NTFPs) provide vital sustenance, employment, and financial revenue to producers and collectors as well as serving a raw material for a range of businesses. They are also important for ecological balance and long-term growth. Weather and price fluctuations have a significant impact on the production of such natural items. Food, fodder, and medication are all ingested straight from these plants. The Indian subcontinent is a significant centre of animal and plant biodiversity. In tropical climates, a variety of forest products play an important role in social and economic life. Wood and Non-Wood Forest Pro

Introduction

One of the most important concerns confronting both developed and developing nations in this age of rapid industrialization is how to deal with the ever-increasing volume of solid waste. One aspect of the environmental crisis that occurs alongside the development of the global economy is the rapid increase in waste volume (Zibres et al., 2011). The threat that organic waste poses to both the natural world and people’s health in today’s modern society makes it a primary topic of investigation in the modern community. The annual production of agricultural waste across the globe is greater than hundreds of megatons, and a significant portion of this waste is either improperly disposed of or burned directly, which contributes further to the acceleration of both global warming and air pollution (Zhang et al., 2016).

The compost that is produced through the biological process of composting can be used as an organic fertilizer in agriculture, vegetable gardens, and other types of gardens. Composting is a biological process that acts on the transformation of the organic matter that is present in the residues into material that is humidified (Antunes et al., 2021). In addition to having low production costs, this method is also environmentally friendly, making it a viable option for the long-term processing of this waste (Lopez-Gonzalez et al., 2015). Composting processes that are mediated by invertebrates from the soil fauna, such as vermicomposting and milli-composting, are proposed along with a variety of mixtures, practices, and management to improve the efficiency of composting as well as the quality of the compost produced. Traditional composting relies heavily on the activity of microorganisms. Vermicomposting and milli-composting are two examples of composting processes that use invertebrates from the soil fauna. Milli-composting is a relatively unknown biotechnology that uses diplopods, more commonly known as millipedes, to increase the biotransformation of vegetable wastes into stable organic matter. It not only aids in climate change mitigation but also aids in carbon sequestration, so milli-composting can be used as an alternative to modern composting as it is crucial for preventing pollution and promoting lush plant life.

Introduction

In Puducherry, the first KVK was founded in 1974. In the newly constructed districts and several larger districts, 106 additional KVKs will be established, bringing the total number of KVKs to 645. KVKs are approved for use by Agricultural Universities, ICAR Institutes, associated Government Departments, and Non-Governmental Organizations (NGOs) engaged in agriculture. The KVK initiative is fully funded by the Government of India. KVK, which is a crucial component of NARS, aims to evaluate location-specific technology modules in agricultural and related companies through technology assessment, refinement, and demonstrations. As a knowledge and resource centre for agricultural technology, KVKs have supported public, private, and non-profit sector efforts aimed at enhancing the district’s agricultural economy(1).

The KVK’s mandate has changed from vocational training to technology assessment and demonstration for its application and capacity building in a district in preparation for its growing contribution to NARES in India. Though technologies were developed at ICAR Research Centres or State Agricultural Universities, KVK carried out location-specific technology assessments, micro location refinements on farms with genuine problems, and final technology certification for widespread adoption by farmers(2).

Spectrophotometry measures how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through the sample solution. Chemical compounds normally absorb or transmit light over a certain range of wavelength. Hence spectrophotometry is used to measure the amount of a known chemical substance. It is one of the most useful methods of quantitative analysis in the laboratory and is widely used.

A  colorimeter or spectrophotometer is an instrument that measures the amount of photons (the intensity of light) absorbed after it passes through the sample solution. With the spectrophotometer, the amount of a known chemical substance (concentrations) can also be determined by measuring the intensity of light detected. Depending on the range of wavelength of light source, it can be classified into two different types, namely,1) UV-visible spectrophotometer which uses light over the ultraviolet range (185-400nm) and visible range (400-700nm) of electromagnetic radiation spectrum and 2) IR spectrophotometer which  uses light over the infrared range (700-15000nm) of electromagnetic radiation spectrum.

Giant granadilla, Passiflora quadrangularis L. (syn. P. macrocarpa M.T. Mast.) is the largest fruit in the genus Passiflora. With more than 450 species, Passiflora is the most important genus of family Passifloraceae. It is further divided into 24 subgenera (Killip, 1938). Most of the species producing an edible fruit belong to subgenera Passiflora and Tacsonia. Many species have ornamental interest because of unique and spectacular flowers, or are used for their sedative, antispasmodic, antibacterial, and insect-resistant properties.

Origin and history: Guava (Amrud) is one of the most common fruits in India.  It is a very hardy sub-tropical plant and prolific bearer. In India, it is commonly called as “poor man’s apple” widely naturalized in the country. Allahabad has the reputation of growing the best guava in the country as well as in the world. Area wise guava comes under 4th position after Mango, Banana, Citrus, in India. Uttar Pradesh has the largest area fallowed by Bihar, Madhya Pradesh, Maharashtra, Gujarat, and West Bengal, however it is generally grown all over India and also grown in South Asia that is Srilanka, Myanmar and tropical and subtropical country. Beside Psidium guajava some other important species which are commercially grown for rootstock purpose that is :

Respiration rate, irrespective of plant parts (viz. leaves, fruits or seeds), is considered to be an important parameter in plant physiological studies. Respiratory gas exchange is just reverse or opposite to that of photosynthesis and as the later is an energy building phenomenon where ATP is stored in the photosynthates produced; respiration involves breakdown of photosynthates for release of energy to be utilized for the performance of other activities of life. Respiration plays an important role during seed germination. A germinating seed requires a lot of energy which is derived from the breakdown of different types of food reserved in the cotyledons. On the basis of respiration a climacteric fruit can well be distinguished from a non climacteric one; as the former reveals a characteristic ‘Climacteric Burst’ in respiration, which is completely lacking in the later.

There are a few instruments used for the measurement of respiration in plants viz.:

ABSTRACT

The Cretaceous formation of Ariyalur area is well known for its lithological and faunal variation. It contains rich assemblages of fossils as well as the occurrence of economic deposits of limestone, gypsum, phosphatic nodules and clays. Representative Uttatur clay samples have been collected and analysed for physical and chemical properties. The physical properties such as fired colour, plasticity, fusing temperature, slaging nature, shrinkage test, bulk density, liquid limit, and plastic limit and Atterberg number etc. of uttatur clays have been determined. The chemical properties of the clays show low in silica and alumina and high iron and lime which make them suitable for low duty refractories and stoneware works.

Human societies over the ages have depleted natural resources in different ways and degraded their local environments. Indiscriminate cutting down of trees and accelerating the construction works lead to global warming and climate change. Climate scientists believe that human-induced deforestation is responsible for 18-25% of climate change. Accumulation of greenhouse gases in the lower atmosphere is the main cause of global climate change. The concentration of these gases in the earth’s atmosphere is increasing, mainly due to deforestation and the combustion of fossil fuels which release carbon dioxide.

The earth receives heat energy constantly from the sun through radiation. Some of the heat is absorbed and some is reflected. Carbon dioxide works like an invisible blanket that wraps around the earth and traps the heat inside, similar to the function of a greenhouse. A greenhouse is a structure that is used in colder climates to grow plants. Even when outside temperatures drop below freezing point, greenhouses are still warm enough inside to grow plants. Greenhouses are made of glass, which allows solar radiation to enter. The heat is trapped inside the greenhouse, allowing plants to grow all the year round. Increasing concentrations of carbon dioxide in the earth’s atmosphere insulate it like a greenhouse, leading to a gradual warming of the earth’s atmosphere. Carbon dioxide is the major greenhouse gas, but there are others as well, including methane and nitrous oxide.

Mitigation means addressing the causes of climate change, while adaptation attempts to tackle its effects. The Intergovernmental Panel on Climate Change defines mitigation as an anthropogenic intervention to reduce the sources or enhance the sinks of greenhouse gases and adaptation as the adjustment in natural or human systems to a new or changing environment (IPCC, 2007).

Pesticide Authorities

In India, the central pesticide board and registration committee oversee the import, production, sale, transportation, distribution, and use of insecticides. Pesticides in India are regulated by the following two government organisations Central Insecticides Board and Registration Committee CIBRC and Food Safety and Standards Authority of India (FSSAI ).

Central Insecticide Board (CIB)

• The Central Insecticides Board advises the central and state governments on technical issues arising from the administration of this act, as well as carrying out the other tasks given to it by or under this act.

Introduction

Agriculture is a major sector in Indian economy. It is one of the biggest production sector contributing more than 20 percent of GDP for India’s economy. Its is the largest provider of employment in Rural India. Over 70 percent household depends on agriculture. Its provides raw materials to industries and market for industrial product(Kekane, 2013).

Therefore, agriculture is a main sector for the planning of social and economic development of the country. Rapid growth of agriculture is essential not only to achieve self reliance at national level but also for household food security and to bring about equity in distribution of income and wealth resulting in rapid reduction in poverty line (Shrivastava et al. 2010). Agriculture is considered as the biggest unorganized sector where large numbers of women are working for their livelihood. The farm women comprise a quarter of the word’spopulation . Women also make up 41 percent of the word’s agriculture labour force, a ratio which rises to 49 percent for low income countries (ILO,2018).

Women play an important role towards the growth of the agricultural sector and its other associated areas. They perform multifarious tasks in agriculture and its allied fields. They are playing an important role in most of the farm operation like land preparation, seed treatment, sowing, planting, weeding, intercultural operation, irrigation of crop, application of manures and fertilizers, protection of crop, harvesting, threshing, storage etc. There is hardly any activity in agricultural production, except ploughing in which women are not actively involved. In some of the farm activities like processing and storage, women are dominant so strongly those men workers numerically insignificant (Patil and Babus 2018).Naidu et al. (2020) found that 63 percent of women are engaged in sowing of seeds and transplanting followed by in harvesting operation (61%), wedding (59%), winnowing (27%), manure and fertilizer application (25%) on regular basis.

Introduction

Crops diseases are caused by bacteria, virus, fungi and phytoplasmas. The detection of pathogenic bacteria and viruses in plants, planting material, vectors or natural reservoirs is essential to ensure safe and sustainable agriculture. The molecular based techniques, have evolved significantly during recent past that  allows the rapid and reliable detection of pathogens. The detection and diagnosis of plant pathogens is essential to take control measures and subsequently for eradication of the disease that causes.  Molecular detection is largely based on PCR or RT-PCR amplification following purification of nucleic acids from the samples, with the extraction of the target DNA.
