Flowers symbolize beauty, purity, peace and love. These are intricately associated with social beliefs and no social function is complete without the use of flowers; especially in a country like India, where it is a popular saying that flowers are associated with man from birth till death. Floriculture can be defined as a specialized branch of horticulture which deals not only with the cultivation of flowers, foliage, climbers, trees, shrubs, cacti, succulents, etc., but also with their marketing and production of value-added products from them.

Floriculture is increasingly regarded as a viable diversification from the traditional field crops due to higher returns per unit area and increasing habit of “saying it with flowers”. Flowers play a cardinal role in human behaviour and culture, bringing tranquility and peace of mind. From a symbol of love, flowers have transformed into an industry, generating both income as well as employment. India is blessed with a diversity of agroclimatic conditions prevailing in different regions of the country ensuring production of almost all the ornamental crops through out the year. Floriculture in India is a dynamic and expanding industry recording impressive annual growth rate.

The floriculture industry comprises of:

1. The florist trade traditional and contemporary cut flowers and cut foliage, both fresh and dried and value-added products like bouquets, floral baskets, flower arrangements and garlands.
2. The plant nursery for propagation and supply of plant material including tissue culture plants, seeds, bulbs, corms and other propagated material.
3. Plant rental service for supply of house plants on annual rent for a specific period.
4. Flower perfume and gulkand.

As a result of political changes in India, many entrepreneurs are changing to floricultural activities, which have become a high priority for the Indian government. Due to availability of sufficient winter and summer sunshine, high temperature, good soil fertility, good water quality, different climatic zones for different type of products and low labour and investment costs, India has great potential for floriculture. In the flower industry, significant changes are occurring in the competitive relationships worldwide. European integration, democratization in eastern Europe and the liberalization of world trade in the context of the GATT negotiations will have consequences on international trade. A number of traditional markets are displaying signs of saturation while, on the other hand, new countries are trying to get their place on the market. At the same time, we see new developing markets and in some parts of the world (USA, Japan) it is expected that per capita consumption will go up. Enormous genetic diversity, versatile human resources and varied agro-climate offers India unique scope for diversification not explored yet fully.

Seed processing is specialized activity and also a tool to improve seed quality further to an acceptable standard. Seed quality parameters like germination, vigour or genetic purity can be improved using processing. Say a seed lot having a minimum standard of 90% germination, but the competition in the market offering seed quality 92 or 95 % then to meet the market demand we can process the seed lots using re-milling or re-conditioning techniques. Also sometimes simple techniques like liquid density separation which uses specific density of the seed to separate good seed from inferior quality can be considered. Various case studies on processing to improve seed quality are given here.

Soil temperature is an important environmental parameter for plant growth and development. It has direct effects on microbial growth and development, organic matter decay, seed germination, root development, and water and nutrient absorption by roots. In general, the higher the temperature the faster these processes occur. Variation in soil temperature is much more pronounced because of varying characteristics and composition of soil.

The soil gains heat by absorption of solar radiation and longwave counter radiation from the atmosphere, downward transfer of sensible heat and horizontal transfer of heat from the surroundings. On the other hand, soil loses heat by longwave radiation to the atmosphere, upward transfer of sensible heat to air when the soil surface is hotter than air and with evaporation and horizontal transfer of heat from the column to surroundings.

Introduction

Audiotex is a voice response application that allows users to enter and retrieve information over telephone. Example Interactive Voice Response System (IVRS). Audiotex is a generic name for interactive voice response equipment and service. Audiotex connected with a telephone is like a data processor connected to a data terminal. They are passive service which provides through appropriate access by standardised procedure for the user of Audiotex service to communicate with database via telecom network (i.e.) a subscriber can retrieve the information at any time by interacting with the audio service equipment by using the existing telephone line.

Audiotex is essentially a content provider. It enables the subscribers to record their message in a computer memory area called a “Mail Box”. The recorded message can be retrieved by the recipient by dialling a telephone number. Audiotex service is a telecommunication system which enables a caller, by dialling a designated telephone numbering beginning with ‘1800’ to receive a recorded announcement or to interact with a programme whereby he/she may communicate by means of a dual tone multi frequency telephone key pad, a touch tone telephone or other similar device with a value added network connected to the public switched telephone system for purposes of sending or receiving information. However, there are differing views across the world on what constitutes “Audiotex service”. European Telecommunications Standards Institute in its ETSI technical report 131 (June 1994) on “Terminal Equipment(TE); An investigation into the need for standardization in the area of stored voice services” has commented that “ It can be seen that there are many differing views as to what constitutes an Audiotex service and, in formal usage (e.g. in lectures or articles on the subject), a distinction is always drawn between voice messaging and the other services (information, consultation, transaction, etc.). It is thus misleading to use the word Audiotex without a previous definition. Therefore, in many countries the term “stored voice service” is used to describe Audiotex and each separate application and service is distinguished by a more precise definition.

The demand for nutrients is rising, along with the population, which is rapidly expanding. The sustainability of life on earth now places a high focus on protecting the sources of sustenance. In this regard, aquaculture has a crucial role to play. The regulated raising of fish and other breeds in a particular environment is known as aquaculture. The natural resources and other elements required for sustainable development can be preserved using this method. The promotion of the value of nutrients and the expansion of employment prospects in the future are both made possible by aquaculture. Biofloc fish farming, which has set trends in fish farming all over India, facilitates recycling and reusing of the nutrients in the culture medium by filtering the unwanted substances and metabolites and converting them into nutrients, which benefits the zero exchange of water.

Types of Traditional and Modern Farming Systems
India, with its diverse agro-climatic conditions, has witnessed the coexistence of both traditional and modern farming systems. These systems reflect the evolution of agricultural practices—from indigenous knowledge and
subsistence farming to technology-driven, market-oriented approaches. A. Traditional Farming Systems Traditional farming systems are based on indigenous knowledge, ecological balance, and subsistence needs. These systems are often practiced by tribal, marginal, and small-scale farmers and are well-adapted to local environments.
Types of Traditional Farming Systems
1. Subsistence Farming
Subsistence farming is a traditional farming system in which a farmer grows crops and/or rears livestock mainly to meet the needs of their own family, with little or no surplus for sale in the market. It is generally practiced on small landholdings, using simple tools, indigenous seeds, and family labor.
• Focus: Meeting the food needs of the family.
• Crops: Millets, pulses, vegetables.
• Tools: Manual or animal-drawn implements.

ABSTRACT

India is the second largest producer of vegetables in the world after China with an annual production of 162.19 million tonnes from an area of 9.2 m ha. The requirement of vegetables in the country has increased a lot to meet the nutritional requirement of an estimated 1200 million population expected by 2020-21. Although the productivity levels of vegetables have increased manifold, it would not be sufficient to feed the ever increasing population. Production per unit area of land, time and inputs can be increased by improving efficiency of the rate and extent to which solar energy is harvested for conversion to economic produce. In multiple cropping systems, the possibility of more efficient use of resources like sunlight, nutrient and water per unit area is higher leading to higher production stability. It can be very much successful in high imput requiring crops like vegetables. Intensive cropping involving multi-tiered vegetable crops like pointed gourd + elephant foot yam + cowpea grown on the single piece of land at the same time can generate profits up to Rs 1,30,000 per acre. India ranks first in the youth population. If the energy of these dynamic youth is properly utilized in the field of better agricultural practices, especially vegetable cultivation, it will help improve the national productivity of vegetable crops and generate employment as a whole. Thus, intercropping involving multi-storied/ multi-tier cropping system can serve as well-established practice for sustained supply of vegetables throughout the year through which rural youth can generate high income for sustainable livelihoods and increased per capita income.

Mahua (Bassia latifolia Roxb.), is a deciduous, hard woody multipurpose tree species (Venkatesh,1998). It is very hardy and thrives well on rocky, gravelly red soils and also on saline and sodic soils. It can grow even in pockets of soil between crevices of barren rock. Trees are grown on degraded rocky area including salt-affected soils and forests area.  Mahua prefers tropical and sub-tropical climate. It can withstand drought admirably. A characteristic tree of the dry region is found in north and central India.  It commonly grows in eastern Uttar Pradesh, Madhya Pradesh, Maharashtra, Bihar, Odisha, Andhra Pradesh and Gujarat.  In Rajasthan, it is also found growing on the wastelands particularly in southern part of the state.  The tree is very well known to rural folk since ages in India.

Over the past few decades, the fields of science and engineering have been seeking to develop new and improved types of energy technologies that havethe capability of improvinglifeall over the world. In order to make the next leap forward from the current generation of technology, scientists and engineers have been developing Energy Applications of Nanotechnology. Nanotechnology, a new field in science, is any technology that contains components smaller than 100 nanometers. For scale, a single virus particle is about 100 nanometers in width.

An important subfield of nanotechnology related to energy is nanofabrication. Nanofabrication is the process of designing and creating devices on the nanoscale. Creating devices smaller than 100 nanometers opens many doors for the development of new ways to capture, store, and transfer energy. The inherent level of control that nanofabrication could give scientists and engineers would be critical in providing the capability of solving many of the problems that the world is facing today related to the current generation of energy technologies.

People in the fields of science and engineering have already begun developing ways of utilizing nanotechnology for the development of consumer products. Benefits already observed from the design of these products are an increased efficiency of lighting and heating, increased electrical storage capacity, and a decrease in the amount of pollution from the use of energy. Benefits such as these make the investment of capital in the research and development of nanotechnology a top priority.

This is a branch of veterinary science that deals with the biology of animal when they are in good health condition, disease status and also deals with the selection of the laboratory animal, important care to be taken and also the usage of these laboratory animals in experiment and also for other research activities.

IMPORTANCE / SCOPE FOR STUDY

Veterinarian with special training/ advanced training in laboratory animal medicine and management are required by medical school, pharmaceutical industries, private and government organization, hospitals, research institutes.

This field of veterinary science has become highly dynamic and it provides good opportunities to satisfy academic professional career.

Usage of these laboratory animals goes back to 2^nd Century. However, the systematic and systemic usage came into existence a century back when research workers started working on polio vaccine. Since then, a debate is going on between scientists of different organizations regarding the usage of laboratory animals.

Seed certification

It is a legally sanctioned system for quality control and seed multiplication and production. It involves field inspection, pre and post control tests and seed quality tests. As per Indian Seed Act seed certification is voluntary and it is not compulsory. The seed that is sold in the market is of two types certified seed or truthfully labelled seed. Whereas truthfully labelled seed is one which is being produced and marketed by the producing company by maintaining the labelling standards.

Atmospheric pressure is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of earth. The gas molecules of the atmosphere are pulled towards the earth by the force of gravity and hence exert a force on earth surface. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Atmospheric pressure influences other weather elements in a significant way. Small changes in air pressure may not be felt, but they are important for bringing a change in weather. Atmospheric pressure can be calculated as the summed weight of all gas molecules between a horizontal plane and top of the atmosphere and divided by the area of the plane. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location.

Measurement of atmospheric pressure

The standard unit of pressure in the SI system is the Pascal which is the name given to one Newton per square metre (N/m²). For meteorological purposes, standard sea-level pressure is 101325 pascal (Pa). To simplify this large number, the millibar unit (mb) has been adopted, which is equal to 100 pascals. Units like kiloPascal (kPa) or hectoPascal (hPa) are also used to measure pressure. 1 kiloPascal is equal to 10 millibars and 1 hPa is 1 millibar. The standard sea-level pressure is represented as 1013.2 mb or hPa.

Introduction

The Kisan Call Centre is an ICT initiative launched by the Department of Agri- culture and Cooperation, Ministry of Agriculture on January 21, 2004 to instantly respond to farmer’s queries in their local language. Farmers from any part of the country can contact KCC simply like common public do to contact the customer care of their preferred network for queries. If it is a BSNL connection KCC can be contacted by just dialling 1551 toll free number. If it is other network, then farmers can dial “1800-180-1551” and get their query solved. In Tamil Nadu, until 2014, it was Cartel India Limited which acted as Level-III centre for Kisan Call Centre in Tamil Nadu. From May 2014 onwards, the administration of Kisan Call Centre was taken over by Indian Farmer Fertilizer Company (IFFCO) and working since then in the name of IFFCO Kisan.

In today’s condition, the policy makers feel it as a real challenge to bridge the com- munication gap that prevails between two farmers, between two villages, between two regions and perhaps between two countries. The only way to bridge this gap is through some ICT initiatives. Recent studies have shown impressive growth of telecommunication network for effective information utilization and delivery of knowledge and information in the country. In Kenya, the helpline service was start- ed on a pilot basis by GSMA Foundation, Inc., which was funded by Rockefeller Foundation. The technology was named Kenya Farmer’s Helpline. It was mainly started to bring a change in the economic, social and environmental development in the country. The helpline received very good support from the local farmers and till 2010, the helpline solved queries of over 30,000 farmers. During the same period, India solved queried of over one lakh farmers. Now, the number would be much more than what we expect.

Wood apple (Feronialimonia) commonly known as Bael in various Indian sub-continent languages is the most under-utilised fruit despite of its aromatic flavor, high nutritional components and important medicinal values. Reason may be due to challenge in harnessing the pulp from the fruit. It is considered under seasonal fruit but it has long duration of shelf-life as compared to other fruits.The physic-chemical characteristics revealed that it has high shell weight of 55.67% as compared to pulp weight of 43.77% (Devi et al. 2018).

Introduction

Cherries occupy an important position among temperate fruits all over the world. Cultivated cherries are divided into two main groups, i.e., sweet cherries (Prunus avium) and sour cherries (P. cerasus). Cherries are rich in protein, sugar, potassium, calcium, iron and zinc. Sweet cherries are believed to have originated in an area between the Black and Caspian Seas in Southern Europe. The earliest records indicate that it was first domesticated in Greece around 300 BC. It spread to Italy from Greece where it was established as a fruit crop by 37 BC. Early setter’s brought seeds to North America and parts of South America. In India, it was introduced by British setter’s in Kashmir, Kullu and Shimla hills during the pre-independence era. World leading breeding of cherry: John Innes Horticultural Institution, Merton. A putative ancestor of cultivated sweet cherries: Anthocynins (antioxidants) are the red pigment found in cherries.

The Indian economy, which meets its own dairy demands, has reached a turning point with its bovine breeding initiatives. The viability of this enterprise, however, depends largely on completing as many successful artificial insemination cycles at a cattle farm. Estrus behaviour observation is used to determine when artificial insemination should take place. But since not all cattle exhibit substantial estrus symptoms, insemination results are not always reliable. An estrus detecting instrument known as an Electronic Nose (eNose) is created to address these issues.

It is clear that Odisha has significant potential for aquaculture due to its vast brackish water resources. However, as the aquaculture industry grows, it is important for farmers to be knowledgeable about the inputs and techniques they use to ensure the sustainability of the industry. A total of 2.98 lakh ha of estuaries, 0.081 lakh ha of backwater, 0.80 lakh ha of Chilika Lake, and 0.32 lakh ha of cultivable brackish water area make up the 4.18 lakh ha potential brackish water area for fish and shrimp production. Additionally, proper disease diagnosis and management are crucial for reducing the risk of disease outbreaks and ensuring the health of the aquatic animals being farmed. With appropriate training and support from organisations such as the Aqua One Centre, farmers can improve their practices and increase their yields, while also contributing to the economic growth of the region.

Scientific name: Vetiveria zizanioides L.
Family: Poaceae
Vetiver, scientifically known as Vetiveria zizanioides L., is a tropical grass species belonging to the Poaceae family. Native to India and Southeast Asia, Vetiver is a perennial grass that grows up to 2 meters in height, with long, thin leaves and a deep, fibrous root system. Vetiver is highly valued for its essential oil, which is extracted from its roots and used in perfumery, aromatherapy, and traditional medicine. The plant is also known for its soil-stabilizing properties, making it an effective tool for erosion control and land conservation.
Origin and distribution
Vetiver is native to the tropical regions of Asia, specifically India, Pakistan, Bangladesh, Sri Lanka, and Malaysia. It is cultivated and produced in many parts of the world, including Tropical Asia, Africa, Australia, Haiti, Indonesia, Guatemala, India, China, and Brazil. Vetiver is also grown in several other countries, such as the Philippines, Japan, Angola, Dominican Republic, Argentina, and Jamaica. The global production of Vetiver is estimated to be around 250 tons per annum. In India, Vetiver grows wild in various states, including Punjab, Uttar Pradesh, and Assam.
