Cotton

Cotton is one of the most important fiber and cash crop of India and play a key role in economic and social affairs of the world. Cotton is referred to as “King of Fibres” and also known as “White Gold”. India is largest produces of accounting for 22% cotton in the world. Nearly 65 per cent of the cotton crop is grown under rainfed conditions. Cotton production, processing and trade provides livelihood to several millions of people.

Scientific Name : Gossypium hirsutum

Family : Malvaceae

Origin: Cotton has been used as a fabric in India from time immemorial. It has been cultivated in the Indus Valley for more than 5000 years before. The excavations of Mohen-jo-daro indicates a high degree of art in spinning and weaving with cotton at that time. It finds mention in the Rigveda, the oldest scripture of the Hindus. Manu also refers to it in his Dharma Shasta. India appears to have been the centre of an important cotton industry as early as 1500 B.C.

Benign/malignant tumor may arise from fibrous tissue. Fibroma mostly occurs in the dermis or subcutis of limbs and head.

The tumour is most commonly seen in adult and aged dogs. It occurs anywhere on the body surface. It is due to trauma, chronic inflammation, vaccination, genetic predisposition etc.

Fidelity is said to exist in a communication situation when there is no distortion of the message from the time it leaves the source until it is received. The most effective communication occurs when the message transmitted and the message received are identical i.e., when complete fidelity is there. Some communication theorists believe that complete fidelity can never be achieved that no message is ever received exactly as it was intended by the source. This seems likely, since the source and receiver always have different frames of reference. It is clear, however, that the fidelity of any communication can be vastly improved by several methods.

Methods to Improve Fidelity

a) Use several channels of communication

To say the same thing, thus providing a duplication of information. Multiplying the channels used will make communication redundant. A smile, a node of the head, a firm hand shake or embrace and the greeting "Hi! How are you?" often convey the same meaning – meaning that would be conveyed through a single channel or redundantly through more than one.

b) Control the speed of communication

Information is processed by different individuals at different speeds. The rate varies for each situation and for each of the individuals in various situations. In talking casually to a few friends, we might speak very quickly where as in talking to a large group of strangers, we might want to talk more slowly because of the increased possibility for misunderstanding, the intrusion of noise. Whether we should speed up, slow down, or become more succinct (briefly and clearly explained) has to be a function of the feedback we gain. There is no specific rate that is ideal for all – except that rate at which a high degree of fidelity can be attained. It is the rate at which the amount of noise affecting the communication can be minimized. Sender and receiver should be aware of how communication works and interested in achieving the greatest f idelity possible

All infectious agents, toxins, and nutritional imbalances have an impact on the performance of the farm and consequently on the local poultry industry. Additionally, poultry can be infected with common diseases like endoparasites, ectoparasites, infectious bronchitis, Marek’s disease, fowl cholera, salmonellosis, infectious coryza, fowl pox, avian encephalomyelitis, etc.

Controlling infectious diseases is vital for poultry health and diagnostic methods are an indispensable feature to resolve disease etiologies and the impact of infectious agents on the host. Although the basic principles of disease diagnostics have not changed, the spectrum of poultry diseases constantly expanded, with the identification of new pathogens and improved knowledge on epidemiology and disease pathogenesis. In parallel, new technologies have been devised to identify and characterize infectious agents, but classical methods remain crucial, especially the isolation of pathogens and their further characterization in functional assays and studies.

In poultry medicine, the diagnostic process originally shifted from the traditional veterinarian approach centered on individual animals to the health assessment of entire flocks. Flocks are commonly classified as “healthy” if they perform according to their genetic potential and are considered free from clinical disease. On-farm, diagnostic activities comprise routine sampling and investigations in line with health control programs; nationally and/or internationally adopted control programs for certain Mycoplasma and Salmonella species represent examples of paramount importance. Samples may be investigated immediately on site (e.g., rapid antigen test for avian influenza) or sent for further processing to a laboratory (e.g., ELISA and PCR). Field veterinarians further implement diagnostic surveillance in order to provide epidemiological data for flock management purposes. The periodical collection of samples (e.g., feces, serum samples, and swabs from mucosal surfaces) is primarily used to confirm the infection (free) status of a flock or to monitor vaccine response. Altogether, generated data facilitate objective judgment and decision making in order to optimize flock health and production.

Entomopathogenic nematodes (EPN) in the family Steinernematidae and Heterorhabditidae have enormous potential to control insect pests of economic importance. Since, chemical pesticides pose environmental hazards, these nematodes have received considerable attention as potential bio-insecticides because of their wide host spectrum, active host seeking, killing the host within 48 h, easy mass production, storage and application and are environmentally safe. One of the important criteria for a successful biocontrol agent is formulation of nematodes into a stable product, which has played a significant role in commercialization of these biological control agents. Apart from formulation field application and desired control of insect pests decides the success of EPN.

Formulation of Entomopathogenic Nematodes

EPNs have been known since 1929 but they became commercially available only during 1990s.The first attempts at formulating EPN were initiated in 1979 but the shelf life was very limited (one month). Infective juveniles carried on moist substrates such as sponge, vermiculite and peat require continuous refrigeration to maintain their viability. While formulating nematodes, two things are necessary, a long shelf-life and easy application method. The simplest method is impregnating a moist substrate (such as sponge, peat, vermiculite, etc.) with nematodes. The sponge needs to be squeezed in water before application, to release the nematodes, whereas nematodes from other carriers could be applied directly to the soil. However, these formulations are labour-intensive, require continuous refrigeration and lack economy of scale and therefore can be used on small scale only.

Although the infective juveniles of entomopathogenic nematodes can be stored for several months in water in refrigerated bubbled tank, high cost and difficulties of maintaining quality preclude the deployment of this method. Therefore, nematodes are usually formulated into solid or semi-liquid substrates soon after they are produced.

This practical assignment is dealt with collection, collation and maintenance of field and lab related information in a single compendium or diary.

PURPOSE

To make the students acquainted with the field diary and lab record

THEORETICAL ORIENTATION

Field Diary

There are two kinds of field notes

Definition – Components to be included – Parts of field diary – Field diary in social sciences.

The field diary is the basic document which contains all the data collected. Facts and interpretations are to be written separately and conversations to be noted in the vernacular languages. Two kinds of field notes are to be observed a) Taking notes on the spot b) Writing detailed diary.

Daily field diary

It is instructed to write the field diary everyday in which a) Detailed notes of observations b) Field notes on discussion and conversations c) Details of Interpersonal communication, gossips, fold history‘s similar events d) Specific details of special events Specific reference about the main field of study for instance, the details about the process of message diffusion, various kinds of channels of communication were described in detail.

Field diary for research process documentation

The most useful tool for a process documenter is a field diary. The documenter uses a field diary to record his or her observations and thoughts in an orderly fashion. Recording observations and impressions enables a researcher to pick up clues about how the system is operating. A field diary should help the investigator understand the systems physical and social setting. It should help describe who, what, why, where, when and how. Who refers to the people or system being studied. What concerns the information gathered. Why, where, when and how provide important details about the observation.

There is no special format in writing a field diary but entries should be written daily in chronological order so information is not forgetten or changed because of forgetfulness. The critical concern is that observations are recorded in a diary regularly.

ABSTRACT

Lack of high yielding varieties, variation among progenies through seedling propagation and transmission of viral diseases through sucker propagation together contribute to the decline in productivity of large cardamom (Amomum subulatum Roxb). To increase the productivity of this crop, planting material raised through tissue culture techniques from few selections having higher productivity was considered. From the study, it was revealed that TC plants were superior to conventionally propagated plants due to vigorous growth during juvenile phase, precocity in the yield and higher productivity compared to that of open pollinated seedlings.

Introduction

Fresh fruit journey from the farm to the consumer’s table is an intricate process which needs a lot of attention. The way that the produce is harvested and handled is of supreme importance in relation to its quality shelf life and general market attractiveness. Improper handling practices during these critical stages can bring both quantitative and qualitative loses hence the perishable produce will lose its commercial value and appeal to the consumers (Kader, 2005). No doubt the significance of successful harvesting and post-harvest handling practices is crucial and has an impact on quality features and safety in case of fresh fruits. Poor management can cause physical assault ripening speed and more susceptibility to the growth of micro-organisms which makes the produce unsuitable for consumption or processing.

21.1 Liquid Nitrogen Container/ Cryocan

To store liquid nitrogen a special type of container is used and is known as a LIQUID NITROGEN CONTAI NER OR CRYOCAN. Frozen semen doses are always preserved in liquid nitrogen which is an inert liquid having a boiling point of -1960C and a freezing point of -212°C. Liquid Nitrogen Containers are doubled walled metal (Stainless Steel/Aluminium) vacuum vessels with a very efficient insulation system. Due to highly efficient insulation system the temperature inside the container can remain -196 oC as long as atleast two inches of Liquid Nitrogen is present in the container. It has got an inner chamber which is suspended in outer chamber through neck tube which is a non metal and bad conductor of heat. Walls of the inner chamber are coated with a high quality of insulation material. The space between the inner and outer chamber is also filled with high quality insulation material. Vacuum is created in between inner and outer chamber. Loss of vacuum will lead to the boiling of the liquid nitrogen gas and hence rapid loss of this gas from the inner chamber.

Introduction

For optimum use of harvested rain water in surface reservoir like farm ponds or tankas, small sized solar PV pumping systems with 1 hp AC and DC motor were experimentally tested at research farms of ICAR-Central Arid Zone Research Institute, Jodhpur (Fig. 16.1). Total suction head in both pumps was about 5 m. Among two installed pumps, the system with AC pump consisted of 1400 Wp (200 Wp × 7) whereas the DC pump consisted of PV array of 920 Wp (230Wp × 4). Each PV panel of AC solar pump was connected in series, which was further connected with an inverter to generate AC output of about 220-240 volt and 4-4.2 ampere. In case of DC solar pump, panels are connected in parallel to generate DC output of 40-50 volt and 15-20 ampere.

Plant breeding activities basically involve development of new and superior crop varieties to replace the old ones and this naturally needs comparison of several lines/cultivars for agronomically important traits which are often quantitative in nature. Therefore, lots of environmental influences are there on the mean performance and mere numerical comparison of mean data is not sufficient to draw valid conclusions regarding the superiority of one variety over the other. Great advances have been made during the last about 100 years in the area of experimental designs and analytical procedures to facilitate such comparisons. Most commonly used designs by the plant breeders are included here for better understanding by the students and the breeders and to handle the experimental data on their own when confronted with such issues. Before applying statistical procedures on the experimental designs, it must be well understood that proper use of field plot technique is of great value to have meaningful data for further statistical analysis and use.

Introduction

Agricultural production in India is constrained by number of biotic and abiotic factors. India is a tropical country and has a climate which is conducive for insect pests which are, one of the major constraints in agricultural production, processing and storage. Annual crop losses due to insect pests and diseases in India are estimated to be 18 percent of the agricultural output. Insect pests are widespread in all the agroclimatic zones and large quantities of insecticides are used to control these pests. Indiscriminate use of insecticides, lack of adequate knowledge on proper application techniques and dosages, and frequent use of broad spectrum insecticides are common in India. There is a need to identify suitable alternative methods for the management of insect pests and among them, biological control using viruses, bacteria, fungi and entomopathogenic nematodes is gaining greater attention world over.

Nematode families of Steinernematidae and Heterorhabditidae attracted most attention as they contain the entomopathogenic nematodes (EPN). Entomopathogenic nematodes are obligate parasites of insects that kill their hosts with the aid of bacteria (Xenorhabdus and Photorhabdus) carried in the nematode’s alimentary canal. The lethal obligate insect parasites are ubiquitously distributed without pathogenicity to mammals and beneficial non-target insects, and exempted from registration requirements. Currently there are about 98 valid EPN species belonging to Steinernema (79) and Heterorhabditis (19). Soil surveys conducted in divergent areas of Indian subcontinent have demonstrated high diversity of EPN across seasons, habitats, and geographic regions. There are several target pests in India that can be controlled with entomopathogenic nematodes and several workers have used EPN against cutworms, stem borer, white grubs, etc. under laboratory and field conditions and are compatible with existing IPM programmes.

1. INTRODUCTION

Vegetables differ widely from field crops in their requirements for land preparation and cultural practices because of their differences in their morphologies, growth habit, and socio-economic values. In preparing land for vegetable production, ecological location, mode of cropping, season, crop disposition and the type of vegetables to be grown are taken into consideration.

Clearing: It is often necessary to remove the vegetation cover when a piece of land is to be used for vegetable production. The land clearing methods may involve removing the remains of previous crops and undergrowth, cutting back the woody shrubs and trees and burning them.

Levelling: When the site has been cleared, uneven land may have to be leveled. This facilitates the process of ploughing, harrowing ridging and layout of the site.

Land preparation and layout depend on

Minimum field standards for seed production have been prescribed  for each crop. The major components to be looked into for meeting the field standards are: 
   Preceding crops 
   Isolation distance 
   Number of field inspections 

The minimum proceding crop requirement has been specified to minimize genetic contamination on account of volunteer plants germinating from the left over seeds in the previous season. The disease contamination is also possible from soil borne disease organisms if the previous crop was not certified. The preceding crop requirement would mean that for a prescribed minimum period the same crop or any other contaminating crop should not have been grown on the same field where seed production is to be taken up unless the preceding crop was a seed crop and had met the field/the seed standards.

Many farmer participatory field  experiments were designed and conducted in different states of India having large area under acid soils, with locally available soil ameliorants to study their effect on soil health and crop performance. This work was done during 2000 & 2005 under an ICAR network project on “Soil characterization and resource management of acid soil regions for increasing productivity”. The details of the field locations are presented in table 1.

13.1 Biosafety Research Trials: Scope and Implementation
Introduction
Biosafety research trials serve as a critical phase in the evaluation and regulation of genetically modified organisms (GMOs), particularly transgenic crops and microorganisms. These trials assess potential environmental and health impacts under confined and controlled conditions before the organism can be considered for commercial release. With the expansion of biotechnology applications, especially in agriculture, pharmaceuticals, and industrial processes, the need for scientifically rigorous and ethically sound biosafety research trials has become increasingly important.
13.1.1. Scope of Biosafety Research Trials
1.1. Definition and Objectives
Biosafety research trials are confined, stepwise, and monitored field or laboratory-based studies designed to evaluate the safety, stability, performance, and unintended effects of GMOs. The overarching objectives include:
• Assessment of potential risks to human health, non-target organisms, and the environment.
• Evaluation of gene stability, trait expression, and environmental adaptability.
• Monitoring of gene flow and potential invasiveness or weediness.
• Determination of agronomic efficacy under field conditions.
• Data generation for regulatory dossiers and risk assessment reports.

A field visit to innovative farming system models would involve observing and learning about different approaches to agriculture that aim to improve efficiency, sustainability, and profitability. Here’s a breakdown of what such a visit might entail, the types of systems you might encounter, and the potential benefits:
Objectives of a Field Visit
• Practical Learning: See firsthand how innovative systems are implemented and operated.
• Knowledge Exchange: Interact with farmers, researchers, and experts who are using these systems.
• Inspiration & Idea Generation: Identify potential adaptations and applications for your own farm or region.
• Networking: Connect with other individuals and organizations interested in sustainable agriculture.
• Assessment: Evaluate the real-world performance of different technologies and practices.

The Aquatic Resources Research Institute (ARRI) was established to conduct research & answer important impending questions associated with the nation’s aquatic resources, like conservation of marine organisms, marine science, oceanography, aquaculture, biotechnology etc. It also works for transferring or sharing the knowledge to public, for guiding towards sustainable development.

Sichang Marine Science Research & Training Station: (SMaRT) Chonburi Province

Thailand This is another unit of the ARRI. It was established in 1979, in Chonburi Province Thailand.

Fieldpea is animportantrabi pulse crop which is highly productive and is grown for food, feed as a vegetable. There are two types of peas grown in India viz., vegetable type in which grains arevery sweet when green and become wrinkled ondrying, and grain type where grains are generally white and round. Green seeds of the grain type are not so sweet as in thecase ofvegetable type. The dry grains areconsumed in various forms such as chat, chhola, dal, vegetable and flour. Green seeds are used as fresh, frozen or canned vegetables. The cultivation of grain type is confined to northern and central parts of the country.

It is high protein (20%) crop with all the essential aminoacids important for normal activity of living organisms. The fractional composition is also favourable the most easily assimilated water soluble protein from mature pea seeds varies from 36 to 87% and in green matter from 65 to 82%. Pea contains 4 mgpro-vitamin A, 300 mgvitamin C, 3 mgB₁, 1.5 mgB₂and 1.2 mgpantothenic acid per 1000 g fresh seed weight. Also, it contains 1.1% fat, 2.2% minerals, 4.5% fibre and 56.5% carbohydrate. It is rich in phosphorus. Green pea and the immature pods of pea are typified by a high level of active lipotropic antisclerotic substances-choline and inositol.Choline deficiency may lead to the development and growth of malignant tumors.

Ficus carica L, one of the oldest plant species in China, is abound in Shandong, Xinjiang, Jiangsu province. Fig belongs to the family Moraceae and genus Ficus. It is native to Middle East region (West Asia), but now it is widely distributed in Asia and North America.

Cultivars/Varieties: Depending upon the nature of flowers and the method of pollination there are four distinct classes of fig- i) Common fig or Adriatic fig ii) Capri fig, iii) Smyrna fig and iv) San Pedro fig. Kadota, Mission, Adriatic, Brown turkey, Celeste and Conadria are some important varieties of common fig.

Uses

Fig is consumed fresh or dried, preserved, candied or canned. Fresh figs are very delicious, wholesoms and nutritious and used as dessert or for making jam. Due to its highly perishable nature it is dried and marketed. The fruit fresh, or dried is valued for its laxative property. Dried and ground fig can be used as a substitute for coffee.

Fig (Ficus carica  Linn.)  also called ‘Anjeer’ is a nutritive and delicious fruit. Its tree is native to western Asia. It is rich in calories (269), protein, and calcium (higher than milk), iron and fibre content. The small deciduous plants of fig are grown in different parts of the country. Fig has been cultivated since ancient period (4000 BC.) and well known through out the world. It is originated in Middle East and naturalized in many parts of the world. Fig tree plantations cover 426,244 ha. area in the world with an overall yield 1070676million tones. The largest fig growing countries are Turkey, Egypt, Iran, Greece and Algeria (Pasqual and Ferreira, 2007). It is also grown in some parts of Australia, California, New- Zealand and Argentina.

Fig is one of those fruits which are known to mankind since early ages. Legend maintains that the Fig was the “Autumn Fruit’ as revealed by the Greek Goddess, Demeter, and the tree is still held sacred in most parts of the Mediterranean. The fig’s nutritional value is so high that it is often referred to as the ‘Fitness Fruit’. It is a rich source of dietary fiber. It contains a good amount of vitamins and various useful minerals like iron, calcium, magnesium, copper, etc. The matured fruit has a tough peel either pure green, green suffused with brown, brown or purple. The interior is a white containing a seed mass bound with jelly-like flesh.

Stem-borer: Batocera rufomaculata, B. rubus, Olenecamptus bilobus:Cerambycidae

These are large dark brown adult beetles that lay eggs in loose bark.  Grubs bore into the trunk and make tunnels in branches and main trunks.  This causes drying and wilting of the branches. Adults of O. bilobus are pale whitish with long serrate antenna.
 
When bark is suspected to have the grubs, try mechanical removal of them. Paste the tree trunk with mud paste containing insecticides like chlorpyriphos or carbaryl. In endemic areas, spray the bark with Carbaryl 4gm /l, Malathion one ml/l, or Chlorpyriphos 2.5ml/l

The common fig, (Ficus carica L.) is a fruit of warm temperate zone. It is one of the oldest fruits known to man and is mentioned by well known Greek writers Homer and Plato. Mention about this fruit is in the earliest chapter of Bible. Figs belong to family Moraceae, which include many tropical fruits and ornamental species. The fruit is known botanically as ‘syconium’ in which the flowers are borne on the inner walls of a hollow receptacle. It is one of the most salt and drought tolerant amongst fruit trees. Fig is a moderate sized deciduous tree in subtropics but performs as evergreen in tropics. Branches are irregular, shoots develop at base of trunk, leaves are very broad, ovate and long stalked. Fruits mostly long stalked, pear shaped with a velvety or glabrous skin, yellow, brown, purplish or black in colour. 

Genus : Ficus 
Species : carica L.
Family : Moraceae
Chromosome No. : 2n = 26

Fig along with fruits like date palm, grape (vinifera) and olive was regarded as an important food crop of the ancient civilization that developed in the Mediterranean region. The fig description occurred prominently in number of songs as well as in the mythological and historical events that took place at that time. Fig is thought to be native of southern parts of Arabian peninsula, Italy, Balkan and USSR region. Fig was in cultivation as early as 300 BC and from Arabian peninsula it spread to Turkey, Syria, Iraq and later to many subtropical parts of the western hemisphere.

• Excel and Candia are suitable for HDP (2.5 m × 2.5 m)
• Candia is suitable for drying purpose.
• Excel is suitable for canning purpose.
• Deanna is suitable for table purpose.
• Fig is one of the first fruit to be preserved by drying.
• Salt and drought-resistant crop.
• Ficus carica is gynodioecious spp.
• Caprifig is monoecious spp.
• Common fig is pistillate.
• Excessive irrigation or heavy rains during ripening result in fruit cracking and producing of insipid fruits.
• Cultivar – Merselies, Black Ischia, Kabul, Banglara, Lucknow, (Dinkar – an improvement over Daulatabad).

Fig, Ficus carica grows in both mild temperate climates and in the tropics. In India, it is a minor fruit crop and the commercial cultivation is mainly confined to Maharashtra, Gujarat, Uttar Pradesh, and Tamil Nadu though is slowly spreading to warmer areas of Northern parts of the country. Very few insect pests come under the major category, the description of which is provided below:

Stem borer, Batocera rufomaculata (Cerambycidae: Coleoptera)

It is commonly known as mango and fig borer. The adults of this pest bear long serrated antennae and are also called as longicorn beetles. The adults get attracted to light. The female cuts the tree bark and lays eggs singly into these cuts, laying a total of up to 200 eggs. On hatching the larvae start to tunnel into the sapwood of the trunk or branches. The larvae pupate inside the tunnel and the adult comes out of pupae by cutting a circular hole. Frass comes out

After the patient has been radiographed, the exposed X-ray film is processed to produce the consistent quality radiographs. Film processing can be manually, or use an automatic film processor.  Manual film processing is a multi-stage process involving five basic steps in processing X-ray film: 
    i)    Developing 
    ii)    Rinsing 
    iii)    Fixing
    iv)    Washing
    v)    Drying. 

I. Filtration

Filtration is a process of separation of precipitate from solution. Filtration is used to remove impurities from a solution (or) to isolate a solid.

Filtration may be defined as the separation of a mixture or solution into component parts. The resulting components may be pure or may be solutions or mixtures. In water/wastewater treatment filtration technique is used for removing suspended solids, dissolved solids and organic matter.

Creating and sustaining a healthy aquarium depends on the correct setup and operation of filtration, aeration, and heating systems. These components function collectively to maintain clean water, adequate oxygenation, and consistent temperatures—key elements for the health and comfort of aquatic life.
Filtration systems clear debris, neutralize toxic substances like ammonia and nitrites, and provide a home for beneficial bacteria that fuel the nitrogen cycle. Options include internal filters, canister models, sponge filters, and hang-on-back units, each ideal for different tank capacities and setups.
Aeration equipment—such as air pumps, bubble stones, and diffusers— boosts dissolved oxygen and enhances water movement, which is especially critical in well-stocked or densely planted aquariums and during warmer periods when oxygen tends to deplete. Heaters are essential for tropical tanks, maintaining water temperatures typically between 24–28°C. A stable temperature supports healthy fish metabolism, immune response, and breeding activity. Together, these systems are the core of a functioning aquarium. Choosing the right equipment and maintaining it regularly ensures optimal conditions for both fish and plants.
TYPES OF FILTERS: INTERNAL, EXTERNAL, SPONGE, CANISTER
Aquarium filters come in various types such as internal, external (canister), sponge, and hang-on-back (HOB) filters. Internal filters operate from inside the tank, while external canister filters function outside. Sponge filters work using an air pump that moves water through a foam medium. HOB filters are mounted externally on the tank’s back.

a. Balance Sheets or Net worth Statement

Balance sheet is the list of assets and liabilities owned by a business. It helps to calculate the growth in net worth of the business by calculating the change in assets less the change in liabilities. They represent the financial foundation on which the business is built.

The term ‘balance sheet’ implies some sort of balance as part of the document. That balance represents the relationship between assets on one side, and liabilities on the other, and the basic accounting principle that assets always equal liabilities plus equity. Since it is simply a list of assets owned and debts owed, at a given time, with monetary values attached, we must understand the concepts of assets and liabilities.

Assets are resources owned by or owed to the business such as dairy, equipment, real estate, and notes receivable. Assets are those parts of the business that are owned or controlled. They include any property/resource owned by a person or business e.g. cash, land, buildings, dairy, farm equipment and dairy-related share. Assets are usually listed on the top or on the left hand side of the balance sheet. They are classified in following ways

A TTO needs a planned budget of five years to sustain it in the long term. This involves budgeting the infrastructure, manpower, research, and outreach programs. The budgetary needs of a TTO will be based on the size and scope of the TTO and the maturity of the parent institution it caters to. The initial years will be focused on capacity development, the appointment of experts, and the establishment of processes of intellectual property management. The mature TTO will generate income through the returns of the licensing agreements and the collaborative efforts with the industry. Nevertheless, external funding through grants and government schemes plays a vital part, particularly in the initial years. The planned budget ensures long-term stability and development of the TTO.
9.1 Budgetary heads
9.1.1 Operational expenditure
Operational expenditure refers to the ongoing costs incurred by a TTO to maintain its day-to-day operations. This includes the cost of maintaining the office, including rent, power and utility bills, computer and network infrastructure, patent management cost, and administration charges. The filing and legal charges also fall within this category. The overheads will be a heavy burden if not planned with finances properly. A TTO has to be provided with a properly planned operational budget that covers the daily operational expenses. The operational expenses help the office perform effectively, sustain the employees, and effectively manage IP. The operational expenses that the budget normally covers include:

Investment Appraisal Techniques

A financial evaluation/ appraisal of Project considers the possible compensations of completing the Project against the anticipated expenses. The assessment of the project will rely on several factors, including the Size of the project, time span of project etc. The motivation behind the financial evaluation is to decide if the project is advantageous, contrasting its expenses and its expected normal advantages. These methods are primarily designed to evaluate the effectiveness of a new project. This investment evaluation technique includes Payback Period, Internal Rate of Return (IRR), Net Present Value (NPV), Accounting Rate of return (ARR), Profitability index etc. Each of these techniques evaluates the project from various angles and provides very useful insights. Investment appraisal techniques are divided in two parts namely, discounted cash flow methods and non-discounted cash flow methods.

Non-Discounted Cash Flow Techniques

Future cash flows are not brought to their Present value through Non-Discounted Cash flow methods. Non-Discounted Cash flow methods are also categorized into the following two techniques.

Sources of agriculture/ Livestock finance
Finance for agriculture can be obtained from formal and informal sources Formal sources
Credit co-operatives
Commercial banks
Government
Regional Rural Banks
Informal sources
Money lender
Friends and relatives
Traders
Landlords

a. Financing the dairy enterprise

Dairy rearing provides triple benefits of income, employment and nutritional security to the society and is important source of subsidiary income to small/marginal farmers and agricultural laborers. Finance is a prerequisite and of paramount importance for setting up of a dairy enterprise whether a dairy farming unit for milk production, sheep or goat unit/piggery unit, dairy/poultry processing unit etc. Decisions about credit are often most important judgments that people in the agricultural industry must make. These decisions often determine whether individuals operating in input, production, processing, and services based dairy enterprise would succeed in making profit.
