1. Introduction

Pummelo is considered as largest fruit among all the Citrus species from the Rutaceae family. It is also known as shaddock, papanus or chakotra. Although C. grandis (L.) Osbeck is more frequently used, however C. maxima (Burm.) Merr. is considered as correct under the International Code of Botanical Nomenclature (Singh and Navneet, 2017). It is considered as one of the four true species (natural, non-hybrid) of Citrus. The ltypical large size, thick rind is one of the causes for slow acceptance of pummelo in international market. However, it is presently considered as important fruit due to presence of various bio-active compounds related with human health and nutrition. The word ‘pummelo’ was originally derived from the Dutch word ‘pompelmoes’. The fruit is also named as ‘Shaddock’ after a Captain Shaddock who was believed to have introduced the fruit in Barbados on an East India Company ship on its way to England in the 17^th century. It is known by different names by different communities residing in India such as chakotra (Hindi), batabi lebu or jambura (Bengali), robab tenga (Assamese), nobab (Manipuri), ser trawk (Mizo), soh myngor or soh bah (Khasi), rabab tasing (Adi), papanas (Gujarati), chakota (Kannada), kambili naranga (Malayalam), pamparapanasa (Telugu), metukki or pampalimaku (Tamil) and bampara (Marathi) [Anon, 2019]. Pummelo can be distinguished from grapefruit by its larger size fruit, thicker albedo and the bunch bearing habit of grapefruit can also be considered for distinguishing it from pummelo (Scora et al., 1982). The crop is believed to have originated from South and Southeast Asia and it is now cultivated in many tropical and semi tropical countries. The top ten world producers of pummelo and grapefruit are USA, China, Mexio, South Africa, India, Argentina, Turkey, Cuba, Brazil and Tunisia (FAOSTAT, 2010). It is also cultivated in in Bangladesh, Cambodia, Chile, Philippines, Vietnam, Sri Lanka and Nepal. There is no report of its commercial cultivation in India till date; rather it is mainly grown in homestate gardens across the country including UP, Punjab, Maharashtra, Tamil Nadu and Karnataka. However, maximum genetic diversity in pummelo germplasm is found in North Eastern Region, West Bengal and Bihar (Singh et al., 2015).

1. Introduction

Valeriana jatamansi Jones is considered to be highly endangered medicinal plant found mainly in northern part of Himalayan region. Although it is also found in all temperate regions of world except in Australia (Jain, 1968; Polunin and Stainton, 1987; Bennet, 1987). It is grown in Himachal Pradesh, northern part of U.P., Sikkim and newly introduced in West Bengal Darjeeling region by us. It is enlisted in the endangered category by IUCN (Kaul and Honda, 2000) and it is enlisted as an endangered species in the national medicinal plant board, New Delhi (www.nmbp.nic.in). The plant was reported to be found in fragmented populations in different places of Kashmir Himalayan hilly region like Dara, Sonamarg, Harwan, Gulmarg, Ferozpur, Pahelgum, Yusmarg, Shajnar (Naqashi and Dar, 1982-86). It is found to be in the margin of extinction from the world though it is widespread in the temperate regions of whole world except Australia (Nayar and Sastri, 1998). Indiscriminate collection of rhizomes from the plants made potential threat of its existence in some previously founded localities (Wyatt, 1981; Nayar and Sastri, 1998; Airi et al, 2000; Nautiyal et al, 2003, CAMP, 2003).

1. Introduction

Cucurbits are group of plants belongs to family Cucurbitaceae which are mostly creeping or crawling in nature and distributed in tropical and subtropical zone of the globe. The family cucurbitaceae has around 120 genera and more than 800 species (Swarup, 2016). It holds the highest rank amongst all other plant families considering number and percentage of species used for human consumption either as fruit of the tender leaves and stems. Cucurbits have diverse daily use such as salad (cucumber and long melon); dessert (watermelon and muskmelon), curry or boil (bottle gourd, bitter gourd, sponge gourd, ridge gourd, summer squash, squash melon, pumpkin etc.); candy (wax gourd); pickles (pickling cucumber, pointed gourd); jam (pumpkin); utensil (bottle gourd), musical instruments (bottle gourd). From plant breeding point of view, the crops are cross pollinated and entomophilies.

1. Introduction

Chirata (Swertia chirayita) belongs to the family Gentiniaceae, a potential medicinal plant used as bitter tonic in treatment of fever and for curing various skin diseases, is a perennial herb and distributed throughout the eastern Himalayan region of India. The plant is a native of temperate Himalayas, found at an altitude of 1200-3000 m (4000-10000 ft), from Kashmir to Bhutan and in the Khasi hills at 1200-1500 m (4000 to 5000 ft). It can be grown in sub-temperate regions between 1500 and 2100 m altitudes. It is used in traditional medicine to treat numerous ailments such as liver disorders, malaria, and diabetes and are reported to have a wide spectrum of pharmacological properties. Its medicinal usage is well-documented in Indian pharmaceutical codex, the British, and the American pharmacopeia’s and in different traditional medicine such as the Ayurveda, Unani, Siddha, Horopathy and other conventional medical systems. This ethno medicinal herb is known mostly for its bitter taste caused by the presence of different bioactive compounds that are directly associated with welfare of human health. The increasing high usage of Swertia chirayita, mostly whole plant, as well as the illegal overharvesting combined with habitat destruction resulted in a drastic reduction of its populations and has brought this plant to the verge of extinction. The increasing national and international demand for Swertia chirayita has led to unscrupulous collection from the wild and adulteration of supplies. The bitterness, antihelmintic, hypoglycemic and antipyretic properties are attributed to amarogentin (most bitter compound isolated till date) 1, swerchirin, swertiamarin and other active principles of the herb. Due to the high demand, this plant is being cultivated in many places of Darjeeling district both for domestic use within India and for exporting purpose. During our roving survey (2011-2014), it was observed that this high value medicinal plant facing a number of diseases (like seedling blight, leaf spot, Leaf blight etc.), ultimately, cultivation of Swertia chirayita is getting hampered. The quality of plant is affected due to the occurrences of diseases as whole plants part being used as medicinal purpose and also affects the marketing scenario; the demand of good quality chirata is increasing at a rate of 10% annually. To harvest the benefit of megabiodiversity zone of eastern Himalaya needs urgent attention to combat the upcoming epidemic of diseases of chirata. Here, we are trying to throw some light related to present status of diseases of chirata and standard management practices.

“Tell me what you eat and I will tell you what you are. The destiny of people depends on the nature of its diet.”

Milk is the only product which is considered nature’s almost perfect food. It is treasure house of unlimited nutrients. It is considered best and ideal food by virtue of possessing almost all the nutritional factors, viz., fats, proteins, carbohydrates, minerals and vitamins. They are not only of higher quality but are present in milk in such form and proportion that their digestion and assimilation in the body is very efficient. Milk also plays a supplementary role in our nutrition. If it is included in our diet it enhances digestion and assimilation of nutrients of other food products. This is the reason that it is kept in high esteem as a food and is called the nectar for living beings.

Milk is the first taste of food for whole mankind. It establishes the mother-infant bond and is a life promoter. Of the many fluids that biology offers milk is perhaps the most versatile in terms of its use– as food, as a growth stimulant and as a defense package to the user. To the infant mammal – be it a mouse, calf or a human child, mother’s milk is more than a source of energy and nutrients. It contains a wide variety of substances that defend the growing infant against infections.

Milk, a perfect blend of nutrition and palatability, plays an important role in preserving mental and physical health. Milk has long been recognized as the most wholesome and complete single food available in nature for health and as a medicine, both preventive as well as curative. Ancient chronicles as recorded in the Upnishads, Puranas and Vedas extol the beneficial and therapeutic properties of milk and milk products. It has been stated that cow milk, dahi and ghee impart knowledge and radiance, cure heart trouble and anaemia besides other bodily diseases.

Milk is a complex colloidal dispersion, the physical and physicochemical properties of which depend on intrinsic compositional and structural factors, extrinsic factors such as temperature, and post-milking treatment.

There is no clear dividing line between physical properties and physicochemical properties. However, physical properties may be thought of as the measure of the bulk behaviour of milk and of how milk interacts with energy, while physicochemical properties are measures of how bulk behaviour and energy interactions depend on the constituent colloidal particles, molecules, atoms and ions in milk.

Knowledge of physical properties is of importance particularly in the technological and engineering design and control of milk processes and processing equipment. Knowledge of physicochemical properties provides the basis for the design of modern methods of milk analysis, determination of milk microstructures and elucidation of the complex chemical reactions that occur in milk.

In the dairy industry measurements of the physical properties of milk and milk products are made to secure data necessary for the design of dairy equipment (e.g., heat conductivity and viscosity) to determine the concentration of a component (e.g., specific gravity to estimate solids-not-fat or freezing point to determine added water), or to assess the extent of a physical or chemical change (e.g., titratable acidity to follow bacterial action or viscosity to assess aggregation of protein micelles or fat globules). The great advantage of physical measurements for such purposes is their speed and simplicity as well as their potentialities for automation.

Use of physical property to measure concentrations or changes in degree of dispersion demands knowledge of the contribution of the several components to that property. Furthermore, the natural range of variation of the property in milks or products is of major interest. The precision and suitability of possible methods of measurement are also of prime importance.

A  disaster  (from  Latin  meaning,  “bad  star’)  is  the  impact  of  a  natural  or man-made event that negatively affects life, property, livelihood or industry often  resulting  in  permanent  changes  to  human  societies,  ecosystems  and environment.  The  event  itself  is  not  a  disaster;  it  is  the  impact  that  is  a disaster. Their possibility of occurrence, time, place and severity of the strike can  be  reasonably  and  in  some  cases  accurately  predicted  by  technological and scientific advances. Hence, we can to some extent reduce the impact of damage  though  we  cannot  reduce  the  extent  of  damage  itself.  Despite  the severe impacts suffered – including trauma, starvation, dehydration, infection, disease and shock-animals are often the silent victims of disasters, and there is a real need around for the provision of effective training and management programmes to ensure that their survival and welfare are adequately accounted for. This demands the study of disaster management in methodical and orderly approach.The World Health Organization (WHO) defines a ‘disaster’ as any occurrence that  causes  damage,  destruction,  ecological  disruption,  loss  of  human  life, human suffering, deterioration of health and health services on a scale sufficient to  warrant  an  extraordinary  response  from  outside  the  affected  community or area (WHO, 1999). It is an event, concentrated in time and space, which causes social, economic, cultural and political devastation and which affects both individual people and communities (Kumar, 1998). 

What is Performance Appraisal?

Performance Appraisal (PA) is the process through which an individual employee’s behaviour and accomplishments for a fixed time period are measured and evaluated. The major purpose of measuring and evaluating is to assess the worth or value of an employee. Performance appraisal is a systematic and objective way of judging the relative worth or ability of an employee in performing his task. Performance appraisal helps to identify those who are performing their assigned tasks well and those who are not and the reasons for such performance.

Milk processing plants involve processing of raw milk into products like market milk, cheese, butter, ice cream, condensed milk, dried milks and traditional dairy products. The by-products processing includes buttermilk, whey and its derivatives. Dairy effluents contain dissolved sugar, protein, fat and minerals. Spills and leaks of products or by-products, residual milk or milk products in piping and equipment before cleaning, wash solutions from equipment and floors, condensate from evaporation processes and cheese trimmings are some of the sources of dairy effluents in a dairy plant. The key parameters are the biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids, total dissolved solids etc. Common dairy waste techniques include grease traps, oil water separators for separation of floatable solids, equalization tanks. Biological treatment consists of aerobic and anaerobic process.

Dairy rearing is central to livelihoods and survival of millions of people of India. It is estimated that approximately 100 million people derive their live hood from dairy rearing as primary or secondary source of income. Dairy related activities help to maintain regular in flow of income for these households. Small farmers in India generate nearly half of their income from dairy and the value of cattle represents a significant part of their wealth, so the death of cattle poses a significant risk and affects farmers’ net worth and income.

a. Type of risks to dairy based livelihoods

Large animal’s are expensive and thus carry higher risk exposure. Dairy losses due to the disease, accident, theft, natural calamity can cause significant losses to these household. Sometimes owners are forced to sell their animals due to loss due to incurable disease/ disorder/ fodder and water scarcity and they are unable to rebuild their stock. Many times animal losses force them into poverty trap from where they are unable to recover.

Risks faced by dairy owner’s dairy dependent livelihoods can be classified into two broad categories

Interest Rate: Provisional Interest rate @ 15.75% p.a. has been taken for evaluation of the project report. However, the exact interest rate will be decided by the sanctioning authority on the date of sanction.

Disbursement of loan: Funds for fodder cultivation and civil construction should be disbursed first. Development of sheds and fodder plots should be completed within 3 months from first disbursement. Then disbursement of 1^st Batch cow (10 animals) will be done. Last disbursement for 2^nd Batch cows (10 animals) should be done after 5-6 months of purchase of 1^st batch cows.

Insurance: The animals and other assets (sheds, equipment) must be insured. Wherever necessary, Risk / Mortality fund may be considered in lieu of dairy insurance.

Management of Calf

Management before birth

    ·    As calf management begins before birth, a few days before the calf is born, the pregnant cow is transferred to a maternity paddock, which should be near the homestead (for closer observation), well watered and free from physical objects.
 
    ·    The signs of imminent parturition (calving) include filling of udder with milk and is turgid, vulva swollen with a string of mucus hanging from vagina.
 
    ·    Insemination records can also be used to estimate the expected calving date.

Vegetables constitute a substantial part of human diet supplying vitamins and minerals, in which other food materials are deficient. India has emerged out as the second largest producer of vegetables in the world. More than 25% of fruits and vegetables are damaged by the attack of insect-pests (Pradhan, 1964).Vegetable crop is damaged by both sucking as well as chewing insect-pests. Sucking pests are aphids, whitefly, jassids and bugs attacking in initial stage whereas chewing pests like borers, infesting in flowering and fruiting stage. Sucking pests may transmit the viral diseases which cause severe loss in yield in tomato and okra crops. About 13-14 % of total pesticides used in the country are applied on vegetables. Average pesticide consumption in vegetables in India around 0.678 a.i. kg/ha. Maximum pesticide usage in chilli followed by brinjal, cole crops and okra. Global agro-chemical consumption dominated by fruits and vegetables, accounting 25 % of total pesticide market. Major insect-pests of different vegetable crops and their management are as follows:
 
Cole crops

Cabbage (Brassica oleracea var capitata) and Cauliflower (Brassica olercea var botrytis L) are grown in cold and moist climate. It is rich in minerals namely iron, magnesium, phosphorous and sodium. Cole crops were attacked by number of insect pests and cause heavy economic loss. The major insect pests are described below along with their management:

Okra Abelmoschus esculentus L.

Cotton Jassid Amrasca biguttula Ishida (Hemiptera: Cicadellidae)

Economic importance: Sucking pest cause damage during May to September. Adults are also found on plants such as potato, brinjal, tomato, etc.

Mark of identification and life cycle: Adults are about 3 mm long and greenish yellow during the summer, acquiring a reddish tinge in the winter. The winged adults jump or fly away at the slightest disturbance and are also attracted to light at night. Females lay about 15-38 yellowish eggs on the underside of the leaves, embedding them into the leaf veins. The eggs hatch in 4-5 days. Nymphs are wedge-shaped and are very active and complete five instars with 3-5 days in each instars. Adult live for 11days.

Nature of damage: Damage to the crop is caused by the adults as well as by the nymphs, both of which are very agile and move briskly, forward and sideways. They suck cell-sap from the underside of the leaves and pass through six stages of growth in 7-21 days. They feed constantly on the plant juice. The pest completes seven generations in a year. Damage symptoms: Injury to plants is due to the loss of sap and probably also due to the injection of toxins. The attacked leaves turn pale and then rust-red. With change in appearance, the leaves also turn downwards, dry up and fall to the ground.

Abstract: Trees are known to reduce growth and yield of crops under their canopy in agroforestry systems through competitive interaction. This chapter describes the mechanism of competitive interaction between Linseed (Linum usitatissimum L.) and Leucaena leucocephala (Lam) De Wit in an alley cropping system. To know the mechanism of competitive interaction in agroforestry, three competition situations are created: crop + Leucaena shrub neighbour, crop + L. hedge neighbour and sole crop. In this study competitive interaction is studied in an alley cropping system having two alley width sizes i.e. 4m and 8m. Sunlight at ground, soil organic C and total N are measured in all the competition treatments at different distances from shrub and hedge neighbors. Sunlight is not reduced in crop + hedge treatment like that in sole crop treatment. Sunlight is reduced in crop + shrub treatment (36 to 82%), being the highest in 4m alley and the lowest in 8m alley size. Soil organic C is high but total N is low in crop + hedge and crop + shrub neighbour than in sole crop treatment. Comparing the two competitive treatments (crop + hedge and crop + shrub neighbour) it is observed that growth rate (42 to 55%) and crop yield (71 to 72%) are reduced greater due to aboveground than belowground competition. Belowground competition is 3.6 times greater in 4m than in 8m alley, suggesting that spacing is an important factor, which regulates tree/crop competition so does the crop yield reduction in an agroforestry system.

ABSTRACT
Increased environmental pollution and high demand over supply for conventional fossil fuel sources have led to the exploration of other renewable energy sources. Out of the potential alternatives, methane has come up with a promising unconventional fuel source. Several technologies have been developed to establish methanation, including biomethanation, chemical methanation and gas-to-liquid technology. Several factors like process parameters, catalysts and reactors have been studied for process optimisation and making methane production commercially viable. Although methane as a greenhouse gas is a contributor to global warming, its combustion produces relatively ‘environment friendly’ gas CO₂, and H₂O. The released CO₂ is fixed into biomass by plant through photosynthesis process. Only rarely does methane combustion produces CO when combusted in an oxygen-limited condition. Thus, methane production and combustion are carbon neutral process. This chapter focuses on the application of methane as a source of alternate energy. Various technologies used, recent advances and challenges faced in methanation process are discussed.

ABSTRACT
The annual accumulating organic wastes generated through milling, brewing and various other agro-industrial and agri-processing activities in India amount to about 500 MMT. Most of these contain three major structural biopolymers, viz., cellulose, hemicellulose and lignin, a large proportion of which is carbohydrate and phenolic in nature. Massive accumulations of this kind of recalcitrant biomass not only deteriorate the environment, but also generate huge amount of potentially useful materials. Biological transformation has globally become increasingly popular among researchers and academicians in treating agricultural, industrial, organic and toxic wastes these days. About 60% by weight of the original pineapple fruit in forms of peeled skin, core, crown end, etc. resulting from the pineapple processing remains unutilised being discharged as waste, causing disposal and pollution owes. Of the 10% dry matter content of such waste, about 96% is organic and 4% is inorganic. Being rich in cellulose and hemicellulose, it can be a valuable resource for numerous value-added products by bioconverting it to valuable products, including bioenergy. Biomethane is one such energy resource that can be produced by valorizing pineapple wastes by employing various bioconversion technologies. This chapter focuses on the bioconverstion technologies to produce biomethane from pineapple wastes.

The following tests are used for microscopic evaluation of semen: 
    
12.1    Sperm motility
12.2     Per cent Live sperm
12.3     Sperm concentration

12.1 Sperm Motility

The following two methods of estimation of sperm motility are followed in routine practice:
 
12.1.1    Mass activity
12.1.2    Progressive sperm motility
12.1.1 Mass Activity

Mass activity can be defined as ‘en-mass activity of the spermatozoa in the semen, immediately after collection’. Mass activity is generally assessed by vigour of swirls and waves motion in undiluted semen under 20 X magnification and expressed on 0 to 5 scale.

Artificial insemination (AI) is the technique of placing sperm into a female’s uterus (intrauterine), or cervix (intracervical) using artificial means rather than by natural copulation. Modern techniques for artificial insemination were first developed for the dairy cattle industry to allow many cows to be impregnated with the sperm of a bull with traits for improved milk production. It is the first generation reproductive biotechnology which has revolutionized the animal productivity. It has now been established as cheapest and fasted mode of genetic improvement of livestock. AI can be done using fresh semen, semen preserved at room temperature, refrigerated (4ºC) and cryopreserved (-196ºC) semen. The use of AI with frozen semen has become very popular and is being successfully used throughout the country.

Introduction

India is an agriculture based country with 60% of the manpower employed in agriculture (World Bank, 2010). Few of the main environmental issues are soil erosion, water pollution from raw sewage and runoff of agricultural pesticides. There is a need to maintain a sustainable environment and a sustainable agricultural system.  Sustainable Agricultural system is a self sustaining system, is dependent up the ability to bring together and manage simultaneously the soil, water, plant and animal resources with the limitation of climatic and environment in such a way that the agricultural production/profitability can be maintained in the future too. So initiatives need to be taken to achieve a sustainable agricultural system. Tools have been developed to aid agriculturist, extension personnel and policy makers. The World Wide Web has made the tools easy accessible.

Introduction

Spatial planning tools brings together multiple users of the earth to make informed and coordinated decisions about how to use of resources  and helps to organize, analyze and present information from a number of different sources.  Thus, viewing from single interest or multiple use viewpoints is enhanced and can make a very important contribution to environment. Use of Remote Sensing (RS) and Geographical Information Systems (GIS) tools has the capacity to bring together experts from a variety of disciplines to address complex spatial problems.

Abstract

Accurate forecasting of the rice yields is very important for the organization to make a better planning and decision making. The aim of the study is to investigate the ability of neural network for yield prediction of rice in Andaman and Nicobar Islands. Field experiments were conducted at the various regions of Andaman and Nicobar Islands during 1980 to 2002 and data collected was subjected to Artificial Neural Networks (ANN) approach for developing a meaningful yield prediction for four varieties of rice C14-8, Quing Livan No.1, Taichung , Sen Yu, Jaya under island conditions with the objective to estimate the crop production a few days or months before harvesting of crop. The observations of all experiments viz., Varietal spectrum, Weather parameters , Yield components, Soil, Abiotic stressors, Biotic stressors for the period of twenty years from 1980 to 2002 were collected from the basic records of experimental field. All the data were used for training data set. Prediction of crop yield, mainly strategic plant of rice has been an interesting research area to agronomists since long for its importance in national and international economic programming. Application of ANN was found to be significant tool for prediction of yield in rice.

A DNA microarray is a multiplex technology used in molecular biology. It consists of an arrayed series of thousands of microscopic spots of DNA oligonucleotides, called features, each containing picomoles (10-12 moles) of a specific DNA sequence, known as probes (or reporters).

Data mining is becoming an increasingly important tool to transform the data into information. In recent years, data mining has been widely used in area of Bioinformatics for better understanding of gene expression, drug design, and other emerging problems in genomics and proteomics. Data mining is used to understand gene expression analysis, searching and understanding of protein mass spectroscopy data, 3D structural and functional analysis and mining of DNA and protein sequences for structural and functional motifs. For the first several hundred years of research in biology, the main bottleneck to scientific progress was data collection. Our new found data-richness, however, has shifted this bottleneck from collection to analysis. Biomedical literatures have been increased at the exponential rate. To find the useful and needed information from such a huge data set is a daunting task for users. Text mining is a powerful tool to solve this problem and it is used for biological knowledge discovery.

The choice of hormones and drugs acting on reproductive system are important as therapeutic agents during reproductive disorders like anoestrus, metritis, pyometra, repeat breeder, retention of fetal membranes, delayed puberty, ovarian disorders etc.  The administration of specific chemotherapeutic agent is of paramount importance in treating reproductive disorders in dairy animals.  The dosage, route, frequency and indications of chemotherapeutic agents acting on reproductive system are mentioned in tabular form as below.

Introduction

After the advent of Post Genomic era, Biological data is accumulating at an electrifying pace every day. Storage and analysis of these data serve as a major source for scientific research to understand the phenomena of origin, evolution and existence of various forms of life. The management of these data requires different statistical techniques used for retrieval, storage, analysis and extraction of precise information from small as well as large biological datasets. Application of statistical tools in Bioinformatics especially in fisheries data has been reported (Roy and Martha, 2008).

Influenza a Pandemics

Bioinformatics is the application of information technology to the field of molecular biology. The term Bioinformatics was coined by Paulien Hogewag, in 1978 for the study of informatic processes in biotic systems. Bioinformatics nowadays, entails the creation and advancement of databases, algorithms, computational and statistical techniques, and theory to solve formal and practical problems arising from the management and analysis of biological data. Bioinformatics deals with storing and searching of large biological data sets and analysis of these data sets using computers to determine various relationships. 
The rapid developments in genomic and other molecular research technologies and developments in information technologies have been combined to produce tremendous amount of information related to molecular biologists. Now bioinformatics has developed and deals with many other types of biological data like protein structures, sequence alignment, gene finding, genome assembly, gene expression profiles, structure alignment, protein structure prediction, protein–protein interactions and the modelling of evolution. Being an interface between modern biology and informatics, it involves detection, expansion and implementation of computational algorithms and some of the software tools used to provide applications primarily in agriculture and healthcare divisions. In developing countries, bioinformatics play a major role in agricultural area where it can be used for increasing the nutritional content, and increasing the volume of the agricultural products etc.

Two schemes of labeling are in common use today. One variant labels a single sample, either radioactively or fluorescently. Radioactive labeling is used, e.g., in conjunction with hybridization on nylon membranes (Lennon and Lehrach, 1991). The company Affymetrix synthesizes sets of short oligomers on a glass wafer and uses a single fluorescent label (Lipshutz et al., 1999). Alternatively, two samples are labeled with a green and a red fluorescent dye, respectively. The mixture of the two mRNA preparations is then hybridized simultaneously to a common array on a glass slide. This technology is usually referred to as the Stanford technology (David Duggan et al., 1999). Quantification utilizes a laser scanner that determines the intensities of each of the two labels over the entire array. Recently, companies like Agilent have immobilized long oligomers of 60 to 70 base pairs length and used two-color labeling.

The role of bioinformatics in genomics and molecular biology research can be likened to the role of intelligence gathering in battlefield. Intelligence is clearly very important in leading to a victory in the battlefield. Computational algorithms are the heart of bioinformatics as they enable predictions, understanding and interpretation of the data generated from laboratory experimental research carried by biologist. This article discusses one such approach called Decision tree induction and its application for generating rules from a dataset extracted from biological databases.

Decision Tree (DT) is one of the most popular choices for learning from feature based examples. They are especially attractive in data mining environment for several reasons. First due to their intuitive representation, the resulting classification model is easy to assimilate by humans. Second, DT does not require any parameter setting from the user and thus are especially suited for exploratory knowledge discovery. Third DT can be constructed relatively fast and accuracy of DT is comparable or superior to other classification models.

Keeping pace with latest technologies Central Institute of Freshwater Aquaculture (CIFA) has attempted to develop the following three databases on the following aspects for quick retrieval of information resources. The brief description of the databases is presented below for easy comprehension.

CD-ROM Database on Socio-Economic Aspects of Carp Culture in Kolleru Lake (Pictorial)

In the era of 21st century world is progressing fast towards the electronic media of communication and the real revolution has been brought about in the information technology. It has revolutionized the collection, storage and retrieval of information very speedily and accurately. One of the IT tools like CD-ROM (Compact Disc Read Only Memory) plays an important role in storing the huge data and can be easily carried to remote places. Since it is lightweight, pocket sized and can hold about 660 megabytes of data which is equivalent to 3 lakh pages. CD-ROM is a high capacity optical disc. It is 12 cm diameter, made of durable plastic with a reflective metal coating and lacquered surface. Considering all these advantages an attempt has been made to develop a database on socio-economic aspects of carp culture in Kolleru Lake which is immensely helpful to all scientific and farming community (Roy et al., 2004).

Abstract

The protein classification prediction is an important Problem in molecular biology, and one that has attracted a lot of attention, because there is a gap between sequence and structure of proteins from various resources. The proteins can be usually classified into one of the four structural classes; they are all-a, all-b, a/b and a+b. To address the problem of protein classification, many different algorithms and efforts have been made so far. In this paper, a new rule based data mining method for the prediction of protein structural classes is constructed using Rough Sets algorithm. Rough Sets Theory (RST) is a new mathematical approach to study the realistic information (Z. Pawlak, 1982). It focuses on knowledge reasoning by the whole set directly approximating to the incomplete and uncertain information. There are studies on the knowledge reduction and features selection of mass data. To apply rough sets algorithm, a decision table is constructed using Amino acid compositions and eight physicochemical properties data as conditional attributes. The generated decision rules after reducing the decision system can be used to classify new objects.The classification results of Rough Sets is verified by using self-consistency and jackknife tests on the datasets constructed by G.P. Zhou and comparison is made with some of the previous works.

Natural disasters are of meteorological or hydrometeorological origin. Disasters such as earthquakes and tsunamis are occasional, but rainfall-related hazards, flood or drought, are very frequent and thus call for proper monitoring of large-scale rainfall variation, and better manage- ment and planning to combat the problem(s). Variation in rainfall is very large spatially and temporally compared to any other atmospheric parameter, such as pressure or temperature. The large temporal variability in the Indian rainfall has produced frequent flood/drought and periods of above/below normal rainfall for several centuries past. Areas of high rainfall and runoff are flooded in the summer monsoon season whereas others face water stress and drought conditions. The influence of global warming on rainfall variations over India is reported in numerous observational (Singh et al., 1991, 1992) and modelling studies (Lal, 1994). 

Climate risk management in the semi-arid tropics (SAT) is one of the major challenges to achieving food security and development in India and large parts of sub-Saharan Africa and also in the case of Australia. Climate-induced production risk associated with the current season-to-season variability of rainfall is a major barrier in making rainfed agriculture sustainable and viable farm business. Since season outcomes are uncertain, even with the best climate information, farmers have limited flexibility in applying management with confidence. In fact in risky environments, farmers most often respond by adapting a risk averse strategy and are reluctant to invest in even risk reducing measures (Leathers and Quiggin 1991). In the SAT agro-ecologies, there are a limited range of enterprise or crop options to consider which may be further restricted by cultural traditions, food preferences or market opportunities.While there are fundamental differences between large scale commercial farms in Australia compared to the predominantly smallholder resource poor farms found in India, when it comes to climate risk management in the SAT, there are many commonalities. The purpose of this paper is therefore to (i) establish a framework for managing climate variability and transforming farming systems to be more resilient and sustainable for future climates; and (ii) provide some case study examples from climate risk management in low rainfall cropping system in Australia and consider how they may be applied in smallholder systems of the SAT.

The State of Andhra Pradesh in the present form came into being on June 2, 2014 as a result of the Andhra Pradesh Reorganization Act. The state has 13 districts out of which nine are along the coast of Bay of Bengal and four are land locked in the southern part. A part of Khammam district, which is now in the Telangana state, was also added to the East and West Godavari districts of the State of Andhra Pradesh. The existing data for these two districts do not include this part and this fact is to be borne in mind. The state has a geographical area of 1.602 lakh km2 with a population of 49.83 million. The state in the current form is more agrarian compared to the undivided state as about 62 per cent of population depends on agriculture as a source of livelihood. Yet, the contribution of agriculture to the state’s gross domestic product is only 17 per cent. Though the state is known as ‘rice bowl of India’, not all is well with agriculture in the state. Some parts, especially the coastal districts, are prone to incidence of cyclones and floods while some other districts, Rayalaseema districts, are chronically drought-prone. 

Importance of rice in Konkan area is characterized by heavy rains of 100 mm per week or so over an extended period and contributes 42.9 % of total rice production in the Maharashtra State. Rice is the only suitable crop that can be grown under puddled soil conditions, i.e. with standing water over bunded fields. Tansplanting method of rice is commonly followed by most of the farmers in this region. Puddled rice is said to be of assistance in mitigating the effects of floods. The problem of weeds is minimal in puddled rice culture. Thus, rice serves as a livelihood crop for millions of small, and marginal farmers in Konkan who can afford only low-cost technologies. Even though the crop is robust and versatile, it has faced drawbacks in terms of low yield and reduction in acreage. In Konkan region of Maharshtra, there are two agro climatic zones viz., North Konkan coastal zone comprising three districts viz., Thane, Raigad and Greater Mumbai and South Konkan Coastal Zone comprising two districts viz., Ratnagiri and Sindhudurg. Ratnagiri district receives the highest rainfall of > 3500 mm while Thane district receives the lowest rainfall (2000-2500 mm) in this region. Sindhudurg and Raigad districts receives 3000-3500 and 2500-3000 mm rainfall, respectively.

The Northeast Region (NER) of India consists of Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura, covering an area of 255168 km2. The area is characterized by rich biodiversity, heavy precipitation and high seismicity. Although the contribution from agricultural sector towards gross domestic product has declined, yet it remains the predominant sector for Indian Economy. Over 75% of the people of NE India directly depend on agriculture for their livelihood. Therefore, better performance of agriculture has a direct and multiplier effect across the economy of the region. Because of climate change the rain fed agriculture is facing a greater risk as it is resource poor and having limited flexibility for adaptation. Under changing scenarios there is increase in demand for fresh water and nutrient requirement, increase in soil erosion and nutrient losses affecting soil health, intensification of pest, disease and weed problems, reduction in nutritional quality and low input use efficiency. Continuous mono-cropping and the associated excessive tillage, inadequate erosion control measures and large scale slash and burn cultivation (Jhum) resulted in significant environmental damage and a non-sustainable crop production system in the region.

Natural disasters are extreme events within the earth’s system (lithosphere, hydrosphere, biosphere or atmosphere) which differs substantially from the mean, resulting in death or injury to humans, and damage or loss of valuable good, such as buildings, communication systems, agricultural land, forest, natural environment. They are a profound impact of the natural environment upon the socio-economic system (Alexander, 1993). This impact may be rapid, as in the case of earthquakes, or slow as in the case of drought. It is important to distinguish between the terms disaster and hazard. A potentially damaging phenomenon (hazard), such as an earthquake by itself is not considered a disaster when it occurs in uninhabited areas. It is called a disaster when it occurs in a populated area, and brings damage, loss or destruction. Natural disasters occur in many parts of the world, although each type of disaster is restricted to certain regions. Natural disasters are events which are caused by purely natural phenomena and bring damage to human societies (such as earthquakes, volcanic eruptions, hurricanes). Mitigation of natural disasters can be successful only when detailed knowledge is obtained about the expected frequency, character, and magnitude of hazardous events in an area. Many types of information that are needed in natural disaster management have an important spatial component.

Introduction

It is well known that, over 50% of requirement of food for the entire humanity is obtained from just three crops- rice, maize and wheat though 150 crops are commercialized globally. Ethnobotanically, over 7000 plants species are cultivated or harvested from the wild which represent immense agro-biodiversity. Most of these species are under exploited but have the potential for contributing to food security, health (nutritional/medicinal), income generation and environmental services. Examples include little millets which provide calcium and iron and vitamins like niacin and sulphur containing amino acids, having more fiber than rice and wheat. Some other species which have in the recent past contributed to income generation in Indian arid zone include ber, anola, karonda and gonda. Likewise the perennial grasses in this area are not only source of nutritious fodder but also the grains e.g. gramana (Panicum antidotale) are consumed during famine. They have acquired importance being alternative sources of income as also alternate life support system during crisis. They often have neutraceutical, medicinal uses or often multiple uses. Demand for traditional food in large multi-ethnic cities and metros have brought these species into sharp focus, Hence, these are being viewed now as potential candidate for diversification in the cropping system, conservation of bio-diversity, enhancing the limits of green revolution even during climate change and finally as provider of molecules for curing various ailments of men and animals.

Introduction

Low and erratic rainfall, extreme temperatures, long sunshine duration, high wind velocity, high evapotranspiration, low fertility of soil and paucity of water resources characterize hot arid region of India. Despite these hostile conditions, the region supports a large number of human and livestock population. However, the ever increasing human and livestock population and developmental activities exerts enormous pressure on natural resources and posing serious threat to sustainability of the region. In these hostile environmental conditions, several indigenous agroforestry systems are being practiced by farmers of this region (Shankarnarayanan et al. 1987). The agroforestry, which is a dynamic, ecologically based natural resource management practices that, through the integration of trees and other tall woody plants on farms and in the agricultural landscape, diversify production for increased social, economic and environmental benefits (ICRAF 2000). A number of studies have recognized the multiple benefits of agroforestry that include carbon sequestration, reducing forest degradation, biomass production, food security, income diversification, improvement and maintenance of soil biodiversity, provision of wildlife corridors, and a host of other ecological services and social benefits. In the last three decades, agroforestry has been widely promoted in the tropics as a natural resource management strategy that attempts to balance the goals of agricultural development with the conservation of soils, water, local and regional climate
