The term hydrogeomorphology can be divided into three terms hydro- means water including both surface and groundwater; geo- means the earth and morphology- is the surface expression of the features in the form of landforms. This means that the hydrogeomorphology is dealing with the aspects of water, rocks and earth’s morphological features (land). Of these water and land are most important natural resources for human beings.

Water is synonymous with life. This is a natural resource and an absolute necessity for the survival of the living beings. Human beings have an organic relationship with water. For living and livelihood, human beings solely depend upon the availability of water. They have an inalienable right on water. This is a community resource and cannot be made a tradable commodity, violating normative law of nature. Water is among the most precious gifts of nature to mankind. Most of the ancient towns of the world grew on the banks of the river, and some of the ancient civilizations are known by the names of rivers. Rivers have always been important sources of drinking water and the means of sustaining human, animal and plant life. Whenever one is dealing with water resources development and utilization, it has to be kept in mind that not only quantity of water but also quality of water is very important. The well being and development of our society is dependent on the availability of water.

1. Relative Water Content

Relative water content (RWC) is an important parameter to measure the water status of plant tissue. High RWC, under moisture stress, denotes ability of plants to tolerate drought. (Ritchi et al. 1990). RWC and water potential have often been reported as indicators of drought tolerance (Schonfeld et al. 1988).

Leaf water status may be estimated by measuring the RWC following Barrs and Weatherlay’s (1962) method as given below:

Plant hormones and growth regulators are compounds that influence flowering, aging, root growth, prevention or promotion of stem elongation, prevention of leaf emergence and/or leaf fall and many other physiological processes. These substances produce major growth changes at a very low concentration.

Hormones are endogenously produced substances in plants while plant growth regulators may be synthetic compounds (i.e. IBA and Cycocel) that mimic naturally occurring plant hormones or they may be natural hormones that are extracted from plant tissue (e.g. IAA).

These growth regulating substances, most often, are applied as a spray to foliage or as a liquid drench to soil around a plant’s base. Generally, their effects are short-lived and they may need to be re-applied in order to achieve the desired effect.

Plant growth regulating substances are normally classified into five groups viz.: (i) Auxins, (ii) Gibberellins; (iii) Cytokinins; (iv) Ethylene; and (v) Abscisic acid.

For the most part, each group contains both naturally occurring hormones as well as synthetic substances. Physiological functions of each and every group of growth regulating substances are given below in brief:

Place of Microorganisms in Living World

Haeckel’s kingdom Protista

E.H. Haeckel, 1866 proposed this concept. Apart from plant and animal kingdom, the third kingdom “Protista” was developed by him. The protista includes unicellular organisms that are typically neither plant nor animal. These organisms, the protists, include bacteria, algae, fungi and protozoa. Bacteria are referred as lower protists and others are called as higher protists.

Whittaker’s five kingdom concept

R.H.Whittaker (1969) proposed the concept of five kingdom. He divided the living things in to 5 kingdoms.

The pathogenicity of an organism varies form mild attack to severe fatal attacks. The host has many mechanisms to resist or to avoid the pathogens apart from immune systems. One or few of these will be activated when the pathogen enters into the body. Following are some of the listed natural host defense mechanisms.

Abstract

Coral reefs, the marine representatives of tropical forests, coupled with the sea grasses contribute considerably to the coastal productivity. Damages to these ecosystems will immediately affect the fishery productivity of the region. Due to this, the long-term ecological impact of the recent tsunami will be a serious set back to the local, national and regional economy than the immediate losses. Andaman and Nicobar reefs represent the second largest coral reef formation next to the Great Barrier Reef and are also comparable to the coral reefs of Indonesia and Philippines in terms of diversity of species and associated floral and faunal components. The recent mega – subduction of the Indian plate below the Burmese micro – plate in Andaman – Sumatra region has not only deepened the southern and uplifted the northern group of Andaman – Nicobar islands but also created a disastrous tsunami on Dec 26, 2004. While such tectonic changes are expected to cause longterm changes in the coral reefs of Andaman, Nicobar group of islands, the tsunami has damaged the coral reefs instantaneously. However, the coral reefs of the Gulf of Mannar and Palk Bay are not much affected by the tsunami by virtue of their geographic position in the shadow region of Sri Lanka.

Regeneration capacity of the soil is enhanced with the sowing of MVS which provides ideal condition for regeneration. It creates green cover / dry leaf cover in the top soil (35-40 cm height) which will facilitate the multiplication of inoculated beneficial microbes in the soil.

Multi Varietal seeds sowing techniques

MVS contains seeds of three to four crops belonging to each category viz., cereals, pulses oilseeds, nitrogen fixing green manures and spices and condiments. The seeds of above crops may be mixed in different proportion based on their growth habit and seasonal requirement. For example in the summer the following mixture can be practiced with each of 1-1.5 kg each.

Abstract

The tectonics of the geological past from Archaeozoic to early part of Cenozoic era has been studied due to their penetrative documentation in the form of folds and faults. But the tectonic history of the latter part of the Cenozoic era (i.e Pleistocene period) has remained a matter of conjecture owing to the poor response of the rocks to Pleistocene movements. In the present study the authors presented a model for the Pleistocene earth movements of South India through the study of river migration, coast line changes and lineament fabric derived from the space borne photographs.

In the area of study, the northerly migration of Paleru and Pennar and southerly shift of Palar, Ponnaiyar and Cauvery rivers, marine regressions restricted within this segment and the closely spaced crest line fractures suggest a lineament controlled E-W trending Quaternary upwarping along Mangalore-Madras alignment. Similar E-W cymatogeny is inferred in the southern tip of the Peninsular India on the basis of once again such observations. Such E-W trending Pleistocene arching phenomenon suggests a N-S oriented regional compression which could be related to the collision of Indian plate with Tibetan plate.

INTRODUCTION

Coastal zones are always dynamic and active, because of the multivariate morpho tectonic and morpho dynamic processes, viz: tectonic, fluvial, marine and aeolian which act in varying degrees and duration along the coasts. As these geomorphic / morpho dynamic processes act in varying permutations and combinations in different segments of the coasts, the land - ocean interactive phenomenon vary greatly in time and space, which in turn frequently and dynamically alter the coastal environment, and cause fragility to the coastal ecosystems. Further, as the coastal zones act as the junction between the Continents and the oceans, even mild earth movements exhibit exemplified expressions in land - water distribution pattern along the coasts. The green house effect and the much apprehended sea level rise and the disasters like cyclones also contribute in their own way in accelerating such land - water distribution / land - ocean interactive phenomenon.

Tillage management and seedbed preparation is crucial for crop establishment, growth and ultimately, yield. Typically, the aims of cultivation are to incorporate crop residue, bury weeds and loosen soil to allow appropriate soil–seed contact, easy flow of nutrients, air and water and unimpeded root penetration and crop growth (Hermawan and Bomke, 1997; Bengough et al., 2006). The use of tillage to prepare seedbeds and the subsequent benefits are well documented. However, the amount of tillage and best practice in terms of optimumsoil physical properties specifically for the establishment period has received less attention in comparison. The influence of a seedbed can vary greatly in terms of soil aggregation and subsequent porosity. This soil arrangement, therefore, has direct impacts on soil temperature, water content, oxygen availability and strength, all of which have the potential to affect the performance of the seedbed and its ability to provide an adequate environment for crop establishment. In a review, Braunack and Dexter (1989) stated as summary of previous works conducted on soil aggregation that aggregates will exhibit differing physical and chemical properties depending on the size of the aggregates, thus influencing the suitability of a seedbed for germination, emergence and root development, by influencing factors such as intra- and inter-aggregate aeration. Schjønning and Rasmussen (2000) found that cultivation methods can have large impacts on surface soil layers, altering both strength and pore dynamics (air and water filled), which can restrict plant growth. The relationship between soil physical properties and the plant root systems are vitally important in this process since they directly affect seedbed quality (Awadhwal and Thierstein, 1985; Aubertot et al., 1999; Dexter, 2004).

Among the pulses, rajmash is one of the high potential pulse crops with a yielding potential of 18 to 20 q per ha. Rajmash or French bean (Phaseolus vulgaris L.) is a short duration non–traditional grain legume and one of the precious and highly relished pulse crops of North India. Rajmash is known by various names viz., French bean, rajma, haricot bean, field bean, kidney bean, snap bean, pole bean etc. It is an important winter vegetable grown both for tender pods and dry seeds, which form a rich source of crude protein (21.25%), fat (1.7%) and carbohydrates (70%). Besides, it contains 0.16 mg iron, 1.76 mg calcium and 3.43 mg zinc per 100 g of edible part (Jasvinder Kaur and Mehta, 1994). The fresh pods and green leaves are used as vegetable. The antimetabolites of dry beans needs removal by cooking and soaking in water.

Introduction

In chemical laboratories, the use of acids, alkalis and some hazardous and explosive chemicals is unavoidable. In addition, some chemical reactions during the analysis process may release toxic gases and, if not handled well, may cause an explosion. Inflammable gases are also used as a fuel/heating source. Thus, work safety in a chemical laboratory calls for special care both in terms of the design and construction of the laboratory building, and in the handling and use of chemicals.

For chemical operations, it is also necessary to provide special chambers. The air temperature of the laboratory and work rooms should be maintained constant at 20–25°C. Humidity should be kept at about 50 percent. Temperature and humidity often affect soil and fertilizer samples. Temperature also affects some chemical operations. Hence, maintaining the temperature and humidity as specified is critical.

Introduction

Any computer that has Microsoft office excel in it can operate this statistical calculator. Operating system requirement is Windows 7 or its higher version. Usually looking at a data we become nervous and start thinking that how to analyse the data using computer programme, how to write the report of the research analysis etc. This newly developed statistical calculator will remove the fear of data analysis and make our life easy. This calculator will get the data analysis done within a very reasonable computing time.

This chapter introduces a new statistical calculator which provides a step-by-step guide to data analysis of the research data generated in agriculture, biological sciences and in other fields (Singh and Chaudhary, 1985; Chandel, 1998; Bhattacharya and Chowdhury, 2010). The process used to develop the program is quite involved with statistical theories and is not understandable to those who do not have any background in statistics and data analysis. Here we will explain the procedure adopted and the programme used, step-by-step so that it becomes easily comprehensible. We have provided examples in each spreadsheet for analysis. Data analysis with this statistical programme is not really difficult. According to the draft format required for analysis, you only need to arrange and enter the raw data. It does not require much information and knowledge about the formula used as well as the program developed to analyze the data (http://www.sbear.in/).

Introduction

The coastal tract of peninsular India extends from Rann of Kutch in Gujarat to Malabar Coast in Kerala on the western coast and from Coromandal coast in Tamil Nadu up to Sunderban delta in West Bengal on the eastern coast. The eastern coast is generally characterized by a wider coast line when compared to its western counterpart. Coastal ecosystem in India occupies an area of about10.78 million hectares (1,07,833 km²) extending in nine states. It also occupies considerable area underLakshadweep and Andaman and Nicobar group of Islands. The extent and distribution of coastalarea have been shown in Table 1.

ABSTRACT

Colchicine, one of the most widely used alkaloids is synthesized in Gloriosa species, a plant of great medicinal importance. The seeds, tubers and leaves of six different species of Gloriosa were phytochemically investigated for alkaloids and were found to contain colchicine and colchicoside. These alkaloids were isolated and quantified by HPLC analysis. This is the first report of alkaloids in Gloriosa plantii, Gloriosa lutea, and Gloriosa vuchuria. The colchicine and colchicoside content of the Gloriosa species was found to be organ dependent as there was statistically significant differences (P<0.05) between different organs but not among different species under study. The total alkaloids are organ as well as species dependent as there were statistically significant differences (P<0.05) between all the species as well as organs of different species of Gloriosa under study and its organs.

Random variable: A random variable is a variable that assumes numerical values associated with the events of a random experiment whose outcomes cannot be predicted with certainty. For example, Height of rice plants in a field; seed weight; No. of tillers per rice plant.

A random variable is of two types:-

1. Discrete random variable: The random variable which takes only countable values i.e., integral values. For Example, Number of tillers per rice plant. Here there can be finite no. of values between any two values.
2. Continuous random variables: The random variable which takes values within intervals. These values cannot be counted but can only be measured. Here there can be infinite no. of values between any two values for example, Height of rice plants in field; seed weight.

The word ‘monsoon’ is derived from the Arabic word mawsim meaning season. The Arabs during their travel towards India recognised that by June strong southwesterly winds commence over the Arabian Sea and bring a lot of rains to the subcontinent. The term was first used in English in British India and neighbouring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. In the Indian subcontinent, monsoon is one of the oldest weather observations, an economically important weather pattern over June through September every year, and the most anticipated weather event and unique weather phenomenon. Due to its effects on agriculture, flora and fauna, and other economic, social, and environmental effects, a monsoon is keenly followed and studied. It has significant impact on the overall well-being of subcontinent residents.

The term ‘monsoon’ is customarily used in India to refer to the rainy season during the northern hemisphere summer from June to September and is traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation, but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea. Now the term monsoon has been broadened to include almost all of the phenomena associated with the annual weather cycle within the tropical and subtropical land regions of the earth.

Intergovernmental Panel on Climate Change (IPCC) describes monsoon as a tropical and subtropical seasonal reversal in both the surface winds and associated precipitation, caused by differential heating between a continental-scale land mass and the adjacent ocean. India Meteorological Department defines it as the seasonal reversals of the wind direction along the shores of the Indian Ocean, especially in the Arabian Sea, that blow from the southwest during one half of the year and from the northeast during the other half.

The definitions include major wind systems that change direction seasonally. The cyclic change of wind and rain can be separated into the summer monsoon period characterised by warm and humid southwest winds, and the winter monsoon period characterised by dry and cool northeast winds. In fact, monsoon systems are a major feature of the general circulation of the atmosphere in subtropical latitudes of most regions of the world.

Maharashtra is the third largest state in terms of area in the country located in the north-centre of peninsular India. It links the southern part of the northern plains to the southern peninsula. Maharashtra occupies the western and central part of the country with total 3.08 lakh sq. km geographical area and has a long coastline stretching nearly 720 kilometers along the ARabian Sea. The prominent physical trait of the state is its Plateau character, which has up to 1350 meters high altitude. Physiographically this state may be divided into three natural divisions-the coastal strip (the Konkan), the Sahyadri or the Western Ghats and the Plateau. The Sahyadri mountain ranges provide a physical backbone to the state on the west, while the Satpuda hills along the north and Bhamragad-Chiroli-Gaikhuri ranges on the east serve as its natural borders. It has a geographical area of 307713 sq. km and is bounded by north latitude 15°40’ and 22°00’ and east longitudes 72°30’ and 80°30’.

NBSS & LUP has divided the state into 356 soil mapping units and published a map of the soils of Maharashtra. It has broadly categorized as soils of Konkan coast, soils of Western Ghats, soils of upper Maharashtra, soils of lower Maharashtra. The soil status of Maharashtra is residual, derived from the underlying basalts. In the semi-dry Plateau, the regur (black-cotton soil) is clayey, rich in iron and moisture-retentive, though poor in nitrogen and organic matter. The rainy Konkan and the Sahyadri Range, the same basalts give rise to the brick-red laterites, which are productive under a forest cover, but readily stripped into a sterile varkas when devoid of vegetative cover. The soil in the Deccan Plateau is made up of black basalt soil. This type of soil is rich in humus. The soil is commonly known as the black cotton soil because it is best suited for the cultivation of cotton. The volcanic action which had taken place in the Deccan region has given rise to the soil texture and composition. These igneous rocks break down into the black soil which is very fertile. The Wardha-Waliganga river valley has old crystalline rocks and saline soils which make the soil infertile. This type of soil has a natural resistance to wind and water erosion because it is rich in iron and granular in structure. A very important advantage of this type of soil is that it can retain moisture. This makes the soil very reactive to irrigation.

In domestic animals, skeleton (Fig. 1-1) is a framework that is formed of bones, cartilages and ligaments binding together giving the specific shape, form and support to the body. In addition, the skeletal framework surrounds the major cavities of the body giving protection to other soft visceral organs of the body. There are three major parts of skeleton in the animal body (1) the axial skeleton (2) the appendicular skeleton and (3) the splanchnic skeleton.

The axial skeleton consists of the skull, vertebral column, ribs, and sternum. The appendicular skeleton consists of the bones of fore limb and hind limb

The splanchnic skeleton includes some of the bones embedded in the substance of visceral organs in the body such as os cordis in ox and os penis in dog.

Bones

The bones forming the skeleton of the body are of different shape, size, form and the constituting tissue material. The number of different types of bones of any species may differ in various stages of the growth of the animal. So also the numbers of various bones differ from species to species.

Cutaneous muscle

In the cervical region of ox, the cutaneus muscle, cutaneus colli is poorly developed. It is in the form of a narrow strip on the ventral part of the neck. It arises from the ventral median connective tissue strip of the superficial fascia and extends cranially covering the cervical part of the deep fascia. The fibres of this muscle fan out dorsolaterally and form the aponeurosis with the cervical fascia and join the cutaneus facei.

Fascia

The major groups of muscles of the cervical region are covered by the thick superficial layer of fascia. The fascia is abundant and well developed in the cervical region of the ox. The fascia of the neck is in two layers, the superficial and deep. The superficial fascia is attached to the skin, whereas the deep fascia is again in two parts, the superficial and deep parts. The superficial part covers the superficial structures in the neck viz. the trapezius and brachiocephalicus muscles in the dorsolateral aspect and the jugular canal with jugular vein, and the rhomboideus muscles on the ventrolateral aspect of the neck. The superficial parts of the deep layer of cervical fascia of two sides meet at the median line both, dorsally and ventrally. The deep part of the deep fascia is attached to the vertebrae and the longus colli muscle on either side at the median line and covers the trachea, oesophagus, carotid artery etc before joining ventrally.

Cutaneous muscle

The cutaneous muscle of abdomen and pelvis is the continuation of cutaneous muscle of thorax. This has been described under the muscles of thorax.

Abdominal fascia

Beneath the skin in the abdominal region, there are two layers of fascia, the superficial and deep, similar to those of the fascia of thoracic region.

The superficial fascia is next to skin. It is fused dorsally with the thoracolumbar fascia. Cranially it is continuous with the superficial fascia of shoulder and arm and caudally with that of the gluteal region. In the inguinal region it forms part of fascia of penis in male and of mammary glands in female animals. At the flank, it continues as fascia of thigh region.

The deep fascia forms the abdominal tunic. It is especially well developed as a thick sheet of tunic in the ventral and the adjacent lateral parts of the abdominal floor. It extends cranially over the ribs and external intercostal and the caudal digitations of the serratus thoracis muscles. Caudally it is attached to the external angle of the ilium and thoracolumbar fascia. The suspensory ligament of prepuce in males and that of the mammary glands (udder) in females is an extension of this tunic. It strongly supports the abdominal muscles to bear the weight of abdominal viscera.

The hind limb (Fig. 6-1) is termed as pelvic limb and it consists of four segments-the pelvic or hip region, thigh, leg and the pes region. The skeleton of pelvic region is formed by the pelvic girdle (os coxae). The skeleton of thigh region is mainly formed by a long bone (thigh bone) the femur and at its lower extremity is a short sesamoid bone, the patella. The leg region is formed by two long bones, the larger one the tibia and the smaller one the fibula. The last segment, the pes has three subdivisions as tarsus, metatarsus and digits. The tarsus has five short bones arranged in two rows on par with the carpus of fore limb. The metatarsus is constituted by two bones of which one is a long bone called the large metatarsal and the other a short small rudimentary bone the small metatarsal bone. The last part of the hind limb is the digits which are constituted by six phalanges and six sesamoids like those of the forelimb.

The damage to food grains in the storage may be caused due to insect attack, mould, fungi, bacteria, rodents, heat and moisture. The value of grain for milling purposes and human food is directly correlated with the amount of insect contamination present. The immature stages of rice and granary weevils, lesser grain borer, Angoumois grain moth and occasionally the flat grain beetle, cadelle, rust red flour beetle and saw toothed grain beetle live inside the kernels where they are hidden from view until they emerge.

Grain from casual inspection appears to be in good condition but may contain enough internal infestation which render it unfit for human food or unfit for purchase for future sale as milling stock. In general, millers have found that wheat with more than 0.5 per cent of infested kernels is unfit for milling. The need for a rapid and accurate method of estimating insect contamination in grain offered for sale has become more and more important to both grain dealers and millers.

Methods for Estimation of Damage

In order to assess the damage caused to food grains due to any one or combination of various factors; physical, chemical and micro-analytical methods are employed according to the necessity and information required. Various methods have been employed by field workers as well as by laboratory technicians in estimating damaged grains in food grains with particular reference to detection of insect infestation which alone cause maximum damage. These methods have been described below.

Objectives

• Better understand the process and different stages of meiosis.
• Prepare your own specimens of onion root in which you can visualize all of the stages of meiosis.

Principle

Meiosis is a type of cell division in which the number of chromosomes is halved (from diploid to haploid) in the daughter cells, i.e., the gametes. It occurs in cell that produce gametes in sexually reproducing organisms. The division is completed in two phases, meiosis I and meiosis II. Meiosis I is a reductional division in which the chromosomes of homologous pairs separate from each other. Meiosis II maintain same number of chromosomes, hence, is called as equational division. Stages of meiosis can be observed in a cytological preparation of the pollen mother cells of the anthers of f lower buds.

Objectives

• Find out the number and types of gametes and gametic recombination in monohybrid, dihybrid and trihybrid crosses.

Principle

Gametes are reproductive cells that join together to form a new cell called a zygote during sexual reproduction. Pollen in seed-bearing plants, is the gametophyte producing male gamete. Female gametes (ovules) are included in the ovary of plant. At maturity a sexually reproducing individuals forms the gametes. Homozygote generate only one form of gamete. Homozygous referring to a diploid cell or organism possessing two identical alleles of a specific gene (e.g. AA or aa). Heterozygote generate different types of gametes. Heterozygous referring to a diploid cell or organism possessing two different alleles of a specific gene (e.g. Aa).

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.

In most of higher organisms including animals, the aspect of sexes has been normally confined to males and females which exist separately or even in the same individual. An individual possessing both male and female reproductive organs is usually referred to as hermaphrodite. In plants, where staminate (male) and pistillate (female) flowers occur on the same plant, the term used is monoecious. The most common plants under monoecious form are cucurbits. However, majority of the flowering plants have male and female parts within the same flower and this situation is referred to as hermaphrodite. There are relatively less numbers of plants having male and female flowers located on different plants and this is termed as dioecious condition. Among the common cultivated crops known to be dioecious are asparagus, date palm, hemp, hops and spinach.

So far, we have seen the examples in which mode of inheritance of a particular character is tied to the behaviour of the nucleus or more specifically to the chromosomes. In other words, transmission of a character and its appearance in the individuals can be predicted from the knowledge of chromosome segregation and independent assortment. This analogy gets further strengthened on the ground that the DNA has been considered as the basic genetic material and practically all the cellular DNA is localized in the chromosomes. It has also been seen that DNA does not produce an organism alone but obviously depends upon an already existing medium in order to function. Thus, genotypic effects may considerably get modified by the environment. In the cell itself, one important source of environmental effect is the cytoplasm immediately surrounding the nucleus. The components of the cytoplasm may show wide variation between the individuals and therefore it cannot be ruled out that a genotype in one cytoplasm may function somewhat differently than the same genotype placed directly into another cytoplasm. It is well known fact that the cytoplasmic contribution of one of the parents in form of an egg is considerably larger than the cytoplasmic contribution of the other parent in form of sperm. For example, cross-fertilization between two strains capable of producing both sperm and eggs, leads to contribution of ‘A’ genotype and ‘a’ egg cytoplasm in one case and of ‘B’ genotype and ‘b’ egg cytoplasm in the other case. Thus, the cross-fertilized diploid zygotes have two possible genotypic-cytoplasmic combinations, namely, AB-a, and AB-b depending upon which strain provides the egg. If the egg is contributed by the A parent, then the genotype of the progeny shall be AB-a, and if the egg is contributed by the B parent, then the genotype of the progeny shall be AB-b. If each such cytoplasm produces a unique phenotype, then AB-b would have the same b phenotype as BB-b individuals. Such effects produced by the egg cytoplasm are termed as maternal effects.

Abstract

Information and Communication Technology (ICT) played and continue to play pivotal role in better decision making of farmers for plant health management under the climate change scenario. For judicious plant health management by farmers through the use of ICT tools (viz. interactive Kiosk, Mobile Apps, Whatsapp, Webportal), information need and information access network to be assessed. Based on farmers’ information need and network, information delivery tree should be designed in ICT tools. Under this backdrop this research work was carried out among the farmers of Bhagalpur district of Bihar. The sample size was 120. From the study it was noted that the major information needs of the farmers were seed availability, crop disease management, insect pest management, weed management and weather information and pesticide application. Farmers were enthusiastic to improve their knowledge on insect pests and disease identification and management. Specifically, farmers need information on insect pest management of wheat (aphid), maize (stem borer), vegetables (fruit borer), pulses (pod borer) and oilseeds (aphid) and also disease management of wheat (leaf blight and spot blotch disease), maize (Turcicum leaf blight), vegetables (wilt and leaf spot) and pulses (wilt disease). Farmers decision making was positively and significantly correlated with crop disease management(0.196*),insect pest management of crop(0.208*) and weed management(0.239**). Through the Path Analysis it was noted that farmers decision making on disease management was mediated by the variables - Bihar Agricultural University-Kisan Diary, Mobile Apps(Bihar Krishi Apps) and Kisan Salahkar. So, it can be concluded that these much needed information should be provided to the farmers though different ICT tools and extension personnel should be trained to operate these ICT tools for accelerated use of ICT tools by the farmers.

I. General Information

Use of computers into the design process has benefited landscaping industry in several ways. There are several advantages in using computers for design. The most important factor is that the computer can store and handle large amount of engineering data, which can be used in various stages of design, development and manufacturer, like conceptual design, analysis, component design, documentation, process planning and manufacturing. The product development approach using the computer aided design and computer aided manufacturing (CAD/CAM) results in better and consistently good quality products invariably at a lower cost, with the attendant benefits of faster development of different variants of the product or model. The following table highlights the relative advantage of human designers and computers.

8.1 INTRODUCTION

Natural methods of vegetative propagation include strategies that the plants have developed for self-multiplication or perpetuation. Natural vegetative propagation is mostly a process found in herbaceous and woody perennial plants, and typically involves structural modifications of the stem, although any horizontal, underground part of a plant (whether stem, leaf, or root) can contribute to vegetative reproduction of a plant. In crops like ginger, turmeric, onion, garlic, gladioli, and dahlia etc. they continue to grow from buds that are present on the surface of the stem. In some plants, like sweet potato adventitious roots can give rise to new plants. In Bryophyllum and Kalanchoe, the leaves have small buds on their margins. On detachment from the plant, they are able to grow into independent plants and they may also start growing into free plants if their leaves were made to grow in the soil. In nature, vegetative reproduction occurs through underground stems, sub-aerial stems, bulbils, leaves and even roots.

India is the primary centre of origin of brinjal. Decandolle (1904) reported it as native of Asia. In Europe it is not known earlier (before 17th early). According to N.I Vavilov, the egg plant originated in Indo–Burma region and china and spread to South Europe, china and Japan. Vavilov (1951) suggested China a centre of origin of brinjal. Crop is restricted mainly to South and South-East Asia, Southern Europe, China and Japan. Wild brinjal types are available in Southern Coastal area of Africa.

It is cool season crop cultivated throughout the world. It is extensively grown in temperate zone and is restricted to cooler altitudes in tropics and winter season in sub tropics. It is rich source of proteins (25.6%), amino acids and sugars. It goes well with other vegetables in vegetable dish.

Among beans, the most popular bean is French bean and it has wider distribution and larger gene pool. Various names are associated with cultivars viz., Snap bean, salad bean and green bean and all these names associated are with beans of vegetable types. The names haricot bean, dry bean and navy bean are applicable to pulse types. String bean, dwarf bean and pole bean applicable to growth forms. It is known as Rajmah in Hindi, Tingalawari in Kannada and Fras bean in Punjabi. Cultivars preferred for Canning, frozen and freeze-dried are having round pods. Fresh market cultivars are flat or oval shaped. Yellow pod cultivars are also grown. Generally fresh market cultivar yields higher in temperate region than in tropical region. Beans are said to be antidiabetic and good for bladder burns, cardiac, carminative, diuretic.

Origin and Distribution: Phaseolus vulgaris was domesticated in Central America about 7000 years ago and it is also thought to be domesticated in Brazil and Northern Islands and was introduced to Europe in 16th century. Vavilov (1951) reported that Phaseolus vulgaris originated in South Mexico and Central American centre of origin. The first cultivar has been selected in Peru. From Peru it spread to Europe and to Asia. Wild species P. aboriginus in North West Argentina is considered as the wild progenitor of French bean. Based on growth habit, crop can be classified into pole type, semi pole type and bush type. Former varieties are more string types. American origin of P. vulgaris is questioned by De Candolle (1584). Southern part of Mexico and Central America are considered to be primary centre of origin. While secondary centre lies in Peru-Bolivian-Ecuador of South American continent. In Europe, French bean spread rapidly in 16th and 17th centuries and reached England by 1594. From Europe, it was introduced to India during 17th century (Simmonds, 1976).

Garden Features

In order to break the monotony and to enhance the beauty, any garden should contain components of varying nature. Some features are not only essential but also an important part of the visual design. Besides this, any garden feature allows to discover and save the creative ideas on a wide sheet of natural green carpet. Following are important features.

1. Arbour

It is a recessed or somewhat enclosed area shaded by trees or shrubs that serves as a resting place in a wooded area. In a more formal garden, an arbour is a small structure with vines trained over lattice work on a frame, providing a shady place. A true arbour includes a bench sheltered underneath for seating, which distinguishes it from a trellis. There are different types of arbours such as archway, wood, plastic, metal, etc. Arbour can be developed at several locations of the garden such as entrances at the main gate, pergola area, patios area, pathway entrance, pool area, etc.

Definition: Annuals are the group of plants which complete their life cycle in one season or in one year.

Annuals are commonly known as seasonal as they complete the process of life like germination, growth, flowering and seed formation in one season and finally the plant wither out. Annuals are widely used for garden decoration, cut flower and pot plants. They are frequently grown as bedding plants and in rock gardens on the sides of lily pool and in shrubberies. Annuals are planted in the winter, summer and rainy season and die in a season or within a year.

Introduction

The chrysanthemum is one of the most beautiful and perhaps the oldest flowering plant. It is commercially grown in different parts of the world. Chrysanthemum is commonly known as Guldaudi. In Dutch cut flower auction, chrysanthemum ranks second after rose. It is preferred practically due to vast range of shapes and sizes of flowers, brilliance of colour tones, long lasting floret life, diversity of height and growth habit of the plant, exceptionally hardy nature, relative ease to grow all the year round and versatility of use.

It is one of the most important traditional flowers of India mainly used as a potted plant, loose flower, cut flower and as border plant in the garden. Chrysanthemum cinerariifolium inflorescences are of considerable importance in the manufacture of pyrethrin insecticides.

Introduction

In modern garden, dahlias are extensively used for exhibition, garden display and decoration. It can be grown in any form in the garden; in beds, in borders or even in mixed borders along with other plants. It grows well in pot also. For border purpose dwarf growing type are preferred, while in pots usually large flowering dahlias are grown. The long stemmed flowers of various forms and colours are used in flower arrangement. Dahlias make excellent cut flowers, which typically last about a week in the house and are also used in making garlands.

The tubers of dahlias contain appreciable amount of insulin and fructose and small quantities of phytin and benzoic acid which are of medicinal and nutritional value.

12.1 INTRODUCTION

French bean (Phaseolus vulgaris L.) is one of the most important legume vegetables grown for its tender green pods for fresh consumption, processing and dry seeds. The pods are slender, 10-25 cm long, straight or slightly curved with prominent beak. Seeds are kidney shaped, elongated and white, red, purple or blackish in colour or mottled. The vegetable is in great demand in cities and is grown both commercially and in home gardens. Its major area is confined to hills, where it is grown for green pods. Punjab, Jammu and Kashmir, Gujarat, Karnataka, Tamil Nadu, Uttar Pradesh and Himachal Pradesh are the main states where it is being cultivated on large scale. Dry bean seeds are an excellent source of cheap protein and many cultivars contain 22-23 % protein. Hundred grams of edible fresh pods contain 91.4 % water, 1.7 % protein, 0.1 % fat, 0.5 % mineral matters, 4.5 % carbohydrates, 50 mg Ca, 28 mg P and 1.7 mg Fe. Its 100 g dry seeds contain 9.6 % water, 24.9 % protein, 0.8 % fat, 3.2 % mineral matters, 60.1 % carbohydrates, 60 mg Ca, 433 mg P and 2.4 mg Fe. In India, it is mostly grown for fresh consumption, while in USA it is grown for processing in large quantities. Dried beans are rich in protein and closely compared with meat. Phaseolus oborigineus is the progenitor of French bean. They are capable of utilizing atmospheric nitrogen with the aid of bacteria found in the nodules on the roots of the plants. Four cultivated species are seen under the genus Phaseolus, i.e., Phaseolus vulgaris—common red kidney bean, Phaseolus coccineus—scarlet runner bean, Phaseolus lanatus— Lima bean, Phaseolus acutifolius var. latifolius—Moth bean or Tapery bean. All the species are self-pollinated except lima bean which is often cross-pollinated and Phaseolus coccineus is generally cross-pollinated and long day plant.

Introduction

National Gene Banks are now entering into an era of increased activity and responsibility, particularly for managing their own indigenous germplasm activities extending from collection to actual use of the genetic variation in crop improvement programmes. However, these tasks must be achieved with limited resources in best possible time frame. The core collection offers a potential opportunity to meet these challenges. Recognising that the sheer size of a germplasm collection could deter its use, Frankel (1984) proposed that it could be pruned to a ‘core collection’, which would represent, “with minimum repetitiveness, the genetic diversity of a crop species and its relatives”. The core collection consist of a limited set of accessions derived from a germplasm collection, chosen to represent the genetic spectrum in the whole collection, and including as much as possible of its genetic diversity (Brown, 1995). The remaining accessions would not necessarily be discarded but would be managed as a ‘reserve collection’. The proposal, the rationale, purposes and general principles of core collections have been critically examined (Brown, 1989 a and b). As to the size of a core collection, sampling theory of selective neutral alleles in finite populations indicate that about 10 % drawn randomly from the whole collection was relatively efficient in retaining its allelic variation (about 70 % retained). The core collection concept has attracted considerable discussion and debate in the past and has met criticism in many areas. Most of these concerns appear to arise from misuse or misunderstanding of the core approach and a number of core collections have been established during the past decade.

10.1 Introduction

The agriculture sector is also transforming through technological intervention and advancements drastically to improve several processes and crop and livestock production systems. These advancements have resulted in minimizing operation and production costs, reduction of environmental impact and optimization overall production cycle. The major issue in the agriculture sector is human-intensive operation and non-availability of sufficient labor on time. The on-field task like fruit harvesting, intra-row weed control which is supposed to be more difficult to perform by the traditional machinery and manually. This has made to think to introduce the autonomous tractors and robotics platform in field operation. Timely activities and treatment play an important role in agriculture and agriculture production. The farmers generally face many problems in performing the task on the field due to various limitations. The cost is one of the main parameters which need to keep the farmer in a competitive market and reduce the cost of operation as low as possible. Also, the growing population demand more and more food which put pressure on the agriculture sector to raise crop production. In this situation, agriculture robots can play an important role to address the challenges in the farms. A robot can professionally perform the task and can automate the tasks which are difficult for manual labor. These are used in the agricultural lands and they are also completely autonomous. These robots are used in several applications in agriculture and can also work autonomously.

The robotic system has been widely used in industrial production and warehouses in an almost controlled environment. In the early 1960s, the agriculture and forestry sector initiated research into driverless vehicles with a focus on automatic steered system and autonomous tractors. Robotics has made an impact on agriculture and forestry since past few years. The purpose of minimizing the damage to the growing zone of soil tends to cater to the application of automatic vehicle guidance. The interest in the development of robotics system in agriculture has led many experts to explore the possibilities to develop more rational and adaptable vehicles based on a behavioural approach.

Abstract

Goat farming was the important part from the economy point of the view; especially in the Mediterranean and Middle East region where goat is also called as “Cow of poor man”. Goat milk have unique compositional characteristics like, lower ethanol stability, higher content of short- and medium-chain fatty acids. It is a rich source of calcium, phosphorous, chlorine, and vitamins. It is highly digestible and has a mild laxative effect. Along with these, who are suffering from anemia, osteoporosis and malabsorption, they should consume Goat milk. Goat milk is a functional and nutraceutical property as it both nutritional and additional health benefit such as easily digestible, boost immunity and metabolism, anti-inflammatory and anti-carcinogenic to consumer this lead to increasing demand for goat milk and derived dairy products. Goat milk can be used to manufacture a wide variety of products, including fluid, fermented, frozen, acid coagulated, and dehydrated milk products.

The aim of this chapter is to highlight the physical and chemical properties, nutritional and health benefit of Goat milk. Goat milk based some popular products are also discussed in order to provide some basic information regarding the value addition of Goat milk.

Abstract

Sheep milk is one of the superior quality of dairy foods and it is also considered as nutritional powerhouse. The beneficial role of sheep milk results from its fatty acid, immunoglobulin and non-immune protein contents. Apart from different dairy products and functional foods; this milk is used in anti-ageing and cosmetic soap preparations. In India Sheep make a valuable contribution to the livelihood of the economically weaker sections of the society. In our country the major portion of sheep milk is consumed as fluid milk and in certain areas converted into ghee and dahi.

A garden has a number of elements which give shape to its breath-taking view. Both animate and inanimate elements are included to achieve a beautiful garden The living elements are lawns, rock garden, water garden, sunken garden, hedges, edges, shrubs, topiary, flower bed, specimen plants, pergola and arches, while the inanimate elements, also called as adornments, are stones, road, footpaths, seats, lamps, lanterns, steps, bridges, huts, swings, fountain, cascade, bird bath, clock tower, umbrellas, sculptures etc.

The bael (Aegle marmelos (L.) Corr.) is indigenous to India and it is also called as Baelpatra, Bengal quince (John and Stevenson, 1979), Indian quince, golden apple, holy fruit, bel, bilwa, bela, maredoo and other dialectal names in India. Hindus used the leaves to worship Lord Shiva (Bilwa Patra) and keep them on Shivling and they consider it is very auspicious and to get the blessings of Shiva. The fruits form a vital ingredient of holy offerings to the God and Goddess through holy pyre (haven). In history, the mention of bael tree is traced to Vedic times (C 2000 BC. to C 800 B..) within the Yajur Veda.
