With the introduction of high yielding varieties and use of high analysis fertilizer in intensified agriculture under irrigation condition resulted in green revolution in our country. But continuous use of chemical fertilizer in indiscriminate manner without assessing soil also had adverse effect on productivity and environment. Though use of high analysis fertilizer ensured the high production but also resulted in acceleration of mining of native sources of nutrient. This has led to appearance of hidden hunger of several other essential nutrients and sustainability of our agriculture has become venerable.

Livestock production is an integral part of agriculture and plays a significant economic role in most developing countries. It contributes to poverty alleviation, food security and provides elements that are essential to the national economy. Livestock production accounts for 40% of the gross value of the agricultural production globally and this figure is likely to go up, as the demand of livestock products is increasing rapidly with the increase in income and urbanization (FAO, 2012). For poor farmers, animal ownership ensures varying degrees of sustainable development and economic stability. Livestock provide a stable cash reserve independent of inflation and are an important source of traction. Livestock are closely linked to the social and cultural lives of several million people. Quality and quantity of feed is essential for optimum animal productivity. Inadequacy of quality animal feed resources is most often the crucial factor for livestock production. The success of livestock is greatly dependent on continuous supply of good quality nutritious feed at competitive price. Poor nutrition of animals has been identified as the major constraints to animal production across the developing world (FAO, 2000). Feed is the major input cost in animal production system, accounting for 65-70% of the total rearing cost.

INTRODUCTION

Insecticide resistance poses a severe threat to agricultural productivity in India and in other countries of the world. Humans have had the ingenuity to develop thousands of pesticides to protect foodstuffs, livestock, and health and the use of these poisons has triggered a rapid evolutionary response in many target species and some nontarget species of invertebrates, microorganisms, higher plants and vertebrates. Insecticide exposure led to nullify their toxic effects through genetic selection for individuals with the biochemistry or behaviour. Continual development of new compounds and its greater use and increase in input insecticide cost is mainly due increase in resistance. Reduction in insecticide efficacy from insect resistance has major economic, environmental and human health implications. Integrated Pest Management (IPM) is a convenient descriptor for wide range of still-evaluating pest control program that emerged from chemical prophylaxis practiced. IPM theory has fostered a transition from primarily chemical control to programs tempered with biological information and input tailored to each agro ecosystem, crop and pest situation in production.

Tree tomato belongs to the family solanaceae, genus Cyphomandra and species betacea. The Cyphomandra genus is made up of about 30 species. Shaw (1996) has reported that Cyphomandra genus consists of 35 species confined to the New World tropics. They were earlier described under the genus Solanum. They can be separated from Solanum  by several characters, the most important being anther characters. In Cyphomandra in the anther the connective is thickened and expanded dorsally. As a result, it is clearly differentiated from the anther thecae, which is thin walled and papillose.

Economically important plant in this genus is Cyphomandra betacea. Other important related species are Cyphomandra casana (Casana), C. craccifolia (Mountain tomato) and C. fragrans (Guava tamarillo). It has got distant affinity with Lycopersicon esculentum (Tomato), Physalis ixocarpa (Tomatillo), P. peruviana (Cape gooseberry), Solanum muricatum (Pepino Dulce) and S. sessiliflorum (Cocona).

Introduction

Wet ashing is suitable for the determination of Ca, Cu, Fe, Mg, Mn, K, Na, Se and Zn in biological samples and may be applicable to the determination of other elements as well.

The organic matter of the sample is oxidized with concentrated nitric acid and perchloric acids. The acids are partially removed by volatilization and the solube mineral constituents remain dissolved in nitric acid. Any silica present is dehydrated and made insoluble.

Starter cultures were unknown until 1878, when Lister isolated pure cultures of the lactic acid bacteria responsible for milk acidification. In the 1980s, improvements to standardization and ripening of butter were made by introducing pure starter cultures. During the period 1910-20, Orla-Jensen, von Freudenreich, Sherman, Hammer and other dairy microbiologists prepared pure cultures for fermented milks. Commercial production and use of starter cultures grew rapidly and was widespread at the beginning of the 20^th century.

Dairy starters are the ‘heart’ of fermented milk products, the most crucial component in the manufacture of high-quality fermented milks. The cultures are harmless food-grade microorganisms, active bacteria intentionally grown in milk or whey or other formulated media which impart desirable and predictable flavour and texture to fermented dairy products.

The dairy microorganisms employed in milk fermentation are single-strain or multiple-strain cultures of lactic acid bacteria, producing different types of fermented milk products. Usually, one or two strains dominate the milk environment. Individual strains can be selected in advance for their resistance to both bacteriophages and antibiotics. Mixed starter cultures are used to ensure that fermentation will continue after a bacteriophage attack. Bacteriophages are highly strain-specific, and if the dominant strain in a mixed-strain starter culture succumbs to an attack, the phage-resistant mutant or the next dominant culture maintains a satisfactory rate of lactic acid production.

The ultrasonography is a technique which uses sound waves of very high frequency to scan the various organs of the body. The ultrasound waves of 2-10 mHz frequency are used in veterinary practice. A quartz crystal when stimulated by short pulse current ultrasound waves are emitted. The ultrasound waves emitted are directed towards a specific target organ are reflected back as echoes. The echoes are received by the same quartz crystal and are processed in the electronic circuit and finally displayed as image on the monitor.

Introduction

India has a long tradition of agroforestry which is widely practiced in all ecological and geographical regions of the country. Traditional agroforestry systems are broadly based on indigenous knowledge and the species are selected as a part of the cultural patterns of the community. The farmers and land owners in different parts of the country integrate a variety of woody perennials in the crop and livestock production systems depending upon the agro-climatic conditions and local requirements.

ALL MATTER IS IN MOTION

Everything moves:

In the atom electrons rotate around the nucleus

In gases, liquids and even solids molecules move away from other molecules

An accumulation of matter (i.e., a baseball) can move as a unit

The average velocity of movement is the distance travelled divided by the time

Bodies in motion have energy; the faster the velocity the more energy

1.1. National Agriculture Scenario

Agriculture is the most important sector of Indian Economy, contributes 23 per cent of national GDP, accounts for 11 per cent of exports, and 50 per cent of billion depends on it. Interestingly India feeds 16 per cent of population with 2.4 per cent of global land.

In the last five decades, there has been a steady and spectacular transformation of Indian agriculture from the food deficit to food sufficient status. Diffusion and adoption of modern technologies, high yielding varieties, dedicated efforts of farmers, extension personnel and scientists and also programmatic support of central and state governments have all contributed significantly from 50 million tonnes in 1950-51 to land mark achievement of 230.67 million tonnes of food production in 2008-09.

Development of Agriculture in the World and in India

Agricultural ecosystems will increasingly be called on to deliver food and fiber for a demanding and expanding global population. Until recently, increased production relied on expansion of the amount of land under cultivation and irrigation. Since World War II, production advances have relied on genetics and plant breeding, advances in fertilizer and pesticide use and improved cultural management (Matson et al., 1997). Since 1950, agriculture worldwide has expanded cereal production by an average of 2% per annum while population has increased by 1.9% per year (Borlaug and Dowswell, 1994).

Modern science-based agriculture had its beginnings in the late 19^th century with improved traction and tillage equipments. However, it was not until after World War II that the research findings that led to the modern-day productive systems in the United States and later in European and other developed countries. The expansion was directly related to the great demand for food to support the Allied war effort. Knowledge bases developed in plant genetics, physiology and pathology, along with a ten-fold increase in fertilizer use, advances in seed technology, weed control, irrigation and cultural methods allowed the development of the systems that dominate agriculture in many of the countries today. Corn or maize responded dramatically to the advances in production technology. Maize yield in the United States has increased more than 300 per cent over the past 50 years and continues to rise. Maize production technology has been delivered worldwide (Borlaug and Dowswell, 1994).

Abstract

The landslide is a disaster which causes rampant loss to life, property and ecosystems. With increased awareness and technological development, the number of monitoring stations near hazardous regions have increased. To give warning prior to the occurrence of a landslide, the soil/rock mechanics of the underlying bed needs to be studied and understood. This paper examines the current literature and elucidates some features of state-of- the-art landslide monitoring systems.

Keywords: Field based sensors, Wireless sensor network, Landslide monitoring

INTRODUCTION

Advancements in technology have helped us to understand nature better than before, yet the geotechnical parameters causing landslides could not be quantified accurately. The efforts taken in predicting landslides are clearly moving towards this objective and this can be seen by the number of monitoring stations that have been setup in landslide prone areas around the world. The data that is obtained at each location is important in understanding landslides. Each location is unique in terms of soil properties, groundwater, inclination of the slope and weather conditions and consequently, each deployment is unique.

The paper narrates the instrumentation based forewarning systems functioning around the world. The paper discusses these aspects hierarchically viz; Landslide prone areas in India, geotechnical instrumentations and their merits, influence of rainfall on landslides, correlation between rainfall and pore pressure, the relevance of different systems for different scenarios etc.

4.1 Introduction

The purpose of processing the food is to make it safe and healthy for human consumption. The term food processing refers technologically anything, which transforms raw ingredients into consumer ready products, with the aim of stabilizing food products by preventing or reducing deteriorative changes in quality. The objective of food manufacturers is to develop, modify and employ those processing technologies that retain or create desirable sensory qualities in food and eliminate or reduce undesirable changes due to processing.

The purpose of food processing is to increase the shelf life of food before spoiling (preservation); to remove, destroy or inhibit pathogens and toxins (food safety); to change flavor, texture, aroma, color or form (variety); to reduce preparation times and make food more portable (convenience); to restore and/or raise nutrient levels in food (nutrition).The various food processing methods used extensively in food industry include physical (high temperature, freezing, chilling, dehydration, packaging), chemical (control of storage gases, reduction of water activity, pH, addition of chemical additives or spices) preservation methods.

Traditionally, food preservation has been associated with thermal treatments alone or in combination with biochemical or chemical methods. For example, the thermal processing of milk is done various thermal treatments viz. at 63^oC for 30 min for low temperature long time (LTLT), 72^oC for 15 seconds for high temperature short time (HTST) pasteurisations and up to 140^oC for a few seconds for ultra high temperature (UHT) treatment. However, such thermal treatments effectively reduce level of microorganisms but in long-term preservation, it may lead to losses of desired organoleptic attributes and destruction of temperature liable nutrients and vitamins. The limitations involved with thermal processing has been overcome by employing chemical preservation, cool chain management and process hygiene in the formulation and production of food products.

At times a pesticide application fails to reduce the levels of a pest. Usually, the farmer blames either the pesticide for this or he thinks that the pests have developed resistance. Though, the usual causes of poor results with an application of a genuine pesticide from a reputable source are:

Abtract: Dahlia, tuberous flowering plant, is valued for potted flowering and garden crop worldwide. The genus contains ~85 species native to Mexico, central America and Columbia. Numerous phenotypes (star/ anemone/ paeony/ decorative/ pompon/ cactus/ water lily flowered) and cultivars (giant/ large/ small/ miniature/ ball/ pompon/ mignon single) are available on world market. Cultivated dahlias are allotetraploids with great diversity in flower colour/ forms. Limited genetic information and trait heritability has been established for this crop. Precise elucidation of the genes involved in the flavonoid biosynthesis pathway has enabled in the creation of new flower colours or modification of pigment production and expression discussed. Research succeeded in mutation breeding and interspecific hybridization and colourful dahlia varieties have been developed by individual enthusiasts, nurserymen and flower breeders. Complicated genetics, heterozygosity often pose significant challenges to breeders. Future crop ideotypes are proposed to continue transformation of this important crop during the next millennium.
