1. INTRODUCTION

There is increasing recognition that information and knowledge are now at the heart of socio-economic development. Information and Communication Technology (ICT) and broadband are enabling tools and infrastructures for accessing, developing, using and sharing information and knowledge. Accordingly, Irish Government policy has focused on promoting the adoption and use of ICT in the home, in education and in the workplace.

There have been significant increases in levels of engagement with ICT in Ireland in recent years. Almost two-thirds of all adults now have access to the internet, compared with only 1 in 20 in 1996, while four out of every five adults own a mobile phone. This chapter critiques the level of adoption of ICTs among the farming community and compares this with levels of adoption by the general population. It analyses the use of ICTs by the government and by public and private extension agencies in Ireland and identifies constraints to their adoption.

The Ministry of Agriculture has been among the most enthusiastic supporters of the Government of Ireland’s policy by promoting the adoption and use of ICTs among its clients. It sought to facilitate easier transmission of information to clients, to minimise the collection of new data by using existing electronic information and to integrate with clients’ own systems. These projects are described in this chapter.

The use of ICTs by the public extension system is also critiqued; it has been innovative in using ICTs to disseminate information to its clients and the use of mobile telephony has been particularly effective. Internet based services to deliver online training and advisory information have also been developed and are critiqued.

Abstract

Kaliasaur landslide located 18km from Srinagar on the NH-58 in Uttrakhand Himalayas has been repeatedly sliding for the last over 5 – 6 decades totally paralyzing the transport operations in the region and causing beeline of issues not only for the people living in the hilly state but also the tourists and the pilgrims. The study of Geosystems & geodynamics, large scale micro zonation and geotechnical studies using RMR and SMR techniques show that the slide is located in high hazard zone and follow the pattern of wedge and planar failures with vulnerable zone of factor of safety. The toe erosion by the acutely turning Alaknanda river and the mitigation measures in the form of slope disturbance in the upslope part rather protecting slide, has been responsible for the recurring slides. The study further revealed that excessive rainfall is also a triggering parameter and the crown part is widening. On the basis of the studies, mitigation measures have also been brought out.

Keywords: Kaliasaur landslides, Micro LSV zonation, Factors of landslides, Mitigation.

6.1 Introduction

Consumer demand, regulatory guidelines and economic power of the consumer as well as ascertained profitability stimulated the need of novel food processing techniques. The concept of “fresh”, “natural”, or “organic” food also led to the development of environmentally sound and resource efficient food processing technologies. Thermal processes have been used for food preservation since a long time. These are not very energy efficient and can change the phase of food from fresh to cooked as well as it can alter the nutritional and sensory qualities. Thus, the quest for energy conservation by the manufacturers to reduce carbon footprint of the processes involved in food processing and preservation as well as to fulfill consumers’ requirement for fresh-like quality food have given rise to the development of innovative non-thermal food processing technologies i.e. ionizing radiation, high-intensity light pulses, high isobaric pressure, electric or oscillating magnetic fields, as well as pulsed electric fields (PEF).

Application of electric energy in food processing started in the early 1900s. In the beginning, electrical pasteurization inactivated microorganisms by increasing the temperature of samples by means of an electrical resistance (ohmic heating). Milk was the first electrically pasteurized product. In the late 1940s, electric fields were used to increase the permeability of fruits to facilitate the subsequent extraction of juices. The PEF technology as a non-thermal process is very effective for inactivation of microorganisms, increasing the pressing efficiency, enhancing the juice extraction, and for intensification of the food dehydration and drying process. The main effect of PEF technology is based on the phenomena that biological membranes are punctured under the influence of external electrical impulses. This process is often referred as non-thermal, since the structural damage to membranes is implemented at very low temperature compared to the conventional heating process. The PEF process is considered to be energy efficient because the electric energy is released in short pulses, thus total energy requirement is much lower than other continuous preservation technologies. The microbial inactivation can be achieved at ambient or moderately elevated temperatures by the application of short-bursts of high intensity electric fields to liquid foods flowing between two electrodes or to semi-solid/ solid food between some specialized electrode and treatment systems. Due to chemical/physical properties and presence of electrical charge, the liquid foods (e.g. milk or fruit juices) had different conductivity, which results in variable flux of electrical current through the food systems.

Pesticides can cause three types of harmful effects – Acute, Delayed and Allergic.

Acute effects: Are those that occur immediately after the exposure, within minutes or hours.

Abstract: Pelargonium (syn. Geranium), has become mainstay in temperate landscapes because of its ease of production and cultivation, long lasting bloom, range of plant habits and diversity of uses (perfumery, cosmetic, pharmaceutical and food industries). Confusion exists about nomenclature and taxonomic revision has attempted. Pelargoniums are popular seed and vegetatively propagated bedding and pot plants with numerous phenotypes (Fish type, Ivy leaved, Regal, Angels, Fancy leaves, Scented, Oak leaf) and cultivars (Double/ Bar/ Centre/ Ring/ Vein/ Picotee pattern/ Tulip/ Carnation/ Phlox/ Birds egg flowered) available on the world market. Their continued popularity has warranted extensive breeding and development of novel phenotypes particularly trailing growth habit, reduced plant size, compact form, manipulation of flowers (size, number, coloration, longevity, timing) and disease resistant cultivars. Increasing knowledge of the inheritance of traits, molecular genetic techniques and biotechnological applications are valuable tools aiding modern pelargonium breeders. The need of new cultivars remains strong as divergence among pelargonium market types increases, production system becomes more specialized and new market develops.

Waste is not actually waste but is the by-product of various activities of human life. The unclean handling of these wastes creates problem for public health departments and local bodies. The classification of waste depends on the agencies that classify these wastes according to the area of interest and method of disposal viz. medical field, agricultural field, local bodies, industries etc.

In the present paper, the emphasis is given to the classification based on agricultural activities which includes a) Agricultural marketing waste b) Meat and fish marketing waste.

Various types of cropping systems are practiced in a farm or region. They should be evaluated to find out their stability and relative advantages in yield. Again, comparisons may be made with reference to land use efficiency, biological potential and economics. Following are the important indices for assessment of competition and yield advantage:

1. Relative yield total (RYT): The oldest establishment measure of the yield advantage of crop mixtures is the Relative Yield Total. The RYT index was designed as a measure of the extent to which various crop components shared common resources, rather than as a direct measure of yield advantage.

Powdery Mildew

Erysiphe polygoni

Economic Importance

• Powdery mildew can be a serious disease of peas grown in India.
• It appears in epidemic form in the plains almost every year when the pods are formed in January-February.
• Since the disease occurs more frequently and covers a large host surface, it proves much more destructive than the downy mildew disease of the same crop.
• It is worst in dry weather as against the downy mildew, which flourishes in moist weather.
• Severe infections can reduce yield by 10–20%.
• Severe pod infection can lead to poor seed quality.

Abstract

Mentheae, one of the largest tribes of subfamily Nepetoideae of family Lamiaceae is represented by five genera (Mentha, Nepeta, Origanum, Salvia and Thymus) in Jammu and Udhampur districts (Jammu division). Frequent surveys made of these districts to generate ethnobotanical data revealed the existence of Mentha arvensis L., M. longifolia (L.) L., M. piperita L., M. spicata L., Nepeta cataria L., Origanum vulgare L., Salvia splendens Sellow ex Schult and Thymus serpyllum L. While the enlisted Mentha species are represented more or less equally in the two districts, N. cataria, O. vulgare, S. splendens and T. serpyllum are mainly adapted to temperate regions of Udhampur. The frequent interactions with the locals indicated that except M. spicata whose leaves are used for seasoning dishes or preparing refreshing drinks and those of O. vulgare which find utility in making herbal tea, others are largely used for therapeutic purposes. Amongst these species, maximum use value was noted for M. longifolia (0.81) followed by that for M. arvensis (0.69). So far as agreement among the informants regarding the usage of a species for curing a particular disease is concerned, it came out to be maximum for both M. longifolia and M. arvensis for treatment of respiratory (Fic=0.93) and gastrointestinal problems (Fic=0.93). In our study, most of the informants have predisposition towards using M. longifolia for treating respiratory disorders particularly cough and cold. For this species, fidelity level was found to be maximum equal to 33.33%. This indicates that M. longifolia carries great potential for using in new herbal formulations. Finding of lesser use value for O. vulgare (0.21) and T. serpyllum (0.30), reportedly having many medicinal important components, is a matter of concern. The probable reasons underlying quite less usage of these taxa have also been discussed in this communication along with the future prospects of cultivating these.

Principle: Acetone is used for extraction the most nonionic pesticide residue, and residue are partitioned from acetone to dichloromethane/hexane phase. After removing traces dichloromethane, final extract is made up with acetone. This extract can be determined by GC with selective detectors FPD-P/NPD without cleanup. Further for organochlorine and synthetic pyrethroids extract should be cleaned up using florisil column. And for determination organophosphate extract should undergo to charcoal-celite cleanup.

Enumeration of microbial flora present in soil is done by dilution plating technique. The technique is based on the fact of diluting the source inoculums to the extent that after plating the known volume of inoculums on appropriate media, the colonies will appear in countable range and each colony will be assumed to have been derived from a single cell/colony forming unit. Three numerically dominant groups of soil microbes are bacteria, actinobacteria and fungi. The most commonly used culture media for their enumeration include

Nutrient Agar-for heterotrophic bacteria,

Actinomycetes isolation Agar or Kenknight and Munaier’s agar for actinobacteria

Martin’s Rose Bengal Agar for fungi.

Life cycle of nematode has six stages. The egg stage, first stage juvenile (J₁), second stage juvenile (J₂), third stage juvenile (J₃), fourth stage juvenile (J₄) and the adult stage.

The first four stages are the immature stages and are known as juvenile stages. The female lays eggs in soil or in plant tissues, singly or in groups as egg mass that hatch out into juveniles which are almost similar to adults appearance. The first moult occurs within the egg shell and the second stage juvenile comes out by rupturing the egg shells as J₂. In case of Xiphinema index, the juveniles are reported to emerge from the egg before the first moult. The juvenile cuticle is shed after each moult.

The egg

The nematode eggs are oval in shape. The eggs are covered by three membranes, the external protein layer which is the secretion of uterus wall, the middle chitinous layer or the true shell secreted by egg itself and the inner lipid layer (vitelline layer). The chitin content in the egg shell vary in different species of nematodes.

Ornamental plants that are adapted to an aquatic environment are commonly grown in water gardens and pools. They include those that are entirely submerged or floaters that are free living in the surface water or having roots anchored firmly in the ground beneath and marginal plants that thrive along the edges of water bodies and in shallow water. Spectacular flowering plants like the lotuses and water lilies to plants like the tape grass that are entirely submerged and grass like are grown in natural or structured fresh water habitats throughout the world. Many of these are also inhabitants of aquaria.

Some of the popularly grown water garden plants are listed below:

Acorus calamus

Araceae

Sweet Flag, Vayambu

Plants are rhizomatous herbs adapted to low lying and wet situations. The leaves are closely spaced, distichously arranged and resembling a fan, leathery, dark green, smooth and shiny. The inflorescence is a spadix that emerges from the middle of the terminal leaf. Plants are valued medicinally for their aromatic rhizomes and are also commonly grown as marginals of water gardens.

Nutrients

The nutrients are chemical elements which are absorbed by the plants in more or less quantity to transform light energy into chemical energy and to keep up plant metabolism for the synthesis of organic materials. These materials constitute among other things, foods for humans and animals and a range of raw materials for various industrial uses. Feeding of plants with nutrients is termed as nutrition. Successful growth and production of the plants in general requires a proper supply of the 17 elements. These elements are regarded as essential to life in higher plants.

6.4.1. Function

The brake is used to stop or slow down the motion of a tractor. It is mounted on the driving axle and operated by two independent pedals. Each pedal can be operated independently to assist turning of the tractor during field work or both the pedals can be locked together.

6.4.2. Principle of operation

The brake works on the principle of friction. When a moving element is brought into contact with a stationary element, the motion of the moving element is affected. This is due to frictional force which acts in the opposite direction of the motion and converts the kinetic energy into heat energy.

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.

Kiwifruit (often shortened to kiwi outside Australia and New Zealand), or Chinese gooseberry, is the edible berry of several species of woody vines in the genus Actinidia (Lucas, 2003 and Stirk, 2005). The most common cultivar group of kiwifruit (Actinidia deliciosa ‘Hayward’) is oval, about the size of a large hen’s egg: 5–8 cm (2.0–3.1 in) in length and 4.5–5.5 cm (1.8–2.2 in) in diameter. In 2017, China produced 50% of the world total of kiwifruit.

Kiwi is among the very few recent introductions which have surpassed in popularity due to its tremendous commercial potential in the Sub Himalayan region of India. In fact, no other fruit has attracted so much attention in such a short period in history of commercial fruit production since 1960s. In India, Kiwi was first planted in the Lal Bagh Garden (1960) at Bangalore as an ornamental tree where bud bursting didn’t take place. Later on for cultivation purpose it was planted at IARI, Regional Station, Shimla (H.P.)
