Introduction

Spatial data is different from a non-spatial data in the sense that it always has a spatial reference system which is nothing but a pair of coordinate values and a system of reference for these coordinates. For example, the locations of benchmark soil series of India can be defined as pairs of longitude and latitude in decimal degree values with respect to the prime meridian at Greenwich and zero latitude at the equator. The World Geodetic System (WGS84) is a frequently used system of reference on the Earth. The different types of spatial data are: (i) point, which is a single point location, such as a GPS reading or a geocoded address (ii) line, which is defined as a set of ordered points, connected by straight line segments (iii) polygon, an area, marked by one or more enclosing lines, possibly containing holes and (iv) grid, a collection of points or rectangular cells, organised in a regular lattice. Among the above said spatial data, the first three are vector data models and represent entities as exactly as possible, while the fourth data model is a raster data model, representing continuous surfaces by using a regular tessellation. In this chapter, we discuss how a spatial data can be handled in R. There are several packages available in R in which spatial data analysis can be handled e.g. sp, rgdal, raster etc. All the contributed packages for spatial data analysis in R address two broad areas: moving spatial data into and out of R, and analysing spatial data in R. In the following section, the sp package for spatial data handling is briefly discussed.

Floriculture is the most important aspect of urban agriculture, which fulfils the need for beautification, recreation, entertainment and income earning. In broader sense, it includes growing flowering and ornamental plants in gardens, rooftops and terraces. Floriculture comprises of house plants, flowering plants, pot plants, cut flowers and decorative foliage. It also deals with cultivation of cacti, orchids, succulents, bonsai, ferns and plants grown in landscape gardening.

Role of flowers in our life

• It is a unique gift of nature to relax human mind
• The fragrance and beauty of flowers bring joy and happiness
• Flowers are used as a symbol of grace and sophistication
• Flowers are used in religious rituals for offering during worship

Enzymes are organic catalysts produced by living organisms. They make possible biochemical reactions. Hence they are called biocatalysts. They are mostly a specialized class of proteins. However, there are some non-protein enzymes like ribozymes, which are RNAses. Enzymes speed up reactions at ambient temperatures. This is in contrast to chemical reactions like saponification of lipids which take place when lipids are boiled for a few hours with concentrated alkali.  Enzymes, namely, lipases, hydrolyze lipids at body temperatures in minutes. They are superior to chemical catalysts by a factor of 107 to 1014 .  An enzyme may be a simple protein or a complex protein. They are produced by cells and are mostly globular proteins. Each cell contains an estimated 3000 different enzymes.

Fruit trees can be planted in the backyard or any open space near the house. In absence of backyard area, fruit trees can also be grown on the rooftop by planting in polythene bag, plastic container, cemented pot, etc. Growing fruits like papaya, banana, lemon, mango, pineapple, coconut, pomegranate, etc. in the premises of house can fulfil the family requirement of fruits. It will help to get fresh fruits from own garden, which are free from any chemical or pesticide. There is a different satisfaction in plucking of fruits grown by own effect.

Mango

Mango (Mangifera indica) is one of the prominent fruit crops of India. It has delicious taste and excellent flavour. Mango fruit is utilized at all the stages of its development. Raw fruits are used for preparation of pickle, chutney and juice. The ripe fruits are consumed directly and are used for preparation of several products like squash, syrup, jam and jelly. Ripe mango contains about 0.6 per cent protein, 0.1 per cent fat, 11.8 per cent carbohydrate, 0.3 per cent minerals and 1.1 per cent fibre. 

Introduction

Potato is mostly considered as a vegetable crop in India, whereas it is a staple food crop in Europe, Canada, Australia, U.S.A, South America, Russia, Asia and other countries. In India, it is cultivated extensively in the hilly tracts during December-March or March-June and in the plains during September-January, as it requires cool and moist climate condition. As per FAOSTAT (2015), the potato production in India during 2013 was 45.34 mt from 1.99 mha area with a productivity of 22.76 t/ha. There are several varieties of potato grown in India and many diseases, some of which cause considerable damage to the crop. Potato crop can be affected by diseases caused by fungi, bacteria, virus, viroids and others by non-parasitic.

Late Blight

Economic Importance: Late blight is one of the most devastating diseases of potato throughout the world. It is recorded in area with frequent cool and moist weather. The disease is believed to have been introduced into Europe from South and Central America and spread to other countries which include the East Coast of Canada, Western Europe, Central and Southern China, South Eastern Brazil and the tropical highland. It created history by causing a famine in Ireland known as Irish Famine during 1845-46 resulting in death of many people due to starvation, dysentery and typhus spread among the farmers and subsequent migration of people from Europe especially from Ireland. Late blight has the tremendous potential to cause upto 70% reduction in the yield in a susceptible cultivar. Region wise economic importance of late blight shows that the disease takes highest toll of potato in Sub-Saharan Africa (44% crop losses) followed by Latin America (36%), Caribbean (36%), South-East Asia (35%), South-West Asia (19%)

ABSTRACT

Dysoxylum binectariferum (Roxb.) Hook. is an evergreen tree, indigenous to India and widely distributed in different parts of India. Primarily, this plant is used in the timber market for the preparation of furniture and other wooden goods. Apart from utility in timber market, it has tremendous medicinal properties because of its unique secondary metabolites. Its hydroalcoholic extracts possess a wide range of pharmacological activities including immunomodulatory, anti-inflammatory, anti-cancer, anti-leishmanial, etc. The chromone alkaloid rohitukine, the major constituent of the plant, possess anti-fertility, anti-leishmanial, anti-adipogenic, anti-ulcerogenic, anti-cancer and immunomodulatory activities. The most extensively studied and advanced therapeutic property of this chromone alkaloid is its cyclin-dependent kinase inhibition activity, which has a direct link with its anti-cancer effect. Inspired by this natural product, two clinical candidates (flavopiridol and riviciclib) are discovered and studied in human cancer patients for treating various types of cancer. Another preclinical lead IIIM-290, which is directly derived from rohitukine via synthetic modification, has demonstrated promising oral efficacy in animal models of various cancer types. The high-value medicinal applications of this plant have necessitated the need of bringing this tree under captive cultivation. The present chapter discusses the biology pharmacological and secondary metabolites present in Dysoxylum binectariferum. The preclinical and clinical leads derived or inspired from rohitukine are also discussed in this communication.

Tomato (Lycopersicon esculentum Mill.) is one of the most important vegetable crop and is known as protective food due to its wide spread production and special nutritive value. Tomato is referred to be native of tropical America. In the 16^th century, it got spread from America to other parts of the world and became popular in India within the last six decades. It is known as world’s largest vegetable crop after potato and sweet potato. The overall world production of tomato is 1,180,000 tons with a productivity of 65 t/ha. Contribution of USA in tomato production is 13.2 million metric tons to the total world production (FAOSTAT). USA ranks third in position in the total world production of tomato after China and India (FAOSTAT). India produces 22,337MT of tomato from 801ha area.

Fungal Diseases

Fusarium Wilt

Economic Importance

Fusarium wilt caused by Fusarium oxysporum being so widespread, turns out to be a significant problem in many crops. It is one of the most widespread and damaging diseases of tomato wherever tomatoes are grown intensively. The pathogen also causes damage to many other crops likepotato, and pepper of the family Solanaceae. Yield losses of effected crops can goup to 45% in tomato in India.

Cape gooseberry (Physalis peruviana L.)

Cape gooseberry, scientifically known as Physalis peruviana L. (Physalis edulis Sims) belongs to family Solanaceae. Fruits are enclosed inside a bladder- like husk which turns papery when mature making all seeds inside visible. There are more than 70 species under the genus Physalis. Out of these species only few of them are of economic value. Cape gooseberry is most widely known among these species as it bears superior fruit in comparison to other species. The fruits are good in taste and a good source of minerals and vitamin such as vitamin B complex, vitamin C and pro-vitamin A, rich in pectin.

Species diversity

Cape goosberry is also known by different names in Latin America: capuli, aguaymanto, tomate sylvestre, or uchuba, in Bolivia; uvillain, in Peru; capuli or motojobobo embolsado, in Colombia; topotopo, chuchuva, in Ecuador; uchuva, vejigón or guchavo in Venezuela; capuli, amor en bolsa, or bolsa de amor, in Chile; cereza del Peru in Mexico; teparee, tiparee, makowi, etc., in India. Physalis pruinose L. commonly known as strawberry tomato, husk tomato or ground cherry is also grown for its small yellow fruits. In mild-temperature climates, the fruit is used to make sauce, pies, and preserves. Unripe druits are toxic. In Australia, the plant is thought to have caused illness and death in cattle.

4.1 Introduction

A farm pond is basically small scale water harvesting and water recycling structure. It harvests water mainly in the rainy season when there is abundant rainfall producing sufficient runoff and the harvested water may be used for single or multiple cropping. When there is deficient supply of water to the crops it may supplement as supplemental irrigation. The leftover water in the pond can be used for growing another crop in winter when there is no or less rainfall. Ij addition, the stored water in the pond can be used for domestic and other uses and rearing fish. Thus it serves as viable medium for integrated farming system in rainfed farming ecosystem. Before designing a pond in a given location, it is very important to estimate the total quantity of water supply to the pond. The two main sources of water supply to pond are (i) in situ rainfall and (ii) runoff (some times called as discharge) generated from the catchment and conveyed to the pond. Some times there is groundwater contribution to the pond when the pond is unlined and the underlying groundwater table with reference to the ground level is at lower elevation than the depth of water in the pond such that there is a hydraulic gradient in the direction of underlying groundwater level to the water level in the pond.

Abstract: Viola or garden pansy, commonly known as sweet violet or king of annuals, are widely cultivated worldwide for landscape planting, garden design and container gardening. Today, numerous OP varieties, F₁ hybrids (Europa, Toto, Wasa), F₂ strains, series (Waterford, heat tolerant S series) and cultivars introduced by seed companies are available on the world market. Pansy breeding efforts have been focused on F₁ hybrid seed production, heat tolerance, flower colour, flower size and form, double flowers, earliness, disease resistance, floriferous nature and interspecific hybridization. Increasing knowledge of the inheritance of traits and molecular genetics techniques are valuable tools aiding modern pansy breeders. Research is needed to exploit heterosis for productivity and gene transformation to create new genetic variability.

This chapter focuses on the design and performance evaluation of pyrolyzers, which are key components in producing biochar, biofuels, and other valuable products through the pyrolysis process. Pyrolyzer play a crucial role in converting biomass feedstock into desired end products, and their design greatly influences process efficiency and product quality. The chapter discusses various aspects of pyrolyzer design, including reactor types, operating conditions, heating methods, feedstock characteristics, and process optimization. It also explores performance evaluation methods to assess pyrolyzer efficiency, product yield, biochar quality, and energy consumption. The information presented in this chapter aims to provide researchers, engineers, and practitioners with valuable insights into pyrolyzer design and performance evaluation for efficient and sustainable biomass conversion.

Pineapple Ananas comosus (Linn.) Merr. (Family – Bromeliaceae) is a tropical plant with edible fruit comprising of coalesced and the most economically important plant. The pineapple is native of southern Brazil and its wild relatives present at Paraguay. It was introduced in India by the Portuguese. Before arrival of Columbus the Indians deported it to West Indies. The Spanish introduced pineapple in Philippines. It was also introduced in Hawaii during early 16^th Century. The fruit reached in England during 1660 and began to grown in greenhouses in around 1720.

Abstract
Pesticides, which are extensively employed in agriculture and pest management, pose serious dangers to the environment and public health because they frequently enter aquatic ecosystems through runoff, leaching, and inappropriate disposal. Acute and chronic toxicity in aquatic creatures caused by pesticide poisoning in water bodies can disturb ecosystem services and biodiversity. As sentinel species, fish have immune-toxic consequences, such as impaired immune function and increased vulnerability to illness. Aquatic animals and human health are at risk due to the bioaccumulation of pesticides in fish tissues and their subsequent biomagnification in the food chain. In order to control pesticide exposure and guarantee safety, important parameters such as Maximum Residual Limits (MRLs) and Acceptable Daily Intake (ADI) are essential. In order to control pesticide, use and lessen its negative effects, government regulations and international standards are essential. In order to protect aquatic ecosystems and human health, future research should give priority to environmentally suitable pesticide substitutes and strong regulatory frameworks.
Keywords: Pesticides, Toxicity, Aquatic Environment, Bioaccumulation and Biomagnification.

Introduction

Recent advances in bioinformatics such as microarray analysis are bringing about a revolution in our understanding of the molecular mechanisms underlying normal and dysfunctional biological processes. With the help of microarray technologies, biologists are currently capable of observing the abundance of transcripts from tens of thousands genes in biological samples, enabling the exploration of the dynamics of transcription and interaction between genes on a genome-wide scale. With the accumulation of gene expression dataset, the challenging task of all microarray experiments is how to extract meaningful and trustworthy information out of thousands of genes that do not contribute in the designed experiments. To achieve this goal, many rigorous mathematical tools and computational software were introduced to the field, like statistical techniques for data normalization, clustering algorithms, class prediction methods, ANOVA, and gene-gene interaction studies. Microarray technology has been used widely in various areas of agriculture and allied field. Application of statistics in microarray is limited particularly in experiments involving fishes. In this chapter it is attempted to present various statistical methods applied to accessory microarray experiments with illustrated example of fish microarray data.

Alstroemeria belongs to the family Alstromeriaceae. Alstroemeria flowers third in terms of popularity and foreign exchange earnings in Kenya after roses and statice. Alstroemeria is named after a Swedish botanist “Baron Klas von Alstroemer”. The popularity of this flower is still growing in the global perspective. It is one of the quickest growing flowers with varying colours like purple, lavender, salmon, red, pink, white, orange, yellow and bicolour. It is grown for cut flowers but is also popular as a potted plant. It is grown in the higher ranges of the Western Ghats, Himachal Pradesh, Jammu & Kashmir and Karnataka in India.

1.1 General

The term “biomass” generally refers to renewable organic matter generated by plants through photosynthesis. Materials having organic combustible matter is also referred under biomass.Biomass is an important fuel source in our overall energy scenario. Biomass is produced through chemical storage of solar energy in plants and other organic matter as a result of photosynthesis. During this process conversion of solar energy in sugar and starch, which are energy rich compounds takes place. The chemical reaction of photosynthesis can be written as:

6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂ + 636kcal

It indicates that the storage of 636 kcal is associated with the transfer of 72 gm carbon into organic matter. Biomass can be directly utilized as fuel or can be converted through different routes into useful forms of fuel. In fact, biomass is a source of five useful agents, which start with ‘F’ like food, fodder, fuel, fiber and fertilizer. Further, biomass has many advantages like.

(1) It is widely available

(2) Its technology for production and conversion is well understood.

(3) It is suitable for small or large applications

(4) Its production and utilisation requires only low light intensity and low temperature (5 to 35°C)

(5) It incorporates advantage of storage and transportation

(6) Comparatively, it is associated with low or negligible pollution.
