Objectives

1. To know the layout methods.
2. To know the planting techniques of various spices and condiments.

Layout: Systematic arrangements of plants

Some spices and condiments just like clove, cardamom is perennial in nature. Being perennial in nature any mistake committed during initial year, on the part of planning, is hard to rectify. Hence, all the factors having bearing on growth, production and overall performance of the plant should be given top priority.

Systems of planting

1. Square system: In this system row to row distance and plant to plant distance is kept similar.

The primary function of cardiovascular system is to maintain blood circulation so that normal exchange of fluid, electrolyte, oxygen, carbon dioxide, nutrient
and excretory and secretory end products can take place between tissue and blood. Failure of circulation to any degree interferes with the transport and
exchange mechanism.

This is one of the most serious difficulties in mango farming since it makes mango agriculture less rewarding for farmers. In one year (a year) and very little or no harvest next year, mango trees appear to bear huge crops (off year). This bieniality is therefore also present in normal ranges (Singh, 1990). 

Peach (Prunus persica L. Batsch) is a small to medium sized open topped branches, medium stocky, spreading as well as upright growth habit. The Peach is the native of (china, currently around 3000 peach cultivars are available in the world over (Faust and Timon, 1995).

Important Points to Remember

• The term Biochemistry (biosG = life) was first introduced by a German chemist Carl Neuberg in 1903. Biochemistry may be defined as a science concerned with the chemical nature and chemical behavior of the living matter.
• Major organic molecules present in the living beings are: carbohydrates, proteins (of course, including enzymes), lipids and nucleic acids.
• Carbohydrates are the most abundant organic molecules in nature. They are primarily composed of the elements carbon, hydrogen and oxygen.
• The name carbohydrate literally means ‘hydrates of carbon’. The simplest carbohydrates are the monosaccharides that have the general formula (CH2O)n where n is 3 or more.
• Carbohydrates may be defined as polyhydroxyaldehydes or ketones or compounds which produce them on hydrolysis. The term ‘sugar’ is applied to carbohydrates soluble in water and sweet to taste.

Observation recording: To record the response of various tree species to the light, fire, drought, frost and wind, frequent visits of the forest areas which are affected by fire, drought and frost should be conducted. Studies relevant to light requirement in various growth stages of tree and ability to stand against various intensities wind are very lengthy that requires long time periodic studies.

Vegetables are the largest important constituent of our daily diet as well as high value cash crops for small, marginal and large scale growers. These are rich in proteins, vitamins, minerals and dietary fibre which are essential for our normal body functions, prevention of malnutrition and deficiency diseases. Vegetables also play key role in neutralizing the acids produced during digestion of fatty foods and also provide valuable roughages which help in movement of food in intestine.

Abstract

Sequence alignment is the positioning of DNA, RNA, or protein sequences with each other to identify the regions of identity, which may be the result of functional, structural, or evolutionary relationships between the sequences. Therefore, sequence alignment is the process of aligning two sequences to achieve the maximum levels of identity and conservation. This chapter deals with the basic concept of sequence alignment and the tools associated with multiple sequence alignment. Further, it describes various matrices used in sequence alignment.

Growth of urban population has become a challenge throughout the world. Presently, many of the cities are featured with high rising buildings, rush of vehicular traffic and networking of industrial establishments. The urban ecological footprints are increasing day-by-day resulting in unfavourable living conditions. The cities require vast area of land to sustain the population for requirement of food, clothing and other requirements. All these items are brought from areas outside the city, may be from far or near. Creating avenue for production of food and other materials in and around the cities will certainly minimize the pressure on land available outside the city areas. The urban sustainability is at threat due to environmental pollution, rising population and intensification of non-green activities. Many cities have natural resources such as water bodies, inherent vegetation, open space, etc.; which can be appropriately utilized for productive purpose. Promotion of urban agriculture in the form of growing crops, planting trees rearing animals and encouraging landscape garden will have long term impact on urban ecosystem. This can prevent environmental degradation, ensure supply of fresh food and improvement in urban life.

Introduction Beetroot (Beta vulgaris L.) is a very popular herbaceous biennial root vegetable mainly grown for its edible roots and leaves, it is commonly known as Chukander in Hindi, but also has different local names depending on the area, for instance, it is called Bita gacha in Bengali, Bita in Marathi, Beet in Punjab, Salada in Gujarati, Dumpamokka in Telugu, and Bit in Malayalam etc (Kumar, 2015). It belongs to the family Chenopodiaceae (now Amaranthaceae). The chromosome number of beetroot is 2n = 18. It is used as a cooked vegetable, salad, and for pickling and canning. Origin and distribution The origin of beetroot (Beta vulgaris) can be traced back to the Mediterranean region and the Middle East.

Even while the world is ageing, it is not prepared for it. There are 962 million people over 60 in the world as of 2017 with 310.0 million of them living in wealthy countries and 652.2 million in developing ones, according to data from the UN's Department of Economic and Social Affairs (DESA-UN 2017). According to projections, there would be 2.1 billion seniors worldwide by the year 2050 (rich countries: 421.4 million, developing countries: 1670.5 million). By 2030, 80% of the old people in the globe will live in developing countries (DESA-UN, 2015). Elderly individuals in rural developing countries confront challenges such as the lack of pension coverage, work difficulty and high medical costs. Their poor diets and deteriorating poverty raise their risk of chronic illnesses like diabetes, heart disease and cancer (Marshall et al., 2001). 

Introduction

In shrimp farming practice, the production cost of shrimps mainly depends on the feed cost and its associated water quality management issues. Hence, the success of shrimp aquaculture is wholly depends on the feed input cost and this feed cost involved can be reduced to a greater extent by enhancing the organic productivity of the ponds, particularly by enhancing the plankton productivity, which include, the assemblages of phytoplankton and zooplankton.

This chapter begins with an introductory overview, providing a basic understanding of correlation and its types. It guides readers through in-depth analysis using R, demonstrating how to apply these concepts practically.

Correlation

Correlation analysis is a statistical method used to evaluate the strength and direction of the relationship between two variables. This analysis is vital in identifying and understanding how variables are interconnected within a dataset, providing insights into their mutual influences.

Key aspects of correlation include

• Range of the correlation coefficientThe value of the correlation coefficient (“r”) falls within the range of −1 to +1.

• Independence from origin and scaleThe correlation coefficient (“r”) remains consistent regardless of any changes in the origin or scale of the variables.

• Unit independenceThe correlation coefficient is independent of the units of measurement

of the variables.

• Relationship with independenceWhile uncorrelated variables are generally independent, the reverse is not necessarily true; independent variables will always be uncorrelated.

Introduction

A teacher uses different aids in addition to lectures for effective teaching. Similarly, a trainer uses different training methods to make learning effective. In Agricultural Extension the extension worker as a teacher has to design and use appropriate teaching methods depending upon the group to make the teaching effective. According to Leagans (1961) “extension teaching methods are the basic and proven devices used to create situations in which communication can take place between the instructor and the learner.” Extension methods are powerful tools for extension workers to effectively communicate certain messages. Some studies suggest that the adoption of innovations by the farmers requires different teaching methods at different stages of learning. These methods are required for imparting new knowledge and skills to the farmers to adopt new practices for their increased production and income. The choice of extension teaching methods depends on the target audience, location, and availability of time for teaching.

Classification of extension Teaching Methods

Extension teaching methods are classified according to use, form, and function as shown in Table 4.1.

Classification According to Use

The extension methods could be individual or interpersonal, group contact, or mass contact as shown in Figure 4.1.

Individual contact methods: Individual methods provide face- to- face contact with individuals. Those techniques are very effective in teaching new technologies and creating goodwill among farmers and extension people. When few people are to be contacted and they are at a close distance, the individual methods are effective. The extension worker contacts directly to an individual and gets his feedback through different means like personal visits, telephones, SMS, etc. The individual contact method is useful for rapport building and easy to obtain feedback. But the method is time- consuming and quite expensive.

Q10 value: The number of times a reaction rate change with a 10oC change in temperature is called Q10 value. If reaction rate doubles with 10oC change in temperature, Q10 = 2. It is also called temperature quotient.

Q-enzyme: It is a branching enzyme responsible for formation of 1-6 bonds in amylopectin.

QHV process: It stands for Quality Has Value Process.

QO2 : It is a unit for measurement of respiration. Or It is the oxygen uptake in microlitres per milligram on dry weight per hour.

Quailing: In this practice the oranges are kept in the baskets in which they are harvested to allow the fruit to loose little moisture. It is done for a couple of hours before transport to packhouse. This practice would allow the fruit to lose a little moisture which is called quailing. This operation is done for oranges to prevent Oleocellosis.

Qualitative measurement: It is a subjective / objective measurement of the quality of the product for presence of certain compound. It gives the idea of the presence or absence of the particular compound. It deals with the nature of the substance and not its amount or quantity.

1.0 Introduction

Kiwi or kiwifruit (Actinidia deliciosa) belongs to the Actinidiaceae family that is a fruiting vine originated from Yangtze Valley of China. Kiwifruit was named because it resembles a flightless bird, kiwi which is New Zealand’s national symbol. It is also referred as “New Zealand’s horticultural wonder”. In china kiwi was named as Yang Tao and also as “China’s miracle fruit”. Over the past century, kiwis have also acquired a variety of strange names, including “melonette”, “wood berry”, “strange fruit”, “monkey peach, “macaque pear”, “mihoutau”, “Chinese gooseberry” (Tyagi et al., 2015) “vine pear”, “sun peach” and the particularly enticing moniker “hairy bush fruit” (Hugh Cambbell and Julia Haggerty., 2008). Kiwifruit is a nutrient dense fruit which is exceptionally known for its flavour and vitamin C content (Guroo et al., 2017). Digestive potential, antioxidant property, healthy metabolism, immune function and protection from coronary artery disease are the therapeutic benefits of kiwi (Feruguson., 2003; Boeing et al., 2012; Singeltary., 2012). It reduces the risk against cancer (Puri and Manjula., 2018), arteriosclerosis, cardiovascular diseases and irritable bowel syndrome (Chang et al., 2012) as it is a rich source of ascorbic acid and polyphenols. Due to palatability, aromatic compounds present in kiwifruit attract many consumers. Unique flavour and aroma is increased due to the presence of aldehyde E-2-hexenal, methyl benzoate, ethyl butanoate and esters. China tops in kiwifruit production followed by Italy. Two biggest exporters of Kiwi in world are Italy and New Zealand (Testolin & Ferguson, 2009). Kiwifruit has excellent pharmacological profile and it helps in development of nutritional supplements for welfare of mankind. Farmers can earn high return per unit area as it bears heavily every year and has no crop failure. Thus, kiwifruit has bright prospects in our country.

Plant hormone ethylene is involved in a number of physiological activities within the plant system, ranging from seed germination to fruit development. Ethylene acts as a key player in accelerating fruit ripening by regulating the activities of different enzymes, and is responsible for shortening the shelf life and associated post-harvest losses during the storage of fruit crops. However, all fruit crops have different ethylene production capacities and vary in their response to ethylene. Hence, effective management of post-harvest ethylene is imperative for addressing the global challenge of reducing fruit losses after harvesting. In recent periods, numerous technologies and compounds have been developed for the suppression of ethylene and for enhancing in-situ oxidation of ethylene or inhibiting its production at a receptor level. Among these emerging techniques, the use of sachets, fumigating agents, catalysis and composite films embedded with nanoparticles has been found to be trending, but the use of some of compounds has been limited due to health risks or consumer unacceptance. However, most of these technologies are very costly and are not affordable for marginal farmers and developing nations. In order to address these issues, long term breeding approaches for shelf-life improvement, targeting the tfs, ERFs have been involved. This manuscript fills the knowledge gap by encompassing all the recent progress made in enhancing the shelf life of fruits by managing ethylene during storage.
