Abstract

The milk from non-bovine species is gaining considerable attention mainly due to the fact that it is consumed by sensitive consumers (infants and elderly). Donkey milk possesses various health benefits, namely, anti-microbial activity, immunomodulation, hypoallergenicity, prevention of cardiovascular diseases which are elaborated in details here. Similarity in nutrition profile among donkey and human milk is discussed in detail. The donkey milk’s yield, its milking technique, effect of lactation on chemical composition and the microbial aspect is also described. As, availability of donkey milk is limited, therefore its processing becomes essential for its usage over a long period of time. Preparation of various donkey milk products like yoghurt, ice cream and cheese are also described here.

3.1. Soil colloids

Clay fraction of the soil contains particles less than 0.002 mm in size.

Particles less than 0.001 mm size possess colloidal properties and are known as soil colloids.

Arecanut (Areca catechu L.) or Betel nut is an extensively cultivated tropical palm, belongs to family Arecaceae, fruit (nut) or dry kernel of this tree is popularly known as the betel nut or supari is used for masticatory or Chewing purpose in India and all over world especially in West and South Asia. The major areca nut growing countries are: India, Sri Lanka, Bangladesh, Nepal, China, Myanmar, Bhutan, Thailand, Malaysia, Indonesia and Vietnam. In India, it is an important commercial crop and also forms part of ritual offerings in Hindu religion. India is the largest producer and largest consumer of Arecanut in the world. The present production of arecanut in India is cultivated in about 4.97 lakh ha with a production of 8.33 lakh tonnes of nuts with the productivity of 1.7MT/ha (Source: Department of Agriculture, Govt. of India, 2018). Arecanut is predominantly cultivated in traditional states like Karnataka, Assam, Kerala, Maharashtra, West Bengal and Andaman and Nicobar group of Islands and it’s cultivation is spread to non-traditional areas in Kamataka and Tamil Nadu. Areca nut is providing livelihood security for millions of people in rural and urban areas.

The seed contains alkaloids such as arecaidine and arecoline, which, when chewed, are intoxicating and slightly addictive. The seed also contains condensed tannins (procyanidins) called arecatannins. Chewing the mixture of arecanut and betel leaf is a tradition, custom or ritual which dates back thousands of years in much of the geographical areas from South Asia eastward to the Pacific.

Manures are the plant and animal wastes that are used as source of plant nutrients. They release nutrients upon their decomposition.

Bulky organic manures contain small percentage of nutrients and they are applied in large quantities. e.g,. farmyard manure, compost, green manures.

P680: Reaction center chlorophyll in Photosystem II (PSII) which absorbs maximum light of 680 nm in its neutral state.

P700: Reaction center chlorophyll in Photosystem I (PSI) which absorbs maximum light of 700 nm in its neutral state.

P870: Form of bacteriochlorophyll in reaction center of pigment system in photosynthetic purple bacteria that absorbs light maximally at 870 nm in its neutral state.

Paclobutrazol: It is a chemical compound which inhibits Gibberellin biosynthesis. It is also a growth retardant commercially used in overcoming alternate bearing of mango.

Palindrome: Inverted repeats of DNA such that the sequence is the same when read forward or backward; e.g., CAGTTGAC, or in the English language, “Madam, I’m Adam.”

Palisade Parenchyma : Palisade parenchyma cells are seen beneath the upper epidermis. It consists of vertically elongated cylindrical cells in one or more layers. These cells are compactly arranged without intercellular spaces. Palisade parenchyma cells contain more chloroplasts than the spongy parenchyma cells. The function of palisade parenchyma is photosynthesis.

Pantothenic acid (Vitamin B₅): An important constituent of coenzyme A which is involved in transacylation reactions.

Lignieres and Spitz first isolated Actinobacillus from the cattle with actinomycosis like condition in Argentina in 1902. The findings were also confirmed by Nocard in 1902. Later the isolated bacterium from the cattle was named as Actinobacillus lignieresii in memory of Lignieres.

Pfeiffer (1892) first isolated Haemophilus influenzae as a cause of human influenza and it is also known as ‘Pfeiffer’s bacillus’. Other workers isolated and described different species of the genus Haemophilus from animals and birds. In 1903, Friedberger, a research assistant of Pfeiffer, isolated similar kind of bacteria from prepuce of dogs which was described later as Haemophilus canis. In 1925, Mitchell isolated Haemophilus ovis from the respiratory tract of sheep. Lewis and Shope (1931) isolated and illustrated Haemophilus suis from the infected pigs. Glasser found the association between fibrinous serositis, polyarthritis in pigs (Glasser’s disease) and a small gram-negative rod as early as 1910, later became known as Haemophilus parasuis. The bacteria was first isolated by Hjarre and Wramby in 1943. De Blieck (1931) isolated a hemophilic bacterium from the birds suffering with ‘infectious coryza’ and named the bacteria as Bacillus haemoglobinophilus coryzae gallinarum. Later it became known as Haemophilus paragallinarum (Avibacterium paragallinarum).

The method to preserve foods in sealed glass bottles by heat in boiling water was developed by one among the following scientist?

a) Edward Jenner (1798) b) Francois Nicolas Appert (1804)

c) Lazzaro spallanzani (1765) d) None of the above

Objectives

1. To know about the seed treatment of spices and condiments.
2. To know the sowing method and time of spices and condiments.

Seed treatments or seed dressing: Seed treatment refers to the application of fungicide, insecticide, or a combination of both, to seeds so as to disinfect and disinfect them from seed-borne or soil-borne pathogenic organisms and storage insects. It also refers to the subjecting of seeds to solar energy exposure, immersion in conditioned water, etc. The seed treatment is done to achieve the following benefits.

Advantages of seed treatment

1. Protects germinating seeds and seedlings against soil and seed borne pathogens/insects.
2. Seed germination enhancement.
3. Early and uniform establishment and growth
4. Enhances nodulation in legume crop.
5. Better than soil and foliar application.
6. Uniform crop stand, even in adverse conditions (less/high moisture)

Liver is the largest exocrine gland located in right side of the abdominal cavity
obliquely from lumbocostal angle downward and forward to intercostal space,
about 3-4” (10 cm) above the abdominal floor.

In several cucurbits as well as other crops, BER is a physiological condition found (for example, tomato, brinjal and pepper). It typically occurs as a general rot at the flowering end of rising fruit. Usually, the blossom end rot is the result of inadequate or uneven irrigation, high humidity, or other variables that slow the flow of water through the plant. Slow water movement may also result in temporary calcium deficiencies leading to blossom end rot as calcium is added into the plant with the transpiration stream.

The common pear (Pyrus communis) is known as French Pear, Asian pear also called Chinese pears, Japanese pears, Oriental pears, sand pear, salad pears and apple and pear are group of pome fruits derived from Pyrus ussuriensis and Pyrus serotina. Pyrus communis is susceptible to fireblight disease, however, Pyrus pyrifolia is resistant to this disease. Pear is only temperate fruit grown on the hills to southern parts of India. Jammu and Kashmir is leading in quality pear production.

Important Points to Remember

ROSE

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.

Endowed with varied agro-climatic situations, topography and soil type, India has been a leading vegetable producing country in the world occupying the second
position in vegetable production after China with an annual production of 87.53 million tonnes from 5.86 million hectares having a share of 14.4 per cent to the world production. With commercial cultivation of as many as 61 annual and 4 perennial vegetables, India is the most diverse vegetable growing country in the world (Prakash et al., 2006).

Abstract

Biological databases that are composed of a large collection of digital nucleic acid sequences, protein sequences, or other polymer sequences stored on a computer, which is made available to the research community worldwide using web servers. The vast amount of information generated in molecular biology is analyzed, curated, tabulated, and arranged in databases. There are different types of biological databases, based on their contents. Besides, the database management system, a program to manage the databases, can be of two types: distributed DBMS and relational DBMS. This chapter briefly narrates the importance and purpose of biological databases.

With Judicious Use of Herbicides

Herbicides are the chemicals used for killing or suppressing the growth of weed plants from field / horticulture / plantation crops as well as non-cropped areas/ water bodies etc. The herbicide is said to be an ideal herbicide when it is very safe to the crop on which it is applied and on the other hand, it must control all associated weeds effectively. Also, ideal herbicides should leave no residual effects on the succeeding crop(s). Herbicides are of two types i.e.

1. Selective herbicides and
2. Non-selective herbicides.

A selective herbicide is that which is very safe to crop plants but unsafe to weed plants e.g. atrazine in maize, clodinafop in wheat etc. On the other hand, non-selective herbicides are those which kill all green plants including crop and weed plants which come in their contact e.g. paraquat and glufosinate ammonium.

Introduction The botanical name of carrot is Raphanus sativus which belongs to the family Brassicaceae having haploid chromosome number of x = 9 and is believed to be originated from Europe and Asia. Radish is one of the most ancient and popular leaf cum root vegetables in both tropical and temperate regions. Radish probably originated in Europe and Asia. Radishes were extensively cultivated in Egypt and ancient records show that radishes were eaten before the pyramids were built. It had spread to China during 500 BC and to Japan during AD 700. The recent study has indicated that east of Mediterranean region, most probably China is the centre of origin of radish. Wild state of radish is not known. Previously it was believed to haveevolved from a common weed Raphanus raphanistrum Linn in Europe but now it is believed to have been evolved from more a variety of sources. As it is a short duration annual or biennial crop, it can be widely used in sequence cropping, companion cropping and intercropping in widely spaced crops. Roots are pink in colour due to presence of anthocyanin pigment.

It is commonly spread by coitus and also by licking and rubbing of the affected area. It is more common in active breeding dogs.

Introduction

Technical innovation is a process by which new or improved technologies are developed and brought to widespread use (Ambuj Sagar, 2013). Technical innovations are interlinked by research, development, demonstration and deployment which involves a range of organizations and personals with institutional arrangements underpinning the growth and advancement of different kinds of technologies. In the area of water productivity, technical innovations has helped expand water supplies through improved exploration and recovery techniques, increased water use efficiency, improved water availability and reduced environmental impact of water and its usage.

The main micro and macro nutrients associated with microgreens are Fe, Zn, K, Ca, N, P, S, Mn, Se and others. Microgreens are a fantastic source of biological phytochemicals, which can significantly improve both human health and disease. In addition to these mineral components, the key bioactive compounds including ascorbic acid, phylloquinone, tocopherol, beta-carotene, phenolic antioxidants, carotenoids, anthocyanins, glucosinolates and sugar content are said to be present in higher concentrations in microgreens. The numerous bioactive phytochemicals (Table 2) that are present in the various types of microgreens are covered in more detail in the ensuing subsections:
