This document provides an introduction to horticulture. It defines horticulture as the cultivation, processing, and marketing of fruits, vegetables, nuts, and ornamental plants. The four main divisions of horticulture are pomology (fruit culture), olericulture (vegetable culture), floriculture (ornamental horticulture), and landscape architecture. Horticulture is an important industry that provides food, employment opportunities, income, and ornamental plants. It also supports industries like fertilizers, chemicals, machinery, and transportation.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
3. 1. Introduction
• Horticulture is the art and science of cultivating,
processing and marketing fruits, vegetables, nuts, and
ornamental plants.
• In popular parlance, it is simply "garden cultivation"
(L.hortus = garden; cultura = cultivation).
• Unlike agronomic and forest products, which are
generally utilized in the non-living state (e.g., as grains,
fibre, timber, etc.), horticultural produces are largely
used afresh.
• The returns from investment per unit area are generally
higher for horticultural plants than for agricultural and
forest plants.
4. • Nowadays, many colleges and universities have
educational programmes in horticulture.
• Such institutions not only provide training but also
conduct research works in various fields of this
discipline.
• Horticulturists gather informations from other
branches of Botany to raise elite cultivars and to evolve
best cultural practices for their successful production.
• Modern horticulture is a big business.
• It provides employment for skilled people and supports
a number of industries, such as fertilizers, chemicals,
machineries and implements.
• Also, it beautifies the environment and arouses our
aesthetic imaginations.
• Presently, many people, who do not care to grow food
crops, often enjoy growing flowers outdoors and
indoors for aesthetic purposes.
5. Divisions of horticulture
• Horticulture has four major divisions namely
• pomology (fruit culture),
• olericulture (vegetable culture),
• floriculture (ornamental horticulture) and
• landscape architecture.
7. • This is the branch of horticulture that deals with the
production, harvesting, processing, preserving and
marketing of fruits and nuts.
• The farm land, where only fruit trees are grown, is
called an orchard.
• Growing fruits is a long-term operation.
• Fruit trees take long time to come into bearing.
• They also require more growing space than what is
required by vegetables Pomologically important
fruits are of different types.
• Some of them are succulent and juicy (mango, pine
apple, grape, etc.), whereas the others are dry
(cashew, pista, walnut, etc.).
9. • This is the branch of horticulture which deals with
the production of vegetables Some vegetables are
grown for their fruits (e.g., tomato, brinjal), some
others for leaves (e.g.. spinach, amaranth), still
others for tubers (e.g., carrot, beetroot), and yet
others for pods (e.g., peas, beans).
• Unlike fruit plants, vegetables are generally short-
duration plants and so they have to be cultivated
every growing season.
• Vegetables must be harvested and used afresh.
• Vegetable production is one of the most popular
hortiultural activities of common man.
11. • This is the cultivation and use of ornamental plants.
So, it is generally called ornamental horticulture.
• Ornamentals may be cultivated in open spaces or in
indoors.
• They can be grown, arranged, and displayed in
different ways for decorative purposes.
13. • Landscaping is the use of ornamental plants, together with other
elements, to beautify a given area.
• The professionals who design such places are called landscape-
architects.
• Landscaping is an integral part of the construction of houses,
commercial complexes and other public places.
• Playgrounds and parks are examples of public place, where
ornamental plants are grown to beautify the environment.
• An important aspect of landscaping is ground carpeting, usually
with grass.
• A lawn is the basic landscape element in most cases.
• Other plants are then added to this ground cover.
• The branch of horticulture, concerned with the planting of trees, is
called arboriculture.
• Trees are perennial elements in a landscape design. They are large
in size and hence require more space than annual plants.
• The use of plants in beautifying indoors is called interioscaping.
14. Scope of horticulture
• Horticulture is important to society in a variety of ways.
• It acts as sources of food, employment, income and ornamentals.
1. Horticulture as a source of food
• Mankind makes use of horticulture as a source food materials,
such as vegetables, fruits, nuts and berries.
• These food items are rich in carbohydrates, proteins vitamins and
minerals.
• For example, legumes are rich in carbohydrate eins.
• Horticultural products provide balanced diet for human beings.
• Commercial horticulture accounts for most of the horticultural
produces in our county.
• Neumerous house owners are engaged in gardening for fresh fruits
and vegetables .
• It is a hobby and a recreation for many others.
15. 2. Horticulture as a source of ornamentals
• Ornamental plants are cultivated and maintained both as indoors
and outdoors.
• Plants used in landscaping include trees, shrubs, bedding plants
and grasses.
• Ornamentals are formally displayed in arboreta, parks, botanical
gardens, etc. for the amusement of the public.
• Botanical gardens are designed to exhibit a large variety of plant
types for cultural and educational purposes.
• Flowers feature very prominently on several occasions, such as
receptions, funerals and weddings.
• The golf course industry is a major horticultural enterprise that
involves not only turf grasses but also a wide variety of trees,
shrubs, bedding plants and other ornamentals.
• Nowadays, landscaping has become an integral part of home
designs.
16. 3. Horticulture as a source of income
and employment
• Horticulture fetches substantial income by way of selling fruits, vegetables,
flowers, seeds, seedlings, etc.
• Also, it offers plenty of job opportunities, directly or indirectly.
• Many of such jobs require knowledge and training in horticulture.
• The training should be at vocational level or at college level.
• The work may be in indoors or outdoors.
• Collegiate education gives a sound knowledge of the field, offers job
opportunities at supervisory or managerial levels, and provides
opportunities for undertaking investigatory projects or research
programmes.
• The selected categories of jobs that require varying degrees of familiarity
with horticulture include flower grower, extension officer, farm manager,
sales or marketing officer, teacher and researcher.
• These jobs can be obtained by persons trained in other fields also, such as
basic science, engineering, economics, marketing, agribusiness, genetics,
and post-harvest physiology.
17. Horticulture industry
• Horticulture is, in fact, an industry which depends largely on a
variety of chemicals, including fertilizers, pesticides, and
growth hormones.
• Many companies are involved in the manufacture of
chemicals that are used to enhance the growth and field of
plants and to improve the quality of the produces.
• Chemicals (called agro chemicals) constitute an integral part
of modern high-input production practices
• However, crop production using little or no synthetic
chemicals, called organic farming, is steadily gaining
popularity nowadays.
18. • Horticulture industry needs the service of
engineers to design and produce tools and
machineries.
• Machineries and implements are essential for
land preparation, planting, weeding, spraying,
harvesting, storing, and packaging.
• These aids enable the growers to undertake
large-scale production of horticultural plants.
• Home garden versions of some of these
machineries and equipment are also available.
19.
20. • Horticultural produces and products are to be transported
from the areas of production to marketing outlets.
• Due to their quick perishable nature, horticultural produces
and products require special handling in transportation to
retain their quality for a long time.
• Hence, the industry needs effective transportation facility.
• Certain items require refrigeration during transportation and
storage.
• As most horticultural produces are harvested and used afresh,
the ability to preserve their quality in transit is critical to the
industry.
• In certain cases, the produces are harvested before they ripen
in order to increase their shelf life.
• Home gardeners have the advantage of ready access to vine-
ripened and fresh produces.
