  • Lecture 30 Origins of Horticultural Science
    Lecture 30 1 Lecture 30 Origins of Horticultural Science The origin of horticultural science derives from a confl uence of 3 events: the formation of scientifi c societies in the 17th century, the creation of agricultural and horticultural societies in the 18th century, and the establishment of state-supported agricultural research in the 19th century. Two seminal horticultural societies were involved: The Horticultural Society of London (later the Royal Horticulture Society) founded in 1804 and the Society for Horticultural Science (later the American Society for Horticultural Science) founded in 1903. Three horticulturists can be considered as the Fathers of Horticultural Science: Thomas Andrew Knight, John Lindley, and Liberty Hyde Bailey. Philip Miller (1691–1771) Miller was Gardener to the Worshipful Company of Apothecaries at their Botanic Garden in Chelsea and is known as the most important garden writer of the 18th century. The Gardener’s and Florist’s Diction- ary or a Complete System of Horticulture (1724) was followed by a greatly improved edition entitled, The Gardener’s Dictionary containing the Methods of Cultivating and Improving the Kitchen, Fruit and Flower Garden (1731). This book was translated into Dutch, French, German and became a standard reference for a century in both England and America. In the 7th edition (1759), he adopted the Linnaean system of classifi cation. The edition enlarged by Thomas Martyn (1735–1825), Professor of Botany at Cambridge University, has been considered the largest gardening manual to have ever existed. Miller is credited with introducing about 200 American plants. The 16th edition of one of his books, The Gardeners Kalendar (1775)—reprinted in facsimile edition in 1971 by the National Council of State Garden Clubs—gives direc- tions for gardeners month by month and contains an introduction to the science of botany.

  • Introduction to Horticulture 3
    1 Introduction to Horticu ltu re INTRODUCTION Horticulture is a science, as well as, an art of production, utilisation and improvement of horticultural crops, such as fruits and vegetables, spices and condiments, ornamental, plantation, medicinal and aromatic plants. Horticultural crops require intense care in planting, carrying out intercultural operations, manipulation of growth, harvesting, packaging, marketing, storage and processing. India is the second largest producer of fruits and vegetables in the world after China. In India, about 55–60 per cent of the total population depends on agriculture and allied activities. Horticultural crops constitute a significant portion of the total agricultural produce in India. They cover a wide cultivation area and contribute about 28 per cent of the Gross Domestic Product (GDP). These crops account for 37 per cent of the total exports of agricultural commodities from India. SESSION 1: HORTICULTURE AND ITS IMPORTANCE The term horticulture is derived from two Latin words hortus, meaning ‘garden’, and cultura meaning ‘cultivation’. It refers to crops cultivated in an enclosure, i.e., garden cultivation. Chapter -1.indd 1 11-07-2018 11:33:32 NOTES Features and importance Horticulture crops perform a vital role in the Indian economy by generating employment, providing raw material to various food processing industries, and higher farm profitability due to higher production and export earnings from foreign exchange. (a) Horticulture crops are a source of variability in farm produce and diets. (b) They are a source of nutrients, vitamins, minerals, flavour, aroma, dietary fibres, etc. (c) They contain health benefiting compounds and medicines. (d) These crops have aesthetic value and protect the environment.

  • Botany and Horticulture
    Voices from the Past Botany and Horticulture By Kim Black Tape #42 Oral interview conducted by Harold Forbush Transcribed by Theophilus E. Tandoh October 2004 Brigham Young University-Idaho 2 HF: Coming to his office here in the plant science building, for the purpose of making this early morning interview. It is about 7:00 am and Bishop Black with all of his other duties has agreed to share enough so with the interviewer Harold Forbush here on Ricks College campus. Dr. Black would you be so kind as to give me the place of the birth year, your background before you came to Ricks college. KB: I was born June 10th 1937 in Ricks Field, Utah in Southeastern Utah, grew up on a cattle range in Wayne County in Tory. Father has been a Range all his life and I am the youngest of six children. Graduated from Wayne High School, attended Dixie College in St. George for 2 years went on a mission for the Mormon Church to the Gulf State. Returned and went to Utah State where I got my bachelors degree in Agricultural Education. The conclusion of my Bachelors Degree, I was awarded a scholarship to go on to graduate work but I’d like to take a job in the Jordan School District teaching Vocational Agriculture and Botany. While there I continued my education got a Masters Degree at the University of South Dakota during the summers and 1967 came to Ricks College after being here three years took a leave of absence and went back for my doctorates at Oregon State University in Horticulture with emphasis on Physiology.

  • Wood Ash in the Garden Page 1 of 2
    Wood Ash in the Garden Page 1 of 2 Purdue University Consumer Horticulture Department of Horticulture and Landscape Architecture Home / About / New / Wood Ash in the Garden Released 16 November 2000 by B. Rosie Lerner, Extension Consumer Horticulture Specialist Wood stoves and fireplaces are great for warming gardeners' chilly hands and feet, but what are we to do with the resulting ashes? Many gardening books advise throwing these ashes in the garden. Wood ash does have fertilizer value, the amount varying somewhat with the species of wood being used. Generally, wood ash contains less than 10 percent potash, 1 percent phosphate and trace amounts of micro-nutrients such as iron, manganese, boron, copper and zinc. Trace amounts of heavy metals such as lead, cadmium, nickel and chromium also may be present. Wood ash does not contain nitrogen. The largest component of wood ash (about 25 percent) is calcium carbonate, a common liming material that increases soil alkalinity. Wood ash has a very fine particle size, so it reacts rapidly and completely in the soil. Although small amounts of nutrients are applied with wood ash, the main effect is that of a liming agent. Increasing the alkalinity of the soil does affect plant nutrition. Nutrients are most readily available to plants when the soil is slightly acidic. As soil alkalinity increases and the pH rises above 7.0, nutrients such as phosphorus, iron, boron, manganese, copper, zinc and potassium become chemically tied to the soil and less available for plant use. Applying small amounts of wood ash to most soils will not adversely affect your garden crops, and the ash does help replenish some nutrients.

A forest garden tour with Robert Hart was like a tour of Willy Wonka’s chocolate factory with Mr Wonka himself. “Look at this!”, “Try one of these!”. There was something extraordinary about this garden. As you walked around it, an awareness dawned that what surrounded you was more than just a garden – it was like the garden that Alice in Alice in Wonderland can only see through the door she is too small to get through: a tangible taste of something altogether new and wonderful yet also instinctively familiar.

  • Major Diseases of Horticultural Crops and Their Management
    Major Diseases of Horticultural Crops and this Management Dr.G. Thiribhuvanamala, Dr.S.Nakkeeran and Dr. K.Eraivan Arutkani Aiyanathan Department of Plant Pathology Centre for Plant Protection Studies Tamil Nadu Agricultural University Coimbatore – 641 003 Introduction: The Horticulture (fruits including nuts, vegetables including potato, tuber crops, mushroom, ornamental plants including cut flowers, spices, plantation crops and medicinal and aromatic plants) has become a key drivers for economic development in many of the states in the country and it contributes 30.4 per cent to GDP of agriculture, which calls for knowledge and technical backstopping. Intensive cultivation of the high valued horticultural crops, resulted in the outbreak of several diseases of National importance. In recent days, stakeholders import planting materials from North American Countries. Introduction of planting materials also impose threat in the introduction of new diseases not known to be present earlier. However, the diseases, if not managed on a war foot, it will result in drrastic yield reduction and quality of the produces. Hence adoption of suitable management measures with low residue levels in the final produces becomes as a need of the hour. In this regard, this paper gives emphasis on the diagnosis of plant diseases and their management. 293 Diseases of Mango and their management 1. Anthracnose :Colletotrichum gloeosporioides Anthracnose symptoms occur on leaves, twigs, petioles, flower clusters (panicles), and fruits. The incidence of this disease can reach almost 100% in fruit produced under wet or very humid conditions. On leaves, lesions start as small, angular, brown to black spots and later enlarge to form extensive dead areas.

  • Potential Replacement for Peat in Horticulture
    Potential replacement for peat in horticulture. Paul Alexander Royal Horticultural Society The ultimate goal of peat replacement is to use sustainable components, preferably sourced close to market, and to actually add value to the resultant compost mix. The assumption that peat can be replaced with one material is misinformed. It is commonly considered that new potting compost mixes will be a blend of a variety of raw materials that balance the physical and chemical properties of the individual raw materials as well as interacting with any added nutrition and managing the provision of water (for the plant) in a predictable fashion. An understanding of the interaction with pesticides and herbicides is important, as is the ability of plants to withstand being transplanted from soil-less potting composts into soil. Numerous materials have been researched as potential alternatives to peat but the most commonly utilised materials are, coir, green compost, composted bark (pine and spruce/larch mixes) and wood fibres. These meet customer perception that a compost additive should be brown and freely flowing with consistent high quality, supply and cost. These materials also have some beneficial properties but none of them individually either directly replace peat or satisfy all the needs of growers. It is worth considering that by selecting organic materials from specific waste streams or as by-products from other processes horticulture may also have to compete with energy production for raw materials. Coir Coir compost originates from collecting the dust created by rope or matting production that uses the fibres from the outer shell of coconuts (the mesocarp).
