Study Notes

Fundamentals of Horticulture

This book is about the fundamentals of horticulture, authored by Dr. G.S.K. Swamy and Dr. J. Auxcilia.
The book covers various aspects of horticulture, including lectures on topics like Introduction, Horticultural Crops and Human Nutrition, Climatic Requirements, Horticultural Zones of India, Soil Requirements, Nursery Management, Planning of Orchards, Orchard Management, Water Management, Manures and Manuring, Weed Management in Orchards, Training and Pruning, Top Working, Problem of Unfruitfulness, Organic Farming, Maturity Indices for Fruits, Marketing of Fruits, and more.
The authors provide an index of each lecture and the corresponding page numbers.
The book is intended to be a comprehensive study material for students of horticulture.

Topic: Introduction

India is the seventh largest country in the world (328.73 m ha) and has the second-largest population (121 crores in 2011).
India has 144 million hectares of arable land, with 70% under rainfed cultivation.
Horticulture crops account for a significant portion of total agricultural production in the country.
Horticulture is derived from the Latin words "hortus" (meaning garden) and "cultura" (meaning cultivation).

Topic: Horticultural Crops and Human Nutrition

Fruits and vegetables are crucial for a balanced diet, providing essential nutrients and energy.
They are a cost-effective source of nutrients, vitamins, and minerals for human health.
Many Indians are vegetarians; therefore, including horticultural crops in their daily diet is vital.

Topic: Climatic Requirements

Climate is a crucial factor in crop selection for a particular region.
Climate is the totality of the average atmospheric phenomena in a region calculated over thirty years.
The essential elements are light, heat, water, and air.
Climate affects crop choices and plant development.

Topic: Horticultural Zones of India

India is divided into tropical, subtropical, and temperate regions for horticultural purposes.
Specific zones are identified for suitability of various crops based on climate and soil characteristics.
These classifications are used in proper crop selection for different areas of India.

Topic: Soil Requirements

Soil is the top layer of earth supporting plant growth.
It is made up of minerals, clay, organic matter, and water in particular ratios.
Important aspects of soil management in horticultural contexts include slope and erosion hazard, soil depth, drainage, workability, stoniness/rockiness, water holding capacity, permeability, fertility, salinity, alkalinity, and acidity hazards.

Topic: Water Management

Water plays a vital role in plant growth, processes like photosynthesis and respiration, transport of nutrients, maintenance of soil temperature, and soil-microclimate.
Irrigation techniques include flooding, basin systems, furrow systems, ring systems, surface irrigation, overhead irrigation, and drip irrigation.
Factors influencing irrigation decisions include topography, soil characteristics, type of plant, and weather.

Topic: Manures and Manuring

Manures and manuring are essential for crop development.
Inorganic fertilizers (synthetic, high nutrient content) and organic fertilizers (natural, enhance soil health).
Placement and timing of manure application are crucial for crop success and soil health.

Topic: Weed Management in Orchards

Weeds compete with crops for resources like moisture, nutrients, and light.
They reduce crop yields and spread pests and diseases.
Methods for weed control include cultural, biological, chemical, and integrated methods.

Topic: Training and Pruning

Training and pruning are essential to manage the shape, size, and direction of plant growth.
They are techniques for controlling a plant's growth, which are tailored for the specific needs and characteristics of a particular fruit tree and region.
Types of pruning methods include heading back and thinning out.

Topic: Top Working

Top working is a technique for renewing and upgrading plants with different varieties.
It's a method suitable for uplifting seedling plantations, improving orchard productivity, and managing old/poor-quality orchards.

Topic: Problem of Unfruitfulness

Fruit trees may not fruit regularly.
Causes can be genetic (evolutionary tendencies, genetic influences, physiological factors), or environmental (incorrect soil, water, weather, pests, and diseases).
Corrective measures include proper variety selection, management practices, and addressing environmental issues that may lead to unfruitfulness.

Topic: Organic Farming

Organic farming is a sustainable alternative to conventional farming.
It aims to conserve soil and maintain fertility without synthetic pesticides, fertilizers, or other external inputs.
Organic farms promote biodiversity and enhance soil health, leading to higher-quality produce with reduced risk to human health.

Topic: Plant Growth Regulators

Plant growth regulators are chemical substances (other than nutrients) that influence plant growth and development.
They promote, inhibit, or otherwise modify plant physiological processes in controlled amounts.
Common growth regulators include auxins, gibberellins, cytokinins, and ethylene.

Topic: Maturity Indices for Fruits

Maturity indices for fruits are used to determine appropriate time for harvesting, evaluating quality, and assessing post-harvest shelf life.
The indices depend on the fruit type and can involve visual observations, physical testing, and measurements.

Topic: Marketing of Fruits

Marketing is vital for bringing fruits from producers to consumers.
This process involves various activities, including assembling, transporting, handling, distributing, and sales to consumers.
Considerations in marketing include the nature of demand, product quality, transportation, communication, and public policy.
