Agriculture vs Agricultural Science
Agriculture (Latin: "cultivation of the field") involves the cultivation of crops, rearing of livestock, and related industries such as supplying fertilizers, seeds, chemicals, and technology. It also includes marketing and processing.
Agricultural Science is a branch of Biology that includes the study of natural, economic, and social sciences that are used in the practice and understanding of agriculture.
Farming Systems
Conventional Farming System
Modern farming methods designed to produce large quantities of food to be sold for profit. One conventional method is monoculture, where the same type of crop is grown year after year on the same land (e.g., rice cultivation). Monoculture may lead to destruction of natural ecosystems through use of pesticides, inorganic fertilizers, and deforestation.
Traditional Farming System
Involves mixed farming, which is better for the environment. Wastes from animals are used as fertilizers for plants. Farms are not as large as modern monoculture systems.
Non-Conventional Farming Systems
Developed in response to concerns about conventional systems' impact on the environment. More labor-intensive with lower yields but produces better quality food with higher market value.
- Aquaponics: Combination of raising fish in tanks with soilless plant culture (hydroponics)
- Hydroponics: Growing plants without soil using mineral nutrient solutions in water
- Grow box: Partially or completely enclosed system for raising plants indoors
- Trough culture: Growing plants in raised troughs above soilless mixtures
- Peri-Urban farming: Agriculture practices within and around cities
- Organic Farming: Growing crops without synthetic fertilizers and pesticides
Organic Farming Principles
- Maintenance of Ecological Balance and Biodiversity: Reduce negative effects on natural environment, use available lands efficiently to prevent deforestation.
- Integrated Pest and Disease Management: Combination of approaches to control pathogens (biological control, limited chemical use, natural chemicals like neem for parasites, aloe vera in poultry).
- Companion Planting: Using one species' advantages to help another (e.g., garlic repels insects, basil repels mosquitoes).
Weed and Pest Control on Organic Farms
Weed Control: Hand-weeding, hoeing, mulching with composts, plastic films, biological controls (ducks and fish in rice fields to feed on weeds and insects). Herbicides are not encouraged.
Pest Control: Organic pesticides (Bt, Pyrethrum, Rotenone) combined with biological pest control and cultural methods. This is called Integrated Pest Management (IPM).
Importance of Agriculture
1. Foreign Exchange
When agricultural produce is exported to other countries, foreign exchange is earned. Importation of agricultural products results in loss of revenue.
2. Contribution to Gross National Product (GNP)
GNP is a broad measure of a nation's total economic activity. Agriculture significantly contributes to this measure.
3. Food Security
Producing enough food to sustain the country reduces need to import food items from foreign countries.
4. Employment
Agricultural sector provides jobs in farming, agricultural education, marketing, and engineering. Growing more food locally creates more jobs.
5. Trade Liberalization
Removal or reduction of restrictions on free exchange of goods between nations causes greater competition, resulting in countries making greater effort to produce higher quality agricultural products.

- Secondary Production: Processing of raw materials into secondary products (e.g., pineapple juice, sugar from sugarcane)
Goods and Services in Agriculture
Goods:
- Capital goods: Farm tractors, dairy herd - goods that exist on a farm
- Consumable goods: Essential for human nutrition (foodstuffs)
Services:
- Commercial: Provided by agri-supply stores and livestock depots

Test Your Knowledge - Introduction to Agriculture
Question 1: Compare and contrast conventional and non-conventional farming systems.
Conventional farming refers to modern farming methods designed to produce large quantities of food for profit, often using monoculture, pesticides, and inorganic fertilizers. It is high-yielding but can harm the environment.
Non-conventional farming was developed in response to environmental concerns about conventional systems. It is more labor-intensive, produces lower yields but better quality food with higher market value. Examples include aquaponics, hydroponics, and organic farming.
Traditional farming involves mixed farming, uses animal waste as fertilizers, and is better for the environment than conventional systems.
Question 2: Explain THREE principles of organic farming and give an example for each.
- Maintenance of ecological balance and biodiversity: Using available lands efficiently to prevent deforestation and reduce negative environmental effects.
- Integrated pest and disease management: Combining different approaches like biological control (using natural predators), limited chemical use, and naturally occurring chemicals (neem for controlling internal parasites in animals).
- Companion planting: Using one species' advantages to help another (garlic repels many insects, basil repels mosquitoes when planted alongside other crops).
Question 3: Describe THREE major challenges faced by Caribbean farmers and suggest possible solutions.
Challenge 1: Climate and Topography - Caribbean countries have hilly terrain making machine operation difficult, and shallow topsoil prone to erosion.
Solution: Implement terracing on slopes, use contour ploughing, and select crops suitable for hilly terrain.
Challenge 2: Praedial Larceny - Theft of agricultural produce adds to production costs, especially for crops easy to harvest.
Solution: Implement farm security measures, community watch programs, and insurance against theft.
Challenge 3: Access to Finance - High interest rates make it difficult for farmers to access capital.
Solution: Government subsidies, low-interest agricultural loans, and farmer cooperatives for collective financing.
Question 4: What are the FIVE main functions of marketing in agriculture?
- Merchandising: Buying, pricing, and selling of agricultural products
- Handling: Transportation, grading, assembling, and storage of products
- Processing: Manufacturing, packaging, and labeling to add value to products
- Supporting: Financing, risk-bearing (insurance), and market intelligence
- Distribution: Moving products from producers to consumers through various channels
Section B: Crop Production
Plant Anatomy and Physiology
Uses of Plants in Agriculture
- Food: Plants provide food for humans and livestock
- Feed Fibre: Parts not consumed by humans can feed livestock
- Fuel: Corn produces biofuel (ethanol)
- Medicine: Over 50% of prescription medicines are derived from plants
- Ornamentals: Decorative purposes (botanical gardens)
External Structure of Plants
Principal Parts of a Vascular Plant:
- Shoot System: Flower, leaf, bud, stem
- Root System: Primary root, lateral roots, root hairs, root cap
Types of Root Systems:
- Tap Root: Main root with lateral roots at sides
- Fibrous Root: Cluster of roots growing from base of plant (coconut, corn)
- Adventitious Roots: Grow from base of stem cuttings (croton) or leaves (Bryophyllum)
- Aerial Roots: Grow above ground (mangrove)
Internal Structure of Plants
Root Structure (Dicotyledonous Plants):
- Epidermis: Single cell layer with root hairs for absorption
- Cortex: Unspecialized cells transporting water and minerals
- Endodermis: Separates cortex from vascular tissues
- Vascular Tissues: Xylem (transports water/minerals) and Phloem (transports food)
- Pericycle: Produces more vascular tissues
Plant Physiology
Photosynthesis
Process where plants use solar energy to manufacture food (chemical energy).
Two Stages:
- Light Reaction: Occurs in presence of light; light energy splits water into hydrogen and oxygen
- Dark Reaction: Light not needed; hydrogen combines with carbon dioxide to make sugar
Overall Reaction: Carbon Dioxide + Water → Glucose + Oxygen
Rate affected by: Light intensity, temperature, water availability, oxygen and carbon dioxide concentration, leaf anatomy, chlorophyll distribution.
Sugar uses: Respiration (energy release), starch storage, creating proteins and lipids.
Respiration
Oxidation of organic substances (e.g., glucose) in living cells to produce energy.
Overall Reaction: Glucose + Oxygen → Water + Carbon Dioxide + Energy
Chemical Equation: C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + ATP
Rate affected by: Condition of protoplasm, temperature, oxygen concentration, stored food.
Transpiration
Evaporation of water from leaves mainly through stomata. Creates cooling effect and causes transpiration stream (continuous movement of water up xylem).
Importance: Brings dissolved minerals (e.g., magnesium for chlorophyll formation), keeps cells turgid (rigid).
Wilting: When transpiration rate exceeds water absorption. Temporary wilting reversible with water; permanent wilting causes plant death.
Translocation
Movement of organic and inorganic substances within plant. Phloem transports manufactured food; xylem transports water and mineral salts.
Photoperiodism
Response of plants to changes in duration of light and darkness.
- Short-day plants: Flower with long darkness and short light periods (rice, soybean, onion)
- Long-day plants: Flower with long light periods (more than 12 hours) (radish, lettuce)
- Day Neutral plants: Flower regardless of day length (tomatoes, corn, cucumbers)
Phototropism
Growth of plants in response to light stimulus. Shoots grow toward light due to auxin distribution (auxins move away from light, causing slower growth on light-exposed side and faster growth on opposite side).
Plant Reproduction
Sexual Reproduction
Fusion of male and female gametes to form new offspring. Involves two parents contributing gametes.
Parts of a Flower:
| Structure | Function |
|---|---|
| Anther | Produces pollen grains (male gametes) |
| Stigma | Allows pollen to attach |
| Ovary | Matures into fruit |
| Ovule | Egg development occurs; forms seed |
| Style | Supports stigma, assists fertilization |
| Petals | Attract pollinators if colorful |
| Sepals | Protect reproductive structures |
Pollination
Transfer of pollen grains to stigma.
Types:
- Self-pollination: Pollen deposited on stigma of same flower or same plant
- Cross-pollination: Pollen transferred to different flower
Wind vs Insect Pollinated Flowers:
| Wind Pollinated | Insect Pollinated |
|---|---|
| Odourless, no nectar | Sweet scented with nectar |
| Small, light, smooth pollen | Large, sticky pollen |
| Feathery stigma | Smooth, sticky stigma |
| Stigma and anther hang outside | Stigma and anther inside flower |
Fertilization in Flowering Plants
Step-by-step process:
- Pollen grain lands on stigma; pollen tube develops
- Pollen tube grows into style carrying two male nuclei
- Pollen enters ovary via micropyle; nuclei enter
- One male nucleus fuses with female gamete (egg cell) → embryo
- Another male nucleus fuses with central cell → endosperm (food storage)
Asexual Reproduction
New organism produced from single parent without gametes.
Natural Vegetative Propagation: Using perennating organs (store nutrients):
- Rhizomes: Underground stems growing horizontally (ginger, turmeric)
- Tubers: Stem tubers (Irish potato, yam) and root tubers (sweet potato)
- Corms: Underground stem food storage (dasheen)
- Bulbs: Short stem with fleshy leaves (onion, garlic)
- Suckers: Shoots from underground roots/stems (plantain, banana, sugarcane)
- Stolons: Stems growing at soil surface forming adventitious roots (nut grass)
- Runners: Stem portions growing horizontally (strawberry, pumpkin)

Germination
Process where embryo develops into seedling using stored food.
Types:
- Epigeal: Cotyledons rise above ground (kidney bean, tomato, cabbage)
- Hypogeal: Cotyledons remain below ground (coconut, maize, broad bean)
Conditions for Germination:
- Water: Activates enzymes to use stored food
- Oxygen: Needed for respiration and energy production
- Suitable Temperature: Allows enzymes to function properly
Seed Viability: Ability to germinate, expressed as percentage. Affected by storage conditions (cool, sealed containers maintain viability).
Scarification: Weakening or altering hard seed coat to encourage germination.
Environmental Factors Affecting Crop Growth
Aerial Factors
- Rainfall: Provides water for growth; excess causes waterlogging; absence causes wilting.
- Temperature: Controls metabolic rate; moderate temperature best for growth.
- Sunlight: Needed for photosynthesis; plants in dark develop etiolation (long slender stems, unexpanded leaves, lack chlorophyll).
- Wind: Affects transpiration rate; higher wind increases transpiration.
- Humidity: Amount of moisture in atmosphere; high humidity slows transpiration.
Soil Factors
Soil Fertility: Important for plant growth; low fertility causes slow growth and reduced yields.
Soil Science

- Chemical: Breakdown through chemical changes (reaction with water, air, acids)
- Biological: Breakdown by living things (burrowing animals, plant roots)
Parent Material: Determines soil type (shale → clay soil; sandstone → sandy soil).
Soil Profile
Layers (horizons) formed as soils develop over time.
Main Horizons:

Animal Genetics, Breeding and Reproduction
Breeding Systems
| System | Description | Advantages | Disadvantages |
|---|---|---|---|
| Cross-Breeding | Mating animals from two different breeds | Hybrid vigor, improved productivity, disease resistance | May lose pure breed characteristics |
| Upgrading | Crossing native breed with imported breed | Introduces desirable characteristics, improves local breeds | Multiple generations needed |
| In-Breeding | Mating closely related animals | Maintains desirable characteristics, fixes traits | Inbreeding depression (reduced fertility, growth, disease resistance) |
| Back-Crossing | Mating hybrid with one of its parents | Maintains desirable characteristics without new genes | Limited genetic diversity |
Artificial Insemination
Introduction of semen from selected male into female reproductive tract by trained person.
Process:
- Semen collected from male using artificial vagina
- Semen diluted with sugar, salts, glycerol, antibiotics
- Stored in plastic straws frozen in liquid nitrogen (-196°C)
- Thawed before use; inserted into female during heat period
Animals: Cattle, sheep, goats, pigs.
Advantages: Use semen from superior males, disease control, genetic improvement, no need to keep males.
Animal Reproduction
Key Terms:
- Ovulation: Release of egg/oocyte
- Spontaneous Ovulation: Egg released based on cycle
- Induced Ovulation: Ovulation due to external stimulus (mating)
- Fertilization: Fusion of male and female gametes
- Gestation: Period between conception and birth (parturition)
Oestrus Cycle: Begins from one heat period to next; controlled by hormones; heat period is when female sexually receptive.
Signs of Pregnancy: Absence of heat, increased abdomen size, udder/teat development, milk vein development.
Care of Young Animals
Brooding in Poultry:
- Natural Brooding: Hen incubates eggs and cares for chicks
- Artificial Brooding: Day-old chicks housed in specially prepared area with heat, light, proper conditions
- Management: Cleanliness, health protection (vaccination), proper feed and water, temperature control (35°C initially, reducing by 2°C weekly)
Care of Young Rabbits (Kittens): Keep warm, ensure mother feeds them, provide proper nesting material.
Test Your Knowledge - Animal Production
Question 1: Compare and contrast the digestive systems of ruminants and non-ruminants.
| Aspect | Ruminants (Cattle, Sheep, Goats) | Non-Ruminants (Pigs, Poultry) |
|---|---|---|
| Stomach Type | Four-compartment stomach (rumen, reticulum, omasum, abomasum) | Simple stomach (monogastric) |
| Food Processing | Chew cud; regurgitate food for re-chewing | No cud-chewing; food passes through once |
| Cellulose Digestion | Bacteria/protozoa in rumen ferment cellulose | Limited cellulose digestion; different adaptations |
| Examples | Cattle, sheep, goats | Pigs, poultry, rabbits |
| Special Adaptations | Rumen fermentation, cud-chewing | Poultry: crop, gizzard; Rabbits: coprophagy |
Question 2: Explain the importance of Feed Conversion Ratio (FCR) in animal production.
Feed Conversion Ratio (FCR) is a mathematical relationship between the quantity of feed provided and the weight gained by an animal consuming it. It is expressed as a ratio (e.g., 3:1 means 3 kg of feed produces 1 kg of weight gain).
Importance in Animal Production:
- Economic Efficiency: Lower FCR means less feed is needed for each unit of weight gain, reducing production costs.
- Breed Selection: Helps farmers choose breeds with better feed efficiency (lower FCR).
- Management Decisions: Identifies optimal slaughter time when FCR becomes less efficient.
- Resource Optimization: Helps minimize feed wastage and maximize profit.
- Health Monitoring: Increasing FCR may indicate health problems or poor management.
Average FCRs: Cattle 4.5-5.0:1, Pigs 3.5-4.0:1, Goats 4.5-5.0:1, Rabbits 3.0-3.5:1, Chickens 3.0-3.5:1.
Question 3: Describe THREE common poultry diseases and their prevention/control measures.

2. Coccidiosis:
- Causative Agent: Protozoan (coccidia)
- Symptoms: Droopiness, loss of appetite, swollen and bloody cloaca, moderate mortality
- Prevention/Control: Sulfa drugs in drinking water, magnesium sulfate, remove birds from wet litter, proper sanitation
3. Fowl Pox:
- Causative Agent: Virus
- Symptoms: Warts all over body developing into black scabs on wattles and beak
- Prevention/Control: Vaccination, isolate diseased animals, burn or bury carcasses, control mosquitoes (vectors)
Question 4: Compare artificial insemination with natural mating in animal breeding.
| Aspect | Artificial Insemination | Natural Mating |
|---|---|---|
| Process | Semen collected from male and introduced into female reproductive tract by trained person | Male and female animals mate naturally |
| Genetic Improvement | Can use semen from superior males worldwide; rapid genetic improvement | Limited to available males in locality; slower genetic improvement |
| Disease Control | Reduces disease transmission; semen tested for diseases | Higher risk of disease transmission between animals |
| Cost | Higher initial cost for equipment/training; lower long-term cost (no male maintenance) | Lower initial cost; higher long-term cost (maintaining males) |
| Record Keeping | Accurate records of parentage and breeding dates | Less accurate records; may not know exact breeding date |
| Labor/Skill | Requires trained personnel and proper equipment | Requires less skill; animals mate naturally |

Demand, Supply and Pricing
Key Concepts
- Demand: Quantity consumers are willing to buy at certain price
- Supply: Quantity sellers are willing to offer at certain price
- Law of Demand: As price increases, quantity demanded decreases (inverse relationship)
- Law of Supply: As price increases, quantity supplied increases (direct relationship)
- Equilibrium Price: Where demand equals supply
Factors Affecting Demand
- Change in taste and preference
- Change in income
- New products introduced
- Change in prices of other commodities
- Change in taxes and duties
- Change in product advertising
Factors Affecting Supply
- High consumption by producers (less to market)
- Change in cost of production
- Change in production techniques
- Changes in weather
- Taxation
- Changes in future expectations
Law of Diminishing Returns
Definition and Application
As more units of variable input are added to fixed inputs, there comes a point where each additional unit yields progressively smaller increases in output.
Example: Adding fertilizer to crops increases yield up to a point, but beyond that, additional fertilizer produces smaller increases or may decrease yield.
Three Stages:
- Stage 1: Total product increasing rapidly; average product equals marginal product
- Stage 2: Average and marginal product declining; total product still increasing but slower
- Stage 3: Inefficient stage; total and average product decrease; marginal product negative
Cost Concepts
- Fixed Cost (FC): Does not change with production level (land rental, machinery, buildings)
- Variable Cost (VC): Changes with production level (feed, fuel, pesticides)
- Total Cost (TC): FC + VC
- Average Cost (AC): TC / Number of units of output
- Marginal Cost (MC): Increase in TC from producing one more unit

Test Your Knowledge - Business of Farming
Question 1: Explain the four factors of production in agriculture with examples.
1. Land: The physical space and natural resources used for agricultural production.
Examples: Farmland, pasture, forests, water sources.
Characteristics: Limited resource, suitability depends on climate and topography, can be lost to other uses or degraded through over-cultivation.
2. Labour: The human effort involved in farming operations.
Examples: Family labour (unpaid), casual labour (temporary paid workers), seasonal labour (for planting/harvesting), contract labour (for specific tasks).
Characteristics: Limited availability due to migration to urban areas, aging farming population.
3. Capital: The wealth (money, equipment, buildings) used to produce agricultural goods.
Examples: Fixed capital (land, buildings, machinery), working capital (money for day-to-day operations).
Characteristics: Sources include banks, cooperatives, personal savings; often difficult to access due to high interest rates.
4. Management: The organization and coordination of the other factors for efficient production.
Examples: Farmer as manager (small farms), employed farm manager (large farms).
Characteristics: Involves planning, organizing, directing workers, supervising operations for sustained output with high quality.
Question 2: Describe the law of diminishing returns and its importance in farm management.
Law of Diminishing Returns: As more units of a variable input (like fertilizer, labour, or water) are added to fixed inputs (like land), there comes a point where each additional unit of input yields progressively smaller increases in output.
Example in Agriculture: Adding fertilizer to a crop increases yield up to a certain point. The first units of fertilizer produce large yield increases, but additional units produce smaller increases, and beyond the optimal point, may even decrease yield or cause damage.
Three Stages:
- Stage 1: Increasing returns - each additional input unit produces larger output increases
- Stage 2: Diminishing returns - each additional input unit produces smaller output increases
- Stage 3: Negative returns - additional input units actually decrease total output
Importance in Farm Management:
- Optimal Resource Use: Helps farmers determine the most efficient level of input application
- Cost Management: Prevents wasteful spending on inputs beyond the point of diminishing returns
- Profit Maximization: Identifies the point where marginal cost equals marginal revenue for maximum profit
- Sustainable Practices: Prevents over-application of inputs that could harm the environment
- Decision Making: Guides decisions on fertilizer rates, irrigation amounts, labour allocation
Question 3: Compare and contrast complete and partial budgets in farm planning.
| Aspect | Complete Budget | Partial Budget |
|---|---|---|
| Purpose | Comprehensive financial plan for entire farm or major changes | Analysis of specific changes in existing farm plan |
| When Used | New farm, new owner/management, major reorganization, new technologies | Specific changes (replacing one crop with another, hiring vs purchasing equipment) |
| Scope | All farm enterprises and operations | Only affected enterprises or operations |
| Components | Total income, variable expenses, fixed expenses, profit calculation | Additional costs/reduced income vs additional income/reduced costs |
| Complexity | More complex, time-consuming | Simpler, focused analysis |
| Example | Budget for new mixed farm with multiple enterprises | Budget comparing cost of replacing corn with soybeans on 100 acres |
Similarities: Both help in decision-making, both involve financial analysis, both consider costs and returns, both used for planning purposes.
Question 4: Explain THREE benefits of agricultural cooperatives to small farmers.
1. Economic Benefits:
- Bulk Purchasing Power: Cooperatives can buy inputs (seeds, fertilizers, equipment) in bulk at lower prices than individual farmers.
- Better Marketing: Collective selling gives farmers more bargaining power and better prices for their products.
- Access to Credit: Cooperatives can secure loans more easily than individual small farmers.
- Shared Resources: Farmers can share expensive equipment and facilities they couldn't afford individually.
2. Knowledge and Technology Transfer:
- Training and Education: Cooperatives provide training in modern farming techniques and technologies.
- Information Sharing: Farmers share experiences and solutions to common problems.
- Access to Extension Services: Cooperatives can collectively access government extension services more effectively.
- Adoption of New Technologies: Easier to introduce and adopt new technologies collectively.
3. Risk Reduction and Social Benefits:
- Risk Sharing: Collective action spreads risks among members (price fluctuations, crop failures).
- Social Support: Creates community among farmers facing similar challenges.
- Political Voice: Cooperatives give small farmers collective voice in policy discussions.
- Sustainable Practices: Easier to implement sustainable agricultural practices collectively.
