Crop Production Flashcards

Flashcards for reviewing key concepts related to crop production, including greenhouse management, fertilizers, and pest control.

Glasshouses and Polythene Tunnels

Structures used to increase the yield of certain crops by controlling environmental factors.

Increased Carbon Dioxide and Temperature (in Glasshouses)

Lead to enhanced photosynthesis, increasing crop yield.

Fertilizer

Used to increase crop yield by providing essential mineral ions to plants.

Pest Control

Managing pests to prevent damage to crops, including methods like pesticides and biological control.

Lamps in Greenhouse

Provide light for photosynthesis, especially during times of year with less natural light.

Heater and Ventilation Flaps

Used to maintain a specific temperature range for optimal photosynthesis.

Sprinkler System

Used to water plants.

Charcoal Burning (in Greenhouses)

Produces carbon dioxide to enhance photosynthesis.

Fans in Greenhouses

Prevent excessively high temperatures that could denature plant proteins.

Grow-Bulbs

Emit high levels of red and blue light to promote photosynthesis.

Selective Breeding

Use plants that have been selectively bred over many generations to improve crop yields.

Thermostatically Controlled Heater

Maintains optimal temperature for plant enzyme action.

Hydroponics

Plants do not grow in soil in this system.

Mini Bee Hives (in Greenhouses)

Used to pollinate plants.

Computer Controlled Technology

Takes care of environmental factors within the greenhouse.

Good Bugs vs. Bad Bugs

Good bugs are beneficial insects; bad bugs are pests that damage crops.

Plant Roots (in Sterilized Fibre / Ceramic Beads)

Reduces risk of soil-borne diseases.

Hydroponic Cultivation

Useful where soil quality is poor or space is limited.

Fertilizers

Increase key nutrients in the soil, leading to larger and healthier crop plants.

Pesticides

Kill off unwanted insects and weed species, reducing damage and competition.

Mineral Ions

Replaced by fertilizers to ensure continuous crop growth.

Organic Fertilizers

Farmyard manure and compost.

Pests

Insects and other animals that can damage crops by eating them.

Weeds

Outcompete crop plants for space, water, and soil nutrients.

Fungi

Infect crop plants and spread disease.

Insecticides

Kill insects.

Herbicides

Kill weeds.

Fungicides

Kill fungi.

Biological Control

Introducing a species to prey on the pest species.

Parasitic Wasps

Control whitefly in glasshouse tomato crops.

Pesticides

Fast-acting, broad-spectrum control.

Biological Control

Environmentally friendly and sustainable.

Biological Control Disadvantages

Slower to act, specialized for specific pests
