The BGCSE Field Crop Production examination is a secondary-school agriculture qualification in The Bahamas, typically taken by students completing the senior years of the national curriculum. It suits candidates who want a grounding in practical crop husbandry, whether they intend to farm, work in agribusiness, or continue into agricultural or environmental studies. The BGCSE Field Crop Production 1256 study guide has 10 sections and about 4,054 words.
01Crop Biology: Classification, Structure and Function
Crop biology supplies the vocabulary for every later topic. Know the difference between monocotyledons (one seed leaf, parallel veins, fibrous roots, scattered vascular bundles, e.g.
325 words, about 2 min02Growth and Development: Stages, Hormones and Yield
Growth is an irreversible increase in size or mass; development is the sequence of stages. Learn the cereal sequence: germination, emergence, tillering (branching in grasses), stem elongation, booting, heading, flowering (anthesis), grain filling, physiological maturity.
340 words, about 2 min03Soils: Formation, Texture, Structure and Water
Know the soil profile: O (organic litter), A (topsoil, humus-rich), B (subsoil, accumulation), C (weathered parent material), R (bedrock). Describe the three soil particles - sand (large, drains fast, low water holding), silt (medium), clay (tiny, high water holding and nutrient exchange) - and read a textural triangle.
342 words, about 2 min04Soil Fertility and Plant Nutrition
Know the essential elements and their roles. Macronutrients : nitrogen (leaf growth, protein, chlorophyll), phosphorus (roots, energy transfer, early establishment), potassium (water regulation, stem strength, grain filling), calcium (cell walls), magnesium (chlorophyll centre), sulphur (proteins).
340 words, about 2 min05Land Preparation and Crop Establishment
Know the purposes of land preparation: clearing, loosening, levelling, incorporating residues, controlling weeds and creating a seedbed. Distinguish primary tillage (ploughing, ripping, subsoiling) from secondary tillage (harrowing, discing, levelling, rolling).
325 words, about 2 min06Crop Husbandry and Management Practices
This domain covers the routine decisions that turn a planted field into a crop. Know plant population and spacing (wider rows for maize and sunflower, closer for cereals and legumes), thinning , gap filling , weeding schedule , mulching , staking , pruning , earthing up , and ratooning .
353 words, about 2 min07Water Management and Irrigation
Know the soil water terms used in scheduling: field capacity , permanent wilting point , available water , infiltration , percolation and evapotranspiration (ET) . Understand irrigation scheduling - when to irrigate and how much - using feel-and-appearance tests, tensiometers, evaporation pans and crop water-use tables.
331 words, about 2 min08Crop Protection: Pests, Diseases and Weeds
Know the categories: insect pests (chewing, piercing-sucking, boring), diseases (fungal, bacterial, viral, nematode), weeds (grasses, sedges, broadleaves) and vertebrate pests . Understand the disease triangle - susceptible host, virulent pathogen and favourable environment - and the pest management pyramid : prevention, cultural control, biological control, mechanical control, chemical control.
342 words, about 2 min09Harvesting, Post-Harvest Handling and Storage
Know maturity indices : physiological maturity (black layer in maize), moisture content, days to maturity, colour change, and firmness. Understand harvest methods - hand, mechanical - and the importance of harvesting at the right moisture.
344 words, about 2 min10Farm Tools, Machinery and Safety
Know hand tools and their uses: hoe (weeding, ridging), mattock, cutlass/machete (clearing), rake (levelling, gathering), fork (lifting, turning manure), dibber (planting holes), watering can, knapsack sprayer, secateurs, pruning saw, wheelbarrow. Know the parts of a plough (share, mouldboard, landside, coulter, beam), a harrow (disc or spike), a planter (seed hopper, metering unit, furrow opener, covering device) and a sprayer (tank, pump, lance, nozzle, filter).
