BGCSE Field Crop Production 1256 is administered by the Botswana Examinations Council (BEC) for senior secondary students. The syllabus covers cereal and legume field crops, land preparation, soil fertility, pest and disease management, grain storage, and semi-arid water conservation in Botswana. BEC assesses it through written Paper 1256/01 (2 hours), practical Paper 1256/02 and moderated coursework; the 100 questions here are an English-language MCQ study adaptation rather than an official-format simulation.

Sample BGCSE Field Crop Production 1256 Practice Questions

Try these sample questions to review concepts for the BGCSE Field Crop Production 1256 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which field crop is widely regarded as the most drought-tolerant staple cereal grown in Botswana due to its deep root system and ability to enter dormancy during severe dry spells?
A.Maize (Zea mays)
B.Sorghum (Sorghum bicolor)
C.Wheat (Triticum aestivum)
D.Rice (Oryza sativa)
Explanation: Sorghum (Sorghum bicolor) has a dense, deep root system and a waxy leaf cuticle that reduces transpiration. It can temporarily halt growth during dry spells and resume when moisture becomes available, making it ideal for Botswana's semi-arid environment.
2What is the primary agronomic benefit of incorporating grain legumes like cowpeas (dinawa) into a crop rotation with cereal crops in Botswana?
A.Legumes deplete soil moisture to prevent waterlogging
B.Legumes fix atmospheric nitrogen through symbiotic Rhizobium bacteria
C.Legumes act as host plants for cereal stalk borers
D.Legumes increase soil acidity to suppress all weed growth
Explanation: Grain legumes form a symbiotic association with root nodule Rhizobium bacteria that convert atmospheric nitrogen into plant-available nitrate forms. Rotated cereal crops benefit from residual soil nitrogen left by the legumes.
3Which localized sorghum cultivar developed in Botswana is known for its open panicle structure, medium height, and high yield under semi-arid conditions?
A.Segaolane
B.Golden Yellow
C.Kalahari Early
D.Sugar Drip
Explanation: Segaolane is a popular open-pollinated sorghum variety in Botswana characterized by an open panicle that reduces bird damage and mold, medium height, and stable yields under drought conditions.
4Which characteristic of pearl millet (lebelebele) allows it to produce grain even when the main stem is damaged by drought or pests?
A.Taproot extension
B.Tillering capacity
C.Stem elongation
D.Vining growth habit
Explanation: Pearl millet has a strong tillering ability, producing secondary shoots (tillers) from the base. If the primary shoot suffers stress or pest injury, side tillers can mature and produce harvestable grain heads.
5During groundnut (Arachis hypogaea) development, what is the name of the specialized stalk structure that elongates after fertilization and pushes the ovary into the soil for pod formation?
A.Stolon
B.Tiller
C.Peg (Gynophore)
D.Tendril
Explanation: After pollination and fertilization, the base of the ovary elongates into a geotropic stalk called a peg or gynophore. The peg grows downward into the topsoil where the fruit expands into a mature groundnut pod.
6Why is deep mouldboard ploughing carried out as a primary tillage operation before planting field crops in Botswana?
A.To compact the lower soil layer to retain runoff
B.To invert the soil, bury weed seeds, and loosen the root zone
C.To eliminate the need for fertilizer application
D.To decrease soil aeration and slow down organic matter decomposition
Explanation: Primary tillage with a mouldboard plough inverts the upper soil layer, buries crop residues and surface weed seeds, breaks hard soil crusts, and creates a loose, aerated root zone for crop establishment.
7What is a major disadvantage of broadcasting seed manually over a field compared to row planting using a mechanical planter?
A.Broadcasting requires more expensive tractor implements
B.Uneven seed depth and irregular plant spacing make weeding and harvesting difficult
C.Broadcasting always results in higher seed germination rates
D.Row planting requires twice as much seed per hectare
Explanation: Broadcasting scatters seed unevenly, leaving some seeds too shallow and others too deep. Irregular plant arrangements make mechanical inter-row cultivation and hand weeding inefficient.
8What general rule governs planting depth relative to crop seed size in field crop production?
A.Small seeds should be planted deeper than large seeds
B.Seeds should be planted to a depth equal to 50 times their diameter
C.Small seeds require shallow planting while larger seeds can be planted deeper
D.All field crop seeds must be planted at a uniform depth of 10 cm
Explanation: Small seeds (e.g. pearl millet, sorghum) have smaller food reserves (endosperm) and must be planted shallowly (2-4 cm) so seedlings reach light before energy is exhausted. Larger seeds (maize, groundnuts) have larger reserves and can emerge from deeper placement (5-7 cm).
9Which secondary tillage implement is primarily used to break up soil clods and smooth the seedbed after primary ploughing?
A.Subsoiler
B.Disc harrow
C.Mouldboard plough
D.Ridger
Explanation: A disc harrow is a secondary tillage tool used to pulverize large soil clods, destroy early weed flushes, and level the soil surface to prepare a fine seedbed for planting.
10Why is winter ploughing (ploughing immediately after harvest in autumn/winter) recommended for dryland crop fields in Botswana?
A.It warms the soil to trigger immediate winter seed germination
B.It captures late rain, conserves soil moisture, and buries over-wintering crop pests
C.It replaces the need for summer rainfall during the growing season
D.It sterilizes the soil by exposing subterranean bacteria to frost
Explanation: Winter ploughing opens up the soil to absorb late-season moisture, reduces moisture loss through weed transpiration, and exposes soil-dwelling insect pupae (like stalk borers) to predators and desiccation.
