Crop Husbandry: JAMB Agricultural Science Questions, Answers & Notes

What Crop Husbandry covers in the JAMB Agricultural Science syllabus

Crop husbandry is the management and care of crops from planting to harvesting. Operations include raising seedlings in a nursery then transplanting them, planting/sowing, thinning (removing surplus seedlings for correct spacing), weeding (removing weeds that compete for water, nutrients, light and space), fertiliser application, irrigation, staking (supporting climbers like yam), earthing up/moulding (piling soil for support and tuber growth), pest and disease control, and timely harvesting (wrong timing reduces quality and causes losses). Crops are classified by use — food crops (maize, rice, yam) and cash crops (cocoa, rubber, cotton) — and by type: cereals/grains (maize, rice, millet), legumes/pulses (cowpea, groundnut, soybean — fix nitrogen) and tubers/roots (yam, cassava, cocoyam). Good husbandry gives healthy crops and high yields.

For Crop Husbandry, JAMB expects you to be able to:

• Describe crop husbandry operations from planting to harvesting
• Explain nursery, transplanting, thinning, weeding, staking, earthing up
• Classify crops (food/cash; cereals, legumes, tubers) and stress timely harvest

Key facts & revision notes: Crop Husbandry

These are the recurring points our Crop Husbandry questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• Crop husbandry is the management and care of crops from planting through to harvesting.
• Planting (sowing) is placing seeds or planting materials in the soil to grow.
• Weeding is the removal of weeds that compete with crops.
• Fertiliser application supplies nutrients to crops to boost growth and yield.
• Thinning removes surplus seedlings so remaining plants have the right spacing.
• Transplanting moves raised seedlings from a nursery to the main field.
• Earthing up (moulding) piles soil around the plant base for support and better tuber development.
• Staking provides sticks/support for climbing crops like yam and tomato.
• Harvesting is the gathering of mature crops from the field.
• A nursery is used to raise young seedlings before they are transplanted to the field.
• Irrigation is the artificial application of water to crops.
• Weeds compete with crops for water, nutrients, light and space, reducing yield.
• maize, rice, yam) are grown mainly for food.
• cocoa, rubber, cotton) are grown mainly for sale and export.
• Maize, rice and millet are cereal (grain) crops.
• Cowpea, groundnut and soybean are legumes (pulses), rich in protein and fixing nitrogen.
• Yam, cassava and cocoyam are tuber/root crops.
• Harvesting too early or too late reduces quality and can cause losses.
• Good husbandry (planting, weeding, fertilising, pest control, timely harvest) gives healthy crops and high yield.
• A typical sequence is land preparation → planting → weeding/fertilising → harvesting.

Worked examples

Three Crop Husbandry questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How Crop Husbandry is tested in JAMB Agricultural Science

Our Crop Husbandry bank holds 20 questions (3 easy, 15 medium, 2 hard). JAMB Agricultural Science typically returns to Crop Husbandry year after year, so steady practice on this topic is high-value revision. Questions are multiple-choice with four options, and at UTME pace you get roughly 40 seconds each — which is why timed practice matters.

How to answer Crop Husbandry questions

Work the stem first and predict the answer before you look at the options; then eliminate the ones that contradict the key facts above. Watch for “which is not…”, “all of the above” and “except” style stems, which are where rushed candidates lose easy marks on Crop Husbandry. If a calculation or a precise definition is involved, work it from first principles rather than guessing from a half-remembered rule. When two options look right, re-read the stem for the qualifier that separates them — JAMB rarely repeats an option by accident. If you are still unsure, eliminate the two weakest choices to lift your odds, flag the question, and move on; never burn a full minute on one Agricultural Science item when the exam gives you about forty seconds each. Then come back to flagged questions with whatever time remains. The single most reliable way to get faster at Crop Husbandry is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Crop Husbandry

The errors that cost marks on Crop Husbandry are usually careless rather than conceptual: misreading a negative stem, confusing two similar terms, or rushing a definition you actually know. Candidates also over-rely on “expo” and last-minute cramming instead of understanding the topic — which fails the moment JAMB rephrases a familiar idea. Treat every option as a claim to be checked against the facts above, keep your working tidy for any calculation, and don’t change a considered answer on a hunch. Above all, revise Crop Husbandry actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.
