Pasture and Forage Crops: JAMB Agricultural Science Questions, Answers & Notes

What Pasture and Forage Crops covers in the JAMB Agricultural Science syllabus

Pasture is land covered with grasses and legumes for grazing animals, and forage crops are plants grown mainly as livestock feed. Pasture is natural/native (growing naturally) or artificial/established (deliberately sown with selected species); natural pasture is improved by oversowing with better grasses/legumes. Common forages include grasses (Guinea grass, elephant grass) and legumes (Stylosanthes/stylo, Centrosema/centro) — legumes fix nitrogen (enriching soil, cutting fertiliser needs) and give protein-rich feed. Forage is preserved as silage (fermented, stored in a silo) or hay (dried). Good management includes controlled and rotational grazing (moving animals between paddocks so pasture recovers), cut-and-carry/zero grazing, fertilising and weed control, while overgrazing causes erosion and degradation. The aim is to feed livestock efficiently and cheaply.

For Pasture and Forage Crops, JAMB expects you to be able to:

• Define pasture and forage and distinguish natural and artificial pasture
• Identify forage grasses/legumes and preservation (silage, hay)
• Explain pasture management (rotational grazing, cut-and-carry) and the role of legumes

Key facts & revision notes: Pasture and Forage Crops

These are the recurring points our Pasture and Forage Crops questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• Pasture is land covered with grasses and legumes on which animals graze.
• Forage crops are grown mainly as feed for farm animals (livestock).
• Natural (native) pasture consists of plants growing naturally without being deliberately planted.
• Artificial (established) pasture is deliberately planted with selected forage species.
• Forage legumes like Stylosanthes (stylo) and Centrosema (centro) feed animals and fix nitrogen.
• Elephant grass, Guinea grass and Gamba grass are common forage grasses.
• Silage is forage preserved by fermentation in a silo (moist storage).
• Hay is forage preserved by drying (e.g.
• Pasture legumes fix nitrogen (enriching soil) and provide protein-rich, nutritious feed.
• Overgrazing (too many animals) removes vegetation, causing erosion and degraded pasture.
• Rotational grazing moves animals between paddocks so grazed pasture can recover.
• Good pasture management includes controlled grazing, fertilising, and weed/pest control.
• Cut-and-carry (zero grazing) involves cutting forage and feeding it to penned animals.
• Forage crops provide nutritious feed for livestock, supporting animal production.
• A silo is a structure used to store silage (fermented, preserved forage).
• Because legumes fix nitrogen, they reduce the need for nitrogen fertiliser on pasture.
• Oversowing natural pasture with improved legumes/grasses raises its quality and yield.
• Grazing pasture too early damages young regrowth and lowers future yield.
• Guinea grass is a forage/pasture crop; the others are food/cash crops.
• Pasture and forage crops aim to feed livestock efficiently and economically.

Worked examples

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

How Pasture and Forage Crops is tested in JAMB Agricultural Science

Our Pasture and Forage Crops bank holds 20 questions (9 medium, 11 hard). JAMB Agricultural Science typically returns to Pasture and Forage Crops 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 Pasture and Forage Crops 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 Pasture and Forage Crops. 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 Pasture and Forage Crops is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Pasture and Forage Crops

The errors that cost marks on Pasture and Forage Crops 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 Pasture and Forage Crops actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.
