Question 1 Report
Which of the following crop is tolerant to both poor and rich friable soils?
Answer Details
Cassava is the crop that is tolerant to both poor and rich friable soils. Cassava is a hardy crop that can grow well in poor soils with low nutrient levels as well as in rich, fertile soils. It is also tolerant to drought and can survive in areas with irregular rainfall patterns. Because of its ability to grow in diverse soil conditions, cassava is an important food crop in many developing countries.
Question 3 Report
In which of the following ways are metamorphic rocks formed?
Answer Details
Metamorphic rocks are formed through chemical changes caused by heat and pressure. When rocks are subjected to high temperatures and pressures, the minerals and textures within them can change. This process is called metamorphism. Metamorphic rocks are formed from pre-existing rocks, which can be igneous, sedimentary, or even other metamorphic rocks. During metamorphism, the rocks are subjected to intense heat and pressure, which can cause the minerals in the rock to change. This can result in changes to the color, texture, and overall appearance of the rock. Some common examples of metamorphic rocks include marble, slate, and gneiss. In contrast, the other options listed involve different processes for rock formation. Physical disintegration of igneous rocks and alternative layering of particles of sedimentary and igneous rocks are processes involved in the formation of sedimentary rocks, while the combination of igneous and sedimentary rocks can result in the formation of hybrid rocks known as igneous-sedimentary rocks. Biological change of original rock, on the other hand, is not a common process in rock formation.

Ginger rhizomes are usually peeled and grated, sliced, or ground to be used in various dishes or as a herbal remedy for different ailments.
Question 7 Report
Natural immunity against diseases is conferred on the newly born animal through
Answer Details
Natural immunity against diseases is conferred on the newly born animal through feeding with colostrum. Colostrum is the first milk produced by female mammals immediately after giving birth. It contains high levels of antibodies, which are proteins that fight against diseases and infections. When a newborn animal drinks colostrum, the antibodies in the colostrum are absorbed into its bloodstream, providing it with natural immunity against a wide range of diseases. This immunity is temporary and gradually fades away over time, but it is crucial in protecting the animal during its early life. Vaccination, sanitation, and administration of antibiotics and drugs can also help to protect animals against diseases, but they do not confer natural immunity like colostrum does.
Question 8 Report
Which of the following is not a pasture legume?
Answer Details
The correct option is (D) andropogon. Andropogon is not a pasture legume but a grass species. Pasture legumes are important forage crops that are high in protein, digestibility, and minerals and help to improve soil fertility. Examples of pasture legumes include pueraria, calopogonium, centrosema, and stylosanthes.
Question 9 Report
Agricultural production in West Africa can be improved by the following except
Answer Details
The option that does not improve agricultural production in West Africa is "continued adoption of the communal land holding system". The communal land holding system refers to a traditional land tenure system in which land is owned and managed by a community rather than individual landowners. However, this system has been identified as a major constraint to agricultural development in West Africa because it limits individual farmers' incentives to invest in their land and improve their productivity. On the other hand, the other options listed can improve agricultural production in West Africa. The ability of farmers to purchase modern farm implements can help to increase efficiency and productivity on the farm. Expansive irrigation of farmlands can help to mitigate the effects of drought and increase crop yields. Adoption and proper application of tested findings of agricultural research can help farmers to adopt improved practices and technologies that can enhance their productivity. Adequate supply of improved seeds and livestock to farmers can help to increase crop and livestock yields, leading to improved livelihoods and food security. Therefore, continued adoption of the communal land holding system is the option that does not improve agricultural production in West Africa.
Question 11 Report
Prolonged application of ammonium sulphate fertilizer on a given soil can lead to the
Answer Details
Prolonged application of ammonium sulphate fertilizer on a given soil can lead to an increase in soil acidity. This is because ammonium sulphate fertilizer contains ammonium ions that can be converted to nitrate by soil bacteria. During this process, hydrogen ions are released, leading to an increase in soil acidity. This increased acidity can damage soil structure and reduce the availability of nutrients for plants. Additionally, some crops may not grow well in acidic soil conditions. Therefore, it is important to carefully manage the application of ammonium sulphate fertilizer to prevent negative effects on soil quality.

Answer Details
A moistened soil sample that can be moulded into a smooth continuous ring is a characteristic of a soil with a significant clay content. This is because soils with higher clay content have the ability to hold water and maintain soil structure even when moistened. Clay particles are very small and have a large surface area, so they can hold a lot of water and nutrients. Therefore, a soil with a high clay content will feel sticky when wet and can be easily moulded, indicating its cohesive properties. So, the correct option is heavy clay.

Answer Details
The option that is not correct about market in agriculture is "a place for social activities". While it is true that markets may provide opportunities for social interactions, the primary purpose of a market is to facilitate buying and selling activities. Markets in agriculture can be physical or virtual and may involve various types of transactions, including spot sales, forward contracts, and futures contracts. The market brings together buyers and sellers, who negotiate prices and quantities, and determine the terms of the transaction. In this way, markets play an important role in the economy by facilitating the exchange of goods and services between buyers and sellers.
Question 19 Report
Which of the following is a primary product of forest trees?
Answer Details
One primary product of forest trees is timber, which is also known as wood or lumber. Timber is the wood that is harvested from trees and used for construction, furniture, and many other purposes. After the trees are harvested, they are cut into different sizes and shapes, depending on their intended use. For example, larger trees can be used for building homes and furniture, while smaller trees can be used for paper and other products. While paper, particle board, cardboard, and pulp can all be made from wood, they are not considered primary products of forest trees because they require additional processing and manufacturing steps to turn the wood into these products. In contrast, timber is the raw product that comes directly from the trees and can be used for many different purposes.
Question 20 Report
What is the effect of applying pressure on a ring inserted through the nostril of a bull?
Answer Details
The application of pressure on a ring inserted through the nostril of a bull is known as bull nose ringing. It is believed to have a calming effect on the bull, making it more manageable and easier to handle. The ring applies pressure on sensitive nerves in the nostril, which helps to control the bull's movements and reduces its resistance. This makes it easier for farmers to handle and transport the animal. The practice is not without controversy, however, as some animal welfare groups argue that it can cause unnecessary pain and discomfort to the bull.
Question 21 Report

Answer Details
The farm animal whose skin or hide cannot be used for leather production is the chicken. This is because the skin of a chicken is too thin and not suitable for leather production, unlike the skin of other animals such as goats, sheep, cattle, and pigs. While chickens are typically raised for their meat and eggs, their skin is not a viable source for leather production.
Question 22 Report
The stages of life cycle of locust are
Answer Details
The correct answer is: egg-nymph-adult. Locusts undergo incomplete metamorphosis, which means that they do not have a pupal stage. Instead, they go through three stages: egg, nymph, and adult. The life cycle of a locust begins when a female locust lays her eggs in soil. After a period of incubation, the eggs hatch into nymphs, which look like small versions of adult locusts but lack wings. Nymphs go through several molts as they grow and develop, becoming larger and more mature with each molt. Eventually, they reach adulthood and develop wings that enable them to fly and migrate long distances in search of food and suitable breeding sites. The adult stage is the final stage of the locust life cycle, during which time the insects mate, lay eggs, and die. Depending on environmental conditions, the entire life cycle of a locust can take anywhere from several weeks to several months.
Question 24 Report
The planting depth of rice grain is about
Answer Details
The planting depth of rice grain is about 2-4 cm. This means that when planting rice, the seeds should be buried in the soil at a depth of 2-4 cm. This is the recommended depth for optimum growth and development of rice plants. Planting at a depth that is too shallow or too deep can lead to poor germination and low yield. Therefore, it is important to ensure that the planting depth is appropriate when planting rice.

Question 26 Report
land use is influenced by the following except
Answer Details
Land use is the way in which human beings use land for various purposes such as agriculture, forestry, mining, settlement, recreation, among others. Several factors influence land use, including population density, population growth, climatic conditions, topography, and fallowing. However, the question asks for the factor that does not influence land use. Therefore, the answer would be "fallowing," which is a land management practice that involves leaving the land uncultivated for some time to allow it to regenerate and improve its fertility. Fallowing is not an influence on land use but rather a practice that farmers use to improve soil fertility and manage land.
Question 27 Report
Which of the following plant parts or modification is not suitable for propagation of pastures?
Answer Details
The plant part or modification that is not suitable for propagation of pastures is leaves. Leaves are not typically used for propagation of pastures because they do not contain the necessary structures for growth and development into a new plant. While leaves do play an important role in photosynthesis and nutrient storage, they are not able to develop into a new plant on their own. Stem cuttings, seeds, stolons, and rhizomes are all suitable for propagation of pastures. Stem cuttings can be taken from mature plants and rooted to form new plants. Seeds can be collected from mature plants and planted to produce new plants. Stolons and rhizomes are specialized stem structures that allow the plant to spread and form new shoots, making them ideal for propagation. In summary, leaves are not suitable for propagation of pastures, while stem cuttings, seeds, stolons, and rhizomes are all commonly used for this purpose.

Answer Details
Shellers are used to remove grains from cobs. This is usually done in crops such as maize, where the kernels are tightly attached to the cob. The process involves passing the maize cob through the shellers, which use a combination of mechanical and/or pneumatic force to separate the grains from the cob. The grains are then collected while the cobs are discarded as waste.
Question 32 Report
Which of the following is the reason for smoking fish?
Answer Details
The reason for smoking fish is to preserve it. Smoking is a traditional method of preserving fish that has been used for centuries. The process of smoking involves exposing the fish to smoke produced by burning wood or other materials. This smoke contains chemicals that inhibit the growth of bacteria and other microorganisms that cause spoilage. As a result, the fish can be stored for longer periods of time without refrigeration or other forms of preservation. Smoking also imparts a distinct flavor to the fish that is often considered desirable. The smoke and heat from the smoking process cause the fish to become dehydrated and partially cooked, which can enhance its flavor and texture. Therefore, the reason for smoking fish is to preserve it and enhance its flavor.

Therefore, the set of farm operations that can use electricity as a source of power is "processing, storage and extraction."
Question 35 Report
The assistance given to farmers by government in form of a reduction in price is generally referred to as
Answer Details
The assistance given to farmers by the government in the form of a reduction in price is generally referred to as a subsidy. A subsidy is a form of financial assistance given by the government to support a particular activity or industry, in this case, agricultural production. In agriculture, subsidies are given to farmers to help them reduce their production costs by providing financial support for inputs like fertilizers, seeds, and pesticides. This helps farmers to increase their yields and profits, which in turn leads to an increase in the supply of food and a reduction in the price of food in the market. Moreover, subsidies encourage farmers to adopt modern technology and improve their farming practices. By reducing the cost of inputs, farmers can afford to invest in new equipment and technologies that improve the efficiency of their farming operations. In summary, a subsidy is the assistance given to farmers by the government in the form of a reduction in price. It is a form of financial support that helps farmers to increase their production and income, adopt modern technologies and practices, and ultimately contributes to an increase in the supply of food and a reduction in the price of food in the market.
Question 36 Report
The signs of approaching parturition include the following except
Answer Details
Parturition refers to the process of giving birth in animals. There are several signs that indicate that an animal is approaching parturition. However, one of the options listed is not a sign of approaching parturition. 1. Preparation of nests by the dam: Some animals, such as rabbits and rodents, will prepare a nest for their young before giving birth. This behavior is an indication that parturition is imminent. 2. Swelling of the vulva: The vulva is the external opening of the reproductive tract in female animals. As parturition approaches, the vulva may become swollen and more prominent. 3. Enlargement of the mammary glands: The mammary glands in female animals produce milk for their young. As parturition approaches, the mammary glands may become enlarged and begin to produce colostrum, a nutrient-rich fluid that provides essential antibodies to the newborn. 4. Mounting of other animals: The mounting behavior in animals, such as horses or cows, is an indication that they are in heat and ready for breeding. This behavior is not a sign of approaching parturition. 5. Loss of appetite: Some animals may experience a decrease in appetite as parturition approaches. This can be due to discomfort or changes in hormone levels. In conclusion, the sign that is not an indication of approaching parturition is mounting of other animals. The other signs listed, including preparation of nests, swelling of the vulva, enlargement of the mammary glands, and loss of appetite, can be useful in predicting when an animal is about to give birth.

Answer Details
The damage to the stem of maize plants resulting in hollowness and lodging is most likely caused by stem borers. Stem borers are insects that bore into the stem of the plant and feed on the inner tissues, leading to hollowness and weakness of the stem. As a result, the stem is unable to support the weight of the plant, causing lodging. This is a common problem in maize production and can significantly reduce yields if not controlled.
Question 39 Report
Which of the following statement on ration is not correct?
Answer Details
The statement that is not correct is "finisher ration is for feeding chicks from day-old to market size." Finisher ration is not used to feed chicks from day-old to market size. Instead, it is used to feed growing birds that are close to reaching their market size or maturity. Finisher ration is typically fed to broilers after they have been on a starter and grower ration. Finisher ration is formulated with a lower protein content and higher energy content compared to starter and grower rations. This helps the birds to gain weight and reach their market size more efficiently. The duration of feeding finisher ration depends on the breed of bird and the market weight they are being raised for. In summary, finisher ration is not used to feed chicks from day-old to market size, but instead is used to feed growing birds that are nearing their market weight or maturity.

Answer Details
Using an N'dama bull to mate with a Muturu cow is an example of cross-breeding. Cross-breeding involves mating two different breeds of animals to produce offspring with desirable traits from both breeds. In this case, the N'dama bull and Muturu cow are two different breeds of cattle. By mating them, the offspring would have characteristics of both breeds, such as disease resistance from the N'dama and heat tolerance from the Muturu. In contrast, inbreeding involves mating closely related individuals, which can lead to an increased risk of genetic defects and other problems. Selection involves choosing individuals with desirable traits to breed, while introduction involves bringing in new breeds of animals to a population. Artificial insemination involves using technology to fertilize eggs outside of the animal's body and then implanting them into the female animal.

Answer Details
Land is considered to be an essential factor in agricultural production because it is the natural resource where crop, fisheries, and livestock production take place. Agriculture involves the cultivation of crops, rearing of livestock, and fish farming, all of which are carried out on land. Agricultural land provides a habitat for crops and animals to grow and reproduce. Moreover, agricultural production cannot take place without land, as other factors of production such as labor, capital, and technology are useless without land. Although other resources can be substituted, land cannot be increased in quantity as it is a finite resource. Hence, land is a crucial resource for agricultural production and cannot be overlooked. In summary, land is an essential factor in agricultural production because it provides a physical space for the production of crops, fisheries, and livestock. Without land, agricultural production cannot take place, and other resources are rendered useless.
