Question 1 Report
Which of the following is a day-to-day record of work on a farmer's farm?
Answer Details
The day-to-day record of work on a farmer's farm is called a "labour diary." This record is used to keep track of the work done on the farm each day, including tasks performed, hours worked, and the number of workers involved. It is an important tool for the farmer to monitor the progress of work and ensure that tasks are completed on schedule. The other options listed - crop yield book, farm inventory, produce account, and profit and loss account - are all different types of records that a farmer might keep, but they do not specifically track the day-to-day work on the farm.
Question 2 Report
The desirable characteristics of forage crops include the following except
Answer Details
Forage crops are plants that are primarily grown to feed animals. They are a crucial source of nutrients for animals such as cows, sheep, goats, and horses. When selecting forage crops, farmers look for certain desirable characteristics that can ensure maximum yield and good nutrition for their animals. Palatability refers to the taste and smell of the forage crop, which affects whether animals will eat it or not. Dependability refers to the ability of the forage crop to produce consistent yields, even under variable environmental conditions. High yield is another important characteristic that ensures that there is enough forage to feed the animals. Resistance to trampling is also a desirable characteristic because animals may walk over the forage crop, which can damage or destroy it. On the other hand, poor reproductive ability is not a desirable characteristic for forage crops. This is because forage crops are typically harvested before they can produce seeds, so their reproductive ability is not important. Instead, farmers look for plants that produce a lot of biomass and are able to regrow quickly after harvest. Therefore, "poor reproductive ability" is the characteristic that is not desirable among forage crops.

Question 9 Report
Which of the following is not an effect of burning on the soil?
Answer Details
The option that is not an effect of burning on the soil is "increasing the organic matter in the soil". Burning of vegetation, also known as bush burning, has negative effects on soil fertility and ecosystem in general. It reduces soil organic matter, exposes the soil to erosion, increases soil acidity, and can lead to the loss of beneficial soil microorganisms. Therefore, burning of vegetation is generally discouraged in agriculture and land management practices.
Question 10 Report
Low fibre and high energy feeds are classified as
Answer Details
Low fibre and high energy feeds are classified as "concentrates". Concentrates are feeds that are high in energy and low in fibre, with a low content of crude fiber, and include grains and oilseeds. They are used to supplement the diets of animals and are typically given in smaller amounts than roughages or basal feeds, which are high in fibre and low in energy. The main function of concentrates is to supply energy and protein to meet the animal's nutritional requirements. They can be used to supplement grazing or forage diets, or as the main source of nutrition in confinement feeding systems.

Answer Details
The part of the ruminant stomach from which digestive juices are secreted is the abomasum. The abomasum is also called the "true stomach" of the ruminant because it functions similarly to the monogastric stomach found in non-ruminant animals. In contrast, the rumen, reticulum, and omasum are specialized compartments of the ruminant stomach where fermentation of ingested food occurs, with the aid of microorganisms. The paunch is another name for the rumen.
Question 14 Report
the factors that can predispose animals to diseases include the following except
Answer Details
The question is asking which of the following is NOT a factor that can predispose animals to diseases. The correct answer is "immunity", as immunity is a protective factor that can prevent animals from contracting diseases, rather than a factor that can predispose them to diseases. In simple terms, the other options - poor housing, malnutrition, physical injuries, and unfavorable weather - can all weaken an animal's immune system and make them more susceptible to contracting diseases.
Question 15 Report

Answer Details
The process whereby rocks are broken down into small particles through both physical and chemical factors is known as weathering. Physical factors that cause weathering include temperature changes, wind, and water, while chemical factors include acid rain, oxidation, and plant roots. These factors work together to break down the rock into smaller particles that eventually form soil.
Question 16 Report
The process of meiosis in plants ensures the production of reproduction of reproductive cells with
Answer Details
The process of meiosis in plants ensures the production of reproductive cells with half the number of chromosomes of the parent plant. During meiosis, the cell undergoes two rounds of division, which results in the production of four haploid cells (cells with half the number of chromosomes). This is important for sexual reproduction, as it ensures that when the sperm and egg cells unite, the resulting offspring will have the correct number of chromosomes.
Question 17 Report
Which of the following is not a factor of improvement in breeding cattle?
Answer Details
The factor of improvement in breeding cattle refers to the traits that breeders aim to enhance through selective breeding. These traits include high milk yield, fast growth, disease resistance, and good temperament, among others. Among the options provided, bloat, night blindness, milk fever, infertility, and anemia are all health conditions that can negatively impact the breeding potential of cattle. Bloat is a condition where the animal's stomach fills with gas and can be fatal if not treated quickly. Night blindness, caused by vitamin A deficiency, can reduce the animal's ability to see and lead to accidents or difficulty finding food. Milk fever is a metabolic disorder that can occur after calving and cause muscle weakness and decreased milk production. Infertility can affect both male and female cattle, and it can be caused by various factors such as disease, genetics, or poor nutrition. Anemia is a condition where the animal lacks sufficient red blood cells to transport oxygen to body tissues, which can cause weakness, fatigue, and decreased productivity. Therefore, the answer to the question is that "bloat" is not a factor of improvement in breeding cattle. Rather, it is a health condition that needs to be prevented or treated in order to maintain the health and productivity of the animal.
Question 18 Report
At which of the following ages are gilts normally mated?
Answer Details
Gilts are female pigs that have not yet given birth. Normally, they are mated between the ages of 8-12 months. At this age, they have reached sexual maturity and are able to conceive and carry a pregnancy to full term. Mating them earlier than 8 months may result in poor conception and litter sizes, while waiting until they are over 12 months may result in reduced fertility and increased risk of complications during pregnancy and farrowing. Therefore, the best age range for mating gilts is between 8 and 12 months.
Question 19 Report
The commonest method of land tenure in Nigeria is
Answer Details
The commonest method of land tenure in Nigeria is inheritance. Inheritance involves the transfer of land from parents to children, and it is a traditional method of land transfer that has been in existence for generations. Land is considered a family asset that is passed down from one generation to another, and it is governed by customary laws and practices. This method of land tenure is prevalent in rural areas where there is a strong attachment to family land and cultural practices. However, there are also other methods of land tenure in Nigeria, including lease, outright purchase, pledge, and state allocation, but they are not as common as inheritance.

Answer Details
Most farmers in Nigeria are hesitant in adopting new farming techniques because they are poor and cannot afford to take risks. This is because trying out new techniques may involve additional expenses and there is no guarantee of success. Many farmers in Nigeria live on subsistence farming and their income may not be sufficient to cover their basic needs, let alone to invest in new technologies. Additionally, they may not have access to credit facilities to support their farming activities. Therefore, they tend to stick to traditional farming techniques that they are familiar with and have been using for generations.
Question 24 Report
The most important limitation of agricultural mechanization is
Answer Details
The most important limitation of agricultural mechanization is small holdings. Agricultural mechanization requires significant capital investment in machinery and equipment, and it is more economical when practiced on large-scale farms. Small-scale farmers, who often have limited resources and land, may find it difficult to invest in such equipment. As a result, they may not be able to enjoy the benefits of mechanization, such as increased productivity, efficiency, and reduced labor costs.
Question 25 Report
The cross-section of a segment of soil showing the horizons or layers is known as the soil
Answer Details
The correct answer is "profile". A soil profile is a vertical section of the soil, from the surface down to the parent material, that displays a sequence of soil layers or horizons. These layers are differentiated from each other by their physical, chemical, and biological properties, and are used to study and classify soils. A soil profile is an important tool for understanding soil characteristics, such as soil structure, texture, depth, and fertility, and for identifying soil management practices that can be used to improve soil health and productivity.

The expression of a gene in the phenotype irrespective of whether the cell is homozygous or heterozygous is known as
Answer Details
The expression of a gene in the phenotype irrespective of whether the cell is homozygous or heterozygous is known as dominance. In genetics, dominance is a concept that describes how some alleles (versions of a gene) are expressed over others. If one allele is dominant, it will be expressed in the phenotype even if it is paired with a different allele that is recessive. This means that the presence of a dominant allele can mask the expression of a recessive allele in the phenotype. Dominance can be complete, where the dominant allele completely masks the expression of the recessive allele, or it can be partial, where the dominant allele only partially masks the expression of the recessive allele.
Question 31 Report

Question 35 Report
The average seed rate for maize is 25 kg per hectare. Allowing for a seed wastage of 5 per cent.How many kilogram of seeds would be required in planting 10 hectares of farmland?
Answer Details
The average seed rate for maize is 25 kg per hectare, which means 25 kg of maize seeds are required to plant 1 hectare of farmland. Now, to plant 10 hectares of farmland, we need to multiply the seed requirement for 1 hectare by 10. So, Seed requirement for 10 hectares = 25 kg/ha x 10 ha = 250 kg However, we also need to account for the seed wastage of 5%. This means that 5% of the total seed requirement will be wasted, and we need to add this to the original requirement. Seed wastage = 5% of 250 kg = (5/100) x 250 kg = 12.5 kg Total seed requirement with wastage = 250 kg + 12.5 kg = 262.5 kg Therefore, the answer is 262.5 kg, which is option E.
Question 36 Report
Thrips cause serious mechanical damages to crops by their
Answer Details
Thrips cause serious mechanical damages to crops by their feeding activities on flowers, leaves, and fruits. Thrips are small insects that feed on the surface of plants by piercing and sucking the sap out of the cells. This can cause deformities, stunted growth, discoloration, and even death of the plants. Thrips also scrape the surface of the plants with their mouthparts, which can create scarring, silvering, or bronzing of the leaves. These damages can reduce the quality and quantity of the crop yield, and can also make the plants more susceptible to secondary infections by fungi and bacteria.
Question 37 Report
The growing of both forest and agricultural crops on the same piece of land is termed
Answer Details
The term used to describe the growing of both forest and agricultural crops on the same piece of land is "taungya system". This is a type of agroforestry system in which farmers establish and maintain agricultural crops in the understory of a forest while the forest trees are still growing. The agricultural crops are typically planted in the forest during the first few years of its establishment and are later harvested as the forest matures. This system is commonly used in tropical regions to provide both food and income for farmers while also promoting forest conservation and management.

Answer Details
Peasant farmers sell almost all their produce immediately after harvesting because of inadequate storage facilities. They do not have proper storage facilities to preserve their produce, and stored produce may be lost to pests, lose their quality or may not fetch high prices in the market. Additionally, the commonest method of land tenure in Nigeria is communal landholding, and peasant farmers may not have exclusive rights to the land they farm. As a result, they may not have the resources to invest in storage facilities. Therefore, they choose to sell their produce immediately after harvest to avoid losses due to poor storage.
Question 41 Report
The best method(s) of regulating fish capture is/are
Answer Details
The best method(s) of regulating fish capture is/are quota and mesh-size control. Quotas refer to the limits set on the amount of fish that can be caught during a particular period, while mesh-size control refers to the use of fishing nets with a specific mesh size to prevent catching undersized or juvenile fish. These methods aim to maintain sustainable fishing practices by ensuring that fish populations are not overexploited or depleted. Gill netting and electro-fishing, active netting, and passive netting can lead to unintended bycatch and harm to non-target species. The beach seine method is also known to have negative impacts on the environment and other marine organisms. Therefore, quota and mesh-size control are considered the best methods for regulating fish capture.

Answer Details
It is best to plant a mixture of grasses and legumes in the establishment of pastures. This is because grasses and legumes complement each other in terms of nutrient content, growth habit, and ecological requirements. Legumes have the ability to fix atmospheric nitrogen, which is important for the growth of both grasses and legumes. Additionally, the legumes provide protein-rich forage for livestock, which can improve their productivity. On the other hand, grasses provide the bulk of the forage and can help to reduce weed growth by shading out weed seeds. Therefore, a mixture of grasses and legumes is ideal for sustainable pasture management.
Question 54 Report
Rhizobium supplies nitrogen to leguminous plants by
Answer Details
Rhizobium is a type of bacteria that lives in the root nodules of leguminous plants. It is able to fix atmospheric nitrogen, which means it can convert nitrogen gas from the air into a form of nitrogen that plants can use. This process of nitrogen fixation is very important for leguminous plants because it allows them to obtain nitrogen without having to rely on external sources such as fertilizers. The nitrogen that Rhizobium supplies to the plant is in the form of ammonium ions which the plant can absorb and use to synthesize amino acids, proteins, and other important compounds. So, the correct answer is "fixing atmospheric nitrogen".
Question 55 Report
Why should a seed-producing farmer spray an insecticide on his crops only when the bees are not around?
Answer Details
A seed-producing farmer should spray insecticides on his crops only when the bees are not around because bees are important for pollination of his crops. Bees are responsible for transferring pollen from male flowers to female flowers, which leads to the fertilization of the plant and the production of seeds. If the insecticide is sprayed when the bees are around, it may kill them or deter them from visiting the flowers, which would negatively impact the pollination process and ultimately reduce the yield of the crop. Therefore, it is important for farmers to time their insecticide application carefully and avoid spraying when bees are present. This helps to ensure that the crops receive adequate pollination and that the yield is maximized.

Question 63 Report
Write short notes on the following: (a) Selective exploration; (b) Deforestation; (c) Regeneration (d) Afforestation
(a) Selective exploration refers to the process of extracting resources from an area by selectively removing only certain trees or other natural resources, while leaving the rest of the area undisturbed. This is commonly used in forestry and mining operations to minimize environmental damage and ensure sustainability.
(b) Deforestation is the process of clearing forests and trees on a large scale, usually to make room for agriculture, urbanization, or other forms of human development. Deforestation has significant environmental impacts, including soil erosion, loss of biodiversity, and climate change.
(c) Regeneration refers to the natural regrowth and recovery of an ecosystem after it has been damaged or disturbed. This can happen after a natural disaster, such as a forest fire or hurricane, or as a result of human activities like logging or mining. Regeneration is important for maintaining ecosystem health and biodiversity.
(d) Afforestation is the process of planting trees in an area where there was no previous forest cover. Afforestation can help combat climate change by sequestering carbon dioxide from the atmosphere, as well as provide habitat for wildlife, protect soil from erosion, and improve air and water quality.

Question 65 Report
Discuss rinderpest disease of livestock under the following sub-headings: (a) Causal organism; (b) Transmission c) Symptoms (d) Effects and economic importance (e) Control
Here's the text converted to HTML with important points bolded:
```html
(a) Causal organism: Rinderpest is caused by a virus called the rinderpest virus, which belongs to the Paramyxoviridae family.
(b) Transmission: The virus is highly contagious and is transmitted through contact with infected animals, their bodily fluids or excretions, and contaminated equipment or surroundings.
(c) Symptoms: Rinderpest has an incubation period of about 3-9 days, after which the animal starts to exhibit symptoms such as fever, loss of appetite, nasal and ocular discharges, diarrhea, and severe dehydration. The animal may also develop sores in the mouth and on the skin. In the later stages of the disease, the animal may show neurological signs such as paralysis and convulsions.
(d) Effects and economic importance: Rinderpest is a highly fatal disease that can wipe out entire herds of cattle, buffalo, and other cloven-hoofed animals. It has caused devastating losses in the past, leading to famine and poverty in many regions of the world. The disease has also had a significant impact on the economies of affected countries, reducing the availability of meat, milk, and draft power.
(e) Control: The most effective way to control rinderpest is through vaccination. Mass vaccination campaigns have been successful in eradicating the disease from many parts of the world. Other control measures include quarantine of infected animals, movement restrictions, and disinfection of contaminated equipment and surroundings.

Describe briefly the economic importance and the control measures of the following: (a) Stem borers of cereal, (b) Grain weevils of stored produce: (c) Cotton stainer; (d) Cassava mealy bug
(a) Stem borers of cereal: Stem borers are a group of insects that cause significant economic losses to cereal crops such as maize, rice, and sorghum. They bore into the stems of these plants and feed on the vascular tissues, causing stunting, wilting, and even death of the plants. This can result in reduced yields and quality of the affected crops. Control measures include the use of resistant varieties, cultural practices such as crop rotation, and the application of insecticides.
(b) Grain weevils of stored produce: Grain weevils are a common pest of stored grains such as maize, rice, and wheat. They feed on the kernels of these grains, reducing their quality and making them unsuitable for consumption or sale. Control measures include proper storage techniques such as drying and fumigation, as well as the use of insecticides.
(c) Cotton stainer: Cotton stainers are insects that feed on cotton plants and stain the fibers with a reddish-brown color, reducing the value and marketability of the cotton. They also reduce yields by damaging the developing bolls. Control measures include the use of resistant varieties, cultural practices such as crop rotation and weed control, and the application of insecticides.
(d) Cassava mealy bug: Cassava mealy bug is a serious pest of cassava, a staple crop in many African countries. It feeds on the leaves and stems of cassava, causing stunting and reduced yields. Control measures include the use of resistant varieties, cultural practices such as intercropping with legumes, and the application of insecticides. In addition, the introduction of natural enemies such as parasitic wasps has been successful in controlling the pest in some areas.
