Which of the following uses of land should be given more attention in Nigeria for self sufficiency in food production?
Answer Details
Establishment of agriculture and forestry should be given more attention in Nigeria for self-sufficiency in food production. Agriculture and forestry involve the cultivation of crops and the management of forests, respectively. Nigeria is blessed with fertile land and a favourable climate, which are ideal for agriculture and forestry. By establishing agriculture and forestry, Nigeria can increase its food production and achieve self-sufficiency in food supply. This will not only reduce the country's dependence on food imports but also create job opportunities for the people. The construction of roads, building of research centres, establishment of wildlife, and construction of fish ponds are also important, but the establishment of agriculture and forestry should be given more priority as it is essential for food security and economic growth.
Question 7 Report
Layers mash should contain a high percentage of
Answer Details
Layers mash should contain a high percentage of calcium. This is because calcium is a vital mineral that is essential for eggshell formation in poultry. Laying hens require a sufficient amount of calcium in their diet to lay eggs with strong, hard shells. Calcium deficiency in hens can lead to soft-shelled or shell-less eggs, which are prone to breakage and can cause health problems for the birds. Therefore, it is important to provide layers with a diet that is rich in calcium, typically provided in the form of calcium carbonate.

Answer Details
Rangeland management refers to the process of managing and conserving the natural resources of rangelands for sustainable use. The methods used in rangeland management include rotational grazing, good irrigation schedule, and roguing of pastures. Fertilizer application is also a management practice that can be used to improve soil fertility and increase forage production. However, overgrazing is not a method of rangeland management because it leads to the degradation of rangeland resources, such as soil erosion, loss of vegetation, and reduced biodiversity. Therefore, the answer is option A - Overgrazing.
Question 11 Report
The components of soil include the following except
Answer Details
Soil is a complex mixture of different components that are essential for plant growth. These components include living organisms, such as bacteria and earthworms, which help in decomposing organic matter and recycling nutrients. Moisture is also an important component of soil, as it provides water for plants to absorb through their roots. Mineral matter, such as sand, silt, and clay, make up the non-living part of soil and provide nutrients for plant growth. Humus is the organic matter in soil that comes from the decomposition of plant and animal remains. However, light is not a component of soil, as it is a form of electromagnetic radiation that does not physically make up the soil itself.

Answer Details
A miracidium is a larval stage of a liver fluke. The liver fluke is a parasitic flatworm that infects the liver of various mammals, including humans. The life cycle of the liver fluke involves several stages, including the miracidium, which is released from the eggs of the fluke and infects a snail intermediate host. After undergoing several more developmental stages in the snail, the fluke is released as a cercariae, which can infect the final host, such as a cow or a human, by penetrating the skin or being ingested.
Question 13 Report
Which of the following symptoms occurs when there is deficiency of iron and copper in livestock rations?
Answer Details
The symptom that occurs when there is a deficiency of iron and copper in livestock rations is anemia. Anemia is a condition where the body does not have enough red blood cells or hemoglobin, which are responsible for carrying oxygen to the body's tissues. Iron and copper are essential minerals that are required for the production of hemoglobin. A deficiency of these minerals can result in anemia, which can cause reduced growth rate and weakness in livestock. Rickets is a condition caused by a deficiency of vitamin D, which can result in weakened and deformed bones. Scaly skin and lameness are not typically associated with deficiencies of iron and copper.
Question 14 Report
The major advantage of drainage in agriculture is
Answer Details
The major advantage of drainage in agriculture is removing excess water from the soil. Drainage helps to prevent water-logging which can lead to a reduction in crop yield or even crop failure. When there is excess water in the soil, it displaces the air in the soil pores, leading to the death of plant roots due to lack of oxygen. Drainage helps to create a balance between water and air in the soil, which promotes healthy plant growth. Additionally, excess water in the soil can lead to the leaching of nutrients, making them unavailable to plants. Drainage can help to prevent this by allowing water to move through the soil, carrying nutrients to the root zone where they are needed.

Question 17 Report
The correct sequence of the components of a goat's stomach is
Answer Details
A goat's stomach has four compartments, which are the rumen, reticulum, omasum, and abomasum. The correct sequence of the components of a goat's stomach is rumen-reticulum-abomasum-omasum. This is because when a goat eats, the food goes into the rumen and reticulum, where it is fermented and partially digested. The food is then regurgitated and chewed again before being swallowed and sent to the omasum for further digestion and absorption of nutrients. Finally, the remaining digesta enters the abomasum, which is the true stomach, where it is mixed with acid and digestive enzymes to complete the process of digestion.
Question 19 Report
The mating of different breeds of animals is known as
Answer Details
The mating of different breeds of animals is known as cross-breeding. Cross-breeding involves mating individuals from different breeds, resulting in offspring that exhibit a combination of traits from each parent breed. This is often done to produce animals with desirable characteristics, such as increased milk or meat production, improved disease resistance, or better temperament. Cross-breeding is also important for genetic diversity and can help to prevent inbreeding depression.

The particle size of silt is
Answer Details
The particle size of silt is 0.002 mm - 0.02 mm. This means that silt particles are smaller than sand particles (which are 0.02 mm - 2 mm) but larger than clay particles (which are smaller than 0.002 mm). Silt particles are often considered ideal for soil fertility because they are small enough to increase soil porosity and water-holding capacity, but not so small that they easily compact and reduce soil aeration.
Question 22 Report
Which of the following types of labour is commonly used in peasant agriculture?
Answer Details
Peasant agriculture is typically characterized by small-scale farming operations with limited resources, which often rely on family labor as the primary source of work. Therefore, the type of labor that is commonly used in peasant agriculture is "family labor." Family labor involves the use of family members for various farming activities, such as planting, weeding, harvesting, and other related farm operations. In this type of labor, family members do not receive any salary or wages but rather share in the farm's profits or benefits. It is an essential component of peasant agriculture and helps to reduce labor costs, increase productivity, and ensure food security for the family.
Question 23 Report
A motorized sprayer was purchased at N2,000.0 and sold at N1,000.00 after 5 years. calculate the annual depreciation of the sprayer.
Answer Details
The annual depreciation of the sprayer can be calculated using the straight-line method of depreciation. This method assumes that the asset depreciates at a constant rate over its useful life. To calculate the annual depreciation, we need to first determine the depreciable value of the sprayer. Depreciable value is the difference between the cost of the asset and its salvage value (the amount for which it is sold at the end of its useful life). Depreciable value = Cost - Salvage value Depreciable value = N2,000.00 - N1,000.00 Depreciable value = N1,000.00 Since the sprayer was used for 5 years, its useful life is 5 years. Annual depreciation = Depreciable value / Useful life Annual depreciation = N1,000.00 / 5 Annual depreciation = N200.00 Therefore, the annual depreciation of the sprayer is N200.00.

Stoloniferous means that the grass produces horizontal stems called stolons that spread along the ground, forming new plants at each node. This allows the grass to rapidly cover a large area, making it useful for ground cover. Cynodon plectostachyus is also known as "African Bermuda grass" and is commonly used for grazing livestock and erosion control.
Question 30 Report
The effects of high environmental temperature on dairy cows include the following except
Answer Details
The correct option is "high feed intake." High environmental temperature has several negative effects on dairy cows, including fever, high water intake, low milk production, and restlessness. Heat stress caused by high temperatures can lead to decreased milk yield, reduced fertility, and increased susceptibility to diseases. In response to high temperatures, cows may also reduce their feed intake, which can further decrease milk production and cause weight loss. Therefore, high feed intake is not an effect of high environmental temperature on dairy cows.

Refrigerators are used for preserving agricultural produce and require electricity to run the compressor that maintains low temperatures inside the refrigerator. Therefore, options A is the correct answer.
Question 37 Report
Which of the following is the correct function of the gizzard?
Answer Details
The correct function of the gizzard is grinding of food. The gizzard is a muscular organ in the digestive tract of birds that contains small stones or grits which help in grinding and crushing food particles into smaller pieces. The muscular walls of the gizzard contract and relax, squeezing and grinding the food against the grits or stones, breaking it down into smaller pieces that can be easily digested and absorbed by the bird's digestive system. This process of mechanical digestion is important for birds because they do not have teeth to chew their food like mammals. Therefore, the gizzard serves as a bird's teeth, helping to break down tough food materials such as seeds, grains, and insects.
Question 38 Report
Which of the following does not fit into the agricultural use of land?
Answer Details
The option that does not fit into the agricultural use of land is "mining". Agriculture is the practice of cultivating land, raising animals, and producing food, fiber, and other products to sustain human life. Mining, on the other hand, involves the extraction of minerals and other valuable materials from the earth's surface. While agriculture involves the management of land for the purpose of producing food and other agricultural products, mining does not involve the same type of land management and is not typically considered an agricultural practice.

The system of growing arable crops at the early stage of forest establishment is referred to as
Answer Details
The system of growing arable crops at the early stage of forest establishment is referred to as the "Taungya System". This system involves the clearing of forest land for the purpose of establishing new forests. However, during the early stage of forest establishment, farmers are allowed to plant crops such as maize, cassava, and yams in between the newly planted trees. This helps to reduce the cost of establishing a new forest while also providing income for the farmers. The crops are usually grown for a few years until the trees have grown enough to provide sufficient shade, after which the farmers are required to stop planting crops and focus solely on tending the trees. The system is named after a practice used in Myanmar (formerly Burma) and is now widely used in many tropical countries.
