Question 6 Report
Which of the following is a friend of farmer
Answer Details
A friend of a farmer is the earthworm. Earthworms are beneficial to farmers because they help to improve soil fertility. They do this by consuming organic matter in the soil and excreting it as nutrient-rich castings that can be absorbed by plants. Additionally, earthworms burrow through the soil, creating channels for air and water to flow, which can help to increase soil aeration and drainage. This leads to a healthier soil structure, which can result in better plant growth and higher crop yields. For these reasons, earthworms are often referred to as "nature's tillers" and are considered to be valuable allies for farmers.
Question 7 Report
The main source of power for subsistence agriculture is
Answer Details
The main source of power for subsistence agriculture is man. Subsistence agriculture is a type of farming where the farmers grow crops and raise livestock for their own needs, rather than for sale. In this type of agriculture, the main source of power for planting and harvesting crops and caring for livestock is human labor. This can include manual labor such as plowing fields with a hand plow, planting seeds by hand, and carrying heavy loads.
Question 8 Report
The hormone responsible for milk let down in female farm animals is
Answer Details
The hormone responsible for milk let down in female farm animals is oxytocin. Oxytocin is produced by the pituitary gland and is released into the bloodstream when the animal is ready to nurse its young or be milked. When oxytocin is released, it stimulates the contraction of the muscles in the mammary glands, causing the milk to flow from the teat. This hormone plays a crucial role in the lactation process and is essential for providing nourishment to the young in many species of mammals, including cows, goats, and sheep. The release of oxytocin can also be triggered by the stimulation of the teats, such as when a calf or kid suckles or when a milker applies a milking machine to the teat, making it a key player in the dairy industry.

Subsistence agriculture is characterized by
Answer Details
Subsistence agriculture is characterized by small farm holdings and the production of food for the farmer's own use and consumption. Subsistence agriculture is a type of farming that is practiced on a small scale and is focused on providing food and basic necessities for the farmer and their family, rather than producing crops for sale or trade. Subsistence farmers typically cultivate small plots of land and use simple tools and techniques to grow crops and raise animals. In contrast, large scale agriculture is characterized by the use of machines and intensive use of inputs, such as fertilizers and pesticides, to maximize production and increase profits. While subsistence agriculture can provide food security for the farmer and their family, it can also result in low yields and limited economic opportunities. On the other hand, large scale agriculture can be more efficient and profitable, but can also lead to environmental degradation and social inequalities.
Question 13 Report
Which of the following is not a characteristic of metamorphic rock?
Question 14 Report
An increase in supply of agricultural produce can be caused by the following factors except
Answer Details
An increase in supply of agricultural produce can be caused by a variety of factors such as reduced cost of production, favorable weather conditions, and reduced taxation. However, the factor that does not contribute to an increase in supply is consumers buying less products. When consumers buy less products, it creates a surplus of the unsold produce and reduces demand for it. When demand for a product decreases, the market price for the product decreases as well, which can lead to a reduction in the supply of that product. In this case, the decrease in consumer demand would actually lead to a decrease in the supply of agricultural produce, rather than an increase.
Question 15 Report
Which of the following is not an example of edaphic factors?

The initial cost of the tractor is ₦50,000, and the depreciation value after a year of use is ₦10,580. To calculate the salvage value, we subtract the depreciation value from the initial cost: ₦50,000 - ₦10,580 = ₦39,420 Therefore, the salvage value of the tractor after a year of use is ₦39,420.
Question 19 Report
Root-knot disease of tomato is caused by
Answer Details
Root-knot disease of tomato is caused by a type of parasitic nematode. Nematodes are microscopic, worm-like organisms that can infect the roots of plants. In the case of root-knot disease of tomato, the nematodes feed on the roots of the plant, causing knots or galls to form. This can result in reduced growth, reduced yields, and in severe cases, death of the plant. The nematodes can survive in the soil for long periods of time and they can infect a wide range of plants, including tomatoes, peppers, melons, and many others. To control root-knot disease, it is important to practice good crop rotation, avoid planting susceptible crops in infested soil, and use nematicides if necessary.
Question 20 Report
Layer's ration contains more limestone than grower's ration because limestone
Answer Details
Layer's ration contains more limestone than grower's ration because limestone supplies sufficient minerals to layers for shell formation. Layers are chickens that are specifically raised for egg production, while growers are chickens that are raised for meat production. The composition of the feed for these two types of chickens is different, with layer's ration containing more calcium in the form of limestone. Calcium is an essential mineral for the formation of eggshells, and it is important for layers to have a constant supply of calcium in their diet. The higher level of limestone in layer's ration helps to ensure that the layers have access to the calcium they need for strong and healthy eggshells. On the other hand, growers do not require as much calcium in their diet as layers, so their ration contains less limestone.
Question 21 Report
The horizon of a soil profile which encourages the greatest level of microbial activity is
Answer Details
The horizon of a soil profile that encourages the greatest level of microbial activity is the A horizon. Soil horizons are defined layers in a soil profile, each with its own distinct physical and chemical properties. The A horizon, also known as the topsoil, is the topmost layer of the soil profile and is typically rich in organic matter, nutrients, and water. This layer is also where the majority of soil microbes, such as bacteria, fungi, and other microorganisms, are found. The B horizon, also known as the subsoil, is below the A horizon and is typically more compact and less porous than the A horizon. It contains relatively low levels of organic matter and is not as conducive to microbial activity as the A horizon. The C horizon is the layer of soil material that is below the B horizon and is composed of partially weathered rock fragments and mineral particles. This layer typically has low levels of organic matter and is not as conducive to microbial activity as the A horizon. The D horizon is not present in all soils and is typically composed of consolidated bedrock. This layer is not conducive to microbial activity as it is typically inhospitable to life due to its lack of water and organic matter. So, the answer to the question is the A horizon.

Question 31 Report
If 100 pieces of pests is attacking an hectare of cocoa farm and 25% suddenly died while 40% of the remnant is sent for medical examination. What is the number of pest remaining?
Answer Details
Let's first find out how many pests there were before 25% died. If 100 pests are attacking an hectare of cocoa farm, and 25% of them suddenly died, then 100 * 25/100 = 25 pests died. So, before 25% of the pests died, there were 100 pests. And after 25% died, there were 100 - 25 = 75 pests left. Next, let's find out how many pests were sent for medical examination. If 40% of the 75 pests that were left were sent for medical examination, then 75 * 40/100 = 30 pests were sent for medical examination. So, the number of pests remaining after some were sent for medical examination is 75 - 30 = 45 pests. Therefore, the answer is 45 pests.
Question 32 Report
If urea fertilizer contains 46% nitrogen, calculate the amount of nitrogen in 25kg bag of fertilizer?
Answer Details
The amount of nitrogen in a 25kg bag of urea fertilizer can be calculated by multiplying the total weight of the bag by the percentage of nitrogen in the fertilizer. Since the urea fertilizer contains 46% nitrogen, we can express this as a decimal: 46% = 0.46. Next, we multiply the total weight of the bag (25kg) by the decimal equivalent of the nitrogen content (0.46): 25kg * 0.46 = 11.5kg So, a 25kg bag of urea fertilizer contains approximately 11.5kg of nitrogen.
Question 33 Report
Rocks formed by the cooling and solidification of molten rocks called magma ejected from beneath the earth's crust is
Answer Details
The correct answer is: Igneous rock. Igneous rock is a type of rock that forms from the solidification of magma or lava. Magma is molten rock that is found underneath the Earth's crust. When the magma rises to the surface and cools down, it solidifies into a rock that we call igneous rock. Examples of igneous rocks include granite, basalt, and pumice. Metamorphic rock, on the other hand, is a type of rock that forms from the alteration of existing rocks due to heat, pressure, and/or chemical processes. These rocks are transformed from one type of rock into another. Sedimentary rock is a type of rock that forms from the accumulation and compression of sediment, such as sand, mud, and other organic materials. These rocks are often found in layers and can contain fossils. Caleima rock is not a recognized type of rock.

Question 35 Report
If 200 layers will consume 25kg of feed per day. Calculate the amount of feed consumed by a layer per day.
Answer Details
The amount of feed consumed by a layer per day is 0.125kg/day. This can be calculated by dividing the total amount of feed consumed by 200 layers, which is 25kg, by the number of layers, which is 200. This gives us 25 / 200 = 0.125kg/day. So, each layer consumes an average of 0.125kg of feed per day.
Question 36 Report
The practice of mating closely related animals is called
Answer Details
The practice of mating closely related animals is called inbreeding. Inbreeding is when two animals that are closely related, such as siblings or parent and offspring, are bred together. This increases the likelihood that their offspring will have similar traits and characteristics because they share many of the same genes. While inbreeding can lead to the expression of desirable traits, it can also increase the risk of genetic disorders and other health problems. For this reason, many breeders prefer to use outbreeding, or mating animals that are not closely related, to promote genetic diversity and reduce the risk of health problems in their offspring.
Question 37 Report
Which of the following constitutes subsidy in agricultural enterprise?
Answer Details
A subsidy in agricultural enterprise is a financial benefit provided by the government to support the agricultural sector. It can take many forms, but one example is the supply of fertilizers to farmers at a reduced price. In this scenario, the government reduces the cost of fertilizers for farmers by providing subsidies, making it more affordable for them to purchase the necessary inputs to grow their crops. This helps to improve the overall productivity and competitiveness of the agricultural sector, and can have a positive impact on the lives of farmers and the local economy. The other options listed (borrowing of money from a thrift society, provision of money to farmers through commercial banks, and provision of services through cooperative societies) are not considered subsidies in the strictest sense. However, they may still provide valuable support to farmers and the agricultural sector in other ways.
